How to Form an LLC in Oklahoma
Oklahoma charges $100 to form an LLC and $25 a year for an Annual Certificate due on the anniversary date. A registered agent is mandatory, a trade name is a $25 state filing, and the figure other guides get wrong is reinstatement: there is no reinstatement fee at all. The cost of coming back is only the delinquent annual certificates, $25 each.
Oklahoma at a glance
Filing fee: $100 for the Articles of Organization, filed with the Oklahoma Secretary of State. Recurring: An Annual Certificate for $25, due on the anniversary date of filing the articles, every year until the articles are canceled. There is no late fee, but missing it has the step by step consequences on the report page. Registered agent: required, with a physical address in Oklahoma. Every figure on this page was checked against the Oklahoma Secretary of State's, the Oklahoma Statutes', and the Oklahoma Tax Commission's official sites on November 8, 2026.
The Oklahoma filing steps
Check your name on the state's own search
Check availability in advance with the Secretary of State, by telephone at (405) 522-2520, online at sos.ok.gov, or in person, before you file. Under Title 18, section 2008, an Oklahoma LLC name shall contain the words "limited liability company" or "limited company" or the abbreviations "LLC", "LC", "L.L.C.", or "L.C.". The word "limited" may be abbreviated as "Ltd." and the word "company" may be abbreviated as "Co." The name must be such as to distinguish it upon the records of the Secretary of State from corporations, domestic and foreign, then existing or which have existed at any time during the preceding three years, from then existing domestic and foreign limited partnerships and limited liability companies, from trade names or fictitious names, and from names reserved with the Secretary of State. A search does not reserve the name. To hold one, file a name reservation for $10; it reserves the name for a period of 60 days under Title 18, section 2009. The Secretary of State also lists a Consent to Similar Name form at no fee.
Choose your registered agent
Oklahoma is not an optional agent state. Under Title 18, section 2010, every limited liability company must continuously maintain a registered agent and a registered office in Oklahoma, and the agent accepts service of process in the event of a lawsuit against the LLC. The registered agent must be the domestic limited liability company itself, an individual resident of Oklahoma, or a domestic or qualified foreign corporation, limited liability company, or limited partnership. Each registered agent shall maintain a business office identical with the registered office, open during regular business hours to accept service of process. The registered office address must be a street address; post office boxes are not acceptable. Changing or designating the registered agent, the registered office, or the principal office costs $25 on the change form filed under section 2010(B), and a registered agent resignation is also $25. The Secretary of State's fee schedule also lists an annual agent fee of $40, paid on July 1 each year, for the Secretary of State acting as the registered agent of an LLC; that $40 is due only when the Secretary of State serves as the agent, and it is not part of the base cost on this page.
File the Articles of Organization with the Secretary of State
File the Articles of Organization through the Secretary of State's Entity Filing system at sos.ok.gov, by mail, delivered in person, or online. The fee is $100 under Title 18, section 2055, whichever channel you use. Paying by credit card adds a four percent service charge on top under Title 18, section 1142; that charge is a payment charge, not part of the $100 fee, so this page does not call the fee $104. One or more persons may form an LLC, and the articles must be signed by at least one person, who may or may not be a member. Under Title 18, section 2005, the articles state the name of the LLC, the street address of its principal place of business, wherever located, with post office boxes not acceptable, the e-mail address of the primary contact for the registered business, the name and street address of its registered agent for service of process in Oklahoma, and the term of existence: perpetual, a set number of years, or a future effective expiration date. Perpetual means continuous. Current Secretary of State forms print two different mailing addresses, so confirm the current delivery address on sos.ok.gov before mailing a paper filing. Domestic professional LLCs cannot be submitted electronically; the professional LLC form carries the same $100 fee, in PDF only. In person filings may pay an additional $50 per document for Same Day Service under the Secretary of State's current Business Services page; older printed forms still state $25, a conflict flagged on the cost page.
Get an EIN from the IRS
Free, online, and takes minutes once your Oklahoma filing is approved. Never pay a service for this. See EIN for an LLC for the walkthrough and the one IRS rule (a real person as responsible party) that surprises people.
Write your operating agreement
Oklahoma defines the term at Title 18, section 2001(20): an operating agreement, regardless of whether referred to as an operating agreement and whether oral, in a record, implied, or in any combination thereof, means any agreement of the members, including a sole member, as to the affairs of a limited liability company and the conduct of its business, including the agreement as amended or restated. The State of Oklahoma's Register Your Business page advises owners to develop and maintain a written operating agreement. That is guidance to owners, not a filing requirement. No operating agreement form, filing, or fee appears on the Secretary of State's Business Forms page or fee schedule. The agreement is an internal document; it is not filed with the Secretary of State and carries no state fee.
Open the business bank account and handle licenses
Bring your approved formation document and EIN letter. Then check your city and county for a general business license and your industry for state permits. Oklahoma issues no single statewide general business license through the Secretary of State. Licensing is industry specific, through state agencies and boards, or local, through your city or county. The near universal state level step is tax registration with the Oklahoma Tax Commission for the taxes your activity triggers. Check your industry and your city before you budget, because those offices, not the Secretary of State, set those charges.
Filing details that trip people up
- No publication requirement to form. No publication step appears in Title 18, sections 2004 to 2005, or anywhere in the Secretary of State's filing procedures and instructions for the Articles of Organization. Oklahoma charges no publication fee and requires no newspaper notice to form an LLC.
- Foreign LLCs pay $300, and the home-state certificate is required, dated within 60 days. An out-of-state LLC files an Application for Registration of a Foreign Limited Liability Company for $300 under Title 18, section 2055, before transacting business in Oklahoma. Attach a certificate from the certifying officer of the home jurisdiction attesting to the LLC's organization and good standing, most commonly called a Certificate of Good Standing, Certificate of Existence, or Certificate of Fact. That certificate must be dated within the last 60 days. A foreign LLC also files the same $25 Annual Certificate, due on the anniversary of its registration, and withdraws for $100.
- A trade name is a $25 report filed with the Secretary of State, and the state materials state no term for it. A business entity doing business in Oklahoma under a name other than its legal name files a Trade Name Report with the Secretary of State under Title 18, section 1140, for $25. An amended report, a transfer, and a withdrawal of a trade name report are each $25 as well. No term, expiration date, or renewal filing for a trade name appears in section 1140, the report form, or the Secretary of State's forms and fee pages, and the State of Oklahoma's Register Your Business page states that no annual fee or tax is required for a trade name registration. This page publishes no DBA duration, because no primary source states one. Our DBA guide covers the details.
- Closing takes one filing, the Articles of Dissolution, for $50. The Articles of Dissolution are filed under Title 18, section 2041, signed by a manager, stating the name of the LLC, the date of filing of its articles of organization, the reason for filing, any future effective date, and other information, if any. There is no second termination filing and no second fee. No tax clearance field, Tax Commission sign-off, or clearance attachment appears on the dissolution form, and no tax clearance filing for LLC dissolution appears on the Secretary of State's fee schedule or Business Forms page. That is stated as an omission in the state's own materials, as the research directs; closing tax accounts with the Oklahoma Tax Commission is a distinct step the Secretary of State materials do not address.
- Reinstatement itself costs nothing. The $50 figure in other guides is the dissolution fee. The Secretary of State's Business Forms page lists Reinstatement at no fee for domestic and foreign LLCs, and the Application for Reinstatement, filed under Title 18, section 2055.3, states that there is no additional fee due for the application itself. What reinstatement costs is the filings that were missed: $25 for each delinquent annual certificate, plus any delinquent $40 registered agent fees. Three missed years cost $75 in certificates, not $75 plus a reinstatement fee.
After your Oklahoma LLC is approved
Get the EIN, open the business bank account, and register with the Oklahoma Tax Commission for the tax accounts your activity triggers. Then set one recurring reminder: the Annual Certificate, $25, due on the anniversary date of filing the articles every year until the articles are canceled. The Secretary of State sends notice at least 60 days before the anniversary date, and only to the LLC's last known electronic mail address of record, so keep that e-mail address current. Keep the registered agent and registered office current as well, and file the $25 change form whenever the agent, the office, or the principal office changes. If the business will trade under a different name, budget the $25 Trade Name Report.

Oklahoma LLC questions
How much does reinstatement cost for an Oklahoma LLC?
There is no reinstatement fee. The Secretary of State lists Reinstatement at no fee, and the Application for Reinstatement under Title 18, section 2055.3 states that no additional fee is due for the application itself. You pay only what was missed: $25 for each delinquent annual certificate, plus any delinquent $40 registered agent fees. The $50 reinstatement figure in other guides is a confusion with the $50 Articles of Dissolution fee. See the Oklahoma compliance page.
What happens if I miss the Oklahoma Annual Certificate?
Nothing is charged as a late fee, and the certificate costs the same $25 whenever it is filed. At 60 days after the due date the LLC ceases to be in good standing, the Secretary of State will not accept most filings or issue a certificate of good standing until it is reinstated, and the LLC may not maintain an action in an Oklahoma court until reinstated. If the certificate and fee stay unpaid for three years, the articles of organization are deemed canceled, effective on the third anniversary of the due date.
Does an Oklahoma LLC need a registered agent?
Yes. Under Title 18, section 2010, every LLC must continuously maintain a registered agent and a registered office in Oklahoma. The agent may be the LLC itself, an individual resident of Oklahoma, or a domestic or qualified foreign corporation, limited liability company, or limited partnership. Changing the agent or office costs $25.
Does an Oklahoma LLC file a BOI report?
No. US-formed companies are exempt under the federal final rule of August 14, 2026. See the BOI tracker.
