I moved to Florida years ago — why is California still coming after me for taxes?
Because California taxes based on domicile and "closest connections," not just where you say you live now. If the Franchise Tax Board (FTB) decides you never truly severed your California ties, it can treat you as a California resident for the years in question and bill you for tax on your worldwide income, plus interest and penalties. You beat this by proving — with documents — that you moved permanently and cut the ties that count.
Why California is the hardest state to leave
Most states accept that you moved once your address changes. California doesn't. Its rule: you remain a California resident until you prove otherwise. The burden of proof is on you, not the FTB.
California courts use the "closest connections" test from Appeal of Bragg (2003), which lists nineteen objective factors. FTB auditors group them into three buckets:
| Category | What auditors check |
|---|---|
| Registrations and filings | Driver's license, vehicle registration, voter registration and voting history, homeowner's property tax exemption, address on tax returns |
| Personal and professional ties | Where you work, where your children go to school, bank accounts, memberships (social, religious, professional), your doctors, dentists, accountants, attorneys, business interests, professional licenses |
| Physical presence and property | Location and value of homes, where your spouse and children live, travel patterns, credit-card and phone location data |
Owning a home in California while not filing a California return is the single most common audit trigger — the FTB cross-references property tax records against filed returns.
The residency audit process
A California residency audit usually starts with an inquiry letter asking about your connections. The auditor then works through the Bragg factors, requesting bank statements, travel records, calendars, and third-party declarations. The FTB has reviewed credit-card spending to show a taxpayer was physically in California far more than claimed. If it reclassifies you as a resident, you owe tax on your full worldwide income for those years, plus interest (which accrues from the original due date) and penalties.
Note the timing rules: spending more than 9 months in California in a year creates a presumption that you are a resident. Leaving for employment outside the state generally takes 18 months before you are presumed a nonresident. These are rebuttable presumptions — but they set the starting position.
A practical checklist for cutting domicile cleanly
Do all of these in the first months after leaving California, and keep dated proof of each:
- Get a Florida (or new-state) driver's license and register your vehicles there; surrender or let the California license lapse
- Register to vote in the new state and vote there
- Sell the California home, or at minimum stop claiming the California homeowner's property tax exemption on it
- Move bank accounts, brokerage accounts, and financial-advisor relationships to the new state
- Find a new primary-care doctor, dentist, and other professionals in the new state
- Move memberships (gym, clubs, religious organizations) and professional licenses
- Update your address on all tax returns, insurance, and federal records
- Keep a travel log if you still visit California — the FTB counts days
- Document the intent to stay permanently: a home purchase, a spouse and children's move, enrollment of children in new schools
Frequently asked questions
I left years ago and never got audited. Am I safe?
Not necessarily. The FTB can open prior years if it believes you filed incorrectly. Keeping the move documentation indefinitely is the cheap insurance — the records are what wins a residency case.
I still own a rental property in California. Does that keep me a resident?
Investment property alone does not make you a resident, but it is a connection the FTB will examine, and the rental income is California-source income you must report on a nonresident return (Form 540NR) regardless. Sell it or manage it cleanly — and keep filing the 540NR for it.
Is there a form to declare I am no longer a California resident?
No. California has no official exit form or declaration process. Your actions and documentation are the entire case.
