Minnesota Sales Tax Audit Readiness Checklist
Introduction
Minnesota sales tax is a tax on retail purchases of goods and certain services. If your business collects or owes sales tax, the Minnesota Department of Revenue may conduct an audit to verify you have reported and paid the correct amount. An audit is a formal examination of your records, receipts, and tax filings to ensure compliance with state law. Understanding what an audit involves and how to prepare helps you respond appropriately and reduces stress during the process. Audits are a routine part of state tax administration and do not automatically indicate wrongdoing.
What This Issue Means
A sales tax audit is a formal review by the Minnesota Department of Revenue of your business's sales tax records, filings, and payments. The state examines whether you correctly identified taxable sales, applied the right tax rates, collected tax from customers, and remitted payment on time. An audit notice is a written request from the state asking you to provide specific documents and records within a set timeframe. This does not mean you have committed fraud or broken the law.
Why the State Issued This or Requires This
Minnesota conducts sales tax audits for several administrative reasons. The state may randomly select a business for a routine compliance review. The state may also initiate an audit if sales tax filings show unusual patterns, missing returns, or incomplete payment history. If a customer files a complaint or if the state identifies inconsistencies between reported income and reported sales tax, an audit may follow. The specific trigger for your audit is typically stated in the audit notice itself.
What Happens If This Is Ignored
Failing to respond to an audit notice or to do so by the deadline typically results in escalated enforcement action. The Minnesota Department of Revenue may proceed with the audit using only the information available to them, which may result in estimated tax assessments against your business. If you do not respond, the state may issue a notice of assessment that imposes additional taxes, penalties, and interest. The state may then pursue enforcement actions through wage levies, bank levies, or other collection tools if the debt remains unpaid.

Look at each sales tax return filed during the audit period. Check that reported sales figures match your sales records and accounting records, and verify that taxable sales were correctly identified.
