The Supreme Court ruled that a demand letter for tax deficiency assessments issued by a subordinate officer of the Bureau of Internal Revenue (BIR), acting on behalf of the Commissioner, is considered final and appealable to the Court of Tax Appeals (CTA). This means taxpayers must act on these demand letters within the prescribed period, even if not directly from the Commissioner, to preserve their right to appeal. Failure to do so renders the assessment final, executory, and demandable, impacting the taxpayer’s ability to contest the assessment.

Taxman’s Delegation: When Does a Demand Letter Trigger the Appeal Clock?

This case arose when Oceanic Wireless Network, Inc. challenged the authority of the Chief of the Accounts Receivable and Billing Division of the BIR National Office to issue final decisions on tax deficiency assessments. In 1988, Oceanic Wireless received deficiency tax assessments totaling P8,644,998.71 for the taxable year 1984. The company protested, seeking reconsideration or cancellation of the assessments. Subsequently, the Chief of the BIR Accounts Receivable and Billing Division denied the request for reinvestigation and reiterated the tax assessments in a letter dated January 24, 1991, demanding payment within ten days. When Oceanic Wireless failed to pay, warrants of distraint and levy were issued. This led Oceanic Wireless to file a Petition for Review with the CTA, contesting the warrants, which was ultimately dismissed for being filed beyond the 30-day period.

The CTA based its dismissal on the premise that the January 24, 1991 demand letter constituted the final decision of the Commissioner, triggering the 30-day appeal period. The core legal question was whether a demand letter issued by a subordinate officer, acting on behalf of the Commissioner, qualifies as a final decision appealable to the CTA. The Court of Appeals upheld the CTA’s decision, prompting Oceanic Wireless to elevate the matter to the Supreme Court.

The Supreme Court affirmed that a demand letter could indeed be considered a final decision on a disputed assessment, hinging on the language and tenor of the letter. The Court emphasized the necessity for the Commissioner of Internal Revenue to clearly communicate a final determination to the taxpayer, allowing them to understand when their right to appeal accrues. In this case, the letter unequivocally demanded payment of the deficiency taxes, with a warning of enforcement through distraint and levy upon failure to comply, coupled with a denial of the request for reconsideration due to lack of supporting documents.

. . . we deem it appropriate to state that the Commissioner of Internal Revenue should always indicate to the taxpayer in clear and unequivocal language whenever his action on an assessment questioned by a taxpayer constitutes his final determination on the disputed assessment, as contemplated by Sections 7 and 11 of Republic Act No. 1125, as amended. On the basis of his statement indubitably showing that the Commissioner’s communicated action is his final decision on the contested assessment, the aggrieved taxpayer would then be able to take recourse to the tax court at the opportune time.

The court then addressed the issue of delegation of authority. Under the National Internal Revenue Code (NIRC), the Commissioner can delegate powers to subordinate officials with the rank equivalent to a division chief or higher, except for specific powers enumerated in Section 7. These non-delegable powers include recommending the promulgation of rules and regulations, issuing rulings of first impression, compromising or abating tax deficiencies, and assigning internal revenue officers to establishments producing excise tax items. The act of issuing the demand letter did not fall under any of these exceptions.

Section 6 of the NIRC further clarifies that the authority to make tax assessments can be delegated. This means that an assessment made by a subordinate officer, if not reviewed or revised by the Commissioner, has the same force and effect as one issued by the Commissioner directly. Therefore, the demand letter issued by the Chief of the Accounts Receivable and Billing Division was deemed a valid exercise of delegated authority.

The Supreme Court highlighted that taxpayers have thirty days from receipt of a tax deficiency assessment to request a reconsideration; otherwise, the decision becomes final and demandable. Oceanic Wireless failed to bring the matter before the CTA within the prescribed period. While the exact date of receipt was not established, the Court applied the presumption of regular mail delivery under Section 2(v), Rule 131 of the Rules of Court. Given the filing date with the CTA, the assessment had long become final and executory, depriving the CTA of jurisdiction.
