Florida’s non-school property tax is the portion of your property tax bill levied by your county, your city, and any special districts your property sits in. It funds everything local government does outside of public schools: sheriff’s patrols, fire rescue, roads, parks, libraries, water management. Because the state treats non-school levies differently from school levies for homestead purposes, your tax bill shows two different taxable values for the same property, and the non-school side is usually the lower one.
Who Levies the Non-School Portion
Several independent bodies set non-school millage under Article VII of the Florida Constitution.1Florida Senate. Florida Constitution County commissions fund the sheriff, jails, county roads, courts, and general administration. City councils cover police, fire, zoning, and infrastructure inside their boundaries. Special districts handle narrower jobs like water management, fire rescue, or libraries. Municipal Service Taxing Units let a county provide city-type services to a specific unincorporated area and bill only the properties inside that area.
The Constitution caps ad valorem taxes at 10 mills for all county purposes and 10 mills for all municipal purposes. Counties that provide municipal-type services to unincorporated areas may levy additional millage within that municipal cap. Water management districts are capped at 1 mill for most of the state, and other special districts need voter approval for their millage.2FindLaw. Florida Constitution Art. VII, Section 9 These caps sit separately from school millage, so your non-school total reflects whatever combination of county, city, and special-district boundaries your property happens to fall inside.
The Extra Homestead Exemption You Only Get on Non-School Taxes
Every Florida permanent resident who homesteads their home gets a base $25,000 exemption that applies to all property taxes, school and non-school alike. A second exemption of up to $25,000 applies only to non-school taxes, and it covers the slice of assessed value between $50,000 and $75,000.3Florida Legislature. Florida Code 196.031 – Exemption of Homesteads The band between $25,000 and $50,000 gets no exemption at all, which surprises people.
Take a home with an assessed value of $100,000. The first $25,000 is exempt from every levy. The slice from $25,001 to $50,000 is fully taxable. The slice from $50,001 to $75,000 is exempt only from non-school taxes. The slice from $75,001 to $100,000 is fully taxable again. The result: a non-school taxable value of $50,000 and a school taxable value of $75,000.4Florida Department of Revenue.

The Save Our Homes Cap
Florida limits how fast the assessed value of a homesteaded property can rise. Under Section 193.155, the annual increase cannot exceed 3 percent or the change in the Consumer Price Index, whichever is lower.5Florida Legislature. Florida Code 193.155 – Homestead Assessments If CPI runs at 2 percent, your assessed value can rise only 2 percent even if the market jumps 15. The cap applies to both school and non-school levies, so it protects the whole bill.
Over the years the gap between market value and assessed value can grow large. A homeowner who bought in 2010 might have a market value of $400,000 and an assessed value under $250,000. When you sell your homestead and buy another one in Florida, you can carry up to $500,000 of that assessment difference to the new home under Florida’s portability provision. File the transfer application with the new county’s property appraiser by March 1 of the year you claim the new homestead exemption.6Florida Department of Revenue. Transfer of Homestead Assessment Difference Miss the deadline and the accumulated cap benefit is gone.
How to Calculate the Non-School Portion
One mill equals one dollar of tax per $1,000 of taxable value.7Florida Department of Revenue. A Florida Homeowner’s Guide – Millage Subtract exemptions from the assessed value to get the taxable value, then multiply by the combined non-school millage.
A homesteaded property assessed at $300,000 gets $50,000 in non-school exemptions, leaving a non-school taxable value of $250,000. If the combined non-school millage from county, city, and special districts is 15 mills, the non-school tax is $250,000 ÷ 1,000 × 15, or $3,750. The school portion is calculated the same way but starts from a taxable value of $275,000, because the extra $25,000 exemption does not apply on that side.
Your bill will also carry non-ad valorem assessments for services like solid waste pickup, stormwater, or community development. Those are flat charges, not based on value, and homestead exemptions and the Save Our Homes cap do not touch them. They sit on the same bill, which is why the total can run higher than a pure millage calculation suggests.
Your TRIM Notice and the 25-Day Clock
In mid-August most years, the county property appraiser mails a proposed-tax notice known as the TRIM (Truth in Millage) notice. Under Section 200.065, the mailing deadline is the later of 55 days after the appraiser certifies values or 10 days after the tax roll is approved.8Florida Senate. Florida Code 200.065 – Method of Fixing Millage The notice lists your market value, your assessed value after the Save Our Homes cap, and your taxable value after exemptions. It breaks out every taxing authority with its own millage, compares last year with the proposed year, and gives the dates of the public budget hearings where you can speak before rates are set.
If you think the assessed value is wrong, the notice starts a strict deadline. You have 25 days from the mailing date to file a petition with the Value Adjustment Board.9Florida Senate. Florida Code 194.011 – Assessment Notice; Objections to Assessments Miss the window and you cannot challenge the valuation for that tax year. The petition costs $15 per parcel. You will need evidence of what comparable properties sold for, independent appraisals, or photographs documenting defects. A successful challenge reduces your assessed value for both school and non-school taxes.
Paying the Bill
Final tax bills go out around November 1. Florida discounts the total for early payment:10Florida Senate. Florida Code 197.162 – Tax Discount Payment Periods
- November: 4 percent off
- December: 3 percent off
- January: 2 percent off
- February: 1 percent off
- March: full amount due
On a $5,000 bill, paying in November saves $200. Most county tax collectors accept payment online, by mail, or in person; online credit card payments usually carry a convenience fee that varies by county.
If paying the whole bill at once is a strain, Florida offers a quarterly installment plan under Section 197.222. Apply by April 30 of the year before you want to start. You make four quarterly payments based on the prior year’s tax amount and still receive a small discount on each one.
A note for mortgage holders: if your lender escrows your taxes and pays on your behalf, you generally do not capture the 4 percent November discount, because servicers batch their payments on their own schedule. If that discount matters, ask your lender whether you can waive escrow and pay the collector directly. Most lenders require at least 20 percent equity before they allow a waiver.
What Happens If You Don’t Pay
Taxes unpaid after March 31 become delinquent on April 1. Florida charges 18 percent annual interest from the date of delinquency, with a minimum charge of 3 percent even if you pay just a few days late.11Florida Legislature. Florida Code 197.172 – Interest Rate; Calculation and Minimum By June 1, the county tax collector holds a tax certificate sale. Investors bid on the right to pay your delinquent taxes in exchange for a lien, competing by offering the lowest interest rate they will accept, starting from a maximum of 18 percent.12FindLaw. Florida Code 197.432 – Sale of Tax Certificates for Unpaid Taxes If no one bids, the county takes the certificate at the full 18 percent. You still own the property, but a lien is now riding against it.
To clear the lien, you pay the full delinquent taxes plus all accrued interest. If you do not redeem within two years after April 1 of the certificate’s year of issuance, the certificate holder can apply for a tax deed and force a public auction of the property.13Florida Senate. Florida Code 197.502 – Application for Obtaining Tax Deed by Holder of Tax Sale Certificate Property tax liens take priority over mortgages in Florida, so a fully mortgaged home can still be sold at a tax deed auction if the taxes go unpaid long enough. People lose homes this way, not from a single missed payment but from letting two years go by without addressing the problem.
