Maine treats you as a statutory resident for income tax if you spend more than 183 days in the state during the calendar year and maintain a permanent place of abode there. To stay outside statutory residency, keep your Maine days at 183 or fewer in any single calendar year, or avoid keeping a permanent abode in the state. Note that a separate domicile test can also make you a resident regardless of the day count.

Who it applies to

This matters most if you are:

• A remote worker or frequent traveler spending long stretches in Maine while living elsewhere.
• A second-home owner who keeps a year-round Maine dwelling but claims residency in another state.
• Someone splitting the year between Maine and a lower-tax or no-income-tax state.
• A person moving to or from Maine mid-year whose days may straddle the calendar-year boundary.

The rule applies to individuals regardless of citizenship — it turns on physical presence and available housing in Maine, not on visa status or nationality.

The rule — and why it exists

Maine's income tax law defines residency through two independent routes:

• Statutory residency. More than 183 days of presence in Maine during the calendar year plus a permanent place of abode maintained in the state makes you a resident, even if your true home is elsewhere.
• Domicile. If Maine is your domicile — your true, fixed, permanent home — you are a resident regardless of how many days you spend there.

Why it exists: states use presence and a permanent home as proxies for where your economic life really sits. Pairing the day count with an abode requirement stops people from claiming residency in a low-tax state while effectively living in Maine, and stops a purely day-driven test from catching people who only visit.

Counting the days

1. 1Count each day, or part of a day, you are physically present in Maine during the calendar year (1 January to 31 December).
2. 2Any part of a day generally counts as a full day, unless you are only passing through the state in transit.
3. 3The count resets to zero at the start of each new calendar year — it is a fresh annual tally, not a rolling window.
4. 4You become a statutory resident once you exceed 183 days while also holding a permanent place of abode in the state.

Because the window is the calendar year, a single stay split across a year-end can leave you under the threshold in each individual year even if the trip itself is longer than 183 days.

The permanent abode test

The day count alone is not enough for statutory residency. It also requires that you keep a permanent place of abode in Maine for substantially the whole year — a dwelling suitable for year-round living that you maintain, such as an owned or rented home.

• A place you keep only briefly, or a property not suited to year-round living, generally does not count as a permanent abode.
• A seasonal camp or cottage that is not fit for year-round use often falls outside the definition — though the facts of each property matter.
• A statutory resident is taxed by Maine on worldwide income for the year the test is met, not just on Maine-source income.

Examples

Example 1 — clearly a statutory resident

You own a year-round house in Portland and spend 200 days in Maine over the year while working remotely for an out-of-state employer. You exceed 183 days and keep a permanent abode, so both conditions are met and Maine taxes your worldwide income for that year.

Example 2 — over 183 days but no permanent abode

You spend 190 days in Maine but stay in short-term rentals and hotels, never maintaining a dwelling suitable for year-round living. The day count is exceeded, but without a permanent place of abode the statutory-resident rule does not apply.

Example 3 — a stay split across year-end

You keep a Maine home and stay from 1 October to 30 April — about 210 continuous days. Because the count is per calendar year, roughly 90 days fall in the first year and 120 in the second, so you stay under 183 in each year and avoid statutory residency in both.

Exceptions & edge cases

• Domicile overrides the day count. If Maine is your domicile, you are a resident even with far fewer than 183 days, until you establish a new domicile elsewhere.
• The safe-harbor rules. Maine provides limited safe harbors for domiciliaries who spend most of the year abroad or maintain no permanent abode in Maine and spend very few days there — narrow and fact-specific.
• Part-year residents. Moving into or out of Maine mid-year can make you a part-year resident, taxed as a resident only for the portion of the year you lived in the state.
• Transit and medical days. Time merely passing through, or certain days present only for medical treatment, may be treated differently from ordinary days of presence.

Common misconceptions

• "Under 183 days means I'm safe." False — if Maine is your domicile, you can be a resident with almost no days in the state.
• "The 183 days are all that matters." Statutory residency also needs a permanent place of abode; exceeding the day count alone is not enough without one.
• "Only my Maine income is taxed." A resident — statutory or domiciliary — is taxed on worldwide income for that year.
• "A summer cottage counts as an abode." Not necessarily — a dwelling not suitable for year-round living often falls outside the permanent-abode definition.
