The Osceola County property tax rate for 2025 is approximately 13.8543 mills in the unincorporated areas, about 17.4114 mills inside Kissimmee, and about 17.8989 mills inside St. Cloud. A mill equals $1 of tax for every $1,000 of taxable value, so the unincorporated rate works out to roughly $13.85 per $1,000.1Osceola County Property Appraiser. 2025 Final Millage Rates City residents pay more because their municipal millage stacks on top of the countywide levies. New rates are adopted each fall after public budget hearings, so 2026 figures may shift.
What Makes Up the Rate
Every property in the county is hit by several overlapping levies. The 2025 countywide pieces are:
- County levies totaling 7.2500 mills: general fund (6.7000), library district (0.3000), and Save Osceola (0.2500). Adding EMS brings the broader county operating rate to about 8.0682 mills.
- School district: 5.3060 mills, split among required local effort (3.0580), discretionary operating (0.7480), and capital outlay (1.5000).
- South Florida Water Management District: 0.2301 mills, covering the district-wide assessment, Okeechobee Basin, and Everglades construction.
Those apply everywhere in the county. Live inside a city or a special district and more is added. Properties within the Central Florida Tourism Oversight District, for example, carry an additional 12.4236 mills on top of countywide levies.1Osceola County Property Appraiser. 2025 Final Millage Rates Each parcel is assigned a millage code showing the exact combination of taxing districts that serve it. You’ll find that code on your TRIM notice and tax bill, and the Property Appraiser publishes the full schedule each year.
Turning the Rate Into a Dollar Amount
The millage rate doesn’t get applied to your home’s market value. The Property Appraiser first determines market value from recent comparable sales and local conditions, then subtracts the assessment caps and exemptions you qualify for to arrive at taxable value. Only then does the millage rate come in.
Take a home with a market value of $350,000. With a $50,000 homestead exemption and a Save Our Homes cap holding the assessed value to $280,000, taxable value lands at $230,000. At the unincorporated rate of 13.8543 mills, that produces roughly $3,186 in ad valorem taxes. Your actual bill will also carry non-ad valorem assessments, which are flat fees for things like solid waste, stormwater, or street lighting that don’t depend on value.
Exemptions That Lower What the Rate Applies To
Homestead Exemption
If you own and permanently reside in your Osceola County home as of January 1, you can apply for a homestead exemption that removes up to $50,000 from taxable value. The first $25,000 applies against every taxing authority, including the school district. The second $25,000 applies only to assessed value above $50,000, and it doesn’t apply to school levies.2The Florida Legislature. Florida Statutes 196.031 – Exemption of Homesteads Assessed value between $25,000 and $50,000 gets no exemption at all, which surprises some owners.
The filing deadline is March 1 of the tax year. Osceola accepts applications online. You’ll need a Florida driver’s license or state ID, your Social Security number, and proof that the property is your permanent residence as of January 1.3Florida Department of Revenue.

Save Our Homes Cap
With a homestead in place, your assessed value is protected by the Save Our Homes cap. Each January 1 the Property Appraiser reassesses, but any increase is limited to 3% or the change in the Consumer Price Index, whichever is lower.4The Florida Legislature. Florida Statutes 193.155 – Homestead Assessments Over years, this can produce a sizable gap between market value and the assessed value used for taxes. If you sell and buy a new Florida homestead, you can transfer up to $500,000 of that accumulated savings to the new home by filing Form DR-501T by March 1, and you must establish the new homestead within three years of giving up the old one.5Florida Department of Revenue.

Senior Exemption
Homeowners age 65 or older whose total household income falls below the annual state threshold may qualify for an additional exemption of up to $50,000. For 2026, that household income limit is $38,686.6Florida Department of Revenue. Additional Homestead Exemptions for Persons 65 and Older Household income includes everyone living in the home and counts Social Security, pensions, and investment earnings. Osceola County has adopted the exemption by ordinance.
Disabled Veteran Exemptions
Florida veterans can stack additional benefits on top of the standard homestead:
- A $5,000 reduction from assessed value for honorably discharged veterans with a service-connected disability rating of at least 10%, which also extends to an unremarried surviving spouse.7The Florida Legislature. Florida Statutes 196.24 – Exemption for Disabled Ex-Servicemember or Surviving Spouse
- A complete exemption from ad valorem taxes on the homestead for veterans with a total and permanent service-connected disability, with no cap on home value and no income test. An unremarried surviving spouse keeps the exemption for life.8The Florida Legislature. Florida Statutes 196.081 – Exemption for Certain Permanently and Totally Disabled Veterans
- A percentage discount on ad valorem taxes for combat-disabled veterans age 65 and older equal to their VA disability rating. A 70% rating produces a 70% reduction. Applications require a VA letter, honorable discharge documentation, and proof of age, filed by March 1.9The Florida Legislature. Florida Statutes 196.082 – Discounts for Disabled Veterans
When to Pay, and the Early-Pay Discount
Bills go out on or before November 1, and Florida rewards early payment:10Osceola County Tax Collector. Real Estate Taxes
- November: 4% discount
- December: 3% discount
- January: 2% discount
- February: 1% discount
- March: full amount, no discount
On a $4,000 bill, paying in November instead of March saves $160.11The Florida Legislature. Florida Statutes 197.162 – Tax Discount Payment Periods The Tax Collector accepts e-check or credit card online, mail payments, and in-person payments.
If paying the full amount at once is a problem, Florida offers a quarterly installment plan. You must apply by April 30, and your estimated tax must exceed $100. Payments are due June 30, September 30, December 31, and March 31, with discounts of 6%, 4.5%, 3%, and none, respectively. Miss the first June 30 payment and you’re off the plan for the year.12The Florida Legislature. Florida Statutes 197.222 – Prepayment of Estimated Tax by Installment Method
If You Think the Rate or Value Is Wrong
Each summer, the Property Appraiser mails every owner a Truth in Millage (TRIM) notice showing the proposed rates from each taxing authority and the resulting dollar amounts.13The Florida Legislature. Florida Statutes 200.069 – Notice of Proposed Property Taxes The rate itself is set by the taxing authorities at their budget hearings and isn’t something you can appeal, but the assessed value is. If you think your value is wrong, you have 25 days from the date the TRIM notice is mailed to file a petition with the Value Adjustment Board. For a denied exemption, the window is 30 days.14My Florida Legal. Value Adjustment Board, Petition Filing Deadlines
Before petitioning, call the Property Appraiser’s office. Many valuation disputes get resolved informally when an owner points out a missed comparable sale or a data error on the property record. If you do go before the board, bring concrete evidence: recent comparable sales, a private appraisal, or documentation of defects the appraiser may not have accounted for.
