G.R. No. L-25289. June 28, 1974.
SURIGAO ELECTRIC CO., INC., petitioner, vs. THE HONORABLE COURT OF TAX APPEALS and COMMISSIONER OF INTERNAL REVENUE, respondents.

FACTS

Petitioner Surigao Electric Co., Inc., a legislative franchise grantee, received a warrant of distraint and levy in November 1961 for a deficiency franchise tax attributed to “Mainit Electric.” The petitioner contested this, asserting it held no franchise for Mainit. The Commissioner of Internal Revenue, by letter dated April 2, 1962, referred the matter to the General Auditing Office, which had previously issued a 4th Indorsement finding the petitioner liable for a deficiency tax of P21,156.06. In a letter dated August 2, 1962, the petitioner sought reconsideration from the Auditor General, admitting liability only at the 2% rate specified in its franchise, not the 5% rate applied under the Tax Code.
Following an exchange of correspondence, the Commissioner issued a revised assessment dated April 29, 1963 (received May 8, 1963), demanding P11,533.53 for deficiency tax and surcharges for the period April 1956 to June 1959. The petitioner requested a recomputation on June 6, 1963. The Commissioner denied this request by letter dated June 28, 1963 (received July 16, 1963). The petitioner filed its appeal with the Court of Tax Appeals (CTA) on August 1, 1963. The CTA dismissed the appeal as time-barred, having been filed beyond the 30-day period prescribed by law.

ISSUE

Whether the petitioner’s appeal to the Court of Tax Appeals was filed within the statutory 30-day period.

RULING

No, the appeal was time-barred. The Supreme Court affirmed the CTA’s dismissal. The pivotal legal question was which communication from the Commissioner constituted the final, appealable decision. The Court held that the letter of demand dated April 29, 1963, received on May 8, 1963, was the definitive determination of the petitioner’s tax liability and thus the appealable ruling. This letter was the Commissioner’s final action on the petitioner’s prior protests, including its August 1962 letter disputing the tax rate. It contained a clear demand for payment and a warning of legal enforcement, indicating its finality.
The petitioner’s subsequent request for recomputation in June 1963 was deemed a mere reiteration of its original position without new substantive arguments. Counting the 30-day appeal period from the receipt of the June 28 denial letter, as the petitioner contended, would improperly allow a taxpayer to unilaterally delay the finality of an assessment by submitting pro forma requests. This would undermine the government’s imperative need for the prompt and certain collection of taxes, which are its lifeblood. Consequently, the 30-day period commenced on May 8, 1963, making the August 1, 1963 appeal filed well beyond the deadline.
