Moving from Texas to Montana: Residency, Taxes, and What to Prove
Texas's 0% (no individual income tax) top income tax rate becomes 5.65% in Montana. 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 Montana 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.
| Factor | Texas | Montana |
|---|---|---|
| Statutory Residency Test | None. 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 ARM 42.15.109, implementing Mont. Code Ann. §15-30-2101, an individual is a Montana resident for income tax purposes if domiciled in Montana or if the individual maintains a permanent place of abode in Montana. Unlike most states, Montana's rule does not pair the permanent-place-of-abode prong with a codified day-count threshold; residency for the abode prong is instead determined, per the regulation's own language, 'in light of all facts and circumstances.' |
| Domicile Test | For 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. | 'Domiciled' is defined by ARM 42.2.304 as having a residence in Montana as determined under Mont. Code Ann. §1-1-215, the state's general residence statute. That statute treats residence as the place a person returns to in seasons of repose when not called elsewhere for labor or a special or temporary purpose, holds that a person can have only one residence, that a residence cannot be lost until another is gained, and, notably, that if a person claims a Montana residence for any purpose, that location becomes the person's residence for all purposes absent a specific statutory exception. A change of residence requires the union of act and intent, not one alone. |
| Day Count Threshold | No fixed threshold | No fixed threshold |
| Any Part of a Day Rule | Not applicable; Texas has no state-level day-count test. | Montana's regulations do not publish a specific any-part-of-a-day counting convention, because the permanent-place-of-abode prong of the residency test has no attached day-count threshold at all; the Department instead applies a facts-and-circumstances standard to the abode question. |
| Presumptions | None published | None published as a distinct numeric presumption. The general residence statute's 'claim a residence for any purpose, and it's your residence for all purposes' rule functions as Montana's closest analog to a presumption: registering to vote, obtaining a resident hunting or fishing license, or otherwise claiming Montana residency for an unrelated purpose can be used as evidence of Montana domicile for tax purposes. |
| Safe Harbors | None published | None published |
Leaving Texas
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
Common Exit Mistakes
Establishing Montana Residency
| Action | Agency | Deadline |
|---|---|---|
| Get a Montana driver's license | Montana Motor Vehicle Division | within 60 days of establishing residency |
| Title and register vehicles in Montana | Montana Motor Vehicle Division / county treasurer | within 60 days of establishing residency |
| Register to vote | Montana Secretary of State / county election office | regular registration closes 30 days before an election; late registration continues through Election Day (subject to a noon-to-5pm blackout the day before) |
Declaration of Domicile
Montana has no formal declaration-of-domicile filing comparable to Florida's for tax purposes. What Montana does have is a homestead declaration, a separate, unrelated legal mechanism (see Homestead below) that protects home equity from creditors, not a domicile filing, though a recorded homestead declaration is one more piece of paper trail pointing to where a person has claimed Montana as home.
Homestead
Montana's homestead exemption (Mont. Code Ann. §70-32-104) is not automatic: a person must execute, notarize, and record a written declaration of homestead with the county clerk and recorder (§70-32-105) to claim it. It protects home equity from most creditors up to a dollar cap that started at $350,000 in 2021 and adjusts upward roughly 4% a year. Because the declaration is a deliberate, dated, recorded filing rather than something automatic, it functions as unusually strong documentary evidence of when a person claimed a Montana home, useful for establishing residency, but also a loose end that should be released if the property stops being the primary home.
Voter Registration
Regular registration closes 30 days before an election; Montana also allows late registration in person through Election Day itself, though a court fight over Senate Bill 490 has centered on a proposed blackout period the day before Election Day, so voters moving close to an election should confirm current rules with their county election office. https://votemt.gov/voter-registration/
Vehicle Registration Deadline

New Resident Tax Traps
Montana taxes worldwide income from the date Montana domicile begins, requiring Montana Form 2's part-year apportionment for the year of the move. Because Montana's general residence statute treats a claim of Montana residency for any purpose as a claim for all purposes, a new arrival who registers to vote or gets a resident hunting license before formally establishing the rest of their domicile picture may find the state (or their old home state) pointing to that early claim as the actual date domicile began.
What Changes on Tax
Texas Top Rate
0% (no individual income tax)
Montana Top Rate
5.65%
Moving from Texas to Montana raises the top marginal income tax rate from about 0% to about 5.65%, an increase of roughly 5.65 percentage points.
Withholding Reciprocity
Texas and Montana 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 Montana 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 Montana'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.
Montana
Capital gains: Long-term capital gains are carved out of ordinary taxable income and taxed on their own, lower two-bracket schedule: 3.0% and 4.1% for 2026 and 2027, with the bracket break points tracking the ordinary-income bracket structure. Short-term gains are taxed as ordinary income at the regular 4.7%/5.65% rates.
Estate or inheritance tax: None. Montana has no estate tax and no inheritance tax.
Property tax: Effective rate is roughly 0.61% of value. Montana's homestead exemption is not a property-tax break at all but a creditor-protection filing (see Establish); property tax relief instead comes through separate, income-limited programs like the Property Tax Assistance Program and Elderly Homeowner/Renter Credit.
Sales tax: Montana has no general state or local sales tax, one of only five states without one. This is also why out-of-state buyers sometimes register high-value vehicles and RVs through Montana LLCs to avoid their home state's sales tax, a business-registration workaround that has no bearing on personal tax domicile.
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 Montana
Billings, Missoula, and Montana's regional hospital systems generate real but modest travel-nurse demand given the state's population. A nurse genuinely domiciled in Montana who takes Montana contracts is taxed as an ordinary resident. A nurse claiming a Montana tax home while working elsewhere needs a real, regularly used, duplicated-expense Montana residence, since Montana's facts-and-circumstances domicile standard applies the same evidentiary weight to a claimed tax home as it does to any other domicile dispute.
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 Montana
Montana has no major professional franchise in the four big US leagues, so jock-tax exposure runs primarily one direction: Montana-domiciled athletes playing professionally elsewhere are taxed by those other states under their own apportionment rules, while nonresident athletes competing in occasional Montana events (college sports revenue aside) owe Montana tax on Montana-source income under standard nonresident sourcing.
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 Montana
Because Montana's permanent-place-of-abode test has no codified day-count threshold, a long-term visitor or second-home owner in a resort area like Whitefish, Big Sky, or the Flathead Valley cannot rely on staying under a specific number of days the way they could in a state with a 183-day rule; the Department instead weighs the full facts and circumstances of how the home is used and how much time is actually spent there. Montana's own domiciliaries who winter in Arizona or elsewhere remain presumed Montana residents under the 'residence cannot be lost until another is gained' rule unless they affirmatively establish a new domicile.
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 Montana
Montana has no convenience-of-employer rule: a nonresident performing all work physically outside Montana for a Montana-based employer is not Montana-taxed on those wages. Montana, particularly Bozeman, Missoula, and the Flathead Valley around Whitefish and Kalispell, has drawn a wave of remote workers relocating from higher-cost states since 2020, and the lack of a sales tax is a frequently cited draw alongside the income tax simplification.
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 Montana
Montana follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A service member stationed in Montana under orders (Malmstrom Air Force Base near Great Falls is the state's major installation) does not become Montana-domiciled from the posting alone. Montana's 2024 tax simplification added a subtraction for certain resident working military retirees and military survivor-benefit recipients, on top of the general federal SCRA/MSRRA protections.
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 Montana
Montana's airports (Bozeman Yellowstone International being the busiest) are not major airline crew bases, so the more relevant federal carve-out for Montana residents working in transportation is the interstate rail and motor carrier employee rule: federal law limits taxation of such employees with regularly assigned duties in more than one state to their state of residence.
Tools for This Move
Texas to Montana 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 Montana use the 183-day rule?+
No. Montana's residency test is domicile or maintaining a permanent place of abode in the state, but unlike most states, the permanent-place-of-abode prong has no codified day-count number at all. The Department looks at all the facts and circumstances of how the home is used rather than counting to a specific threshold like 183 days.
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.
If I get a Montana hunting license or in-state tuition after I've moved away, does that make me a Montana resident again?+
It can be used against you. Montana's general residence statute says that if you claim Montana residence for any purpose, that becomes your residence for all purposes unless a specific statutory exception applies. Claiming a resident hunting license or resident tuition after claiming to have left is exactly the kind of inconsistent claim the Department, or your new home state, could point to.
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.
Does registering my RV or truck through a Montana LLC make me a Montana resident?+
No. Registering a vehicle through a Montana-formed LLC is a business registration, not a personal residency claim, and by itself has no bearing on your individual tax domicile. It doesn't make you a Montana resident, and it doesn't get you out of your actual home state's residency test either.
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 Montana part of the year?+
Montana Form 2, the Individual Income Tax Return, filed with the part-year/nonresident schedule, which apportions your income between the period you were a Montana resident and the period you were not.
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 Montana tax Social Security?+
Yes, but only to the extent it's included in your federal taxable income, following a 2024 simplification that ended Montana's older, separate and more restrictive Social Security worksheet. Taxpayers 65 and older also get a flat $5,500 subtraction from federal taxable income ($11,000 for a joint return where both spouses are 65+).
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 Montana tax capital gains differently from ordinary income?+
Yes. Long-term capital gains are pulled out of ordinary taxable income and taxed on their own lower two-bracket schedule, 3.0% and 4.1% for tax years 2026 and 2027, well below the 4.7%/5.65% rates on ordinary income. Short-term gains are taxed as ordinary income at the regular rates.
