CBK Power Company Limited vs. Commissioner of Internal Revenue

The 120-day period for the Commissioner of Internal Revenue to act on an administrative claim for refund or credit of input tax and the 30-day period to appeal to the Court of Tax Appeals from the denial or deemed denial thereof are mandatory and jurisdictional prerequisites under Section 112(D) of the National Internal Revenue Code of 1997; BIR Ruling No. DA-489-03, which constitutes equitable estoppel against the government, applies only to excuse premature judicial claims (filed before the lapse of the 120-day period) and does not validate judicial claims filed after the expiration of the 30-day appeal period.

CBK Power Company Limited operates the Kalayaan I and II hydroelectric power plants and related facilities in Laguna, selling electricity to the National Power Corporation (NPC). On December 29, 2004, the Bureau of Internal Revenue approved petitioner's application for VAT zero-rating under Section 108(B)(3) of the National Internal Revenue Code for sales to NPC covering January 1, 2005 to October 31, 2005. Consequently, petitioner filed administrative claims for tax credit certificates for alleged unutilized input taxes on local purchases and capital goods for the first three quarters of 2005. Alleging inaction by the Commissioner, petitioner instituted a judicial claim with the Court of Tax Appeals on April 18, 2007.

• VAT Zero-Rating Approval: Petitioner is a VAT-registered entity engaged in operating hydroelectric power plants. On December 29, 2004, the Bureau of Internal Revenue approved its application for effectively zero-rated VAT status for sales of electricity to the National Power Corporation (an entity exempt from direct and indirect taxes) covering the period January 1, 2005 to October 31, 2005.
• Administrative Claims for Refund: Pursuant to Sections 112(A) and (B) of the National Internal Revenue Code, petitioner filed administrative claims for the issuance of tax credit certificates for unutilized input taxes on local purchases of goods and services and on capital goods for the first, second, and third quarters of 2005 on June 30, 2005, September 15, 2005, and October 28, 2005, respectively.
• Judicial Claim: On April 18, 2007, petitioner filed a Petition for Review with the Court of Tax Appeals, alleging that the Commissioner of Internal Revenue had failed to act on its administrative claims.
• Lower Court Determinations: The Court of Tax Appeals Special Second Division found that the administrative claims were timely filed within the two-year prescriptive period reckoned from the close of each taxable quarter under Section 112(A), but ruled that the judicial claim for the first quarter was filed out of time; it partly granted the claims for the second and third quarters. The Court of Tax Appeals En Banc reversed, finding that the judicial claims for all three quarters were filed beyond the reglementary period under Section 112(D).

• Retroactivity of Mirant: Petitioner maintained that Commissioner of Internal Revenue v. Mirant Pagbilao Corporation, which clarified the reckoning point for the prescriptive period, was not yet in existence when it filed its administrative claims in 2005, and thus should not be applied retroactively to prejudice its claims.
• Timeliness of Administrative Claims: Petitioner argued that its administrative claims were filed well within the two-year prescriptive period from the close of the taxable quarters when the effectively zero-rated sales were made, as provided in Section 112(A) of the National Internal Revenue Code.
• Retroactivity of Aichi: Petitioner contended that Commissioner of Internal Revenue v. Aichi Forging Company of Asia, Inc., which held that the 120+30 day periods are mandatory and jurisdictional, should not be applied retroactively to bar its claims.

• Mandatory Nature of 120+30 Day Period: The Commissioner of Internal Revenue countered that Section 112(D) of the National Internal Revenue Code establishes mandatory and jurisdictional periods: a 120-day period for the Commissioner to decide on the administrative claim and a 30-day period to appeal to the Court of Tax Appeals from the denial or deemed denial.
• Late Filing: Respondent argued that petitioner filed its judicial claim on April 18, 2007, long after the expiration of the 30-day period following the 120-day period for each of the quarters claimed, rendering the petition time-barred.
• Inapplicability of BIR Ruling No. DA-489-03: Respondent maintained that BIR Ruling No. DA-489-03, which allowed taxpayers to file judicial claims without waiting for the 120-day period to lapse, only excused premature filing, not late filing; since petitioner filed its judicial claim after the reglementary periods had expired, it could not invoke the ruling.

• Prescriptive Period for Judicial Claims: Whether the petitioner filed its judicial claim for refund of unutilized input VAT within the mandatory periods prescribed by Section 112(D) of the National Internal Revenue Code.
• Applicability of BIR Ruling No. DA-489-03: Whether petitioner may rely on BIR Ruling No. DA-489-03 to excuse its failure to comply with the 120+30 day periods where the judicial claim was filed after the expiration of the 30-day appeal period.
• Availability of Solutio Indebiti: Whether the principle of solutio indebiti applies to allow recovery of input taxes paid where the statutory periods for refund have prescribed.

• Prescriptive Period for Judicial Claims: The 120-day period for the Commissioner to act on an administrative claim and the 30-day period to appeal to the Court of Tax Appeals are mandatory and jurisdictional under Section 112(D) of the National Internal Revenue Code. Petitioner filed its judicial claim on April 18, 2007, which was long after the expiration of the 30-day period following the 120-day period for each of the second and third quarters of 2005; specifically, for the second quarter, the 30-day period expired on February 13, 2006, and for the third quarter, on March 28, 2006. The failure to comply with these periods resulted in the loss of the right to claim a refund.
• Applicability of BIR Ruling No. DA-489-03: BIR Ruling No. DA-489-03 constitutes equitable estoppel against the government and applies to all taxpayers from its issuance on December 10, 2003 until its reversal in Aichi on October 6, 2010; however, the ruling only allowed premature filing of judicial claims (filing before the lapse of the 120-day period), not late filing. Since petitioner filed its judicial claim long after the 30-day period had expired, rather than prematurely, it cannot claim the benefit of the exception.
• Availability of Solutio Indebiti: The principle of solutio indebiti does not apply to claims for tax refunds because the elements are wanting: a binding legal relation existed between petitioner and the Commissioner (taxpayer and government), and the payment of input VAT was not made through mistake but was a correct and proper payment at the time it was made, pursuant to the VAT system's distinctive nature. The entitlement to a refund arises solely from statutory compliance, not from quasi-contract.
• Strict Construction of Tax Refunds: Tax refunds or credits, like tax exemptions, are strictly construed against the taxpayer; the burden rests on the taxpayer to demonstrate strict compliance with the conditions for the grant of the tax refund or credit.

• Mandatory and Jurisdictional Periods for VAT Refund — Section 112(D) of the National Internal Revenue Code imposes two mandatory and jurisdictional periods for claims for refund or credit of input tax: (1) a 120-day period from the submission of complete documents within which the Commissioner must decide the administrative claim; and (2) a 30-day period from the receipt of the denial decision or from the expiration of the 120-day period (deemed denial) within which the taxpayer must appeal to the Court of Tax Appeals. Compliance with both periods is essential for the exercise of the statutory privilege to claim a refund.
• Equitable Estoppel and BIR Ruling No. DA-489-03 — BIR Ruling No. DA-489-03, being a general interpretative rule issued in response to a government agency query, created equitable estoppel against the government, allowing taxpayers to file judicial claims for VAT refund without waiting for the lapse of the 120-day period (premature filing) from December 10, 2003 until October 6, 2010. However, this exception strictly applies only to premature filings and does not extend to late filings made after the expiration of the 30-day appeal period.
• Solutio Indebiti in Taxation — The quasi-contract of solutio indebiti requires: (1) payment made when no binding relation exists between the payor (who has no duty to pay) and the recipient; and (2) payment made through mistake, not liberality or other causes. The doctrine does not apply to tax refund claims because a binding taxpayer obligation exists between the government and the taxpayer, and the payment of input VAT is legally due at the time of payment, not made through mistake.
• Reckoning Point for Administrative Claims — For VAT-registered persons whose sales are zero-rated or effectively zero-rated, the two-year prescriptive period for filing administrative claims for refund or credit of input tax is reckoned from the close of the taxable quarter when the sales were made, pursuant to Section 112(A) of the National Internal Revenue Code.

• "Compliance with both periods is jurisdictional. The period of 120 days is a prerequisite for the commencement of the 30-day period to appeal to the CTA." — Establishes the mandatory and jurisdictional nature of the sequential periods under Section 112(D).
• "BIR Ruling No. DA-489-03 allowed premature filing of a judicial claim, which means non-exhaustion of the 120-day period for the Commissioner to act on an administrative claim, but not its late filing." — Clarifies the limited scope of the equitable estoppel exception.
• "Equity, which has been aptly described as 'a justice outside legality,' is applied only in the absence of, and never against, statutory law or judicial rules of procedure." — Affirms that equity cannot override mandatory statutory periods for tax refunds.
• "Tax refunds or credits, just like tax exemptions, are strictly construed against the taxpayer." — Reinforces the strict construction doctrine in tax refund cases.

• Commissioner of Internal Revenue v. San Roque Power Corporation, G.R. Nos. 187485, 196113 and 197156, February 12, 2013 — Controlling precedent establishing that the 120+30 day periods are mandatory and jurisdictional, and that BIR Ruling No. DA-489-03 created equitable estoppel applicable to premature filings from December 10, 2003 to October 6, 2010.
• Commissioner of Internal Revenue v. Aichi Forging Company of Asia, Inc., G.R. No. 184823, October 6, 2010, 632 SCRA 422 — Held that the 120+30 day periods are mandatory and jurisdictional, reversing the previous allowance for premature filing.
• Commissioner of Internal Revenue v. Mirant Pagbilao Corporation, G.R. No. 172129, September 12, 2008, 565 SCRA 154 — Clarified that the two-year prescriptive period for administrative claims is reckoned from the close of the taxable quarter when the sales were made, not from the date of payment of the output VAT.
• Atlas Consolidated Mining and Development Corporation v. Commissioner of Internal Revenue, G.R. No. L-19249, June 8, 2007 — Earlier doctrine (abandoned by Mirant and Aichi) which reckoned the two-year period from the date of filing of the return and payment of the tax; held inapplicable to the 120+30 day periods.

• Section 112(A), National Internal Revenue Code of 1997 — Governs refunds or tax credits of input tax for zero-rated or effectively zero-rated sales; prescribes the two-year period from the close of the taxable quarter when the sales were made for filing administrative claims.
• Section 112(D), National Internal Revenue Code of 1997 — Mandates that the Commissioner grant a refund or issue a tax credit certificate within 120 days from submission of complete documents, and allows the taxpayer to appeal to the Court of Tax Appeals within 30 days from receipt of denial or from expiration of the 120-day period.
• Section 108(B)(3), National Internal Revenue Code of 1997 — Classifies services rendered to persons engaged in business outside the Philippines or to non-resident persons not engaged in business in the Philippines as effectively zero-rated sales, applicable to sales to the National Power Corporation by virtue of its tax-exempt charter.
