Round the number of taxable $100 units upward, then multiply by the applicable rate. Do not round the final tax to the nearest dollar. The Florida Department of Revenue states that a partial $100 counts as another taxable unit.

Here is an original example using a taxable cash sale with $286,350 of consideration, no exemption, and no additional consideration. Dividing $286,350 by $100 gives 2,863.5, so use 2,864 units.

• Outside Miami-Dade: 2,864 multiplied by $0.70 gives $2,004.80.
• Miami-Dade, transferring only a single-family dwelling: 2,864 multiplied by $0.60 gives $1,718.40. The county surtax does not apply to this category.
• Miami-Dade, a taxable commercial transfer: the $0.60 base tax plus the $0.45 surtax gives $1.05 per unit. The total is $3,007.20.

The house example is not a blanket exception for every transaction involving residential property. The Department's wording concerns a document transferring only a single-family dwelling. A transfer involving other property or a different ownership arrangement needs its own review.

Also, consideration is not necessarily just the cash handed over at closing. Assumed debt and other value can matter. First identify the taxable consideration and property category; only then do the arithmetic. A buyer-seller agreement about who pays does not determine whether tax is due.

These figures are study examples, not a closing quote. Check the Department of Revenue's documentary stamp guidance for the transaction's rules and exemptions. For more worked calculations, see our Florida closing math guide.
