How to Start a Corporation in Oklahoma: Certificate of Incorporation Fee Is 0.1% of Authorized Capital
If you want to incorporate in Oklahoma, the state filing fee is not a flat number. The Oklahoma Secretary of State charges one-tenth of one percent (0.1%) of your authorized capital stock for the Certificate of Incorporation, with a $50 minimum. Because the fee tracks the shares you authorize, two corporations filing the same paperwork can pay very different amounts. This guide covers how to start a corporation in Oklahoma step by step, what each step costs, and the recurring filings and taxes to track after you file.
This is informational content, not legal or tax advice. Entity choice, share structure and tax elections have real consequences, so talk with a qualified Oklahoma attorney and a certified public accountant (CPA) before you file.
What the Certificate of Incorporation Fee Actually Is
A for-profit corporation is formed by filing a Certificate of Incorporation with the Oklahoma Secretary of State, Business Filing Department. The fee is based on the authorized capital stock listed in the certificate, which is the maximum number of shares the corporation may issue. Note that the fee uses what you authorize, not what you issue later. For par-value shares, the fee uses the par value. For no-par shares, the Secretary of State counts each share as $50 of capital.
- For-profit corporations: 0.1% of authorized capital stock, $50 minimum
- Nonprofit corporations: $25
- No-par shares: each share counts as $50 of capital
- Professional and benefit corporations: $50 minimum
| Scenario | Authorized capital | Certificate fee |
|---|---|---|
| 10,000 no-par shares | $500,000 (10,000 × $50) | $500 |
| 10,000 shares at $0.001 par | $10 | $50 (minimum applies) |
The no-par structure costs ten times as much as the same share count at $0.001 par. Before you choose a share count, decide how many authorized shares you actually need now and in the near future, such as shares for investors or employee equity. Raising the authorization later requires an amendment, which costs $50.
Step-by-Step: How to Start a Corporation in Oklahoma
Step 1: Check and reserve your corporate name
Your name must include one of these words: association, company, corporation, club, foundation, fund, incorporated, institute, society, union, syndicate or limited, or an accepted abbreviation of one of them (18 O.S. 1006(A)(1)). It must also be distinguishable from entity, trade and reserved names on file. Search the state database on the Secretary of State business search before you commit to a name. If you need time to finish your paperwork, reserve the name for $10 for 60 days through the name availability page.
Step 2: Set authorized shares and par value
Decide how many shares the corporation may issue and whether they carry a par value. Par value is a stated dollar amount per share. A low par value keeps the fee at the $50 minimum for a small share count, while no-par shares are counted at $50 each. Choose a number that covers your foreseeable needs, not a number that looks impressive on paper.
Step 3: Appoint a registered agent and office
Every corporation must keep a registered agent at a physical Oklahoma street address. A PO box does not qualify, and the office must be open during business hours to accept service of process (18 O.S. 1022). The agent can be the corporation itself, an individual Oklahoma resident, or a domestic or qualified foreign corporation, LLC or limited partnership in good standing. Changing the agent or office costs $25.
Step 4: Name at least one director
Oklahoma requires one or more directors, and each must be a natural person, meaning an individual rather than another entity (18 O.S. 1027(B)). Directors manage the corporation, so choose people who will be available to act for it.
Step 5: File the Certificate of Incorporation
The certificate must state the corporate name, registered office and agent, purpose, authorized shares, and whether those shares have a par value or are no-par. File through the Business Services section of the Secretary of State website, where the online option is labeled File Online. Card payments add 4 percent to the total.
The Secretary of State publishes no processing time guarantee for filings. Documents are handled in the order received, and in-person filings must arrive before 4:30 p.m. Central. Online turnaround is not published, so call the Business Filing office at 405-522-2520 before you file if timing matters. Same-day service costs $50 per document and is available only for documents presented in person at the Secretary of State office. Confirm that it applies to your filing.
Step 6: Get an EIN and register for state taxes
Apply for a federal Employer Identification Number (EIN) with the IRS before you open a bank account or hire anyone. If the corporation will collect sales tax or withhold tax from employees, register with the Oklahoma Tax Commission (OTC) through OkTAP. If you sell taxable goods, the sales tax permit costs $20 for three years.
Step 7: Complete the first organizational steps
Adopt bylaws, hold the first board meeting, issue shares as your board approves, and keep the minutes and stock records in one place. These steps are not filed with the state, but they support the corporation's separate existence if it is ever challenged. Have your attorney draft these documents.
Ongoing Filings: What You Owe After You Incorporate
Oklahoma's recurring requirements for corporations are lighter than those in many states, but they are not zero. Check each item below.
- Annual report: The Secretary of State forms list shows no annual certificate for domestic for-profit corporations. The fee list does carry a general annual certificate line under 18 O.S. 1142, with a $10 minimum, which is used for foreign corporations. Check with the Secretary of State to confirm that nothing is due on your domestic corporation.
- Franchise tax: Oklahoma's franchise tax ended with tax year 2023 under HB 1039. Nothing is owed for tax year 2024 and later.
- Corporate income tax: Corporations pay a flat 4% corporate income tax for tax years beginning after December 31, 2021. Ask your CPA how estimated payments and filing deadlines apply to you.
- Foreign corporations: A foreign corporation pays a $100 annual registered agent fee to the OTC on Form 200-R, due July 1.
- Suspension: A corporation suspended for tax years 2023 and earlier stays suspended until it is reinstated. The OTC charges a one-time $150 reinstatement fee. Confirm the current amount with the OTC.
Other filings have set fees: $50 for an amended or restated certificate, dissolution or revival; $100 for a merger; and $20 for a certificate of good standing. Banks and lenders often ask for a good standing certificate, so order one before you need it.
Owner-Employees and Workers' Compensation
A stockholder-employee who owns 10 percent or more of the corporation falls outside Oklahoma workers' compensation coverage unless that person elects coverage. Confirm how this exclusion works with your insurance carrier before you rely on it, because it determines who on your payroll is covered.
State and Local Licenses
Oklahoma has no general state business license. Your Secretary of State filing and any OTC registration are the core state requirements. Beyond that, licenses depend on what the corporation does and where it operates.
- State: Regulated trades and professions are licensed by state boards and agencies. Examples include the Construction Industries Board for contractors, the Cosmetology and Barbering Board for cosmetology and barbering, and the ABLE Commission for alcohol. Confirm requirements with the agency before you open.
- Cities: Oklahoma City and Tulsa issue no general city business license. They license specific activities such as contractors, alcohol, mobile food and short-term rentals. A minority of cities charge a general or occupational license, including Bartlesville, Yukon, Sapulpa, Bixby, Tahlequah and Mustang. Each city sets its own list, so check the city where you operate.
- Counties: Counties issue no business licenses. Only Oklahoma County and Tulsa County run zoning and building permits in unincorporated areas.
Sales Tax Basics
The state sales tax rate is 4.5%. Cities and counties add their own sales taxes, which the OTC collects with the state tax on one return, so combined rates run from about 8.25% to above 10%. Since August 29, 2024, the state rate does not apply to most food and food ingredients, but local taxes still do. Register through the OkTAP business registration page, and confirm the local rate for your address with the Oklahoma Tax Commission before you set prices.
Trade Names and DBAs
If the corporation operates under a name other than its registered corporate name, file a Trade Name Report with the Secretary of State. It is a state filing, not a county filing, and no newspaper publication is required. The fee is $25 to file, amend, transfer or withdraw, with no annual fee. Details are on the Secretary of State filing page.

Before You File
Incorporating is more than one filing. Share structure, bylaws, tax elections and shareholder agreements all affect how the corporation operates and what it owes. Have an Oklahoma attorney review the Certificate of Incorporation and bylaws, and have a CPA review tax elections and the 4% corporate income tax. This article is informational only, not legal or tax advice. Confirm current fees with the Secretary of State and the Oklahoma Tax Commission before you file.
