G.R. No. 172378 ; January 17, 2011
SILICON PHILIPPINES, INC. (Formerly INTEL PHILIPPINES MANUFACTURING, INC.), Petitioner, vs. COMMISSIONER OF INTERNAL REVENUE, Respondent.

FACTS

Petitioner Silicon Philippines, Inc., a BOI-registered pioneer enterprise engaged in designing, developing, manufacturing, and exporting integrated circuits, filed an application for credit/refund of unutilized input VAT for the period October 1 to December 31, 1998, in the amount of ₱31,902,507.50. This amount comprised ₱15,170,082.00 for input VAT on imported/locally purchased capital equipment and ₱16,732,425.50 for input VAT on other purchases. Due to the inaction of the respondent Commissioner of Internal Revenue (CIR), petitioner filed a Petition for Review with the Court of Tax Appeals (CTA) Division. Petitioner alleged it had zero-rated export sales of ₱3,027,880,818.42 for the period and paid the aforementioned input VAT, which was not applied to any output VAT. The CIR, in his Answer, raised defenses including that the petition stated no cause of action for failing to allege payment dates, that claims for refund are construed strictly against the claimant, and that the burden of proof lies with the taxpayer.
The CTA Division partially granted the petition. It allowed a refund of ₱9,898,867.00 out of the ₱15,170,082.00 claim for input VAT on capital goods, disallowing the portion attributable to items not considered capital goods under relevant regulations. However, it denied the ₱16,732,425.50 claim for input VAT attributable to zero-rated export sales. The denial was based on petitioner’s failure to present an Authority to Print (ATP) from the BIR for its sales invoices and its failure to print the ATP number and the word “zero-rated” on its export sales invoices, as required by law and regulations. Petitioner moved for reconsideration, arguing it had a “Permit to Adopt Computerized Accounting Documents” and that printing “zero-rated” was unnecessary since its sales were to a non-resident, non-VAT registered entity. The CTA Division denied the motions, noting petitioner’s permit for computerized invoices was issued only in 2001, long after the taxable period in question (1998), rendering the invoices issued in 1998 without proper authority and inadmissible as evidence.
Petitioner elevated the case to the CTA En Banc, which denied the petition. The CTA En Banc upheld the Division’s ruling, emphasizing that printing the ATP on invoices is a mandatory control mechanism under Section 238 of the Tax Code. It also ruled that printing the word “zero-rated” on invoices for zero-rated transactions is expressly required by Revenue Regulations No. 7-95. The failure to comply with these formal invoicing requirements was fatal to petitioner’s claim for refund of input VAT on its zero-rated sales.

ISSUE

Whether petitioner is entitled to a refund or credit of input VAT attributable to its zero-rated export sales for the fourth quarter of 1998.

RULING

No. The Supreme Court denied the petition and affirmed the rulings of the CTA Division and the CTA En Banc. The Court held that the burden of proving entitlement to a tax refund lies with the claimant, and such claims are construed strictly against the taxpayer as they are in the nature of tax exemptions. To substantiate a claim for refund of input VAT on zero-rated sales, a taxpayer must prove not only the substantive requirement of being engaged in zero-rated sales but also compliance with the attendant administrative or documentary requirements.
The Court ruled that petitioner failed to comply with the mandatory invoicing requirements. First, under Section 238 of the National Internal Revenue Code (NIRC) and Section 4.108-1 of Revenue Regulations No. 7-95, all VAT-registered persons must issue duly registered invoices or receipts. The Authority to Print (ATP) is a prerequisite for printing such invoices, and the ATP number must be printed on the invoice itself. Petitioner’s “Permit to Adopt Computerized Accounting Documents” was issued only in 2001 and did not cover the 1998 period. The sales invoices presented for the 1998 transactions, lacking the required ATP, were therefore invalid for VAT purposes and could not prove the claimed zero-rated sales.
Second, the law and regulations explicitly require that the word “zero-rated” be printed on the invoice covering zero-rated transactions. Petitioner’s argument that this was unnecessary because its buyer was a non-resident was rejected. The requirement is absolute and not dependent on the buyer’s status. Failure to print “zero-rated” on the invoices means the sales are not considered zero-rated for VAT purposes, disqualifying the related input VAT from being refunded.
Since petitioner did not present valid VAT invoices or receipts for its alleged zero-rated sales—as the documents lacked the ATP and the “zero-rated” marking—it failed to discharge its burden of proof. Consequently, it is not entitled to the refund of input VAT amounting to ₱16,732,425.50 attributable to those sales. The Court upheld the refund of ₱9,898,867.00 for input VAT on capital goods as this portion was not contested in the petition before the Supreme Court.
