What is a Supplemental Assessment?
State law requires the Assessor's Office to reappraise property upon change in ownership or completion of new construction. The Assessor's Office must issue a supplemental assessment which reflects the difference between the prior assessed value and the new assessment. This difference in value is prorated based on the number of months remaining in the fiscal year, ending June 30. (Generally, Supplemental Assessments are not accounted for in escrow dealings, but the new property owner should be made aware of the supplemental process.)
This is in addition to the regular tax bill. Notices of the supplemental assessment(s) are mailed out to property owners prior to the issuance of the tax bill. The owner has the right to file an application for appeal within 60 days of the date of notice. Because of legal and workload ramifications, it normally takes several months to generate a supplemental tax bill. If you acquire a piece of real estate, or add real property improvements after January 1 and prior to May 31, you will receive two (2) bills.
