1. Start with taxable value
Not the sale price. Not always the market value.
Florida starts with just value, then assessment limits and exemptions can change the number used for tax math. Your county property appraiser shows the parcel values.
Property-tax millage
A Florida tax bill starts with taxable value and millage.
Pick a county and a taxable value. This gives you a first look at the ad valorem math, then points you back to the local offices that make it real.
Quick math
Try the millage estimate.
Millage means dollars per $1,000 of taxable value. Florida Revenue gives the basic formula as taxable value divided by 1,000, then multiplied by the millage rate.
Rough ad valorem estimate
$5,547
$300,000 / 1,000 x 18.4893 mills.
Countywide
12.3450
Aggregate/local
6.1443
Planning total
18.4893
Per $100k
$1,849
2. Read millage as a rate
One mill is $1 per $1,000.
A total millage of 18 means about $1,800 per $100,000 of taxable value before any non-ad valorem charges.
3. Check the local bill
The county page finishes the job.
Use the property appraiser for values and exemptions, then the tax collector for bills, due dates, discounts, and non-ad valorem assessments.
