COURT OF TAX APPEALS (CTA)

A WDL CANNOT BE TREATED AS THE CIR’S FINAL DECISION ON A PENDING ASSESSMENT PROTEST; HOWEVER, THE CTA MAY REVIEW THE VALIDITY OF THE WDL AS A SEPARATE COLLECTION MATTER. The CTA has exclusive appellate jurisdiction over decisions of the Commissioner of Internal Revenue (CIR) involving disputed assessments and other matters arising under the NIRC, which are distinct and separate matters; under the ruling, issuances related to collection efforts, such as a Warrant of Distraint and/or Levy (WDL), can no longer be treated as the CIR’s final decision on a pending protest to an assessment. In this case, the taxpayer filed a Petition for Review after receiving the WDL while his Motion for Reconsideration of the FDDA remained pending, rendering his challenge to the assessment premature and beyond the CTA’s jurisdiction; however, the CTA had jurisdiction over the WDL itself as a separate collection matter, and the Petition for Review was timely filed within the prescribed 30-day period from receipt. Accordingly, the CTA could not rule on the validity of the assessment but could act on the taxpayer’s request to quash, cancel, or lift the WDL. (Herbert P. Lipana v. Commissioner of Internal Revenue, CTA Case No. 11199, May 4, 2026)

A WDL IS VOID WHEN ISSUED WHILE A VALID PROTEST TO AN ASSESSMENT REMAINS PENDING, AS NO DELINQUENT TAXES EXIST TO JUSTIFY SUMMARY COLLECTION. The CIR may resort to distraint to collect delinquent taxes; however, summary collection remedies may not be enforced while a valid protest against an assessment remains pending, as the taxes are not yet delinquent and no final and executory assessment exists as the basis for collection. In this case, the CIR issued the WDL while the taxpayer’s protest to the FDDA remained pending, rendering the WDL void for lack of delinquent taxes to justify the collection remedy. The CTA clarified that this ruling did not determine the validity of the assessment, which remained pending before the CIR, but the Court had jurisdiction to declare the WDL void under its jurisdiction over other matters arising under the NIRC. (Herbert P. Lipana v. Commissioner of Internal Revenue, CTA Case No. 11199, May 4, 2026)

THE EXTRAORDINARY PRESCRIPTIVE PERIOD CANNOT APPLY WITHOUT COMPLIANCE WITH DUE PROCESS REQUIREMENTS AND PRIMA FACIE EVIDENCE OF FRAUD; THUS, THE ASSESSMENTS AND COLLECTIONS BARRED BY THE ORDINARY PRESCRIPTIVE PERIODS WERE TIME-BARRED. The extraordinary 10-year period for assessment and 5-year period for collection may apply only when the legal and due process requirements are satisfied, including clearly notifying the taxpayer of the basis for invoking the extended period and establishing prima facie evidence of falsity or fraud. In this case, the CIR failed to inform the taxpayer in the assessment notices that the extraordinary prescriptive period was being invoked, used the ordinary 25% surcharge instead of the 50% surcharge for fraud, and failed to establish prima facie evidence of a false or fraudulent return. Accordingly, the ordinary prescriptive periods applied, resulting in the prescription of the withholding tax on compensation (WTC) and expanded withholding tax (EWT) assessments, as well as the prescription of the right to collect the subject deficiency taxes because the Commissioner’s Answer seeking payment was filed beyond the applicable collection period. (Hizon Laboratories, Inc. v. Commissioner of Internal Revenue, CTA Case No. 10318, May 14, 2026)

A REQUEST FOR REINVESTIGATION SUSPENDS PRESCRIPTION ONLY IF GRANTED BY THE CIR; SINCE THE TAXPAYER SOUGHT RECONSIDERATION AND NO GRANT WAS PROVEN, THE RIGHT TO ASSESS AND COLLECT HAD PRESCRIBED. The prescriptive periods for assessment and collection are suspended only when a taxpayer requests a reinvestigation and the CIR or an authorized representative grants the request. In this case, the taxpayer’s protest to the FAN expressly sought reconsideration, not reinvestigation, and the CIR failed to present evidence that any request for reinvestigation had been granted, despite subsequent internal communications regarding the continuation of the investigation. Accordingly, the prescriptive periods continued to run and lapsed, barring the CIR’s right to assess and collect the deficiency taxes. The Court must dismiss a claim that is barred by prescription, even motu proprio, and tax prescription rules must be construed liberally in favor of the taxpayer. (Hizon Laboratories, Inc. v. Commissioner of Internal Revenue, CTA Case No. 10318, May 14, 2026)

SALES TO SBMA-REGISTERED ENTITIES QUALIFY FOR ZERO-PERCENT VAT WHEN THE GOODS ARE DELIVERED AND CONSUMED WITHIN THE SBFZ, AS PROVEN BY REGISTRATION CERTIFICATES AND SALES INVOICES ACKNOWLEDGING RECEIPT WITHIN THE ZONE. Sales of goods and services to duly registered entities operating within the Subic Bay Freeport Zone (SBFZ) may qualify for zero-percent VAT under the Cross-Border Doctrine and Destination Principle, provided that the seller is VAT-registered, the buyer is registered with the Subic Bay Metropolitan Authority (SBMA), and the goods are consumed or services rendered within the SBFZ. In this case, the taxpayer established that it was VAT-registered and presented certificates of registration and tax exemption covering the relevant taxable period. The sales invoices also identified the vehicles or parts sold, delivery dates and destinations, and acknowledgments of receipt by the buyer’s personnel within the SBFZ, sufficiently proving that the locus of the transactions was within the freeport zone. Accordingly, the sales qualified for zero-percent VAT. [Commissioner of Internal Revenue v. Ford Group Philippines, Inc., CTA En Banc Case No. 3046 (CTA Case No. 10316), May 19, 2026]

THE PREMATURE ISSUANCE OF THE FLD/FAN BEFORE THE EXPIRATION OF THE 15-DAY PAN RESPONSE PERIOD VIOLATES DUE PROCESS AND RENDERS THE ASSESSMENTS VOID, WHILE THE 60-DAY DOCUMENT SUBMISSION RULE APPLIES ONLY TO REQUESTS FOR REINVESTIGATION. The CTA has jurisdiction over a timely appeal, the 60-day period for submitting supporting documents applies only to requests for reinvestigation and not reconsideration, and the taxpayer must be afforded the mandatory 15-day period to respond to a PAN before the issuance of a FLD/FAN. In this case, the taxpayer’s protest was expressly a request for reconsideration, making the 60-day document submission rule inapplicable, while the petition for review filed on May 19, 2021 was timely under the extended deadline. The Court also ruled that the validity of the LOA could be challenged for the first time on appeal because it involved a matter of record and procedural due process. However, the BIR had issued the FLD/FAN before the taxpayer’s 15-day period to respond to the PAN expired, despite the taxpayer’s timely response to the PAN. This premature issuance violated procedural due process and rendered the deficiency tax assessments void, which could not be cured by the subsequent protest. Accordingly, the Court cancelled the deficiency assessments and enjoined their collection. (Maquinit Realty & Development Corp. v. Commissioner of Internal Revenue, CTA Case No. 10518, May 26, 2026) 

SERVICE OF THE PAN ON THE TAXPAYER’S AUTHORIZED ATTORNEY-IN-FACT IS BINDING, SATISFYING THE REQUIRED 15-DAY RESPONSE PERIOD BEFORE ISSUANCE OF THE FLD/FAN. The taxpayer must be afforded a 15-day period to respond to the PAN before the issuance of the FLD/FAN. In this case, although the taxpayer claimed that the PAN and FLD/FAN were served simultaneously, the records established that the PAN had initially been served on his attorney-in-fact at the BIR office on November 29, 2022, while the FLD/FAN was served on the taxpayer on January 17, 2023. The Court held that the initial service of the PAN upon the authorized attorney-in-fact was binding on the taxpayer, and the attorney-in-fact’s failure to inform him of its receipt could not be attributed to the BIR. Accordingly, the taxpayer was afforded the required 15-day period to respond to the PAN, and the issuance of the FLD/FAN did not violate his right to due process. (Mark Louie L. Tigue v. Commissioner of Internal Revenue, CTA Case No. 11347, June 23, 2026)

A PROTEST THAT FAILS TO MEET THE FORMAL REQUIREMENTS IS VOID, RENDERING THE TAX ASSESSMENTS FINAL AND EXECUTORY, BUT COMPROMISE PENALTIES REQUIRE THE TAXPAYER’S CONSENT. A valid protest against a FLD/FAN must state the nature of the protest, the date of the assessment notice, and the applicable law, rules, regulations, or jurisprudence supporting the protest; otherwise, the protest is void and the assessment becomes final and executory. In this case, the taxpayer’s protest failed to identify the date of the assessment notice and the legal basis for disputing the assessment, and did not explain how the subsequently submitted receipts, invoices, and accounting records related to the assessed deficiencies. Consequently, the protest was invalid, the income tax, value-added tax, and expanded withholding tax assessments became final and executory, and the issuance of the Warrant of Garnishment to collect them was proper. However, the Court cancelled the compromise penalties because these require the taxpayer’s agreement and cannot be unilaterally imposed. (Mark Louie L. Tigue v. Commissioner of Internal Revenue, CTA Case No. 11347, June 23, 2026)

A CERTIFICATE OF TAX EXEMPTION FOR A COOPERATIVE IS MERELY CONFIRMATORY AND ITS ABSENCE DOES NOT AUTOMATICALLY DEFEAT A COOPERATIVE’S TAX EXEMPTION. A duly registered cooperative’s entitlement to tax exemption depends on compliance with the statutory requirements, and a Certificate of Tax Exemption (CTE) issued by the BIR serves only as confirmation of such entitlement, not as its source. In this case, although the cooperative obtained an amended CDA registration reflecting its changed name and expanded activities, it failed to secure a new CTE. The Court held that this omission alone did not defeat its entitlement to tax exemption because the law does not require a separate certification as a condition for exemption, and the Joint Rules could not impose an additional requirement beyond the statute. However, the absence of a CTE did not automatically invalidate the assessments; the Court still had to determine whether the cooperative qualified for exemption based on its actual transactions with members and non-members.

BIR DEADLINES FROM OCTOBER 19, 2026 TO OCTOBER 25, 2026. A gentle reminder on the following deadlines, as may be applicable:

COURT OF TAX APPEALS (CTA)

AN LOA IS REQUIRED ONLY FOR THE EXAMINATION AND ASSESSMENT UP TO THE FAN; WHERE THE LOA-AUTHORIZED GS AND RO COMPLETED THOSE STAGES, AN RO MAY VALIDLY PARTICIPATE IN THE SUBSEQUENT REINVESTIGATION UNDER AN MOA, WITHOUT AFFECTING THE VALIDITY OF THE ASSESSMENT. A Letter of Authority (LOA) is required for the examination of a taxpayer and assessment of deficiency taxes up to the issuance of the Formal Letter of Demand/Final Assessment Notice (FLD/FAN) but is not required for a reinvestigation conducted after the FAN, for which authority under a Memorandum of Assignment (MOA) is sufficient. The examination and assessment culminating in the FAN were conducted by the Group Supervisor (GS) and Revenue Officer (RO) named in the LOA, while another RO participated only after the case was reassigned for reinvestigation pursuant to an MOA following taxpayer’s Request for Reinvestigation. Thus, RO’s authority under the MOA was sufficient, and any possible defect in the reinvestigation would affect only the FDDA, not the validity of the assessment itself. Accordingly, the assessment against the taxpayer was held valid. [Intelligent Touch Corporation v. Commissioner of Internal Revenue, CTA En Banc Case Nos. 2966 and 2969 (CTA Case No. 10215), April 10, 2026]

AN LOA MUST NAME THE RO AUTHORIZED TO CONDUCT THE AUDIT; THUS, THE ASSESSMENT WAS VOID WHEN THE REASSIGNED OFFICERS ACTED ONLY UNDER AN MOA. An LOA is a due process and jurisdictional requirement, and only the revenue officers specifically named therein may conduct the examination unless a new or amended LOA is issued. In this case, the audit was conducted by revenue officers whose authority was based only on an MOA issued by a subordinate official, which could not validly amend or substitute the original LOA; thus, the assessment was void for lack of authority of the examining officers. [Commissioner of Internal Revenue v. Banclife Insurance Co., CTA En Banc Case No. 2860 (CTA Case No. 9939), June 9, 2026] 

ACTUAL RECEIPT OF THE LOA AND PAN BY THE TAXPAYER OR ITS AUTHORIZED REPRESENTATIVE ESTABLISHES PROPER SERVICE. If a taxpayer categorically denies receipt of a Preliminary Assessment Notice (PAN), the burden shifts to the CIR to prove its actual receipt by the taxpayer or its authorized representative. In this case, the CIR discharged this burden by presenting the actual LOA received by taxpayer’s Authorized Representative, on August 23, 2012, and the PAN received by the taxpayer’s HR Assistant, on October 22, 2014; Taxpayer’s failure to question their authority in its Request for Reinvestigation and Administrative Appeal, its delayed assertion of the issue only in the Petition for Review, and the lack of personal knowledge of its witness regarding the recipients supported the finding that the allegation was an afterthought. Since the LOA and PAN were personally served and acknowledged through signed receiving copies, constructive service under RR No. 12-99 was inapplicable.  [Intelligent Touch Corporation v. Commissioner of Internal Revenue, CTA En Banc Case Nos. 2966 and 2969 (CTA Case No. 10215), April 10, 2026]

A FORMAL LETTER OF DEMAND AND ASSESSMENT NOTICE THAT FAILS TO CONTAIN A CATEGORICAL DEMAND FOR PAYMENT WITHIN A DEFINITE PERIOD IS VOID.  A FLD/FAN must contain a clear and categorical demand for payment within a definite period; otherwise, the assessment is void. In this case, the FLD/FAN issued to the taxpayer merely stated that it could pay the assessment but did not impose a definite due date or categorical demand for payment, and the subsequent FDDA containing a payment deadline could not cure the defect because the FLD/FAN and FDDA serve different functions. Thus, the assessments were held void and without legal effect. [Commissioner of Internal Revenue v. Travellers International Hotel Group, Inc., CTA En Banc Case No. 3007 (CTA Case No. 10445), June 11, 2026]

WHEN RECEIPT OF THE PAN AND FAN/FLD IS DENIED, THE CIR MUST PROVE ACTUAL RECEIPT; HERE, ITS FAILURE TO DO SO RENDERS THE ASSESSMENT VOID. The 30-day period to protest an assessment begins only upon the taxpayer’s actual receipt of the FAN/FLD; thus, when receipt is categorically denied, the burden shifts to the CIR to prove actual receipt. In this case, the taxpayer consistently denied receiving the PAN and FAN/FLD, but the CIR presented only registry receipts proving mailing and failed to provide the registry return cards, postmaster certification, or other competent proof of actual receipt. Accordingly, the assessment did not become final and executory, and the lack of proper service deprived taxpayer of due process, rendering the assessment void and allowing the CTA to acquire jurisdiction over its petition. [Commissioner of Internal Revenue v. Banclife Insurance Co., CTA En Banc Case No. 2860 (CTA Case No. 9939), June 9, 2026] 

THE EXTRAORDINARY TEN-YEAR PERIOD FOR TAX ASSESSMENT CANNOT BE INVOKED INCONSISTENTLY WITH THE TAXPAYER’S RIGHT TO DUE PROCESS. The extraordinary 10-year period to assess deficiency taxes applies only in cases of a false or fraudulent return with intent to evade tax, and its invocation must comply with due process requirements. In this case, the CIR simultaneously relied on a waiver extending the ordinary three-year period and invoked the 10-year period for alleged substantial under-declaration, thereby misleading the taxpayer as to the applicable prescriptive period. Since the CIR’s inconsistent invocation of the two periods rendered the 10-year period inapplicable, the ordinary three-year period governed and had already lapsed when the assessment was issued. (Russ Reuben L. Piczon v. Commissioner of Internal Revenue, CTA Case No. 10753, June 17, 2026).

FAILURE TO SUBMIT ADDITIONAL DOCUMENTS DURING REINVESTIGATION DOES NOT BAR THE TAXPAYER FROM PRESENTING THEM BEFORE THE CTA; SEE DISSENTING OPINION. A taxpayer requesting reinvestigation must submit all relevant supporting documents within 60 days from the filing of the protest; otherwise, the assessment becomes final at the administrative level, barring the taxpayer from disputing the assessment before the BIR through newly discovered or additional evidence. However, such finality does not prevent the taxpayer from elevating the case to the CTA, where proceedings are conducted de novo and new or additional evidence may be presented. Thus, although the taxpayer failed to submit its invoices and receipts during reinvestigation, the failure merely warranted the denial of its Request for Reinvestigation and issuance of the FDDA, without barring the CTA from considering the additional documents presented during trial. In contrast, the dissenting opinion maintains that failure to submit the required documents within the prescribed period renders the assessment final and executory, leaving no valid disputed assessment for the CTA to review; consequently, the CTA Division lacked jurisdiction and the Petition for Review should have been dismissed. [Intelligent Touch Corporation v. Commissioner of Internal Revenue, CTA En Banc Case Nos. 2966 and 2969 (CTA Case No. 10215), April 10, 2026]

EXCESS INPUT TAX CARRIED OVER FROM A TAXABLE PERIOD MUST BE DEDUCTED FROM OUTPUT TAX IN THE SUCCEEDING PERIOD, NOT USED TO REDUCE THE CURRENT PERIOD’S VAT DEFICIENCY. Under the rules governing the carry-over of excess input tax, excess input tax from one taxable period is intended to be carried over and applied as a deduction against output tax in the succeeding taxable period, rather than used to reduce the VAT deficiency of the current period. In this case, the taxpayer’s excess input tax from TY 2011 was properly deducted from the allowable input tax in computing its TY 2011 deficiency VAT, not as a disallowance, but to preserve its proper treatment as input tax carried over for use against output tax in TY 2012. Allowing the amount to reduce the TY 2011 deficiency while also permitting taxpayer to use the same amount against its TY 2012 output tax would result in a double benefit, contrary to the purpose of excess input tax carry-over. [Intelligent Touch Corporation v. Commissioner of Internal Revenue, CTA En Banc Case Nos. 2966 and 2969 (CTA Case No. 10215), April 10, 2026] 

CERTIORARI CANNOT BE USED TO REVIEW ERRORS OF JUDGMENT OR REWEIGH EVIDENCE, ABSENT GRAVE ABUSE OF DISCRETION. Certiorari is limited to correcting errors of jurisdiction or grave abuse of discretion and does not lie to review the intrinsic correctness of a lower court’s factual or legal findings; here, the People merely sought to reweigh the evidence and challenge the RTC-Pasig’s finding that the taxpayer’s issuance of Philippine Depositary Receipts (PDRs) was an investment transaction not shown to be subject to VAT, which constituted an alleged error of judgment rather than a jurisdictional error. Moreover, reviewing the acquittal would violate the constitutional protection against double jeopardy, absent due process deprivation or grave abuse of discretion, neither of which was present. Thus, the CTA En Banc denied the Petition and affirmed the CTA Division’s dismissal of the certiorari petition. [People of the Philippines v. Hon. Ana Teresa T. Cornejo-Tomacruz, et al., CTA En Banc Case No. 3037 (CTA SCA Case No. 0014), May 28, 2026].

ELECTRIC COOPERATIVES REGISTERED WITH THE NEA REMAIN PERMANENTLY EXEMPT FROM INCOME TAX UNDER PD NO. 269; HERE, MORESCO-I’S NEA REGISTRATION QUALIFIED IT FOR THE EXEMPTION. Electric cooperatives registered with the National Electrification Administration (NEA) are permanently exempt from income tax, and such exemption was not repealed by the Cooperative Code, as amended by Republic Act No. 9520, which expressly preserved PD No. 269; here, respondent’s Certificate of Registration established that it was registered with the NEA, thereby qualifying it for the permanent income tax exemption under PD No. 269.

BIR DEADLINES FROM OCTOBER 12, 2026 TO OCTOBER 18, 2026. A gentle reminder on the following deadlines, as may be applicable:

COURT OF TAX APPEALS (CTA)

BIR’S ASSESSMENT IS CONCLUSIVE IF TAXPAYER FAILED TO FILE PROTEST WITHIN THE 30-DAY PERIOD; BUT BIR’S COLLECTION EFFORT MUST BE WITHIN THE 5-YEAR PERIOD FROM FLD/FAN ISSUANCE. The CTA has jurisdiction not only over disputed assessments but also over other matters arising under the NIRC, including BIR collection measures such as the levy and auction of real property; while a taxpayer generally has 30 days to protest an FLD/FAN, failure to do so makes the assessment final, executory, and demandable, but the finality of the assessment is distinct from the prescriptive period for its collection. Applying these rules, the CTA acquired jurisdiction because taxpayer timely filed its Petition and no prior administrative protest was necessary because the appeal concerned the BIR’s collection action rather than a disputed assessment. However, the deficiency EWT and DST assessments under the FLD/FAN were already conclusive because taxpayer failed to file a valid administrative protest within 30 days, thereby precluding it from subsequently challenging the assessments on their merits. Nevertheless, the BIR could no longer collect the assessed taxes because where the taxpayer failed to file the relevant returns, the BIR may assess within 10 years, but once an assessment is made, it must collect the assessed tax by distraint, levy, or court proceeding within five years from the assessment. Since taxpayer presented no evidence that it had filed the pertinent tax returns, the 10-year assessment period applied; nevertheless, the five-year collection period commenced upon service of the FLD/FAN. The BIR’s Warrant of Distraint and/or Levy was issued and the BIR seeking collection was filed only beyond the five-year period. the CTA held that prescription of collection may still be examined even though the assessment itself had become final and conclusive (City Government of Iligan v. Commissioner of Internal Revenue, CTA Case No. 11036, April 23, 2026)

QUESTIONS ON INTERLOCUTORY ORDERS OF THE CTA SHOULD BE RAISED WITH THE SUPREME COURT, NOT CTA EN BANC. The CTA En Banc has appellate jurisdiction only over final judgments, resolutions, or orders of a CTA Division, particularly resolutions on motions for reconsideration or new trial, and does not have jurisdiction over interlocutory orders issued while a case remains pending. An order is interlocutory when it resolves only a procedural or preliminary matter and leaves something further to be decided before the case can be finally disposed of. Applying these rules, the CTA En Banc held that the resolutions denying taxpayer’s request for an extension to file its Formal Offer of Evidence were interlocutory because they did not determine the merits of the case or terminate the proceedings; the CTA Division still had to continue hearing and resolve the main case, En Banc cannot entertain an appeal from an interlocutory ruling, nor may it exercise supervisory or certiorari jurisdiction over a CTA Division simply because the latter is conducting ongoing proceedings. This limitation prevents piecemeal appeals and unnecessary disruption of trial proceedings. The aggrieved party may instead proceed with the case before the Division and, if the eventual final judgment is adverse, raise the interlocutory ruling as an assigned error in an appeal to the En Banc; in exceptional cases involving grave abuse of discretion amounting to lack or excess of jurisdiction, the proper remedy is a Rule 65 petition for certiorari directly with the Supreme Court, not an immediate appeal to the En Banc. Since the main proceedings in the CTA Division had not yet been concluded and no final judgment existed, the petition was premature and the CTA En Banc dismissed it for lack of jurisdiction [Aeon Credit Services (Philippines), Inc. v. CIR, CTA En Banc Case No. 3091 (CTA Case No. 10693), April 30, 2026]

BIR MUST PROVE ACTUAL RECEIPT OF FLD/FAN IF TAXPAYER DENIES RECEIPT. An assessment must comply with due process, including proper service of the PAN and FLD/FAN, and where the taxpayer denies receipt, the CIR bears the burden of proving actual receipt by competent evidence; an assessment cannot become final and executory without proper service and receipt. Applying these rules, the CTA En Banc sustained the cancellation of the deficiency VAT assessment because the taxpayer categorically denied receiving the FLD/FAN and the BIR failed to present substantial evidence establishing that it was properly served and actually received. Although the BIR argued that the FLD/FAN was mailed to respondent’s registered address in Parañaque, the records showed that the BIR itself had already personally served the LOA, NIC, and PAN at the taxpayer’s new Makati address, demonstrating that it knew where taxpayer was located. More importantly, the BIR’s reliance on the old registered address and its presentation of an LBC courier receipt alone did not sufficiently prove service because the rules require the server’s written report under oath detailing the manner, place, and date of service and the relevant courier information. The disputable presumption that a properly mailed letter was received was likewise overcome by the taxpayer’s categorical denial, shifting the burden back to the BIR to prove actual receipt. Thus, there was no valid assessment, and the subsequent WDL could not be enforced. [Commissioner of Internal Revenue v. Diamond Drilling Corporation of the Philippines, CTA EB No. 3151 (CTA Case No. 10661), May 4, 2026]

REVENUE OFFICERS’ (RO) AUTHORITY MUST BE FROM A LOA, NOT FROM MEMORANDUM OF ASSIGNMENT (MOA). A valid LOA is required to clothe RO with authority to examine a taxpayer and recommend deficiency tax assessments, and only the RO specifically named in the LOA may conduct the examination; reassignment or substitution of revenue officers requires a new or amended LOA. Applying these rules, the CTA En Banc held that it could rule on the RO’s lack of authority even though the issue was raised only on appeal, since the rules authorize the CTA to resolve related issues necessary for the orderly disposition of a case. Although an initial LOA was issued by the Assistant Commissioner, the actual examination was conducted by ROs whose authority purportedly arose from a MOA signed by a Chief who was not among the officials authorized to issue LOAs. the CTA En Banc affirmed the cancellation of the assessments and the refund of tax [Commissioner of Internal Revenue v. Central Luzon Drug Corporation, CTA EB No. 3111 (CTA Case No. 10045), May 8, 2026]

BUREAU OF INTERNAL REVENUE

Revenue Memorandum Circular No. 98-2026

BIR DEADLINES FROM SEPTEMBER 28, 2026 TO OCTOBER 4, 2026. A gentle reminder on the following deadlines, as may be applicable:

COURT OF TAX APPEALS (CTA) DECISIONS

LOA SERVED 860 DAYS AFTER ISSUANCE AND THE APPLICABLE 180-DAY AUDIT PERIOD HAD ALREADY EXPIRED RENDERS THE ASSESSMENT VOID. A revenue officer may examine a taxpayer and recommend a deficiency assessment only pursuant to a valid Letter of Authority (LOA), while the regulations require the LOA to be served within 30 days from issuance, otherwise it becomes null and void unless revalidated; consistent with this, the Supreme Court held that an unserved LOA that remains outstanding beyond 30 days becomes wholly unenforceable absent revalidation. Here, the LOA was served 860 days after issuance, with no showing that it had been revalidated. The Court therefore found that the LOA had already become void and unenforceable when served. Although the BIR regulations subsequently deleted the 30-day service requirement, and clarified that an LOA served beyond 30 days may still be considered valid, the Circular expressly limits this to cases where the applicable 180-day/240-day period for completion of the audit has not yet expired. That saving provision did not benefit the BIR because, when the LOA was eventually served, the 180-day audit period had already expired. The taxpayer’s failure to update its address and the BIR’s alleged difficulty in locating it likewise did not preserve the validity of the already expired LOA. Since the audit and examination were therefore conducted without a valid and enforceable LOA, the resulting deficiency assessment was void and ineffectual. (Floorcompany, Inc., v. Commissioner of Internal Revenue (“CIR”), CTA Case No. 11050, April 29, 2026)

LOA IS REQUIRED FOR AN ASSESSMENT OUTSIDE THE COVERED PERIOD; BIR CANNOT VALIDLY ARGUE THAT NEW LOA IS UNNECESSIARY FOR VAT ASSESSMENT DUE TO UTILIZATION OF EXCESS INPUT VAT. An RO may examine a taxpayer and perform assessment functions only pursuant to a valid LOA issued by the CIR or a duly authorized RD, and the LOA must identify the taxable period covered because it defines the extent of the RO’s authority and protects the taxpayer’s right to due process. The Supreme Court emphasized that an assessment made pursuant to an invalid LOA, or beyond the authority granted therein, is void and ineffectual; the RO cannot assess a taxpayer for a taxable period not covered by the LOA, since the RO must obtain another LOA if the BIR intends to expand the audit period. A LOA is required even when the BIR does not physically examine the taxpayer’s books, because the requirement depends on whether the taxpayer is subjected to an examination or audit, not on the manner by which the BIR obtains or verifies the information used in the assessment. Here, the BIR issued LOA authorizing the examination of books of accounts and other accounting records for all internal revenue taxes. Despite this limited authority, the BIR issued an Assessment Letter and a Denial of Protest for alleged deficiency VAT for the quarter ended June 30, 2021, a period clearly outside the coverage of the LOAs. The CIR argued that a new LOA was unnecessary because the deficiency VAT assessment resulted from utilization of excess input taxes rather than from an examination of books and accounting records. The Court rejected this argument, explaining that the BIR cannot avoid the LOA requirement simply by relying on information or systems that do not involve a physical examination of the taxpayer’s books; once the taxpayer is subjected to an examination or audit, the statutory requirement for prior authorization applies. Thus, the BIR should have issued another LOA specifically authorizing the examination and assessment for the quarter ended June 30, 2021. [CIR v. PMFTC, Inc., CTA EB No. 3009 (CTA Case No. 10714), April 13, 2026]

A TAXPAYER MAY BE TREATED AS CBL ONLY UPON PROOF OF THE REQUIRED BIR TAGGING AND PUBLICATION; THUS, WHERE THE BIR SHOWED ONLY CERTIFICATIONS OF UNSUCCESSFUL LOCATION EFFORTS BUT FAILED TO PROVE ACTUAL CBL DESIGNATION AND PUBLICATION, THE LOA REMAINED SUBJECT TO THE 30-DAY REVALIDATION AND 180-DAY AUDIT PERIODS, RENDERING IT AND THE RESULTING ASSESSMENTS VOID. A taxpayer may be given “Cannot Be Located” (CBL) status only after the BIR makes efforts to locate the taxpayer and obtains certifications from at least two specified offices or organizations that the taxpayer does not appear in their records; the taxpayer’s CBL status must then be reflected in the BIR records and submitted for publication on the BIR website and in at least two newspapers of general circulation. Here, although the BIR obtained certifications from the Makati City Business Permits Office and Barangays San Isidro and Bangkal indicating that taxpayer was not registered in their respective records, these certifications merely established efforts to locate taxpayer and did not prove that taxpayer was actually tagged as CBL in the BIR’s records. The only evidence offered was a Memorandum recommending that taxpayer be included in the CBL list and that the matter be referred for publication; the BIR presented no evidence that the CBL designation was actually made, or that taxpayer’s name was submitted and published on the BIR website and in at least two newspapers. The Court could not consider evidence that had not been formally offered. Consequently, the BIR failed to establish the factual predicate for exempting the LOA from the 30-day revalidation requirement and the 180-day audit-completion period. The LOA was therefore void, and because the assessments for taxable year 2017 were issued pursuant to an invalid LOA, they were likewise unenforceable and had to be cancelled and set aside. (Floorcompany, Inc., v. CIR, CTA Case No. 11050, April 29, 2026)

A WDL IS VALID ONLY WHEN THE TAX LIABILITY IS FINAL AND EXECUTORY; THUS, WDLS ARE PREMATURE BECAUSE THE TAXPAYER’S MR OF THE FDDA REMAINED PENDING; TAXPAYER CANNOT VALIDLY CHALLENGE THE ASSESSMENT FOR LACK OF A FINAL CIR DECISION. The Court of Tax Appeals has jurisdiction over “other matters” arising under the NIRC, including the validity of a Warrant of Distraint and/or Levy (“WDL”), but the BIR may resort to summary collection remedies only when the taxpayer’s liability has become delinquent, final, and executory, whether arising from self-assessed taxes or a final deficiency assessment. Here, the taxpayer received the second WDL and filed its Petition within the 30-day period; the first WDL was refused because its Motion for Reconsideration (“MR”) of the Final Decision on Disputed Assessment (“FDDA”) was still pending. The Court held that both WDLs were premature because the deficiency assessment had not become final and executory: the taxpayer timely protested the FLD/FAN, submitted supporting documents, and elevated the denial of its protest through an MR to the CIR. Collection through a WDL presupposes a final and executory liability; thus, the BIR could not enforce the assessment while the taxpayer’s administrative remedy remained pending. However, the Court could not rule on the merits of the deficiency assessment because, after denial of a protest by an authorized representative of the CIR, the taxpayer may either appeal to the CTA within 30 days or seek reconsideration from the CIR, and these remedies are mutually exclusive. Having chosen the latter, the taxpayer had to await the CIR’s action on its MR before seeking judicial review. Moreover, only one 180-day period is available for the CIR or his authorized representative to act, reckoned from submission of the supporting documents; the subsequent MR did not create a new 180-day period. Accordingly, the Court cancelled and set aside the WDLs and ordered the BIR to cease collection until the assessment becomes final and executory, but dismissed the Petition insofar as it sought review of the deficiency assessment, there being no final CIR decision on the pending MR. (Ivonclar Vivadent, Inc. v. CIR, CTA Case No. 11253, April 20, 2026)

TAXPAYER SHOULD APPEAL THE FDDA SIGNED BY THE CIR HIMSELF TO THE CTA; MOTION FOR RECONSIDERATION WILL NOT TOLL THE PERIOD. The CTA has jurisdiction over disputed assessments only when the taxpayer timely protests the assessment and timely appeals the CIR’s final decision to the CTA, while “other matters  include challenges to BIR collection remedies such as WDL and Warrant of Garnishment (“WOG”). Here, the CTA En Banc ruled that the original Petition for Review was only partly within the CTA’s jurisdiction. The FDDA signed by the CIR (Dulay) constituted the CIR’s final decision on taxpayer’s protest and the taxpayer should have appealed the FDDA to the CTA. Instead, taxpayer filed a letter-reply/motion for reconsideration with the CIR, which did not suspend or extend the period to appeal. Consequently, the assessments became final, executory, and demandable, depriving the CTA of jurisdiction to review their validity. The Court nevertheless recognized jurisdiction over the WOGs as “other matters.” The WDL, however, was challenged beyond the 30-day period; hence, the CTA had no jurisdiction over the WDL. In contrast, the WOGs were received within 30-day period deadline, giving the CTA jurisdiction over them. On the merits, the Court sustained the WOGs because taxpayer could not use a challenge to the collection remedy to indirectly reopen an assessment that had already become final. Taxpayer’s separate argument that the first LOA was invalid because it was served more than 30 days after issuance without revalidation was likewise rejected. The taxpayer did not object to the alleged defect when the LOA was served, nor did it raise the issue in its protest or original CTA petition; it surfaced only during cross-examination and was formally raised much later in a memorandum. Because the first LOA was valid, taxpayer’s challenge to the waivers extending the period to assess also failed. Accordingly, the CTA En Banc partially dismissed the Petition for lack of jurisdiction insofar as it sought nullification of the assessment and WDL, but denied it on the merits [Pentagon Gas Corporation v. CIR, CTA EB No. 3089 (CTA Case No. 10868), April 20, 2026]

15-DAY PERIOD TO FILE APPEAL TO CTA EN BANC IS RECKONED FROM DATE OF RECEIPT OF OSG, NOT BY THE BIR A Petition for Review to the CTA En Banc must be filed within 15 days from receipt of the Division’s resolution, with extension available only upon proper motion. Where the OSG is the government’s principal counsel, receipt by the OSG controls the appeal period, even if the resolution is received later by deputized BIR counsel. Thus, receipt by the OSG started the 15-day period, and petition filed by the BIR outside the 15-days period is dismissible. [CIR v. Sumitomo Corporation – Manila Branch, CTA EB No. 2998 (CTA Case No. 10412, April 7, 2026]

IN A DE NOVO CTA PROCEEDING, DOCUMENTS MERELY SUBMITTED DURING THE BIR AUDIT HAVE NO EVIDENTIARY VALUE ABSENT FORMAL OFFER; THUS, WHERE THE TAXPAYER FAILED TO FORMALLY OFFER THE ORS/SIS SUPPORTING ITS INPUT VAT CLAIM, THE CTA SUSTAINED THE DISALLOWANCE FOR FAILURE TO PROVE THE ASSESSMENT ERRONEOUS. The CTA is a court of record where cases are litigated de novo, requiring taxpayers to formally offer competent evidence to substantiate their claims; likewise, under the rules on evidence, allegations are not evidence and the burden of proof rests on the party asserting the claim. Here, the CIR disallowed input VAT because the supporting ORs and SIs were either missing or issued by non-VAT suppliers, and although taxpayer claimed that the documents were submitted during the BIR audit and that the amounts were instead treated as expenses/COS, it failed to formally offer the alleged ORs and SIs before the CTA. Since documents merely submitted to the BIR have no evidentiary value absent formal offer in court, taxpayer failed to prove that the assessment was erroneous; thus, the CTA sustained the disallowance of the unsupported input VAT (Joyland Industries Corporation v. CIR, CTA Case No. 11269, April 15, 2026)

INPUT VAT IS CREDITABLE ONLY UPON COMPLIANCE WITH PRESCRIBED INVOICING REQUIREMENTS. A taxpayer claiming input VAT must establish that the supporting VAT invoices/official receipts comply with the prescribed invoicing requirements, including the nature of payment/service, TIN, address, VAT breakdown, and other required details; input tax on local purchases of goods is creditable upon consummation of the sale, not upon payment. Here, the CTA found that taxpayer’s supporting invoices/receipts failed to comply with these requirements, and taxpayer could not shift the burden to its suppliers because it was incumbent upon it to exercise due diligence in ensuring that its documents were compliant; its cash-flow records also could not cure the absence of the required information. However, the Court cancelled the disallowance because the records showed that the taxpayer’s TIN was actually reflected in the supporting document. The Court likewise upheld the disallowance in “out-of-period” input VAT because the purchases involved goods acquired in a different year, for which the input tax became creditable upon consummation, rather than upon payment. Accordingly, the CTA sustained the invoicing-related disallowance (Joyland Industries Corporation v. CIR, CTA Case No. 11269, April 15, 2026)

TAXPAYER MUST CLEARLY RECONCILE ALLEGATION OF OVERCLAIMED INPUT VAT BY SUBMITTING RELEVANT AND VERIFIABLE SOURCE DOCUMENTS . The CTA is a court of record conducting trials de novo, and the taxpayer bears the burden of proving that an assessment is erroneous; assessments are prima facie presumed correct and made in good faith. Here, the BIR determined an overclaimed input VAT by comparing the Global Sources of Input Tax (GSIT) reflected in taxpayer’s AFS/AITR with the sources of input tax reported in its VAT returns. Although taxpayer presented reconciliations and claimed that its importation input VAT was supported by 664 pages of importation documents and that differences arose from the use of landed cost versus amounts recorded in the AFS/AITR, it failed to present the underlying importation documents and other supporting records necessary to verify these explanations and failed to adequately explain the variances in its reconciliations. Since the reconciliations, without the relevant source documents, could not be independently verified, and evidence not formally offered cannot be considered, taxpayer failed to discharge its burden of proving the assessment erroneous; thus, the CTA sustained the disallowance for overclaimed input tax. (Joyland Industries Corporation v. CIR, CTA Case No. 11269, April 15, 2026)

REVENUE ISSUANCES

Pursuant to Revenue Memorandum Circular (RMC) No. 97-2026 and under the National Internal Revenue Code (NIRC) of 1997, as amended, allowable system loss charges billed by electric distribution utilities to consumers are excluded from the 12% Value-Added Tax (VAT) computation to directly reduce end-user energy costs.

BIR DEADLINES FROM SEPTEMBER 21, 2026 TO SEPTEMBER 27, 2026. A gentle reminder on the following deadlines, as may be applicable:

COURT OF TAX APPEALS (CTA) DECISIONS

REASSIGNMENT OF AUDIT TO ANOTHER EXAMINER PRIOR TO THE PAN-STAGE REQUIRES A NEW LETTER OF AUTHORITY (LOA); MEMORANDUM OF ASSESSMENT ISSUED BY A REVENUE DISTRICT OFFICER IS NOT SUFFICIENT. The Tax Code requires that the examination of a taxpayer’s books be conducted only by revenue officers specifically authorized under a valid LOA; an LOA is a special authority granted to particular revenue officers, not a general authority that may be used by any BIR officer. The Supreme Court held that the reassignment or substitution of revenue officers without a new or amended LOA violates the taxpayer’s right to due process and usurps the statutory authority of the CIR or his duly authorized representative. Any reassignment or transfer of a case to other revenue officers requires the issuance of a new LOA. Here, the examiners, who conducted the examination and recommended the issuance of the PAN, were not authorized under a valid LOA; their supposed authority rested only on Memorandum of Assignment issued by the Revenue District Officer, which could not substitute for an LOA. The subsequent LOA likewise did not cure the defect because it was issued long after the PAN. Thus, the PAN issued based on the unauthorized examination was void for lack of valid authority and violation of due process. [(Ammex I-Support Corporation v. Commissioner of Internal Revenue (CIR), CTA Case No. 11192, April 17, 2026)]

PHRASES IN THE ASSESSMENT NOTICE “YOU ARE REQUESTED TO PAY” OR “IF YOU ARE AMENABLE” DO NOT NEGATE DEMAND TO PAY; ASSESSMENT REMAINS VALID. A valid assessment must constitute a written notice and demand for a definite tax liability and must indicate a clear due date for payment, because the demand signals when penalties and interest accrue and informs the taxpayer of its remedies. Applying these principles, the CTA held that the FLD and FAN contained an unequivocal demand despite using the phrase “you are requested to pay,” since a demand may properly take the form of a request for payment; here, the FAN stated a definite amount and expressly provided June 30, 2022 as the payment deadline. Moreover, the title “Formal Letter of Demand” itself indicated the CIR’s intention to demand payment, and the phrases “you are requested to pay” and “if you are amenable” did not negate the demand. Thus, the assessment notices validly demanded payment of the deficiency taxes. (Marina Square Properties, Inc. v. CIR, CTA Case No. 11092, June 29, 2026)

3-YEAR PRESCRIPTIVE PERIOD WAS EXTENDED BY 420 DAYS DUE TO COVID-19  PANDEMIC. Internal revenue taxes must generally be assessed within 3 years from the last day prescribed for filing the return or the actual filing date, whichever is later, subject to the suspension provisions; during the COVID-19 pandemic, various legislations/regulations validly suspended the running of the prescriptive period during the specified ECQ/MECQ period. Applying these rules, although the original 3-year periods for 2018 income tax, VAT, WTC, and EWT liabilities had generally expired before the FLD was issued, the CTA held that the applicable COVID-19 suspensions validly extended the prescriptive periods by 420 days; consequently, the BIR’s right to assess remained timely for all the deficiency taxes involved, before the FLD was issued and received (Marina Square Properties, Inc. v. CIR, CTA Case No. 11092, June 29, 2026)

TAXPAYER WAS NOT LIABLE FOR 30% RCIT ON PAGCOR’S USE OF THE CORPORATE OFFICES BECAUSE THE LEASE EXPRESSLY PROVIDED THAT SUCH USE WAS WITHOUT ADDITIONAL RENT. Income derived from taxable activities is subject to regular corporate income tax, while the tax treatment of PAGCOR-related income depends on the nature of the income actually earned; the CIR treated rental income from PAGCOR as subject to 30% RCIT on the theory that the reported rent supposedly covered both the gaming area and the corporate offices, with only the former being connected to exempt gaming activities. The CTA, however, found no factual or contractual basis for imputing rental income to the corporate offices because the Lease Agreement expressly provided that the rent pertained to the gaming premises, and that, upon payment of the stipulated rent, PAGCOR could continue using the Office Premises “without any further charge or payment therefor.” Thus, the taxpayer actually derived rental income only from the gaming premises and did not earn any additional rental income from PAGCOR’s use of the corporate offices. (Marina Square Properties, Inc. v. CIR, CTA Case No. 11092, June 29, 2026)

DISALLOWANCE OF MCIT CARRY-OVER WITHOUT EXPLANATION IS VOID. An assessment is void unless the taxpayer is informed in writing of the factual and legal bases thereof, as this is a substantive and mandatory requirement. Here, the FLD deducted the MCIT and income tax carried over to 2019 from the taxpayer’s total tax credits/payments, effectively disallowing these amounts, but failed to explain the factual and legal basis for their disallowance; thus, the taxpayer was not adequately informed of why these tax credits were rejected, rendering the corresponding assessment items void. (Marina Square Properties, Inc. v. CIR, CTA Case No. 11092, June 29, 2026)

INTEREST INCOME FROM A LOAN BY REAL ESTATE BUSINESS IS NOT SUBJECT TO VAT; BIR MUST PROVE INTEREST INCOME’S CONNECTION TO THE MAIN BUSINESS. VAT applies to services rendered in the course of trade or business, including transactions incidental thereto, but a transaction may be considered incidental only when there is an intimate connection between it and the taxpayer’s main business activity; moreover, interest income from loans is generally subject to VAT when earned by a lending investor, dealer in securities, financial institution, or an entity performing similar financing activities. Here, the taxpayer was principally engaged in the purchase, development, leasing, management, and sale of real and personal properties, and was not a lending investor, dealer in securities, or financial institution; although the interest income from its loan could potentially be VATable if the loan transaction were incidental to its business, the BIR failed to establish any clear relation or intimate connection between the loan and taxpayer’s main real estate business, merely stating that the income was not among its exempt activities. Thus, absent proof that the loan was incidental to petitioner’s VATable business, the interest income was not subject to VAT. (Marina Square Properties, Inc. v. CIR, CTA Case No. 11092, June 29, 2026)

PROCEEDS FROM DISPOSAL OF PROPERTY BY PAGCOR CONTRACTEE ENGAGED IN REAL ESTATE IS SUBJECT TO VAT. The tax exemption extended to PAGCOR contractees applies only to earnings derived from casino/gaming operations conducted under the PAGCOR franchise, while income from other activities remains subject to tax; likewise, transactions incidental to a taxpayer’s main business may be subject to VAT under the NIRC. Here, although the  proceeds from the disposal of property and equipment involved equipment previously used in casino operations, and the sale itself did not constitute earnings derived from PAGCOR’s gaming operations the disposal was considered a transaction incidental to petitioner’s business of purchasing, leasing, and selling real and personal properties, making the proceeds subject to VAT. (Marina Square Properties, Inc. v. CIR, CTA Case No. 11092, June 29, 2026)

RENTAL INCOME FROM PAGCOR’S USE OF CORPORATE OFFICE IS NOT SUBJECT TO VAT IF LEASE AGREEMENT PROVIDES THAT PAGCOR WILL NOT PAY RENT FOR THE USE THEREOF. Under the PAGCOR Charter and the Lease Agreement between the taxpayer and PAGCOR, only actual or constructively received rent income may be subjected to VAT. Here, rental income was based on the assumption that a portion of PAGCOR’s rent payments pertained to its use of the corporate offices, allegedly outside the exempt gaming activities; however, the lease agreement expressly provided that PAGCOR would incur no charge or further payment for its use of the Office Premises, resulting in no actual or constructive receipt of rent income by petitioner. Thus, there was no VATable rental income arising from PAGCOR’s use of the corporate offices, and the VAT assessment was cancelled. (Marina Square Properties, Inc. v. CIR, CTA Case No. 11092, June 29, 2026)

DISALLOWANCE OF INPUT VAT CARRY-OVER WITHOUT EXPLANATION IS VOID. An assessment or disallowance is void when the taxpayer is not informed in writing of the factual and legal bases thereof. Here, the BIR deducted input tax carried over to 2019 from the computed VAT due, effectively disallowing the amount and increasing the basic deficiency VAT, but neither the FLD nor the Details of Discrepancies stated the factual or legal basis for such disallowance. Accordingly, the disallowance of input tax carry-over was void, and after allowing the input tax credits, the taxpayer’s credits were sufficient to cover its output VAT for CY 2018, resulting in no basic deficiency VAT liability. (Marina Square Properties, Inc. v. CIR, CTA Case No. 11092, June 29, 2026)

BIR CANNOT VALIDLY ASSESS TAXPAYER FOR FAILURE TO REFUND EXCESS WITHHOLDING TAX TO EMPLOYEES; BIR’S ASSESSMENT BASED ON MERE COMPARISON OF ALPHALIST AND AFS WITHOUT EXAMINING THE NATURE OF THE ACCOUNTS IS VOID. The penalty imposed on an employer or withholding agent applies when it fails or refuses to refund excess withholding tax to an employee, and does not provide a basis for assessing additional withholding tax merely from discrepancies in compensation expenses. Here, the BIR assessed deficiency WTC based on a discrepancy between compensation expenses reflected in taxpayer’s AFS and amounts reported in its Alphalist/BIR Form 1601-C, but its reliance on Section 252 was misplaced because that provision concerns the non-refund of excess withholding tax, whereas the assessment sought to impose additional withholding tax. The assessment also lacked sufficient factual basis because the amount taken from the Alphalist included non-taxable compensation, yet the BIR simply compared this amount with selected salary and payroll-related accounts in the AFS and treated the entire difference as compensation subject to WTC without examining the nature and taxability of the individual accounts. Thus, the BIR failed to establish both the legal authority and factual basis for the assessment, rendering the deficiency WTC assessment devoid of merit and subject to cancellation. (Marina Square Properties, Inc. v. CIR, CTA Case No. 11092, June 29, 2026)

BIR’S EWT ASSESSMENT BASED ON MERE COMPARISON OF BOOKS/AFS AND WITHHOLDING TAX RETURN IS VOID; BIR MUST IDENTIFY THE SPECIFIC TRANSACTIONS AND NATURE OF INCOME PAYMENTS. An assessment must inform the taxpayer in writing of the specific factual and legal bases upon which it is made; otherwise, the assessment is void for failure to satisfy the statutory and constitutional requirements of due process. Here, the BIR assessed deficiency EWT based on discrepancies between the taxpayer’s expenses per books/AFS and its BIR Form 1601-E returns, classifying the alleged discrepancies as purchases of goods, purchases of services, rent, and professional fees and applying different EWT rates. However, the BIR merely invoked Section 57(B) of the NIRC and Section 2.57.2 of RR No. 2-98 without identifying the specific transactions covered, the nature of the income payments, the identities or classes of payees, or the particular subsection of Section 2.57.2 that prescribed the applicable withholding rate. This was insufficient because Section 2.57.2 contains several subsections covering different types of income payments and payees, each with corresponding EWT rates; thus, a general reference to the provision did not enable the taxpayer to determine which transactions were allegedly subject to EWT, why they were taxable, and how the rates were applied. Accordingly, the deficiency EWT assessment was declared void for failure to sufficiently state its factual and legal bases. (Marina Square Properties, Inc. v. CIR, CTA Case No. 11092, June 29, 2026)

BIR’S DST ASSESSMENT (1) ON LOAN BASED ON YEAR-END BALANCE (2) PRIOR YEAR LEASE AND (3) RENT-FREE USE OF OFFICE IS VOID. DST is imposed on taxable debt instruments and certain lease agreements; however, a tax assessment must be supported by actual facts and transactions, rather than presumptions. Here, the BIR assessed deficiency DST by treating the year-end balances of taxpayer’s “Amounts owed by/to related party” accounts as loans or advances subject to DST. The Court found this improper because the amounts represented year-end balances, and the corresponding accounts already had substantial beginning balances, indicating that the amounts could have arisen from transactions in prior years. The BIR failed to determine whether the balances represented new loans or advances actually made during the year and did not present supporting documents, such as instructional letters, memoranda, vouchers, or other evidence establishing the existence of taxable loan transactions. The Court stressed that assessments cannot rest on reasonable or logical presumptions but must be grounded on actual facts. The DST assessments on the parking-area lease income and rental expense involving, respectively, were likewise improper because the relevant lease agreements were executed in prior years. Finally, the DST on alleged rent income was unfounded because the taxpayer did not receive any additional rent for PAGCOR’s use of the Office Premises, while the PAGCOR Gaming Premises lease was executed in prior year and was exempt from DST under the PAGCOR Charter. Accordingly, the BIR failed to establish that the assessed transactions were taxable DST transactions occurring within the audit period, and the entire deficiency DST assessment was cancelled. (Marina Square Properties, Inc. v. CIR, CTA Case No. 11092, June 29, 2026)

BIR’S FAILURE TO ADDRESS TAXPAYER’S ARGUMENTS IN THE PAN RENDERS THE ASSESSMENT VOID. The Tax Code requires that the taxpayer be informed in writing of the factual and legal bases of the assessment and that its defenses and supporting evidence be meaningfully considered; otherwise, the assessment is void for violation of administrative due process. The Supreme Court held that due process requires not merely an opportunity to be heard but also that the BIR actually consider and address the taxpayer’s explanations, with reasons stated for rejecting them. Here, the taxpayer filed a reply to the PAN, raising factual and legal arguments against the proposed assessment, but the subsequent FAN/ANs neither acknowledged nor addressed taxpayer’s arguments and were substantially identical to the PAN, except for the computation of interest. The subsequent protest against the FAN/ANs did not cure the defect because the denial of due process had already occurred at the assessment stage. Accordingly, the FAN/ANs were null and void, and the assessment and subsequent decision were cancelled and set aside. [(Ammex I-Support Corporation v. CIR, CTA Case No. 11192, April 17, 2026; Abraham Holdings, Inc.(Formerly Armadillo Holdings, Inc.) v. CIR, CTA Case No. 11088, June 8, 2026; Ozamiz City v. CIR, CTA Case No. 10828, June 18, 2026; CIR v. Marina Square Properties, Inc., CTA EB No. 3051, CTA Case No. 13049, May 21, 2026; Konica Minolta Marketing Services (Philippines) Inc., v.

3-YEAR ASSESSMENT PERIOD APPLIES IF BIR FAILS TO PROVE FRAUDULENT INTENT. The extended prescriptive period applies only in cases of a false or fraudulent return with intent to evade tax or failure to file, while absent fraud or intentional falsity, the applicable period to collect an assessed tax is 3 years from the assessment. Here, the BIR failed to establish that taxpayer deliberately falsified her returns or intended to evade taxes; rather, she filed her AITRs, voluntarily paid income taxes, and reasonably relied on the BIR Form 2316 and tax withholdings of her employer, the Supreme Court, as statutory withholding agent. Thus, the alleged errors did not constitute fraud, making the extended prescriptive period inapplicable. (CIR v. Justice Maria Lourdes P.A. Sereno, CTA EB No. 2996, CTA Case No. 10792, April 23, 2026)

COOPERATIVE’S TAX EXEMPTION RETROACTS TO THE DATE OF ITS REGISTRATION. For cooperatives, while the law provides that tax exemption generally takes effect upon issuance of the Certificate of Tax Exemption, the initial issuance of such certificate is retroactive to the date the law took effect, provided that the cooperative was registered with the Cooperative Development Authority (CDA). Here, the taxpayer was registered with the CDA in 2009, and its Certificate of Tax Exemption issued in 2012 was its first certificate; hence, the certificate’s effectivity retroacted to 2009, making taxpayer exempt from income tax and VAT beginning taxable year 2009 despite the certificate being issued only in 2012. Thus, the taxpayer was not liable for the deficiency taxes assessed for TY 2009, CIR v. Serbiz Multi-Purpose Cooperative, CTA EB No. 3057, (CTA Case No. 10369) May 28, 2026)]

RECEIPT OF THE FORMAL LETTER OF DEMAND/FINAL ASSESSMENT NOTICE (FLD/FAN) PRIOR TO EXPIRATION OF 15-DAY PERIOD TO REPLY TO THE PAN RENDERS THE ASSESSMENT VOID. A taxpayer must be given 15 days from receipt of the PAN to submit a reply, and the BIR must wait for the taxpayer’s response or the lapse of the 15-day period before issuing the FLD/FAN; here, the taxpayer received the PAN on January 4, 2013, as shown by the notation on the PAN itself, giving it until January 21, 2013 to respond because the 15th day fell on a Saturday. However, the BIR issued the FAN on January 14, 2013, seven days before the expiration of the response period, thereby prematurely terminating respondent’s statutory opportunity to contest the PAN. The BIR’s unsupported claim that the PAN was served on December 28, 2012 was insufficient, as it presented no proof of service, while the PAN itself indicated receipt on January 4, 2013. The subsequent filing of a protest and administrative appeal did not cure the defect. [CIR v. Kuehne + Nagel, Inc., CTA EB No. 3024 (CTA Case No. 10216), April 15, 2026]

TAXPAYER CANNOT REFUND AN ERRONEOUSLY PAID IN A TAX ASSESSMENT CASE. SEE DISSENTING OPINION. A taxpayer seeking a refund or tax credit of erroneously or illegally collected taxes must first file a written administrative claim with the CIR, and both the administrative and judicial claims must be filed within two years from the date of payment; this two-year period is mandatory and jurisdictional. Here, the taxpayer paid tax during the reinvestigation of its TY 2009 assessment. Although the Court in Division subsequently found that the payments were made pursuant to a void assessment and ordered their refund, the Court En Banc held that the CTA had no jurisdiction to grant such relief. Moreover, with respect to all the payments, the taxpayer failed to file a written claim for refund or tax credit with the CIR within two years and did not even allege or pray for a refund in its Petition for Review. Accordingly, the En Banc modified the Division’s decision by deleting the refund/TCC while affirming that the assessments were void. Dissenting Opinion: The CTA has jurisdiction not only over disputed assessments and refund cases, but also over “other matters arising under the NIRC” or laws administered by the BIR. Moreover, it may resolve related issues necessary for the complete and orderly disposition of the case. Lastly, the period should be relaxed because of the peculiar circumstances of the case. Strict procedural rules should not be applied where they would allow the government to retain taxes it had no legal right to collect. [CIR v. Kuehne + Nagel, Inc., CTA EB No. 3024 (CTA Case No. 10216), April 15, 2026]

A SUBSEQUENT LOA IS VOID IF IT COVERS A PERIOD UNDER AN EARLIER LOA, WHICH HAS BEEN FULLY SETTLED. For income tax purposes, the examination and inspection of a taxpayer’s books shall be conducted only once in a taxable year, subject to limited exceptions, while the BIR regulations provide a “One LOA per Taxable Year” rule by generally allowing only one LOA for the same taxpayer, tax type, and period, except when a subsequent LOA is justified by circumstances such as the reassignment, retirement, or inability of the originally assigned revenue officers to continue the investigation. Applying these rules, the third LOA was infirm because it substantially overlapped with the period already examined under the First and Second LOAs. Moreover, none of the recognized exceptions justified the third LOA: even the alleged fraud, irregularity, or mistake had already been investigated under the Second LOA, and the alleged undeclared gain from the sale of land and improvements – which became the basis for the ad valorem penalties under the third LOA – had already been considered and ultimately abandoned in the FDDA issued under the Second LOA. More importantly, the assessments under the second LOA had already become final and were fully settled when taxpayer voluntarily paid the assessed deficiency taxes. thereby closing the audit and assessment process. Thus, the Third LOA improperly attempted to reopen and reassess matters that had already been examined, resolved, abandoned, and paid, in violation of the “One LOA per Taxable Year” rule and the principles of finality of assessments and orderly tax administration; consequently, the third LOA was void, and all assessments issued pursuant thereto were likewise void and without legal effect. [Orica Nitrates Philippines, Inc. v. CIR, CTA Case No. 10946, (April 15, 2026)]

BIR’S FAILURE TO INDICATE THE DUE DATE IN THE FAN RENDERS THE ASSESSMENT VOID. The Tax Code mandates that the taxpayer be informed in writing of the facts and law upon which an assessment is based, and jurisprudence establishes that a valid formal assessment must contain not only the computation of the tax liability but also a definite demand for payment within a prescribed period. A FAN that fails to state a definite due date is not a valid assessment because the due date determines when the taxpayer must pay, when penalties and interest may accrue, and allows the taxpayer to determine and exercise the proper remedies. Here, the FLD dated merely instructed taxpayer to pay the ad valorem penalties “within the time shown in the assessment notice,” but the FAN itself contained no due date, with the corresponding field left blank. Thus, there was no date certain or specific period within which petitioner was required to pay, resulting in the absence of a valid demand for payment. (Orica Nitrates Philippines, Inc. v. CIR, CTA Case No. 10946, April 15, 2026)

FLD/FAN ISSUED 10-DAYS AFTER THE RECEIPT OF THE PAN RENDERS THE ASSESSMENT VOID. The Tax Code requires the BIR to issue a PAN informing the taxpayer of the facts and law supporting the proposed deficiency assessment and to give the taxpayer 15 days from receipt of the PAN to respond before the FLD/FAN may be validly issued; these requirements are substantive due process safeguards, and failure to strictly comply renders the assessment void. In this case, the BIR issued the PAN but issued the FLD/FAN only 10 days later, without waiting for the full 15-day period, thereby depriving the taxpayer of the opportunity to contest the PAN and present supporting evidence. Accordingly, the FLD/FAN and the resulting deficiency tax assessment were declared void and without effect, and the assessments were cancelled and set aside.

Revenue Memorandum Circular No. 96-2026

The BIR clarifies the qualification of Export-Oriented Enterprises (EOE) to VAT Refund during the transitory period for securing a VAT Zero-Rating Certificate from the Export Marketing Bureau of the Department of Trade and Industry (EMB-DTI).
