Michigan sales tax debt: how Treasury collects and what you can do

The Michigan Department of Treasury administers sales, use and withholding tax (often filed together as "SUW"). Michigan has a single statewide rate of 6% and no local sales taxes, which makes Michigan balances simpler to reconstruct than in states with hundreds of local rates. Filing frequency (monthly, quarterly or annual) is assigned by Treasury based on your liability, and every period must be filed even if no tax is due.

Treasury charges penalty and interest on tax paid after the due date and on tax that was never remitted. Unfiled periods are typically estimated by Treasury and billed, and estimated assessments are frequently higher than what the business actually owes — filing the real returns is usually the fastest way to bring a bill down.

We haven't found an official Treasury page that states the current sales-tax penalty schedule in a form we can quote reliably, so check the penalty shown on your notice or call Treasury rather than relying on a number from a third-party site.

According to Treasury's collections guidance, a business that owes a state debt and can't pay in full may qualify for monthly payments. While an agreement is in place:

• Penalties and interest continue to accrue until the balance is paid.
• Treasury may file a tax lien to protect the state's interest.
• State refunds are redirected to the collections account.
• New debts or missed payments can cancel the plan and restart collection.

Treasury asks for financial information to set the payment, so have recent bank statements and a realistic monthly figure ready. Staying current on new SUW returns is effectively a condition of keeping the plan.

Michigan's Revenue Act lets Treasury hold responsible officers, members and managers personally liable for unpaid sales, use and withholding taxes of a business — the state equivalent of the federal Trust Fund Recovery Penalty. Because sales tax is collected from customers, Treasury treats unremitted tax similarly to withheld payroll tax. An LLC or corporation does not by itself shield the person who decided which bills got paid.

If you disagree with a Michigan assessment, you can request an informal conference with Treasury's Hearings Division before the deadline printed on the notice, and further appeals go to the Michigan Tax Tribunal or Court of Claims. Deadlines are short and printed on each notice — don't wait for a second letter.

Practical order of operations: file every missing return, pay the current period on time, then request an installment agreement for the older balance. The free business tax relief assessment shows which routes may fit before you call.
