California taxes residents on worldwide income — up to 13.3%. To stop paying California income tax, you must establish domicile in another state AND sever meaningful ties to California. The California Franchise Tax Board (FTB) aggressively audits high-income departures. Simply buying a home in Nevada isn't enough — the FTB will review your physical presence, business ties, and personal connections. In the year of departure, you file a part-year return.

Introduction
California has the highest state income tax in the US — up to 13.3%. For a high earner, every year in California costs $40,000–$100,000+ more in state tax than living in Texas, Florida, or Nevada. But leaving California is not as simple as buying a home elsewhere — the California Franchise Tax Board (FTB) aggressively audits high-income taxpayers who claim to have departed and continues to assert tax authority over those with remaining California ties.
This guide covers the legal requirements for ending California tax residency, the FTB's audit criteria, the 546-day safe harbor rule, what you owe in the year of departure, and how to properly establish non-resident status.
Section 01
When Do You Stop Being a California Resident?
California uses two tests to determine tax residency:
1. Domicile Test
Domicile is your permanent home — the place you intend to return after absences. California is your domicile if: your family home is in California; you have your primary social and business ties in California; your subjective intent is to remain in California. To end California domicile, you must: (a) move to a new state; (b) establish that new state as your permanent home by all objective measures; (c) not intend to return to California as your primary residence.
2. Safe Harbor Rule (546 Days)
Even after establishing out-of-state domicile, if you spend too much time in California, you may still be treated as a resident. The 546-day rule: you are presumed NOT a California resident if you are outside California for more than 546 days over any consecutive 24-month period (counting from your departure). This is approximately an average of 9+ months outside California per year. Spending fewer than 546 days outside CA can create a presumption of continuing residence that can be rebutted — but requires evidence.
What the FTB Looks For
In audits of claimed non-residents, the FTB examines: credit card records showing California spending; California club memberships; California-registered vehicles and driver's licence; where your medical professionals are; where your spouse and children live; where your business is primarily operated; social media location data; where you voted; California property ownership.
Section 02
Severing California Ties: The Checklist
To successfully establish non-resident status, you need to demonstrate a genuine break from California. The more ties you sever, the stronger your position:
High-Priority Actions
Register to vote in your new state and deregister in California
Get a driver's licence in your new state; surrender California licence
Register your vehicles in the new state
Update your primary address with the US Postal Service, your bank, employer, and all accounts to the new state
Update your will, trust documents, and estate planning to the new state
Establish a primary bank account in the new state
Find primary care physicians and medical professionals in the new state
Business Ties
If you are a business owner: ensure California business activities are transferred or properly structured so they don't create California nexus
Update business registrations to reflect your new primary place of business
Be careful about board memberships, partnerships, or advisory roles in California companies — these can create California-source income for non-residents
What You Can Keep
You can own California property as a non-resident. Rental income from California property remains California-source income and is taxable to non-residents. Capital gains from selling California real estate are also California-source. Keeping a second home in California is permissible but creates a risk factor — the FTB may point to it as evidence of continuing domicile if other ties remain strong.
Section 03
Year of Departure: What You Owe California
In the year you move out of California, you are a part-year resident. File California Form 540NR (Non-Resident or Part-Year Resident). Key rules:
Resident period income: All worldwide income earned while you were a California resident (up to your departure date) is taxed at California rates
Non-resident period income: Only California-source income earned after your departure date is subject to California tax
RSUs and stock options: California has specific rules for equity compensation. The California-taxable portion of RSUs or options is determined by the ratio of days worked in California during the vesting period to total vesting days — even if you exercise after leaving California
Deferred compensation: May be subject to California tax depending on whether it was earned during California residency
Pension distributions: Generally not California-source for non-residents (important exception to note)
Timing Your Move
Strategically, moving early in the calendar year is preferable to moving late — more of your year is spent outside California, reducing the resident-period income. If you plan a major liquidity event (stock sale, business sale), ideally establish non-resident status in a prior tax year before the event occurs. An event after establishing non-residency but before 546 days is a grey area that may require careful documentation.
Section 04
California's FTB Audit Process
California's FTB is known for persistent and detailed audits of high-income taxpayers who claim to have departed. Key facts about the audit process:
Statute of limitations: The FTB can audit for 4 years after a return is filed (3 years plus 1 for substantial omissions)
Residency questionnaire: Departing high-income taxpayers may receive FTB Form 4600 — a detailed questionnaire asking about your location, activities, and ties in the year of departure and following years
Burden of proof: You bear the burden of proving you are NOT a California resident — the FTB does not need to prove you are
Common red flags: Continuing to use California address; frequent California visits; California-based business operations; California children's schools; same employer in California
If you are a high-earner leaving California (particularly if you have stock options, RSUs, a liquidity event, or significant investment income), engaging a California tax attorney or CPA specialised in FTB residency matters before your departure is strongly recommended.
US citizens moving internationally from California face both California FTB residency rules and ongoing US federal tax obligations. Greenback's CPAs handle complex multi-state and international tax situations for Americans on the move.
⚠ Not the cheapest option — best for complex situations and expats who want a dedicated CPA.
Moving states or countries means updating your financial accounts. Wise gives you a multi-currency account you can use from anywhere — hold USD and international currencies, convert at real rates, no monthly fees.

Changing states means updating your payroll and contractor payment setup. Deel handles compliant contractor and employee payments across all 50 US states and 150+ countries.
⚠ For employers and companies only — not for individual freelancers or employees.
Can I live in Nevada but work for a California company?
Yes, as a non-resident remote worker, your income is generally not California-source if you perform your work entirely outside California. If you travel to California for work (meetings, site visits), only the wages for those in-California workdays are subject to California income tax (a 'wage allocation' calculation). If you have a California employer but work remotely from Nevada 100% of the time, you should not owe California income tax on that income — but this needs to be documented carefully and may require coordination with your employer's payroll department to ensure California withholding is stopped.
Q
How long do I need to wait after moving before California stops taxing me?
There is no waiting period as such — you stop being a California resident the day you establish domicile elsewhere with genuine intent to make your new state your permanent home. However, the 546-day rule creates a practical threshold: spending 546+ days outside California in any 24-month period creates a strong presumption of non-residency. The FTB can continue to audit your departure status for 4 years after you file your part-year departure return. Residency determinations are based on facts and intent — not a specific waiting period.
Q
Does California tax your pension if you move out of state?
No — California cannot tax pension income paid to non-California residents. The federal Source Tax Law (4-USC §114) prohibits states from taxing pension income received by non-residents. Once you are no longer a California resident, California has no right to tax your pension distributions, 401(k) withdrawals, or IRA distributions — even if those funds were earned or contributed while you were a California resident. This is a significant advantage for retirees moving from California to a no-income-tax state: their entire retirement income becomes free of California tax once non-resident status is established.
Q
What about California capital gains tax on investments after I move?
After establishing non-residency, gains from selling most investment assets (stocks, funds) are NOT California-source income and are not taxable to California. The exception: (1) Real estate located in California — gains on California real estate are always California-source, taxable to non-residents. (2) RSUs/options with California vesting periods — the California-allocated portion remains taxable. (3) Gains from a California partnership or S-corporation — California-source. For a clean capital gains event (selling non-California stocks, ETFs), established non-residents owe California nothing — a major incentive to establish non-residency before large stock sales.
