Moving from Illinois to Texas: Residency, Taxes, and What to Prove
The top income tax rate drops from 4.95% (flat) in Illinois to 0% (no individual income tax) in Texas. Establishing Texas residency correctly is what protects that benefit.
Residency Tests Side by Side
Illinois's statutory residency test uses a 183-day threshold. Texas does not use a simple day-count threshold; it applies a facts-and-circumstances test instead.
| Factor | Illinois | Texas |
|---|---|---|
| Statutory Residency Test | 35 ILCS 5/1501(a)(20) defines a resident as an individual domiciled in Illinois for the taxable year, OR an individual who is not domiciled in Illinois but maintains a permanent place of abode in Illinois and is present in the state for more than an aggregate of 183 days during the taxable year. Spending exactly 183 days keeps a non-domiciliary a nonresident; 184 or more days combined with a permanent Illinois abode makes them a statutory resident taxed on worldwide income. | 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. |
| Domicile Test | Illinois follows the traditional common-law domicile standard under 86 Ill. Adm. Code 100.3020: domicile is the place a person intends as their true, fixed, permanent home, and to which they intend to return whenever absent. A person can have only one domicile at a time, and it continues until a new one is established through both physical presence in the new location and demonstrated intent to abandon Illinois as the permanent home. The Department of Revenue looks at where a person votes, holds a driver's license and registers vehicles, banks, keeps professional relationships (doctor, lawyer, accountant), works, houses family, and belongs to clubs or religious institutions; no single factor controls. | 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. |
| Day Count Threshold | 183 days | No fixed threshold |
| Any Part of a Day Rule | Illinois administrative guidance and practitioner interpretation treat any part of a day physically present in Illinois as a full day for purposes of the 183-day count under 35 ILCS 5/1501(a)(20), consistent with how the Department of Revenue's audit division reconstructs day counts using credit card, toll, and travel records. | Not applicable; Texas has no state-level day-count test. |
| Presumptions | Separate from the statutory 183-day/abode test, 86 Ill. Adm. Code 100.3020 creates an administrative presumption that a person present in Illinois for more than nine months of the taxable year is domiciled in Illinois for that year, while an Illinois domiciliary absent from the state for a full year is presumed to have abandoned Illinois domicile. Both presumptions are rebuttable by facts and circumstances. | None published |

Leaving Illinois
Illinois is not in the top tier of aggressive exit-audit states the way New York or California are, but the Department of Revenue does examine departing high earners, especially where a large capital gain or business sale occurred near the claimed move date, or where the taxpayer kept an Illinois home, spouse, or business presence after claiming nonresidency. Auditors reconstruct day counts using credit card statements, toll records, airline records, and utility usage, and they cross-check the General Homestead Exemption against a claimed out-of-state domicile.
Trailing Income
Illinois does not have a convenience-of-the-employer rule, so a former resident who telecommutes for an Illinois employer from another state generally is not taxed by Illinois on those wages solely because the employer is based in Illinois; sourcing follows where the work is actually performed. Illinois does tax nonresident income that is Illinois-source, including compensation for services actually performed in Illinois, gain on the sale of Illinois real property, and a departing resident's share of Illinois business income allocated under the state's apportionment rules for the period they were still a resident or doing business in the state.
Part-Year Filing
Form IL-1040 together with Schedule NR, Nonresident and Part-Year Resident Computation of Illinois Tax, is used for the year someone moves into or out of Illinois. Schedule NR allocates income between the Illinois-resident portion of the year and the nonresident portion, and computes an Illinois tax based only on Illinois-source and Illinois-period income.
Enforcement Methods
Common Exit Mistakes
Establishing Texas Residency
| Action | Agency | Deadline |
|---|---|---|
| Get a Texas driver's license | Texas Department of Public Safety | within 90 days of establishing residency (an out-of-state license remains valid to drive during that window under Transportation Code Sec. 521.029) |
| Register your vehicle(s) in Texas | County Tax Assessor-Collector / TxDMV | within 30 days of bringing the vehicle into Texas or establishing residency |
| Register to vote | Texas Secretary of State | at least 30 days before the election you want to vote in |
| File for the residence homestead exemption | County Appraisal District | by April 30 of the tax year, with late filing allowed up to two years back in most cases; the address on your driver's license or state ID must match the homestead address |
Declaration of Domicile
Texas has no formal 'Declaration of Domicile' filing the way Florida does. Intent to make Texas a permanent home is built from the combination of the homestead exemption filing, driver's license, voter registration, and vehicle registration rather than a single recorded document. Full-time RVers and others without a fixed address commonly use a Texas mail-forwarding domicile service, the Escapees RV Club's program based in Livingston is the best known, to obtain a qualifying mailing address and satisfy these same requirements without owning property.
Homestead
The residence homestead exemption removes $140,000 of a home's value from school district property taxes (raised from $100,000 by the November 2025 constitutional amendment, Proposition 13, enacted via Senate Bill 4), with an additional exemption for owners 65 or older or disabled, plus a 10% annual cap on appraised-value increases once the exemption is in place. It matters as domicile evidence because a chief appraiser is legally barred from granting it unless the address on the applicant's driver's license or state ID matches the homestead property, precisely the mismatch other states' auditors also look for when someone claims to have left.
Voter Registration
Register through the Texas Secretary of State or your county voter registrar; applications must be received at least 30 days before an election to vote in it. https://www.votetexas.gov/register-to-vote/index.html
Vehicle Registration Deadline
30 days
New Resident Tax Traps
New residents sometimes assume a tax-free state means nothing to plan for, but Texas collects use tax on vehicles and other property bought out of state and brought in (generally the gap between what was paid elsewhere and Texas's 6.25% rate), and local property tax bills can be a real shock relative to a lower-property-tax state of origin, even with the homestead exemption applied.
What Changes on Tax
Illinois Top Rate
4.95% (flat)
Texas Top Rate
0% (no individual income tax)
Moving from Illinois to Texas drops the top marginal income tax rate from about 4.95% to about 0%, a reduction of roughly 4.95 percentage points.
Withholding Reciprocity
Illinois and Texas 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
Illinois uses common law marital property rules and Texas is a community property state. Property acquired during marriage after the move may be characterized differently going forward, which matters for estate planning and for basis step-up on a spouse's death.
Beyond Income Tax
Illinois
Capital gains: No preferential rate. Capital gains are taxed as ordinary income at the same 4.95% flat rate as wages.
Estate or inheritance tax: Illinois has an estate tax with a $4 million exemption per estate that is not indexed for inflation and is not portable between spouses. Rates are graduated from roughly 0.8% up to 16% on the amount above the exemption. There is no separate inheritance tax.
Property tax: Illinois has the highest statewide effective property tax rate in the country, around 1.92% of home value, more than double the national median. The General Homestead Exemption reduces the taxable assessed value of an owner-occupied principal residence by up to $10,000 in Cook County, $8,000 in counties bordering Cook, and $6,000 elsewhere.
Sales tax: State base rate is 6.25%, but local home-rule and county taxes push combined rates as high as 11.5% in parts of Cook, Kane, and Warren counties; the effective statewide average is closer to 8.9%.
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.
Who This Move Applies To
Travel Nurses
In Illinois
Illinois applies its ordinary statutory residency test to a travel nurse the same as anyone else: a nurse not domiciled in Illinois who keeps an Illinois apartment for the duration of an assignment and is present more than 183 days becomes a statutory resident on worldwide income. The more common Illinois exposure is the reverse pattern, where a nurse claims a Florida or Texas tax home but actually lives in and pays Illinois-area rent for most of the year; Illinois-source wages for days actually worked in Illinois are taxable to any nonresident nurse regardless of claimed tax home.
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.
Professional Athletes
In Illinois
Illinois taxes nonresident professional athletes on a duty-day basis: Illinois-source income equals total compensation multiplied by the ratio of duty days in Illinois (games, practices, mandatory team functions) to total duty days for the season; mere travel through Illinois without a game or team event does not create a duty day. This applies to visiting teams playing the Bears, Bulls, Blackhawks, White Sox, and Cubs, and Illinois is regarded by practitioners as an aggressive, well-enforced jock-tax state that historically extended the tax reciprocally to any state that taxed Illinois-based 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.
Snowbirds, Long Visitors, and RVers
In Illinois
The Illinois snowbird risk runs through the nine-month administrative presumption and the 183-day/permanent-abode statutory test together: a retiree who keeps the Illinois house and spends more than roughly nine months there, even while wintering in Florida or Arizona for a few months, risks a presumption of continued Illinois domicile, and anyone who crosses 184 days physically present while keeping any Illinois abode becomes a statutory resident regardless of where they claim domicile. Illinois's General Homestead Exemption is a specific cross-check point if a person claims Florida domicile but keeps the Illinois exemption active.
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.
Remote Workers
In Illinois
Illinois has no convenience-of-the-employer rule. A nonresident who works remotely from another state for an Illinois-based employer is generally not taxed by Illinois on those wages, because Illinois sources employee compensation to where the services are physically performed, not to the employer's location. This makes Illinois meaningfully less sticky for remote workers than New York or a handful of other convenience-rule states.
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.
Military
In Illinois
Illinois follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose home of record is Illinois remains an Illinois domiciliary for tax purposes regardless of duty station unless they take affirmative steps to change domicile, while a servicemember stationed in Illinois on orders, and their qualifying spouse, does not become an Illinois resident solely because of the posting, and military pay is not Illinois-source income for a nonresident servicemember stationed there.
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.
Airline Crew
In Illinois
Federal law (49 U.S.C. §40116) limits states to taxing airline employee compensation only in the employee's state of residence and any state where more than 50% of pay is earned. This protects flight crew based at O'Hare or Midway who are domiciled outside Illinois from having their full compensation pulled into Illinois taxation solely because their duty station is in Illinois.
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.
Tools for This Move
Illinois to Texas FAQ
Does Illinois have a 183-day rule like New York or California?+
Yes, though it works alongside domicile rather than replacing it. Under 35 ILCS 5/1501(a)(20), someone not domiciled in Illinois still becomes a statutory resident taxed on worldwide income if they maintain a permanent place of abode in Illinois and are present more than 183 days in the tax year. Separately, 86 Ill. Adm. Code 100.3020 presumes someone present more than nine months is domiciled in Illinois. Spending exactly 183 days keeps a non-domiciliary a nonresident under the statutory test, but a long-term Illinois abode plus heavy time in the state raises both the day-count and the domicile question at once.
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.
If I move to Florida but keep my Chicago condo, will Illinois still tax me?+
It depends on how much time you spend in Illinois and whether the condo still counts as a permanent place of abode. If you're present in Illinois more than 183 days in a year while the condo remains available to you, you become a statutory resident on worldwide income regardless of your Florida domicile claim. Even below that threshold, keeping the condo, especially if you still claim the General Homestead Exemption on it, is exactly the kind of fact Illinois auditors look for when a taxpayer claims to have left.
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.
Does Illinois have a convenience-of-the-employer rule for remote workers?+
No. Illinois sources employee wages to where the work is physically performed, not to where the employer is headquartered. A nonresident who works remotely from another state for a Chicago-based employer generally is not taxed by Illinois on those wages, which is a meaningful difference from convenience-rule states like New York, and it means remote workers face less Illinois exposure after moving away than they might expect.
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.
How do I file my Illinois taxes for the year I move out of state?+
File Form IL-1040 together with Schedule NR, the Nonresident and Part-Year Resident Computation of Illinois Tax. Schedule NR splits your income between the period you were an Illinois resident, which is taxed in full, and the period after you became a nonresident, when only Illinois-source income is taxed. Skipping Schedule NR and simply filing as a full-year nonresident in your move year is a common and easily flagged mistake.
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.
I work in Illinois but live in Wisconsin. Do I have to file two state returns?+
Illinois has reciprocity with Wisconsin, Iowa, Kentucky, and Michigan, so a Wisconsin resident working in Illinois generally does not owe Illinois tax on those wages and should not have Illinois tax withheld; instead, only Wisconsin taxes that income. If Illinois tax was withheld in error, you file for a refund from Illinois rather than claiming a credit, and you report the income on your Wisconsin return as usual.
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.
Will keeping the homestead exemption on my Illinois house hurt me if I claim Florida residency?+
Yes, it's a direct contradiction auditors specifically look for. The General Homestead Exemption requires the property to be your owner-occupied principal residence as of January 1, so continuing to receive it while filing as an Illinois nonresident and claiming Florida domicile undercuts your own position. If you've genuinely moved, removing the exemption is one of the concrete steps that supports your new domicile claim.
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.
