In Florida, property taxes are levied by local governments (counties, municipalities, school districts, special districts) to fund essential public services like schools, law enforcement, fire protection, and infrastructure. The amount of property tax you pay is determined by two main factors: your property's assessed value and the millage rate set by each taxing authority.
How Property Taxes Are Calculated:
The calculation follows a straightforward formula:
Assessed Property Value: This is the value of your property as determined by the county property appraiser. For homestead properties, Florida law limits the annual increase in assessed value to 3% or the percentage change in the Consumer Price Index (CPI), whichever is less, thanks to the Save Our Homes amendment. For non-homestead properties, the assessed value is typically the property's just value (market value).
Homestead Exemption: Florida offers a homestead exemption, which reduces the taxable value of a primary residence. The most common homestead exemption reduces the taxable value by $25,000 for any millage levied for school purposes and an additional $25,000 for any millage levied for other purposes, up to a total of $50,000. For properties valued over $250,000, there is an additional "Save Our Homes" benefit which caps the assessed value increase.
Note: For simplicity in this calculator, we are using a simplified model and will assume a standard homestead exemption reducing the taxable value by a fixed amount if you've indicated it's a homestead. In reality, the specific calculation can be more nuanced based on the types and amounts of exemptions you qualify for. This calculator uses a representative $50,000 reduction for simplicity, assuming you qualify for at least some significant exemptions.
Millage Rate: This is the tax rate expressed in "mills." One mill is equal to $1 of tax for every $1,000 of taxable value. So, a millage rate of 15.5 means $15.50 for every $1,000 of taxable property value. Each local taxing authority (county, city, school board, etc.) sets its own millage rate. The "Total Millage Rate" is the sum of all the millage rates from the various taxing districts that apply to your property.
Example Calculation:
Let's assume:
Assessed Property Value: $300,000
Total Millage Rate: 18.5 mills
You qualify for homestead exemptions, reducing the taxable value by $50,000 (a simplified representation of typical exemptions).
Step 1: Calculate Taxable Value
Taxable Value = Assessed Value – Homestead Exemption
Taxable Value = $300,000 – $50,000 = $250,000
So, the estimated annual property tax would be $4,625.
Important Considerations:
This calculator provides an estimate. Actual tax bills may vary due to specific exemptions, special assessments, or changes in millage rates.
Always consult your local county property appraiser's office for the most accurate information regarding your property's assessed value and applicable exemptions.
Additional fees or special assessments may apply in certain communities.

// In Florida, a standard homestead exemption provides a $25,000 exemption for school district mills,
// and an additional $25,000 for other mills, up to a total of $50,000 for most properties.
// The Save Our Homes amendment caps annual assessment increases for homesteads.
// For this calculator, we'll apply a common $50,000 reduction for simplicity, assuming the user qualifies.
