Moving From California to Florida: The Financial Guide
California's combination of high state income tax, high housing costs, and aggressive residency auditing makes Florida one of the most-considered relocation alternatives. The financial case is strongest at $200K+ income and weakest at lower-middle incomes.
CA state tax on $200,000 single is roughly $14,500. At $500,000, it is $43,000. At $1,000,000, it is over $100,000 — and California adds the 1% mental-health surtax above $1M of taxable income. Florida applies $0 of state income tax at any income level.
California residency audits are among the most aggressive in the country. The Franchise Tax Board uses cell-phone records, credit-card transaction patterns, and tax filings to challenge claimed non-residency. The 183-day physical-presence test is necessary but not sufficient — the FTB applies a domicile test.
Housing: a $1.4M Bay Area home converts to roughly $750K–$900K of comparable Tampa or Orlando inventory; $600K–$800K of Jacksonville; $1.0M–$1.3M of waterfront-adjacent Sarasota.
Auto insurance: typically lower in Florida vs. CA in non-Miami markets; comparable to higher in Miami-Dade.
Frequently asked questions
Can I keep my California home and still claim Florida residency?+
Possibly, but it complicates the case. The clearest residency claims involve selling the California home or fully converting it to a non-primary use (long-term rental to non-relative). Continuing to use a California home as primary increases audit risk substantially.
Do California-source RSUs get California tax after the move?+
RSUs are generally allocated to the period of service. Service performed in California is California-source even after you move; service performed in Florida is Florida-source. Plan vesting schedules with this in mind.
