Williamson County homeowners are encouraged to protest their property tax assessment, regardless of whether it was increased, reduced, or remained flat. Williamson Appraisal District has limited staff to value well over 200,000 homes in Williamson County. Homes are valued using the cost approach. The only option for quality control is a property tax protest. Otherwise, Williamson Appraisal District staff is highly unlikely to review the estimate of value generated by their computers.

There is no risk to appealing. The appraisal district and appraisal review board may not increase the assessed value due to an appeal. The only options are to reduce it or leave it the same. 85% of homeowners who appealed in 2019 were successful in reducing their property tax assessment.

The property tax appeal deadline is Monday, May 17th.
