State law requires the Assessor to reappraise property upon a change of ownership or new construction. The supplemental assessment reflects the difference between the new assessed value and the old or prior assessed value. If the property is reassessed at a higher value than the old assessed value, a supplemental bill will be issued by the Tax Collector. If the property is reassessed at a lower value than the old assessed value, a refund will be issued. Changes in ownership or new construction occurring from July 1 to Dec 31 will generate one bill covering a single fiscal year. The taxes are based on the number of months left in the fiscal year from the date of ownership change or the new construction completion date. If the change of ownership or new construction occurs between January 1 and June 30, two supplemental tax bills would be issued to cover changes for two fiscal years. The first bill would be from the date of the transaction for the remainder of the fiscal year; the second bill would be for the next fiscal year. Supplemental tax bills are mailed directly to the property owner and are the owner’s responsibility. In general, they are not paid out of your impound account. Please check with your lender.
