Corporate franchise tax; certain foreign corporations treated as unitary.

HF 1533 amends Minnesota's corporate franchise tax laws to treat certain foreign corporations operating in Minnesota as "unitary" businesses. It directly affects foreign corporations that meet the new definition of a "tax haven" (e.g., jurisdictions with opaque tax regimes, preferential treatment for foreign entities, or favorable tax avoidance structures). The bill adds definitions for "tax haven" and requires corporations with significant business in such jurisdictions to have their worldwide income apportioned and taxed under Minnesota's unitary tax rules, rather than just income generated within the state. Key provisions include aligning Minnesota tax deductions with federal "Global intangible low-taxed income" (section 951A) and "Subpart F income" rules. The changes take effect for taxable years beginning after December 31, 2025.
