Sole Proprietorship in North Carolina: How to Start One

A sole proprietorship is the default business structure in North Carolina. If you start doing business as an individual and never file anything to become an LLC or corporation, you are already a sole proprietor under state law. That makes it the fastest and cheapest way to start a business in North Carolina, but "fast and cheap" comes with a tradeoff: there is no legal separation between you and the business. Your personal assets are on the hook for business debts and lawsuits.

This guide walks through exactly what a North Carolina sole proprietorship requires, step by step, including the one filing most people forget: the Assumed Business Name Certificate. It's informational content, not legal or tax advice. For anything beyond a simple, low-risk operation, talk to a North Carolina attorney or CPA before you commit to a structure.

What a Sole Proprietorship Actually Is

There's no formation document for a sole proprietorship, and nothing gets filed with the North Carolina Secretary of State to create one. You, the individual, and the business are the same legal entity. You report business income and expenses on your personal tax return (Schedule C on your federal return, then flowing into your North Carolina return), and you're personally liable for anything the business owes.

Compare that to an LLC, where North Carolina requires Articles of Organization (Form L-01, a $125 filing fee) with the Secretary of State, plus a $200 annual report every year after. A sole proprietor in North Carolina skips both. That's the appeal, and it's also the risk: without the LLC's liability shield, a business debt or a lawsuit against the business can reach your personal bank account, car, or home equity.

Materials and Information You'll Need

  • A business name, either your own legal name or a trade name (also called a "doing business as" or DBA name)
  • Your Social Security number, or an Employer Identification Number (EIN) from the IRS if you'd rather not use your SSN on business paperwork
  • An Assumed Business Name Certificate, only if you're operating under a name other than your own legal name
  • Access to your county register of deeds office, in every county where you'll do business, since that's where the assumed name certificate gets filed
  • A NCDOR sales and use tax registration, if you'll sell taxable goods or services
  • Any activity-specific license or permit your particular business needs (contractors, cosmetologists, food service, and similar regulated trades all have their own requirements)
  • A separate business bank account, recommended even though nothing legally requires one for a sole proprietor

How to Start a Sole Proprietorship in North Carolina: Step by Step

Step 1: Decide on your business name

If you plan to operate under your own legal name, for example "Jane Smith Photography" where Jane Smith is your actual name, you generally don't need to file anything for the name itself. If you want a name that doesn't include your legal name, like "Triangle Photo Studio," that's an assumed name and North Carolina requires you to register it (see Step 2). Before settling on a name, search the Secretary of State's business registry at sosnc.gov's business search to see if another registered entity is already using something close to it. A sole proprietorship's assumed name filing doesn't reserve exclusive rights to that name statewide the way a corporate name does, so this search is about avoiding confusion and potential trademark conflicts, not a formal availability check.

Step 2: File an Assumed Business Name Certificate, if you need one

This is the step most new sole proprietors in North Carolina either skip or don't know about. Under N.C.G.S. 66-71.5, if you're doing business under any name other than your own legal name, you must file an Assumed Business Name Certificate with the register of deeds in every county where you conduct business. This is filed at the county level, not with the Secretary of State. One certificate can list multiple counties, and one filing covers all of them.

The fee is set by the county register of deeds under the state's general instrument recording statute, G.S. 161-10(a)(1): $26 for the first 15 pages plus $4 for each additional page. That fee doesn't change based on how many counties you list on the certificate. The Secretary of State also maintains a statewide searchable database of certificates filed on or after December 1, 2017, at sosnc.gov/divisions/business_registration/assumed_business_names, though the certificate itself is still filed locally.

Step 3: Get an EIN from the IRS (optional, but usually worth it)

A sole proprietor with no employees can legally use their Social Security number for business tax filings. Most people still get a free EIN from the IRS anyway, mainly because banks generally want one to open a business account, and it keeps your SSN off client-facing paperwork like invoices and 1099 forms. If you plan to hire anyone, an EIN isn't optional; you'll need one to report payroll taxes.

Step 4: Register for a Sales and Use Tax Certificate of Registration, if applicable

If your business sells taxable goods or certain services in North Carolina, you need to register with the North Carolina Department of Revenue (NCDOR) before you make your first sale. Registration is free directly through NCDOR at ncdor.gov's sales and use tax registration page. NCDOR specifically warns that third-party websites charging a fee for this registration are often inaccurate or misleading, so go directly to the state site. North Carolina's state sales tax rate is 4.75%, and most counties add a local rate on top of that.

Step 5: Check what licenses and permits your specific business needs

North Carolina doesn't have one general state business license that covers every business. Licensing here is scattered across individual boards and agencies depending on your profession or activity: contractors, cosmetologists, restaurants, and dozens of other trades each have their own licensing body, and many ordinary service or product businesses need no state license at all. If you're not sure what applies to your business, Business Link North Carolina (BLNC) is a free service through the Department of Commerce that will walk through your specific situation with you. Call 1-800-228-8443. Don't forget to check your city or county too. Home-based businesses in particular sometimes need a local home occupation permit or zoning sign-off that has nothing to do with state requirements.

Step 6: Open a separate business bank account

Nothing in North Carolina law requires a sole proprietor to keep a separate bank account, but skipping this step tends to cause problems later, both for bookkeeping and for proving business expenses if you're ever audited. Most banks will ask for your EIN (or SSN) and, if you have one, your Assumed Business Name Certificate before opening the account.

Step 7: Understand your ongoing tax obligations

As a North Carolina sole proprietor, business profit passes through to your personal return and is taxed at North Carolina's flat individual income tax rate, which is 3.99% for taxable years after 2025 (down from 4.25% in 2025). There's no separate corporate income tax or franchise tax on a sole proprietorship since it isn't a corporation or an LLC electing corporate tax treatment. You'll still owe federal self-employment tax on top of income tax, and you'll generally need to make quarterly estimated payments at both the state and federal level once you owe more than a small threshold. A CPA can confirm your specific estimated payment schedule.

Step 8: Consider (but don't assume you need) business insurance

General liability insurance isn't legally required for most North Carolina sole proprietors, but it's worth pricing out early, especially since a sole proprietorship offers no liability separation between you and the business. Depending on your industry, a client or landlord may require proof of coverage before you can even sign a contract or lease.

Tips and Common Mistakes to Avoid

  • Skipping the Assumed Business Name Certificate. This is the most common gap. If you're operating under any name other than your own, file it with the register of deeds in each county where you do business before you start advertising under that name.
  • Assuming "sole proprietor" means "no licenses needed." The absence of a general state business license doesn't mean your specific trade is unregulated. Call BLNC at 1-800-228-8443 if you're unsure.
  • Mixing personal and business money. Without a separate account, it becomes hard to track deductible expenses and even harder to demonstrate legitimate business activity if the IRS or NCDOR ever asks.
  • Underestimating personal liability exposure. A sole proprietorship gives you none of the liability protection an LLC does. If that risk doesn't fit your business, forming an LLC (North Carolina's Articles of Organization filing fee is $125, plus a $200 annual report each year after) is worth comparing before you commit.
  • Forgetting local zoning or home occupation rules. State-level simplicity doesn't override city or county requirements, particularly for home-based businesses.
  • Paying a third-party site for sales tax registration. NCDOR registration is free. If a site is charging you for it, you're likely on the wrong site.

What You Can Generally Expect

In most cases, a straightforward North Carolina sole proprietorship with no employees and no trade name can be operating within a day or two, since there's no state formation filing to wait on. If you need an Assumed Business Name Certificate, processing time will typically depend on your county's register of deeds office rather than any state timeline. Sales tax registration through NCDOR is generally quick once submitted, though you should confirm current processing times on the NCDOR site since they can shift. Results and timelines may vary by county, industry, and individual circumstances, so treat these as general expectations rather than guarantees.

Frequently Asked Questions

Do I have to register a North Carolina sole proprietorship with the Secretary of State?

No. Starting a sole proprietorship in North Carolina doesn't involve filing a formation document with the Secretary of State the way an LLC or corporation would. Registration only comes into play at the county level, and only if you're using a trade name.

What does it cost to start a sole proprietor business in North Carolina?

If you operate under your own legal name and don't need any special licenses, the direct state and county costs can be minimal to none. The main potential cost is the Assumed Business Name Certificate fee ($26 for the first 15 pages, $4 per additional page, set under G.S. 161-10(a)(1)), plus whatever fees apply to any activity-specific license your business needs.

Can a North Carolina sole proprietor have employees?

Yes. Hiring employees doesn't change your business structure, but it does add obligations, including getting an EIN, registering for state withholding tax, and carrying workers' compensation insurance in most cases. A CPA can walk through what applies once you're ready to hire.
