Inaccuracies in mapping software used by the state to determine local tax rates are causing undue headaches for taxpayers across the state, according to a new report from Missouri Auditor Nicole Galloway.
The audit looked at sales and use tax collections processes used by the Missouri Department of Revenue after Missourians purchase motor vehicles. According to the report, the mapping software used to determine tax rates is often inaccurate in 15 counties, forcing residents to provide additional identification if they hope to avoid paying incorrect tax rates.
The report also recommended amending state laws for handling refunds of sales tax overpayments.
Despite the issues, the report — which covered fiscal years 2015 to 2017 — lists the overall performance of the department’s sales and use tax as “good.”
