Hillsborough County's 2026 property tax appeal deadline is set by notice, not by a fixed calendar date.
Hillsborough County publishes the rule rather than a 2026 calendar date. Its Value Adjustment Board filing instructions state the deadline is on or before the 25th day following the date the Property Appraiser mails the TRIM notice, and direct owners to the date printed on their own notice. The Property Appraiser confirms 2026 TRIM notices began mailing August 13, 2026.
What starts the clock: TRIM notices began mailing August 13, 2026, per the Hillsborough County Property Appraiser's press release dated August 7, 2026

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.
