Registering a Foreign Limited Partnership in Colorado

A limited partnership whose charter came from outside Colorado must be on the Secretary of State's record before it transacts business here. Colorado handles that with a single online statement, charges one fee and asks for nothing from the home state. This guide walks through the statement, the agent rules for a partnership with no Colorado presence, and the consequences of staying off the record.

How Colorado treats a limited partnership from elsewhere

Colorado calls any limited partnership organized elsewhere foreign, and the label also covers a limited liability limited partnership. Section 7-62-902 of the Colorado Revised Statutes says part 8 of article 90, the part about foreign entities, covers both. It is the same part used for corporations and LLCs, so a partnership uses the Statement of Foreign Entity Authority rather than a partnership-specific form.

Filing does not re-form the partnership. Its home law continues to govern how it is organized, how it runs and what its owners are liable for (section 7-90-805), which includes the duties of general and limited partners. Colorado gives it the rights and duties of a similar Colorado limited partnership, with no extra privileges.

One boundary to know about: part 8 does not reach a foreign general partnership unless it is a limited liability partnership. A limited partnership is covered.

Does your partnership need to file?

Section 7-90-801 bars a foreign entity from transacting business or conducting activities in Colorado until its statement is filed. Colorado never defines that phrase. Instead the statute lists things a foreign entity can do without being treated as transacting business, and it says the list is not a complete one.

Not enough on their own

  • Litigating or settling a claim in its own interest
  • Partner meetings and other internal affairs
  • A bank account
  • An agent for transferring its own partnership interests
  • Using independent contractors to sell
  • Orders solicited here that need acceptance elsewhere to become contracts
  • Taking on or lending out debt, including mortgage-type security
  • Collecting what it is owed, or enforcing collateral
  • Owning real or personal property, without more
  • A one-time transaction done within thirty days and unconnected to a series of similar ones
  • Interstate commerce

A partnership that holds a rental building as a passive investment is therefore not caught by the ownership alone. One that runs an office, keeps employees in Colorado or regularly does work here falls outside the list. The Secretary of State declines to answer individual fact patterns, such as a remote worker, and suggests asking an attorney or business advisor. That is wise for any partnership sitting near the line.

The statement, the fee and how it is submitted

The document to file is the Statement of Foreign Entity Authority. The paper form is listed as not available, and the PDF the Secretary of State posts is only a sample not meant for submission, so the real filing happens online. The state's fee is $100, paid at the end of the online session. According to the state, a filing made online is posted in real time.

The statement covers these items, taken from section 7-90-803:

  • The partnership's true name, and an assumed entity name if it needs one
  • Its home jurisdiction
  • Its form, picked from a drop-down list (limited partnership or LLLP)
  • A physical principal office address
  • The registered agent's name and Colorado street address, plus confirmation that the agent consented
  • The date business in Colorado began or is expected to begin

The statute's list does not include the general partners' names. An individual signs for the filing under a perjury notice, and all text must be in English. The effective date may be delayed by up to 90 days.

Is a home-state certificate required?

No. The partnership does not have to produce a good standing certificate, proof of existence or a copy of its limited partnership certificate. The statute lists what the statement must say and the instructions walk through each field. A home-state document appears in neither.

That removes a step that slows filings elsewhere. There is nothing to order and no age limit to worry about. The preparation is mostly collecting facts: the exact name the partnership holds at home, where it was formed, the address of its principal office and who will serve as agent.

Names for limited partnerships

Section 7-90-601 requires a limited partnership name to include one of these: limited partnership, limited, company, L.P., LP, Ltd. or Co. A limited liability limited partnership may use those terms or limited liability limited partnership, L.L.L.P. or LLLP, among others. Every name must also differ from the names already on the state's record.

If the home name cannot be used because another entity holds it or because it lacks an ending, section 7-90-603 has the partnership adopt an assumed entity name for use in Colorado only. The state describes that as separate from a trade name or DBA. A name search comes first in the online process, which flags a conflict early.

The registered agent for a partnership without a Colorado office

A foreign limited partnership with authority has to have a registered agent in Colorado at every moment. Section 7-90-701 lists who qualifies, and its individual-agent rules apply from July 1, 2025.

  • An individual at least 18 years old whose primary home or usual place of business is in Colorado, and who either has a Colorado driver's license or ID card or gets residency verified by the state. Without a Colorado ID the person must request a passcode, and the state says review can take a few business days.
  • A Colorado business entity that is in good standing and has a usual place of business here.
  • A foreign entity already authorized in Colorado, in good standing, that maintains such a place of business.

The state's meaning of a usual place of business is a Colorado spot that is open during regular business hours and where a person authorized to receive process for the entity is typically present. P.O. boxes and commercial mailboxes cannot serve as the agent's street address. The agent must agree to the appointment, and the Secretary of State may not be the agent. A general partner who lives out of state generally cannot meet the test personally, which is why partnerships turn to a company agent.

After you are on the record

A foreign partnership holding Colorado authority is a reporting entity, which means one online periodic report every year at $25. Take authority that becomes effective in September. The report month is then September of the next year, and the first report is due on November 30 of that year. The window opens two months before the report month and closes two months after it. Skipping it leads to a $50 late penalty, then to noncompliant status and, if the report stays unfiled, delinquency. A delinquent partnership is shut out of Colorado courts for debt collection until it pays $100 for a Statement Curing Delinquency or files a withdrawal.

Statements of change cost $10 each, including a change of agent, and section 7-90-804 requires one whenever the filed statement stops being true. The Secretary of State does not deal with taxes, so tax registration goes through the Department of Revenue.

Closing out

A partnership that stops operating in Colorado files the Statement of Foreign Entity Withdrawal, an online filing that costs $10. Done before the next periodic report is due, it spares the partnership that report.

What an unregistered partnership risks

Section 7-90-802 sets out the consequences for operating without a filed statement.

While the statement is missing, the partnership cannot pursue a Colorado lawsuit aimed at collecting its debts, and a judge may hold any other action it brings until the court decides whether authority was required. Before a late statement will be accepted, the partnership must pay a back fee that the Secretary of State sets, with a statutory ceiling of $100 for each calendar year or partial year of unauthorized activity. A civil penalty of up to $5,000 may apply as well. The attorney general brings that action in the district court for the City and County of Denver, and the judge may bar the partnership from further Colorado business until the amounts and costs are paid.

The statute also says what does not happen. The partnership's acts stay valid, and it keeps its right to defend itself. The fee schedule lists no back-fee line, so the charge in practice is not published.

Mainstay and limited partnerships

Mainstay's checkout for foreign registrations stops at LLCs and corporations that operate for profit, so a limited partnership gets the registered agent. The agent costs $149 a year, flat, and the price does not move at renewal. The agent's Colorado address is what gets listed on the statement, and it becomes public. A summons or other papers that reach the agent are scanned and put in your account the day they come in, with no fee, and your first three government mailings of the year are scanned for free.

Should the partnership already have a different agent of record, Mainstay prepares the change-of-agent filing and passes the state's charge along at cost. The partnership, or its lawyer, files the Colorado statement. As a company, Mainstay can serve wherever the state lets an entity act as agent. It does not practice law. Details are on the Colorado registered agent page.

Frequently asked questions

Does a foreign limited partnership need a certificate of good standing in Colorado?

No. Nothing from the home state is attached: no good standing certificate, no proof of existence and no copy of the limited partnership's own certificate.

What is the Colorado fee for a foreign limited partnership?

The state's fee is $100, collected when the Statement of Foreign Entity Authority is filed. No separate partnership fee exists, and filing is online only because paper is not offered.

Do I register a limited partnership just because it owns Colorado property?

Under the statute, holding property without more does not count as transacting business. Registration depends on other activity, such as an office, employees or regular work in Colorado, and a lawyer can help on close calls.

Does Colorado have a different form for a limited liability limited partnership?

No. An LLLP uses the same statement as a limited partnership and picks its entity form from the drop-down list. Its name must include one of the endings in section 7-90-601, such as LLLP.

What happens if a limited partnership operates in Colorado without registering?

It loses access to Colorado courts for collecting debts until it files, owes a back fee that can reach $100 for each year, and may be fined up to $5,000. Contracts stay valid, and a defense in court remains open.

Who can be the registered agent of a foreign limited partnership?

An adult with a Colorado residence or workplace and a Colorado ID or verified residency, or an entity in good standing that has a Colorado place of business. A P.O. box cannot be the agent's street address.
