Moving from Vermont to Colorado: Residency, Taxes, and What to Prove
The top income tax rate drops from 8.75% in Vermont to 4.40% in Colorado. Establishing Colorado residency correctly is what protects that benefit.
Residency Tests Side by Side
Vermont's statutory residency test uses a 183-day threshold. Colorado does not use a simple day-count threshold; it applies a facts-and-circumstances test instead.
| Factor | Vermont | Colorado |
|---|---|---|
| Statutory Residency Test | A person who maintains a permanent home in Vermont and is present in the state for more than 183 days of the taxable year is a Vermont resident for tax purposes, even if domiciled elsewhere. A permanent place of abode does not have to be the person's primary residence; a vacation or ski home maintained year-round still qualifies, which means a Boston or New York domiciliary who keeps a Vermont ski house and crosses 183 days of aggregate Vermont presence becomes a Vermont statutory resident. | Under Colorado Department of Revenue Rule 39-22-103(8)(a), a natural person is a Colorado resident if either domiciled in Colorado or the person satisfies the six-month rule: maintaining a permanent place of abode in Colorado and spending, in the aggregate, more than six months of the tax year in Colorado. A permanent place of abode is any place a person has a possessory right to live, including a leased apartment or an employer-paid apartment the person actually pays for and returns to on days off; a motel room or an RV camp lot without hookups generally does not qualify. |
| Domicile Test | Vermont's domicile regulation (Code Vt. R. 10-060-039-X) defines domicile as 'the place where an individual has a true, fixed permanent home, and to which place, whenever the person is absent, he or she has the intention of returning.' A person can have only one domicile at a time, established by birth, operation of law, or choice, and once established it persists until abandoned through both actual relocation and demonstrated new intent; temporary absences for vacation or business do not change it. The regulation weighs five primary factors: home ownership/rental and usage patterns, time distribution across the year, location of sentimentally significant personal property, business/employment location, and family/school connections. Notably, Vermont's own regulation states that a tax-motivated move is fully valid as long as the intent to relocate is genuine and actions back it up; the taxpayer bears the burden of proving a domicile change by 'clear and convincing evidence,' a higher bar than the simple preponderance standard used in some other states. | Colorado's domicile rule defines domicile as a place of abode combined with the present intention of returning after any absence, regardless of how long the absence lasts. A person can have only one domicile at a time (with a narrow exception for genuine seasonal dual-domicile arrangements), domicile continues until affirmatively changed, and the burden of proving a change rests on the person asserting it. The regulation lists 18 non-exclusive indicia the Department weighs, including prior domicile, length of time in the new place, spouse/dependent location, driver's license and vehicle registration jurisdiction, voter registration, employment location, government benefits received, mailing address for financial documents, professional licenses, prior-year filing positions, and even social media statements of residency; no single factor controls. |
| Day Count Threshold | 183 days | No fixed threshold |
| Any Part of a Day Rule | Not explicitly confirmed in the primary sources reviewed for this dossier; Vermont's own guidance frames the test as a 'combined total of 183 days,' and practitioner summaries describe it as aggregate presence rather than spelling out partial-day counting the way Maine and New York do. Treat any part of a day in Vermont as a full day out of caution until confirmed against the underlying regulation. | The regulation text sets the threshold as 'more than six months' rather than a codified exact day count, so practitioners generally treat it as 183-plus days. The published rule does not spell out an explicit any-part-of-a-day counting convention the way New York's does; absent that guidance, taxpayers close to the line should assume any day with Colorado presence could be counted and keep contemporaneous records. |
| Presumptions | None published | The place where a person currently lives is presumed to be their current domicile, and once domicile is established it is presumed to continue. Spouses are presumed to share a domicile until separated. A person who lives in a motorhome and owns no real property elsewhere is treated as a full-year Colorado domiciliary if their permanent ties are here and they spend more aggregate time in Colorado than anywhere else; conversely, someone who owns a home in another state but travels to Colorado seasonally is not treated as a Colorado domiciliary absent other factors. |

Leaving Vermont
Vermont's 'clear and convincing evidence' burden of proof for a domicile change, a notably higher bar than most states use, is the single biggest exit-audit fact for Vermont: it is not enough to show you were physically elsewhere more; you must affirmatively prove genuine intent through concrete, documented actions. Combined with the ski-home fact pattern (a permanent Vermont vacation property alone can trigger the 183-day statutory test regardless of domicile), Vermont has real teeth against high-income seasonal residents even without the national reputation New York or California carry.
Trailing Income
Vermont has no published convenience-of-the-employer rule; ordinary sourcing rules generally apply to wages, meaning income for work physically performed outside Vermont after a genuine domicile change is not Vermont-source. Vermont does tax Vermont-source income (wages for Vermont work, income from Vermont business activity, gains on Vermont real property) earned by a nonresident after departure.
Part-Year Filing
Part-year and nonresident filers use Form IN-111, Vermont Income Tax Return, generally reporting all income for the resident portion of the year and apportioning Vermont-source income for the nonresident portion, consistent with the standard part-year approach used across most states with a graduated income tax.
Enforcement Methods
Common Exit Mistakes
Establishing Colorado Residency
| Action | Agency | Deadline |
|---|---|---|
| Get a Colorado driver's license | Colorado Division of Motor Vehicles | no fixed statutory day count for the license itself, but establishing residency (90 consecutive days, gainful employment, or operating a business in Colorado) triggers the requirement |
| Register vehicles in Colorado | Colorado DMV / county motor vehicle office | within 90 days of establishing residency under the Colorado Registration Fairness Act |
| Register to vote | Colorado Secretary of State / county clerk | register anytime; Colorado also allows registration in person at a voter service and polling center through Election Day |
Declaration of Domicile
Colorado has no formal declaration-of-domicile filing comparable to Florida's. Domicile is shown entirely through conduct and the 18-factor indicia list in Rule 39-22-103(8)(a): driver's license, vehicle registration, voter registration, spouse/dependent location, employment, professional licenses, mailing address for financial documents, and prior-year filing positions among them.
Homestead
Colorado's homestead exemption (C.R.S. §38-41-201) automatically protects up to $250,000 of equity in an owner-occupied home from most creditors, rising to $350,000 if an owner, spouse, or dependent is 60 or older or disabled; no filing is required. Separately, the Senior Property Tax Exemption (65+, 10 consecutive years of ownership and occupancy) exempts 50% of the first $200,000 of actual value and is a strong domicile-evidence factor precisely because it demands a decade of continuous residence, which the Department or a prior home state can cross-check against a claimed departure date.
Voter Registration
No advance deadline: Colorado permits registration up through and including Election Day at a voter service and polling center, in addition to standard mail and online registration. https://www.sos.state.co.us

New Resident Tax Traps
Colorado taxes a new resident's worldwide income from the date Colorado domicile begins, requiring the DR 0104PN apportionment for the year of the move. Because domicile in Colorado can be established on the very first day of physical presence if intent is clear, a person who moves mid-year with a firm intent to stay does not get a grace period; the six-month rule is a separate, independent trigger that can make someone a resident even without domicile if they keep a permanent Colorado abode.
What Changes on Tax
Vermont Top Rate
8.75%
Colorado Top Rate
4.40%
Moving from Vermont to Colorado drops the top marginal income tax rate from about 8.75% to about 4.4%, a reduction of roughly 4.35 percentage points.
Withholding Reciprocity
Vermont and Colorado do not have a wage-withholding reciprocity agreement with each other, so this move follows ordinary source-state and resident-state filing rules rather than a reciprocity exception.
Community Property Transition
Vermont and Colorado both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
Vermont
Capital gains: Vermont gives taxpayers a choice between two mutually exclusive breaks (not both in the same year): a flat $5,000 exclusion available against any adjusted net capital gain, or a 40% exclusion for qualifying long-term gains (assets held over three years) on eligible business assets. Primary and non-primary residential real estate is excluded from the 40% break. Short-term gains get no preferential treatment and are taxed at ordinary rates up to 8.75%; long-term gains that qualify for the 40% exclusion have an effective top rate closer to 5.25%.
Estate or inheritance tax: Vermont has an estate tax with a $5,000,000 per-person exemption that is fixed and not indexed for inflation, well below the much higher federal exemption. Amounts above the exemption are taxed at a flat 16% rate. Vermont has no separate inheritance tax.
Property tax: Average effective rate runs high for the region, commonly cited around 1.90% statewide, with local rates ranging roughly 1.5% to 2.3% depending on municipal and school funding needs. The annual Homestead Declaration (Form HS-122) is required of every Vermont resident who owns and occupies their home, both to set the correct (homestead vs. nonresidential) education tax rate and to claim any property tax credit.
Sales tax: 6% state rate; over 30 municipalities add a 1% local option tax, producing a combined maximum of 7% where adopted and a statewide average combined rate of roughly 6.24%.
Colorado
Capital gains: Taxed as ordinary income at the flat 4.40% rate. Colorado once allowed a broad $100,000 capital gain subtraction for qualifying property held five-plus years, but for tax years commencing on or after January 1, 2022 that subtraction was narrowed to apply only to capital gains recognized by farmers who file federal Schedule F on the sale of agricultural real property. Nearly everyone else pays the full flat rate on gains.
Estate or inheritance tax: None. Colorado has no estate tax and no inheritance tax.
Property tax: Effective rate is roughly 0.50% of value, among the lowest in the country. Colorado's Senior Property Tax Exemption is a targeted homestead-style break, not a general portability system: it exempts 50% of the first $200,000 of actual value for owners 65 and older who have owned and occupied the home for at least 10 consecutive years, funded by state reimbursement to counties when the legislature appropriates it.
Sales tax: 2.90% state rate, with average combined state-and-local rates around 7.89% once city, county, and special-district taxes are layered on.
Who This Move Applies To
Travel Nurses
In Vermont
Vermont has no nurse-specific tax-home guidance; the general IRS tax-home rules under Publication 463 govern whether stipends stay tax-free, and Vermont's own residency status for a nurse turns on the same domicile and 183-day/permanent-abode tests everyone else faces. A nurse claiming Vermont as a tax home needs to actually maintain and return to a genuine Vermont home, not just a mailing address.
In Colorado
Denver, Colorado Springs, and the Front Range hospital systems make Colorado a significant travel-nurse market. A nurse whose actual domicile is Colorado and who takes Colorado contracts is simply taxed as a resident. A nurse who claims a Colorado tax home while working assignments in other states needs a genuine, regularly used, duplicated-expense Colorado residence; the same indicia list the Department applies to ordinary domicile disputes (driver's license, voter registration, time actually spent) applies to a nurse's claimed tax home, and a thin paper trail risks the same stipend-to-wages reclassification travel nurses face in every state.
Professional Athletes
In Vermont
Vermont has no major professional sports franchises, so it runs no state-specific jock-tax apportionment regime. A Vermont-domiciled athlete owes Vermont tax on worldwide income (with credits for tax paid to other states on away-game duty days) but faces no in-state team creating reciprocal audit interest from opposing states' revenue departments.
In Colorado
Colorado is home to the Broncos, Nuggets, Rockies, and Avalanche, and nonresident athletes on visiting teams owe Colorado tax on the duty days they spend in the state under standard apportionment against total season duty days. Because Colorado's rate is a flat 4.40% with no separate capital-gains carve-out, the jock-tax math is simpler than in graduated-rate states, but the liability is real and applies to every visiting team that plays a game in Denver.
Snowbirds, Long Visitors, and RVers
In Vermont
This is Vermont's signature exposure: a permanent, year-round-maintained vacation or ski home is enough to satisfy the 'permanent place of abode' prong of the statutory-residency test on its own, meaning any owner who crosses 183 aggregate days in Vermont, family ski weekends, remote-work stretches, extended fall visits, can become a Vermont statutory resident regardless of where they consider themselves domiciled.
In Colorado
Colorado's scenario runs in both directions. Wealthy buyers in Aspen, Vail, Telluride, and other mountain resort towns who keep a primary domicile elsewhere need to track aggregate days against the six-month, permanent-place-of-abode threshold, since a leased or owned ski home plainly qualifies as a permanent place of abode. Separately, Colorado's own domiciliaries who spend winters in Arizona or Florida remain presumed Colorado domiciliaries under the regulation's continuing-domicile presumption unless they affirmatively establish a new domicile elsewhere, so simply wintering out of state does not by itself cut Colorado ties.
Remote Workers
In Vermont
Vermont has no published convenience-of-the-employer rule of its own. The friction for a remote worker moving to Vermont usually runs from the origin-state side, particularly for anyone whose employer is based in New York, a convenience-rule state that can still claim to source the wages there even after the worker relocates to Vermont.
In Colorado
Colorado has no convenience-of-employer rule: a nonresident performing all work physically outside Colorado for a Colorado-based employer is not Colorado-taxed on those wages solely because the employer is headquartered here. Colorado has been a significant landing spot for remote workers relocating from California, Texas, and the coasts since 2020, and the state has no reciprocal withholding agreements with any other state, so a genuine mid-year move still requires the DR 0104PN part-year split rather than a simple withholding switch.
Military
In Vermont
Vermont follows the federal SCRA and MSRRA framework: a service member's legal residence does not change solely due to a change in duty station, and an accompanying spouse can generally elect the service member's domicile state under MSRRA for tax purposes.
In Colorado
Colorado follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A service member stationed in Colorado on orders does not become a Colorado domiciliary from the posting alone, and neither does an accompanying spouse who elects to keep the service member's home-state domicile under MSRRA. Colorado also offers a military retirement subtraction that interacts with, but does not simply duplicate, the general pension and annuity subtraction.
Airline Crew
In Vermont
Vermont has no major hub airport for airline crew bases. The federal carve-out under 49 U.S.C. § 40116 (crew wages taxable only by the state of residence or a state where over 50% of pay is earned) still applies to any Vermont-domiciled crew member based elsewhere, but this is not a significant Vermont-specific fact pattern.
In Colorado
Denver International Airport (DEN) is a major hub for United Airlines and a large Southwest Airlines operation, giving Colorado a meaningful resident and crew-base airline population. Federal law (49 U.S.C. §40116) limits state taxation of air carrier employees to their state of residence and any state where they earn more than 50% of their pay, which matters directly for DEN-based crew who fly national routes.
Tools for This Move
Vermont to Colorado FAQ
I own a ski house in Vermont but live in Boston most of the year. Can that make me a Vermont resident?+
Yes, if you maintain the ski house year-round (not just seasonally) and your total Vermont presence exceeds 183 days in a tax year, counting time across multiple trips. A permanent place of abode does not need to be your primary or only home; a year-round-maintained vacation property is enough to satisfy that half of Vermont's statutory-residency test even though your domicile stays in Massachusetts.
Does Colorado use the 183-day rule?+
Not exactly as codified. Colorado's six-month rule under Department Rule 39-22-103(8)(a) makes you a statutory resident if you keep a permanent place of abode in Colorado and spend more than six months (commonly treated as 183-plus days) here in the aggregate during the year, separate from and in addition to the ordinary domicile test.
How hard is it to prove I've actually changed my domicile away from Vermont?+
Harder than in most states. Vermont's domicile regulation requires 'clear and convincing evidence' that you've abandoned your Vermont domicile and established a new one elsewhere, a higher standard than the ordinary preponderance-of-evidence bar many states use. You need both an actual physical relocation and documented, concrete actions demonstrating genuine intent, not just a statement that you moved.
How does Colorado decide if I'm still domiciled here after I move?+
Colorado weighs 18 non-exclusive factors, including where your driver's license, vehicle registration, and voter registration are, where your spouse and dependents live, your employment location, your mailing address for financial documents, and even public statements of residency. No single factor controls, and once Colorado domicile is established it's presumed to continue until you affirmatively establish a new one elsewhere.
I moved to Vermont mostly to lower my taxes. Does that make my domicile claim suspect?+
No. Vermont's own domicile regulation explicitly states that a move made for tax reasons is entirely valid, as long as the underlying intent to relocate is genuine and your actions confirm it. The dispute in practice is almost always about proof, whether you actually did the things a genuine mover does, not about your motive for moving.
I bought a place in Aspen but I'm domiciled in Texas. Do I owe Colorado tax?+
Not from domicile alone, since a person who owns a home in another state but visits Colorado seasonally isn't treated as a Colorado domiciliary absent other factors. But the ski home is a permanent place of abode, so if your aggregate Colorado days exceed six months in a year, the separate statutory six-month rule makes you a Colorado resident regardless of your Texas domicile.
What is the Vermont Homestead Declaration and do I have to file it every year?+
It's an annual filing (Form HS-122), due April 15 with a penalty-risk grace period to October 15, that every Vermont resident who owns and occupies their home must file to get the correct homestead education tax rate and to claim the Property Tax Credit if income-eligible. Because it's filed every single year and tied directly to occupancy, it becomes a running, dated record of your Vermont residency claims that a later audit can check for gaps or contradictions.
What form do I file if I only lived in Colorado part of the year?+
Form DR 0104 along with the DR 0104PN, the Part-Year Resident/Nonresident Tax Calculation Schedule, which prorates your Colorado tax to income earned while you were a Colorado resident plus any Colorado-source income earned before you arrived or after you left.
Does Vermont tax my capital gains the same as regular income?+
Not entirely. You can choose either a flat $5,000 exclusion against any net capital gain, or a 40% exclusion for qualifying long-term gains (held over three years) on eligible business assets, but not both in the same year, and residential real estate does not qualify for the 40% break. Short-term gains get no exclusion and are taxed at Vermont's ordinary rates up to 8.75%.
Does Colorado tax Social Security and retirement income?+
Yes, but with a growing subtraction. Through 2025 the pension and annuity subtraction (which covers qualifying Social Security, pensions, and certain IRA income) is capped at $20,000 for filers 55 to 64 and $24,000 for filers 65 and older. Starting with tax year 2026, Colorado removes that cap entirely, letting any individual subtract their full qualifying pension and annuity income.
Does Vermont tax Social Security in retirement?+
Partially, depending on income. Vermont offers an income-based exemption that reduces or eliminates state tax on Social Security for lower-income households, but middle- and higher-income retirees can still owe Vermont tax on part of their benefits, unlike Maine or New Hampshire, which exempt Social Security entirely regardless of income.
Does Colorado have a capital gains tax?+
Capital gains are taxed as ordinary income at the flat 4.40% rate. Colorado used to allow a broad $100,000 subtraction for long-held qualifying property, but since tax year 2022 that subtraction only applies to farmers who file federal Schedule F on the sale of agricultural real property, so most taxpayers get no special break on gains.
