Contest a Sales Tax Audit in Detroit, Michigan
Retailers operating in Detroit, Michigan must respond promptly when notified of a sales or use tax audit by the state or when local licensing reviews affect sales activity. Most sales tax enforcement for in-store and online retail is administered by the Michigan Department of Treasury, while Detroit departments may review business licenses and local compliance. This guide explains how to challenge audit findings, preserve records, pursue appeals, and use available administrative and tribunal processes so Detroit businesses can limit penalties and avoid escalation.
What triggers a sales tax audit
Audits commonly arise from mismatches in reported sales, large refund claims, third-party information, point-of-sale errors, or a change in business operations such as adding taxable services. Prepare to show books, POS reports, exemption certificates, and contracts.
Preparing to contest the audit
- Gather records: sales journals, POS tapes, exemption certificates, resale certificates, invoices, and bank deposits for the audit period.
- Review the audit notice for scope, period, and contact person; request clarification in writing if unclear.
- Meet deadlines for producing documents or scheduling meetings; ask for a realistic extension in writing if needed.
- Consider hiring a tax professional or attorney experienced with Michigan sales and use tax audits.
