School taxes in Florida are calculated by multiplying your property’s taxable value by the combined school millage rate set for your county. Taxable value is your assessed value minus any exemptions that apply to school taxes, and the millage rate is a stack of separate levies added together. Both sides of that equation have rules that can shift your bill by hundreds or thousands of dollars, so it’s worth knowing what goes into each one.
How Your School Tax Is Calculated
A “mill” equals $1 of tax per $1,000 of taxable value. To find your school tax, divide your taxable value by 1,000 and multiply by the total school millage rate.
Say your home has a taxable value of $250,000 for school purposes, and your county’s combined school millage is 6.500 mills:
$250,000 ÷ 1,000 = 250
250 × 6.500 = $1,625 in school taxes
The number that matters most here is the taxable value, not the market value of your home. Exemptions reduce it. The Save Our Homes cap can hold it well below market value for long-time homeowners. Those two factors are where most of the real savings live.
What Makes Up the School Millage Rate
The school portion of your tax bill is not a single levy. It’s up to four separate components, each set through a different process.
Required Local Effort
The Required Local Effort is the millage every Florida school district must levy to receive state funding through the Florida Education Finance Program. For the 2025–26 fiscal year, the statewide RLE millage is 3.092 mills.1Florida Department of Education. 2025-26 FEFP Third Calculation No district opts out; the Legislature sets it, and every district levies it.
Discretionary Operating Millage
School boards may levy an additional operating millage without going to voters. The Legislature sets the maximum allowable rate each year in the appropriations act.2Florida Legislature. Florida Code 1011 – Section 1011.71 Most districts levy at or near the cap, and this typically appears as its own line on your bill.
Voter-Approved Operating Millage
Some districts ask voters to approve extra operating millage through a referendum. By statute, voter-approved operating millage lasts a maximum of two years before it must go back on the ballot.3Florida Legislature. Florida Code 200 – Section 200.001 If your district passed a referendum recently, that portion of your school tax will disappear unless voters renew it.
Capital Outlay Millage
A separate levy under Section 1011.71 funds construction, renovations, and technology infrastructure rather than teacher salaries or day-to-day operations. Not every district levies the same amount, and it’s a distinct line from the operating millages above.
The Homestead Exemption and School Taxes
If your home is your primary residence and you file for the Florida Homestead Exemption, the first $25,000 of the exemption reduces the taxable value used for all property taxes, including school taxes.4Florida Department of Revenue. Florida Homestead Property Tax Exemption
There is also an additional exemption that applies to assessed value between $50,000 and $75,000, worth up to $26,411 for 2026 after inflation adjustment.5Florida Department of Revenue. Additional Homestead Exemption Adjustment This second tier does not apply to school district taxes.4Florida Department of Revenue. Florida Homestead Property Tax Exemption It lowers what you owe to your county, city, and special districts, but your school tax calculation only benefits from the first $25,000.
Take a home assessed at $300,000. For school tax purposes, the taxable value is $275,000. For everything else on your bill, the taxable value is lower still because the additional exemption also applies.
The deadline to file for homestead exemption is March 1 of the tax year. Miss it and you lose the exemption for that entire year. If you recently bought a home or moved, get the application in with your county property appraiser as early as possible.
Senior Exemptions Don’t Lower School Taxes
Florida counties and cities may grant additional homestead exemptions to residents age 65 and older with household income below an annually adjusted threshold ($38,686 for 2026). These can be worth up to $50,000 in reduced assessed value, and qualifying long-term homeowners may receive an exemption equal to the entire assessed value of their property. None of these senior exemptions apply to school district millage.6Florida Department of Revenue. Two Additional Homestead Exemptions for Persons 65 and Older Your county and city taxes drop; your school taxes don’t.
The Save Our Homes Cap
Once your home has its homestead exemption and has been assessed at market value in the first year, Save Our Homes caps the annual increase in assessed value at 3% or the change in the Consumer Price Index, whichever is lower.7Florida Senate. Florida Code 193 – Section 193.155 In a year when your home’s market value jumps 15%, the assessed value used for your school tax bill still only rises by the capped amount.
Over time this creates a gap between market value and assessed value that keeps widening. A homeowner who bought in 2010 might own a home worth $500,000 on the open market but assessed at $280,000 for tax purposes. Every mill of school tax is calculated against that lower number.
The cap can still push your assessed value up in a year when market prices fall, as long as the increase stays within the annual limit.8Florida Department of Revenue. Save Our Homes Assessment Limitation and Portability Transfer If market value drops below your capped assessed value, though, the assessed value has to come down to match. It’s a ceiling, not a floor.
Taking the Savings With You: Portability
When you sell your homesteaded home and buy another one, portability lets you transfer up to $500,000 of the difference between your old home’s market value and its assessed value to the new property.7Florida Senate. Florida Code 193 – Section 193.155
To qualify, you must have received a homestead exemption on your previous home within any of the three tax years immediately before establishing the new homestead.7Florida Senate. Florida Code 193 – Section 193.155 If your new home costs more than your old one, you transfer the full dollar amount of accumulated savings up to the $500,000 cap. If the new home costs less, the benefit is proportionally reduced. File for portability with your county property appraiser at the same time you file for homestead on the new property, by the same March 1 deadline.
Without portability, someone with $150,000 in accumulated Save Our Homes savings would watch their school tax bill spike overnight after a move, because the new home starts fresh at market value.
Your TRIM Notice
Every summer, before your tax bill is finalized, your county property appraiser mails you a Notice of Proposed Property Taxes, known as the TRIM notice (Truth in Millage). It shows your assessed and taxable values, the proposed millage rates from every taxing authority including the school district, and the dollar amount each authority plans to collect from you.
The TRIM notice is not a bill. It’s a preview and a chance to act. If you think your assessed value is wrong, you can file a petition with the Value Adjustment Board within 25 days of the date the property appraiser mailed the notice. The notice also lists the public hearings where the school board will vote on its final millage rates. Those hearings are open, and attending is the direct way to push back on what the school portion of your bill will be.
What Happens If You Don’t Pay
Property taxes in Florida, including the school portion, become delinquent on April 1 of the year after they’re assessed. All property taxes create a first lien on the property that outranks mortgages and other claims.9Florida Legislature. Florida Code 197 – Section 197.122 If the bill stays unpaid, the tax collector sells tax certificates on the property at public auction, with investors bidding down the interest rate the delinquent owner will owe on redemption.10Florida Senate. Florida Code 197 – Section 197.432
The certificate holder cannot contact you or pressure you to pay for two years after April 1 of the year the certificate was issued.10Florida Senate. Florida Code 197 – Section 197.432 After that, the certificate holder may apply for a tax deed, starting a process that can end in the sale of your home. The timeline runs in years, not months, but the lien keeps accruing interest and fees the whole time.
