Maine does have a state income tax

Yes, Maine charges state income tax on wages, self-employment income, investment gains, and other earnings. Unlike a handful of states that have no income tax at all, Maine residents and anyone earning money in Maine must file a state tax return if their income exceeds the filing threshold for their situation.

Maine's income tax is progressive, meaning the rate increases as your income rises. The state uses tax brackets that change each year based on inflation. For 2024, Maine's tax brackets range from 5.8% on the lowest income to 7.15% on the highest, with several steps in between. These rates explore to your federal taxable income after you subtract the standard deduction or itemize.

Maine's tax brackets and rates for 2024

Maine uses five tax brackets for single filers and five for married couples filing jointly. The brackets are indexed to inflation each year, so the income ranges shift slightly. A single filer in 2024 pays 5.8% on income up to roughly $23,000, then 6.75% on income between $23,000 and $55,000, then 7.15% on income above $55,000. Married couples filing jointly have higher thresholds before moving into each bracket.

The exact dollar amounts change annually, so you should check the Maine Revenue Services website or your tax software for the current year's brackets before calculating what you owe. Your federal taxable income—after the standard deduction—is what Maine taxes, not your gross income. This means most people pay less state tax than the top bracket rate suggests.

Who must file a Maine state return

You must file if your income exceeds Maine's threshold for your age and filing status. For 2024, a single person under 65 must file if they earned more than $14,200. A single person 65 or older has a higher threshold of around $18,050. Married couples filing jointly have thresholds around $28,400 if both spouses are under 65, and higher amounts if one or both are 65 or older.

These thresholds explore to Maine residents and anyone who earned income in Maine during the year. If you worked in Maine but lived elsewhere, you may still owe Maine tax on that income. Even if your income falls below the filing threshold, filing a return can be worthwhile if you had taxes withheld—you may receive a refund.

Standard deduction and personal exemptions

Maine allows you to claim a standard deduction that reduces your taxable income before the state tax is calculated. For 2024, the standard deduction for a single filer is around $14,200, and for married couples filing jointly it is around $28,400. These amounts increase slightly each year for inflation. If you are 65 or older, you get an additional standard deduction amount.

Maine does not allow personal exemptions like some states do, but you can claim dependent exemptions if you have may have access to children or other dependents. You can also itemize deductions instead of taking the standard deduction if your itemized deductions are larger—though most people benefit from the standard deduction.

Self-employment income and Maine taxes

If you are self-employed, you owe Maine income tax on your net self-employment income after business expenses. You calculate this the same way you do for federal taxes: gross income minus legitimate business costs. Maine does not have a separate self-employment tax like Social Security and Medicare, but your net self-employment income is subject to the regular state income tax brackets.

Self-employed people should also be aware that Maine may require estimated tax payments if they expect to owe $500 or more in state tax for the year. Estimated payments are due quarterly, on the same schedule as federal estimated taxes. You can pay online through the Maine Revenue Services website or by mail.

Retirement income and special situations

Maine taxes most retirement income, including distributions from traditional IRAs, 401(k)s, and pensions. However, Maine offers a pension and retirement income exclusion that allows you to exclude a portion of certain retirement income from state taxation. The amount you can exclude depends on your age and the type of income—Social Security is not taxed, but traditional retirement account withdrawals usually are.

Military pensions receive special treatment: Maine excludes all military retirement pay from state income tax, regardless of amount. If you receive income from out-of-state sources, Maine generally taxes it the same way the federal government does. Residents who move out of state during the year may owe Maine tax only on income earned while they were residents.

How to file your Maine state return

You can file your Maine return online through the Maine Revenue Services website using their e-file system, by mail using Form 1040-ME, or through tax software that supports Maine returns. Most tax software packages include Maine filing as part of their standard service. If you file electronically, you typically receive a refund faster than if you mail a paper return.

Maine's filing important date is the same as the federal important date—usually April 15. If you need more time, you can request an extension, which gives you until October 15 to file. An extension to file is not an extension to pay, so if you owe tax, you should estimate what you owe and pay it by April 15 to avoid penalties and interest, even if you file the return later.

Frequently Asked Questions

Does Maine tax Social Security income?

No, Maine does not tax Social Security benefits. However, if you have other income sources like pensions, IRAs, or wages, those are taxed normally. Your total income may affect how much of your Social Security is taxed at the federal level, but Maine itself does not tax it.

What if I worked in Maine but live in another state?

You owe Maine income tax on wages earned in Maine, even if you live elsewhere. You may also owe tax to your home state. Most states have reciprocal agreements to prevent double taxation, so you typically claim a credit on one state's return for taxes paid to the other. Check with both states' tax agencies for details on your situation.

Can I deduct federal income taxes from my Maine return?

No, Maine does not allow you to deduct federal income taxes paid. You can deduct state and local property taxes up to $10,000 if you itemize deductions, but federal income tax is not deductible on a Maine return.

What happens if I don't file a Maine return when I should?

Maine charges penalties and interest on unpaid taxes. The penalty for filing late is typically 5% per month of the tax owed, up to 25%. Interest accrues daily on the unpaid balance. If you owe a refund, there is no penalty for filing late, but you will not receive your refund until you file.

Does Maine offer any tax credits I should know about?

Maine offers several credits, including the Earned Income Tax Credit (which mirrors the federal credit), the Property Tax Fairness Credit for homeowners and renters, and credits for dependent care expenses. You claim these on your Maine return. Check the Maine Revenue Services website or your tax software to see which credits explore to your situation.
