Frequently Asked Questions
What Florida property tax rate is used here?
The statewide estimate uses Florida Department of Revenue 2025 final taxes levied divided by 2025 taxable value: about 0.6563% for school taxes and 1.0449% for non-school taxes before homestead exemptions. County pages override those rates with DOR county millage data.
How does Florida homestead affect this calculator?
For a qualifying primary residence, the first $25,000 exemption reduces both school and non-school taxable value. A second $25,000 exemption reduces only non-school taxable value. The Save Our Homes cap then limits annual assessed-value growth for continuing homesteads.
What Florida closing taxes are included?
The estimate includes deed documentary stamp tax on the sale price, mortgage documentary stamp tax on the loan amount, and nonrecurring intangible tax on the mortgage obligation. County files can override rates where Florida law differs, such as Miami-Dade deed documentary stamp tax.
What Pinellas County property-tax benchmark is used?
This county page uses Florida DOR's 2025 county millage data, split into school and non-school components for the Florida homestead exemption calculation.
