Texas residency for snowbirds: domicile, day counts, and what to track
Texas has no state income tax, making it a top destination for high-earners leaving California, New York, and Illinois. Here's how to establish Texas domicile and survive an old-state audit.
Texas has no state income tax, no estate tax, and a strong homestead protection. It's the destination of choice for tech workers leaving California and finance workers leaving New York. But Texas itself isn't where the audit happens, your old state is, and they have years to come after you.
Why Texas?
Texas's tax profile is straightforward:
- 0% state income tax, same as Florida, Tennessee, Nevada, Wyoming, Washington, South Dakota, Alaska, and New Hampshire (NH taxes interest/dividends only).
- 0% state estate tax, federal estate tax still applies above the federal exemption.
- Strong homestead exemption, Texas's homestead protection is among the most generous in the US.
- Property taxes are higher than other no-income-tax states. Run the math for your situation.
Establishing Texas domicile
Texas, like Florida, doesn't have a residency 'application.' You establish domicile by combining intent and action. The minimum credible package:
- Texas driver's license with your Texas address; surrender your old-state license.
- Texas voter registration at the Texas address (and actually vote).
- Texas vehicle registration and insurance at the Texas address.
- Texas homestead exemption filed on your primary residence.
- Texas bank accounts as your primary banking relationship.
- Texas-based professionals, primary doctor, dentist, accountant.
- Will and trust updated to specify Texas domicile.
- Texas mailing address for all financial accounts.
Texas accepts a 'sworn statement of domicile' for some purposes, but unlike Florida, there's no formal Declaration of Domicile filed with a county clerk. The action checklist above is your evidence.
Day-count strategy by old state
Your audit risk depends on your old state. The numbers to know:
| Old state | Statutory threshold | Aim for |
|---|---|---|
| California | 9-month presumption + facts and circumstances | ≤165 CA days, document every tie severed |
| New York | 184 days + permanent place of abode | ≤165 NY days, no NY apartment if possible |
| New Jersey | 183 days + abode | ≤165 NJ days |
| Illinois | Domicile + abode (no fixed day count) | ≤165 IL days, sever ties |
| Connecticut | 183 days + abode | ≤165 CT days |
| Massachusetts | 183 days + abode | ≤165 MA days |
In all cases, aim for at least 183 days in Texas, more is more defensible. The goal is a clear majority of your time spent in Texas, with the old state in the minority.
Common Texas-relocation pitfalls
- Keeping the California or NY home. States like NY treat year-round availability as a permanent place of abode regardless of domicile.
- Working remotely from old-state offices. 'Just a few days at the SF office' becomes 50+ days a year and a strong tie.
- Spouse and kids stay back. Where your spouse and minor children live is heavily weighted in domicile tests.
- Cell phone billed to old state. Auditors pull cell records first. Update everything.
- No contemporaneous day record. A reconstruction is far less credible than a dated log.
What your old state will do
Expect a residency audit 1–3 years after your first part-year return. The audit will ask for cell tower data, credit card statements, EZ-Pass-equivalent toll records, frequent-flyer history, social media activity, and a full reconstruction of your year. The auditor's reconstruction wins unless yours is better-documented.
California and New York audits target departing residents specifically. Even if you've done everything right, expect a multi-year fight. Your day-count records are the foundation of every defense.
Track it from day one
Tax Days is built for the Texas-relocation playbook. Track Texas days, your old-state days, and any other states you visit. The app projects exact thresholds, fires notifications when you're approaching limits, and exports an audit-ready PDF on demand.
Frequently asked questions
Does Texas have a residency application or declaration like Florida?
No. Unlike Florida's Declaration of Domicile, Texas has no formal declaration filed with a county clerk. You establish Texas domicile through intent and action: a Texas driver's license, voter and vehicle registration, a homestead exemption, Texas banking and professionals, and an updated will naming Texas.
How many days should I spend in Texas after moving?
Aim for at least 183 days in Texas, and generally more is more defensible. The goal is a clear majority of the year in Texas with your old state in the minority, staying comfortably under the old state's statutory threshold.
Will Texas audit my residency?
No, Texas has no state income tax, so there is no Texas return to audit. The audit risk comes from the state you left: expect a residency audit from a state like California or New York roughly 1 to 3 years after your first part-year return.
What are the most common mistakes when moving to Texas?
Keeping the old home (New York can treat a year-round available home as a permanent place of abode), working regularly from old-state offices, leaving a spouse and kids behind, keeping a cell phone billed to the old state, and having no contemporaneous day record are the classic pitfalls.
Is Texas actually cheaper than other no-income-tax states?
It depends on your situation. Texas has no state income tax or state estate tax and a generous homestead protection, but its property taxes are higher than in other no-income-tax states, so it's worth running the math for your own numbers.
