Deadline and where to file
Mansfield values are set by the local county assessor. File your petition with the County Board of Equalization by July 1 of the assessment year, or within 30 days after the assessor mailed your change of value notice, whichever is later. Counties can extend the 30 days to up to 60 days, so check your county.
Reading this in fall 2026? The 2026 deadline has passed (July 1, 2026, or 30 to 60 days after your notice, depending on the county). Your next chance is the 2027 assessment: notices are mailed during 2027 and you can file by July 1, 2027, or 30 days (60 in counties that extended) after your notice date, whichever is later. If you already appealed in 2026, the Board of Tax Appeals deadline is 30 days from the date the county board mailed its decision.
