Homestead Exemptions and Property-Tax Math

Calculate school taxes and non-school taxes separately whenever their exemptions differ. Subtract the exemptions that apply to each tax, multiply each taxable value by its own millage rate, and then add the taxes.

Florida rules checked October 18, 2026. The examples are original study exercises. They assume the owner qualifies for the stated exemptions and omit non-ad valorem assessments and early-payment discounts.

Start with the tax year

The basic homestead exemption covers the first $25,000 of assessed value for school and non-school property taxes. The additional homestead exemption applies only to non-school taxes and to assessed value above $50,000. Beginning in 2025, that additional amount is adjusted for positive inflation. See Florida Statutes §196.031.

These are maximums, not automatic deductions from every property's value. The Florida Department of Revenue's annual table supplies the inflation-adjusted amounts. In 2026, the full additional amount requires at least $76,411 in assessed value. The basic school-tax exemption remains $25,000.

Turn mills into a tax rate

One mill = $1 per $1,000 of taxable value = 0.001.
Tax = taxable value × mills ÷ 1,000.

For example, 6 mills is 0.006, not 0.06. If city and county taxes use the same taxable value, you can combine their millage rates. Do not combine school and non-school rates before accounting for their different exemptions.

Example 1: School and non-school taxes

Given: For 2026, a qualifying homestead has an assessed value of $180,000. School millage is 6; the combined non-school millage is 15. No other exemptions apply.

Total tax = $2,858.84. Round the tax amounts to cents. Using $51,411 against school taxes would overstate the exemption.

Example 2: A property below the full additional-exemption threshold

Given: A qualifying 2026 homestead has an assessed value of $60,000 and no other exemptions.

Only $10,000 of its value lies above $50,000. Its additional exemption is therefore $10,000, not $26,411.

• School taxable value: $60,000 − $25,000 = $35,000.
• Non-school taxable value: $60,000 − $25,000 − $10,000 = $25,000.

Example 3: Adding qualifying personal exemptions

The exemptions under §196.202 include $5,000 for a qualifying widow or widower and $5,000 for a qualifying blind person. They are not the old $500 amounts. Eligibility matters; do not assume every homeowner qualifies.

Rule 12D-7.003 allows a person who qualifies in more than one classification to combine those exemptions, subject to its limits. This does not mean every exemption in Florida can be stacked without restriction.

Given: Use Example 1, but the owner also qualifies for both the $5,000 widow exemption and the $5,000 blind exemption, applicable to both tax groups.

• School: ($180,000 − $25,000 − $10,000) × 0.006 = $870.00.
• Non-school: ($180,000 − $51,411 − $10,000) × 0.015 = $1,778.84.

Total tax = $2,648.84. The two additional exemptions save $10,000 × (0.006 + 0.015) = $210 compared with Example 1.

Taxes owed and tax savings are different answers

In Example 3, tax with no exemptions would be $180,000 × 0.021 = $3,780. Total savings from all stated exemptions is $3,780 − $2,648.84 = $1,131.16. The tax owed is $2,648.84. Circle which one the question requests.

Try it yourself

1. A qualifying 2026 homestead is assessed at $100,000, with no other exemptions. School millage is 5 and non-school millage is 10. What is the total tax?
2. A practice problem expressly gives an additional $5,000 exemption that applies to both school and non-school taxes. Their combined rate is 18 mills, and sufficient taxable value remains. How much tax does that additional exemption save?
3. A 2026 homestead is assessed at $45,000, with no other exemptions. What are its school and non-school taxable values?

Answers and explanations

1. $860.89. School: $75,000 × 0.005 = $375. Non-school: $48,589 × 0.010 = $485.89. Add the taxes after using the correct exemptions.
2. $90. $5,000 × 0.018 = $90. The exemption removes taxable value; it does not subtract $5,000 from the tax bill.
3. $20,000 for each. $45,000 − $25,000 = $20,000. No assessed value lies above $50,000, so no additional homestead exemption applies.

If an older question gives a different answer

Check the stated tax year, assessed value, approved exemptions, and the requested result. A historical exercise may legitimately use that year's amounts. If no year is given and the answer relies on outdated amounts, flag it for review rather than changing the arithmetic to fit an answer choice. See My Textbook, PDF, or Practice Question Seems Wrong.
