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.
California uses two tests to determine tax residency:
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.
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.
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.
To successfully establish non-resident status, you need to demonstrate a genuine break from California. The more ties you sever, the stronger your position:
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.
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:
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.
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:
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.

Get Paid Anywhere →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.
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.
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.
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.
