Wyoming Certificate of Authority: Requirements, Penalties, and Reinstatement

Any business formed outside Wyoming that plans to operate in the state needs a Wyoming Certificate of Authority from the Secretary of State before it starts doing business there. The requirement applies to foreign corporations, LLCs, limited partnerships, and nonprofits organized under another state’s or country’s laws. Register before you begin operating; the price of waiting is a $5,000 penalty, 18% annual interest on unpaid fees and taxes, and the loss of your right to sue in Wyoming courts.

Who Has to Register

Wyoming law bars a foreign corporation from transacting business in the state until it holds a certificate of authority from the Secretary of State.¹ Foreign LLCs follow the same registration process,² and limited partnerships and foreign nonprofits face the same requirement if they carry on business activity in Wyoming.

The threshold question is whether you are “transacting business.” Maintaining an office, employing workers in the state, or regularly generating revenue from Wyoming customers all point toward registration. The more sustained and deliberate the presence, the more likely the state considers you to be transacting business.

Activities That Don’t Trigger Registration

The statute carves out several activities that do not require a Certificate of Authority. You can hold Wyoming bank accounts, defend or settle lawsuits in the state, and complete isolated transactions (finished within 30 days and not part of a pattern) without registering.¹ A foreign entity that only participates in a Wyoming company as an organizer, manager, or member does not need to register for performing those duties. The exception is narrow: if that same entity also conducts its own independent business in Wyoming, it still needs to register.

How to Apply

You apply by filing an application with the Wyoming Secretary of State.³ The application lists your company’s legal name, the state or country where it was formed, the address of its principal office, and the date it was incorporated or organized.⁴

If your entity’s name conflicts with one already on file or doesn’t meet Wyoming’s naming rules, you have to adopt a fictitious name and deliver a certified copy of a board resolution approving it.⁵

Registered Agent

Every foreign entity must appoint a registered agent with a physical street address in Wyoming where the agent can accept service of process in person.⁶ The agent is either an individual at least 18 years old who lives in Wyoming or a business authorized to operate in the state. A signed consent from the agent must accompany the application,⁴ and that consent must include the entity name, a statement of voluntary acceptance, and the agent’s printed name, title, signature, and date.⁷

If you don’t have a contact in Wyoming, commercial registered agent services handle this. Fees commonly run between $35 and $400 per year, depending on the provider and level of service.

Certificate of Existence

You also submit a Certificate of Existence (sometimes called a Certificate of Good Standing) from your home state or country, authenticated by the official who maintains corporate records there. The certificate cannot be dated more than 60 days before you file in Wyoming.⁴ Most states charge between $5 and $25 for this document. Factor in the turnaround from your home state when you plan your filing date.

Fee and Processing

The filing fee for a foreign LLC’s Certificate of Authority is $150.⁸ Fees for other entity types differ; check the Secretary of State’s current schedule for your entity. Wyoming does not offer expedited processing. Applications are handled in the order they are received, so build in time if you need to begin operations by a specific date.

What Happens If You Skip Registration

The financial consequences are steep. A foreign corporation that transacts business in Wyoming without a certificate owes all the fees and license taxes it would have paid had it registered on time, plus 18% annual interest on those amounts. The state then adds a flat $5,000 penalty and can bill you for reasonable audit expenses and attorney fees it incurs chasing the matter.⁹ The Secretary of State can refuse to issue a certificate until every dollar is paid.

There’s also a courtroom consequence that catches many businesses off guard. An unregistered foreign entity cannot file or maintain a lawsuit in any Wyoming court. If you’re owed money under a Wyoming contract and you haven’t registered, you can’t sue to collect until you’ve put your certificate in order.⁹ You can still defend yourself if someone sues you, but you lose the ability to bring your own claims.

Wyoming regulations set a 45-day window: the statutory penalty applies to any business entity that has been conducting business without authority for 45 days or more, with an exception for nonprofits.¹⁰

Staying in Good Standing

Wyoming does not require you to renew the Certificate of Authority itself. Instead, every registered foreign entity files an annual report and pays a license tax each year. The report is due on the first day of the anniversary month of your original registration.¹¹ Register on September 20 and your report is due every September 1 after that.

The license tax is $60 or two-tenths of one mill on the dollar ($0.0002) of your capital, property, and assets located in Wyoming, whichever is greater.¹² In practice, the $60 minimum applies until your Wyoming-located assets exceed $300,000. Above that, you pay the calculated amount. Banks, insurance companies, and savings and loan associations are exempt. The Secretary of State’s office uses total assets from your balance sheet with adjustments for depreciable property, land, and depletable resources, which are reported at assessed value rather than book value.¹³

Amending the Certificate

Some changes require an amended certificate of authority. Wyoming law triggers the amendment requirement when you change your corporate name, the period of your entity’s duration, or your state or country of incorporation.¹⁴ The filing fee is $60.¹⁵

Changes to your registered agent or registered office are handled separately under Wyoming’s registered agent statutes, not through the amendment process. If your agent resigns or your office address changes, you have 30 days to notify the Secretary of State.¹⁶ Missing that deadline is itself a ground for revocation.

Revocation and Reinstatement

The Secretary of State can start revocation proceedings for several reasons:

Missing an annual report or license tax payment when due.
Letting your registered agent lapse or failing to keep a physical registered office in Wyoming.
Not notifying the Secretary of State within 30 days when your agent changes or resigns, or your office is discontinued.
Having an officer, director, or agent sign a document they knew was materially false.
Being unreachable through either your registered agent or the Secretary of State acting as agent for process.

These grounds are set out in Wyoming’s revocation statute.¹⁶ Before formal revocation, the Secretary of State may classify the entity as “delinquent awaiting administrative revocation,” which serves as a warning.

Once grounds exist, you receive written notice and have 60 days to cure the problem or show the Secretary of State that the alleged ground doesn’t exist.¹⁷ Ignore the notice and the Secretary of State signs a certificate of revocation. You can appeal in court within 30 days after the revocation certificate is served.¹⁸

Getting Reinstated

You have two years from the effective date of revocation to apply for reinstatement. If you were revoked for missed annual reports or unpaid taxes, you pay all delinquent fees and taxes plus a reinstatement certificate fee set by the Secretary of State. If you were revoked for failing to maintain a registered agent, the reinstatement fee is $250 on top of any delinquent amounts. Either path requires proof that your company is currently in good standing in its home state.¹⁹ The Secretary of State can deny reinstatement if the corporation was involved in a fraud investigation or other legal violations.

After two years, reinstatement is off the table. You would have to file a brand-new application for a Certificate of Authority. And if you kept operating in Wyoming during the lapsed period, you face the full penalty for transacting business without authority.¹⁹

Withdrawing From Wyoming

When your business no longer operates in Wyoming, don’t simply stop filing. You must obtain a certificate of withdrawal. The withdrawal application states that your entity is no longer transacting business in Wyoming, surrenders its authority, revokes your registered agent’s authority, and designates the Secretary of State as your agent for service of process for any claims arising from the period when you were authorized. You provide a mailing address and email for forwarding any process served after you leave.²⁰

The filing fee is $60, and your entity must be active and in good standing when you file.²¹ Processing takes up to 15 business days, and the form is submitted by mail. The good-standing requirement is the part people miss. If you owe back annual reports or taxes, clear those first; Wyoming won’t let you leave cleanly until you do.
