- M.G.L. c. 62 § 1(f)
You are a Massachusetts resident for a tax year if you maintain a permanent place of abode in the state and spend more than 183 days of the taxable year there, counting days you are only partly in Massachusetts — even if your domicile is elsewhere. Both conditions must hold. Staying at or under 183 days keeps you below the statutory line, though anyone domiciled in Massachusetts is a resident regardless of days.
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 winterized vacation home can be a permanent place of abode, while a camp or a cottage not prepared for winter generally is not.
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 M.G.L. c. 62 § 1(f), clause (2), applies only when both of these are true for the same taxable 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 continually maintain a dwelling place in Massachusetts, owned or rented — including one owned or leased by your spouse. DOR generally excludes camps, dormitories, barracks, hospital rooms, dwellings with neither kitchen nor bathing facilities or not prepared for winter, and (depending on the facts) hotel or motel rooms.
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 taxable year — January to December for most people. Track your total like this:
- 1Count any day on which you are physically present in Massachusetts for any part of the day.
- 2The statute expressly includes days spent partly in and partly out of Massachusetts, so arrival and departure days both count. Days in the state on active duty in the U.S. armed forces are excluded; Bounded's counter still counts them, so for service members it can warn early.
- 3Add up every such day across the calendar year — the days do not need to be consecutive.
- 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.
- Leased-out homes. A home you lease for at least one year to people unrelated to you or your spouse, with no right to occupy any part of it and without using it as your mailing address during the lease, is generally not your permanent place of abode.
- Temporary stays. A dwelling maintained only during a temporary stay in Massachusetts to accomplish a particular documented purpose — a predetermined period of no more than one year — is generally not a permanent place of abode.
- Charitable giving doesn't decide domicile. The statute bars using qualifying charitable contributions to determine domicile in Massachusetts or anywhere else.
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." The statute counts days spent partly in Massachusetts, 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.
Frequently asked questions
You stay below the statutory-residency day line, yes. But statutory residency is only one route: if Massachusetts is your domicile (your true, fixed home), you are a resident regardless of how few days you spend there.
Yes. The statute itself counts 'days spent partially in and partially out of the commonwealth', so arrival and departure days are Massachusetts days. The one statutory carve-out is days spent in Massachusetts on active duty in the U.S. armed forces, which are not counted.
DOR describes it as a dwelling place you continually maintain, whether or not you own it, including one owned or leased by your spouse. It generally excludes a camp, dormitory, barracks or hospital room, a dwelling with neither kitchen nor bathing facilities or not prepared for winter, and usually a hotel or motel room. A home leased for at least a year to unrelated tenants, with no right for you to occupy it, and a dwelling kept only for a documented temporary stay of up to one year are also excluded.
Yes. You can be a statutory resident of Massachusetts (over 183 days plus a permanent abode) while being domiciled in another state, which can expose the same income to tax in both places until a credit or agreement resolves it.
Statutory residents are taxed on worldwide income. Nonresidents are generally taxed only on Massachusetts-source income, such as wages earned for work performed in the state.
Keep contemporaneous records — travel receipts, calendars, credit-card and phone-location data. Auditors frequently ask you to substantiate where you were on specific days, and the burden is often on the taxpayer.
