I moved from California to Texas mid-year — how do I file in both states?
You file a part-year resident return in each state: Form 540NR in California for the months you lived there, and a part-year return in the state you moved from — Texas has no individual income tax, so there is no Texas return to file, but the California part-year return covers only income earned during your California residency period. Splitting income by the exact move date, not evenly across the year, is the step people most often get wrong.
What "part-year resident" means
When you change your state of residence mid-year, most states tax you only on the income you earned while you lived there. California's Form 540NR is the return for nonresidents and part-year residents. On it, you report your total federal income, then allocate only the portion attributable to your California residency period using Schedule CA (540NR).
| Item | How it's handled |
|---|---|
| Wages | Allocate by pay dates: earnings from work performed / paychecks dated while you were a California resident go to California; earnings after the move go to the new state |
| Bonus paid after the move | Sourced separately — check which period it was earned in, not just the pay date |
| Interest, dividends, capital gains | Generally follow your state of residence at the time the income was received or the sale occurred |
| Rental income | Taxed by the state where the property sits, regardless of where you live |
| W-2 withholding | Your employer should switch withholding on the first payroll after the move — tell payroll the week you move |
The move-month payroll trap
Your W-2 shows wages in Boxes 15–18 by state, but employers don't always split them cleanly at the move date. Compare your W-2 state wages against your actual pay stubs: only income earned during the California residency period belongs on the California return. If the employer kept withholding California tax after you moved, the excess comes back as a refund on your California return — it is not lost, but you have to claim it.
What to do before and after the move
- Document the move date — keep the lease or closing statement from the new state, plus the California lease-end record. Either state can ask which day residency changed.
- Update withholding immediately — file a new W-4 and the new state's equivalent with your employer; withholding follows residency from the date it changes and takes effect from the next payroll run.
- File California Form 540NR, allocating income by the residency split, with exact move-in/move-out dates entered in the personal information section.
- No Texas return — Texas has no individual income tax, so nothing is owed or filed there. (If you moved to a state that does have an income tax, you would file a part-year return there too, covering income from the move date onward.)
Frequently asked questions
What if I moved but my employer kept withholding California tax all year?
That is common. The withheld amount beyond what you actually owe California for the residency period is refundable — file the 540NR showing the correct California-source income and the state refunds the difference. Separately, fix the withholding going forward so the money isn't tied up until tax season.
Do I owe California tax on income earned in Texas after I moved?
No. As a part-year resident, California taxes only income from your California residency period (plus any California-source income, like rent from a California property, regardless of residency). Post-move Texas wages are not California income.
What counts as proof of my move date?
A new lease or home purchase closing, a Texas driver's license issue date, voter registration, utility start dates, and the employer's payroll-change record. Keep at least two or three independent documents — they matter most if either state questions the split.
