What is a secured property supplemental tax bill?
A supplemental assessment is an adjustment in real property valuation resulting from upward changes in assessed value due to changes in ownership or completion of new construction. A secured property supplemental tax bill retroactively taxes the supplemental assessment of property on a pro- rata basis as a result of the assessor’s reappraisal of property at its full cash value on the date that a change in ownership occurs or new construction is completed.
