Home & Money / Property tax

A Florida tax bill starts with taxable value and millage.

Pick a county and a taxable value to get a rough ad valorem estimate before you open the parcel record.

The useful next step is usually local: the property appraiser for values and exemptions, then the tax collector for the bill.

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.

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.

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 non-ad valorem charges, but school and non-school exemptions can make the real bill use more than one taxable value.

3. Check the local bill

The local record 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.

FAQ

Property-tax quick answers

Is this the amount I will owe?

No. This uses county-summary planning millage from the Florida Revenue workbook. Your parcel, exemptions, taxing districts, and non-ad valorem assessments can change the bill.

What number should I put in taxable value?

Use the taxable value from the county property appraiser when you have it. Sale price and market value are not always the same thing as taxable value.

Where do non-ad valorem assessments go?

They sit outside the millage calculation. Check the tax collector bill or TRIM notice for charges that are not based on property value.

Which local office should I check?

Use the property appraiser for parcel values and exemptions. Use the tax collector for bills, discounts, due dates, and payment details.
