What is the Florida TRIM notice and why does it matter for my property tax appeal?

In Florida the TRIM notice — formally the Notice of Proposed Property Taxes and Non-Ad Valorem Assessments — is the single most important document in your appeal. County property appraisers mail it each year, typically in mid-to-late August, under Fla. Stat. §200.069. It is not a bill; it is a proposed-tax notice, but it is the document the law builds the appeal deadline around.

What it shows. The TRIM notice lists, for both the prior year and the current year, your parcel's just (market) value, assessed value, exemptions, and taxable value, alongside the proposed millage rates of each taxing authority and the dates of their public budget hearings. Comparing this year's just value to last year's tells you how much the appraiser raised you.

Why the deadline lives here. Section 200.069 requires the notice to state that “you may file a petition for adjustment with the Value Adjustment Board” and that petition forms “must be filed ON OR BEFORE” a printed date. That printed date is the 25th day after the notice is mailed under Fla. Stat. §194.011(3)(d). Miss it and you generally lose the VAB route for the year.

What to do when it arrives. (1) Read the date printed next to the VAB instructions — calendar it immediately. (2) Check whether your homestead, Save Our Homes cap, and other exemptions are correctly applied; an exemption error is often easier to win than a value dispute. (3) If only the value looks wrong, call your county property appraiser to request an informal conference first, then file a Form DR-486 petition before the printed deadline if you are not satisfied.

Keep the notice — the values printed on it are the figures you are contesting, and the VAB clerk will reference them.
