Massachusetts can tax you as a resident even if it isn't your home. Under the statutory-residency rule you are a Massachusetts resident for a tax year if you spend more than 183 days in the state during the calendar year and maintain a permanent place of abode there. Both conditions must hold — it is an AND test, not an either/or. Staying at or under 183 days keeps you below the statutory line, though a separate domicile test can still make you a resident.

Who it applies to

This rule matters most if you are:

• A remote worker or frequent traveler who spends long stretches in Massachusetts but calls another state home.
• Someone who keeps a home, condo, or family apartment in Massachusetts while living or working elsewhere.
• A person moving into or out of Massachusetts mid-year, or splitting the year between two states.
• Anyone with a second residence in the state — a vacation home you use regularly can be a permanent place of abode.

It applies to individuals regardless of citizenship or visa status — statutory residency is about physical presence and maintaining a home, not immigration status.

The rule — and why it exists

Statutory residency under MA General Laws Chapter 62, Section 1 applies only when both of these are true in the same calendar year:

• Day count. You are present in Massachusetts for more than 183 days — so day 184 is the day that tips you into statutory residency.
• Permanent place of abode. You maintain a dwelling in Massachusetts suitable for year-round living, owned or rented. A short hotel stay or a place you don't actually maintain generally does not count.

If you have no permanent place of abode in Massachusetts, the day count alone does not make you a statutory resident — no matter how many days you spend there.

Why it exists: states use a combination of substantial physical presence and a maintained home as a proxy for where a person's economic life really sits. The two-pronged test prevents someone from living in the state most of the year while claiming residency somewhere with lower taxes, and it keeps casual visitors without a local home out of the net.

Counting the days

Massachusetts counts presence across the January-to-December calendar year. Track your total like this:

1. 1Count any day on which you are physically present in Massachusetts for any part of the day.
2. 2A partial day generally counts as a full Massachusetts day, so arrival and departure days both count.
3. 3Add up every such day across the calendar year — the days do not need to be consecutive.
4. 4Once the running total exceeds 183 (i.e. reaches 184) and you maintain a permanent abode, the statutory-residency test is met for that year.

Because a partial day counts as a whole day, frequent short trips add up fast. Keep the count concurrent with your abode: the two conditions must overlap in the same year for statutory residency to apply.

Examples

Example 1 — clearly a statutory resident

You are domiciled in Florida but rent a Boston apartment year-round and spend about 200 days in Massachusetts for work. You exceed 183 days and maintain a permanent abode, so you are a statutory resident and Massachusetts taxes your worldwide income for that year.

Example 2 — many days, but no abode

You spend 190 days in Massachusetts on a long project, staying entirely in hotels and short-term rentals you book trip-by-trip. Without a maintained permanent place of abode, the day count alone does not make you a statutory resident — though you may still owe tax as a nonresident on Massachusetts-source income.

Example 3 — a home, but few days

You keep a furnished vacation home on Cape Cod but live mostly abroad, visiting only about 40 days a year. You maintain a permanent abode, but because you are under 183 days, the statutory-residency test is not met — the test requires both conditions.

Exceptions & edge cases

• Domicile is a separate route. If Massachusetts is your domicile — your true, fixed, permanent home — you are a resident even below 183 days and without meeting the statutory test.
• Dual residency. You can be a statutory resident of Massachusetts while domiciled in another state, potentially triggering residency and tax exposure in two states at once.
• Part-year moves. If you genuinely change your domicile into or out of Massachusetts during the year, part-year residency rules can apply rather than full-year statutory residency.
• The abode must be genuinely yours. A property you have fully rented out to tenants and cannot use yourself generally does not count as a permanent place of abode.

Common misconceptions

• "Under 183 days means I'm safe." Only from the statutory test. If Massachusetts is your domicile, you are a resident with any number of days.
• "A day trip doesn't count." A partial day is generally a full Massachusetts day, so even brief visits add to the count.
• "The days have to be in a row." No — statutory residency tallies total days across the calendar year, consecutive or not.
• "Only my Massachusetts income is taxed." As a statutory resident you are taxed on worldwide income; only nonresidents are limited to Massachusetts-source income.
