Income Tax - Addition Modifications - Business Stock Gains, Fines, Penalties, and Bonus Depreciation

HB 801 modifies Maryland's income tax rules by requiring taxpayers to add back certain amounts excluded from federal income tax. Specifically, it adds back gains from qualified small business stock sales (excluded under federal law) and fines/penalties exceeding $50,000 that were deducted as business expenses (excluding taxes paid for violations). The bill also adjusts depreciation calculations for businesses, particularly removing special treatment for manufacturing entities placing property in service after 2018. These changes directly affect Maryland businesses and individuals with qualifying stock sales, significant compliance costs, or specific depreciation deductions.
