Where to file and who enforces the decision

The County Assessor supplies the assessed value and background information, while the Treasurer and Tax Collector handles tax billing and any penalties or interest on unpaid taxes. Contact the Assessment Appeals Board to obtain the official appeal application and current filing instructions.[1][2][3]

Penalties & Enforcement
