GR 205045; (January, 2017) (Digest)
G.R. No. 205045 & 205723, January 25, 2017
Commissioner of Internal Revenue vs. San Miguel Corporation
FACTS
San Miguel Corporation (SMC) sought to register “San Mig Light” as a new brand of beer in 1999, which was approved by the Bureau of Internal Revenue (BIR). SMC subsequently paid excise tax at the lower rate applicable to new brands. In 2002, however, the BIR issued a Notice of Discrepancy, reclassifying “San Mig Light” as a variant of SMC’s existing “San Miguel Pale Pilsen” and thus subject to a higher excise tax rate. The BIR demanded deficiency excise tax payments exceeding ₱800 million. SMC protested, arguing that “San Mig Light” had distinct packaging, alcohol content, and a low-calorie formulation, making it a new brand. The BIR maintained its position, leading to the issuance of a Formal Assessment Notice.
SMC filed petitions for review with the Court of Tax Appeals (CTA), seeking the cancellation of the assessments and claiming a refund for taxes paid under protest. The CTA ruled in favor of SMC, holding that “San Mig Light” was a new brand. The CTA En Banc affirmed these decisions. The Commissioner of Internal Revenue elevated the case to the Supreme Court, arguing that the CTA erred in its classification and that the BIR had the authority to reclassify the product.
ISSUE
Whether the BIR correctly classified “San Mig Light” as a variant of an existing brand, subject to a higher excise tax, and whether the BIR’s reclassification through a Notice of Discrepancy was valid.
RULING
The Supreme Court denied the petitions and affirmed the CTA’s rulings. The Court held that “San Mig Light” was a new brand, not a variant. The legal logic centered on the statutory definition under Section 143 of the National Internal Revenue Code. A “variant” refers to a brand differentiated merely by packaging or volume, not by a fundamental change in product characteristics. The Court found that “San Mig Light” possessed distinct and substantive differences from “San Miguel Pale Pilsen,” including its low-calorie formulation, different alcohol content, and unique market positioning, which took it beyond mere packaging changes.
Crucially, the Court ruled that the BIR’s reclassification via a Notice of Discrepancy was an invalid, quasi-legislative act that amended revenue regulations without following the required public notice and hearing. The power to define and classify items for excise tax purposes is a legislative function. The BIR’s action effectively imposed a new tax liability retroactively, violating the principles of due process. Furthermore, the Court emphasized that SMC secured a prior ruling from the BIR classifying the product as a new brand, and it relied on this ruling in good faith. The BIR was thus estopped from arbitrarily reversing its own determination to SMC’s detriment.
