Commissioner of Internal Revenue vs. Bank of the Philippine Islands

Once a corporation opts to carry over its excess income tax credit to succeeding taxable years, that option is irrevocable for that taxable period, and no application for refund or issuance of a tax credit certificate may thereafter be allowed for the same excess credit, regardless of whether the credit was actually applied.

The Commissioner of Internal Revenue is the petitioner, and the Bank of the Philippine Islands is the respondent corporation that filed corporate annual income tax returns. The dispute turns on Section 76 of the National Internal Revenue Code of 1997, which allows a corporation whose quarterly income tax payments exceed its total tax due either to seek a refund or to credit the excess against the estimated quarterly income tax liabilities of succeeding taxable years, and which adds that once the carry-over option is chosen it is irrevocable and no refund or tax credit certificate may be allowed. Section 76 reproduced Section 79 of the NIRC of 1985 but added the irrevocability sentence, a change that affects the treatment of prior jurisprudence.

On 15 April 1999, the Bank of the Philippine Islands filed with the Bureau of Internal Revenue its final adjusted Corporate Annual Income Tax Return for the taxable year ending 31 December 1998, showing taxable income of ₱1,773,236,745.00 and total tax due of ₱602,900,493.00. For the same taxable year, BPI had already made income tax payments for the first three quarters amounting to ₱563,547,470.46. It also received income in 1998 from various third persons that had been subjected to expanded withholding taxes amounting to ₱7,685,887.90, acquired a foreign tax credit of $151,467.00, or ₱6,190,014.46, for taxes paid to the United States government on the operations of its New York Branch, and carried over an excess tax credit from 1997 amounting to ₱59,424,222.00. Crediting these amounts against the total tax due, BPI computed an overpayment of ₱33,947,101.00.

BPI opted to carry over its 1998 excess tax credit of ₱33,947,101.00 to the succeeding taxable year ending 31 December 1999. For 1999, BPI ended up with a net loss of ₱615,742,102.00, its still unapplied 1998 excess tax credit of ₱33,947,101.00, and additional excess tax credit acquired in 1999 of ₱12,975,750.00, so that its total excess tax credits increased to ₱46,922,851.00, which it again opted to carry over to the following taxable year. For the taxable year ending 31 December 2000, BPI declared zero taxable income, excess tax credit carried over from 1998 and 1999 amounting to ₱46,922,851.00, and additional excess tax credit gained in 2000 of ₱25,207,939.00; this time it did not indicate in its ITR whether it was carrying over its excess tax credits or claiming a refund or tax credit certificate.

On 3 April 2001, BPI filed with the Commissioner of Internal Revenue an administrative claim for refund of ₱33,947,101.00, representing its excess creditable income tax for 1998. The CIR failed to act on the claim, so BPI filed a Petition for Review before the Court of Tax Appeals, docketed as CTA Case No. 6276. The CTA found that BPI had opted to carry over its excess tax credits by placing an “x” mark on the corresponding box of its 1998 ITR, that BPI again manifested its intention to carry over the credit in its 1999 ITR, and that BPI carried over the excess credits in 2000. The CA conceded that BPI had indeed opted to carry over its 1998 excess tax credit by placing an “x” mark on the corresponding box of its 1998 ITR.

• Irrevocability Rule: Petitioner argued that the CA committed reversible error in holding that the “irrevocability rule” under Section 76 of the Tax Code does not operate to bar BPI from asking for a tax refund.
• Entitlement to Refund: Petitioner argued that the CA committed grave error in reversing and setting aside the CTA Decision and in holding that BPI is entitled to the claimed tax refund.

• Irrevocability of Carry-Over Option: Whether, under Section 76 of the NIRC of 1997, a corporation that has opted to carry over its excess income tax credit to succeeding taxable years is barred from later claiming a refund of the same excess credit when it could not actually apply the credit because it suffered a net loss or had zero tax liability.
• Scope of “For That Taxable Period”: Whether the phrase “for that taxable period” in Section 76 limits the irrevocability of the carry-over option to the immediately succeeding taxable year only.
• Unjust Enrichment: Whether denying a refund under the irrevocability rule amounts to unjust enrichment on the part of the government.
• Proof of Option Chosen: Whether BPI sufficiently established that it chose the refund option rather than the carry-over option for its 1998 excess income tax credit.

• Irrevocability of Carry-Over Option: Yes. Section 76 makes the carry-over option irrevocable once made, and no application for refund or tax credit certificate is allowed; actual application of the credit is irrelevant.
• Scope of “For That Taxable Period”: No. The phrase identifies the excess income tax by the taxable period when it was acquired; it does not make the irrevocability expire after the succeeding taxable year.
• Unjust Enrichment: No. Denial of the refund does not enrich the government because no amount is forfeited; the credit remains in BPI’s account until utilized in succeeding taxable years.
• Proof of Option Chosen: No. BPI did not discharge its burden; it expressly marked the carry-over option in its 1998 ITR and consistently reported the credit in 1999 and 2000, and its later change of mind was barred.

• Irrevocability of Carry-Over Option: Section 76 of the NIRC of 1997 gives a corporation with excess quarterly income tax payments two alternative options: to claim a refund or to carry over the excess credit to succeeding taxable years. The choice of one precludes the other. The last sentence of Section 76 provides that once the carry-over option is made, it is irrevocable for that taxable period and no application for tax refund or issuance of a tax credit certificate shall be allowed. The controlling factor is that the taxpayer chose an option; after opting to carry over, the question of whether it actually gets to apply the credit is irrelevant. BPI expressly indicated in its 1998 ITR that it was carrying over the excess credit, consistently reported the amount in its 1999 and 2000 ITRs as credit to be applied to any tax liability, and only changed its mind when no such opportunity arose because it suffered a net loss in 1999 and had zero tax liability in 2000. BPI itself never denied that its original intention was to carry over the credit. The SC distinguished BPI-Family Savings Bank, Inc. vs. Court of Appeals because that case was decided under Section 79 of the NIRC of 1985, which did not yet contain the irrevocability rule, and followed Philam Asset Management, Inc. vs. Commissioner of Internal Revenue, which held that once the carry-over option is taken, actually or constructively, it becomes irrevocable and admits of no exception.

• Scope of “For That Taxable Period”: The CA read the phrase “for that taxable period” as a prescriptive period limiting the irrevocability of BPI’s carry-over option to the 1999 taxable period, such that when 1999 expired BPI was free to choose refund. The SC rejected this. The phrase merely identifies the excess income tax subject of the option by referring to the taxable period when it was acquired by the taxpayer. BPI’s excess income tax credit was acquired in 1998; its option to carry over that 1998 credit was irrevocable, and it could not later apply for a refund of the very same 1998 excess credit. The CA’s interpretation would render nugatory the irrevocability rule and merely delay the taxpayer’s flip-flopping to the end of each succeeding taxable period. The evident legislative intent in adding the last sentence to Section 76 was to keep the taxpayer from flip-flopping on its options and to avoid confusion and complication regarding the excess tax credit.

• Unjust Enrichment: The CA declared that denying BPI’s refund because of the irrevocability rule would amount to unjust enrichment on the part of the government. The SC disagreed, adopting the reasoning in Philam that there is no unjust enrichment because there is no forfeiture of any amount in favor of the government. The amount claimed as a refund remains in the taxpayer’s account until utilized in succeeding taxable years under Section 76. Unlike the refund option, which prescribes after two years from the filing of the final adjustment return, the carry-over of excess income tax credit has no prescriptive period. BPI’s 1998 excess tax credit may therefore be repeatedly carried over to 1999, 2000, 2001, and so on, until actually applied or credited to a tax liability.

• Proof of Option Chosen: Which option the taxpayer chose is generally a matter of evidence, and the claimant bears the burden of proving the factual basis of its claim for tax credit or refund. Tax refunds, like tax exemptions, are construed strictly against the taxpayer. Failure to mark an option in the ITR does not automatically mean that the taxpayer opted for a tax credit; under Philam, a written claim for refund may effectively express a choice for refund. But here BPI expressly marked the carry-over option in its 1998 ITR and consistently reported the amount in its 1999 and 2000 ITRs as a credit. The final adjustment return is the most reliable firsthand evidence of corporate acts pertaining to income taxes. BPI did not discharge its burden. Its reiteration of the carry-over option in its 1999 ITR was a superfluity because its 1998 choice was already irrevocable, and its failure to indicate any option in its 2000 ITR was immaterial to its 1998 excess tax credit.

• Alternative options under Section 76 — A corporation whose quarterly income tax payments exceed its total tax due may either claim a refund or carry over the excess credit to succeeding taxable years. The two options are alternative; the choice of one precludes the other, and the taxpayer cannot get both a refund and a tax credit for the same excess taxes. The SC applied this to BPI, which chose carry-over in its 1998 ITR.
• Irrevocability of the carry-over option — Once a corporation opts to carry over its excess quarterly income tax against income tax due for succeeding taxable years, the option is irrevocable for that taxable period and no refund or tax credit certificate may be allowed. The SC applied this to bar BPI’s refund despite its inability to apply the credit.
• Actual application is irrelevant once the option is made — The carry-over option is complete upon the taxpayer’s choice; whether the taxpayer actually gets to apply the credit is irrelevant. The SC applied this because BPI’s net loss in 1999 and zero tax liability in 2000 did not reopen the refund option.
• “For that taxable period” identifies the excess credit, not a prescriptive period — The phrase refers to the taxable period when the excess credit was acquired; it does not limit the irrevocability of the carry-over option to the immediately succeeding taxable year. The SC applied this to hold that BPI’s 1998 excess credit remained irrevocably committed to carry-over.
• No unjust enrichment where carry-over is chosen — Denial of a refund does not forfeit the credit in favor of the government; the amount remains in the taxpayer’s account until utilized, and the carry-over has no prescriptive period. The SC applied this to reject the CA’s unjust enrichment argument.
• Tax refund claimant’s burden and the FAR as evidence — Tax refunds are construed strictly against the taxpayer, and the choice of option is a matter of evidence; the final adjustment return is the most reliable firsthand evidence of corporate tax acts. The SC applied this to BPI’s 1998 ITR and later returns, which showed carry-over.

• “Once the option to carry-over and apply the excess quarterly income tax against income tax due for the taxable quarters of the succeeding taxable years has been made, such option shall be considered irrevocable for that taxable period and no application for tax refund or issuance of a tax credit certificate shall be allowed therefor.” — This is the last sentence of Section 76 as quoted by the SC, the core statutory basis for barring BPI’s refund.
• “Consequently, after the taxpayer opts to carry-over its excess tax credit to the following taxable period, the question of whether or not it actually gets to apply said tax credit is irrelevant.” — The SC rejects the CA’s distinction that BPI never actually carried over the credit because it had no tax liability to apply it to.
• “The phrase “for that taxable period” merely identifies the excess income tax, subject of the option, by referring to the taxable period when it was acquired by the taxpayer.” — The SC construes the phrase against the CA’s reading that irrevocability expired after 1999.
• “There can be no doubt that BPI opted to carry over its excess income tax credit from 1998; it only subsequently changed its mind – which it was barred from doing by the irrevocability rule.” — The SC concludes that BPI’s initial carry-over choice was definitive and its later refund claim was a barred change of mind.

• BPI-Family Savings Bank, Inc. vs. Court of Appeals, 386 Phil. 719 (2000) — Distinguished; it involved a tax credit acquired in 1989 under Section 79 of the NIRC of 1985, before the irrevocability rule existed, and cannot be a precedent for Section 76 of the NIRC of 1997.
• Philam Asset Management, Inc. vs. Commissioner of Internal Revenue, G.R. Nos. 156637 and 162004, 14 December 2005, 477 SCRA 761 — Followed as controlling precedent; it recognized the two alternative options under Section 76, held the carry-over option irrevocable once taken actually or constructively, and ruled out unjust enrichment.
• Paseo Realty and Development Corporation vs. Court of Appeals, G.R. No. 119286, 13 October 2004, 440 SCRA 235 — Cited for the rule that tax refunds, like tax exemptions, are construed strictly against the taxpayer.

• Section 76, National Internal Revenue Code of 1997 — The Final Adjustment Return provision allows a corporation either to pay the excess tax still due or to be refunded the excess amount paid, and permits the refundable amount to be credited against estimated quarterly income tax liabilities for succeeding taxable years. Its last sentence lays down the irrevocability rule. The SC applied it to bar BPI’s refund after BPI marked the carry-over option in its 1998 ITR. The provision took effect on 1 January 1998.
• Section 79, National Internal Revenue Code of 1985 — The predecessor provision allowed a taxpayer with excess income tax to either refund the amount or credit it to tax liability for succeeding taxable periods, but it did not contain the irrevocability sentence. The SC applied it to distinguish BPI-Family, noting that the provision was erroneously cited as Section 69 in that case but was renumbered as Section 79 of the NIRC of 1985.
