Leaving California: How to Establish Nonresident Status

Leaving California for tax purposes takes more than a moving truck and a new driver's license. Whether you are a California resident is a question of fact, and the Franchise Tax Board (FTB) looks at how you actually live as well as what you declare.

Three points drive most outcomes. Substance matters more than paperwork. Evidence matters, because an established domicile is presumed to continue and an FTB residency determination is presumed correct. And some California tax can continue after a genuine move, because California work, real estate, and business activity can still produce California-source income.

This guide covers the residency rules, what the FTB weighs, a practical checklist for the move, and the income California can still tax after you leave. If you are planning a move around a business sale or a large equity event, read it together with our guide to moving out of California before a business sale.

Two routes to California residency

Under Revenue and Taxation Code section 17014, a resident includes anyone in California for other than a temporary or transitory purpose. It also includes anyone domiciled in California who is outside the state for a temporary or transitory purpose. A person who is a resident for only part of the taxable year is a part-year resident under section 17015.5.

These are two separate routes to residency. You do not necessarily have to change domicile to become a nonresident. A California domiciliary who leaves for other than a temporary or transitory purpose can be a nonresident. Conversely, a person domiciled elsewhere can become a California resident by being here for other than a temporary or transitory purpose.

Domicile is your true, fixed, permanent home, the place you intend to return to when you are away. You have only one domicile at a time and keep it until you acquire a new one. Changing domicile requires abandoning the old domicile, actually moving to and living in the new place, and intending to remain there permanently or indefinitely. Your conduct has to support that intention.

Residence turns on the purpose, duration, and circumstances of your presence or absence. A brief visit or a short, defined assignment ordinarily supports temporary status. A long or indefinite job or business undertaking can establish residence, whatever it is called.

For the distinction between these concepts and the connections California weighs, see California Domicile vs. Residency: What Is the Difference?.

The time-based rules in brief

California has no general 183-day bright line. Three time-based rules apply, and none of them settles residency on its own.

Spending more than nine months of the taxable year in California creates a rebuttable presumption of residency under section 17016. There is no reverse presumption that less time establishes nonresidency.
Under the residency regulation, a person domiciled elsewhere who keeps a permanent home there, spends no more than six months in California, and acts here only as a seasonal visitor, tourist, or guest is treated as present temporarily. For a former Californian, this rule requires an actual change of domicile first.
A California domiciliary absent under an employment-related contract for at least 546 consecutive days is treated as a nonresident under section 17014(d). Return visits of up to 45 days a year are disregarded. The safe harbor is unavailable if the individual's intangible income exceeds $200,000 in any taxable year of the contract, tested separately for each spouse, or if the principal purpose of the absence is to avoid tax.

Staying under six months does not by itself establish nonresidency, and failing the safe harbor does not establish residency. For a fuller treatment of the day-count rules, see Beyond the 183-Day Test: How California Decides Residency.

How the FTB weighs your connections

The FTB and the Office of Tax Appeals (OTA) ask where your closest connections are. Appeal of Stephen D. Bragg, 2003-SBE-002 (May 28, 2003), identifies the objective factors. Their weight depends on the circumstances, and the analysis is not a count of boxes checked. The factors fall into five groups.

Time and family, including days in California and elsewhere, where your spouse or registered domestic partner and children live, and where children attend school.
Home, including the location, size, value, ownership, and use of each home, whether a California home remains available, and any homeowner's exemption claims.
Registrations, including your driver's license, vehicle and voter registration, voting history, professional licenses, and the residential address on your filings.
Money and personal life, including where you bank, where your transactions originate, real property and investments, and the location of your doctors, advisers, place of worship, clubs, and social ties.
Work, including where you perform services, where you manage your business, and whether any California assignment is permanent or indefinite.

The law does not require you to sell your California home, buy a larger house elsewhere, or have your spouse move. But an available California home and immediate family remaining here are significant ties, especially when combined with substantial California presence.

Appeal of R. Peters, 2025-OTA-489 (June 27, 2025) (nonprecedential), shows how these factors combine. The taxpayer held a Nevada driver's license and Nevada property and business interests, but kept substantial California residential and family ties. OTA found him a California resident even though his reconstructed California presence was under six months in each year at issue.

Appeal of J. Bracamonte and J. Bracamonte, 2021-OTA-156P (Mar. 22, 2021), is a precedential warning for owners planning a sale. The taxpayers rented a Nevada apartment and obtained Nevada licenses and registrations before selling their business. OTA still concluded that they remained California residents on the sale date, because their formal steps did not match their actual living arrangements.

A practical checklist for the move

These steps support a factual position. They do not create a safe harbor. The record should accurately show where you live, why you moved, and how you use any remaining California connections.

Before the move, put the foundation in place.

Establish a genuine home in the new state that you will actually occupy.
Decide what will happen to the California home. You may sell it, lease it to an unrelated tenant, or keep it and document its use.
Record your reasons for moving in dated correspondence or a contemporaneous memorandum.
Get advice about significant income events before committing to transaction terms.
Start a daily location and workday log.

At the move, change the formal connections.

Move the belongings that matter to you, and relocate your family if they are moving.
Obtain a new driver's license, surrender the California license, and register vehicles as required.
Register to vote in the new state and cancel your California voter registration.
Update residential and mailing addresses accurately with the IRS, employers, banks, brokers, insurers, and entities that issue you K-1s.
End any California homeowner's property tax exemption when you no longer qualify.

After the move, live the move consistently.

Keep records of ordinary spending and activity where you live.
Build community ties and change doctors, dentists, and other professionals where practical.
Move business management, offices, and board activity where appropriate, and review continuing California business obligations separately.
Document the dates and purposes of California visits, including days worked here.
File an accurate move-year Form 540NR when required, and evaluate each later year's filing obligation.
Keep evidence through the applicable assessment periods, and keep basis, carryover, and deferred-gain records longer when needed.

Useful proof includes travel itineraries, credit card and bank statements, phone location history, toll and parking records, utility bills, leases, closing statements, school enrollment, and a calendar of days by state with the purpose of each California trip. The records should agree with one another and with the position on your returns.

Common mistakes that undermine a move

A new address without a change in daily life. A home you rarely occupy can look like a second residence, particularly if your California home stays in regular use.
Substantial California activity without a clear explanation. Extended visits, continuing work here, and family ties are weighed together with your connections elsewhere.
Inconsistent descriptions of your residence. Representing a California address as your current home undermines the position. A legitimate mailing address or the address of retained California property is not inherently inconsistent; describe it accurately.
A sale before the move is established. A closely timed transaction makes the precise residency-change date critical, and last-minute paperwork cannot substitute for the underlying facts.
Unsupported assertions. Missing day logs and receipts make your position harder to prove, and declarations of intent alone may not overcome contrary conduct.

Income California can still tax after you leave

As a nonresident, you are generally taxed only on California-source income. A genuine move therefore calls for a separate review of each significant income item.

Our guide to California nonresident tax covers the broader sourcing categories. For employee and contractor income, see Working in California as a Nonresident.

Wages and bonuses for California work remain California-source even if paid after you leave. Wages for services performed outside California as a nonresident generally are not.
Nonqualified stock options and RSUs are generally allocated by California workdays over the relevant service period. For nonstatutory options, the FTB's Residency and Sourcing Technical Manual measures that period from grant to exercise, or to termination of employment if earlier. For RSUs, it ordinarily runs from grant to vesting.
Incentive stock options generally produce no California-source gain on a qualifying sale after you leave, absent business situs. A disqualifying disposition can produce California-source compensation, and an exercise as a nonresident can create a California alternative minimum tax adjustment tied to California services.
Gain on stock and other intangibles generally follows your residence on the date of sale, subject to business-situs exceptions. An entity's own asset sale requires separate analysis.
California real estate stays California-source. Rental income and sale gain remain taxable wherever you live.
Partnership, LLC, and S corporation income from California sources remains taxable. A partnership-interest sale can include California-source section 751 income under FTB Legal Ruling 2022-02.
Deferred gain from exchanging California property for out-of-state property keeps its California source, and Form FTB 3840 is generally required each year until the gain is recognized.
Qualified retirement income, including pension, 401(k), and IRA distributions, is excluded during nonresident periods under section 17952.5. Federal law, 4 U.S.C. section 114, separately protects certain nonqualified deferred compensation paid in substantially equal installments over life or at least ten years.
Interest and dividends generally follow residence, unless the investment has a California business situs.

Installment sales need a property-specific look. FTB Publication 1100 treats gain on stock sold while you were a resident as California-source even when collected later. Gain on California real estate stays California-source, while gain on out-of-state real estate sold before the move generally does not. Interest received as a nonresident generally follows residence.

Severance and termination payments

A payment labeled “severance” is not automatically sourced by your past California workdays. In Appeal of J. Otting and Y. Otting, 2026-OTA-403P (2026), a precedential opinion, OTA held that severance and medical-premium payments made for releasing employment-related rights were not California-source, because those rights had no California business situs. RSU-related payments in the same package stayed California-source because of their connection to California services. The FTB's January 2026 manual predates Otting and describes severance more broadly. Review the agreement and what each payment actually replaces; neither the label nor a release alone decides the result.

Equity compensation

Time after employment ends does not add non-California workdays to an option or RSU allocation. Appeal of G. Stabile, 2020-OTA-198P (Apr. 28, 2020), approved a grant-to-vesting workday allocation for mirror-share compensation. Appeal of O. Cremel and E. Koeppel, 2021-OTA-222P (May 18, 2021), confirms that equity compensation earned for California services keeps its California source even when a nonresident spouse is taxed on a community-property share. For a closer look at RSU sourcing, see Let's Be Reasonable: Sourcing California's Restricted Stock Unit Income in Tax Notes State.

The year of the move

In the move year, California taxes income from all sources during the resident period and California-source income during the nonresident period. For partnership, S corporation, and trust items, actual realization in each period controls when it can be established. Otherwise, the FTB generally prorates by day under FTB Legal Ruling 2003-1. A distribution date alone does not decide which period income belongs to.

Older discussions sometimes cite an accrual rule in former section 17554. That section was repealed for taxable years beginning on or after January 1, 2002, and should not be applied as current law.

California computes a nonresident's tax rate as if all income were California income, then applies that rate to California taxable income under section 17041. A move can shrink the taxable base without lowering the rate. Capital loss, net operating loss, and passive loss carryovers must also be restated for the nonresident computation.

Founders should note that California does not conform to the federal qualified small business stock exclusion, including its 2025 expansion. Federal QSBS eligibility does not exclude a gain from California tax; residency on the date of sale and the gain's source remain decisive.

Timing a sale or equity event

Establish the residency-change date through real facts before relying on nonresident treatment for a transaction. The tax date of a sale depends on the transaction, including signing, closing, and contract terms. Moving the owner does not eliminate California-source business gain at the entity level, and payment after the move does not erase a California source that already exists.

These issues are covered in depth, including installment sales, earnouts, escrows, and a pre-event review, in Moving Out of California Before a Business Sale: Residency, Timing, and Sourcing.

Residency audits and the burden of proof

A residency audit can involve questionnaires, day counts, financial and travel records, and evidence about both homes. Auditors often reconstruct a calendar of your physical presence and compare it with your returns. An FTB residency determination is presumed correct, but credible evidence can rebut it. If the FTB proposes an assessment, you may protest within the FTB and then appeal to OTA.

The FTB generally has four years after a return is filed to assess under section 19057. That extends to six years for an omission of more than 25 percent of reported gross income under section 19058, and there is no limit when a required return is never filed or a fraudulent return is filed under section 19087. Each year has its own clock. Where residency is genuinely in question, the residency regulation advises filing a return to avoid possible penalties, even if you believe you were a nonresident. For the full picture, see How Far Back Can the IRS and California Audit and Collect?

Planning before you leave

The best time to plan is before you sign a purchase agreement, accept an exit offer, or exercise a large block of equity, while the facts and the transaction terms can still be shaped.

Frequently asked questions

Can I keep my California house after I move?

Yes. It is a significant tie, not an automatic bar to nonresidency. Leasing it to an unrelated tenant reduces its availability to you, while keeping it furnished and using it regularly weighs toward continued residency.

How many days can I spend in California after I move?

There is no generally safe number. The seasonal visitor rule and the employment safe harbor each have specific conditions, and both your California presence and the purpose of each visit matter.

Do I need to file a California return after I move?

Possibly. The move year generally requires a part-year return on Form 540NR, and a nonresident with California-source income above the filing thresholds must file. Where residency is genuinely in question, the residency regulation advises filing even if you believe you were a nonresident.

Can I keep working remotely for my California employer?

Generally, yes. Wages for services performed outside California as a nonresident are not California-source, but wages for days worked here are. Track your workdays. Independent contractors and business owners face different sourcing rules.

Is my severance taxable by California after I move?

It depends on what the payment is for. Compensation for California services stays California-source, but under Otting, payments for releasing employment-related rights can be sourced to your new state of residence. The agreement's terms matter.

Will the FTB rule on my residency in advance?

No. The FTB treats residency as a question of fact and will not issue a written opinion on whether you are a resident for a particular period.

If my spouse stays in California, can I be a nonresident?

Spouses can have different residency status, but a spouse and children here are significant ties. Community-property rules depend on domicile, not simply your spouse's residence, and can leave part of your earnings taxable to a resident spouse.
