Moving from Arkansas to Colorado: Residency, Taxes, and What to Prove
Arkansas's 3.9% top income tax rate becomes 4.40% in Colorado. This move trades a lighter tax environment for a heavier one, so timing income around the transition year matters.
Residency Tests Side by Side
Arkansas'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 | Arkansas | Colorado |
|---|---|---|
| Statutory Residency Test | Arkansas uses a three-pronged test where satisfying any one prong is sufficient to make someone an Arkansas resident for tax purposes: being domiciled in Arkansas, maintaining a permanent place of abode in Arkansas and spending more than 183 days in the state during the year, or other statutory criteria set out in Arkansas Administrative Rule under Ark. Code Ann. Sec. 26-51-102(9). Because any single prong controls, Arkansas's test is structurally broader than states that require both an abode and a day count together. | 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 | Domicile requires an act coupled with intent: physical presence at a place along with the intent to regard that place as a permanent home. A person can maintain several homes at once, but only one can be their domicile, the one they consider and treat as permanent, and it persists until they both leave and establish a new one elsewhere. | 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 | Arkansas's own published guidance frames the abode-plus-time prong around 'more than 183 days'; a detailed any-part-of-a-day rule comparable to New York's was not located in this research pass, so travelers should keep contemporaneous records rather than assume brief visits are automatically excluded. | 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. |
| Safe Harbors | None published | None published |
Leaving Arkansas
Arkansas's residency-audit program has a low public profile relative to the marquee high-tax states. The structural risk for departing residents is Arkansas's three-pronged test itself: because satisfying any single prong is enough to establish residency, a taxpayer who thinks they've left by severing domicile can still be caught if they maintain an Arkansas abode and cross 183 days there in a later year, an easier trigger to hit than in states requiring multiple factors together.
Trailing Income
Arkansas taxes nonresidents on Arkansas-source income, including wages for work physically performed in the state and income from Arkansas real property or business interests, so a departed resident who keeps Arkansas rental property or a pass-through business interest continues filing a nonresident AR1000NR on that income.
Part-Year Filing
Part-year and nonresident filers use Form AR1000NR. A nonresident is defined as someone who lived in Arkansas for less than six months of the year; a part-year resident lived there for part of the year but not the full twelve months and apportions income accordingly.
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
Arkansas Top Rate
3.9%
Colorado Top Rate
4.40%
Moving from Arkansas to Colorado raises the top marginal income tax rate from about 3.9% to about 4.4%, an increase of roughly 0.5 percentage points.
Withholding Reciprocity
Arkansas 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
Arkansas and Colorado both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
Arkansas
Capital gains: Long-term gains (assets held more than one year) are 50% exempt, so only half the gain is taxed at ordinary rates; short-term gains (held one year or less) are fully taxable at ordinary rates.
Estate or inheritance tax: None. Arkansas has no estate tax and no inheritance tax.
Property tax: 0.56% average effective property tax rate. The Homestead Property Tax Credit under Amendment 79 reduces the real property tax bill on an owner-occupied primary residence by $600 for 2026 (raised from $500), with no income restriction, and Amendment 79 also caps annual assessment increases at 5% for homesteads (10% for non-homestead property) and freezes the assessed value for owners 65+ or disabled.
Sales tax: 6.5% state rate, with local option taxes bringing the combined average to roughly 9.48%.
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 Arkansas
Northwest Arkansas's hospital growth and rural facilities statewide create real travel-nurse demand. Arkansas taxes nonresident wages for work physically performed in the state regardless of the nurse's claimed tax home, requiring a nonresident AR1000NR on that income, and because any one prong of Arkansas's three-pronged test is enough to establish residency, a nurse who maintains lodging in Arkansas and crosses 183 days there across contracts risks being pulled into full resident status rather than nonresident treatment.
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 Arkansas
Arkansas has no major professional sports franchise (the Razorbacks are a college program, not a professional team), so it is not a significant duty-day jurisdiction for the traditional pro-athlete jock tax the way Texas, Oklahoma, or Louisiana are with their franchises. College athlete NIL income sourced to Arkansas is a newer area where formal state guidance is still developing.
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 Arkansas
Arkansas's three-pronged test is the sharpest trap for long visitors of the states in this comparison set, because satisfying any single prong establishes residency rather than requiring both an abode and a day count together. A part-year visitor who keeps a place to stay in Arkansas and spends more than six months there in a given year can be treated as a resident even without ever intending Arkansas as a permanent domicile.
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 Arkansas
Arkansas has no convenience-of-the-employer rule; wages are sourced to where work is physically performed. A remote worker living in Arkansas and working for an out-of-state employer owes Arkansas tax on that income as a resident, while someone who moves away but still occasionally performs work from Arkansas can owe nonresident tax on just those days.
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 Arkansas
Arkansas fully exempts military retirement pay from state income tax. Active-duty pay follows the servicemember's SCRA state of legal residence, and a nonresident military spouse present in Arkansas solely due to military orders can generally avoid Arkansas tax on their own wages under the Military Spouses Residency Relief Act if they share the servicemember's non-Arkansas domicile.
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 Arkansas
Arkansas has no major airline hub or flight-crew domicile base; Northwest Arkansas National Airport has grown alongside the Walmart, Tyson, and J.B. Hunt corporate presence in the region, but it functions as a corporate and leisure airport, not a crew base, so the federal Mobile Workforce carve-out for air carrier employees has limited practical relevance for Arkansas residents.
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
Arkansas to Colorado FAQ
I moved out of Arkansas, but I still have a lake house here. Could I still be considered an Arkansas resident?+
Yes, and Arkansas's test makes this easier to trigger than in most states. Because satisfying any one of Arkansas's three residency prongs is enough, domicile, or an abode plus more than 183 days present, keeping a place to stay in Arkansas and spending more than six months there in a year can make you a resident again even if you've genuinely moved your domicile elsewhere.
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.
What tax bracket am I in if I move to Arkansas making $60,000 a year?+
You'd be in Arkansas's top bracket, 3.9% on income above $25,700, with the lower brackets (0% up to $5,099, then 2.0%, 3.0%, and 3.4% on the tiers below that) applying to the income under that threshold. Arkansas's top rate has come down substantially in recent years, from 5.9% in 2022 to 3.9% now.
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.
How is my capital gain from selling stock taxed in Arkansas?+
If you held it more than a year, only 50% of the gain is subject to Arkansas income tax at your ordinary rate; if you held it a year or less, the full gain is taxed at ordinary rates. There's no separate lower capital gains rate, just the 50% exclusion for long-term holdings.
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 form do I file if I only lived in Arkansas part of the year?+
Form AR1000NR, the same form used by both part-year residents and full nonresidents. A part-year resident apportions income between the Arkansas and non-Arkansas periods; a nonresident (someone in Arkansas less than six months) reports only Arkansas-source income.
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 Arkansas tax my military retirement pay?+
No. Arkansas fully exempts military retirement pay from state income tax, in addition to not taxing Social Security benefits.
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.
How much does the Arkansas homestead credit actually save me?+
For 2026, the Amendment 79 Homestead Property Tax Credit is $600 per year, applied directly against the real property tax owed on your primary residence, up from $500 previously. There's no income limit to qualify, and it stacks with the assessment-increase cap and, for owners 65 or older or disabled, an assessed-value freeze.
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.
