Important note: Zero returns
Once you have a Michigan Sales Tax License, you are required to file returns for every assigned period regardless of whether any sales tax was collected. When no sales tax was collected, you must file a zero return electronically through Michigan Treasury Online.
How to prepare your Michigan sales tax return
Before working on your sales tax return, collect all sales information for the tax period.
Sales transactions
You need to know your total gross sales to Michigan buyers and your taxable sales. Michigan taxes digital goods and SaaS, so online businesses selling software or digital products into Michigan must include those sales in their taxable total.
Key reporting figures
In addition to your gross Michigan sales, filing a return requires:
- Total sales and income
- Taxable sales
- Non-taxable sales and exemptions
- Deductions and adjustments
- Total sales tax collected from customers during the filing period
Because Michigan has no local sales taxes, you apply a single flat 6% rate to all taxable sales statewide, which simplifies reporting compared to states with county-level rates.
How to complete and file a Michigan sales tax return
Michigan sales tax returns are filed electronically through Michigan Treasury Online (MTO) and must be reported in US dollars.
Step-by-step: file a Michigan sales tax return
1. Collect all necessary information
Gather your sales records for the tax period. Because Michigan has no local sales taxes, you only need to track total Michigan sales and identify which are taxable under state law.
2. Log in and file online
- Log in to Michigan Treasury Online (MTO).
- Navigate to your Sales Tax account.
- Select the filing period you want to file.
- Enter your gross sales, taxable sales, exemptions, and total tax collected.

3. Receive confirmation
After submitting, you will receive a confirmation number. Save this as your record of filing.
How to pay sales tax in Michigan
Michigan requires businesses to file and pay electronically through Michigan Treasury Online. You can pay directly within the portal after filing your return. Accepted payment methods include:

Late filing penalties and interest
If you miss a Michigan sales tax filing deadline, file as soon as possible. Failure to file returns and remit collected tax on time results in penalties and interest charges that increase the longer you wait.
For current penalty rates and interest charges, refer to the Michigan Department of Treasury website.
