SUPPLEMENTAL PROPERTY TAXES 47. What are “supplemental” property taxes?
“Supplemental” taxes are additional secured taxes that are due when property undergoes a change in ownership or new construction. The additional tax is owed because the County Assessor is required to immediately adjust the January 1 value to reflect the new value of the property. Adjusted for the number of months left in the fiscal year, the supplemental tax bill represents the tax due on the difference between the old and new values.
