Two county offices handle your property tax. The Property Appraiser sets the value and the exemptions; the Tax Collector mails the bill and takes the money. The rates themselves are set by the county, the School Board, the city and the water management district. Bills for 2026 go out on or before Nov. 1, and paying in November earns the biggest discount.

Due dates and discounts
From the Tax Collector, for the 2026 tax bill:
| Pay by | Discount |
|---|---|
| Nov. 30, 2026 | 4% |
| Dec. 31, 2026 | 3% |
| Jan. 31, 2027 | 2% |
| Feb. 28, 2027 | 1% |
| March 31, 2027 | None: full amount due |
Taxes not paid by March 31 become delinquent April 1, 2027, when 3% is added to the gross amount. Delinquent bills are advertised in a local newspaper, and on or before June 1 the Tax Collector sells tax certificates on unpaid parcels. If your mortgage company pays through escrow, it gets the bill and you get a copy. You are still responsible for making sure the bill is paid.
Prefer to spread it out? The Tax Collector runs a quarterly installment plan. The application for next year’s plan is due April 30, and the first payment is due by June 30.
What the rate is in Kissimmee
Rates are in mills: one mill is $1 for every $1,000 of taxable value. For 2026, inside Kissimmee city limits (mill code 200), the final rates are:
| Taxing authority | 2026 mills |
|---|---|
| Osceola County (general fund 6.7, library 0.3, Save Osceola 0.25) | 7.2500 |
| School District of Osceola County | 5.2770 |
| City of Kissimmee | 4.6253 |
| South Florida Water Management District | 0.2301 |
| Total | 17.3824 |
That works out to $1,738.24 for every $100,000 of taxable value, before any special assessments on the bill. The city’s own rate has stayed at 4.6253 mills every year since at least 2020; the total has edged down mostly because the school rate fell.
A Kissimmee mailing address outside city limits pays the unincorporated county rate instead, 13.8253 mills for 2026, which has no city millage but adds a 1.0682-mill county EMS levy.

Homestead exemption
If you own your home and it is your permanent residence on Jan. 1, you can apply for the homestead exemption, worth up to $51,411 off your assessed value for tax year 2026, according to the Property Appraiser. The deadline is March 1 of the year you are applying for. Filing is free, in person or online. Bought this year? You can file now for 2027, as long as you live in the home by Jan. 1, 2027.
How to appeal your value
Each August the Property Appraiser mails a Notice of Proposed Property Taxes, called the TRIM notice. It is not a bill. If you think the value or exemptions on it are wrong:
- Call the Property Appraiser at 407-742-5000. Staff will review evidence that your market value is lower than theirs.
- If that does not settle it, file a petition with the Value Adjustment Board at the Clerk of the Board’s office, 1 Courthouse Square, Suite 4400. The fee is $15 per parcel, plus $5 for each additional parcel on a multi-parcel filing.
- The deadline is printed on your TRIM notice, and petitions are due by 5 p.m. that day. A special magistrate, independent of the Property Appraiser, hears the case.
The 2026 TRIM notices went out in August, so the petition window for this year’s values has most likely closed. Check the date on your notice.
On the Nov. 3 ballot
Florida voters will decide Amendment 3, a proposed change to homestead exemptions and non-homestead assessment limits, in the Nov. 3, 2026, general election. It needs 60% to pass. The Property Appraiser, which takes no position, says that if it passes it would take effect Jan. 1, 2027, and first show on the August 2027 TRIM notices. Its Amendment 3 FAQ explains what would change. Our voting guide has the election dates.
What this means for you
- Pay in November to save 4%; the bill should arrive by Nov. 1.
- Check your homestead exemption is on the bill. If not, file by March 1, 2027.
- Use the Property Appraiser’s tax estimator before you buy.
