Retiring in Maine means three different rules apply to three common income streams. Social Security is completely exempt, pension and retirement-account income gets a deduction, and only what remains is taxed at Maine’s ordinary rates. This calculator applies each rule so you can see your real Maine bill.
How it works
Maine starts by removing Social Security benefits, which are never taxed at the state level. It then allows a pension income deduction — up to 30,000 dollars per recipient in 2024 — against eligible pension, annuity, and retirement-plan income such as 401(k) and IRA withdrawals. That deduction is reduced by the Social Security you received, because those benefits are already tax-free:
pension deduction = max(0, cap - social_security_received)
taxable retirement = max(0, pension + ira_401k - pension_deduction)
The remaining taxable amount is taxed at Maine’s graduated rates of 5.8, 6.75, and 7.15 percent.
Example
A single retiree with 24,000 dollars of Social Security, a 28,000 dollar pension, and 10,000 dollars of IRA withdrawals pays no Maine tax on the Social Security. The pension deduction is 30,000 minus 24,000, or 6,000 dollars, so taxable retirement income is 28,000 plus 10,000 minus 6,000, or 32,000 dollars, taxed at Maine’s lower brackets.
Notes
This is a simplified estimate. It does not model Maine’s standard deduction, personal exemptions, the deduction phase-out at very high income, or military pension rules. Confirm specifics with the current Maine Schedule 1S instructions at maine.gov/revenue before filing.
