Maine collects state income tax on wages, self-employment income, and investment gains

Yes, Maine has a state income tax. It applies to residents and part-year residents who earn income within the state. The tax is progressive, meaning the rate increases as your income rises. For the 2024 tax year, Maine's rates range from 5.8% on the lowest bracket to 7.15% on the highest.

Maine taxes wages from employment, self-employment income, interest, dividends, capital gains, and retirement distributions. If you work in Maine but live in another state, you may owe Maine tax on that income depending on your residency status and the other state's reciprocal agreements.

The state also allows certain deductions and credits that can lower your tax bill. These include the standard deduction, dependent exemptions, and credits for property taxes, education expenses, and earned income.

Key Takeaways

  • Maine's income tax rates range from 5.8% to 7.15% depending on your income bracket, and the state taxes most forms of income including wages, self-employment, and investment earnings.
  • You must file a Maine state tax return if you are a resident or part-year resident with income, even if you owe no federal tax.
  • Maine offers a standard deduction that reduces your taxable income, and the amount varies by filing status and age.
  • Part-year residents and people who moved to or from Maine during the year should report only the income earned while they were Maine residents.

Maine's tax brackets and rates for 2024

Maine uses six tax brackets. The lowest rate of 5.8% applies to single filers earning up to $23,200 and married filers filing jointly earning up to $38,700. Each bracket increases in steps, with the top rate of 7.15% applying to single filers earning over $57,550 and married filers earning over $96,250.

These brackets adjust annually for inflation. The Maine Revenue Services website publishes updated brackets each January. If you file jointly, your brackets are wider than if you file single, which means married couples pay tax on a larger portion of income at lower rates.

Maine also taxes capital gains at the same rates as ordinary income. Long-term capital gains (assets held over one year) are not taxed at a preferential rate in Maine, unlike the federal system.

Who must file a Maine state tax return

You must file if you are a Maine resident or part-year resident with income above the filing threshold. The threshold depends on your filing status and age. For 2024, a single person under 65 must file if gross income exceeds $14,200; a married couple filing jointly must file if combined income exceeds $28,400.

Part-year residents must file even if their income falls below the threshold if they had Maine tax withheld from paychecks. You are considered a part-year resident if you moved into Maine or out of Maine during the tax year. Report only the income you earned while you were a Maine resident.

If you are a nonresident who worked in Maine, you may still owe Maine tax on that income. Check whether your home state has a reciprocal agreement with Maine, which can affect whether you file in both states.

Standard deduction and personal exemptions

Maine allows a standard deduction that reduces your taxable income before tax is calculated. For 2024, the standard deduction is $14,200 for single filers, $28,400 for married couples filing jointly, and $21,300 for heads of household. If you are 65 or older, you receive an additional standard deduction of $1,850 for single filers or $1,450 per spouse for married filers.

You can claim an exemption for each dependent, though the exemption amount is modest. Maine also allows you to deduct property taxes paid to Maine municipalities, up to a limit. This deduction is separate from the standard deduction and is claimed on Schedule A if you itemize.

If you itemize deductions instead of taking the standard deduction, you can deduct mortgage interest, charitable contributions, and state and local taxes (subject to federal limits). Most Maine filers use the standard deduction because it is simpler and often results in a lower tax bill.

Tax credits that reduce what you owe

Maine offers several credits that directly reduce your tax liability. The Earned Income Tax Credit mirrors the federal credit and provides money back to low- and moderate-income working people. The amount depends on your filing status, income, and number of dependents.

The Property Tax Fairness Credit helps renters and homeowners with property tax or rent burden. You must meet income limits and file Form 1098-PT to claim it. Maine also offers credits for education expenses, including tuition and student loan interest paid during the year.

Child and dependent care credits are available if you paid for care to enable you to work. The credit covers a percentage of expenses up to a limit. These credits are claimed on your state return and can reduce your tax to zero or result in a refund.

How withholding and estimated tax payments work

If you are employed in Maine, your employer withholds state income tax from each paycheck based on the W-4 form you complete. The withholding is sent to Maine Revenue Services on your behalf. You can adjust your withholding by submitting a new W-4 to your employer if you expect a large refund or owe money at tax time.

If you are self-employed or have income not subject to withholding, you may need to make estimated tax payments to Maine four times per year. Estimated payments are due April 15, June 15, September 15, and January 15. If you underpay, you may owe a penalty and interest.

When you file your return, the total withholding and estimated payments you made are credited against your tax bill. If you overpaid, you receive a refund. If you underpaid, you owe the difference.

Filing your Maine state tax return

You file your Maine return using Form 1040-ME, the Maine Individual Income Tax Return. You must include your federal adjusted gross income and make adjustments specific to Maine. Most filers file electronically through Maine Revenue Services' online system or through tax software that supports Maine returns.

The filing deadline is April 15 unless it falls on a weekend or holiday, in which case it moves to the next business day. 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; you still owe tax by April 15 or you will owe penalties and interest.

You can file by mail by sending your completed return and any required schedules to the Maine Revenue Services address listed in the tax form instructions. Keep a copy for your records and send the original by certified mail if you want proof of delivery.

Frequently Asked Questions

Do I owe Maine income tax if I live in another state but work in Maine?

You may owe Maine tax on income earned in Maine even if you live elsewhere. However, some states have reciprocal agreements with Maine that prevent double taxation. Check with your home state's tax authority and Maine Revenue Services to determine your filing obligation. You may be able to claim a credit on your home state return for taxes paid to Maine.

What happens if I move to Maine partway through the year?

You are a part-year resident and must report only the income you earned after you became a Maine resident. Your standard deduction and tax brackets are prorated based on the number of months you were a Maine resident. File Form 1040-ME and attach a statement explaining your move date and the income earned in each state.

Can I deduct federal income tax paid from my Maine state tax?

No, Maine does not allow a deduction for federal income tax paid. You can deduct state and local taxes (including property tax and sales tax) up to $10,000 on your federal return, but Maine taxes are not deductible on your Maine return.

Is Social Security income taxed in Maine?

Social Security benefits are not taxed by Maine. However, if you receive other income such as wages, pensions, or investment income, you must report those and may owe tax. Retirement distributions from IRAs and 401(k)s are taxable unless they are Roth distributions.

What if I owe Maine income tax and cannot pay by April 15?

Contact Maine Revenue Services to set up a payment plan. You can pay in installments, though you will owe interest and penalties on the unpaid balance. Paying what you can by the deadline reduces the penalty. Maine also offers an online payment system where you can pay by credit card, debit card, or bank transfer.
