Moving from California to Florida: the tax picture
Quick answer: California's top rate is 13.3 percent, and wage earners also pay uncapped state disability insurance, pushing the effective top bite higher. Florida: zero. You file one final part-year CA return for the move year, build your Florida domicile file properly, and the savings start with your first fully Florida year.
Your last California return
Form 540NR handles the part-year split.
The rule that catches movers
Equity compensation earned while you lived in California stays California-source income even if it vests after you move. RSU timing around a move deserves professional math.
The audit reality
The Franchise Tax Board audits big moves hard using a closest-connections test: home, spouse, doctors, gyms, where your dog sleeps. Document everything.
The domicile checklist
Florida driver license and vehicle registration, voter registration, homestead filing if you buy, new doctors and dentists, updated estate documents, and a calendar that proves where you actually slept. Your old state looks at the whole picture, so build it from day one.
The bigger picture
IRS migration data shows California lost about $11.9 billion in adjusted gross income in a single recent year, the largest outflow in the country.
How we handle move years
Part-year and multi-state returns are a specialty here, not an upcharge surprise. One written quote covers the final CA return, the domicile file, and your first Florida-resident year plan.

Do I file a California return for the year I move?
Yes, one last part-year return. Form 540NR handles the part-year split. Income before the move date belongs to California; income after belongs to Florida, which has no income tax return at all.
Will California audit my move?
The Franchise Tax Board audits big moves hard using a closest-connections test: home, spouse, doctors, gyms, where your dog sleeps. Document everything. The defense is boring paperwork done early, and we set it up as part of your move-year return.
What does Florida tax instead?
No state income tax, no state tax on retirement income, and no estate tax. Florida raises revenue through sales and property taxes, so the homestead exemption filing matters.
