Data & Methodology

Source

County figures come from the Florida Department of Revenue, Property Tax Oversight, 2024 County Profiles (published January 2025). For each county we use total school taxable value, total county taxable value, and ad valorem taxes levied by the school district, county, municipalities and other taxing authorities.

Average effective millage

School mills = school ad valorem taxes ÷ school taxable value × 1,000.
Non-school mills = (county + municipal + other ad valorem taxes) ÷ county taxable value × 1,000.
Total = school mills + non-school mills.

Statewide, this gives 5.904 school mills and 10.459 non-school mills. County totals sum exactly to the statewide figures in the DOR report. Because municipal taxes are spread across the whole county tax base, the non-school figure is a county-wide average: homes inside high-millage cities pay more, and unincorporated homes often pay less.

Calculator assumptions

Current law: $25,000 homestead exemption on all levies, plus the additional exemption of $26,411 (2026 amount) on non-school levies for assessed value above $50,000.
Amendment 3: non-school exemption of $150,000 (2027) or $250,000 (2028) for homesteads established by December 31, 2026; $50,000 for homesteads established later, during their first four years. School exemption unchanged.
Non-homestead projection: market value grows at the rate you enter; non-school assessed value grows at the lesser of that rate and the cap (10% current, 5% proposed); school taxes use full market value.
Millage is held at 2024 averages. Local governments set new rates every year.
Not included: non-ad valorem assessments, CDD fees, other exemptions, and early-payment discounts.
