Maine's income tax is a progressive system where you pay a higher percentage as your income rises

Maine taxes your income in brackets. That means you do not pay one flat rate on all your earnings. Instead, you pay increasing percentages on different portions of your income. If you earn $50,000, you do not pay the top rate on all of it — you pay the lowest rate on the first portion, a higher rate on the next portion, and so on. Only the income that falls into the highest bracket gets taxed at that bracket's rate.

Maine has four income tax brackets for single filers and four for married couples filing jointly. The brackets change each year because they are adjusted for inflation. The state publishes updated brackets every January on the Maine Revenue Services website.

You will also owe federal income tax on top of Maine's state tax. This guide covers only Maine's state tax rate. Your employer should withhold both from your paycheck, or you may need to pay estimated taxes if you are self-employed.

Key Takeaways

  • Maine uses four tax brackets, and your rate depends on which bracket your total income falls into, not on a single flat percentage.
  • The brackets adjust for inflation each year, so the income thresholds and rates change annually.
  • You can find the current year's brackets on the Maine Revenue Services website under "Tax Rates and Tables."
  • Maine taxes both wages and other income sources, including self-employment income, interest, and capital gains.
  • You will owe federal income tax in addition to Maine state tax, and your employer should withhold both unless you are self-employed.

How the bracket system actually works

Here is a concrete example. Suppose you are single and earn $60,000 in a year when the brackets are (these are example numbers, not current rates): 5.8% on income up to $23,000, 6.75% on income from $23,001 to $55,000, 7.15% on income from $55,001 to $131,000, and 8.75% on income over $131,000.

You would calculate your tax like this: $23,000 at 5.8% equals $1,334. The next $32,000 (from $23,001 to $55,000) at 6.75% equals $2,160. The remaining $5,000 (from $55,001 to $60,000) at 7.15% equals $357.50. Your total Maine income tax would be $3,851.50. Your effective rate — the percentage of your total income that goes to tax — is about 6.4%, even though the top bracket is 8.75%.

This is why the bracket system is called progressive. People with higher incomes pay a larger share of their earnings in tax, but nobody pays the top rate on their entire income.

Where to find the current Maine tax brackets

Maine Revenue Services publishes the current year's tax brackets on its website at maine.gov/revenue. Look for the page titled "Tax Rates and Tables" or search for "Maine income tax brackets." The page lists separate brackets for single filers, married filing jointly, married filing separately, and head of household.

The brackets are updated each January to account for inflation. If you are filing taxes for a previous year, you need the brackets from that year, not the current year. The Maine Revenue Services website archives past years' brackets, or you can call their taxpayer information line at 207-626-8475 during business hours.

If you use tax software or work with a tax preparer, they will use the correct brackets for your filing year automatically. You do not need to look them up yourself unless you are calculating your tax by hand or trying to understand how much you will owe before you file.

What income counts toward Maine's tax

Maine taxes most types of income. This includes wages from a job, self-employment income, interest from savings accounts and bonds, dividends from stocks, rental income, and capital gains (profit from selling investments or property). It also includes income from retirement accounts if you withdraw money before reaching the age specified by the account type.

Some income is exempt. For example, Social Security benefits are not taxed by Maine (though they may be taxed federally). Certain retirement distributions and military pensions may also be exempt or partially exempt, depending on your age and the source. If you receive income from sources other than wages, check the Maine Revenue Services website or speak with a tax preparer to confirm whether it is taxable in Maine.

How withholding and estimated taxes work

If you work as an employee, your employer withholds Maine income tax from your paycheck based on the W-4 form you filled out when you were hired. The W-4 tells your employer how much to withhold. If you claim too many dependents or deductions on your W-4, too little will be withheld and you may owe money when you file. If you claim too few, too much will be withheld and you will receive a refund.

If you are self-employed or have income that is not subject to withholding, you may need to pay estimated taxes. These are quarterly payments you make directly to Maine Revenue Services. You calculate them based on your expected income for the year. If you do not pay estimated taxes and you owe more than $500 when you file, you may face penalties.

You can adjust your withholding at any time by submitting a new W-4 to your employer. If you think you will owe a large amount or receive a large refund, changing your withholding mid-year can help balance it out.

Deductions and credits that reduce what you owe

Maine allows you to reduce your taxable income through deductions. The standard deduction is a fixed amount that depends on your filing status — single, married filing jointly, or head of household. For the 2024 tax year, the Maine standard deduction is $14,600 for single filers and $29,200 for married couples filing jointly. These amounts change each year.

You can also claim itemized deductions if they exceed your standard deduction. Itemized deductions include mortgage interest, property taxes, charitable donations, and medical expenses above a certain threshold. Most people use the standard deduction because it is simpler and often larger.

Maine also offers tax credits, which directly reduce the tax you owe rather than reducing your taxable income. Credits include the Earned Income Tax Credit (EITC) for lower-income workers, the Child and Dependent Care Credit, and the Education Credit. These credits can result in a refund even if you owe no tax.

Filing your Maine income tax return

You file your Maine state tax return on Form 1040-ME, which you submit to Maine Revenue Services. The important date is typically April 15, the same as the federal important date. You can file by mail, electronically through the Maine Revenue Services website, or through tax software that supports Maine returns.

If you cannot file by April 15, you can request an extension. An extension gives you until October 15 to file, but it does not extend the important date to pay any tax you owe. If you owe money, you should pay it by April 15 to avoid penalties and interest, even if you have not filed yet.

You will need your Social Security number, information about your income from W-2s or 1099s, records of any deductions or credits you are claiming, and your federal tax return (since Maine uses some of the same information). If you are unsure whether you need to file, Maine Revenue Services has a filing requirement worksheet on its website.

Frequently Asked Questions

Do I have to pay Maine income tax if I work in Maine but live in another state?

Yes, you owe Maine income tax on income you earn in Maine, even if you live elsewhere. However, you may also owe tax to the state where you live. Some states have reciprocal agreements to avoid double taxation. Contact the tax authority in both states to understand your obligation, or work with a tax preparer who handles multi-state returns.

What happens if I do not file a Maine tax return?

If you owe tax and do not file, Maine Revenue Services will assess penalties and interest on the unpaid amount. The longer you wait, the larger the debt becomes. If you are owed a refund, you have three years to claim it before the state keeps the money. If you have not filed in previous years, contact Maine Revenue Services about filing back returns.

Can I file my Maine return without filing a federal return?

In most cases, no. Maine requires you to file a federal return first and uses information from it on your state return. If you do not have a federal filing requirement, you usually do not have a Maine filing requirement either. Check the Maine Revenue Services website or call 207-626-8475 to confirm your situation.

How do I know if my withholding is correct?

Review your pay stub to see how much Maine tax is being withheld. Compare it to what you expect to owe based on the tax brackets. If you consistently receive a large refund or owe a large amount, your withholding is off. You can adjust it by submitting a new W-4 to your employer at any time.

What if I disagree with my tax bill?

You can file a protest with Maine Revenue Services within 60 days of receiving your bill. Include documentation supporting your position. If you cannot resolve it, you have the right to appeal to the Maine Board of Appeals. Contact Maine Revenue Services for the specific process and forms required.
