G.R. No. 155855 - Buac vs. Commission on Elections

Case Summary (G.R. No. 155855)

Factual Background

Maibarara Geothermal, Inc. is a Philippine corporation registered as a Renewable Energy Developer for a 20 MW geothermal power project and as a VAT taxpayer with the Bureau of Internal Revenue. MGI filed four administrative claims seeking refund or tax credit of alleged unutilized input VAT attributable to zero-rated sales for each fiscal quarter of taxable year 2013, totaling PHP 81,572,707.81. The CIR failed to act on the administrative claims, prompting MGI to file petitions for review with the CTA.

Administrative Claims and CTA Proceedings

MGI pursued de novo review before the CTA in CTA Case Nos. 9119, 9201, 9254, and 9336. The CTA Division consolidated the petitions and conducted factfinding and documentary review, including an examination of MGI’s quarterly VAT returns, audited financial statements, an official receipt dated March 25, 2014 (Official Receipt No. 0501), and witness affidavits from MGI’s Accounting Manager and Legal Officer.

Ruling of the CTA Division

The CTA Special First Division denied MGI’s consolidated petitions by Decision dated March 4, 2019. The Division applied controlling jurisprudence that a taxpayer must establish actual zero-rated or effectively zero-rated sales to succeed in a claim for refund or credit of input VAT. It found from MGI’s quarterly VAT returns and witness admissions that MGI had no sales during taxable year 2013 and that its first sale of electricity to Trans-Asia Oil and Energy Development Corporation occurred in February 2014. The Division concluded that, in the absence of zero-rated sales to which the input VAT could be attributed, MGI failed to meet the basic statutory and evidentiary requisites for refund under Section 112(A) of the NIRC.

Ruling of the CTA En Banc

The CTA En Banc affirmed the Division in its November 26, 2020 Decision. The En Banc agreed that the existence of zero-rated sales is a requisite for a Section 112(A) claim and that the two‑year prescriptive period for filing an administrative refund claim is reckoned from the close of the taxable quarter when the zero-rated sales were made. Citing San Roque Power Corporation v. Commissioner of Internal Revenue, Luzon Hydro Corporation v. Commissioner of Internal Revenue, and other precedents, the En Banc held that MGI failed to establish zero-rated sales in 2013 or any subsequent period and that Official Receipt No. 0501 was illegible and insufficient to substantiate the claimed sales. The En Banc further held that, under the DOE IRR then in force, an RE developer must present three documents to qualify purchases for VAT zero-rating: DOE Certificate of Registration, BOI Certificate of Registration, and a per-transaction Certificate of Endorsement from the DOE.

Dissenting Opinion at the CTA En Banc

A Dissenting Opinion by Associate Justice Bacorro‑Villena, joined by Associate Justice Manahan, took the view that a DOE Certificate of Endorsement is required only for duty-free importation incentives under the BOI terms and not for VAT zero-rating, and that MGI had established zero-rated sales for the first quarter of 2014 in a separate CTA decision granting refund for input VAT incurred in 2012.

Issues Presented to the Supreme Court

The Supreme Court framed two principal issues: (1) whether the CTA En Banc erred in ruling that MGI failed to establish qualification as an entity engaged in zero-rated sales under Republic Act No. 9513 and its IRR, and (2) whether the CTA En Banc erred in affirming the Division’s denial of MGI’s Section 112(A) refund claims for taxable year 2013.

Parties’ Contentions before the Supreme Court

MGI argued that a DOE Certificate of Endorsement is not a statutory prerequisite to VAT zero-rating under Section 15(g) of Republic Act No. 9513 and that the RE developer’s DOE Certificate of Registration sufficed. MGI also urged that the CTA’s factual findings were tainted by grave abuse of discretion and misapprehension of facts, inviting the Court to reappreciate Official Receipt No. 0501 and other documentary evidence, and to take judicial notice of a separate CTA decision where the En Banc granted MGI a refund for input VAT incurred in 2012. The CIR defended the CTA findings and the application of Section 112(A) jurisprudence requiring proof of zero-rated sales and the evidentiary sufficiency of VAT returns and receipts.

Standard of Review on Findings of Fact

The Court reiterated that it is not a trier of facts and that CTA factual findings are generally binding and entitled to respect. The Court stated that MGI must show convincing proof of grave abuse of discretion or misapprehension of facts to warrant judicial reappraisal. The Court found that MGI did not meet that burden and that the exceptions to the rule against reweighing evidence did not apply.

Whether MGI Qualified for VAT Zero-Rating under Republic Act No. 9513

The Court analyzed Section 15(g) of Republic Act No. 9513, Section 108(B)(7) and Section 112(A) of the NIRC, and the DOE IRR provisions. The ponencia initially recognized the DOE’s authority under Section 26 of RA 9513 to issue certifications and to prescribe further requirements. The Court examined the IRR requirement of a per-transaction DOE Certificate of Endorsement and the legislative history of the RE Law. Applying principles of subordinate legislation and statutory construction, the Court concluded that the DOE exceeded the authority intended by Congress when the IRR required a per-transaction Certificate of Endorsement as a prerequisite to the VAT zero-rating incentive. The Court construed Sections 25 and 26 and the legislative record to mean that registration and DOE certification were the primary predicates for incentives, but that the Legislature’s omission of the VAT zero-rating incentive from the enumeration of entitlements in the Senate precursor to Section 26 rendered the per-transaction endorsement inapplicable to VAT zero-rating. The Court therefore held that a Certificate of Endorsement on a per-transaction basis was not a valid precondition for VAT zero-rating; registration with the DOE (and BOI where applicable) sufficed for qualification, subject to the NIRC’s requirements.

Statutory Framework

Sec. 108(B)(7), NIRC classifies the sale of power or fuel generated through renewable sources of energy as subject to the zero percent VAT rate.
Sec. 112(A), NIRC, prescribes the two-year prescriptive period and the conditions under which VAT-registered persons engaged in zero-rated sales may apply for tax credit certificate or refund of creditable input tax attributable to such sales.
Republic Act No. 9513 (2008), Section 15(g), grants VAT zero-rating and Section 25–26 govern DOE certification with Section 26 stating DOE certifications are "without prejudice to any further requirements" by administering agencies.

The DOE later amended its IRR by DOE Department Circular No. DC2021-12-0042 (2021) to remove the per-transaction Certificate of Endorsement requirement for most incentives, except duty-free importation.
The BIR's RR No. 7-2022 implements tax provisions of RA 9513 and clarifies documentary requirements for availment of incentives.
