Florida’s 0% Advantage on Capital Gains

Florida is one of nine states with no personal income tax. Article VII, Section 5 of the Florida Constitution prohibits a state personal income tax entirely. This isn’t a temporary policy or a legislative choice that could flip in the next session. It’s baked into the constitution and would require a voter referendum to change.

For capital gains specifically, this means a Miami resident who sells $2 million in appreciated stock pays $0 to the state. A California resident with the same sale pays roughly $266,000 to Sacramento. A New York City resident pays about $295,000 to Albany and City Hall combined. That’s not a rounding error. It’s a house.

Side-by-Side: Miami vs. LA vs. NYC

Take a $1 million long-term capital gain and compare the total tax burden across all three cities. Federal taxes are identical regardless of location, so the difference comes entirely from the state and local layer.

• Miami (Florida): 20% federal + 3.8% NIIT = 23.8% total — roughly $238,000
• Los Angeles (California): 20% + 3.8% + 13.3% state = 37.1% — roughly $371,000
• New York City: 20% + 3.8% + 10.9% state + 3.876% city = 38.576% — roughly $385,760

The Miami investor keeps $133,000 more than the LA investor and $147,760 more than the NYC investor on the same $1 million gain. On a $5 million startup exit, that gap widens to $665,000 and $738,800 respectively. These aren’t theoretical savings. They’re the reason you see California license plates in Brickell parking garages.

Federal Taxes Still Apply

Living in Miami doesn’t eliminate capital gains tax. It eliminates the state portion. Federal long-term capital gains rates (0%, 15%, or 20% based on income), the 3.8% NIIT, and any depreciation recapture at 25% all apply identically whether you live in Coral Gables or Calabasas.

For most high-income Miami investors, the effective federal rate on long-term gains is 23.8% (the 20% top rate plus 3.8% NIIT). That’s still real money. But compared to the 37%+ all-in rate in California or New York, it’s a significantly better outcome.

Short-term gains (assets held under one year) are taxed as ordinary income at the federal level, with rates up to 37%. No state tax in Florida, but the federal bite on a short-term gain is still steep. Holding for at least 366 days before selling remains one of the simplest planning moves available.

Relocating to Miami Before a Sale

The tax savings are so large that many California and New York investors consider relocating to Florida before a major liquidity event. This works, but only if the move is genuine. Both California and New York will audit a residency change that happens suspiciously close to a large asset sale.

California’s Franchise Tax Board is the most aggressive. They examine cell phone GPS data, credit card transactions, veterinary records for pets, gym membership usage, and social media check-ins. A typical residency audit reviews 18+ months of activity. Simply signing a Miami lease and changing your mailing address won’t hold up.

New York’s Department of Taxation applies the “domicile” and “statutory residency” tests. If you spend 184 or more days in New York and maintain a permanent place of abode there, New York considers you a resident regardless of where you claim domicile. Selling a New York apartment or breaking a lease before the move strengthens your case considerably.

The safest approach: move to Miami at least a full tax year before the sale. Establish genuine ties — Florida driver’s license, voter registration, doctors, church or community involvement, kids enrolled in local schools. The more roots you put down, the harder it is for California or New York to argue you never really left.

What Miami Investors Should Still Plan For

No state tax doesn’t mean no planning is needed. Federal estimated tax payments are still required quarterly if you expect to owe $1,000 or more. Underpayment penalties apply at the federal level just as they would anywhere else.

The estate tax is another area where Florida provides an advantage. Florida has no state estate tax. But the federal estate tax (40% on estates above $13.61 million per individual in 2024) applies regardless of domicile. Stepped-up basis at death eliminates the capital gains tax on appreciated assets that pass through an estate, which makes holding versus selling a meaningful planning decision for wealthy Miami families.

For real estate investors, Florida’s homestead exemption offers unlimited asset protection from creditors (with some timing restrictions). Combined with no state capital gains tax, this makes Florida one of the most favorable states in the country for building and protecting wealth through real estate.
