Income Tax - Addition Modifications - Excluded Opportunity Fund Gains, Foreign-Derived Deduction Eligible Income, and Interest

HB 1080 modifies Maryland's income tax code to align with recent federal changes. It adds three specific types of income to Maryland taxable income: capital gains from qualified opportunity funds (previously excluded federally), certain foreign business income, and interest excluded under federal law. This affects Maryland taxpayers and corporations that earn these specific income types, requiring them to include these amounts in their state tax calculations. The changes take effect for taxable years beginning after December 31, 2025, with the full implementation starting July 1, 2026.
