Doing Business in Another State: Foreign Qualification, Certificate of Authority Fees and Penalties

The short answer

A company that transacts business in a state other than the one where it was formed generally must first qualify there as a foreign entity by filing an Application for Certificate of Authority and appointing a local registered agent. In North Carolina the fee is $250 for both corporations and LLCs, and you attach a certificate of existence from your home state dated within six months. Doing business in North Carolina without authority bars the company from suing in NC courts and carries a civil penalty of $10 per day, up to $1,000 per year, plus the fees and taxes it should have paid. Qualification and state tax nexus are separate questions.

Who this applies to

North Carolina residents running a Wyoming or Delaware LLC. The company was formed elsewhere, but the office, staff and customers are in North Carolina.

Family businesses moving to North Carolina from New York or California. You choose between qualifying as a foreign entity and converting or domesticating the company into North Carolina.

Restaurants and retailers opening locations in several states. Each state with a location usually requires qualification.

U.S. subsidiaries of Chinese parent companies. A Delaware subsidiary that leases an office and hires staff in North Carolina must qualify there.

When you must qualify

You must qualify when you transact business in the state; North Carolina law does not fully define the term but lists activities that do not, by themselves, count. The lists in G.S. 55-15-01(b) for corporations and G.S. 57D-7-01(b) for LLCs are essentially the same.

Activities that alone are not transacting business: maintaining or defending lawsuits and settling claims; holding owner or board meetings; keeping bank accounts or borrowing money; maintaining transfer agents for ownership interests; soliciting orders that must be accepted outside the state; making or investing in loans without an in-state office; securing and collecting debts; interstate commerce; an isolated transaction completed within six months that is not one of a series; selling through independent contractors; and owning real or personal property.

Situations that usually require qualification: an office, store or warehouse in the state, ongoing employees there, or regularly providing services there. The statute says the list does not exclude other activities, so facts matter.

Owning property: Owning property alone is not transacting business, but how much leasing and management activity crosses the line is a fact question worth reviewing.

How to qualify: North Carolina as the example

File an Application for Certificate of Authority with the NC Secretary of State; the fee is $250.

Certificate of existence: Attach an original good standing certificate from your home state, issued within six months. Photocopies are not accepted.

Registered agent: You need a North Carolina registered agent and office. The agent must be an NC resident or an entity authorized to do business in the state.

Name: If your name is already taken in North Carolina, you adopt a fictitious name for use there; an LLC attaches the managers' resolution adopting it.

Every year after: File the NC annual report ($200 for LLCs) and keep filing in your home state.

Other states: Delaware charges $245 to qualify a foreign corporation and $200 to register a foreign LLC. Wyoming charges $150 for a certificate of authority for corporations and LLCs.

What happens if you do not qualify

Your contracts stay valid, but you cannot sue in North Carolina, and penalties and back fees apply.

No lawsuits: An unqualified foreign company cannot maintain a proceeding in NC courts unless it qualifies before trial. It can still defend itself.

Civil penalty: $10 per day, up to $1,000 for each year or part of a year.

Back fees and taxes: You owe all fees and taxes you would have paid if you had qualified, plus interest and penalties.

In practice: Banks, landlords, public contracts and platforms often ask for proof of registration in North Carolina.

Qualification and state tax are separate

Whether you must register with the Secretary of State and whether you owe sales, income or franchise tax are tested differently.

Sales tax: Sellers with a physical presence in North Carolina collect tax. Remote sellers must register once gross sales sourced to North Carolina exceed $100,000 in the current or previous calendar year. The 200-transaction test was repealed effective July 1, 2024.

Income and franchise tax: Federal P.L. 86-272 protects only companies whose in-state activity is limited to soliciting orders for tangible goods, and only from income tax. North Carolina franchise tax still applies to corporations doing business in the state.

Payroll: Employees working in a state generally require withholding and unemployment registration there.

BOI: Under FinCEN's current rules, companies formed in the U.S. no longer report beneficial ownership information. Companies formed abroad, such as in China, and registered to do business in a U.S. state still must report.

A simple example

This is simplified.

Mr. Wang lives in Cary. In 2025 he formed a Wyoming LLC to run an online store from home and hired one North Carolina employee in 2026. With a fixed place of business and an employee in North Carolina, the LLC should qualify: a $250 filing fee and an NC registered agent, then a $200 NC annual report each year, while still paying Wyoming's report (at least $60) and its Wyoming agent.

If the business will only operate in North Carolina, he can also consider converting the LLC to a North Carolina LLC and filing in one state only. The right choice depends on whether the Wyoming entity still matters for banks and contracts.

Common mistakes

"A Wyoming LLC is cheap wherever I operate." If you really operate in North Carolina, you also register and file there, which often costs more in total.

"Qualifying means I owe income tax there." Tax obligations follow separate rules.

"I'm not registered, so I don't collect that state's sales tax." Sales tax depends on presence and sales volume, not registration.

"I'll register later." Late registration brings penalties and back fees and can stall a lawsuit.

What to do and when

Before you start operating in a new state: Check the activity list and line up a registered agent.

Within a month before filing: Order a certificate of existence from your home state (North Carolina requires one issued within six months).

After approval: Update your bank, contracts and licenses with the new registration.

Every year: NC LLC annual report by April 15, plus your home-state filing.

Once you hire or sell: Register for NC withholding, unemployment insurance and sales tax as needed.

Questions this article answers

Does my Wyoming LLC need to register in North Carolina?

If the LLC has an office, employees or ongoing operations in North Carolina, it generally must qualify. File an Application for Certificate of Authority with the NC Secretary of State ($250) with a Wyoming certificate of existence issued within six months, and appoint an NC registered agent. You then file NC annual reports while continuing Wyoming filings.

What activities do not count as doing business in North Carolina?

The statutes list lawsuits and settlements, internal meetings, bank accounts and borrowing, soliciting orders accepted outside the state, interstate commerce, an isolated transaction completed within six months, selling through independent contractors, and owning property, among others. The list is not exhaustive, so the facts matter.

What happens if I do business without qualifying?

In North Carolina, an unqualified foreign company cannot maintain a lawsuit in state court until it qualifies before trial, though it can defend itself. It faces a civil penalty of $10 per day up to $1,000 per year, plus the fees and taxes it should have paid with interest. Its contracts remain valid.

If I qualify in a state, do I owe tax there?

Not necessarily. North Carolina sales tax depends on physical presence or more than $100,000 of NC-sourced sales; income tax may be limited by P.L. 86-272, but NC franchise tax is not; and in-state employees create payroll obligations.

Should I qualify or move my company when I relocate?

Both work. Qualifying keeps the original entity and means filing in two states; converting or domesticating makes it a North Carolina entity with one set of filings. Consider the effect on banks, contracts and investors first.
