California vs Florida Income Tax: The Savings by Income Tier

The income tax savings are the reason most California buyers look at Florida. The real estate is what keeps them here once they arrive.

Income Tax Savings by Income Tier and Income Type

(1) Earned income (salary, W-2): California taxes earned income progressively. The 13.3% top marginal rate applies to income above $1M. The blended effective rate on $500K: approximately 11.4–12%. On $500K of earned income: approximately $57,000–$66,500 in California state tax. Florida: $0. (2) Investment income (capital gains, dividends): California taxes long-term capital gains as ordinary income at the same 13.3% top rate. There is no California preferential rate for long-term gains. A $2M capital gain from a stock sale: $266,000 in California state tax. Florida: $0. (3) Business income (S-Corp, LLC pass-through): California taxes business pass-through income at the same income tax rates. A business owner with $800K in S-Corp distributions: approximately $95,000–$106,400 in California state tax. Florida: $0. (4) The compounding effect: a high-net-worth individual with $500K salary + $300K in investment income + $200K in business income = $1M total income. California tax: approximately $133,000. Florida: $0. Over 20 years at this income level: $2.66M in cumulative California tax avoided by Florida domicile.

California-Source Income: What FL Domicile Does NOT Eliminate

Florida domicile eliminates California tax on non-California-sourced income. It does not eliminate California’s right to tax income earned in California: (1) Wages from a California employer: if a Florida resident works remotely for a California-based company, California may still claim the wages as California-source income under its “payroll factor” rules. The employer may continue withholding California income tax regardless of the employee’s FL address. This is the most common surprise for California remote workers who move to Florida. (2) California business income: income from a business with California operations, customers, or property is partially California-source regardless of where the owner lives. (3) California rental income: a Florida resident who keeps a California rental property pays California income tax on the net rental income. (4) The distinction that matters: investment income (stocks, bonds, interest) follows the taxpayer’s domicile — FL = $0 state tax. Business income follows the business’s source state — varies. Earned income follows the work location — CA employer = CA tax.

The Investment Income Windfall for Florida Movers

For high-net-worth individuals with significant investment portfolios, the Florida tax savings on investment income are often the largest single component: (1) Portfolio income: dividends, interest, and mutual fund distributions are taxed by the state of domicile. A $10M investment portfolio generating 5% in annual distributions: $500K in investment income. California tax: $66,500. Florida: $0. (2) Stock option and RSU income: complex sourcing rules apply. RSUs that vest after Florida domicile is established: California may attempt to claim the portion that vested during California employment. RSU timing around the domicile change is a significant tax planning consideration. (3) Real estate sale proceeds: if a California property is sold, the gain is California-source and California taxes it regardless of where the seller lives. The California primary residence exclusion ($250K/$500K) applies. Investment properties: California capital gains tax applies to CA property sales. After moving to Florida and acquiring Florida investment real estate: appreciation and sale of Florida properties is not subject to California income tax.

Remote Work and Florida Domicile: The Employer Nexus Problem

The fastest-growing category of California-to-Florida migrants: remote workers who can live anywhere. The tax situation is more complex than it appears: (1) If your employer is in California: California’s “source income” rules may still claim your wages if you are being paid by a California entity for services that benefit California operations. Many California employers continue withholding California income tax from employees who claim Florida addresses. Resolving this requires employer confirmation that payroll is re-sited to Florida and that California withholding has stopped. (2) If you are 1099/self-employed working for California clients: income for services performed in Florida is generally not California-source. Document where the work is physically performed. (3) If your employer is outside California: the cleanest situation. Work done in Florida for a non-California employer: Florida domicile = $0 California state tax. (4) The actionable step: confirm with a California tax attorney how your specific employment arrangement is sourced before assuming the full income tax savings apply to your situation.
