In Commissioner of Internal Revenue v. United Salvage and Towage (Phils.), Inc., the Supreme Court addressed the necessity of formally offering evidence in tax court proceedings and the requisites for a valid tax assessment. The Court ruled that the Court of Tax Appeals (CTA), while not strictly bound by technical rules of evidence, requires the formal offer of evidence for it to be considered. The Supreme Court also emphasized that tax assessments must clearly state the factual and legal bases for the deficiency, ensuring taxpayers are adequately informed of their obligations and can properly contest the assessment.

Unveiling Tax Liabilities: When Assessments Lack Foundation

United Salvage and Towage (Phils.), Inc. (USTP), a subcontractor for petroleum operations, faced deficiency tax assessments from the Commissioner of Internal Revenue (CIR) for the taxable years 1992, 1994, 1997, and 1998. These assessments covered income tax, withholding tax, value-added tax (VAT), and documentary stamp tax (DST). USTP contested these assessments, arguing that the notices lacked the necessary factual and legal basis. The core legal question revolved around whether the CIR had properly presented evidence to support its claims and whether the tax assessments met the due process requirements of informing the taxpayer of the grounds for the assessment.

The Court of Tax Appeals (CTA) Special First Division initially ruled in favor of USTP, canceling the deficiency assessments for Expanded Withholding Tax (EWT) and Withholding Tax on Compensation (WTC) for 1992, noting the petitioner’s failure to formally offer Preliminary Assessment Notices (PANs) for taxable years 1994 and 1998 as evidence. Moreover, the CTA found that the Final Assessment Notices (FANs) for EWT in 1994 and 1998 lacked the requisite factual and legal bases, rendering them void under Section 228 of the 1997 National Internal Revenue Code (Tax Code). The CTA En Banc affirmed this decision with a modification, upholding only the 1998 EWT assessment. This ruling prompted the CIR to elevate the case to the Supreme Court, questioning the CTA’s adherence to technical rules of evidence and the validity of the tax assessments.

The Supreme Court began its analysis by addressing the role of the Court of Tax Appeals (CTA) and the rules of evidence that govern its proceedings. While Section 8 of Republic Act No. 1125 grants the CTA the power to promulgate its own rules and states that its proceedings are not strictly governed by technical rules of evidence, the Court emphasized that the formal offering of evidence remains a critical requirement. The Court cited Section 34, Rule 132 of the Revised Rules on Evidence, which explicitly states that courts shall consider only evidence that has been formally offered. This principle ensures that all parties have the opportunity to examine and object to the admissibility of evidence, facilitating a fair and transparent legal process.

Acknowledging prior instances where the rule on formal offer of evidence had been relaxed, the Court reiterated that such exceptions are applied with extreme caution. In Vda. de Oñate v. Court of Appeals, the Supreme Court clarified that for evidence not formally offered to be admitted, it must have been duly identified by recorded testimony and incorporated into the case records. The CIR’s failure to formally offer the PANs for the 1994 and 1998 EWT assessments, without providing a justifiable reason, proved fatal to its case. The Court held that merely alluding to the existence of these documents during witness testimonies did not suffice, as no positive identification of the PANs was presented. As such, the Supreme Court agreed with the CTA En Banc that the PANs were not duly identified or incorporated into the case records, precluding their consideration as evidence.

Turning to the validity of the EWT assessment for 1994, the Supreme Court scrutinized whether it met the requirements of Section 228 of the Tax Code, which mandates that taxpayers be informed in writing of the law and facts on which an assessment is made. This provision is further elaborated in Revenue Regulation No. 12-99, which states that a formal letter of demand and assessment notice must specify the factual and legal bases of the assessment; otherwise, it is void. The Court found that the FAN for the 1994 EWT deficiency lacked the necessary details, providing only a tabulation of alleged deficiencies without explaining how the amount was derived or referencing the underlying transactions. This failure to provide adequate information violated the taxpayer’s right to due process.

The Supreme Court emphasized the mandatory nature of the requirements under Section 228 of the Tax Code and Revenue Regulation No. 12-99, highlighting that the use of the word “shall” indicates a strict obligation to inform the taxpayer of the assessment’s legal and factual foundations. Citing Commissioner of Internal Revenue v. Enron Subic Power Corporation, the Court reiterated that providing an advice of tax deficiency or a preliminary five-day letter does not substitute the mandatory written notice containing the legal and factual bases of the assessment. The Court underscored that any shortcuts in the prescribed content or process of assessment would not be tolerated, as they undermine the taxpayer’s ability to understand and contest the assessment.

Regarding the CIR’s argument that Revenue Regulation No. 12-99 was not yet operative when the PAN and FAN for 1994 were issued, the Supreme Court dismissed this claim, citing Commissioner of Internal Revenue v. Reyes. The Court clarified that tax regulations, being interpretive of a statute, generally have retroactive effect from the date the statute became effective. As Revenue Regulation No. 12-99 merely implements the law and does not create or take away vested rights, it was applicable to the 1994 assessment, which should have complied with its requirements. Therefore, the Supreme Court affirmed the CTA En Banc’s finding that the 1994 deficiency tax assessment disregarded Section 228 of the Tax Code and Revenue Regulation No. 12-99, rendering it legally ineffective.

Finally, the Supreme Court addressed the issue of prescription concerning the EWT for taxable year 1992, noting that the statute of limitations on assessment and collection of national internal revenue taxes was shortened from five (5) years to three (3) years under Batas Pambansa Blg. 700. The Court found that the FAN for the deficiency EWT and WTC for taxable year 1992 was issued on January 9, 1996, but the Preliminary Collection Letter was only issued on February 21, 2002, well beyond the three-year prescriptive period. The Court dismissed the CIR’s argument that USTP’s request for reinvestigation interrupted the prescriptive period, pointing out that the CIR only acted on the request on January 22, 2001, also beyond the three-year statute of limitations. Inaction by the CIR cannot prejudice the respondent.

Building on this principle, the Supreme Court cited Bank of the Philippine Islands v. Commissioner of Internal Revenue, emphasizing that a request for reinvestigation must first be granted or acted upon in due course before the suspension of the statute of limitations can take effect. In conclusion, the Supreme Court upheld the CTA En Banc’s decision, emphasizing that tax assessments must be grounded in law and fact, and that the government’s power to tax is not unlimited. The statute of limitations on tax collection protects taxpayers from prolonged uncertainty and ensures that the government acts diligently in pursuing tax claims.
