Osceola County Florida Property Tax Appeal Guide 2027
Osceola County property tax appeal guide 2027. Kissimmee, St. Cloud, and Celebration homeowners: challenge your TRIM assessment before the 25-day deadline. TaxAppeal USA: $89 ready-to-sign kit.
Osceola County is defined by its relationship to tourism — Walt Disney World, Universal, and the broader Orlando theme park corridor sit largely within or adjacent to the county. This creates one of Florida's most complex property assessment environments: a mix of primary residents, short-term vacation rentals, timeshares, and commercial hospitality properties all assessed by the same Osceola County Property Appraiser. Kissimmee and St. Cloud serve as the county's primary residential cities, while Celebration (a Disney-designed master-planned community) and Poinciana (spanning Osceola and Polk counties) add further diversity. The 2027 TRIM season opens in August.
Osceola County Market Conditions
Osceola County's short-term rental market creates particularly complex assessment dynamics. Investment properties used as vacation rentals near Disney are assessed at full market value annually with no Save Our Homes cap. Their high purchase prices and rental income potential drive up comparable sale data, which can inflate assessments for adjacent primary residences. Separating investor-driven sales from owner-occupant comparable sales is essential for a strong Osceola County appeal.
✓Kissimmee: Largest Osceola city; strong primary resident community adjacent to tourism corridor; over-assessments common
✓St. Cloud: Growing east Osceola community with strong primary resident market and correction from 2022 peak
✓Celebration: Disney-designed planned community; premium pricing with tight comparable set
✓Poinciana: Large affordable community spanning Osceola/Polk; rapid growth creates assessment inconsistencies

We check first whether a petition will lower your bill after Save Our Homes and your exemptions; if it won't, we tell you and don't sell you one.

You sign it, add a cheque for the county's filing fee (paid by you, to the county), and mail it the day it arrives. Flat $89.

Frequently Asked Questions
Does TaxAppeal serve Kissimmee and St. Cloud? ▾
Yes. TaxAppeal USA serves all Osceola County communities including Kissimmee, St. Cloud, Celebration, Poinciana (Osceola portion), Buena Ventura Lakes, and all unincorporated areas.
Can I appeal my Kissimmee vacation rental property taxes? ▾
Yes. Non-homestead vacation rentals are assessed at full market value annually. If your property is over-assessed relative to comparable sales, a VAB petition can reduce your assessed value and annual tax obligation.
When do Osceola County TRIM notices arrive? ▾
Typically mid-August. Your deadline is 25 days from the mailing date on your notice.
How do investor sale prices affect my primary residence assessment? ▾
The Osceola County Property Appraiser uses all sales data, including investor transactions near Disney, to calibrate market values. These investor sales often occur at premium prices that do not reflect the market for owner-occupied homes. Documenting that your home is a primary residence and using owner-occupant comparable sales strengthens your petition.
What is the Osceola County VAB filing fee? ▾
$50 per petition, payable to Clerk of the Court. You pay it to the county with a cheque you put in the envelope with your petition; it is not part of our $89 fee. The county's fee is not refundable, so we check whether an appeal can lower your bill before you pay.
How much can Osceola County homeowners save? ▾
A typical successful appeal reduces assessed value by $15,000-$35,000, saving $210-665 per year at Osceola County rates.

TaxAppeal USA is a self-service document-preparation service. We prepare a ready-to-sign appeal kit and mail it to you; you sign it and mail it to the county yourself. In every state we serve, including Florida, we are not property tax consultants, agents, or representatives, we do not provide tax or legal advice, and we do not file appeals or represent customers before any appraisal district, board of assessors, board of equalization, value adjustment board, or review board. Every appeal, protest and petition is prepared for the property owner, signed by the owner, and mailed by the owner in the owner’s name. In Florida your petition is signed by you as the property owner under section 194.011(3), Florida Statutes, and the county’s Value Adjustment Board filing fee is paid by you directly to the county. TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
