How to appeal your Miami-Dade County property taxes

  1. Check first (free). Enter your address — we compare the county's assessed value to an independent market estimate from official Miami-Dade County sales.
  2. Watch your TRIM notice. Miami-Dade County mails proposed values in mid-to-late August. That starts a strict 25-day clock.
  3. File Form DR-486 with the Miami-Dade County Value Adjustment Board — $15, online. We assemble the completed petition and comparable-sales evidence so you're ready.
  4. You sign and file. We're your tool, not your representative — you stay in control, and you keep 100% of your savings (flat fee, never a percentage).
