Florida commercial and multifamily assessments are set by mass appraisal — the county never looks at your rent roll, your vacancy, or your deferred maintenance. When the assessed value exceeds real market value, you overpay every single year.

1. The TRIM notice.Every August, the Property Appraiser mails a Truth in Millage (TRIM) notice showing your proposed assessed value for the year. This is not a bill — it’s your one warning before the assessment becomes final.
2. The 25-day window. From the TRIM mailing date, you have 25 days to petition the county Value Adjustment Board (form DR-486). Miss it, and the assessment stands for the entire tax year.
3. The evidence. A successful appeal shows the assessed value exceeds market value — usually with an income analysis (rent roll → NOI → capitalized value) and comparable sales. This is where most self-filed petitions fail.
4. The hearing. Petitions are heard by a special magistrate in fall–winter. Many resolve earlier through an informal conference with the Property Appraiser. If the value drops, your tax bill drops with it.
