The 2026 deadline to appeal a Polk County property tax assessment is September 11, 2026. The filing window runs from January 1, 2026 to September 11, 2026.
For Florida valuation issues, a VAB petition may be filed at any time during the taxable year on or before the 25th day following mailing of the assessment notice/TRIM notice. Polk County Clerk's official VAB page prints the 2026 county petition filing deadline as September 11, 2026 at 5:00 pm. Because the statute says filing may be made at any time during the taxable year, the filing window starts January 1, 2026 for 2026 taxable-year valuation petitions.

Appeals are filed with the Polk County Value Adjustment Board / Clerk of the Value Adjustment Board. The governing jurisdiction is the Polk 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.
