Florida TRIM notices arrive in August. Find out the exact mailing dates by county, your 25-day deadline to appeal, and what to do the moment your notice arrives.
TRIM stands for Truth in Millage. Florida law requires every county property appraiser to mail this notice each August, showing your proposed assessed value, applicable exemptions, and the estimated taxes you'll owe based on proposed millage rates from local taxing authorities. The TRIM notice is not your tax bill — it's your proposed assessment. But it determines your tax bill, which is why it matters enormously. If your assessed value is inflated, your taxes will be inflated. The TRIM notice is your one annual opportunity to challenge that number.
Florida law requires TRIM notices to be mailed by August 24 each year, but most counties mail earlier. Here's when to expect yours based on historical patterns:
From the date your TRIM notice is mailed — not the date you receive it — you have exactly 25 days to file a Value Adjustment Board (VAB) petition challenging your assessment. In 2026, this meant most Florida homeowners faced a petition deadline between September 9 and September 18. Missing this deadline means waiting a full year to challenge your assessment and paying inflated taxes in the meantime. Florida law is unambiguous on this point: there are no extensions and no exceptions.
When your TRIM notice arrives, do three things immediately. First, note the mailing date printed on the notice — this starts your 25-day countdown. Second, check your assessed value against what you believe your home is worth in the current market. Third, if your assessed value seems high, start the appeal process immediately — don't wait until the last week. TaxAppeal USA emails your ready-to-sign VAB petition as a PDF the day you order, and mails you the printed kit.
TaxAppeal USA is built specifically for Florida's TRIM season. First we check the county roll to see whether a reduction would reach your bill at all — and if the Save Our Homes cap would absorb it, we say so instead of selling you a petition. If it would, we prepare Form DR-486 with comparable values and mail you a ready-to-sign kit with a return envelope addressed to your county's Value Adjustment Board; a PDF copy of the full kit is also emailed to you the same day. You sign it, add a cheque for the county's filing fee, and mail it the day it arrives. It costs a flat $89.
We check first. If an appeal will lower your bill, we mail you a ready-to-sign kit for $89 flat. You sign it and mail it, and you keep 100% of your savings.
TaxAppeal USA is a self-service document-preparation service. We prepare a ready-to-sign appeal kit and mail it to you; you sign it and mail it to the county yourself. In every state we serve, including Florida, we are not property tax consultants, agents, or representatives, we do not provide tax or legal advice, and we do not file appeals or represent customers before any appraisal district, board of assessors, board of equalization, value adjustment board, or review board. Every appeal, protest and petition is prepared for the property owner, signed by the owner, and mailed by the owner in the owner’s name. In Florida your petition is signed by you as the property owner under section 194.011(3), Florida Statutes, and the county’s Value Adjustment Board filing fee is paid by you directly to the county. TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
