When real estate changes hands in Florida the state collects a documentary stamp tax on the deed. This calculator applies the per-$100 rate for your county — including Miami-Dade’s lower deed rate and its non-single-family surtax — to the sale price and shows the exact tax owed.
How it works
Florida’s documentary stamp tax on a deed is charged per 100 dollars of consideration, with the price rounded up to the next full 100. The rate is:
- $0.70 per $100 (0.70%) in every county except Miami-Dade.
- $0.60 per $100 (0.60%) on the deed in Miami-Dade County.
Miami-Dade additionally imposes a surtax of $0.45 per $100 on transfers of property that is not a single-family residence (for example, condos, duplexes, or commercial property).
The core formula is:
units = ceil(price / 100)
tax = units × rate_per_100 (+ units × 0.45 if Miami-Dade non-single-family)
Example
A 400,000 dollar single-family home sold outside Miami-Dade rounds to 400,000 (4,000 units of 100). At 0.70 dollars per unit the documentary stamp tax is 2,800 dollars. The same home in Miami-Dade pays 4,000 × 0.60 = 2,400 dollars and, being single-family, owes no surtax.
Notes
This estimates only the deed documentary stamp tax. Florida also levies doc-stamp tax on mortgage notes (0.35% of the note) and a one-time intangible tax on mortgages (0.20%), which buyers usually pay separately. Who pays the deed tax is set by contract custom and can be negotiated. Confirm current rates with the Florida Department of Revenue (Form DR-15) and your county clerk.
