Vermont Tax Residency Rules: 183-Day Rule & the Ski-House Trap

Who needs to read this

Vermont is a small state with a real income tax (four brackets topping out at 8.75%), a long border with income-tax-free New Hampshire, and one of the country's densest concentrations of out-of-state second-home owners. Its residency rules matter if:

• You own a Vermont ski house or lake camp and spend serious time there
• You live near the Connecticut River and are weighing the Vermont-versus-New Hampshire question
• You're moving to Vermont (remote work, retirement, family) and need to know when residency begins
• You're leaving Vermont for Florida, New Hampshire, or another low-tax state
• You're a remote worker whose employer sits in Boston or New York while you live in Vermont

How Vermont defines residency

Vermont's definition sits in 32 V.S.A. § 5811(11). You are a resident individual for any portion of the taxable year in which either is true:

1. You are domiciled in Vermont: it's your true, fixed, permanent home, the place you intend to return to whenever absent; or
2. You maintain a permanent place of abode in Vermont and are present in the state for more than an aggregate of 183 days of the taxable year.

The second prong is classic statutory residency: it catches people whose legal home is elsewhere but whose actual life happens in Vermont. Both elements must exist: an abode without the days, or days without an abode, doesn't trigger it. A "permanent place of abode" is a dwelling you maintain and can use year-round; a winterized ski house you own qualifies, whether or not you call it a vacation home.

Residents are taxed on income from all sources at rates of 3.35% to 8.75% (2025 rate schedules, the latest published). Nonresidents are taxed only on Vermont-source income.

Counting the days

The statutory test counts presence "in the aggregate" across the whole year: scattered weekends add up.

• The statute requires more than 183 days, so 184 aggregated days of presence with a Vermont abode makes you a resident for that year.
• Vermont hasn't published a generous partial-day carve-out, so the safe planning assumption is that any part of a day in Vermont can count. Ski weekends, foliage weeks, and long summer stretches accumulate faster than second-home owners expect.
• In a residency review, the burden of documenting your whereabouts is effectively yours. Contemporaneous records (an automatic day log like iReside's, plus travel and card records that corroborate it) are what separate a clean answer from a losing argument.

Domicile: the stickier test

Even under 183 days, Vermont can tax you as a resident if it remains your domicile. Vermont's regulation defines domicile in the traditional way (the true, fixed, permanent home you intend to return to), and you keep your Vermont domicile until you establish a new one and abandon the old. The Department weighs the familiar constellation:

• Where your home base actually is: the dwelling you keep, its size and use compared to homes elsewhere
• Family: where your spouse and children live and go to school
• Time: where you spend most of the year
• Work and business ties, professional licenses, and where your income is earned
• Formal declarations: driver's license, voter registration, vehicle registration, addresses on tax returns, and Vermont's annual homestead declaration on a principal residence
• Community ties: doctors, clubs, congregations, and where your valued possessions live

The Department applies this seriously: in a 2022 formal ruling it held that a Vermont resident working in New Hampshire had not abandoned Vermont domicile. A cross-border job, by itself, moves nothing.

Part-year residents and nonresidents

The move year splits at the date domicile (or statutory residency) changes:

• Part-year residents file Form IN-111 with Schedule IN-113, Income Adjustment Calculations, reporting all income for the resident portion and Vermont-source income for the rest
• Nonresidents with Vermont-source income file the same forms, using IN-113 to allocate
• Vermont-source income that follows you out: rent and gains from Vermont real estate, income from a Vermont business or partnership, and wages for days physically worked in Vermont
• Vermont residents get a credit for income tax paid to other states on the same income, but note the New Hampshire asymmetry: no wage tax there means no credit, so Connecticut River commuters pay full Vermont tax

Changing your residency status

To leave Vermont cleanly, work both tests:

1. Establish the new domicile for real: a comparable home in the new state, actually lived in, with family moved
2. Deal with the Vermont house: sell it, or rent it out on terms that genuinely remove your access; an available abode keeps the statutory test alive
3. Get the days right: with any retained Vermont abode, keep aggregate presence at or under 183 days, with margin, and with records
4. Move the paper trail promptly: license, voter and vehicle registration, mailing addresses, and stop filing a Vermont homestead declaration on a home that's no longer your principal residence
5. Shift doctors, advisors, and memberships, and spend holidays where you claim to live
6. File the part-year IN-111/IN-113 with a clear change date, and keep move-year evidence for several years

How Vermont enforces its rules

Vermont's enforcement is moderate but data-assisted, and the state's size cuts both ways: fewer audits than New York, but easy cross-checking.

• The homestead declaration system gives the Department a property-by-property record of claimed principal residences to reconcile against income tax filings
• Filing mismatches draw letters: a homestead declaration without a resident return, a federal return with a Vermont address filed as a nonresident, or Vermont wages with no return at all
• In residency disputes the Department examines the standard evidence set (property records, licenses, voter rolls, employment location, and your day pattern) and formal rulings show it defends domicile claims vigorously
• Trailing obligations are enforced too: Vermont-source rental and business income requires nonresident filings after you leave

Common mistakes

• The ski-house sleepwalk. Maintaining a year-round Vermont home and drifting past 183 aggregate days makes you a full statutory resident (worldwide income, top rate 8.75%) while you still think of yourself as a Bostonian.
• Assuming New Hampshire work fixes Vermont tax. Residents owe Vermont tax on all income; with no New Hampshire wage tax, there's no credit to offset it.
• Counting only long stays. The test is aggregate presence: weekend trips count, and they add up across a year of skiing and summers.
• Keeping the homestead declaration after moving. Declaring a Vermont homestead while claiming Florida residency is a direct contradiction in the state's own records.
• A paper move with the camp intact. New license, new mailbox, same available Vermont home and same seasonal rhythm: that fails both the domicile and statutory tests.
• No day log. More-than-183 "in the aggregate" disputes are won by whoever has contemporaneous records; reconstruct-from-memory calendars rarely survive.
