Leaving California: how the FTB decides if you still live there

Updated . Not tax or legal advice.

California does not use a day count to decide residency. The Franchise Tax Board (FTB) asks whether you are in California for other than a temporary or transitory purpose, weighs the strength of your ties to the state, and presumes you are a resident in any year you spend more than nine months there.

The ties the FTB looks at

The FTB says residency depends on the strength of your ties, not only their number, and no single factor decides it. FTB Pub. 1031

AreaWhat the FTB compares
TimeDays in California versus days elsewhere
FamilyWhere your spouse or registered domestic partner and children live
Home and propertyWhere your principal residence is; where you own real property
Official recordsDriver license, vehicle registration, voter registration
Money and servicesBank accounts, where your financial transactions start, medical providers, professional services
Work and communityEmployment, business interests, professional licenses, memberships, social ties

The California Office of Tax Appeals applies the same kind of list, and says the taxpayer bears the burden of showing the FTB's residency determination is wrong. Appeal of Padron

The year you move

File Form 540NR as a part-year resident. California taxes all your income while you are a resident and only California-source income, such as wages for work done in California or rent from California property, after you leave. FTB

Questions people ask

Does California have a 183-day rule?

No. California has no fixed day count. It presumes you are a resident if you spend more than nine months of the tax year in the state, and otherwise weighs your ties. FTB Pub. 1031

Can I keep my California house after I move to Texas or Nevada?

Yes, but where you own real property and where your principal residence is are both factors the FTB weighs. A California home you keep is a tie you will need to outweigh with others. FTB Pub. 1031

Is there a safe harbor for working outside California?

Only for a California domiciliary outside the state under an employment contract for at least 546 consecutive days, with limits: it does not apply if intangible income exceeds $200,000 in a year or the main purpose is to avoid tax. FTB Pub. 1031
