VAT Refund Claims: Proving Input Tax Payments With Proper Documentation

The Supreme Court’s 2005 ruling in Commissioner of Internal Revenue v. Manila Mining Corporation (G.R. No. 153204) clarifies a crucial point for businesses seeking VAT refunds or tax credit certificates: the claim must be supported by proper documentary evidence, not just summaries or certifications. This decision serves as a reminder that even valid tax refund claims can be denied for failure to comply with evidentiary rules.

The Case: Manila Mining’s Claim for Input VAT Refund

Manila Mining Corporation, a VAT-registered mining company, sold gold to the Central Bank (now Bangko Sentral ng Pilipinas) in 1991. Under BIR rulings, such sales were considered export sales subject to zero-rated VAT. Since the company charged no output VAT on these sales, it sought to recover the input VAT it had paid on its purchases.

The company filed applications for refund or tax credit with the Bureau of Internal Revenue (BIR) covering its input VAT payments for the four quarters of 1991, totaling over P13.8 million. When the BIR failed to act on the applications within the 60-day period, Manila Mining filed petitions before the Court of Tax Appeals (CTA).

The Issue: Sufficiency of Evidence

The central question was whether Manila Mining had adduced sufficient evidence to prove its claim for refund of input VAT. The company argued that it had submitted the necessary documents to the BIR and that certain admissions by the Commissioner of Internal Revenue (CIR) relieved it of the burden of presenting purchase invoices and receipts before the CTA.

The Ruling: Documentation Is Essential

The Supreme Court ruled against Manila Mining, reinstating the CTA’s denial of the refund claims. The Court held that a taxpayer claiming a refund must substantiate the input VAT paid with purchase invoices or official receipts. Mere summaries or schedules of invoices, even when certified by an independent CPA, are not enough.

Key Principles Established

1. Burden of proof lies with the taxpayer. A claim for refund is in the nature of a claim for exemption and is construed strictly against the taxpayer. The taxpayer must prove every minute aspect of its claim.

2. Documents must be formally offered in evidence. The CTA is a court of record, and cases before it are litigated de novo. Documents submitted to the BIR have no evidentiary value unless formally offered before the CTA. Under the Rules of Court, the court shall consider no evidence that has not been formally offered.

3. CPA certifications have limits. While CTA Circulars allow summaries and CPA certifications for voluminous documents, they do not eliminate the requirement to present the underlying documents. The circulars require that photocopies of invoices and receipts be pre-marked and submitted to the court so the adverse party can verify them. Originals must be available for comparison if authenticity is questioned.

4. Requests for admission have limits. The Court rejected Manila Mining’s argument that the CIR’s failure to file a sworn reply to its request for admission constituted an implied admission of the amounts claimed. The matters requested were mere reiterations of allegations already denied in the CIR’s Answers. Admissions as a mode of discovery are meant to clarify issues, not to reproduce what has already been pleaded.

5. VAT invoices are required. Under the invoicing requirements of the implementing regulations for the VAT system, only purchases covered by VAT invoices are entitled to input tax credits. The CTA must be able to examine the invoices to confirm they are proper VAT invoices. (Note: The specific revenue regulation number cited in the decision is not available in the ASG law library.)

Practical Takeaways

• Keep your VAT invoices and receipts organized and accessible. These are the primary evidence needed to support any claim for input VAT refund or credit.
• Do not rely solely on summaries or CPA certifications. While these can help present voluminous documents efficiently, the underlying invoices and receipts must be pre-marked and submitted to the CTA.
• File claims within the prescriptive period. Applications for refund of input VAT must be filed within two years from the close of the quarter when the zero-rated transaction took place.
• Be prepared for a full trial before the CTA. Cases are heard de novo, meaning you must present your evidence again, regardless of what was previously submitted to the BIR.
• When using requests for admission, focus on genuinely disputed facts. Do not use them to reiterate matters already denied in the pleadings.
