Every Florida homeowner dreads August âÃÂànot because of the heat, but because of the envelope that arrives from their county property appraiser. The TRIM notice (Truth in Millage) is your annual property assessment notice, and the number printed on it determines how much you'll pay in property taxes for the coming year. In 2026, TRIM notices will begin arriving in mid-August, and once yours lands in your mailbox, the clock starts ticking on a strict 25-day deadline to file an appeal. Here's exactly when to expect your notice and what to do when it arrives.
What Is a TRIM Notice and Why Does It Matter?
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 âÃÂàit'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.
2026 TRIM Notice Mailing Dates by County
Florida law requires TRIM notices to be mailed by August 24 each year, but most counties mail earlier. Here's when to expect yours in 2026 based on historical patterns:
- ✓Miami-Dade County âÃÂàtypically mails around August 15-17
- ✓Broward County âÃÂàtypically mails around August 15-18

Your 25-Day Deadline: The Most Important Date of the Year
From the date your TRIM notice is mailed âÃÂànot the date you receive it âÃÂàyou have exactly 25 days to file a Value Adjustment Board (VAB) petition challenging your assessment. In 2026, this means most Florida homeowners will face 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.

Do I need my TRIM notice in hand to file an appeal? ▾
No. TaxAppeal USA can file your VAB petition before your TRIM notice even arrives, using your property's current assessed value from county records. This gives you maximum time buffer before the deadline.
