Florida Homestead Exemption, Save Our Homes & Millage Explained

Why two neighbors with identical houses can pay very different property taxes in Florida, and how to estimate your own bill.

How a Florida property tax bill is calculated

Your ad valorem tax = taxable value × millage ÷ 1,000, summed over every taxing authority (county, school board, city, water management and special districts). One mill is $1 per $1,000 of taxable value. Taxable value is assessed value minus exemptions. Non-ad valorem assessments (garbage, stormwater, fire fees) are added on top and are not based on value.

The homestead exemption (2026)

Save Our Homes: the 3% cap

Once a home is homesteaded, its assessed value can rise by no more than 3% a year or the change in CPI, whichever is lower, even if the market value rises faster. Over years this creates a gap between market value and assessed value. Portability can let you transfer some of that benefit to a new Florida homestead if you apply.

The 10% non-homestead cap

For non-homestead property (second homes, rentals, commercial), assessed value increases are capped at 10% a year for non-school levies. School levies use full market value.

Why buyers often pay more than sellers did

When a home sells, the cap resets: the next January 1 the assessment moves to market value. A buyer can therefore face a much higher bill than the previous owner. Each county page on this site estimates what a new homesteaded buyer of a median-value home would pay.

Worked example

A home assessed at $350,000 in an area with 6 school mills and 12 non-school mills. With homestead: school taxable value $325,000 → $1,950; non-school taxable value $298,589 → $3,583; total $5,533. Without homestead: $6,300.

Amendment 3 (November 3, 2026 ballot)

Florida voters decide a proposed constitutional amendment on November 3, 2026. According to a Pinellas County Property Appraiser FAQ, if approved it would greatly increase the non-school homestead exemption starting in 2027, while the school-tax exemption stays at $25,000. This site's calculator reflects current (2026) law and will be updated after the vote.
