How to Start an LLC in Oklahoma (2025 Guide)

How to Form an LLC in Oklahoma in 5 Steps

In order to form your LLC in Oklahoma, there are certain steps you’ll need to complete:

1. Name Your Oklahoma LLC
2. Choose a Registered Agent
3. File the Articles of Organization
4. Create an Operating Agreement
5. Get an EIN

Step 1: Name Your Oklahoma LLC

Before you get started, you will need to pick a suitable name for your Oklahoma LLC. 

This will need to comply with all applicable naming requirements under Oklahoma law and be both succinct and memorable, as this will make it easily searchable by your potential clients.

1. Oklahoma LLC Naming Guidelines

• Your name must contain the words “limited liability company,” “limited company,” or a suitable abbreviation (e.g., LLC, LC, etc.). Note that the word “limited” may be abbreviated to “Ltd”, and the word “company” may be abbreviated to “Co.” 
• Your name must be distinguishable from the names of all other existing business entities that have been present in the records of the office of the Secretary of State for the last three years.
• Your name cannot contain words that could create a false implication of a government or state affiliation (e.g., State, FBI, etc.). 

For more information on these rules, see Oklahoma’s official business name guidelines.

2. Oklahoma Name Availability Search

To check whether your desired name has already been taken by another business entity in Oklahoma, you can perform a business entity search on the Secretary of State’s website. 

If you’re not going to start your LLC right away, it might be a good idea to consider reserving your name for up to 60 days. You can do this by filing a Name Reservation application and paying the $10 filing fee. 

For more information, you can have a look at our Oklahoma LLC Name Search guide.

3. Finding the Right Domain

You should check online to see if your business name is available as a web domain. Even if you don’t plan to make a business website right away, this is an extremely important step as it will prevent others from acquiring it, potentially saving you both time and money in the long term.

Once you have verified your name is available, you may now select a professional service to complete the LLC formation process for you.

Step 2: Choose a Registered Agent in Oklahoma

After you find the right name for your LLC, you will need to nominate an Oklahoma registered agent. This is a necessary step in your Articles of Organization (i.e., the document used to file and register your LLC with the Secretary of State).

What is a registered agent?

A registered agent is an individual or business entity that will be responsible for receiving service of process — as well as other important government correspondence — on behalf of your LLC.

Who can be a registered agent?

A registered agent can be a resident of Oklahoma or a business entity (i.e., an LLC, limited partnership, corporation) that is authorized to transact business within the state. You can choose to elect an individual within the company (e.g., yourself, etc.), use an attorney (not recommended due to the high cost), or go with a registered agent service.

Step 3: File the Oklahoma LLC Articles of Organization

To register your Oklahoma LLC, you will need to file the Articles of Organization with the Oklahoma Secretary of State. You can do this online, by mail, or in person. 

Before filing, make sure you have completed your Articles of Organization correctly. You will need the following information to get started:

• Your LLC’s name and principal place of business (P.O. boxes are not acceptable)
• The email address of the primary contact of your LLC
• The name and street address of your registered agent 
• Your LLC’s term of existence (perpetual, a set number of years, etc.).
• Your signature, full name, and contact information

Step 4: Create an Oklahoma LLC Operating Agreement

An operating agreement is not required in Oklahoma, but it’s a good practice to have one.

What is an operating agreement? An operating agreement is a legal document outlining the ownership and operating procedures of an LLC.

Why are operating agreements important? A comprehensive operating agreement ensures that all business owners are on the same page and reduces the risk of future conflict.

Step 5: Get an EIN for Your Oklahoma LLC

You can get an Employer Identification Number (EIN) from the IRS for free. It is used to identify a business entity and keep track of a business’s tax reporting. It is essentially a Social Security number (SSN) for the company.

Why do I need an EIN? An EIN number is required for the following:

• To open a business bank account for the company
• For federal and state tax purposes
• To hire employees for the company

Where do I get an EIN? An EIN is obtained from the IRS (free of charge) by the business owner after forming the company. This can be done online or by mail.

Important Next Steps to Protect Your Oklahoma LLC

After you’ve formed your LLC, you’ll need to complete several key steps in order to:

• Separate your personal and business assets
• Stay compliant with state and federal laws

1. Get a Business Bank Account and Credit Card

Getting a dedicated business bank account is an essential part of operating legitimately as it keeps your personal and business assets separate, and therefore helps shield your personal limited liability. 

Skipping this step can often lead to:

• Courts determining that you haven’t been treating your LLC as a separate entity
• Your “corporate veil” being pierced, meaning that you will no longer benefit from limited liability in law. 

Recommended: Have a look at our Best Business Bank Accounts for LLCs in 2025 review. 

You can also choose to acquire a corporate credit card if you’re interested in building your credit and potentially raising capital down the line. 

2. Check If You Need an Oklahoma Business License

Oklahoma does not require LLCs to hold a “general” business license in order to operate. 

Even so, you should know that business licensing is regulated at a local, state, and federal level, so your licensing needs will ultimately depend on your exact location and industry:

• Local Licenses: You’ll need to check with your city or county clerk’s office to identify any local licensing requirements, such as zoning permits or health department approvals you’ll need. 
• State-Level Licenses: You can contact Business Customer Services at the Oklahoma Department of Commerce to find out whether a license, permit, or other filing is required for your specific type of business activity. Alternatively, you can also visit the Department’s Starting a Business page to see a breakdown of licensing and operating requirements by industry.
• Federal Licenses: While most Oklahoma LLCs will not be subject to federal regulation, those involved in heavily regulated industries (such as agriculture, alcohol, and firearms) will. You can have a look at this Small Business Administration article for the relevant federal agency you’ll need to contact.

A few questions to ask yourself when deciding whether you need a license include:

• Will you sell, lease, or rent taxable goods or services? If so, you’ll need to obtain a Sales Tax Permit from the Oklahoma Tax Commission. You can find more information on this on our Oklahoma Sales Tax guide. 
• Will you work as a licensed professional? If your LLC will focus on regulated fields — such as medicine, law, insurance, or real estate — you’ll need to ensure that you or a member of your LLC is appropriately licensed.
• Will your LLC’s activities negatively impact the environment? If so, you might need to obtain a business license or permit from the Oklahoma Department of Environmental Quality.

3. Understand Your Oklahoma LLC Tax Obligations

Oklahoma LLCs are not all taxed in the same way; this is because LLCs are taxed as pass-through entities by default, meaning that they are largely taxed similarly to sole proprietors — the business gets paid, the profits pass to you as the owner, and you get taxed. There is no “corporate” tax involved. 

This means that:

On a Federal Level

You’ll need to submit personal income tax returns using either Form 1040 (for single member LLCs) or Form 1065 (for multi-member LLCs). If you have employees, you will also be subject to federal income tax withholding. 

On a State Level

Your LLC may also need to pay sales or other activity-based taxes depending on the nature of your business. Profits passed through to members will be taxed at the individual income tax rate (0.25%–4.75%). If the LLC is taxed as a corporation, it will pay corporate income tax directly at a flat rate of 4%. 

You’ll also need to register for state income tax withholding if you plan to hire employees for your business.

On a Local Level

Your LLC may be responsible for paying local property taxes or additional sales and use taxes imposed by the county or municipality where your business operates. These local taxes are set independently and can vary by jurisdiction, so it’s important to check with your local government to understand your specific obligations.

For more information on the Oklahoma-specific LLC tax obligations that may apply to you, we recommend having a look at our in-depth Oklahoma LLC Taxes guide. Alternatively, you can schedule a free online consultation with 1800-Accountant for all your tax-related questions. 

4. Get Business Insurance for Your LLC in Oklahoma 

Even though an LLC offers limited liability, you’ll still likely need to purchase some form of business insurance to protect your LLC’s assets. 

This is because an LLC’s default limited liability protects your personal assets, not the business’s. Some of the most common types of business insurance include:

• General Liability Insurance: This is a broad insurance policy that protects your business from lawsuits. Most small businesses end up getting general liability insurance.
• Professional Liability Insurance: This is a business insurance policy for professional service providers (consultants, accountants, etc.) that covers against claims of malpractice and other business errors.
• Workers’ Compensation Insurance: This type of insurance covers medical expenses and lost wages if an employee is injured while performing job duties, and is required for any Oklahoma business with one or more employees.

5. Learn How to Properly Sign Your LLC’s Legal Documents

Improperly signing a document as yourself and not as a representative of the business can leave you open to personal liability. 

When signing legal documents on behalf of your company, you we recommend following this formula to avoid any problems:

• Formal name of your business
• Your signature
• Your name
• Your position in the business as its authorized representative

It’s important to be consistent and sign all official documents using this format; this will help protect your personal assets by clearly showing that the agreement is with the LLC, not you as an individual.

6. Submit an Annual Report for Your Oklahoma LLC

Oklahoma requires LLCs to file an annual certificate (i.e., annual report) with the Secretary of State along with a $25 filing fee. These annual certificates must be submitted either online or by mail each year by the end of the anniversary month in which your LLC was formed.

While Oklahoma doesn’t charge any late fees if you miss this filing deadline, your LLC will lose its “good standing” 60 days after the due date.

Note: Oklahoma may dissolve or revoke your LLC after three years for failure to file an annual certificate.

To stay on top of this deadline and other important compliance tasks, we recommend hiring a professional registered agent service — they can help ensure you never miss a filing.
