Who must register for Minnesota sales tax
You must register for a Minnesota Tax ID number if your business has a sales tax nexus in the state. This usually applies when a business:
- Exceeds the economic nexus threshold of $100,000 in annual sales or 200 or more separate transactions into Minnesota in the current or previous calendar year, or;
- Has a physical presence in Minnesota, such as an office, employee, warehouse, or inventory stored in the state.
Minnesota's dual threshold means you must register once you cross either the dollar amount or the transaction count, whichever comes first.
Once you exceed the threshold, you should register before making further taxable sales in Minnesota. If you're unsure whether your business has nexus, see the Minnesota Sales Tax Guide for a broader explanation.
How to register for Minnesota sales tax
Sellers can register online through Minnesota e-Services, the state's centralized tax portal. This is the same portal you will use to file returns and make payments after registration.
Information you need before registering
Before applying for a Minnesota Tax ID number, have this information ready:
- Your Social Security number (if registering as a sole proprietor with no employees)
- Your Employer Identification Number (EIN), if your business has one (required for corporations, partnerships, and most LLCs)
- North American Industry Classification System (NAICS) code for your primary business activity

What happens after registration
After registering, you must begin collecting Minnesota sales tax on taxable sales and file returns based on your assigned filing frequency. Returns are generally due on the 20th of the month following the reporting period.
Minnesota taxes digital goods and SaaS, which is an important consideration for software businesses. Local city and county taxes in Minnesota are filed on the same state return. No separate local filings are required. See the Minnesota Sales Tax Guide for details on taxability.
