Millage Rate

The unit Florida taxes are actually set in: one mill is $1 per $1,000 of taxable value.

Quick definition
A millage rate expresses property tax as mills: one mill = $1 of tax per $1,000 of taxable value. A Florida bill stacks several millages — county, school board, municipality, water management district, and any special districts — into a total. At a stacked 18 mills, a $350,000 taxable value pays $6,300 a year. Millage × taxable value is the entire equation; everything else (caps, exemptions) works on the value side.

How millages stack

No single government sets 'the' tax rate. Each taxing authority adopts its own millage at September hearings (the ones listed on your TRIM notice), and the tax collector sums them on one bill. Rates differ meaningfully between neighboring jurisdictions — crossing a city line or into a special district changes the stack.

Millage vs. what you'll actually pay

Two homes with identical millage pay very different taxes if their taxable values differ — which, in Florida, they usually do, because Save Our Homes and the non-homestead cap grow gaps between market and assessed values over time. For a purchase, estimate from millage × (your price, less exemptions), not from the seller's current bill.

Where to find yours

The property appraiser's site publishes each parcel's current millage stack, and our county property-tax pages carry verified county millages with worked examples — see the Florida property-tax hub and the estimator.

Common questions.

What does 18 mills mean in dollars?
$18 of tax per $1,000 of taxable value: on $350,000 taxable, $6,300 per year. Total millage times taxable value is the whole formula.
Why do two nearby homes have different tax rates?
Different taxing stacks — city vs. unincorporated, different special districts — or, more commonly, different taxable values under Florida's assessment caps even when the millage is identical.
Do CDD fees show up in millage?
No. CDD assessments are separate non-ad-valorem line items on the same bill — a fixed dollar amount per lot, not a rate on value. Check our CDD tables for real per-community amounts.
