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
How It Varies by State
25-day appeal window after mailing. File petition with county Value Adjustment Board (VAB). Filing fee ranges from $15 to a few hundred depending on value.
Similar purpose but different name and timeline. Protest deadline is May 15 or 30 days after notice, whichever is later.
Mailed when values change. 45-day appeal window. Filed with county Board of Tax Assessors.
Published by each municipality. Grievance Day is typically third Tuesday in May.
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.
