- Just value: the property's market value.
- Assessed value: the value after any applicable assessment limits.
- Taxable value: assessed value minus applicable exemptions.
Each taxing authority applies its own rate, called a millage rate, to the taxable value. One mill means $1 of tax for every $1,000 of taxable value.
A worked example
Suppose a home has a taxable value of $400,000, no exemptions and a combined rate of 15 mills. These are illustrative figures, not a rate or estimate for a particular Florida home.
- Divide the taxable value by 1,000: $400,000 ÷ 1,000 = 400.
- Multiply by the millage rate: 400 × 15 = $6,000 in value-based property taxes.
- If the bill also includes $500 in separate assessments, add those: $6,000 + $500 = $6,500 for the annual bill.
This simplified example uses the same taxable value for every levy. In practice, school and non-school taxable values can differ because exemptions apply differently, so calculate each authority's charge separately and add the results.
Separate charges called non-ad valorem assessments are not based on property value. They may fund drainage, waste collection or street lighting, and homestead exemptions do not reduce them. That is why the millage rate alone does not tell you the full annual cost.
