Moving from Texas to Colorado: Residency, Taxes, and What to Prove

Texas's 0% (no individual income tax) 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

Neither Texas nor Colorado relies on a simple statutory day-count threshold. Both apply a facts-and-circumstances or closest-connections style test, so day counting alone will not settle a residency question in either direction.

FactorTexasColorado
Statutory Residency TestNone. Texas has no individual income tax, so there is no day-count or statutory-residency test of the kind New York or California runs. 'Residency' matters in Texas for the homestead exemption, in-state tuition, voter eligibility, and driver licensing, each governed by its own separate standard, not a unified tax-residency test.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 TestFor the purposes that do matter, homestead exemption, voter rolls, in-state tuition, domicile is the place you physically occupy as your principal residence with intent to remain, evidenced by your driver's license address, voter registration, and which single property you claim as homestead. Texas Tax Code Sec. 11.13 and Sec. 11.43 are explicit that a person can hold only one homestead exemption at a time, in Texas or any other state.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 ThresholdNo fixed thresholdNo fixed threshold
Any Part of a Day RuleNot applicable; Texas has no state-level day-count test.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.
PresumptionsNone publishedThe 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 Texas

Moderate exit scrutiny (1/5)

Texas does not chase departing residents for income tax because it never taxed their income to begin with. The one real exposure is administrative: keeping a Texas homestead exemption on a property that is no longer your principal residence is a false claim under Tax Code Sec. 11.43(l), and appraisal districts increasingly cross-check homestead rolls against driver's license and voter registration addresses, as well as other states' homestead or principal-residence exemption data, to catch dual claims.

Trailing Income

None at the individual level. Texas does not tax deferred compensation, vested stock option gains, or business income sourced back to a departed resident, because it never taxed any of it while they lived there. The one obligation that follows a person out of Texas is the franchise (margin) tax on a Texas-registered business entity, and that tracks the entity, not the owner's personal residency.

Part-Year Filing

Not applicable; there is no personal income tax return to file part-year in Texas. Departing residents only need to cancel Texas voter registration, let the Texas driver's license lapse or surrender it, and remove the homestead exemption with the county appraisal district once the property stops being their principal residence.

Enforcement Methods

appraisal district cross-checks between homestead exemption address and driver's license/voter registration address
county tax assessor review of homestead rolls for owners who no longer occupy the property
matching against other states' homestead or principal-residence exemption databases to catch dual claims

Common Exit Mistakes

forgetting to remove the Texas homestead exemption after moving, which a county can treat as a penalty-bearing false claim (50% penalty plus interest under Sec. 11.43(l)) once the property is no longer the principal residence
assuming Texas domicile alone shields income from a high-tax former state's exit audit; California, New York, and similar states test whether you genuinely left them, not whether Texas taxes you now
letting a Texas driver's license and voter registration lapse into a new state while still holding the Texas homestead exemption, creating the exact address mismatch appraisal districts are built to flag

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

Texas Top Rate

0% (no individual income tax)

Colorado Top Rate

4.40%

Moving from Texas to Colorado raises the top marginal income tax rate from about 0% to about 4.4%, an increase of roughly 4.4 percentage points.

Withholding Reciprocity

Texas 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

Texas is a community property state and Colorado uses common law marital property rules. Property already characterized as community property generally keeps that character after the move, subject to the destination state's quasi-community-property treatment, while future acquisitions follow Colorado's common law rules.

Beyond Income Tax

Texas

Capital gains: Not taxed. With no individual income tax, capital gains from stocks, real estate, or a business sale, short or long term, are untaxed at the state level.

Estate or inheritance tax: None. Texas repealed its estate tax in 2005 when the tax was tied to the now-defunct federal state death tax credit, and it has never had a separate inheritance tax.

Property tax: No state property tax; rates are set locally by county, city, school district, and special districts, and effective rates are among the highest in the country, commonly in the 1.6-2%+ range, since property tax substitutes for the income tax Texas doesn't collect. The residence homestead exemption ($140,000 off school district taxable value as of the 2025 increase) and a 10% annual cap on appraised-value growth are the main offsets homeowners rely on.

Sales tax: 6.25% state rate, with local jurisdictions allowed to add up to 2% more, for a combined rate as high as 8.25% in most cities.

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 Texas

Because Texas has no income tax, it is one of the most common states travel nurses claim as a tax home, since no Texas return is ever required regardless of how assignment income is sourced. The exposure isn't with Texas, it's federal and multi-state: the IRS still requires a genuine tax home, a Texas residence the nurse pays to maintain and returns to, to justify tax-free stipends under the duplicate-expense logic in IRS Publication 463, and any income-tax state where the nurse actually works still requires a nonresident return on wages earned there regardless of claimed Texas residency.

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 Texas

Texas is home to the Cowboys, Texans, Mavericks, Rockets, Spurs, Rangers, and Astros, and because Texas has no income tax, athletes domiciled here owe no state tax on their home-team salary, only on the 'duty days' spent playing in states that run a jock tax on visiting players. That asymmetry makes Texas domicile a common tax-planning choice among professional athletes generally, not only those on Texas rosters.

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 Texas

Because there is no income-tax day count to trip, long-term visitors and part-year residents face none of the 183-day exposure that drives snowbird planning in New York or California. Texas is instead a destination snowbirds and RVers domicile through, using a homestead or a mail-forwarding domicile service, precisely because spending months elsewhere creates no Texas tax consequence to manage.

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 Texas

No convenience-of-the-employer rule and no income tax mean a genuine Texas remote worker owes Texas nothing on wages, regardless of where the employer is headquartered. The real risk sits with the employer's state: a remote worker may still owe tax elsewhere for days physically worked from an out-of-state office or HQ, a pattern several high-tax states actively audit for among employees who claim to have relocated to Texas.

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 Texas

Texas has no income tax, so service members who claim Texas as home of record owe no state tax on military pay regardless of where they're stationed, making it one of the most popular home-of-record choices in the military. Nonmilitary spouses covered under the Military Spouses Residency Relief Act can elect Texas as their tax domicile alongside the servicemember, which likewise means no state tax on the spouse's income.

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 Texas

DFW and IAH are major hub crew bases for American Airlines and United, and Dallas Love Field is Southwest's headquarters, making Texas domicile attractive for flight crew under the federal Mobile Workforce carve-out for air carrier employees (49 U.S.C. Sec. 40116), which limits state income tax on a crew member's pay to their state of residence plus any state where they earn more than 50% of their compensation. A Texas-domiciled crew member who never crosses that 50% threshold elsewhere owes no state tax on flight pay at all.

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.

Texas to Colorado FAQ

If I move to Texas but still visit family in California all the time, do I still owe California taxes?+

Texas itself will never tax you, it has no income tax. The risk is entirely on the California side: the FTB applies its own closest-connections test regardless of where you've moved, weighing where your spouse and kids live, where you keep a home, and how often you're actually back in California. Frequent, extended California visits, especially for work, medical care, or family obligations, are exactly what the FTB uses to argue you never really left.

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 long do I need to live in Texas before it counts as my real home?+

Texas itself sets no minimum day count, there's no state income tax test to satisfy. What takes time is building the paper trail other states look for: a Texas driver's license (required within 90 days), vehicle registration (30 days), voter registration, and a homestead exemption filed by the following April 30. Your former state's residency test, not a Texas one, is what determines when your move is considered real.

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.

Can I keep my house in my old state after moving to Texas?+

You can, but it complicates your case with the state you left. Keeping a home available 'just in case,' especially unrented or lightly used, is one of the most common self-inflicted audit triggers cited by practitioners, because it signals you never fully abandoned your old domicile. If you keep the property, renting it out on a genuine long-term lease and making Texas your only homestead exemption strengthens the case that Texas is now your one true home.

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.

Does Texas have a Declaration of Domicile like Florida?+

No. Texas has no single filing that establishes domicile. Instead, intent to make Texas your permanent home is shown through the combination of your homestead exemption, driver's license, vehicle registration, and voter registration, all pointing to the same Texas address. Full-time RVers without a fixed home commonly substitute a mail-forwarding domicile service, such as the Escapees program based in Livingston, to satisfy the address requirement.

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.

I'm a full-time RVer with no permanent address. How do I establish Texas domicile?+

You don't need to own property. Texas domicile services (Escapees RV Club's program in Livingston, and similar providers) supply a legal mailing address that Texas DPS and TxDMV accept for a driver's license and vehicle registration. Combine that with voter registration and updated financial and insurance records at the Texas address, and consistency across all four is what auditors in your prior state will look for if they ever question the move.

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.

If I get a Texas homestead exemption, does that prove I'm no longer a resident of my old state?+

It helps, but it isn't dispositive on its own. A homestead exemption is strong, specific evidence of where your principal residence is, and it's legally tied to your ID address, so it's hard to fake. But a former high-tax state will still weigh it against your other ties: where your family lives, where you work, and how much time you actually spend there. Treat the homestead exemption as one piece of a consistent picture, not the whole case.

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.

Considering the reverse move?

Moving the other direction is a different fact pattern, not a mirror image: exit risk and establishment mechanics both flip.
