Moving to Maine

You are a Maine resident for the year if Maine was your domicile, your permanent home, for the whole year, or if you kept a permanent place of abode in Maine all year and spent more than 183 days here. A resident pays Maine tax on all income, wherever earned, and takes a credit on Schedule A, line 14, for income tax paid to another state on income Maine also taxes. A part-year resident pays Maine tax on everything received while a resident plus Maine-source income from the rest of the year. A nonresident pays only on Maine-source income, and a nonresident employee owes nothing unless they worked in Maine more than 12 days and earned more than $3,000 from Maine sources. All three file the same Form 1040ME; part-year residents and nonresidents add Schedule NR, which computes a credit for the non-Maine share rather than a separate tax. Maine has no reciprocal agreement with any state.

Resident, part-year resident, nonresident

The Department’s instructions define domicile as “the place an individual establishes as their permanent home,” and it continues until a new permanent home is acquired. Moving out of Maine does not end Maine domicile by itself; acquiring a permanent home somewhere else does. The second test is independent of domicile: someone domiciled elsewhere who maintains a permanent place of abode in Maine for the entire year and is in Maine more than 183 days is a Maine resident for that year, whatever their driver’s license says. A summer house kept all year and fit for year-round living can be a permanent place of abode. Days are counted by presence, and part of a day in Maine generally counts as a day in Maine.

Maine-source income includes wages for work performed in Maine, income from a Maine business or rental property, and gain on Maine real estate. Interest, dividends and pension income are sourced to the state of residence when received.

The two safe harbors

Maine lets some people who are still domiciled here be taxed as nonresidents. Under the general safe harbor, a Maine domiciliary who had no permanent place of abode in Maine, maintained a permanent place of abode outside Maine, and spent no more than 30 days of the year in Maine is treated as a nonresident for the year. Under the foreign safe harbor, a Maine domiciliary who spent at least 450 days in a foreign country during any 548-day period is treated as a nonresident for that period, provided the other conditions are met. Both are claimed by checking the safe harbor box on Form 1040ME and filing Schedule NR, and both are audited by counting days, so keep the calendar. The general safe harbor is the one that matters for someone who has moved out of state but not yet cut every tie, for instance a person who sold the Maine house, rents in another state, and keeps a Maine voter registration they meant to change.

The year you move: Schedule NR

Maine does not compute a part-year resident’s tax by taxing only the Maine income. It computes the tax on the whole year’s income as if you were a full-year resident, with the full Maine standard deduction and personal exemption, and then gives a nonresident credit equal to that tax times the share of income that was not Maine’s. Schedule NR, line 7, divides non-Maine adjusted gross income by total Maine AGI; line 9 multiplies the full-year tax by that ratio; the result is the credit, and the balance is the Maine tax. The practical effect is that the non-Maine income still sets your bracket, which costs a little more than a straight proration in a graduated-rate state.

Income is assigned by period. Wages earned while a Maine resident are Maine income; wages earned after the move from a job outside Maine are not. Interest, dividends and capital gains are Maine’s if received while a resident. Pension and IRA payments received while a resident are Maine’s, and the pension income deduction is prorated by the share of pension income received as a nonresident. A bonus paid after the move for work done before it follows the work, and a stock sale follows the residence on the sale date. Worksheets A and B, the residency information and income allocation worksheets, document the split and should be filled before Schedule NR.

Living in Maine, working somewhere else

A Maine resident who earns wages in another state files that state’s nonresident return, pays its tax, and reports the same wages on Form 1040ME, where they are taxed again. The credit for income tax paid to other jurisdictions on Schedule A, line 14, under 36 M.R.S. § 5217-A, relieves the double tax: it equals the tax paid to the other state, limited to the Maine tax on the same income, computed on the Department’s worksheet. If the other state’s rate is higher than Maine’s, the credit is capped and the difference is simply lost; if it is lower, Maine collects the gap. If the other state has no income tax, there is nothing to credit and Maine taxes the wages in full. Starting with 2026, the credit also covers a Maine resident’s share of another state’s pass-through entity tax paid by a partnership or S corporation (verify). The credit is not available for taxes paid to a city or for the other state’s business taxes that are not income taxes.

Without reciprocity, a Maine resident commuting to a job in another state cannot ask the employer to withhold Maine tax instead of the work state’s. The practical answer is to have the work state withhold, estimate the Maine tax net of the credit, and make Maine estimated payments on Form 1040ES-ME if the balance will be $1,000 or more.

Living somewhere else, working in Maine

A nonresident who works in Maine owes Maine tax on wages for days worked in Maine, with a floor: no Maine tax, and no return, unless the person worked in Maine more than 12 days during the year and earned more than $3,000 from all Maine sources. Up to 24 days spent on certain personal services such as training and site inspections do not count toward the 12. The same 12-day, $3,000 test applies to a nonresident doing business in Maine. Someone who crosses the line into Maine for work most of the week is past both thresholds by February and files Form 1040ME with Schedule NR, allocating wages by days worked in Maine on Worksheet C. Their home state, if it has an income tax, generally gives a credit for the Maine tax under its own rules. If the home state has no income tax, the Maine tax is simply the tax on that income; there is nothing to credit it against.

Remote work

Maine sources wages to where the work is physically performed. A Maine resident working from a home office in Maine for an employer based in another state earns Maine-source wages, taxed by Maine, and the other state generally has no claim on them unless it applies a rule of its own that treats a remote employee as working at the employer’s office; whether the other state does so, and whether Maine then gives a credit for it, depends on that state’s law (verify). A nonresident working remotely from home in another state for a Maine employer earns non-Maine wages, and Maine does not tax them; Maine applies no convenience-of-the-employer rule. The employer may still withhold Maine tax out of habit, in which case the fix is a Form W-4ME claiming exemption as a nonresident with no Maine workdays and, if tax was withheld anyway, a Schedule NR return to recover it. Days worked in Maine, even a few, are Maine days, and once they pass 12 with more than $3,000 of pay the Maine return is required.

Military, students, and the pension that follows you

A Maine-domiciled service member keeps Maine domicile wherever stationed, but non-Maine active-duty pay received by a Maine resident is subtracted on Schedule 1S, line 5, and military pay received by a nonresident stationed in Maine is not Maine-source. Military retirement pay is exempt from Maine tax entirely. A spouse covered by the federal Military Spouses Residency Relief Act may keep the service member’s domicile for Maine purposes. A student away at college keeps the parents’ domicile until they establish their own.

Pensions and IRA withdrawals are taxed by the state of residence when received, and federal law bars a former state from taxing the retirement income of someone who has left. A retiree who moves into Maine in May pays Maine on the June-to-December payments, with Social Security subtracted in full and the pension deduction prorated for the nonresident months. A retiree who leaves Maine stops paying Maine on payments received after the move. How the deduction itself works is in Maine for retirees.

The year you move: what to do

• Record the move date and keep evidence of it: closing or lease documents, moving company receipts, the date the new driver’s license and voter registration were issued.
• If you are leaving Maine but keeping a Maine house, understand that keeping it all year plus more than 183 days of Maine presence makes you a Maine resident regardless of where you are domiciled. Keep a day log.
• Ask each employer to stop or start Maine withholding on the move date with a new Form W-4ME, and split the W-2 by period if the employer will not issue two.
• Split interest, dividends, capital gains and 1099-R payments by the date received. Ask the broker for a year-to-date statement as of the move date.
• If you kept a job in the former state after moving to Maine, expect two returns: the former state’s nonresident return and Maine’s, with the Schedule A credit.
• If you moved to Maine from a state with no income tax, start Maine estimated payments in the first quarter after the move if your employer is not withholding.
• Apply for the homestead exemption with your new town by the first April 1 after you have owned the house 12 months; it is not automatic.
• Keep the former state’s final return; Maine may ask for it to verify the Schedule NR allocation.
