What Is TRIM Notice?

Truth in Millage notice — a document sent to Florida property owners each August showing proposed property taxes, which triggers the appeal window.

Detailed Explanation

The TRIM (Truth in Millage) notice is Florida's version of the property assessment notice. It is mailed to every property owner in August each year and shows both the county property appraiser's estimate of your property's value and the proposed tax rates from each taxing authority (county, city, school district, special districts). The TRIM notice is your signal to act. Once you receive it, you have 25 days to file an appeal with the Value Adjustment Board (VAB) if you believe your property's assessed value is too high. The TRIM notice contains several key pieces of information: your property's "just value" (market value), the assessed value (which may differ if you have homestead exemption with the Save Our Homes cap), all applicable exemptions, the proposed millage rate from each taxing authority, and your estimated tax bill for the upcoming year. Comparing this year's notice to last year's is the quickest way to spot a significant increase that may warrant an appeal. One important Florida-specific detail: the "assessed value" on your TRIM notice may be lower than the "just value" if you have a homestead exemption. Florida's Save Our Homes amendment caps annual increases on homesteaded property assessments at 3% or the Consumer Price Index, whichever is lower. This creates a gap between your home's market value and its capped assessed value that grows over time.

Common Misconceptions

Myth:The TRIM notice is my final tax bill

Reality:The TRIM notice shows proposed taxes based on tentative millage rates. Final rates are set by each taxing authority at public hearings in September. Your actual bill may be slightly different.

Myth:If I have a homestead exemption, I cannot be overassessed

Reality:The homestead exemption and Save Our Homes cap apply to your assessed value, but your just value (market value) can still be wrong. You can appeal the just value even with a homestead exemption.

Myth:I can only appeal the property value, not the tax rate

Reality:That is actually correct for the VAB process. The millage rate is set through the budget process at public hearings. Your VAB appeal targets the property value and exemptions only.

Impact on Your Tax Bill

In Palm Beach County, Florida, if your TRIM notice shows a just value of $550,000 but comparable sales show $490,000, the $60,000 difference matters. At a total millage of about 19 mills, that overassessment costs you $60,000 / 1,000 x 19 = $1,140 per year.
