General Mills, Inc. v. Commissioner of Revenue

General Mills, a Delaware corporation headquartered in Minnesota with its principal research and development facilities in the state, claimed a Minnesota research and development tax credit of $1,112,772 on its timely 2011 corporate franchise tax return. In 2015, the company filed an amended return recalculating the credit in two respects — omitting the federal 'minimum base amount' limitation and substituting federal (rather than Minnesota-only) 'aggregate gross receipts' in the fixed-base-percentage formula — and sought an additional refund of $949,236 plus interest. The Commissioner denied the refund, and the Minnesota Tax Court granted summary judgment resolving both issues on cross-motions, leading to consolidated review by the Minnesota Supreme Court together with a companion case, International Business Machines Corp. v. Commissioner of Revenue.

The Minimum Base Amount Survives Incorporation

Minnesota's research credit statute defines 'base amount' as the term is 'defined in section 41(c) of the Internal Revenue Code.' The Court found this language ambiguous — it could refer narrowly to only the paragraph of IRC section 41(c) that states what 'base amount' means, or broadly to the whole subsection, including its 'minimum base amount' floor. Tracing the statute's legislative history back to 1982, when Minnesota first incorporated the federal 'base period research expenses' concept (which itself included an analogous 50%-of-QRE floor), the Court concluded the Legislature intended to incorporate the minimum base amount limitation along with the rest of the base-amount calculation mechanics, since provisions unrelated to that calculation (like the alternative incremental and simplified credit elections) were added to the federal code only years after Minnesota's incorporating statute was written.

'Aggregate Gross Receipts' Retained Its Federal, Worldwide Meaning

The Court held that because the Legislature expressly limited other components of the base-amount formula to Minnesota-only amounts but left the term 'aggregate gross receipts' unmodified, that term retained its federal meaning — worldwide gross receipts — under Treasury Regulation section 1.41-3(c). The Court rejected the Commissioner's argument that this would create an internal inconsistency by giving 'gross receipts' two different geographic meanings within the same formula, holding that courts cannot rewrite unambiguous statutory text to serve a perceived policy purpose. Using the larger, federal gross-receipts figure as the formula's denominator produces a smaller base amount and, correspondingly, a larger available credit.

Because the parties had stipulated that General Mills would be entitled to only its originally-claimed credit amount if it prevailed on the aggregate-gross-receipts issue but not the minimum-base-amount issue — which is exactly what happened — the Court's ruling meant General Mills was not entitled to any additional refund beyond the $1,112,772 already allowed.

Significance: Issued alongside its companion IBM decision, this opinion is the controlling Minnesota Supreme Court authority on how the state's research credit base-amount formula incorporates federal IRC section 41(c) mechanics, an issue the Legislature only partially addressed through a non-retroactive 2017 amendment.
