1. Choose a Business Name

In North Dakota, a sole proprietor may use his or her own given name or may use a trade name.  If you plan to us an assumed name or trade name, state law requires that the name be distinguishable from the name of another company currently on record. It is also a good idea to choose a name that is not too similar to another registered business because of common and federal law trademark protections. To make sure your business name is available, run a search in the following government databases:

 2. File a Trade Name

If you use a business name that is different from your legal name, North Dakota requires you to register a trade name with the Secretary of State. This is a mandatory requirement in North Dakota. To file your trade business name, you must fill out a Trade Name Registration and mail it to the Secretary of State at the address listed in the application.  The filing fee is $25.

 3. Obtain Licenses, Permits, and Zoning Clearance

Your business may need to obtain business licenses or professional licenses depending on its business activities.  North Dakota provides a comprehensive website of every profession and occupation that requires a license by any sole proprietorship. A business can obtain this information by going to North Dakota's Boards and Commissions. In addition, local regulations, including licenses, building permits, and zoning clearances, may apply to your business. You will need to check with your city and county governments for more information.

4. Obtain an Employer Identification Number

Sole proprietors who wish to have employees need to obtain an Employer Identification Number, or EIN.  This is a nine-digit number issued by the IRS to keep track of businesses.  All businesses with employees are required to report wages to the IRS using their EIN. Registering for an EIN can be done online at the IRS website.

Even if you don’t have employees, you may want to obtain an EIN. Some banks require one to open a bank account and it can reduce the risk of identity theft.

In North Dakota, businesses are required to report taxes and file various employee reports. You may need to use your EIN when registering your business to report taxes through the North Dakota New Business Registration. If you have employees, you must report and pay employment taxes on a periodic basis.  More information related to employment taxes can be obtained by registering with the North Dakota New Business Registration.

Next Steps

It is important to consider doing the following once you have established your sole proprietorship:

  • Open a business bank account. Using your fictitious business name and EIN, you should set up a bank account to keep your business and personal finances separate.
  • Obtain general liability insurance. Because sole proprietors are personally liable for all debts and obligations of the business, a business liability insurance policy may be the only form of financial protection against unforeseen events.
  • Report and pay taxes.  Depending on your specific business activities, you may be required to report such items as sales tax and use tax. You can obtain more information by registering with the North Dakota Webfile.
