Does California Have an Exit Tax? What Still Gets Taxed When You Move Out of California

Last updated: October 30, 2026 · By the Flex Tax and Consulting Group team

Does California have an exit tax? Under current law, no. California does not tax you just for moving out of the state. But leaving doesn’t end your California tax story. California can still tax income tied to the time you lived or worked here, including part of your RSUs and stock options. And the Franchise Tax Board (FTB) can look closely at whether you actually stopped being a resident. If you’re a Bay Area professional, founder or business owner planning a move, this guide covers what still gets taxed, how residency is decided, and what an FTB residency review looks at.

Does California have an exit tax?

No. Under current law, California has no tax that’s triggered just because you move away. It doesn’t tax unrealized gains on your stock or home when you leave. Proposals for wealth or exit-style taxes come up from time to time, but this article covers the rules in effect today.

The reason people call it an “exit tax” is that California keeps taxing income with a California source. And because high earners who move are often reviewed, leaving takes planning and paperwork, not just a moving truck.

When do you actually stop being a California resident?

Under FTB Publication 1031, you’re a California resident if you’re in California for other than a temporary or transitory purpose, or if your home base (domicile) is California and you’re away only temporarily. A few rules shape the answer:

• Closest connections. The FTB looks at where your strongest ties are. No single factor decides it, and the strength of a tie matters more than the number of ties.
• The 9-month presumption. If you spend more than nine months of a tax year in California, you’re presumed to be a resident.
• The 546-day safe harbor. A California domiciliary who works outside the state under an employment-related contract for at least 546 consecutive days can be treated as a nonresident. It doesn’t apply if intangible income (like dividends, interest or stock gains) exceeds $200,000 in any tax year of the contract, or if a principal purpose is avoiding California tax. Return visits of up to 45 days in a tax year are treated as temporary.

The ties the FTB weighs include:

Type of tie	Examples the FTB considers
Registrations	Driver’s license, vehicle registration, voter registration, professional licenses
Personal and family	Where your spouse and children live, your principal home, clubs, place of worship, doctors, accountants and attorneys
Financial	Where your bank accounts are, where your transactions originate, real estate and investments
Work	How permanent your California work assignments are

What California can still tax after you move

As a nonresident, you’re taxed only on California-source income. Here’s how common income types generally line up, based on FTB Publications 1031 and 1004:

Income	California’s general rule for nonresidents
Wages	Taxable where the work is performed. Pay for days worked in California stays California-source.
RSUs	Income at vesting is allocated by California workdays over the vesting period (grant to vest in the FTB’s summary table).
Nonqualified stock options (NSOs)	Income at exercise is allocated by California workdays from grant to exercise.
ISOs	A qualifying sale is capital gain, sourced to where you live when you sell. A disqualifying sale is treated like an NSO for the wage part.
Stock and bond sales	Gain is generally sourced to where you’re a resident at the time of the sale.
California real estate and businesses	Rental income and gains on California property, and income from a California business, stay California-source.
Pensions and IRAs	Pensions and IRA, SEP and Keogh distributions received after you become a nonresident generally aren’t taxed by California.
Installment sales and deferred pay	Depends on when the sale or work happened and what was sold. Review these before you move.

The workday method is the one that surprises Bay Area tech employees most. An RSU grant that vests after you’ve moved can still be partly taxed by California because some of the vesting period was spent working here. We cover the details in California equity compensation when you move to another state and RSU Taxes 101. Partnership interests have their own sourcing rules; see our post on a recent ruling for nonresidents selling a partnership interest.

The year you move: part-year residency and Form 540NR

In the year you leave, you’re a part-year resident. California taxes all income you receive while a resident, and only California-source income after you become a nonresident. Part-year residents and nonresidents with a California filing requirement generally file Form 540NR. The move date you use should match the facts, like when you established your new home and moved your family and belongings.

What an FTB residency review looks at

High earners who leave California are often asked to support their residency position. The FTB’s own guidance gives the time frame:

• It generally has 4 years to audit a return filed before you left.
• There is no statute of limitations on an unfiled return. If California says you owed a return and none was filed, it can come back at any time.
• Keep your address current with the FTB so notices reach you. Unanswered notices can lead to penalties, fees and collection action.

A review usually comes down to records. The questions track the closest-connection factors above: where you lived, where your family lived, where you worked and how many days you spent in each state.

Checklist: before and after you move

1. Get advice before your move date. The timing of a move against RSU vests, option exercises, bonuses and big sales affects what California can tax.
2. Keep a day count. A calendar, travel records and work location logs make the workday allocation and residency support much easier.
3. Move your ties, not just your address. Driver’s license, car and voter registration, doctors, advisors, accounts and memberships all tell the story.
4. Tell your employer and payroll. Update your work location and state withholding so your W-2 matches where you work.
5. File the right California return. Expect a part-year return for the move year, and possibly nonresident returns later for trailing equity income.
6. Keep everything for at least four years. Leases or purchase documents, moving invoices, and records of where you spent your time.

FAQ

Does California have an exit tax?

Not under current law. California doesn’t tax you for moving out, but it can keep taxing California-source income, such as pay for California work and part of your equity compensation.

Will California tax my RSUs after I move?

Possibly. California allocates RSU income by the share of workdays you spent in California during the vesting period, so RSUs that vest after you move can be partly California-taxable.

How does California decide if I’m still a resident?

The FTB looks at your closest connections: where your home, family, work, registrations, accounts and advisors are. Spending more than nine months of the year in California creates a presumption that you’re a resident.

How long can the FTB audit me after I leave California?

Generally 4 years for a return you filed. If a required return was never filed, there is no time limit.

Do I still file a California return the year I move?

Usually yes. Most people file a part-year resident return (Form 540NR) for the year they move, reporting all income while a resident and California-source income afterward.
