Auditor’s Office Wins National Award for Audit of Property Tax Exemptions

The Association of Local Government Auditors’ Awards Program Committee announced that the King County Auditor’s Office’s report, “Property Tax Exemptions: Stronger Systems Needed to Meet Demand,” won the 2022 Distinguished Knighton Award in the large shop category, calling it one of the best reports of 2022. They noted that it was a relevant subject that could have significant impact on some of the most vulnerable residents of the community. They said the King County Auditor’s Office made specific, feasible, and actionable recommendations for improvement and the effective use and placement of visuals conveyed the message and enhanced the report’s readability. Rather than simply narrating a story, the auditor effectively used charts and graphs to demonstrate changes in workloads and backlogs to correlate the impacts on wait times for property tax exemption approvals.
