G.R. No. 134062 ; April 17, 2007
COMMISSIONER OF INTERNAL REVENUE, Petitioner, vs. BANK OF THE PHILIPPINE ISLANDS, Respondent.

FACTS

The Commissioner of Internal Revenue (CIR) issued two notices dated October 28, 1988, assessing the Bank of the Philippine Islands (BPI) for deficiency percentage and documentary stamp taxes for 1986, totaling approximately ₱129.5 million. The notices, using a standard BIR form, merely stated the computed amounts due, including surcharges and interest, but did not provide any explanation of the legal or factual bases for the assessments. BPI, through counsel, replied on December 10, 1988, contesting the validity of the notices for failing to inform the taxpayer of the reasons for the assessment, thereby preventing an intelligent decision to pay or protest. The CIR did not immediately respond.
On June 27, 1991, BPI received a CIR letter dated May 8, 1991, which, while characterizing BPI’s prior letter as an invalid protest, proceeded to explain the bases for the assessments and stated it was the final decision. BPI requested reconsideration on July 6, 1991, which was denied in a letter received on January 21, 1992. BPI filed a petition for review with the Court of Tax Appeals (CTA) on February 18, 1992. The CTA dismissed the case, ruling the 1988 assessments had become final due to BPI’s failure to file a valid protest. The Court of Appeals reversed, holding the 1988 notices were invalid assessments, making the 1991 letter the operative assessment and BPI’s petition timely.

ISSUE

Whether the notices of assessment dated October 28, 1988, were valid, thereby making BPI’s petition to the CTA filed on February 18, 1992, untimely.

RULING

The Supreme Court affirmed the Court of Appeals, ruling the October 28, 1988 notices were not valid assessments. The legal logic is anchored on the fundamental requirement of due process in tax administration. Under the then Section 270 of the National Internal Revenue Code, the CIR must first notify the taxpayer of his findings before issuing a formal assessment. The Court held that for a notice to be valid and to trigger the taxpayer’s obligation to protest, it must inform the taxpayer in clear terms of the legal and factual bases of the assessment. This allows the taxpayer to understand the liability, make an informed decision, and effectively exercise the right to contest.
The 1988 notices were mere computations without any explanation. They failed to state what specific percentage tax was involved or the issues regarding the documentary stamp tax. Consequently, they were void and produced no legal effect. The valid assessment was the May 8, 1991 letter, which for the first time explained the bases. BPI’s subsequent request for reconsideration and eventual petition to the CTA were filed within the statutory periods. Therefore, the CTA had jurisdiction, and the case was remanded for a resolution on the merits of the tax liabilities. The Court emphasized that the government’s power to tax must be exercised fairly and not arbitrarily, ensuring taxpayers are accorded due process.
