Decision Date

Philex Mining sought a VAT refund for zero-rated sales; CIR denied due to lack of subsidiary journals. SC ruled in favor, stating such documents aren’t mandatory for refund claims under the Tax Code.

Case Summary (G.R. No. 230016)

Facts and Procedural Background

Philex Mining, as a VAT-registered exporter, filed amended quarterly VAT returns in 2012 reflecting excess input VAT from zero-rated sales to several foreign buyers. It subsequently filed administrative claims for refund with the Department of Finance’s One-Stop Shop Center (DOF-OSS) and later filed petitions for review before the CTA. After consolidation of cases and the appointment of an Independent Certified Public Accountant (ICPA) to examine the claim, the CTA Division partly granted the refund claim, ordering CIR to pay P51,734,898.99 representing unutilized input VAT for the relevant quarters.

The CIR moved for reconsideration, arguing the claim was premature, procedural requirements such as submission of specific checklists were not met, and crucially, that Philex Mining failed to comply with accounting requirements, specifically maintaining subsidiary sales and purchase journals and filing monthly VAT declarations. The CTA Division denied the motion, reaffirming that such accounting compliance was not a legal prerequisite for refund entitlement. The CIR appealed to the CTA En Banc, which upheld the Division’s ruling. The CIR then elevated the case to the Supreme Court.

Applicable Law and Legal Issue

The case is governed by the 1987 Philippine Constitution and pertinent provisions of the National Internal Revenue Code (NIRC) as amended, particularly Sections 106, 110, 112, 113, 114, and 237, and the implementing Revenue Regulations (RR) No.16-2005. The central legal issue concerns whether maintaining subsidiary journals and filing monthly VAT returns are mandatory conditions precedent for a taxpayer to claim refund or tax credit of unutilized input VAT attributable to zero-rated sales.

Philex Mining contends, and the CTA ruled, that these are not among the documentary or procedural requirements prescribed by law for refund claims. The CIR insists such compliance is essential for substantiating the input VAT claim, as provided under RR 16-2005.

Supreme Court’s Ruling on Statutory Interpretation

The Court emphasized the canonical rules of statutory construction under the 1987 Constitution: clear, unambiguous statutory language must be given its literal meaning without adding conditions not provided by law. The Court found that neither the NIRC nor RR No. 16-2005 explicitly require the taxpayer to produce subsidiary sales and purchase journals or monthly VAT declarations as conditions to entitlement to refund or tax credit.

The Court referred to Section 112(A) of the NIRC, which specifies conditions for VAT refund on zero-rated sales. While these include VAT registration, zero-rated sales status, timely filing within two years, attribution of input tax to zero-rated sales, and accounting of foreign exchange proceeds, no provision mandates maintenance of subsidiary journals or filing of monthly declarations as prerequisites.

Substantiation Requirements Under Tax Code and Revenue Regulations

The Court clarified that under Section 110(A) and related provisions (Sections 113 and 237) of the NIRC, the primary evidentiary requirements to support input VAT claims are valid VAT invoices or official receipts that meet formal invoicing criteria, such as indicating the seller’s VAT registration, Taxpayer Identification Number (TIN), and the phrase "zero-rated sale" where applicable.

Revenue Regulations and jurisprudence consistently hold that failure to comply with invoicing standards is a valid ground for denial of input VAT claims due to the lack of credible evidence of input tax. However, the Court distinguished these invoicing requirements from accounting books such as subsidiary journals, noting that subsidiary journals serve more as internal records and not as direct evidence of input VAT eligibility.

Subsidiary Journals and Monthly VAT Declarations: Not Mandatory for Refund Claims

The Court explained that subsidiary sales and purchase journals are bookkeeping aids, and while their maintenance may be required under Section 4.113-3 of RR No. 16-2005, the law does not condition refund claims upon their submission or existence. Similarly, monthly VAT declarations, while required under Section 114 and related regulations for payment and monitoring of VAT, do not legally bar refund claims if not timely filed, provided the VAT has in fact been paid.

The Court contrasted this case with Taganito Mining Corporation, where the failure to present subsidiary ledgers related to capital goods purchases was fatal due to specific amortization requirements under the NIRC and corresponding regulations. In the instant case involving non-capital goods and services, such detailed subsidiary ledgers are not indispensable.

Jurisprudential Precedents Cited and Distinctions

The Court reaffirmed prior decisions (Western Mindanao Power Corp., Bonifacio Water Corp., Sitel Phils. Corp.) requiring compliance with invoicing and accounting regulations, emphasizing that these cases dealt specifically with invoicing defects, not non-maintenance of subsidiary journals or non-filing of monthly returns. The Court identified t
