The 2026 deadline is September 14, 2026. The window opens January 1, 2026. The Palm Beach County Property Appraiser states the 2026 petition filing deadline is September 14, 2026. Florida law sets the deadline on or before the 25th day following the mailing of the TRIM notice.
Appeals are filed with the Palm Beach County Value Adjustment Board, petitions filed via myVAB or with the Clerk of the Circuit Court & Comptroller, 301 N. Olive Avenue, Room 206, West Palm Beach, FL 33401. The governing jurisdiction is the Palm Beach County.
Florida counties mail a TRIM notice (Truth in Millage) in August, and a petition to the county Value Adjustment Board is due 25 days after the notice is mailed. Petitions are typically heard by a special magistrate, and many resolve on the evidence or in an informal conference with the property appraiser first. Non-homestead assessments can rise up to 10% a year, so a value that starts high keeps compounding — a reduction applies to that tax year, which is why it is worth filing in every year the assessment is wrong.
It can happen — in Florida the property appraiser may revise a value upward where a factual error in the physical record is discovered during the appeal (Fla. Admin. Code R. 12D-9.025(6)(c)). That's why we check for that exposure before filing: we don't file when we see it, and if it surfaces after filing we withdraw.
