How to Form an LLC in Oklahoma

Forming an Oklahoma LLC

Oklahoma keys its recurring LLC filing to an exact calendar date. Under 18 O.S. § 2055.2(B) the annual certificate falls due "on the anniversary date of filing the articles of organization," and § 2055.2(C) has the Secretary of State give notice at least 60 days ahead to the company's last known electronic mail address of record. Form 0074 is blunt about the single channel: that notice "will ONLY be sent" to that address. That is why the formation form makes an e-mail address a required field.

Missing the date carries no fee. Neither § 2055, the complete list of LLC fees the Secretary of State collects, nor its published fee schedule contains a late or penalty charge. The consequences are procedural: under § 2055.2(D) a company that fails to file and pay within 60 days after the date due ceases to be in good standing, and § 2055.2(F) bars it from maintaining any action, suit or proceeding in an Oklahoma court until it is reinstated. The articles themselves must state a term of existence, they name no members or managers, and for a professional LLC they cannot be filed electronically at all.

Filing the articles of organization

The Oklahoma Limited Liability Company Act, 18 O.S. § 2000 et seq., was last generally amended by Laws 2024, c. 121, effective November 1, 2024. Under § 2004(A) a company is formed "upon the filing of executed articles of organization with the Office of the Secretary of State," and § 2004(B)(2) makes that filing conclusive evidence of formation. The state publishes the document as SOS Form 0074, and § 2007(B) treats the company as formed at the time of filing unless the articles set a future effective date no later than 90 days after.

What the articles must contain

Section 2005(A) lists three items: the company name; the term of existence, which may be perpetual; and the street address of its principal place of business, wherever located, together with the name and street address of its registered agent, identical to its registered office in this state. Form 0074 marks both address fields "(P.O. BOXES ARE NOT ACCEPTABLE)" and takes a term stated as "either perpetual, a set number of years, or a future effective expiration date." Members and managers are not on the statutory list, though § 2005(C) lets the articles set forth any other matters the members determine to include. Under § 2006(A)(1) the articles must be signed by at least one person, who need not be a member, and § 2006(C) makes that signature an affirmation under the penalties of perjury.

Fees and payment

Section 2055 sets the fee for the original articles at $100.00, the fee schedule carries the same figure, and the amount does not move with the filing method. Credit cards are taken in person and online, but Form 0074 warns that "there will be a four percent (4%) service charge added for the use of a credit card," a convenience fee authorized by § 1142(G)(2). A check or money order avoids it. Amendment costs $100 on the same schedule, and articles of dissolution $50.

What the state publishes about speed

Articles may be presented in person or delivered by mail, faxed or submitted online through the Entity Filing page, which the Business Entity FAQ says can be done "24 hours a day, 7 days a week." Paper goes to the Business Filing Department, 421 N.W. 13th, Suite 210, Oklahoma City OK 73103.

No Secretary of State page states a turnaround for a business entity filing. The Business Services page says only that filings delivered in person "must be presented before 4:30 pm CT to be processed" and that all other documents are processed in the order received. That page sets Same Day Service at "$50.00 for each document" presented in person, and the complete fee schedule carries no expedited, priority or 24 hour row. The Oklahoma Department of Commerce does publish a figure for online business registration: "Registering your business takes about 15 minutes and costs $100 plus a service fee."

Professional limited liability companies

Domestic professional entities formed under Title 18, Chapter 18, Sections 801 to 819 "CANNOT be submitted electronically," the Entity Filing page states. A professional LLC files SOS Form 0010 on paper for the same $100 fee, attaching a certificate from the regulating board that each owner and manager is duly licensed, and its name carries "PROFESSIONAL" or an abbreviation such as "PLLC" under Title 18, Section 807.

Naming an Oklahoma LLC

Section 2008(A) requires the name to contain "limited liability company" or "limited company," or the abbreviations LLC, LC, L.L.C. or L.C. Section 2008(C) then applies a three year lookback: the name may not be the same as or indistinguishable from the name of an LLC, corporation, partnership or registered series on the Secretary of State's records that is in good standing or registered now, or that was at any time during the preceding three years, or from a trade name, fictitious name or reserved name.

The Business Entities Search gives a free preliminary check on a particular name. Filing the articles does not stop anyone else from using the name. By the Business Entity FAQ's account, the filing only prevents the Secretary of State from later filing a formation certificate for a name that is the same as or indistinguishable to the company's. SOS Form 0034 reserves a name for the exclusive use of the applicant for 60 days for $10, under § 2009(B) and § 2055(7), and an extension or renewal is a separate $10 filing. The state attaches a caution: "a name reservation is not a business registration, its purpose is to only reserve the business name."

Registered agent and registered office

Section 2010(A)(1) requires every domestic LLC to "continuously maintain" an Oklahoma registered office, which need not be its principal place of business, and a registered agent whose office is identical to it. The company itself may serve, as may an individual resident of Oklahoma or a domestic or qualified foreign corporation, LLC or partnership. Each agent "shall maintain a business office identical with the registered office which is open during regular business hours to accept service of process," at a physical Oklahoma address where the agent can be personally served. Form 0074 rules out P.O. boxes there. The Oklahoma registered agent page covers the role in more detail.

Where no agent has been appointed, § 2055(13) charges $40.00 each July 1 for the Secretary of State acting as registered agent, and § 2055.1 puts a company that misses that payment under the same provisions as a missed annual certificate. Changing the agent, the registered office or the principal office is a $25 filing on SOS Form 0075, signed by a manager of the company; an agent's resignation is also $25.

Operating agreement

Section 2001(20) reaches an agreement of the members, including a sole member, as to the affairs of the company and the conduct of its business, "whether oral, in a record, implied or in any combination thereof." Nothing about it is filed: it is not among the contents § 2005(A) requires, and the fee schedule has no row for it. Section 2012.2(B) binds the company to its operating agreement "regardless of whether it executes the operating agreement," while § 2012.2(A) makes the Act govern where the agreement is silent and bars it from varying the duties the Act imposes specifically. A one member agreement is enforceable under § 2012.2(C), and § 2012.2(E) lets members holding a majority of the membership interest entitled to vote amend an agreement that says nothing about amendment. See the operating agreement guide.

The annual certificate

Section 2055.2(A) requires every domestic LLC and every foreign LLC registered in Oklahoma to file a certificate each year confirming it is an active business, with its principal place of business address, and to pay $25.00. SOS-FORM-0097 collects those items plus the primary contact's e-mail address, which is "REQUIRED in order to receive future annual certificate notices," and is signed by a member or manager. It may also go through the Online Business Filing System.

When the certificate is missed

Sixty days past the due date, § 2055.2(D) ends the company's good standing. Section 2055.2(E) then stops the Secretary of State from accepting any certificate or articles for filing and from issuing a certificate of good standing, excepting only a reinstatement application and a registered agent's resignation with no successor. Under § 2055.2(F) the company may not maintain any action, suit or proceeding in any court in Oklahoma until it is reinstated. Three years of non-payment cancels the company on paper: § 2012.1(B) deems the articles of organization canceled, effective on the third anniversary of the due date.

Reinstatement under § 2055.3(A) takes every delinquent annual certificate and all delinquent fees, filed with an application for reinstatement, SOS Form 0145, which carries "no additional fee due for the Application for Reinstatement form itself." Section 2055.3(B) makes reinstatement relate back as if the company had never ceased to be in good standing.

Oklahoma taxes that reach an LLC

The franchise tax no longer reaches current years: 68 O.S. § 1203 and § 1204 levy it only "For tax year 2023 and previous tax years."

Oklahoma's individual income tax is graduated, and the 4% corporate income tax at 68 O.S. § 2355(H) reaches an LLC only where the LLC is taxed as a corporation. For tax year 2026, § 2355(D) applies 0% to the first $3,750 of taxable income for a single filer or a married person filing separately, 2.5% to the next $1,150, 3.5% to the next $2,300 and 4.5% to the remainder. Those first three bands are $7,500, $2,300 and $4,600 for married persons filing jointly, surviving spouses and heads of household. Oklahoma LLC taxes goes through the returns.

An LLC making taxable sales needs a sales tax permit. The state rate is 4.5% under § 1354(A), and § 1364(A) requires the permit to be secured from the Oklahoma Tax Commission every three years for a $20.00 fee, which the Department of Commerce describes as "$20 plus a handling fee" through the OTC application portal.

One yearly Oklahoma obligation runs to the county rather than to a state agency. Form 901 reports a business's taxable tangible assets as of January 1 to the county assessor, and the 2026 form carries its deadline on its face: "Filing Date: January 1 - Delinquent Penalties after March 15." Under 68 O.S. § 2836(C) a late return adds 10% of assessed value after March 15 and 20% after April 15.

State licenses and permits

The Department of Commerce frames state licensing by industry and names activities that do not need a state license: repair and installation services, cleaning services, business services including general consulting and bookkeeping, and lawn services. It qualifies the list at once, since "licenses for these activities may still be required by counties and municipalities." A municipality may require licensing with the city, and the same agency warns that entity registration is "completely different" from obtaining the licenses and permits needed to operate.

Getting an EIN

An EIN comes from the Internal Revenue Service rather than from any Oklahoma agency, and the state sequences it before the sales tax permit, whose application asks for the Secretary of State filing number and the EIN obtained previously. The EIN guide covers how to apply.

Frequently asked questions

How much does it cost to form an LLC in Oklahoma?

18 O.S. § 2055 sets the fee for filing original articles of organization at $100.00, and the Secretary of State's fee schedule carries the same amount for mail, in person and online filings. Paying by credit card adds a 4% service charge, which a check, cashier's check or money order avoids.

When is the Oklahoma annual certificate due?

18 O.S. § 2055.2(B) makes the annual certificate due on the anniversary date of filing the articles of organization, each year, and the fee is $25.00. The Secretary of State sends notice at least 60 days ahead to the company's last known electronic mail address of record, and to no other address.

What happens if an Oklahoma LLC misses the annual certificate?

There is no monetary late fee in 18 O.S. § 2055 or on the Secretary of State's fee schedule. Sixty days after the due date the company ceases to be in good standing under § 2055.2(D), the Secretary of State stops accepting its other filings, and it may not maintain an action in an Oklahoma court until it is reinstated. After three years the articles are deemed canceled.

Does Oklahoma publish a processing time for LLC filings?

The Secretary of State's Business Services, Fee Schedule, Business Forms, Entity Filing and Business Entity FAQ pages state no turnaround for a business entity filing. The Business Services page says documents are processed in the order received, that in person filings must be presented before 4:30 pm CT, and that Same Day Service costs $50.00 for each document.

Does Oklahoma still charge LLCs a franchise tax?

68 O.S. § 1203 and § 1204 levy the franchise or excise tax only for tax year 2023 and previous tax years.

Can a professional LLC be formed online in Oklahoma?

No. The Secretary of State's Entity Filing page states that domestic professional entities formed under Title 18, Chapter 18, Sections 801 to 819 cannot be submitted electronically. A professional LLC files SOS Form 0010 on paper with a certificate from the regulating board of the profession attached.
