To start a business in Oklahoma, file Articles of Organization (LLC) or a Certificate of Incorporation with the Oklahoma Secretary of State, appoint a registered agent, get an EIN, and register with the Oklahoma Tax Commission through OkTAP for sales tax and withholding. As of October 2026, an Oklahoma LLC costs $100 to form, and it files a $25 annual certificate each year on its formation anniversary.
Oklahoma also became cheaper for corporations recently: the state franchise tax was repealed, and tax year 2023 was the last year domestic corporations had to file franchise tax returns.

How should you structure an Oklahoma business?
Oklahoma’s options:
| Structure | State filing | Liability | Yearly state filing |
|---|---|---|---|
| Sole proprietorship | Optional trade name ($25) | Personal | None with the SOS |
| General partnership | Optional fictitious name | Shared and personal | None with the SOS |
| LLC | Articles of Organization ($100) | Limited | $25 annual certificate |
| Corporation | Certificate of Incorporation ($50 minimum) | Limited | No franchise tax return since 2024 |
LLCs remain the most popular choice for small Oklahoma businesses: low cost, liability protection and simple governance. Corporations are now cheaper to keep than before, because the franchise tax repeal removed their annual franchise return, but they still carry more formalities such as directors, shareholder meetings and bylaws. See how to start an LLC in Oklahoma for the full filing walkthrough.
Pick a name that Oklahoma will accept
An Oklahoma LLC name must contain “limited liability company”, “limited company”, “LLC”, “L.L.C.”, “LC” or “L.C.”, according to the Form 0074 instructions. The name must also be distinguishable from existing corporations (including those that existed in the past three years), limited partnerships, LLCs, trade names and reserved names.
Checking takes a few minutes:
- Use the Secretary of State’s name availability search, and see our Oklahoma business name search guide for tips.
- Check domain and social handle availability with Namechk.
- Search the USPTO for federal trademarks.
Our business name generator helps if you need alternatives. You can reserve a name for 60 days for $10, and extend the reservation for another $10.
Trade names in Oklahoma
Oklahoma registers DBAs at the state level. File a Trade Name Report (Form 0021) with the Secretary of State for $25. Partnerships operating under a fictitious name file a Certificate of Partnership Fictitious Name instead.
Name a registered agent
Every Oklahoma LLC must keep a registered agent and registered office in the state. The registered office must be a physical Oklahoma street address, not a P.O. box, open during business hours. The agent can be an Oklahoma resident, a business entity in good standing in Oklahoma, or the LLC itself if it has a qualifying Oklahoma office. Changing the agent or office costs $25.
Owners who travel, live out of state or want privacy usually appoint a commercial agent. Mainstay Filing includes an Oklahoma registered agent for the first year with its formation package.
File your Articles of Organization
File online through the Secretary of State’s online filing system, available around the clock, or on paper with Form 0074. You will provide:
- The LLC name.
- The registered agent and registered office address.
- The term of existence (perpetual unless you state otherwise).
- The signature of an organizer.
- An email address, which matters because the Secretary of State sends annual certificate notices only by email.
The fee is $100, and card payments online add a 4% service charge. Oklahoma has no publication requirement. Corporations file a Certificate of Incorporation instead, with a fee of one-tenth of one percent of authorized capital and a $50 minimum.
After approval, sign an operating agreement for your LLC. Oklahoma does not collect it, but it governs ownership and management and is often requested by banks.
Get an EIN
Apply for a free Employer Identification Number on the IRS website. You need it for payroll, most bank accounts and your OkTAP registration.
Register with the Oklahoma Tax Commission
The Oklahoma Tax Commission handles business tax registration through OkTAP. Its New Business Center walks through the options. Common registrations include:
- Sales tax permit. Required for ongoing sales of tangible personal property. Oklahoma’s state sales tax rate is 4.5%, and cities and counties add their own rates, according to the Tax Commission.
- Withholding, once you have employees.
- Corporate income tax, for C corporations, filed on Form 513.
The franchise tax is gone. Under HB 1039X, tax year 2023 was the last year corporations filed franchise tax returns, per the Tax Commission’s business help center. LLCs were always exempt. Foreign corporations still pay a $100 annual registered agent fee on Form 200-R, due July 1.
Employer requirements
Oklahoma adopts the federal minimum wage of $7.25 per hour for employers with 10 or more full-time employees at any one location, or with annual gross sales over $100,000. Other employers have a $2.00 state minimum, according to the U.S. Department of Labor’s state table, though businesses covered by federal law must still pay $7.25.
Employers also:
- Register with the Oklahoma Employment Security Commission for unemployment tax through its new Employer Portal. The OESC lists a 1.5% rate for new employers.
- Report new hires within 20 days through the OESC new hire system.
- Carry workers’ compensation insurance for employees, as required under Oklahoma’s workers’ compensation law.
Licenses and permits
Oklahoma has no statewide general business license. Depending on what you do, you may need:
- State occupational licenses, such as construction trades, cosmetology, real estate or health care.
- Alcohol licenses through the Oklahoma ABLE Commission.
- City and county licenses, permits and zoning approvals in places such as Oklahoma City and Tulsa.
The Oklahoma SBDC offers free advising, and the Secretary of State’s starting a new business page collects useful links.
Banking and insurance
Open a business bank account with your filed Articles, EIN and operating agreement, and keep all business transactions in it. Insurance to compare includes general liability, professional liability, commercial auto and property coverage, along with workers’ compensation once you hire.
The Oklahoma LLC annual certificate
Every Oklahoma LLC files an annual certificate each year by the anniversary of its formation date. The fee is $25. According to the Secretary of State’s FAQ, there is a 60-day grace period, after which the LLC becomes inactive and falls out of good standing. Reinstating requires filing every past-due annual certificate.
Because reminders go only to the email address on record, keep that address current. A forgotten inbox is the most common way Oklahoma LLCs slip out of good standing.

FAQs
How much does it cost to start an LLC in Oklahoma?
As of October 2026, the Oklahoma Secretary of State charges $100 to file Articles of Organization for an LLC, plus a 4% service charge if you pay by card online. Each year after that, the LLC files a $25 annual certificate on its formation anniversary. A $10 name reservation and a $25 trade name report are optional.
When is the Oklahoma LLC annual certificate due?
The annual certificate is due each year on the anniversary of the LLC’s formation, and the fee is $25. Oklahoma allows a 60-day grace period. After that, the LLC becomes inactive and is no longer in good standing until it files all past-due certificates. Notices go only to the email address on record.
Does Oklahoma still have a franchise tax?
No. Oklahoma repealed its franchise tax, and tax year 2023 was the last year corporations had to file franchise tax returns. LLCs were always exempt. Foreign corporations registered in Oklahoma still pay a separate $100 annual registered agent fee to the Tax Commission on Form 200-R, due July 1.
How do I register a DBA in Oklahoma?
Oklahoma registers DBAs at the state level. File a Trade Name Report (Form 0021) with the Secretary of State for $25. Amendments, transfers and withdrawals also cost $25 each. Partnerships that do business under a fictitious name file a Certificate of Partnership Fictitious Name instead.
Do I need a business license in Oklahoma?
Oklahoma does not issue a general statewide business license. Most businesses need a sales tax permit from the Oklahoma Tax Commission if they sell goods, plus any occupational license for their field and the licenses or permits their city or county requires. Oklahoma City and Tulsa, for example, have their own licensing and zoning rules.
Can I be my own registered agent in Oklahoma?
Yes, if you are an Oklahoma resident with a physical street address in the state that is open during business hours. A P.O. box does not qualify. Your address becomes part of the public record, which is why many owners who travel, live elsewhere or value privacy hire a commercial registered agent.
What is the sales tax rate in Oklahoma?
Oklahoma’s state sales tax rate is 4.5%, and cities and counties add their own sales taxes, so combined rates vary by location. Businesses that make ongoing sales of tangible goods register for a sales tax permit with the Oklahoma Tax Commission through OkTAP before they start selling.
What is the minimum wage in Oklahoma?
Oklahoma follows the federal minimum wage of $7.25 per hour for employers with 10 or more full-time employees at any one location or more than $100,000 in annual gross sales. Other employers have a $2.00 state minimum, but any business covered by the federal Fair Labor Standards Act must still pay at least $7.25.
