Maine does tax pensions, but a large deduction shields most retirees from paying much on them. For tax year 2026, each retiree can subtract up to $49,824 of qualifying pension and retirement income from Maine taxable income, and a married couple filing jointly can subtract up to $99,648 combined. Social Security is fully exempt on top of that, and military retirement pay is exempt without any cap.
The catch is that the deduction is reduced dollar-for-dollar by any Social Security you receive, and higher-income retirees now face a phaseout. Here is how the pieces fit together.
Social Security Is Not Taxed at All
Maine does not tax Social Security benefits, regardless of your income level or filing status. You do not claim a deduction or fill out a worksheet to exclude it. It simply never enters the Maine tax base.
That said, Social Security still shapes your Maine tax picture, because the amount you receive directly reduces the pension deduction you can claim on other retirement income.
The Pension Income Deduction
Maine’s income tax starts with your federal adjusted gross income. Any pension, annuity, 401(k) distribution, or IRA withdrawal that is taxable federally is initially included in your Maine income too. The pension income deduction is what carves most of it back out.
For 2026, the maximum deduction is $49,824 per person, tied to the maximum annual Social Security benefit payable at full retirement age that year. Each spouse on a joint return calculates the deduction independently, so a couple can potentially deduct up to $99,648 combined.
The Social Security Offset
Before you apply the deduction to your pension or IRA income, you must reduce the $49,824 ceiling by your total Social Security and Railroad Retirement benefits received during the year. Both the taxable and nontaxable portions count. If your Social Security benefits equal or exceed $49,824, the deduction zeroes out and you get no additional subtraction for other retirement income.
A worked example. A single retiree in 2026 receives $22,000 in Social Security and $40,000 from a state pension:
- Maximum deduction: $49,824
- Minus Social Security received: $22,000
- Remaining deduction available: $27,824
- Pension income: $40,000
- Deduction claimed: $27,824 (the lesser of the remaining deduction and the pension income)
- Pension income subject to Maine tax: $12,176
Only $12,176 of the $40,000 pension ends up taxable in Maine. A retiree with a larger Social Security check would have a smaller remaining deduction; a retiree with no Social Security at all could shelter up to the full $49,824 of pension income.
Phaseout for Higher-Income Retirees
Starting with tax year 2025, higher-income retirees lose part or all of the non-military portion of the deduction. The phaseout begins at these federal AGI thresholds:
- Single or married filing separately: $125,000
- Head of household: $187,500
- Married filing jointly or surviving spouse: $250,000
To calculate the reduction, divide the amount your AGI exceeds the threshold by $100,000 ($50,000 if married filing separately). That ratio, capped at 1.00, is multiplied by your otherwise-allowable deduction to determine how much you lose. A single filer with $175,000 of AGI in 2025 loses half the deduction. At $225,000 or more, the entire non-military deduction disappears. Threshold amounts are indexed for inflation for tax years beginning in 2026 and later.
Which Retirement Income Qualifies
The deduction covers a broad range of retirement sources. Qualifying employer-sponsored plans include:
- Qualified pension and profit-sharing plans under IRC Section 401(a), including 401(k) plans
- Employee annuity plans under IRC Section 403, including 403(b) plans
- Eligible deferred compensation plans from state and local governments under IRC Section 457(b)
- Federal, state, and military retirement plans
Individual retirement accounts also qualify, including traditional IRAs, SEP-IRAs, SIMPLE IRAs, and Roth IRAs. In practice, the deduction matters most for traditional IRA and employer plan distributions, because those are the ones typically taxable on your federal return. Qualified Roth withdrawals are already federally tax-free, so there is usually no Maine-taxable amount to deduct.
Several things do not qualify:
- Early distributions from employer plans before age 55 that are not part of a series of substantially equal periodic payments over your lifetime or the joint lives of you and your beneficiary. The age threshold does not apply to IRA distributions.
- Disability income reported as wages on your federal return rather than as pension income.
- Conversions between accounts, such as rolling a traditional IRA into a Roth IRA. The taxable conversion amount does not count as a retirement benefit for this deduction.
The deduction goes to the person whose work generated the benefit, or to a surviving spouse receiving survivor benefits from that person’s plan.
Military Retirement Pay Is Fully Exempt
Military retirement benefits are completely exempt from Maine income tax. No cap, no Social Security offset, and no income-based phaseout. The full amount of military retirement pay included in your federal AGI is subtracted from Maine income.
For tax years beginning in 2026, Maine expanded the definition of military retirement to cover benefits from all uniformed services of the United States. That now includes retirement pay from the commissioned corps of the National Oceanic and Atmospheric Administration and the Public Health Service, in addition to the traditional branches and Space Force.
If You Split Time Between Maine and Another State
Full-time Maine residents pay Maine tax on retirement income from all sources, whether the pension comes from a Maine employer, an out-of-state company, or a federal system. If another state also taxes the same income, a Maine resident can claim a credit on their Maine return to avoid double taxation.
Snowbirds need to watch Maine’s statutory residency rule carefully. Even if you claim Florida or another no-income-tax state as your domicile, Maine can still tax you as a resident if you maintain a permanent home there. To avoid that outcome, you must be able to document that you were physically present outside Maine for more than 183 days during the tax year. Maine Revenue Services expects records such as calendars, travel receipts, plane tickets, and credit card statements to support the claim.
Claiming the Deduction on Your Return
The pension income deduction is reported as a subtraction on Schedule 1S (Income Modifications) of Maine Form 1040ME. Before entering an amount on Schedule 1S, work through the Pension Income Deduction Worksheet in the Form 1040ME instructions. The worksheet walks through the maximum deduction, the Social Security offset, and, if applicable, the phaseout. File the completed worksheet with your return.
Military retirement pay has its own line on Schedule 1S, separate from the general pension deduction. If you receive both military retirement and a civilian pension, claim the military exemption in full on one line, then calculate the civilian pension deduction (with the Social Security offset) on the other.
