Calculate Jacksonville sales tax
Jacksonville sits in Duval County, Florida, where the sales tax you pay at the register combines the statewide rate with a local county surtax. The combined rate is 7.5% — Florida’s 6.0% state sales tax plus a 1.5% Duval County discretionary surtax. This calculator turns any pre-tax price into the tax owed and the final total.
How it works
The combined rate is applied to the taxable amount, and exempt items (like qualifying groceries or prescription drugs) are zeroed out:
taxable amount = exempt ? 0 : purchase amount
tax = taxable amount * (rate / 100)
total = purchase amount + tax
The default rate already merges Florida’s 6.0% state share and Duval County’s 1.5% surtax. Because surtax rates differ by county and can change by referendum, the rate field is editable for purchases made outside Jacksonville.
Tips and example
A 100 purchase at 7.5% incurs 7.50 in tax for a 107.50 total. Toggle the exemption on for a 100 grocery purchase and the tax drops to 0, keeping the total at 100.
Note that Florida’s discretionary surtax is capped at the first 5,000 of a single tangible item for business purchases, and Florida rounds small amounts using a bracket schedule, so a receipt total can vary by a cent on tiny purchases.
