Some Bay Area counties have automatically cut property tax assessments for 2023-24 on homes that sold near the recent peak in home prices. Owners who think their homes are worth less than their assessed value can ask their county assessor for an informal review or file a formal appeal with their county Assessment Appeals Board. Check this chart for the deadlines and fees by county.
