Title
Commissioner of Internal Revenue vs. Court of Appeals
Case
G.R. No. 107135
Decision Date
Feb 23, 1999
CIR challenged tax rulings favoring CENVOCO, disputing whether sales tax on containers could offset miller's tax; Supreme Court affirmed exceptions did not apply.

Case Summary (G.R. No. 107135)

Undisputed Facts

CENVOCO manufactures edible coconut oil and copra meal subject to the miller’s tax (3%) and also manufactures products subject to sales tax (10%). In 1986 CENVOCO purchased containers and packaging materials (e.g., tin cans, tetra-paks) for its refined edible oil and paid sales tax on those purchases. A Revenue Examiner’s investigation led to Assessment Notice No. FAS-B-86-88-001661-001664 (April 22, 1988) assessing a deficiency miller’s tax of P1,575,514.70 for 1986. CENVOCO sought reconsideration (letters dated June 27, 1988 and September 28, 1988). By letter of November 17, 1988 Deputy Commissioner Santos reiterated the assessment and denied the requested credit.

Procedural History

CENVOCO filed a petition with the Court of Tax Appeals. The CTA rendered judgment on December 3, 1990, holding CENVOCO not liable for the alleged deficiency miller’s tax. The Court of Appeals affirmed the CTA decision in toto. The Commissioner of Internal Revenue petitioned the Supreme Court for review on certiorari.

Issue Presented

Whether the sales taxes paid by CENVOCO on containers and packaging materials for its milled products may be credited against the assessed deficiency miller’s tax under the final proviso of Section 168 of the NIRC, which disallows credit “for any sales, miller’s or excise taxes paid on raw materials or supplies used in the milling process.”

Applicable Law (Section 168, NIRC) and Interpretive Rules

Section 168 imposes a percentage (miller’s) tax on proprietors or operators of specified mills and includes a final proviso disallowing credit for taxes paid on “raw materials or supplies used in the milling process.” Revenue regulations cited define “raw materials” as articles that, when used in manufacture, become a homogenous part of the finished article and cannot be identified in their original state. Rules of statutory construction applied include that exceptions are to be strictly but reasonably construed and that words of a statute should ordinarily be given their plain, common meaning. The Court also invoked established principles that tax statutes are construed strictly against the government and that quasi‑judicial agencies such as the CTA merit respect for their expertise unless there is abuse.

CTA and Court of Appeals Reasoning — Characterization of Containers and Packaging

Both the CTA and the Court of Appeals concluded that containers and packaging materials (cans, tetrapaks) are not “raw materials” used in the milling process. The courts relied on (a) the ordinary and regulatory definition of “raw materials” as materials that merge into the product and cannot be separately identified; (b) the practical observation that containers are not fed into milling machinery nor converted into the finished edible oil; (c) dictionary and prior case definitions distinguishing packaging/containers from raw materials; and (d) the statutory context of Section 168, which limits the miller’s tax to specified milled products and their by-products. On that basis the CTA and CA held the sales taxes paid on containers and packaging were not barred by the proviso and therefore could be credited against the miller’s tax.

Commissioner’s Arguments and Non-Retroactivity Concern

The Commissioner argued the final proviso of Section 168 prohibits the claimed credit and relied on a different BIR ruling by Commissioner Ruben Ancheta in October 1984 that had allowed a similar credit to CENVOCO, asserting that reversal would conflict with the non-retroactivity rule for tax rulings (Section 278 of the old Tax Code) and would impermissibly create a perpetual exemption for CENVOCO. The CA addressed this contention but did not find the existence of an improvident or abusive exercise that would require overturning the CTA’s application of the statutory text.

Supreme Court Analysis — Statutory Construction and Policy Considerations

The Supreme Court applied strict but reasonable construction of the proviso, emphasizing that the disallowance expressly refers only to taxes paid on raw materials or supplies used in the milling process. The Court observed that exceptions to general statutory rules must not be extended by implication and that ambiguous or doubtful exceptions should be resolved in favor of the general provision. Given the regulatory and ordinary meanings of “raw materials,” the Court found that containers and packaging fall outside the proviso’s scope. The Court
