Oklahoma LLC vs Corporation: $100 vs 0.1% Filing Fee, $25 Annual Certificate vs None on the Forms List
If you are deciding between an LLC and a corporation, the Oklahoma numbers come first. An LLC pays a flat $100 to file Articles of Organization. A corporation pays 0.1 percent of its authorized capital stock, with a $50 minimum. After formation, an LLC files a $25 annual certificate every year, while the Secretary of State's forms list shows no annual certificate for domestic for-profit corporations. Those are the headline differences in any Oklahoma LLC vs corporation decision. This guide covers the fees, the recurring filings, the tax treatment, and the owner rules that come after the filing fee.

Side-by-side comparison
| Item | LLC | Corporation |
|---|---|---|
| Formation document | Articles of Organization | Certificate of Incorporation |
| Formation fee | $100 | 0.1% of authorized capital stock, $50 minimum (nonprofit $25) |
| Annual state filing | LLC Annual Certificate, $25 | None on the SOS forms list (confirm with the Secretary of State) |
| Annual filing due | Formation anniversary, 60-day grace period | Not applicable on the forms list |
| Franchise tax | None for tax year 2024 and later | None for tax year 2024 and later |
| Income tax | Passes through to owners at individual rates | 4% flat corporate rate |
| Foreign registration | $300 flat | $300 minimum, Secretary of State as statutory agent, plus $100 annual OTC fee |
| Name reservation | $10 for 60 days | $10 for 60 days |
The formation fee: $100 flat vs 0.1% of capital
The LLC fee is simple. Articles of Organization cost $100. The Secretary of State publishes no processing-time guarantee and handles documents in the order received, so if you need a filing by a specific date, call the Business Filing office at 405-522-2520 to check current turnaround.
The corporation fee depends on how you set up your stock. The fee is one-tenth of one percent of authorized capital stock, with a $50 minimum. Shares without par value count as $50 each for this calculation, which creates a large difference:
- 10,000 no-par shares: each counts as $50, so the authorized capital is $500,000 and the fee is $500.
- 10,000 shares at $0.001 par: the capital is $10, so the fee is the $50 minimum.
Nonprofit corporations pay $25. Par value is a legal and accounting decision, not only a fee decision, so talk with an attorney before you set it.
Recurring filings: the $25 LLC certificate vs the corporate forms list
LLC Annual Certificate
An Oklahoma LLC files the LLC Annual Certificate for $25. It is due on the anniversary of the Articles of Organization filing, and the state allows a 60-day grace period. The statute sets no late fee. An LLC that misses the 60 days stops being in good standing. Reinstatement has no fee of its own, but you must file every delinquent annual certificate first, so a missed year costs you more than a late fine would. Put the anniversary on your calendar the day you file.
Corporations
The Secretary of State's forms list shows no annual certificate for domestic for-profit corporations, and Title 18 of the Oklahoma Statutes shows none for them either. Do not read that as 'nothing is owed.' Confirm with the Secretary of State before you assume you have no annual obligation. The fee list also carries a generic 'Annual Certificates' line under 18 O.S. 1142, with a $10 minimum, which is used for foreign corporations. Foreign corporations also pay a $100 annual registered agent fee to the Oklahoma Tax Commission by July 1.
Franchise tax: none for either entity
Oklahoma has no franchise tax for tax year 2024 and later. The franchise tax was repealed after tax year 2023, and LLCs were never subject to it. Neither entity pays a franchise tax. The recurring state filing cost for an LLC is the $25 annual certificate, subject to the agent fee note later in this guide. For a corporation, the recurring state cost is income tax, plus any foreign registration or agent fees that apply.
How each entity is taxed
The filing fees are the small part of the decision. Income tax usually matters more.
- LLC (default pass-through): profit flows to the owners and is taxed on their personal returns at Oklahoma individual rates. For tax year 2026 the top individual rate is 4.5 percent. Single filers pay 0 percent on the first $3,750, then 2.5, 3.5 and 4.5 percent. The rates can fall further if a revenue trigger is certified. Check the Oklahoma Tax Commission for current bands before you plan around them.
- Corporation (C corporation): the corporation pays Oklahoma corporate income tax at a 4 percent flat rate for tax years beginning after December 31, 2021. Owners may be taxed again when profits are paid to them as dividends.
Federal tax elections, such as electing corporate or S corporation treatment, change the picture. Ask a CPA before you make one.
Owner and management rules
A corporation's board of directors must be one or more natural persons, meaning individuals, not another company. An LLC is run under its operating agreement, which you draft to fit how the owners want to make decisions. Choose the structure with those governance needs in mind.
Workers' compensation is another difference. LLC members and 10 percent stockholder-employees are outside Oklahoma workers' compensation coverage unless they elect coverage. If owners also work in the business, confirm with your insurance agent or attorney how to handle this before you hire anyone.
Foreign registration if you operate from another state
If your entity was formed in another state and does business in Oklahoma, it must register as a foreign entity. An LLC pays a $300 flat fee. A corporation pays a $300 minimum, uses the Secretary of State as its statutory agent, and pays the $100 annual OTC fee on top. Confirm current amounts with the Secretary of State before you file.
Registered agent, name rules and trade names
Both entities need 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 legal papers. The agent can be the entity 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. If the Secretary of State acts as your agent, check with that office whether its $40 annual agent fee applies to your LLC.
An LLC name must contain limited liability company, limited company, LLC, LC, L.L.C. or L.C. ('limited' may be 'Ltd.' and 'company' may be 'Co.'). The name must be distinguishable from other entity, trade and reserved names on file, current or within the last 3 years. Corporate naming rules are set on the Secretary of State site, so confirm them there before you file. You can reserve either name for $10 for 60 days at the Secretary of State name availability page.
If you operate under a name other than your entity name, file a Trade Name Report with the Secretary of State for $25 at the Secretary of State filing page. It is a state filing, not a county filing, and no newspaper publication is required. General partnerships file a Certificate of Partnership Fictitious Name for $50.
Licenses, permits and sales tax
Oklahoma has no general state business license. Forming the entity with the Secretary of State is the core filing. After that:
- Register with the Oklahoma Tax Commission through OkTAP if you collect sales tax or withhold tax from employees.
- Get the licenses your activity requires from the state, your city or your county.
The state sales tax rate is 4.5 percent. The Oklahoma Tax Commission collects city and county sales tax on the same return, so combined rates run from about 8.25 percent to above 10 percent depending on location. A sales tax permit costs $20 for three years. Since August 29, 2024, the state rate does not apply to most food and food ingredients, but local sales taxes still do.
Cities handle most local licensing, and the rules vary. Some cities charge a general or occupational license, including Bartlesville, Yukon, Sapulpa, Bixby, Tahlequah and Mustang. Oklahoma City, Tulsa and Lawton license only specific types of activity. Oklahoma City and Tulsa issue no general city business license. Cities separately license specific activities such as contractors, alcohol, mobile food vendors and short-term rentals, so check your city's website before you open.
Counties issue no business licenses. Only Oklahoma County and Tulsa County run zoning and building permits in unincorporated areas. Regulated trades and professions are licensed by state boards, so if your work requires a license, contact the board that oversees it.
Which structure fits your plans
An LLC usually suits owners who want a $100 formation cost, a single $25 yearly certificate, pass-through taxation and flexible internal rules. A corporation usually suits owners who expect to issue stock to outside investors, want a formal board, or plan to use C corporation taxation at 4 percent. Oklahoma also permits series LLCs, which can separate assets across business lines. That structure is more complex and needs professional setup.
