How to Form a Sole Proprietorship in North Dakota

Quick Answer

Forming a sole proprietorship in North Dakota is the simplest business structure available, requiring no formal state filing or registration fees. As of April 13, 2026, you can start operating immediately once you obtain any required business licenses and register for tax purposes. The main requirements are obtaining an EIN from the IRS (if you have employees) and registering with North Dakota Tax Commissioner for state tax obligations.

Step-by-Step Formation Process

Unlike corporations or LLCs, sole proprietorships in North Dakota don’t require formal state registration. Here’s how to establish your sole proprietorship:

1. Choose Your Business Name: You can operate under your legal name or file a “Doing Business As” (DBA) certificate with your county clerk if you want to use a different business name.

2. Check Name Availability: If using a DBA, search the North Dakota Secretary of State’s business name database to ensure your chosen name isn’t already in use.

3. File DBA Certificate (if applicable): Submit your DBA certificate to the county clerk in the county where your business is located. Contact your local county clerk’s office for current filing procedures and fees.

4. Obtain Required Licenses and Permits: Research and apply for any business licenses or permits required for your specific industry through the North Dakota Secretary of State’s licensing portal.

5. Get an Employer Identification Number (EIN): Apply for an EIN through the IRS website if you plan to hire employees or want to separate your business and personal finances. This is free when done directly through the IRS.

6. Register for State Taxes: Contact the North Dakota Tax Commissioner’s office to register for state income tax withholding and sales tax collection if applicable to your business type.

7. Open a Business Bank Account: While not legally required, opening a separate business bank account helps maintain clear financial records for tax purposes.

Costs Breakdown

As of April 13, 2026, here are the typical costs associated with forming a sole proprietorship in North Dakota:

Item	Cost	Notes
State Formation Fee	$0	No state filing required
DBA Filing (County)	Varies by county	Contact local county clerk for current fees
EIN from IRS	Free	Apply directly through IRS.gov

The minimal cost structure makes sole proprietorships the most affordable business entity option in North Dakota. Most costs will come from industry-specific licensing requirements rather than entity formation fees.

Requirements Checklist

Before starting your sole proprietorship in North Dakota, ensure you have:

• Valid Social Security Number or Individual Taxpayer Identification Number
• Business name decision (your legal name or chosen DBA)
• DBA certificate filed with county clerk (if using business name other than your legal name)
• Research completed on required business licenses and permits
• EIN obtained from IRS (if hiring employees or preferred for banking)
• State tax registration completed with North Dakota Tax Commissioner
• Business bank account opened (recommended but not required)
• Business insurance researched and obtained as needed

Tax Implications

As of April 13, 2026, North Dakota sole proprietors face the following tax obligations:

State Income Tax: North Dakota imposes individual income tax at rates ranging from 1.1% to 2.9% on business profits. As a sole proprietor, you’ll report business income and expenses on your personal state tax return.

Federal Self-Employment Tax: You’ll owe 15.3% self-employment tax on net business earnings over $400, covering Social Security and Medicare contributions.

Sales Tax: North Dakota’s base sales tax rate is 5.0%. If your business sells taxable goods or services, you must collect and remit sales tax to the state. Register with the North Dakota Tax Commissioner’s office for a sales tax permit.

No Franchise Tax: North Dakota does not impose franchise taxes on sole proprietorships, unlike some other business entities.

Quarterly Estimated Taxes: If you expect to owe $1,000 or more in federal taxes, you must make quarterly estimated tax payments to both the IRS and North Dakota Tax Commissioner.

Ongoing Obligations

Sole proprietorships in North Dakota have minimal ongoing compliance requirements:

Annual Tax Filings: File federal Schedule C with your personal tax return and North Dakota individual income tax return by April 15th (or the extended deadline if you file an extension).

Sales Tax Returns: If registered for sales tax, file monthly, quarterly, or annual returns as assigned by the North Dakota Tax Commissioner.

Business License Renewals: Renew any required business licenses according to their specific renewal schedules.

Record Keeping: Maintain detailed business records for at least three years, including income, expenses, receipts, and bank statements for tax purposes.

Employment Tax Obligations: If you hire employees, you’ll need to file quarterly employment tax returns and annual forms with both federal and state authorities.

Registered Agent

Sole proprietorships in North Dakota do not require registered agents. This requirement only applies to corporations and limited liability companies. As a sole proprietor, you’ll receive legal documents and official correspondence directly at your business address or personal address.

However, if you later decide to convert your sole proprietorship to an LLC or corporation, you’ll need to designate a registered agent who maintains a North Dakota address and is available during business hours to receive legal documents.

Common Mistakes to Avoid

1. Mixing Personal and Business Finances: Even though it’s not legally required, failing to separate business and personal expenses makes tax preparation difficult and may trigger IRS scrutiny.

2. Ignoring Local Licensing Requirements: Many sole proprietors assume they don’t need business licenses, but requirements vary by industry and municipality. Research thoroughly before starting operations.

3. Failing to Register for Sales Tax: If your business sells taxable goods or services, you must register with the North Dakota Tax Commissioner. Operating without proper registration can result in penalties.

4. Not Making Quarterly Estimated Tax Payments: Unlike employees who have taxes withheld, sole proprietors must proactively pay estimated taxes quarterly to avoid penalties.

5. Using Personal Name When Business Name is Required: Some industries or contracts require a formal business name. File a DBA certificate when necessary to operate legally.

6. Inadequate Record Keeping: Poor financial records make tax filing difficult and may result in missed deductions or IRS problems during audits.

7. Assuming No Insurance is Needed: While not legally required for formation, general liability insurance protects your personal assets since sole proprietorships offer no liability protection.

FAQ

Can I form a sole proprietorship online in North Dakota?

Do I need a business license to operate a sole proprietorship in North Dakota?

Business license requirements depend on your specific industry and location, not your business entity type. Many sole proprietorships need licenses or permits to operate legally. Check with the North Dakota Secretary of State’s licensing division and your local municipality to determine what licenses your business requires.

How is a sole proprietorship taxed differently from an LLC in North Dakota?

Both sole proprietorships and single-member LLCs are taxed similarly in North Dakota - business income passes through to your personal tax return.

What’s the difference between a sole proprietorship and a DBA in North Dakota?

A sole proprietorship is a business entity type, while a DBA (Doing Business As) is simply a way to operate under a business name other than your legal name. You can have a sole proprietorship without a DBA if you operate under your personal name, or you can file a DBA to use a business name.

Do I need liability insurance for my North Dakota sole proprietorship?

General liability insurance provides crucial protection for most business operations.

How do I close a sole proprietorship in North Dakota?

Closing a sole proprietorship in North Dakota is straightforward since there’s no state registration to cancel. Simply stop business operations, file final tax returns, cancel any business licenses, close business bank accounts, and notify customers and vendors. If you filed a DBA, you may want to file a cancellation with the county clerk.

Can I convert my sole proprietorship to an LLC later?
