Calculate Tampa sales tax
Tampa sits in Hillsborough County, Florida. Purchases there carry a 7.5% combined sales tax: Florida’s 6% statewide rate plus a 1.5% 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) are zeroed out:
taxable amount = exempt ? 0 : purchase amount
tax = taxable amount * (rate / 100)
total = purchase amount + tax
The default 7.5% merges Florida’s 6% state tax and the 1.5% Hillsborough County surtax. Because surtax rates can change by referendum and differ in neighboring counties, the rate field is editable.
Tips and example
A 100 purchase at 7.5% incurs 7.50 in tax for a 107.50 total. Toggle the grocery exemption on for a 100 unprepared-food purchase and the tax drops to 0, keeping the total at 100.
Remember that Florida caps the discretionary surtax on the first 5000 of any single tangible item, so very large purchases pay slightly less than the flat 1.5% surtax would suggest.
