Commuter taxes 2026

Live in Arizona, work in California

Before you use this estimate

This model assumes a full-year resident of Arizona, ordinary employee wages and all workdays physically in California. Check exemption eligibility before treating a work-state amount of $0 as your own result. Withholding is a prepayment, not final tax liability. Other income, a move during the year, remote work and separate local taxes or credits can change the result.

Which state gives the credit: Not wage reciprocity: reverse-credit arrangement. Eligible Arizona residents report the income on their home-state return, then claim the limited credit for Arizona state income tax on the California nonresident return. Prepare the home-state return first. Do not claim the same credit in both states.

Typical state returns

This is the usual filing pattern, not a determination that you must file. Filing thresholds, age or dependent status, other income and withholding refunds can change which returns you need.

How this $100,000 estimate adds up

These steps follow the selected home, work state, salary and filing status. They reconcile the model's annual liability, not the amounts withheld from your paycheck.

Modeled state income tax for Arizona residence and California work
Step	California work state	Arizona home state
Tax before the modeled other-state credit	$4,911	$2,098
Modeled other-state credit subtracted	$2,098	$0
Tax after that credit	$2,813	$2,098

Total: $2,813 + $2,098 = $4,911 a year. Amounts are rounded for display. Work-state wage exemptions, when applicable, are already reflected in the first row; they are not an other-state credit.

The modeled credit is applied in California, the work state. Do not subtract it again in Arizona. Included county components stay in these amounts; excluded local taxes and credits stay excluded. Federal income tax, payroll programs and refund eligibility are outside this reconciliation.

Single filer, all wages earned in California, 2026 state tax rules, standard deductions. Local income taxes not included.

From paycheck withholding to your returns

Withholding: California payroll may withhold on California-source wages. Reconcile withholding through the California nonresident return; the reverse credit is an annual-return calculation, not an automatic payroll exemption.
Returns: Prepare the Arizona resident Form 140 first, then California Form 540NR and Schedule S. California’s instructions require the other-state return with the credit claim.
Credit or refund: For eligible Arizona residents, California grants the credit for Arizona tax on income taxed by both states. The credit belongs on the California return, not a second credit on the Arizona return, and is limited by Schedule S.

Worked example: $100,000 of wages

Single filer, full-year resident of Arizona, all work performed in California, no other income, standard deductions and modeled personal exemptions. Before credit, California tax is $4,911. Modeled California credit: $2,098. Pay $2,813 to California and $2,098 to Arizona, modeled total $4,911.

Planning estimate: California uses FTB's published 2026 indexed brackets, $5,900 deduction and $158 personal credit from its October 2026 Tax News, checked on 2026-10-13. The model omits exemption-credit phaseouts and special return credits. This amount refresh does not constitute a new review of every filing or credit rule. Arizona’s modeled $16,100 deduction assumes federal-standard-deduction conformity; confirm the filing-year Arizona amount before relying on this estimate.

Annual liability, not paycheck withholding or a refund estimate. Federal tax, payroll programs, other local taxes, special credits and part-year residency are excluded. Local income taxes not included.

Remote-work and local exceptions

California employee wages are generally sourced where services are performed. Arizona remote days need separate allocation; California employer location alone does not make all wages California-source. This example assumes all services were performed in California.

Official forms and instructions

Source audit 2026-10-01. Use the return and instructions for the year you are filing; a current-forms link may still show a prior-year return. Official sources checked; not independently reviewed.

What to do

Keep a record of the days you work in each state, especially if you sometimes work from home.

Special credit rules

CA: Not wage reciprocity: reverse-credit arrangement. Eligible Arizona residents report the income on their home-state return, then claim the limited credit for Arizona state income tax on the California nonresident return. Prepare the home-state return first. Do not claim the same credit in both states.

Frequently asked questions

Do I pay California income tax if I live in Arizona?

California taxes eligible wages earned there before credit. In this $100,000 example its tax before credit is about $4,911, and its modeled tax after the eligible credit for Arizona state tax is $2,813. Prepare the Arizona return first; credit limits, other income and local taxes need a separate check.

Do I have to file taxes in both Arizona and California?

Prepare the Arizona resident Form 140 first, then California Form 540NR and Schedule S. California’s instructions require the other-state return with the credit claim.

Will I be taxed twice?

The modeled state credit reduces overlap on eligible wages; separate local taxes or sourcing differences can still leave additional tax. California credits the tax you pay Arizona, so your total is about $4,911 on $100,000, compared with $2,098 if you also worked in Arizona. Local city or county taxes may still apply.
