The Supreme Court has ruled that the Bureau of Internal Revenue (BIR) must strictly adhere to the procedures outlined in Revenue Memorandum Order (RMO) No. 20-90 when assessing taxes. Failure to comply with these procedures, particularly regarding the execution and acceptance of waivers extending the prescriptive period for assessment, renders the assessment invalid. This decision underscores the importance of protecting taxpayers from prolonged uncertainty and ensuring that the government promptly and properly assesses internal revenue taxes.

Taxing Time: When Waivers Extend the Assessment Deadline

This case revolves around the validity of an assessment notice issued by the BIR against FMF Development Corporation (FMF) for deficiency income and withholding taxes for the taxable year 1995. FMF filed its Corporate Annual Income Tax Return for 1995 and later an amended return. The BIR, finding discrepancies, issued pre-assessment notices to FMF. In response, FMF contested these notices and requested a reinvestigation. Subsequently, FMF executed a waiver of the three-year prescriptive period, seemingly extending the BIR’s assessment period. However, FMF later argued that this waiver was invalid, and therefore, the assessment was time-barred.

The critical issue before the Court was whether the waiver executed by FMF validly extended the BIR’s assessment period. Under Section 203 of the National Internal Revenue Code (NIRC), the BIR has three years from the filing of the tax return to assess internal revenue taxes. An exception exists in Section 222(b) of the NIRC, which allows the Commissioner and the taxpayer to agree in writing to extend this assessment period. However, this extension requires strict adherence to specific procedures.

(b) If before the expiration of the time prescribed in Section 203 for the assessment of the tax, both the Commissioner and the taxpayer have agreed in writing to its assessment after such time, the tax may be assessed within the period agreed upon. The period so agreed upon may be extended by subsequent written agreement made before the expiration of the period previously agreed upon.

The BIR argued that the waiver was valid because it complied with Section 222(b) of the NIRC, asserting it was in writing, signed by the taxpayer and the Commissioner, and executed within the three-year period. They further contended that the requirements in RMO No. 20-90 are merely directory. FMF, however, countered that the waiver was void due to non-compliance with RMO No. 20-90, specifically citing that the Commissioner did not sign it, the date of acceptance was missing, and they were not furnished a copy of the BIR-accepted waiver. These arguments highlighted a disagreement on the validity and implications of the waiver.

The Court sided with FMF, emphasizing the need for strict compliance with RMO No. 20-90 when executing waivers. RMO No. 20-90 outlines specific requirements for waivers, including proper execution, acceptance by the BIR, and documentation. The Court found the waiver in question to be defective because it wasn’t proven that FMF received a copy of the BIR-accepted waiver, the Commissioner’s signature was absent, and it lacked the acceptance date, making it impossible to ascertain whether the waiver was accepted before the three-year period expired. Building on this, the Court reinforced the existing doctrine by declaring RMO No. 20-90 as mandatory.

The Supreme Court cited its ruling in Philippine Journalists, Inc. v. Commissioner of Internal Revenue, highlighting that waivers of the statute of limitations must be carefully and strictly construed. Waivers, being a derogation of the taxpayer’s right, should not be interpreted as an unequivocal relinquishment of the right to invoke prescription. In this case, the waiver became unlimited in time because it did not specify a definite date, agreed upon between the BIR and FMF, within which the former may assess and collect taxes.

Moreover, the Court rejected the BIR’s argument that the government cannot be estopped by the mistakes of its revenue officers in enforcing RMO No. 20-90. The law on prescription is designed to protect taxpayers, ensuring they are not subjected to prolonged uncertainty and unscrupulous tax investigations. Ultimately, the Court held that Assessment Notice No. 33-1-00487-95 was issued beyond the three-year prescriptive period and, therefore, was invalid.
