Florida Sales Tax Calculator
Note: Florida state sales tax is typically 6.000%. County discretionary surtax may apply and can change. Verify rates for official filings.
How Florida sales tax works
Florida uses a statewide base sales tax rate of 6%. On top of that, many counties add a local discretionary sales surtax. Your final rate is usually:
Total Rate = 6% state rate + county surtax rate
This means two shoppers buying the same item can pay different tax amounts depending on where the sale is sourced.
Simple formula
- Tax Amount = Purchase Amount × (Total Tax Rate / 100)
- Total After Tax = Purchase Amount + Tax Amount

Example calculations
Example 1: No county surtax
If your purchase is $100.00 and local surtax is 0.000%, your tax is $6.00 and total is $106.00.
Example 2: 1.000% county surtax
For a $250.00 purchase at 7.000% total rate, sales tax is $17.50 and total is $267.50.
Example 3: 1.500% county surtax
For a $49.99 purchase at 7.500% total rate, sales tax is about $3.75, and total is about $53.74.
Common questions
Is Florida sales tax always 6%?
The state portion is generally 6%, but your final effective rate can be higher due to county surtax.
Do all purchases get taxed?
No. Some items and transactions may be exempt, reduced, or handled differently under Florida tax rules. Always check current Department of Revenue guidance for compliance decisions.
Can I back out tax from a tax-included total?
Yes. If a price already includes tax, divide the total by 1 + (rate/100) to estimate the pre-tax amount, then subtract to get estimated tax.

- Keep the county rate updated in your POS or invoicing software.
- Round at the final tax step to avoid small cent differences.
