Osceola County, FL Property Tax on a New Home: How the Bill Works and What Changes in 2027
In this article
Property tax on a new home in Osceola County, Florida, is set by the home's value on January 1, minus any exemptions, times the millage rates of every taxing authority on your bill. For 2026 bills, the county's general fund rate is 6.7000 mills. A house that was not "substantially completed" on January 1 gets no value for that year, so a new home's first bill can cover the land only, and the next one can jump. Two more changes are coming: a voter-approved one-mill school tax starting with the 2027-2028 school year, and a bigger homestead exemption on non-school taxes from Amendment 3.
How is property tax figured on a new home in Osceola County?
Three groups share the job:
The Osceola County Property Appraiser sets your home's value and applies exemptions such as homestead. Its exemptions page says Florida law lets an owner who makes the home a permanent residence "apply and receive up to a $50,000 homestead property exemption" (Osceola County Property Appraiser).
Taxing authorities each set a millage rate. One mill is $1 of tax for every $1,000 of taxable value.
The Osceola County Tax Collector sends the bill and collects the money (Osceola County Tax Collector).
Your bill adds up every rate that applies to your address. That can include the county, the school district, your city if you live in one, and special districts.
What are Osceola County's 2026 millage rates?
On September 21, 2026, the Osceola County Commission adopted its rates for the 2026-2027 fiscal year, which are the rates on the bills that go out this fall (Resolution 26-138R; Resolution 26-137R). Here are four county-level rates and what each one adds per $100,000 of taxable value:
County levy (2026 bills) | Millage rate | Tax per $100,000 of taxable value |
|---|---|---|
County general fund | 6.7000 | $670.00 |
EMS Fire/Rescue | 1.0682 | $106.82 |
Library District | 0.3000 | $30.00 |
Save Osceola Maintenance | 0.2500 | $25.00 |
These are not your whole bill. School district, city and special district rates are added on top, and not every levy applies to every address. Your TRIM notice and tax bill list the rates for your home.
Why does a new home's second tax bill jump?
The answer is one date: January 1. Florida Statute 192.042 says real property is valued "on January 1 of each year" and that "improvements or portions not substantially completed on January 1 shall have no value placed thereon" (Florida Statute 192.042).
So if your house was still being built on January 1, that year's bill may cover the land only. The next January 1, the finished house is on the roll.
Here is an example only, using just the county general fund rate of 6.7000 mills. The values are made up to show the math.
Example | Taxable value | County general fund tax |
|---|---|---|
Year 1: land only, house not finished on January 1 (example land value) | $70,000 | $469.00 |
Year 2: finished house, no homestead yet (example value) | $350,000 | $2,345.00 |
Year 2: finished house with a $50,000 homestead exemption | $300,000 | $2,010.00 |
If your mortgage has an escrow account, the lender may have estimated your taxes from that first, land-only bill. When the full-house bill arrives, the account can come up short. Our guide to escrow shortages explains what happens next.
When do you file for homestead, and when are taxes due?
Florida Statute 196.011 says a person who "on January 1, has the legal title" must file "on or before March 1 of each year." It adds that "failure to make application, when required, on or before March 1 of any year shall constitute a waiver of the exemption privilege for that year" (Florida Statute 196.011).
That makes your closing date matter:
Close by December 31: you own the home on January 1, so you can file by March 1.
Close on January 2 or later: you did not own it on January 1, so homestead waits a year.
Once a home has homestead, the Save Our Homes cap limits how much its assessed value can rise each year. The Florida Department of Revenue lists the 2026 cap as 2.7% (Florida DOR, Save Our Homes).
The Osceola County Tax Collector says bills are "normally mailed out on or before November 1st" and the discounts are:
Pay in | Discount |
|---|---|
November | 4% |
December | 3% |
January | 2% |
February | 1% |
March | None, gross amount due by March 31 |
Taxes "become delinquent on April 1st," the Tax Collector says. For the steps to apply, see how to file for the Florida homestead exemption.
What is the new Osceola County school tax?
On November 3, 2026, Osceola County voters were asked: "shall the School District of Osceola County levy an ad valorem tax of one mill for four years" for teacher and staff pay, safety and security staff, and programs such as arts, music and athletics (Osceola County Resolution 26-094R).
ClickOrlando reported on November 4, 2026, that 64% of voters approved it. The School District says the tax would be "in effect for four years beginning with the 2027-2028 school year." Its own example: a "$200,000 taxable home value would be $200 per year" (School District of Osceola County).
What does Amendment 3 change for Osceola County homeowners?
Election-night reports on November 3, 2026, said Florida voters approved Amendment 3, with WLRN reporting 62% of the vote. The state certifies official results later.
The amendment text says the homestead exemption for non-school levies is "up to the assessed valuation of one hundred and fifty thousand dollars" beginning January 1, 2027, and "two hundred and fifty thousand dollars" beginning January 1, 2028. For school district levies, it stays "up to the assessed valuation of twenty-five thousand dollars" (CS/HJR 1F, enrolled text).
There is a catch for people moving to Florida. The ballot summary says it "requires any person who establishes Florida residency after January 1, 2027," to wait for the bigger exemption, and the amendment text applies that wait to people "who had not maintained a permanent residence in this state as of December 31, 2026." For the full measure, read Florida property tax Amendment 3 explained.
What this means for new-construction buyers in Osceola County, FL
New-home buyers face a timing puzzle that resale buyers don't. Your closing date depends on when the builder finishes, and three things now line up:
January 1 decides value and homestead. A house finished after January 1 is not on that year's roll, and you must own the home on January 1 to file by March 1.
December 31, 2026, matters if you are moving from another state. Amendment 3's wait for the bigger exemption turns on your Florida residency. Ask a tax professional what counts for you.
School taxes are rising. The new one-mill school levy starts with the 2027-2028 school year, and school taxes keep only the $25,000 homestead exemption.
Before you close, ask your lender how they estimated the property tax in your escrow. If the estimate came from a land-only bill, plan for a higher payment once the finished home is taxed.

Common Questions
What is the property tax rate in Osceola County, FL?
There is no single rate. For 2026 bills, the county general fund rate is 6.7000 mills, or \$670 per \$100,000 of taxable value. School, city and special district rates are added on top, and your TRIM notice lists the ones for your address.
Why is my new home's first tax bill so low?
Florida values property on January 1. A house not substantially completed on January 1 has no value placed on it that year, so the first bill may cover the land only. The next bill includes the finished house.
When is the homestead deadline in Osceola County?
Florida law says you must own the home on January 1 and file on or before March 1. Missing March 1 waives the exemption for that year.
When are Osceola County property taxes due?
The Tax Collector says bills are normally mailed on or before November 1. You get 4% off in November, 3% in December, 2% in January and 1% in February. The gross amount is due by March 31, and taxes become delinquent on April 1.
Did Osceola County voters approve a new school tax?
Yes, ClickOrlando reported that 64% of voters approved a one-mill school tax for four years on November 3, 2026. The School District says it begins with the 2027-2028 school year, and on a \$200,000 taxable home it would be \$200 a year.
Does Amendment 3 lower school property taxes in Osceola County?
No. The bigger homestead exemption applies to non-school levies. The amendment text keeps the school-levy homestead exemption at up to \$25,000 of assessed value.
Why did my escrow payment go up after my first year in a new home?
A first-year estimate may be based on a land-only bill, because a house not finished by January 1 has no value that year. When the full house is taxed the next year, the escrow account may come up short.
