An out-of-state company that does business in Minnesota without registering must register before it can sue in a Minnesota court, and a corporation can face a State of Minnesota penalty whose cap grows each month it keeps operating unregistered. Its Minnesota contracts stay valid, it can still defend a lawsuit, and its owners do not lose their liability shield for that reason. A plaintiff can also serve it through the Minnesota Secretary of State.

Minnesota sets these rules by statute, one set per type of company. Chapter 303, starting with Minn. Stat. § 303.03, governs corporations formed elsewhere (“foreign corporations”). Its definitions set that reach: “Corporation” means “a corporation formed for profit and includes a cooperative,” and a foreign corporation does not include “insurance companies as defined by section 60A.02” or the other entities the definition lists (Minn. Stat. § 303.02, subds. 2 and 4). Minn. Stat. §§ 322C.0801 to 322C.0810 govern foreign limited liability companies (LLCs), and separate sections cover limited partnerships and limited liability partnerships. The registration is called a certificate of authority, or for a limited liability partnership, a statement of foreign qualification. This page covers companies formed outside Minnesota; a Minnesota company expanding into another state answers to that state’s statute. It sits with my other Minnesota business compliance guides.

What happens when an out-of-state company does business in Minnesota without registering?

An unregistered company loses access to Minnesota courts as a plaintiff, faces a possible penalty or injunction from the Attorney General, and can be served through the Secretary of State. Its contracts remain valid and its owners stay protected.

Each consequence comes from the statute for the company’s type:

  • No lawsuits as plaintiff. A foreign LLC transacting business in Minnesota “may not maintain an action or proceeding in this state unless it has a certificate of authority to transact business in this state” (Minn. Stat. § 322C.0808, subd. 1). Minn. Stat. § 303.20 sets the same bar for corporations.
  • Penalty or injunction. A corporation can owe a capped penalty plus a capped amount for each month it keeps transacting business unregistered, recovered in a lawsuit the Attorney General brings (§ 303.20). For an LLC, the Attorney General may sue to stop the business.
  • Service through the Secretary of State. An unregistered LLC “appoints the secretary of state as its agent for service of process for rights of action arising out of the transaction of business in this state” (§ 322C.0808, subd. 4).
  • What stays intact. The failure to register “does not impair the validity of any contract or act” of a corporation (§ 303.20), and the LLC statute says the same (§ 322C.0808, subd. 2).

When does an out-of-state company have to register in Minnesota?

A foreign company must register before it transacts business in Minnesota. A foreign LLC must obtain a certificate of authority “Before transacting business in this state” (Minn. Stat. § 322C.0802), and “No foreign corporation shall transact business in this state unless it holds a certificate of authority so to do” (Minn. Stat. § 303.03).

Neither statute defines transacting business. Both instead list activities that, by themselves, do not count, such as holding internal meetings, “maintaining bank accounts,” collecting debts, and “conducting an isolated transaction completed within a period of 30 days and not in the course of a number of repeated transactions of like nature” (§ 303.03; Minn. Stat. § 322C.0803, subd. 1). The corporate list applies “Without excluding other activities which may not constitute transacting business in this state,” so an activity missing from the list is not automatically covered. The LLC statute adds a rule the corporate statute lacks: owning “income-producing real property or tangible personal property, other than property excluded under subdivision 1,” in Minnesota “constitutes transacting business in this state” (§ 322C.0803, subd. 2). That rule is the Minnesota version of the question in my page on an LLC buying property outside its home state.

Revenue is not the test. When an owner of a pre-revenue out-of-state LLC asked me whether registration could wait, I explained that the question turns on what the company does in Minnesota, not what it earns here. Facts such as a Minnesota office, sales staff working here, or remote employees can trigger foreign registration questions.

Federal law sets an outer limit. Chapter 303 excludes any corporation that, “under the Constitution and statutes of the United States, may transact business in this state without first obtaining a certificate of authority” (Minn. Stat. § 303.02, subd. 4). The U.S. Supreme Court upheld Minnesota’s dismissal of a suit by a North Dakota customs broker that had “localized its business” in Minnesota (Union Brokerage Co. v. Jensen, 322 U.S. 202 (1944)). Later, applying Mississippi’s similar statute to a cotton merchant with “no office in Mississippi” and no employees regularly operating there, the Court held that “Mississippi’s refusal to honor and enforce contracts made for interstate or foreign commerce is repugnant to the Commerce Clause” (Allenberg Cotton Co. v. Pittman, 419 U.S. 20 (1974)). Under these two decisions, the more localized a company’s Minnesota activity, the weaker an interstate-commerce argument against registering.

How does the bar on bringing a lawsuit work?

An unregistered foreign corporation transacting business in Minnesota cannot bring a Minnesota lawsuit without first registering. Minn. Stat. § 303.20 says it shall not “be permitted to maintain an action in any court in this state until such corporation shall have obtained a certificate of authority.”

The bar follows the claim. No action may be maintained “by any successor or assignee of such corporation on any right, claim, or demand arising out of the transaction of business by such corporation in this state” until the corporation, or a corporation that acquired substantially all its assets, obtains a certificate (§ 303.20). The statute adds: “If such assignee shall be a purchaser without actual notice of such violation by the corporation, recovery may be had to an amount not greater than the purchase price.” I suggest that anyone buying an out-of-state company’s Minnesota receivables confirm the seller is registered, because the bar reaches a successor or assignee.

The other entity types carry the same bar in their own words: a foreign LLC (§ 322C.0808, subd. 1), a foreign limited partnership (Minn. Stat. § 321.0907(b)), and a foreign limited liability partnership that lacks “in effect a statement of foreign qualification” (Minn. Stat. § 323A.1103(a)). The bar is real in practice: in Union Brokerage, the Minnesota Supreme Court reversed a judgment the unregistered company had won and ordered its suit dismissed, and the U.S. Supreme Court affirmed. The statutes do not bar the company from defending a suit someone else brings.

What penalties can the State of Minnesota impose?

A foreign corporation that transacts business without a certificate “shall forfeit and pay to this state a penalty, not exceeding $1,000, and an additional penalty, not exceeding $100, for each month or fraction thereof during which it shall continue to transact business in this state without a certificate of authority therefor” (Minn. Stat. § 303.20).

The penalty is recovered “by an action, in the name of the state, brought by the attorney general,” in a county where the corporation has done business, has property, or has a place of business. In State ex rel. Spannaus v. Mecca Enterprises, Inc., 262 N.W.2d 152 (Minn. 1977), the Attorney General’s suit against a Texas corporation ended in an injunction against doing business without a certificate and “a penalty of $500 for failing to procure a certificate of authority.”

The LLC sections set no counterpart to the corporate money penalty. Instead, “The attorney general may maintain an action to enjoin a foreign limited liability company from transacting business in this state” in violation of those sections (Minn. Stat. § 322C.0809). The Attorney General has the same power to “restrain a foreign limited partnership” (Minn. Stat. § 321.0908). For an LLC, the larger costs are the lawsuit bar and the risk of missing a suit served through the Secretary of State, covered below.

Why do the company’s contracts and owners stay protected?

Minnesota’s statutes keep the company’s deals and its owners’ liability shield intact. For a corporation, failing to register “does not impair the validity of any contract or act of such corporation, and shall not prevent such corporation from defending any action in any court of this state” (Minn. Stat. § 303.20).

The LLC statute says the same about contracts and defenses (Minn. Stat. § 322C.0808, subd. 2). It also protects the owners: “A member, manager, or governor of a foreign limited liability company is not liable for the debts, obligations, or other liabilities of the company solely because the company transacted business in this state without a certificate of authority” (§ 322C.0808, subd. 3). Partners of a foreign limited partnership get matching protection under Minn. Stat. § 321.0907(d). For a limited liability partnership, “A limitation on personal liability of a partner is not waived solely by transacting business in this state without a statement of foreign qualification” (Minn. Stat. § 323A.1103(c)). Section 303.20, which lists the consequences for an unregistered foreign corporation, imposes no liability on its shareholders.

So a customer cannot escape an invoice by pointing to the missing registration. The same customer can, however, stall the company’s own collection suit by pointing to that same missing registration.

How can a Minnesota plaintiff serve an unregistered company?

A plaintiff can serve an unregistered company through the Minnesota Secretary of State. A foreign LLC that transacts business without a certificate “appoints the secretary of state as its agent for service of process for rights of action arising out of the transaction of business in this state” (Minn. Stat. § 322C.0808, subd. 4).

Corporations reach the same place by a different route. Under Minn. Stat. § 5.25, subd. 4(b), “A foreign corporation is considered to be doing business in Minnesota if it makes a contract with a resident of Minnesota to be performed in whole or in part by either party in Minnesota, or if it commits a tort in whole or in part in Minnesota against a resident of Minnesota.” Those acts count as appointing the Secretary of State to receive process in suits arising from the contract or tort.

The danger for an unregistered company is the mailing address. For a company never authorized to do business in Minnesota, the Secretary of State “shall immediately cause a copy of a service of process to be forwarded by certified mail,” sent “at the address provided by the party submitting the document for service of process” (§ 5.25, subd. 6). If the plaintiff has an old address, the company may not learn of the suit before its time to answer under § 5.25, subd. 7 runs out. A registered company instead receives papers through its own registered agent at the address it keeps on file.

What happens when a registered company misses its annual renewal?

A registered foreign company that skips its annual renewal loses its certificate and is back in the unregistered position. For a corporation, the Secretary of State “shall revoke the certificate of authority” for failure to file the annual form (Minn. Stat. § 303.17, subd. 3), and “No further notice to the corporation is required” (§ 303.17, subd. 4).

The renewal is modest: “The corporation will submit a $115 fee with the annual renewal” (Minn. Stat. § 303.14, subd. 1). Missing it is costlier. Once the certificate of revocation issues, “the authority of the corporation to transact business in this state shall cease” (§ 303.17, subd. 5), which reopens the lawsuit bar and the penalty exposure. Foreign LLCs face the same rule for failing “to file an annual renewal” (Minn. Stat. § 322C.0806, subds. 1, 3, and 5), and the Secretary of State must “make the names of the revoked foreign limited liability companies available in an electronic format” (§ 322C.0806, subd. 4). A counterparty can look a revoked company up.

A revoked corporation “may reinstate that authority by filing an annual renewal and the fee required by subdivision 2” (Minn. Stat. § 303.19, subd. 1). That fee: the corporation “shall pay to the commissioner of management and budget $500 before it may be reinstated” (§ 303.19, subd. 2). My page on annual renewal deadlines and penalties covers the calendar side.

How does a company fix a missed registration?

A company fixes a missed registration by filing its application with the Minnesota Secretary of State now. A foreign LLC files an application “together with a total fee of $185” (Minn. Stat. § 322C.0802), and a corporation files the application described in Minn. Stat. § 303.06.

The filing has three practical requirements:

  • A Minnesota registered office and agent. “Every non-Minnesota corporation shall have a registered office and shall have a registered agent” (Minn. Stat. § 303.10), and the LLC application must name “the company’s initial registered office and agent for service of process in this state” (§ 322C.0802). My page on the registered office and registered agent explains the role.
  • Consent to service. The corporate application states “that it irrevocably consents to the service of process upon it as set forth in section 5.25” (§ 303.06, subd. 1).
  • A usable name. A foreign LLC whose name conflicts with Minnesota’s name rules “may not obtain a certificate of authority until it adopts, for the purpose of transacting business in this state, an alternate name” (Minn. Stat. § 322C.0805, subd. 1).

The corporate lawsuit bar lasts “until such corporation shall have obtained a certificate of authority” (§ 303.20). A separate bar sits in the tax chapter: a corporation required to file a notice of business activities report “does not have any cause of action upon which it may bring suit under Minnesota law, except for issues related to its Minnesota tax liability, unless the corporation has filed a notice of business activities report,” and the court “must excuse” a late report if the corporation “has paid all taxes, interest, and civil penalties due the state for all periods, or provided for payment of them by adequate security or bond approved by the commissioner” (Minn. Stat. § 290.371, subd. 4). The monthly penalty in § 303.20 runs only for months the corporation “shall continue to transact business” without a certificate, so under that wording registering stops new months from adding to it. The statute does not say registering erases the past exposure.

I suggest weighing the filing cost against the cost of answering the question. When an owner asked me whether storing inventory with a Minnesota fulfillment warehouse required registration, I pointed out that warehousing is not on § 303.03’s list and that registering might cost less than a legal opinion on whether it was required. The step-by-step filing is in my guide to applying for a Minnesota certificate of authority. A company that later leaves Minnesota can file a withdrawal stating “that it has no property located in this state and has ceased to transact business therein” (Minn. Stat. § 303.16, subd. 2; Minn. Stat. § 322C.0807, subd. 2).

Can we sue a Minnesota customer for an unpaid invoice if we never registered?

Not until your company obtains a certificate of authority, if it transacted business here without one. Minn. Stat. § 303.20 bars suit ‘until such corporation shall have obtained a certificate of authority,’ and § 322C.0808 bars an unregistered foreign LLC. The invoice stays valid, and the company may defend. A corporation owing a notice of business activities report also cannot sue on the invoice ‘unless the corporation has filed a notice of business activities report,’ and a court ‘must excuse’ a late report if it ‘has paid all taxes, interest, and civil penalties due the state for all periods’ (§ 290.371).

Will our owners be personally liable because the company did not register?

No, not for that reason alone. Minn. Stat. § 322C.0808 says a member, manager, or governor of a foreign LLC is not liable for the company’s debts solely because it transacted business in Minnesota without a certificate of authority. Minn. Stat. § 321.0907 and § 323A.1103 give partners of foreign limited partnerships and limited liability partnerships the same protection. Minn. Stat. § 303.20, which sets the consequences for an unregistered foreign corporation, imposes no liability on shareholders.

Is one contract with a Minnesota company enough to require registration?

Not by itself, if it is an isolated transaction completed within the period the statutes set and not part of repeated deals of the same kind. Minn. Stat. § 303.03 and § 322C.0803 both list ‘conducting an isolated transaction completed within a period of 30 days and not in the course of a number of repeated transactions of like nature’ as an activity that alone is not transacting business. Separately, Minn. Stat. § 5.25 treats a foreign corporation’s contract with a Minnesota resident, performed partly in Minnesota, as consent to service through the Secretary of State.

Does registering with the Secretary of State settle our Minnesota tax obligations?

No. Registration and taxation are separate questions under Minnesota law. Minn. Stat. § 303.03 states that it ‘does not establish standards for those activities that may subject a foreign corporation to taxation,’ and Minn. Stat. § 322C.0803 says its list of activities does not decide service of process, taxation, or regulation under other Minnesota law. Whether a company owes Minnesota tax filings is answered under the tax statutes, separately from whether it must hold a certificate of authority.

Do employees working in Minnesota mean we have to register?

Not necessarily on that fact alone. In State ex rel. Spannaus v. Mecca Enterprises, Inc., 262 N.W.2d 152 (Minn. 1977), the Minnesota Supreme Court affirmed a $500 penalty and an injunction against a Texas corporation whose door-to-door sales crews were found to be its employees. On rehearing, the court said that ’the bare fact that the solicitors here were employees would not necessarily require a finding that Mecca was doing business in the state,’ and that the other facts and circumstances adequately supported the finding.

Does an LLC that only owns Minnesota rental property need to register?

Yes, under the LLC statute. Minn. Stat. § 322C.0803 provides that ’the ownership in this state of income-producing real property or tangible personal property, other than property excluded under subdivision 1, constitutes transacting business in this state’ for the foreign LLC rules. A rental building is income-producing real property. Because Minn. Stat. § 322C.0802 requires the certificate before transacting business, an out-of-state LLC that owns one should obtain it before it starts renting, even with no office or employees here.

What This Means for an Out-of-State Owner

For a company formed outside Minnesota, skipping registration closes the Minnesota courthouse door when a customer here stops paying, and it lets a plaintiff serve the company through the Secretary of State at whatever address the plaintiff supplies. A corporation also risks “a penalty, not exceeding $1,000, and an additional penalty, not exceeding $100, for each month or fraction thereof” it keeps transacting business unregistered, recovered “by an action, in the name of the state, brought by the attorney general.” The contracts and the owners’ liability shield survive. Registering takes a filing with the Secretary of State plus a registered agent and an annual renewal. Whether a particular operation is transacting business in Minnesota turns on its facts, and my Minnesota compliance practice handles that question.
