Florida property owners successfully appeal their assessed value every year — and the process is more accessible than most people realize. In 2025, Florida Value Adjustment Boards reduced assessments on more than 40% of petitions filed. If your home's assessed value seems high, here's how to fight it and win.
Understanding Florida's Property Assessment System
Florida property taxes are based on the assessed value set by your county's Property Appraiser — an elected official, not a state employee. The Property Appraiser determines your home's "just value" (market value) each January 1st. Your taxable value is often lower, thanks to exemptions:
- Homestead Exemption: Reduces assessed value by $50,000 for primary residences.
- Save Our Homes Cap: Limits annual assessment increases to 3% or the CPI, whichever is lower — for homesteaded properties only.
- Additional exemptions: Seniors, disabled veterans, widows/widowers, and others qualify for further reductions.
Your tax bill = (Assessed Value − Exemptions) × millage rate. If the assessed value is wrong, everything downstream is wrong too.
Grounds for a Successful Florida Property Tax Appeal
You can win a Florida property tax appeal on several grounds:
- The assessment exceeds market value: The most common winning argument. If comparable homes sold for less than your assessed value, you have a strong case.
- Unequal assessment: Your home is assessed at a higher percentage of market value than comparable properties in your neighborhood. Florida law requires uniform treatment.
- Factual errors: The property record shows incorrect square footage, bedroom count, pool existence, or condition. These are easy wins — the county must correct factual errors.
- Exemption denial: The Homestead Exemption or other exemptions were wrongly denied or removed.
Step-by-Step: How to File a Florida Property Tax Appeal
Florida's appeal process has two stages — an informal review and a formal petition:
- Step 1 — Request an informal review: Call or visit your county Property Appraiser's office before the VAB petition deadline. Explain your concern. Many assessment errors are corrected at this stage without a formal hearing. No cost, no risk.
- Step 2 — File a VAB Petition: If the informal review doesn't resolve it, file a petition with your county's Value Adjustment Board (VAB). The petition fee is $15 in most Florida counties. Deadline: September 18, 2026 (25 days after the TRIM notice mailing date, typically late August).
- Step 3 — Gather your evidence: Compile comparable sales (from Zillow, Realtor.com, or the county's own deed records) showing homes like yours sold below your assessed value in the 12 months before January 1. The county must prove their value is correct — you just need to establish reasonable doubt.
- Step 4 — Attend the hearing: VAB hearings are conducted by a special magistrate. You present your evidence; the Property Appraiser defends their value. Hearings typically last 15–30 minutes. You can represent yourself — no attorney required.
- Step 5 — Receive the ruling: The magistrate issues a written recommendation; the VAB issues a final decision. If you win, your assessed value is reduced — retroactively applying to the tax year in question. Overpaid taxes are refunded with interest.
How to Find Comparable Sales for Your Appeal
The strongest evidence in a Florida property tax appeal is a list of comparable sales — similar homes that sold for less than your assessed value around January 1st of the tax year. Tips for finding strong comparables:
- Use your county Property Appraiser's website — most have a public sales search by neighborhood and property type.
- Focus on homes within 0.5 miles, similar square footage (within 15%), same bed/bath count, similar age, and similar condition.
- Aim for 3–5 comparables. More is better, but 3 strong ones beat 10 weak ones.
- If your home has significant deferred maintenance, hurricane damage, or condition issues, document these with photos and contractor estimates — they reduce market value and should be reflected in your assessment.
How Much Can You Save?
The savings depend on your county's millage rate and the size of the reduction. A rough formula: every $10,000 reduction in assessed value saves approximately $150–$250/year depending on your county. If your home is over-assessed by $50,000, that's $750–$1,250/year in tax savings — indefinitely, since the Save Our Homes cap locks in the lower base going forward.
For recently purchased Florida homes that don't yet have the Save Our Homes cap (it takes effect the year after purchase), the appeal is especially valuable — you're setting the baseline that will be capped for years to come.
Should You Hire a Property Tax Consultant?
Florida has licensed property tax agents who handle appeals on contingency — they charge 25–40% of the first year's savings if they win, nothing if they lose. This is worth considering if your potential savings are large (over $1,000/year) and you don't want to handle the process yourself. For smaller appeals, the DIY route is straightforward and the $15 filing fee is the only cost.
Key Florida Property Tax Deadlines
- TRIM Notice mailing: Mid-to-late August each year (Truth in Millage notice — your assessed value notice)
- VAB Petition deadline: 25 days after TRIM notice mailing (typically mid-September)
- Homestead Exemption application: March 1 of the year you want the exemption to apply
- Property Appraiser informal review: Any time before the VAB deadline — the earlier the better
