G.R. No. 178490 ; July 7, 2009
COMMISSIONER OF INTERNAL REVENUE, Petitioner, vs. BANK OF THE PHILIPPINE ISLANDS, Respondent.

FACTS

For the taxable year 1998, respondent Bank of the Philippine Islands (BPI) computed an overpayment of income taxes amounting to ₱33,947,101.00. In its 1998 Corporate Annual Income Tax Return (ITR), BPI opted to carry over this excess tax credit to the succeeding taxable year 1999 by marking the corresponding box. In 1999, BPI incurred a net loss and thus had no income tax liability against which to apply the carried-over 1998 credit. BPI again indicated a carry-over of the still-unapplied 1998 credit, along with its 1999 excess credits, to the year 2000. In its 2000 ITR, BPI reported zero taxable income and failed to indicate any option to either carry over or seek a refund for the accumulated excess credits.
On April 3, 2001, BPI filed an administrative claim for a refund specifically for the ₱33,947,101.00 representing its 1998 excess creditable income tax. The Commissioner of Internal Revenue (CIR) did not act on the claim, prompting BPI to file a petition before the Court of Tax Appeals (CTA). The CTA denied the claim, ruling that BPI’s initial option in 1998 to carry over the excess credit was irrevocable under Section 76 of the National Internal Revenue Code (NIRC), thus barring a subsequent refund claim. The Court of Appeals reversed the CTA, holding that BPI was entitled to the refund.

ISSUE

Whether BPI’s initial election to carry over its 1998 excess income tax credit to 1999 precludes it from subsequently filing a claim for refund of the same amount.

RULING

No. The Supreme Court affirmed the Court of Appeals and ruled that BPI is entitled to a refund. The Court clarified the application of Section 76 of the NIRC of 1997, which states that the choice to carry over excess credits or seek a refund, once made in the annual return, is irrevocable for that taxable period. The irrevocability rule, however, applies only to the specific taxable year for which the choice is made and does not perpetually bind the taxpayer if the chosen option proves futile.
The legal logic is that the option is irrevocable only insofar as it pertains to the taxable year to which it applies. When BPI opted to carry over its 1998 excess to 1999, it forfeited the right to claim a refund for the taxable year 1998. This irrevocability, however, does not extend to permanently foreclose a refund claim if the carried-over credit cannot be utilized in the subsequent year. Since BPI had a net loss in 1999, it incurred no tax liability against which to apply the 1998 credit. The carry-over option therefore yielded no benefit. At that point, the taxpayer should not be penalized for its initial choice; it may then seek a refund, as the alternative of carrying it over further would be an exercise in futility. The Court emphasized that the government cannot unjustly enrich itself by retaining taxes that are neither due nor can be applied. Consequently, BPI’s claim for refund of its 1998 excess credit, filed within the two-year prescriptive period, was granted.
