Why do I have two supplemental tax bills?

State law requires the Assessor to reappraise property upon change in ownership or completion of new construction. The supplemental assessment reflects the difference between the new value and the old value.  If the change in ownership or completion of construction occurs between January 1 and May 31, there will be two supplemental tax bills.

The first supplemental is for the remainder of the fiscal year and the second bill is for the fiscal year that follows.
