What is the “Supplemental Roll?
The “Supplemental Roll” is the accumulation of supplemental assessments made by the Assessor. The property is first reassessed by staff of the Assessor’s office. The reassessments are then sent to the County Auditor for enrollment. After that, they go to the Tax Collector for the creation and mailing of supplemental bills. Due to the large volume of reassessments, staffing considerations and other factors, the whole process may take several weeks to several months between the supplemental event and the mailing of tax bills.
