How to Appeal Your Florida Property Tax Assessment
Florida mails TRIM notices in August, and the deadline to petition is printed right on the page. Miss it and you forfeit the right for a full year.
The short answer
To appeal a Florida property tax assessment, file a petition with your county Value Adjustment Board (VAB) within 25 days of the TRIM notice mailing date, usually by mid-September. The filing fee is about $15. You can also request an informal review with the property appraiser first, which is free and often faster.
What is the deadline to appeal a Florida property tax assessment?
The window
Your TRIM notice (Truth in Millage) arrives in mid-to-late August. You have 25 days from the date printed on it to file a Value Adjustment Board petition, which lands the deadline around September 12-18 depending on your county. The petition costs about $15. Miss the date and your assessed value is locked for the year.
The uncomfortable truth: most Florida owners toss the TRIM notice because it says "THIS IS NOT A BILL" at the top. That line is doing a lot of damage. It is not a bill, but it is the only official window you get to challenge the number that drives your tax bill for the entire year.
A TRIM notice is the annual statement your county property appraiser mails showing your property's assessed value, market value, exemptions, and the proposed taxes from each taxing authority. It also prints your appeal deadline in the fine print, which is the single most important date on the page.
Key takeaways
- The 25-day clock starts on the TRIM mailing date, not the day it lands in your mailbox.
- A VAB petition typically costs $15, filed with your county Clerk of Court or VAB office.
- You can appeal market value, an incorrectly denied exemption, or a portability/classification error.
- Requesting an informal review with the appraiser first does NOT extend the VAB deadline.
How to go from TRIM notice to VAB hearing
The process is more forgiving than it looks. You do not need a lawyer, and you do not need to attend a formal courtroom hearing. Most VAB hearings are informal sessions in front of a special magistrate who reviews evidence and asks questions.
- 01
1. Read the TRIM notice and find your deadline
Locate the assessed value, the market ('just') value, and the petition deadline. Compare the market value to what you believe your home would actually sell for on January 1 of the tax year. Florida assesses value as of January 1, not August, which trips up a lot of owners.
- 02
2. Call the property appraiser for an informal review
Before filing anything, phone the appraiser's office and ask to review your value. Many corrections, like a missed homestead exemption or a wrong square-footage count, are fixed here in one call for free. Do this early because it does not pause your 25-day VAB clock.
- 03
3. Build your evidence kit
Gather sold comparables near January 1, photos of condition problems, repair estimates, and for rentals an income-approach statement. The magistrate wants sold comps, not active listings. A recent purchase price below your assessed value is powerful evidence.
- 04
4. File the VAB petition (Form DR-486)
Submit online through your county Clerk/VAB portal before the deadline, pay the ~$15 fee, and choose your hearing preference. You can request the appraiser's evidence in advance; they must share it before the hearing if you ask.
- 05
5. Attend the hearing (or submit by mail/agent)
Present your comps and condition evidence in 10-15 minutes. Stay factual: 'three homes on my street sold for X on January 1.' The magistrate issues a written recommendation, and the VAB adopts it. If your value drops, your future tax bill is corrected.
The evidence kit that actually wins
Appeals fail on emotion and win on comparables. "My taxes went up too much" loses every time. "Three near-identical homes sold below my assessed value" wins. The magistrate is comparing your number to a defensible market value, so bring the market.
Checklist
0/8Bring these to your hearing
One contrarian point most guides skip: a lower market value on your TRIM does not always cut your bill. If you have homestead, the Save Our Homes cap may already hold your assessed value well below market. In that case, appealing market value changes nothing until the two converge. Check whether your assessed value, not your market value, is what's inflated. Owners of newly purchased or non-homestead property (second homes, rentals) have the most to gain because their assessed value sits at or near market.
Informal review vs. VAB petition vs. lawsuit
There are three ways to challenge your value, and they stack. Most owners should start informal, escalate to the VAB if needed, and reserve circuit court for high-dollar disputes where the VAB got it wrong.
| Path | Cost | Deadline | Best for |
|---|---|---|---|
| Informal review with appraiser | Free | Do it early; does not extend VAB deadline | Obvious errors, missed exemptions, wrong square footage |
| VAB petition (Form DR-486) | ~$15 | 25 days from TRIM date | Most owners; disputed market value or denied exemption |
| Circuit court lawsuit | Filing fees + attorney | 60 days after VAB certifies value | Large commercial or high-value disputes after losing at VAB |
The $15 VAB petition is the sweet spot for homeowners. It costs less than a pizza and forces a neutral magistrate to look at your evidence. You do not waive it by trying an informal review first, so pursue both in parallel and withdraw the petition if the appraiser fixes things on their own.
The calendar that forfeits your rights
Florida's property tax calendar is unforgiving. Every date after the TRIM notice narrows your options, and the biggest one closes 25 days after mailing. Below is the sequence homeowners need to keep on the fridge in August.
According to the U.S. Census Bureau, Florida has roughly 8 million housing units, and the vast majority of owners never file a single appeal, even in years when values jump double digits. The gap between who could appeal and who does is enormous, and it is almost entirely a calendar-awareness problem, not a merit problem.
Keeping your closing statement, prior appraisals, inspection reports, and repair receipts organized year-round is what makes an August appeal painless. This is exactly the kind of paperwork that vanishes into a junk drawer the day after closing, which is part of why platforms like One Home Agent keep a homeowner's documents and property records in one place through Danny, the document agent, so the evidence kit is already assembled when the TRIM notice lands.
Bottom line
If your TRIM notice shows a market value higher than you'd sell for on January 1, and you don't have a Save Our Homes cap holding your assessed value down, file the $15 VAB petition. It's cheap, informal, and the odds are better than the near-zero effort most owners put in.

Filing a petition with the county Value Adjustment Board costs about $15 per parcel. Requesting an informal review with the property appraiser is free. Hiring a tax agent or attorney adds cost, but most homeowners can present their own evidence at the VAB hearing without representation.
