Florida has no state income tax, which means you pay $0 in state capital gains tax when selling your home. This zero-tax advantage is one of the primary reasons Florida has become the top destination for retirees and high-net-worth individuals from high-tax states like New York, New Jersey, and California.
While Florida offers a complete state tax shield, federal capital gains obligations remain. Most sellers owe 15% federal long-term capital gains tax on any gain exceeding the $250K/$500K exclusion, plus potentially the 3.8% NIIT if their modified adjusted gross income exceeds $200K (single) or $250K (married).
Florida does impose documentary stamp tax on real estate transactions, which is effectively a transfer tax. The rate is $0.70 per $100 of the sale price (higher in Miami-Dade County at $0.60 plus a surtax). On a $400,000 sale, this amounts to approximately $2,800. While not a capital gains tax, it is a selling cost that reduces your net proceeds.
For individuals relocating to Florida from high-tax states specifically to avoid capital gains tax on a future sale, be aware that establishing Florida domicile requires genuine intent and physical presence. Simply buying a Florida property while maintaining a primary residence in another state will not shield the sale of the non-Florida property from that state's taxes.
