Texas Residency Rules 2026: No Income Tax & How to Make It Stick

Who needs to read this

Texas is the biggest no-income-tax state and the most common destination for high earners leaving California and New York. Its ban isn't just statutory: it's written into the state constitution. The details below matter if:

• You're relocating to Texas from an income-tax state and need the departure to survive an audit
• You're a remote worker or founder moving to Austin, Dallas, Houston, or San Antonio
• You're approaching a liquidity event (sale of a company, IPO, large vest) and want Texas residency locked in first
• You split time between Texas and a taxing state, or you're a winter Texan
• You recently arrived and want to know what paperwork actually proves the move

How Texas defines residency

For income tax purposes, Texas has nothing to define. Article 8, Section 24-a of the Texas Constitution states: "The legislature may not impose a tax on the net incomes of individuals, including an individual's share of partnership and unincorporated association income." Voters added that language in November 2019 (Proposition 4, approved with roughly 74% of the vote); undoing it would take another constitutional amendment: a two-thirds vote of both chambers plus a majority of voters.

So there is no Texas residency test, no day threshold, and no individual return. What Texas offers instead is evidence infrastructure for your domicile claim:

• The residence homestead exemption: school districts must exempt $140,000 of your principal residence's value under Tax Code §11.13(b), plus an additional $60,000 for owners age 65+ or disabled under §11.13(c), and any taxing unit may add a local-option exemption of up to 20% of value. To claim it you must own the home, use it as your principal residence, and affirm you claim no other residence homestead in or outside Texas.
• Standard state paperwork: driver's license, voter registration, vehicle registration.

The test that decides whether your move worked is your former state's; Texas has no stake in the fight.

Counting the days

Texas doesn't count days; the state you left does:

• Most taxing states impose statutory residency at 183 days plus an available dwelling, counting any part of a day as a full day.
• In the move year, your day pattern is the core evidence: materially more nights in Texas than in the old state.
• Former-state auditors rebuild your calendar from flights, card activity, and cell-tower data. Keeping your own contemporaneous log (iReside automates exactly this) means you're not arguing against their reconstruction empty-handed.

Domicile: the stickier test

You keep your old domicile until you abandon it and establish a new one, judged by your former state on real-world ties. What makes Texas domicile stick:

• The homestead is your anchor. Buying a principal residence and filing the homestead exemption creates a sworn, dated, third-party record that Texas is your one home, precisely because the application disclaims any other homestead anywhere.
• Move the household: spouse, kids, schools. A family that stayed behind is the argument you lose.
• Swap the paper in the same season: Texas driver's license, voter and vehicle registration, addresses on federal returns, banks, brokers, and insurance.
• Relocate your life's vendors: physicians, dentists, accountants, attorneys, and the memberships and possessions that mark home.
• Shrink the old footprint: sell or genuinely lease out the former residence and cut recurring time there.

Part-year residents and nonresidents

There is no Texas part-year or nonresident return. Move-year filings all point backward:

• A final part-year resident return in the old state, with an explicit residency-end date
• Nonresident returns for trailing source income: rents and gains from real estate there, in-state business and partnership income, and wages for days physically worked there
• Equity compensation earned while working in the old state can remain sourced there at vest or exercise under that state's rules; moving to Texas doesn't rewrite where the work happened
• Interest, dividends, and stock gains generally follow your residence when received: the reason timing a move well before a sale matters, and the reason old states scrutinize that timing

If you bring a business, note the Texas franchise tax applies to taxable entities; it's a business filing, not an individual income tax.

Changing your residency status

The practical sequence:

1. Buy or lease the Texas home and move into it, as a principal residence, not a crash pad
2. File the homestead exemption with your county appraisal district once eligible; it's the single best dated proof of the move
3. Get the Texas driver's license, register vehicles, register to vote, all within the first weeks
4. Dispose of the old home or put it under a genuine long-term lease
5. Spend the balance of the year predominantly in Texas and log it
6. File the old state's final part-year return with a clean break date, and keep two-plus years of records; that's the realistic audit window

How Texas enforces its rules

Against individuals, Texas has nothing to enforce: no income tax, no residency audits, no questionnaires. The Comptroller's attention goes to sales tax and franchise tax; property taxes are assessed and collected locally (and appraisal districts do verify homestead claims, since the exemption requires a principal residence and no competing homestead).

Plan instead for outbound enforcement from your former state:

• Large final-year incomes and pre-sale moves are screened and audited
• Expect subpoenas for card statements, travel records, and cell data, plus cross-checks of licenses, voter rolls, and property records
• A failed departure means back tax at the old state's top rates plus interest and penalties, with no Texas tax paid to credit against it

Common mistakes

• Claiming two homesteads. Keeping an old-state homestead or primary-residence break while filing a Texas homestead application contradicts the sworn statement in it, and hands your old state its best exhibit.
• The paper move. License, mailbox, LLC (with the house, spouse, and workweek still in the old state) is the pattern auditors are trained on.
• Moving weeks before the exit. A residency change that lands just before a liquidity event, with ties intact, gets audited and often loses. Season the move.
• Ignoring total tax cost. High property taxes and sales tax mean the arithmetic depends on your income mix; for big earners it's a clear win, but run the numbers.
• Working regularly back in the old state. Those days remain taxable there as nonresident wages, and heavy presence can re-trigger statutory residency.
• No contemporaneous records. Day counts, closing dates, and utility starts win these audits; memory doesn't.
