Maine’s state income tax is graduated with three brackets topping out at 7.15%. Your actual tax depends not just on the rate but on the Maine standard deduction and a personal exemption, which lower your taxable income before the brackets apply. This calculator computes Maine state tax for 2024, showing both your marginal rate and your lower effective rate.
How it works
Maine taxes income progressively, so each slice of taxable income is taxed at its own rate:
- Reduce to taxable income. Subtract the Maine standard deduction (about
$14,600single /$29,200joint) and the$5,000personal exemption per filer from your income. - Apply the brackets. For single filers:
5.8%up to$26,050,6.75%from$26,050to$61,600, and7.15%above$61,600. Joint thresholds double; head-of-household sit in between. - Sum the slices. Each bracket only taxes the income that falls within it, so the total is the sum of all slices — that is your Maine income tax.
The effective rate (tax divided by income) is always lower than the top marginal rate because earlier dollars are taxed less.
Tips and example
A single filer with $60,000 of income subtracts the $14,600 standard deduction and $5,000 exemption, leaving $40,400 of taxable income. The first $26,050 is taxed at 5.8% ($1,510.90), and the remaining $14,350 at 6.75% ($968.63), for about $2,479 of Maine tax — an effective rate near 4.1% on gross income, well below the 6.75% marginal rate.
