Contractor's Tax Assessments: Prescription Periods and Gross Receipts Rules

The Supreme Court's 2000 decision in Protector's Services, Inc. v. Court of Appeals (G.R. No. 118176) clarifies important rules for businesses facing BIR assessments: the deadlines for protesting tax assessments are strict, the prescriptive period for assessment depends on when the final annual return is filed, and certain payments made on behalf of employees form part of a contractor's taxable gross receipts. The ruling offers practical guidance for taxpayers navigating the assessment and protest process.

The Facts of the Case

Protector's Services, Inc. (PSI), a security agency, was assessed deficiency percentage taxes for 1983, 1984, and 1985. The BIR sent demand letters by registered mail on December 7, 1987, which PSI claimed to have received on December 10, 1987—except for the 1985 assessment, which PSI denied receiving.

PSI protested the 1983 and 1984 assessments on January 12, 1988, but did not protest the 1985 assessment until July 22, 1988. The BIR denied the protests, and PSI appealed to the Court of Tax Appeals (CTA), which dismissed the case for lack of jurisdiction because the assessments had become final and unappealable. The Court of Appeals affirmed, and PSI elevated the matter to the Supreme Court.

The Issue

The central issues were: (1) whether the CTA had jurisdiction over PSI's appeal; (2) whether the assessments were made within the prescriptive period; (3) whether the period to collect the taxes had prescribed; and (4) whether the assessments were correct in including security guards' salaries in gross receipts.

The Ruling

Protest deadlines are mandatory. Under the National Internal Revenue Code provision on protesting assessments, a taxpayer must protest an assessment within 30 days from receipt; otherwise, the assessment becomes final and unappealable. PSI filed its protest 33 days after receiving the 1983 and 1984 assessments—three days late. The Court held that the CTA correctly dismissed the appeal for lack of jurisdiction. For the 1985 assessment, the Court applied the legal presumption that a properly addressed, prepaid letter mailed by registered mail was received in the ordinary course of mail. PSI's denial of receipt did not overcome this presumption.

Prescription periods run from the final annual return. Under Batas Pambansa Blg. 700, which amended the National Internal Revenue Code provisions on limitation of assessment and collection, the prescriptive period for assessment is three years from the last day prescribed for filing the return—but only for taxable years beginning 1984. For 1983, the old five-year period applied. The Court also held, citing Commissioner of Internal Revenue v. Court of Appeals (G.R. No. 115712), that the prescriptive period for contractor's tax is computed from the filing of the final annual percentage tax return, not from the tentative quarterly payments.

Pending appeals suspend the collection period. Under the National Internal Revenue Code provision on suspension of the running of the statute of limitations, the period for collection is suspended when the taxpayer is prohibited from being collected from—including during the pendency of an appeal before the CTA and the Supreme Court. Citing Republic v. Ker and Company, Ltd., the Court reasoned that allowing the prescriptive period to run during appeals would encourage taxpayers to delay payment in hopes of avoiding taxes.

Security guards' salaries are part of gross receipts. The Court upheld the BIR's position that salaries paid to security guards, including the employer's share of SSS, SIF, and Medicare contributions, form part of the agency's taxable gross receipts for contractor's tax purposes. The guards are employees of the agency, not the clients, so these amounts are not deductible from gross receipts. The Court gave weight to BIR rulings on this point, noting that rulings of government officials implementing tax laws command respect.

Practical Takeaways

• Act fast on BIR assessments. The 30-day protest period is strictly enforced. Missing it by even a few days makes the assessment final and unappealable—and removes the CTA's jurisdiction to hear an appeal.
• Keep proof of mailing and receipt. The legal presumption of receipt for registered mail is strong. A taxpayer's bare denial of receipt, especially when the assessment involves a substantial amount, will rarely overcome it.
• Know which prescriptive period applies. For taxable years before 1984, the five-year assessment period applies; for 1984 onward, it is three years. The period runs from the filing of the final annual return, not from quarterly payments.
• Appeals suspend the collection clock. Filing a case before the CTA or the Supreme Court stops the running of the prescriptive period for collection. This prevents taxpayers from using appeals to run out the clock on tax liabilities.
• Employee-related payments count as gross receipts. For security agencies and similar contractors, salaries and employer contributions paid for employees are not deductible from gross receipts for percentage tax purposes.
