Mayon Motors, Inc. v. Acting Commissioner of Internal Revenue
REITERATIONFacts
The Antecedents: Petitioner Mayon Motors, Inc. imported seventeen (17) Pontiac automobiles in three separate shipments. The landed costs and advance sales taxes paid for each shipment were detailed. Specifically, two cars had a landed cost of P4,696.50 each, eleven cars had a landed cost of P4,870.76 each, and four cars had a landed cost of P5,060.60 each. Procedural History: Respondent Acting Commissioner of Internal Revenue assessed petitioner P35,353.22 as deficiency advance sales tax. Petitioner requested reconsideration, which was denied. The case was elevated to the Court of Tax Appeals (CTA), which modified the decision, ordering petitioner to pay P58,968.43 and denying petitioner's claim for refund of P17,272.60. The Petition: Petitioner appealed to the Supreme Court, questioning the interpretation of Sections 183(B), 184, and 185 of the National Internal Revenue Code concerning the computation of advance sales tax on imported automobiles.
Issue(s)
Whether the 'theoretical selling price' (landed cost plus mark-up) is the correct basis for determining the classification of an imported automobile under Section 184 or Section 185 of the National Internal Revenue Code (NIRC) for purposes of computing advance sales tax.
Ruling
The Supreme Court affirmed the decision of the Court of Tax Appeals, upholding the assessment of deficiency advance sales tax against petitioner Mayon Motors, Inc. The Court ruled that the landed cost plus the applicable mark-up represents the theoretical selling price for the purpose of computing the advance sales tax.
Ratio Decidendi
On Issue 1: The Supreme Court held that the methodology used by the Court of Tax Appeals (CTA) was correct because advance sales tax is designed to approximate the tax due on an original sale before that sale actually occurs. Under Section 183(B) of the National Internal Revenue Code (NIRC), the advance sales tax is calculated by adding a 'mark-up' (100%, 50%, or 25%) to the landed cost. To determine if a car is 'enumerated' in Section 184 (for cars with a selling price over P5,000) or Section 185 (for cars with a selling price of P5,000 or less), one must first calculate the theoretical selling price by adding the minimum mark-up to the landed cost. If this sum exceeds P5,000, the vehicle is classified under Section 184, which then mandates the application of the higher 100% mark-up rate to the landed cost. The Court emphasized that 'selling price' is not synonymous with 'landed cost' alone; the latter only accounts for the cost of importation, whereas the former naturally includes the importer's profit margin or mark-up. Furthermore, the Court rejected the petitioner's reliance on congressional debates, citing Song Kit Chocolate Factory v. Central Bank to rule that a legislator's individual opinion is not binding on judicial interpretation. Ultimately, the transition from Republic Act No. 253 to Republic Act No. 594 made advance sales tax final and not subject to subsequent credit, confirming that the landed cost plus mark-up must theoretically represent the final selling price to the public.
Main Doctrine
The advance sales tax on imported articles is computed based on the landed cost plus the applicable mark-up, which theoretically represents the selling price. The determination of the correct mark-up (100% or 50%) depends on whether the automobile's theoretical selling price falls under Section 184 or Section 185 of the National Internal Revenue Code.
