How Maine taxes retirement income
Maine does not tax Social Security benefits. Pensions and 401(k)/IRA withdrawals are partly taxed (there is an exclusion, then the rest is taxed). Social Security and Railroad Retirement benefits are fully exempt from Maine income tax regardless of income level. Separately, Maine allows a 'pension income deduction' (up to $49,824 per person for tax year 2026, indexed annually to the federal maximum Social Security benefit at full retirement age under 42 U.S.C. 416(l)) against qualifying retirement income, which explicitly includes state/federal/private pensions AND 401(k)/403(b)/other employer-plan and IRA (including Roth and SIMPLE IRA) withdrawals. Two limits cut against full exemption: (1) the deduction must be reduced dollar-for-dollar by any Social Security/Railroad Retirement benefits received (so someone already drawing near-max Social Security gets little or no additional pension deduction), and (2) for tax years beginning on or after January 1, 2025, the deduction phases out entirely once federal AGI exceeds $125,000 (single or married filing separately), $187,500 (head of household), or $250,000 (married filing jointly/surviving spouse), thresholds indexed for inflation after 2025. Military retirement pay is separately and fully exempt regardless of income (36 M.R.S. 5122(2)(M-2)). Net effect: pension and 401(k)/IRA withdrawals are only PARTIALLY sheltered (up to the capped, SS-offset, income-phased-out deduction), not fully exempt and not fully taxed, hence 'partial' rather than true/false for both.
