Frequently Asked Questions — Maine State Taxes
Does Maine have a state income tax?
Yes. Maine levies a state individual income tax in 2020. The rates and brackets shown above apply to residents filing as single or married filing jointly. Uses federal standard deduction. Estate tax exemption $6.8M. $300 dependent tax credit.
How do Maine tax brackets work?
Like federal taxes, Maine uses a marginal (progressive) tax system. Only the income within each bracket is taxed at that rate — not all your income. For example, if Maine has a 5% top rate, you pay 5% only on income above the top bracket threshold, not on your entire salary.
What is the difference between marginal and effective tax rate in Maine?
Your marginal tax rate is the rate on your highest dollar of income. Your effective tax rate is your total state tax bill divided by your gross income — always lower than your marginal rate. For example, a worker at the top bracket in Maine may have a marginal rate of 7.1% but an effective rate several points lower due to income in lower brackets.
