What Is a Foreign LLC in Wyoming?

A foreign LLC is a limited liability company formed in one state that wants to do business in a different state. "Foreign" simply means out-of-state — not international.

If your LLC was formed in any state other than Wyoming, it is a "foreign LLC" from Wyoming's perspective. To legally operate in Wyoming, you must obtain a Certificate of Authority from the Wyoming Secretary of State. For the full picture on Wyoming LLC costs and rules, see our Wyoming LLC compliance hub.

Wyoming Context: Wyoming is famous for being the birthplace of the LLC (1977). Many entrepreneurs form Wyoming LLCs from other states for asset protection — that's the opposite situation (domestic Wyoming LLC, foreign registration in home state). This guide covers businesses that need to register a non-Wyoming LLC to operate IN Wyoming.

When Must You Register as a Foreign LLC in Wyoming?

A foreign entity may not transact business in Wyoming until it obtains a Certificate of Authority. Activities that typically require registration include:

Activities That Require Registration

  • Maintaining a physical office, warehouse, or store in Wyoming
  • Hiring employees based in Wyoming
  • Regularly executing or performing contracts in Wyoming
  • Owning, leasing, or managing real property in Wyoming
  • Operating a retail or service location in Wyoming
  • Generating significant, ongoing revenue from Wyoming business activities

Activities That Typically DON'T Require Registration

  • Having Wyoming customers who purchase online (no Wyoming presence)
  • Holding internal meetings of members or managers in Wyoming
  • Maintaining a Wyoming bank account
  • Selling through independent contractors
  • Soliciting orders that require acceptance outside Wyoming before becoming contracts
  • Conducting an isolated transaction completed within 30 days

These exclusions come from the Wyoming Secretary of State's official guidance on whether you need a Certificate of Authority.

When in Doubt: Consult a Wyoming attorney. The $150 registration fee is a small price compared to the $5,000 penalty for unauthorized business. Registering proactively is always the safer choice.

Registration Process (Mail Only)

Important: Unlike domestic Wyoming LLCs (which can be formed online instantly), foreign LLC registrations must be submitted by mail. Wyoming does not currently offer online filing for foreign entities.

Step-by-Step Process

  1. Check name availability at wyobiz.wyo.gov to confirm your LLC name is available in Wyoming. If not, select an alternate name for Wyoming use.
  2. Obtain an original certificate of existence/good standing from your home state's Secretary of State. It must be dated no more than 60 days before you file in Wyoming, or the office will reject it.
  3. Select a Wyoming registered agent with a physical Wyoming street address (no drop boxes). Since you're operating in Wyoming without living there, a professional registered agent service is typically required, and the agent must sign a Consent to Appointment.
  4. Download the Foreign LLC Application for Certificate of Authority from sos.wyo.gov/forms/business/fllc/. The Consent to Appointment by Registered Agent is part of the same packet.
  5. Complete the form with your LLC name as organized, state and date of organization (matching the good-standing certificate), period of duration, registered agent name and physical address, the date you began (or will begin) doing business in Wyoming, and an authorized signature.
  6. Mail the completed form, the signed registered-agent consent, the good-standing certificate, and a $150 check or money order payable to "Wyoming Secretary of State" to the address on the form.
  7. Wait up to 15 business days for processing from the date of receipt. Wyoming does not offer expedited processing.

Required Documents

Your foreign LLC registration package must include:

  • Completed Application for Certificate of Authority — signed by an authorized member, manager, or other authorized individual
  • LLC name as organized in your home state (plus a Use of Fictitious Name form if that name is unavailable in Wyoming)
  • State and date of organization (must match the good-standing certificate)
  • Original certificate of existence/good standing from your home state, dated no more than 60 days before filing
  • Consent to Appointment by Registered Agent — signed by your Wyoming registered agent
  • Wyoming registered agent name and physical Wyoming address
  • $150 filing fee (check or money order — no credit cards by mail)

Ongoing Requirements After Registration

Once registered, your foreign LLC has the same annual obligations as a domestic Wyoming LLC:

  • Annual report license tax: $60 minimum (or $0.0002 on Wyoming assets, whichever is greater), due the first day of your anniversary month
  • Annual report: File via wyobiz.wyo.gov (online filing is allowed for annual reports even though the initial registration is mail-only)
  • Registered agent: Maintain an active Wyoming registered agent at all times
  • Update Wyoming on home-state changes: If your LLC's name changes in your home state, notify Wyoming
  • Withdrawal when done: File a Certificate of Withdrawal when you stop doing business in Wyoming

The mechanics of the annual report are identical to a domestic LLC — see Wyoming LLC Annual Report 2026 and Wyoming LLC Taxes & Annual Fees 2026 for the full breakdown.

An annual report not paid within 60 days of its due date subjects the entity to dissolution — the same swift 60-day timeline that applies to domestic LLCs. See: Wyoming LLC Late Filing Penalties 2026.

Penalties: $5,000 + 18% Interest

Wyoming's penalty for unauthorized business is among the most significant in the country. Per Wyoming Statute W.S. 17-16-1502(d):

  • $5,000 flat penalty for transacting business without a Certificate of Authority
  • 18% annual interest on all unpaid license taxes and fees for the unauthorized period
  • Cannot maintain lawsuits in Wyoming courts until registered and all back amounts paid
  • Reasonable audit expenses and attorney fees may also be assessed

The $5,000 penalty dwarfs the $150 registration fee. If you're doing business in Wyoming, register first.

Cannot Sue Until Registered: One of the most practical consequences: if you're operating without authority and a customer owes you money, you cannot file a lawsuit in Wyoming courts until you're properly registered AND have paid all back fees and penalties. Register before you have a problem.

Retroactive Registration

If you realize you've been operating without authority, you can register retroactively. Pay all back license taxes plus the $5,000 penalty plus 18% interest. While expensive, this is the path to coming into compliance and regaining the ability to use Wyoming courts.

Frequently Asked Questions

When does an out-of-state LLC need to register in Wyoming?

A foreign entity may not transact business in Wyoming until it obtains a certificate of authority. 'Transacting business' generally means having employees in Wyoming, a physical presence, regularly performing contracts in Wyoming, or owning/managing Wyoming property. The Secretary of State lists activities that do NOT count, including holding internal meetings, maintaining a bank account, selling through independent contractors, securing debts, and conducting an isolated transaction completed within 30 days.

How do I register a foreign LLC in Wyoming?

Complete the Foreign Limited Liability Company Application for Certificate of Authority (filed under W.S. 17-16-1533, available at sos.wyo.gov). You'll need: (1) your LLC's name as organized in your home state, (2) your state of organization and date, (3) the period of duration (usually 'perpetual'), (4) your Wyoming registered agent's name and physical Wyoming address plus a signed Consent to Appointment by Registered Agent, (5) an original certificate of existence/good standing from your home state dated within 60 days, and (6) the $150 filing fee. Submit everything by mail — foreign entity filings cannot be done online.

How long does Wyoming foreign LLC registration take?

Wyoming processes all mailed filings in the order received, with a maximum processing time of 15 business days. Wyoming does not offer expedited processing for any filings. Plan accordingly if you have time-sensitive business needs in Wyoming.

What are the penalties for doing business in Wyoming without registering?

Per Wyoming Statute W.S. 17-16-1502(d), an unregistered foreign entity doing business in Wyoming is liable for: a $5,000 penalty, all unpaid license taxes and fees that would have been due, 18% annual interest on those amounts, plus reasonable audit expenses and attorney fees. Additionally, the entity cannot maintain any lawsuit in Wyoming courts until it registers, and the Secretary of State may refuse the certificate of authority until all amounts are paid.

Once registered, what ongoing requirements do foreign LLCs have in Wyoming?

Registered foreign LLCs have the same annual obligations as domestic Wyoming LLCs: (1) file the annual report and pay the license tax — $60, or two-tenths of one mill ($0.0002) on Wyoming assets, whichever is greater — due the first day of their anniversary month each year, (2) maintain a Wyoming registered agent at all times, (3) keep Wyoming updated on home-state changes, and (4) file a Certificate of Withdrawal when they stop transacting business. Annual reports unpaid within 60 days of the due date subject the entity to dissolution.

Can I use the same name for my foreign LLC in Wyoming?

If your LLC's home state name is already in use in Wyoming or is deceptively similar to an existing Wyoming entity, you'll need to use an alternative name in Wyoming. You can designate this alternate name on your Certificate of Authority. Check Wyoming's business name database at wyobiz.wyo.gov before submitting your application.
