The 2026 deadline is September 11, 2026. The Pinellas County Property Appraiser's dates calendar states TRIM notices mail August 17, 2026 and lists September 11, 2026 as the deadline to file a Value Adjustment Board petition, consistent with the 25 day statutory window.
Appeals are filed with the Value Adjustment Board, c/o Board Records Department, Clerk of the Circuit Court and Comptroller, 315 Court Street, 5th Floor, Clearwater, FL 33756, or online. The governing jurisdiction is the Pinellas County Value Adjustment Board.
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.
