San Roque Power Corporation vs. Commissioner of Internal Revenue

A VAT-registered taxpayer may claim a refund of unutilized input VAT under Section 112(A) of the NIRC on the basis of a "deemed sale" under Section 106(B) of the NIRC, even if the transaction was not a commercial sale in the normal course of business, provided all other statutory requisites are satisfied and the claim is supported by sufficient evidence.

San Roque Power Corporation was incorporated on October 14, 1997, for the sole purpose of building and operating the San Roque Multipurpose Project in San Manuel, Pangasinan, consisting of a power station, dam, spillway, and related facilities. It was registered with the Board of Investments on a preferred pioneer status and with the BIR as a VAT taxpayer. On October 11, 1997, petitioner entered into a Power Purchase Agreement (PPA) with the National Power Corporation (NPC), under which petitioner would design, construct, and operate the Power Station, and NPC would purchase all electricity generated during a 25-year cooperation period. NPC enjoys comprehensive tax exemption under Section 13 of Republic Act No. 6395 (NPC Charter), which declares it exempt from all taxes, duties, fees, imposts, and other charges. Section 6 of Republic Act No. 9136 (EPIRA Law) further provides that sales of generated power by generation companies shall be VAT zero-rated. The BIR granted petitioner five Certificates of Zero Rate, commencing on September 27, 1998 and continuing throughout 2002, on the basis that petitioner's sale of power to NPC is subject to VAT at zero percent rate under Section 108(B)(3) of the NIRC, which covers services rendered to persons or entities whose exemption under special laws effectively subjects the supply of such services to zero percent rate.

San Roque Power Corporation was incorporated on October 14, 1997, for the sole purpose of building and operating the San Roque Multipurpose Project in San Manuel, Pangasinan, an indivisible project consisting of a power station, dam, spillway, and related facilities. It was registered with the Board of Investments on a preferred pioneer status and with the BIR as a VAT taxpayer. On October 11, 1997, petitioner entered into a Power Purchase Agreement (PPA) with the National Power Corporation (NPC) to develop the hydro potential of the Lower Agno River and generate additional power for the Luzon Power Grid. Under the PPA, petitioner was responsible for the design, construction, installation, completion, testing, and commissioning of the Power Station, and would operate and maintain it subject to NPC's instructions. During a 25-year cooperation period commencing from the completion date, NPC would purchase all electricity generated by the plant.

Because of the exclusive nature of the PPA, petitioner applied for and was granted five Certificates of Zero Rate by the BIR, with the zero-rated status commencing on September 27, 1998 and continuing throughout 2002. For the period January to December 2002, petitioner filed its Monthly VAT Declarations and Quarterly VAT Returns, which showed excess input VAT payments on account of importation and domestic purchases of goods and services. Petitioner filed four separate administrative claims for refund with the BIR on June 19, 2002, October 25, 2002, February 27, 2003, and May 29, 2003, seeking to recover a total of ₱250,258,094.25, later amended to ₱249,397,620.18, representing unutilized excess VAT on importation and domestic purchases for the year 2002. Petitioner also amended its Quarterly VAT Returns to reflect corrections in input VAT on domestic purchases and importations.

Respondent failed to act on the request for tax refund or credit, prompting petitioner to file a Petition for Review with the CTA in Division on April 5, 2004, before the two-year prescriptive period lapsed. During the proceedings, petitioner presented its amended quarterly VAT returns, a special audit report prepared by the CPA firm Punongbayan and Araullo, sales invoices and official receipts, audited financial statements, and the affidavit of its Vice President and Director of Finance, Carlos Echevarria. The audit report identified items with incomplete documentation and computational errors totaling ₱3,266,009.78, leaving ₱246,131,610.40 as properly documented and recorded input VAT. Echevarria admitted that no commercial sale of electricity had been made to NPC in 2002 since the project was still under construction. However, petitioner's fourth quarter return for 2002 reported a zero-rated sale of ₱42,500,000.00, representing electricity produced and transferred to NPC during the testing period under a cost recovery scheme. Both the CTA Second Division and the CTA En Banc denied the claim, finding that petitioner made no zero-rated or effectively zero-rated sales in 2002 and that the evidence was insufficient to prove that the purchases qualified as capital goods under Revenue Regulations No. 7-95.

• Appreciation of Evidence: Petitioner argued that the CTA En Banc committed serious error and grave abuse of discretion tantamount to lack or excess of jurisdiction in failing or refusing to appreciate the overwhelming and uncontroverted evidence submitted by petitioner, thereby depriving petitioner of its property without due process.
• Entitlement to Refund Despite Absence of Commercial Sales: Petitioner maintained that the CTA committed serious error in ruling that the absence of zero-rated sales during the year covered by the claim for refund does not entitle petitioner to a refund of its excess VAT input taxes attributable to zero-rated sales, contrary to provisions of law.

• Strict Construction of Tax Refunds: Respondent contended that a tax refund, being in the nature of a tax exemption, should be construed strictissimi juris against the taxpayer.

• Qualification of "Sale" for Zero-Rating Purposes: Whether the transfer of electricity to NPC during the testing period, though not a commercial sale, constitutes a "sale" for purposes of Section 112(A) of the NIRC, thereby entitling petitioner to claim a refund of unutilized input VAT attributable to zero-rated or effectively zero-rated sales.
• Entitlement to Refund: Whether petitioner is entitled to a refund or tax credit in the amount of ₱249,397,620.18 (as amended) representing unutilized input VAT paid on importation and purchases of capital and other taxable goods and services from January 1 to December 31, 2002.

• Qualification of "Sale" for Zero-Rating Purposes: Yes. The transfer of electricity to NPC during the testing period constitutes a "deemed sale" under Section 106(B) of the NIRC, and the term "sale" in Section 112(A) should be construed to include deemed sales, as the same term is broadly defined for purposes of imposing VAT.
• Entitlement to Refund: Yes, in the reduced amount of ₱246,131,610.40. Petitioner satisfied all nine requisites for a refund under Section 112(A) of the NIRC, and the claim was sufficiently supported by documentary evidence including the court-commissioned audit report.

• Qualification of "Sale" for Zero-Rating Purposes: Section 112(A) of the NIRC does not limit the definition of "sale" to commercial transactions in the normal course of business. Section 106(B) of the NIRC, which deals with the imposition of VAT, extends the term "sale" to transactions "deemed" as sale, including the transfer, use, or consumption not in the course of business of goods or properties originally intended for sale or for use in the course of business. An equitable construction of the law requires that when the term "sale" is made to include certain transactions for the purpose of imposing a tax, those same transactions should be included when considering the availability of a tax benefit from the same revenue measures. Petitioner transferred electricity to NPC during the fourth quarter of 2002 in exchange for ₱42,500,000.00. Although this was not a commercial sale, it was a deemed sale under the law. The seventh requirement regarding foreign currency exchange proceeds was inapplicable because the transaction did not involve foreign exchange. The eighth requirement regarding proportionate allocation was inapplicable because there was only a single effectively zero-rated sale transaction and no exempt or taxable sales requiring allocation. As to the ninth requirement, the claim was filed within two years after the close of the taxable quarter for three of the four quarters; for the second quarter, the claim was filed prematurely on October 25, 2002, before the last quarter closed on December 31, 2002. Despite this procedural lapse, the Court found that substantial justice, equity, and fair play favored petitioner, given that there was no danger of fraudulent claims and the government should not keep money not belonging to it.

• Entitlement to Refund: Petitioner satisfied all nine criteria for a refund under Section 112(A): (1) it was a VAT-registered taxpayer, as evidenced by Certificate of Registration No. OCN-98-006-007394; (2) it was engaged in providing electricity to NPC, an activity subject to zero rate under Section 108(B)(3) of the NIRC; (3) input taxes were due or paid, as evidenced by suppliers' VAT invoices, official receipts, and Import Entries and Internal Revenue Declarations examined by the court-commissioned independent CPA; (4) the input taxes were not transitional input taxes under Section 111 of the NIRC; (5) the input taxes had not been applied against output taxes, as confirmed by the audit report showing the claimed input VAT was net of input VAT already offset against output VAT; (6) the input taxes were attributable to zero-rated or effectively zero-rated sales, specifically the deemed sale of electricity to NPC; (7) the foreign currency exchange proceeds requirement was inapplicable; (8) the proportionate allocation requirement was inapplicable; and (9) the claim was filed within two years after the close of the taxable quarter for three of the four quarters. The court-commissioned audit report by Punongbayan & Araullo confirmed that, of the ₱249,397,620.18 claimed, items with incomplete documentation and computational errors totaled ₱3,266,009.78, leaving ₱246,131,610.40 as properly documented and recorded. The Court further held that the strictissimi juris doctrine does not bar a refund when the claim has a clear legal basis and is sufficiently supported by evidence. Under the principle of solutio indebiti in Article 2154 of the Civil Code, the BIR received something when there was no right to demand it and has the obligation to return it. The Court also noted that effective zero-rating was intended to relieve exempt entities like NPC from the burden of indirect tax, and that denying petitioner the tax benefit would undermine the declared policies of the EPIRA Law to ensure total electrification, lower electricity rates, and attract foreign investment.

• Strictissimi Juris in Tax Refunds and Exemptions — Tax refunds, being in the nature of tax exemptions, are construed strictissimi juris against the taxpayer. However, when the claim for refund has a clear legal basis and is sufficiently supported by evidence, the Court shall not hesitate to grant the same. In this case, the Court found that petitioner's claim had clear legal basis under Section 112(A) of the NIRC and was supported by documentary evidence and the court-commissioned audit report, warranting application of the exception.

• Solutio Indebiti — Under Article 2154 of the Civil Code, if something is received when there is no right to demand it, and it was unduly delivered through mistake, the obligation to return it arises. The Court applied this principle to hold that the BIR received the excess input VAT payments without right to retain them, and must return the same to petitioner.

• Equitable Construction of "Sale" in VAT Provisions — When the term "sale" is made to include certain transactions for the purpose of imposing a tax, those same transactions should be included in the term "sale" when considering the availability of an exemption or tax benefit from the same revenue measures. The Court applied this principle to hold that "deemed sales" under Section 106(B) of the NIRC qualify as "sales" for purposes of claiming input VAT refund under Section 112(A).

• Purpose of Effective Zero-Rating — Effective zero-rating is not intended as a benefit to the person legally liable to pay the tax, but to relieve certain exempt entities from the burden of indirect tax shifted to them by their suppliers, so as to encourage the development of particular industries. The Court relied on this principle to hold that petitioner's zero-rated status was meant to relieve NPC of the burden of additional costs that petitioner might shift to NPC.

• "After carefully examining this provision, this Court finds it an equitable construction of the law that when the term 'sale' is made to include certain transactions for the purpose of imposing a tax, these same transactions should be included in the term 'sale' when considering the availability of an exemption or tax benefit from the same revenue measures." — This passage articulates the ratio decidendi: the equitable principle that the broad definition of "sale" for VAT imposition purposes must equally apply when determining entitlement to VAT refunds, thereby allowing deemed sales to qualify zero-rated transactions.

• "Technicalities and legalisms, however exalted, should not be misused by the government to keep money not belonging to it, thereby enriching itself at the expense of its law-abiding citizens." — This statement reflects the Court's equitable stance against the government's retention of taxes improperly collected, grounding the decision in principles of justice and fair play.

• "In performing the procedures referred under the Procedures Performed section of this report, no matters came to our attention that cause us to believe that the amount of input VAT applied for as tax credit certificate/refund of P249,397,620.18 for the period January 1, 2002 to December 31, 2002 should be adjusted except for input VAT claimed with incomplete documentation, those with various and other exceptions on the supporting documents and those with errors in computation totaling P3,266,009.78." — This excerpt from the court-commissioned audit report (Exhibit "J-2") established the evidentiary basis for the refund amount of ₱246,131,610.40, the figure ultimately awarded by the Court.

• "The legislative grant of tax relief (whether in the EPIRA Law or the Tax Code) constitutes a sovereign commitment of Government to taxpayers that the latter can avail themselves of certain tax reliefs and incentives in the course of their business activities here." — This passage frames tax incentives as sovereign commitments essential to maintaining investor confidence, particularly for foreign investors in long-term infrastructure projects.

• Intel Technology of the Philippines, Inc. vs. Commissioner of Internal Revenue, G.R. No. 166732, April 27, 2007, 522 SCRA 657 — Cited for the nine requisites for claiming a refund or tax credit of input VAT under Section 112(A) of the NIRC. The Court applied this framework to evaluate petitioner's compliance with each requirement.
• State Land Investment Corporation vs. Commissioner of Internal Revenue, G.R. No. 171956, January 18, 2008, 542 SCRA 114 — Cited for the exceptions to the rule that the Supreme Court is not a trier of facts, and for the principle of solutio indebiti in tax refund cases. The Court invoked the exception where the judgment is premised on a misapprehension of facts to justify its review of the evidence.
• Philippine Geothermal, Inc. vs. Commissioner of Internal Revenue, G.R. No. 154028, July 29, 2005, 456 SCRA 308 — Cited for the principle that limiting NPC's tax exemption to direct taxes, notwithstanding the general and broad language of the statute, would thwart the legislative intention to grant exemption from all forms of taxes and impositions.
• Philippine Airlines vs. Commissioner of Internal Revenue, G.R. No. 180043, August 14, 2009 — Cited for the proposition that while tax refunds are construed strictissimi juris against the taxpayer, the Court shall not hesitate to grant a refund when the claim has a clear legal basis and is sufficiently supported by evidence.

• Section 112(A) and (B), NIRC of 1997 — Governs refunds or tax credits of input tax for zero-rated or effectively zero-rated sales (Section 112(A)) and for capital goods purchases (Section 112(B)). The Court held that petitioner was entitled to a refund under Section 112(A) based on its deemed sale of electricity to NPC, rendering resolution under Section 112(B) unnecessary.
• Section 106(B), NIRC of 1997 — Enumerates transactions deemed as sales for VAT purposes, including transfer, use, or consumption not in the course of business of goods or properties originally intended for sale or for use in the course of business. The Court applied this provision to hold that petitioner's transfer of electricity to NPC during testing constituted a deemed sale.
• Section 108(B)(3), NIRC of 1997 — Provides that services rendered to persons or entities whose exemption under special laws or international agreements effectively subjects the supply of such services to zero percent rate are subject to zero percent VAT. Petitioner's sale of power to NPC was zero-rated under this provision because NPC is tax-exempt under its charter.
• Section 111, NIRC of 1997 — Defines transitional or presumptive input tax credits as input taxes allowed on the beginning inventory of goods, materials, and supplies. The Court found that petitioner's input taxes were not transitional input taxes.
• Section 13, Republic Act No. 6395 (NPC Charter) — Declares NPC exempt from all taxes, duties, fees, imposts, and other charges imposed by the Republic of the Philippines and its political subdivisions. The Court relied on this provision to confirm that NPC's exemption extends to indirect taxes, justifying the effective zero-rating of petitioner's sales to NPC.
• Section 6, Republic Act No. 9136 (EPIRA Law) — Provides that sales of generated power by generation companies shall be VAT zero-rated, pursuant to the objective of lowering electricity rates to end-users. The Court cited this provision to reinforce the legislative policy supporting petitioner's claim.
• Article 2154, Civil Code of the Philippines — Embodies the principle of solutio indebiti: if something is received when there is no right to demand it, the obligation to return it arises. The Court applied this principle to hold that the BIR must return the excess input VAT payments.

Associate Justices Renato C. Corona, Presbitero J. Velasco, Jr., Antonio Eduardo B. Nachura, and Diosdado M. Peralta concurred in the decision. No separate concurring opinions were written.
