G.R. No. 159694 & 163581; January 27, 2006
COMMISSIONER OF INTERNAL REVENUE, Petitioner, vs. AZUCENA T. REYES, Respondent. (Consolidated with AZUCENA T. REYES, Petitioner, vs. COMMISSIONER OF INTERNAL REVENUE, Respondent.)

FACTS

Maria C. Tancinco died in 1993. Based on a sworn information, the BIR investigated her estate and issued a final estate tax assessment of approximately P14.9 million against her heirs, including respondent Azucena T. Reyes, in May 1998. The heirs protested, claiming the property had been sold before death. The Commissioner of Internal Revenue (CIR) rejected the protest and initiated collection via a warrant of distraint and levy, scheduling a public auction of the estate property.
Reyes filed a Petition for Review with the Court of Tax Appeals (CTA), which issued an injunction halting the auction. During the CTA proceedings, Reyes applied for a compromise settlement under new BIR regulations, offering to pay a portion of the basic tax. The CIR rejected the offer. The CTA later dismissed Reyes’s petition, ruling it was filed out of time and that the assessment had become final. The Court of Appeals reversed the CTA, annulling its decision and remanding the case for action on the compromise application, prompting both parties to elevate the matter to the Supreme Court.

ISSUE

The core issue is whether the estate tax assessment issued by the BIR against the estate of Maria C. Tancinco is valid.

RULING

The Supreme Court ruled the assessment was void. The legal logic hinges on due process and statutory compliance. Section 228 of the 1997 Tax Code mandates that a taxpayer must be informed in writing of the factual and legal bases of an assessment. This requirement is fundamental; an assessment that fails to state these bases is invalid. The Court found the BIR’s preliminary and final assessment notices against the estate were generic, merely stating a computed deficiency. They did not explain how the valuation was reached or cite the specific legal provisions applied.
Consequently, the void assessment could not attain finality, rendering moot the issues of the timeliness of Reyes’s protest and petition. A void assessment produces no legal effects. It cannot be a valid subject of a compromise, nor can it justify collection through levy and auction. The Court emphasized that the right to be informed of the basis of a government claim is a cornerstone of due process, especially in taxation where the power is far-reaching. The CTA therefore retained jurisdiction to rule on the assessment’s validity. The Supreme Court affirmed the Court of Appeals’ annulment of the CTA decision but modified it by declaring the assessment void, without prejudice to the BIR issuing a proper, valid assessment in accordance with the law.
