No Florida State Income Tax
Florida has no state income tax. No tax on wages, no tax on capital gains at the state level, no tax on interest or dividends. For high-income earners, this is the most significant financial variable in the decision to relocate here. The difference is not marginal — it's structural.
The states most people move from tend to have among the highest income tax rates in the country. New York State taxes income above $25 million at 10.9%, but the effective rate on high earners starts well above 6% even at moderate income levels; New York City adds another 3.88%. California's top marginal rate is 13.3%, which kicks in above $1 million of taxable income and applies to all income types including capital gains. Illinois has a flat 4.95% on all income. New Jersey goes to 10.75% above $1 million. These are state-level taxes only — federal taxes apply regardless of where you live.
On $2 million of ordinary income, the Florida advantage over New York (state + city) is roughly $288,000–$296,000 per year. Over California, it's approximately $250,000–$266,000 per year. For someone with $5 million in annual income, those numbers scale proportionately. The savings are not hypothetical — they're the reason a significant share of the buyers I work with have relocated here in the past five years.
The savings on investment income are also real but more nuanced. Federal capital gains rates still apply. If you sell a business or significant asset, the federal tax — 20% long-term capital gains plus 3.8% Net Investment Income Tax — is unchanged by moving to Florida. What changes is that the state layer disappears. On a $10 million capital gain, eliminating 13.3% California state tax saves $1.33 million. That's real money, and it's the kind of event that motivates buyers to complete the residency change before a sale closes.
The Homestead Exemption
Florida's homestead exemption reduces the assessed value of your primary residence for property tax purposes. The base exemption is $25,000 applied to all property taxes, including school district taxes. An additional $25,000 exemption applies to non-school taxes for assessed values between $50,000 and $75,000. The combined effect is up to $50,000 off assessed value for non-school taxes, and $25,000 off for school taxes. In Miami-Dade County, where the millage rate runs roughly 17–19 mills depending on the municipality, a $50,000 reduction in assessed value translates to approximately $850–$950 in annual property tax savings. That's not the headline benefit — the Save Our Homes cap is.
The Save Our Homes cap limits assessed value increases to 3% per year (or the CPI increase, whichever is lower) once homestead is established. In a neighborhood like Bay Harbor Islands, Surfside, or Bal Harbour, where market values have appreciated 30–50% over the past several years, a buyer who has had homestead exemption for five to seven years is being taxed on an assessed value that may be 20–35% below current market. A neighbor who bought the same-priced unit last year pays taxes on the full current assessment. Over time this benefit compounds: the longer you hold a homesteaded property in an appreciating market, the larger the gap between your taxable assessed value and the actual market value.
To qualify, the property must be your primary residence as of January 1 of the year you apply. You file the application with the Miami-Dade County Property Appraiser's office, and the deadline is March 1 of that year. You cannot homestead a property you rent out or use primarily as a second home. If you own the property through an LLC, homestead exemption may not be available — ownership structure matters and should be part of your pre-purchase planning.
Establishing Florida Domicile
Buying real estate in Florida and calling it your primary residence are not the same thing as establishing legal domicile for tax purposes. Your prior state — especially New York and California, which have active residency audit programs for high-income earners — may contest your change of domicile if you don't execute it completely.
The steps that matter: obtain a Florida driver's license; register your vehicle in Florida; register to vote in Florida; update your will, trust, and other legal documents to reflect Florida as your domicile; change your bank account addresses and primary financial accounts to Florida; file a Declaration of Domicile with the county clerk (a public document but a clear signal of intent); and spend meaningful time here — typically a majority of nights per year, though requirements vary by state.
New York conducts statutory residency audits based on a "183-day rule" — if you maintain a permanent place of abode in New York and spend more than 183 days there in a calendar year, New York considers you a statutory resident for that year regardless of where you claim domicile. California uses a more aggressive facts-and-circumstances test that looks at where your social ties, business activities, and family are centered. Neither state will let you claim to have left without documentation. Buyers who own property in both states and split time 50/50 sometimes end up in prolonged state tax disputes. The safest approach is to actually shift your primary center of life to Florida, not just acquire a Florida address.
This is tax attorney and CPA territory. I can tell you what buyers do and what the general framework is. I cannot give you tax advice, and the specific compliance requirements for your situation depend on your income sources, your prior state's rules, and your travel patterns. If you don't already have a Florida-based tax advisor, I can refer you to practitioners I've seen work with buyers in this market.
Estate Planning Advantages
Florida has no state estate tax and no state inheritance tax. Many high-tax states — including Massachusetts, Oregon, Washington, and Maryland — impose state-level estate taxes with thresholds as low as $1 million. New York's estate tax exemption is $7.16 million (indexed for inflation), with a "cliff" provision that eliminates the exemption entirely if the estate exceeds 105% of the threshold. For New Yorkers with taxable estates in the $7–10 million range, this cliff provision is a serious planning issue. Florida has none of it.
Florida also offers strong asset protection under its homestead laws. The Florida Constitution protects an unlimited amount of equity in a homesteaded property from most creditors. This is meaningful for business owners and professionals with liability exposure — a physician, attorney, or executive who owns their primary residence in Florida and has it homesteaded retains that equity even in a judgment against them personally (with some exceptions). Florida also has favorable provisions for domestic asset protection trusts and other estate planning structures.
These benefits apply to Florida residents. Holding a vacation property in Florida while domiciled in California or New York doesn't give you Florida's estate tax advantages for your worldwide estate — your domicile state's rules govern. This is another reason why the domicile change, done properly, matters beyond just the income tax picture.
What's Overstated
The income tax benefit is significant only if you have significant income. If your primary income is Social Security, retirement distributions from accounts that were already tax-deferred, or a modest salary, the Florida tax benefit is real but smaller in dollar terms. Florida does not tax Social Security income, pension income, or retirement account distributions — but neither do most states at the low end of those distributions. The buyers for whom the tax case is most compelling are those with ongoing high earned income, active capital gains, or business income.
Property taxes in Florida are not especially low once you factor in the actual assessed value of a Miami-area condo. The millage rates in Bay Harbor Islands, Surfside, and Bal Harbour run 17–19 mills on assessed value. On a $2 million assessed condo — which is common in Bal Harbour and increasingly common in Surfside — that's roughly $34,000–$38,000 per year before the homestead exemption applies. Once homesteaded and with the Save Our Homes cap in effect for a few years, that number becomes more favorable, but buyers expecting Florida to mean low property taxes can be surprised by the first year's tax bill before homestead kicks in.
The sales tax on goods and services is 7% in Miami-Dade County. There's no income tax but there is a real consumption tax. Buyers who move here from states without sales tax (Oregon, Montana, New Hampshire) will notice this more than those coming from California or New York, where sales taxes are already high.
Tamara's Practical Advice
The buyers I've seen make this work cleanly are the ones who treat the move as a complete transition, not a hedge. You either change your domicile or you don't. Attempting to capture the Florida tax benefit while maintaining your full life infrastructure in New York or California invites audit and frequently doesn't hold up. The buyers who do it fully — driver's license changed, voter registration changed, legal documents updated, time actually spent here — don't have problems. The ones who do it halfway sometimes spend years in state tax disputes that cost more than the benefit they were claiming.
Before you buy, talk to a CPA or tax attorney who specializes in multi-state domicile changes. Not all CPAs are familiar with the nuances of California or New York residency audits — you want someone who has defended clients through that process, not just one who filed returns in both states. I can refer you to practitioners I've seen work effectively with buyers in this situation.
The real estate decision and the tax strategy decision intersect but aren't the same decision. I'll help you find the right property in the right building. The question of whether to hold it personally, through a trust, through an LLC, or through some other structure is a question for your estate attorney before you close. Getting the ownership structure right at purchase is much cleaner than unwinding it afterward.
