In this guide
For many Florida homesteaders, though, a market-value appeal changes nothing on the bill. Whether an appeal helps you depends on one number, and this guide shows you how to read it.
The Save Our Homes trap (read this first)
Florida keeps two values for every homestead: the just value (the market estimate) and the assessed value (just value minus the accumulated Save Our Homes cap, which limits assessed increases to 3% or the change in CPI, whichever is lower). Your tax bill runs on the assessed value, not the just value.
If you've owned your home for years, your assessed value can sit far below your just value. In that case, even a successful appeal that lowers your just value won't touch your bill — unless the reduction drops just value below your already-capped assessed value. This is why comparing your tax bill to a neighbor's is the wrong metric: two identical homes carry different bills legitimately, based on when each owner bought.
Who an appeal actually helps
- Recent buyers — when you buy, the Save Our Homes cap resets to market, so a new owner's assessed value equals just value. A lower just value then lowers the assessed value the bill runs on, and the base later capped increases start from.
- Non-homestead and investment properties — capped at 10%, the differential is usually small, so an appeal can move the bill.
- Homes with condition issues — damage or deferred maintenance can support an appeal on evidence beyond comparable sales.
Filing in Miami-Dade County: the steps and the deadline
You file Form DR-486 with the Clerk of the Value Adjustment Board — not with the Property Appraiser. The deadline is 25 days from the TRIM mailing date printed on your notice, which typically lands in late August and puts the deadline in September. A $15 filing fee applies, and several counties require the petition be received by the deadline — a postmark is not enough.
You can also request an informal review with the appraiser's office first. If you do go to a hearing, it's before a special magistrate, and the evidence is comparable sales — similar homes with lower just values or recent sales below your assessed figure.
The bottom line
An appeal changes the bill only when it lowers the value the bill runs on. For a long-tenured homesteader whose assessed value sits well below just value, a market-value appeal may change nothing; for a recent buyer or a non-homestead property, it can. Confirming every exemption you qualify for is on the roll is a separate check. PaxGuard reads your county's live roll to show which case you're in, and only builds appeal evidence when the numbers support one.
Questions
Questions homeowners ask
What is the deadline to appeal property taxes in Miami-Dade County?
25 days from the date your TRIM notice is mailed — typically late August, putting the deadline in September. The exact date is printed on your notice, and several counties require the petition be received (not postmarked) by then.
Will appealing my property taxes lower my bill?
Only if it lowers the value your bill actually runs on. Florida bills run on assessed value (just value minus the Save Our Homes cap). For long-tenured homesteaders with a large cap, a market-value appeal often changes nothing; for recent buyers, whose assessed value equals just value, a lower just value lowers the assessed value too.
Do I file the appeal with the Property Appraiser?
No — you file Form DR-486 with the Clerk of the Value Adjustment Board. You can meet informally with the appraiser's office first, but the petition itself goes to the VAB clerk.
Does PaxGuard file the appeal for me?
No. PaxGuard prepares the evidence and a DR-486 data sheet; you review and file it yourself as the taxpayer of record. It is not legal or tax advice.
