Full Definition
Under F.S. 201.02, the Florida documentary stamp tax on deeds and other instruments conveying real property is 70 cents for each $100 of consideration, or fractional part of it. Consideration can include money paid, obligations discharged, and mortgage amounts. Mortgages and notes carry a separate documentary stamp tax under other sections of chapter 201. Who pays is usually set by the purchase contract, so confirm it with your closing agent.
Example
On a $2,000,000 deed where consideration equals the price, the deed tax is 20,000 x $0.70 = $14,000.
Why It Matters
Doc stamps are a large line item in a Florida commercial closing and belong in both the net sheet and the buyer's cash-to-close estimate.
