An Act To Bring Fairness In Income Taxes To Maine Families By Adjusting The Tax Brackets And Tax Rates

LD 229 adjusts Maine's individual income tax brackets and rates for tax years beginning in 2026, replacing the existing 2017-2025 brackets. It affects three filing statuses: single individuals (and married filing separately), heads of households, and married couples filing jointly. For 2026, the bill increases income thresholds for each tax bracket (e.g., the lowest bracket for single filers rises from under $21,050 to under $41,600) and modifies rates, including raising the top rate to 8.2% for incomes over $500,000 for single filers. The changes apply to all Maine taxpayers in these filing categories starting January 1, 2026.
