G.R. No. 159647. April 15, 2005.
COMMISSIONER OF INTERNAL REVENUE, Petitioner, vs. CENTRAL LUZON DRUG CORPORATION, Respondent.

FACTS

Respondent Central Luzon Drug Corporation, operating Mercury Drug stores, granted the 20% sales discount to senior citizens on medicine purchases in 1996, as mandated by Republic Act (RA) No. 7432. The total discount granted amounted to Php 904,769.00. For the taxable year 1996, however, the respondent corporation declared a net loss in its annual income tax return. It subsequently filed a claim for tax refund or credit for the total discount amount with the Bureau of Internal Revenue (BIR).
The Court of Tax Appeals (CTA) initially dismissed the claim, ruling that a tax credit presupposes an existing tax liability, and since the respondent had no taxable income, no credit could be granted. Upon motion for reconsideration, the CTA reversed itself, ordering the issuance of a tax credit certificate. The CTA held that the credit under RA 7432 is distinct from a refund of erroneously paid taxes and does not require prior tax payment. The Court of Appeals affirmed this ruling.

ISSUE

Whether a private establishment that incurred a net loss for a taxable year may still claim the 20% sales discount granted to senior citizens as a tax credit under RA 7432.

RULING

Yes. The Supreme Court ruled that the 20% discount is a tax credit, not a mere tax deduction. A tax deduction is subtracted from gross income to arrive at taxable income, while a tax credit is subtracted directly from the tax liability itself after computation. RA 7432 unconditionally grants the discount as a tax credit to all covered entities. The law does not condition the grant of this credit upon the existence of a tax liability or the prior payment of taxes.
The Court emphasized that administrative regulations, such as revenue issuances from the BIR, cannot amend, revoke, or impose additional conditions on a clear statutory grant. Since the law is unequivocal, the tax credit must be honored regardless of the taxpayer’s net income position. The credit operates as a form of just compensation for the private property (the discount) taken for public use to benefit a privileged class (senior citizens). Therefore, respondent is entitled to the tax credit certificate for the amount of the discounts granted, notwithstanding its net loss for the year. The Petition was denied.
