Key Dates for San Bernardino County
| Appeal deadline | Regular (decline-in-value) assessment appeals are filed July 2 through November 30 of each year with the Clerk of the Board of Supervisors. San Bernardino County uses the November 30 close because the Assessor does not mail an annual notice of assessed value to all assessees by August 1 (the July 2 - September 15 window applies only to counties that issue such notices by August 1). Supplemental, escape, and roll-change/calamity assessments must be appealed within 60 days of the mailing/postmark date of the notice or tax bill. A $45.00 non-refundable administrative processing fee must accompany each application. |
