Residency rules, sticky taxes, and first-year steps (2026)
2026.1 Edition · Revised 2026-07-24 · DomusDay Research
The move changes the rate; the record decides whether it sticks. California keeps taxing until domicile actually changes — facts and circumstances — closest connections, with no fixed day threshold to hide behind. Below: what follows leavers, and the Texas steps that build the record.
Who has to show it: on the taxpayer to show the FTB's residency determination is wrong; connections are weighed, not counted.
At California's top marginal rate (13.3%), every $100,000 of taxable income is $13,300 of state tax — an illustration at the top bracket, not an effective-rate calculation. Official rate tables are linked below.
Texas voters amended the constitution in 2019: the legislature may not impose a tax on the net incomes of individuals. Reversing it would take another statewide constitutional vote, not just a legislature.
Source ↗Unlike Florida or Nevada, Texas has no statutory declaration-of-domicile instrument. The Texas record is built from dated acts — the license, vehicle and voter registrations, the homestead application, and where life actually happens.
Source ↗After a November 2025 constitutional vote, school districts exempt $140,000 of homestead value. Applications go to the county appraisal district by April 30 — a dated, recorded tie to the new state.
Source ↗Texas is the easy half. California decides whether the move counts, and it decides on evidence — the two tests below stay live until the record closes them out.

The headline delta: California taxes its top bracket at 13.3% while Texas has no personal income tax. At the top marginal rate — an illustration, not an effective-rate calculation — every $100,000 of taxable income is $13,300 of state tax that stops accruing once California residency actually ends. The rules above decide when that is; the day count and the domicile record decide whether it holds up.
The first weeks in Texas matter more than they look: each step below produces a dated document, and dated documents are what answer a California examiner years later. Do them early and the record starts on your side of the timeline.
New residents obtain a Texas driver license within the 90-day grace period; the skills exam is generally waived for a valid out-of-state license.
Source ↗Vehicles are titled in Texas within 30 days of the move.
Source ↗Vehicles are registered within 30 days. Since January 1, 2025, non-commercial vehicles need no safety inspection — a replacement fee is collected at registration instead; emissions testing continues in 17 counties.
Source ↗Voter registration is filed in the county of residence; the registration deadline is the 30th day before an election.
Source ↗The residence homestead exemption removes $140,000 of value from school taxes for an owner occupying the home as their principal residence; applications go to the county appraisal district by April 30, with late filing accepted up to two years.
Source ↗The Texas Constitution exempts the homestead from forced sale for most debts — an automatic feature of Texas homestead status, with exceptions for purchase-money, taxes, and certain liens.
Source ↗Texas registration requires 30/60/25 liability coverage — $30,000 per injured person, $60,000 per accident, $25,000 property damage.
Source ↗Texas has no personal income tax return to file; sole proprietorships are also exempt from the state franchise tax.

Every rule on this page traces to a statute, regulation, or agency publication, listed in full on each state's own plate.
Not for equity already earned. Compensation for California workdays remains California-source when it vests or is exercised after the move, allocated by workday. Only equity earned after the move — from non-California work — escapes.
Form 540NR, the combined nonresident and part-year resident return, with Schedule CA allocating income between the resident and nonresident periods.
No. Article 8 §24-a of the Texas Constitution, approved by voters in 2019, bars the legislature from taxing the net incomes of individuals. There is no personal return to file.
A Texas driver license within 90 days, vehicle title and registration within 30, voter registration in your county, and the homestead exemption application by April 30. Each produces a dated record.
No — Texas has no statutory declaration-of-domicile instrument. The domicile record is built from the license, registrations, the homestead exemption, and the pattern of daily life, so the dated steps above carry the evidentiary weight.
