In Commissioner of Internal Revenue v. Semirara Mining Corporation, the Supreme Court affirmed that Semirara Mining Corporation (SMC) is exempt from value-added tax (VAT) on its sales of coal to the National Power Corporation (NPC). This ruling upholds the incentives granted to coal operators under Presidential Decree (PD) No. 972, a special law designed to encourage the exploration and utilization of the country’s coal resources. This decision clarifies the interplay between special laws and general tax legislation, ensuring that specific incentives remain valid unless expressly repealed, thus providing stability for businesses operating under such incentives.

Mining Rights and Tax Shields: How a Special Law Protects Coal Sales from VAT

This case revolves around the tax liabilities of Semirara Mining Corporation (SMC), a company engaged in coal exploration and sales, specifically concerning Value Added Tax (VAT) on its sales to the National Power Corporation (NPC). SMC operates under a Coal Operating Contract (COC) with the Philippine government, initially established with the Energy Development Board under Presidential Decree (PD) No. 972. PD No. 972 aims to incentivize the coal industry by offering various tax exemptions to operators. Section 16 of PD No. 972 explicitly grants operators an exemption from all taxes except income tax.

The COC between SMC and the government incorporated this provision, stating:

“Section V. Rights and Obligations of the Parties

. . .

5.2 .The OPERATOR shall have the following rights:

a) Exemption from all taxes (national and local) except income tax… “

Following amendments to the National Internal Revenue Code (NIRC) by Republic Act (R.A.) No. 9337, NPC began withholding 5% final VAT on SMC’s coal billings, leading SMC to seek clarification from the Bureau of Internal Revenue (BIR). The CIR issued BIR Ruling No. 0006-2007, confirming SMC’s VAT exemption, however, SMC still pursued a refund for the VAT already withheld. After the BIR’s inaction, SMC filed a petition with the Court of Tax Appeals (CTA) seeking a refund of P15,292,054.93 representing the final VAT withheld on its coal sales for January 2007.

The CTA Division sided with SMC, ordering the CIR to refund or issue a tax credit certificate for the amount claimed. The CTA Division based its decision on Section 109(K) of the NIRC of 1997, as amended, in conjunction with Section 16 of PD No. 972, affirming the VAT-exempt status of SMC’s coal sales. The CIR appealed to the CTA En Banc, which upheld the Division’s decision, stating that the petition was a mere rehash of previous arguments and that SMC’s VAT exemption was clear under PD 972. The CIR then elevated the case to the Supreme Court.

At the heart of the Supreme Court’s analysis was whether the enactment of R.A. No. 9337, which amended the NIRC, effectively repealed the VAT exemption granted to SMC under PD No. 972. The court referenced the principle that a special law, like PD No. 972, is not repealed or modified by a subsequently enacted general law (R.A. No. 9337) unless there is an express provision to that effect. The repealing clause of R.A. No. 9337 did not explicitly mention PD No. 972, suggesting that Congress did not intend to revoke the tax exemptions provided therein.

The court emphasized that Section 109(K) of R.A. No. 9337 recognized transactions exempt under special laws:

“SEC. 109. Exempt Transactions. — (1) Subject to the provisions of Subsection (2) hereof, the following transactions shall be exempt from the value-added tax: x x x x

K) Transactions which are exempt under international agreements to which the Philippines is a signatory or under special laws, except those under Presidential Decree No. 529; (Emphasis and underscoring supplied)”

This provision, according to the Court, explicitly preserves the VAT exemption granted to SMC under PD No. 972, a special law designed to promote the coal industry. The court also cited its previous ruling in CIR v. Semirara Mining Corp. which involved similar facts and issues, reinforcing the principle that PD No. 972 was not impliedly repealed by R.A. No. 9337.

The Supreme Court reiterated the principle against unjust enrichment, stating that the government should not invoke technicalities to retain money that rightfully belongs to the taxpayer. The court underscored that SMC’s claim for a tax refund was expressly granted by law and not based on estoppel. It also found no merit in the CIR’s argument that SMC’s judicial claim was premature for failing to exhaust administrative remedies, given the CIR’s inaction on SMC’s claim for two years. Furthermore, the Court acknowledged the expertise of the CTA in resolving tax matters and found no reversible error in its decision.
