Oklahoma Business License: Who Needs One & How to Apply (2025)

What Is a Business License in Oklahoma?

A business license is a permit issued by a local, state, or federal body in order to allow businesses to perform a specific business activity and/or operate legitimately. 

So, if there isn’t a “general business license” in Oklahoma, what exactly is there?

Well, Oklahoma — like the vast majority of states — imposes different requirements depending on where you’re located and what you actually do. 

For example:

• A restaurant in Oklahoma City will need a food service establishment license from the Oklahoma State Department of Health, as well as local permits from the Oklahoma City Planning Department including zoning approval and a Certificate of Occupancy.
• A hair salon in Tulsa will need professional cosmetology licenses for all stylists from the Oklahoma State Board of Cosmetology and Barbering, plus a local business license from the City of Tulsa.
• A retail store in Norman selling taxable goods will need a Sales Tax Permit from the Oklahoma Tax Commission and should check with the City of Norman for any local business license requirements.
• A construction contractor in Broken Arrow will need a construction industries board license from the Oklahoma Construction Industries Board if performing commercial work over $50,000, plus local permits from the City of Broken Arrow Building Permits Division.

It all depends on what you do, and where you’re located. There is no “business license” that you will need to obtain just to operate no matter what, and while most businesses will need some form of business license to operate, this will not be the case for everyone.

How to Get a Business License in Oklahoma

The process of obtaining a business license in Oklahoma will depend on the permit in question, but generally involves completing the following steps:

1. Form a Business Structure & Obtain an EIN

We recommend formalizing your business before acquiring a business license in order to avoid potentially having to repeat this process again later down the line. 

This also gives other benefits depending on the business model, such as:

• Personal liability protection
• Improved legitimacy 
• Larger access to loans and corporate finance

Note: You should obtain an Employer Identification Number (EIN) after forming your LLC. You can have a look at our How to Get an EIN overview for more information. 

2. Apply for the Right Business License in Oklahoma

This step will depend on the business license in question.

Oklahoma Local Business Licenses

Many Oklahoma cities and counties require local business licenses or permits to be obtained. This can be in addition to the common state-wide licenses talked about above.

Here are some common local permits you may need:

• Zoning Permits: You may need this to ensure that your business’s location is zoned appropriately and is compliant with local laws. This verifies that your business activity is allowed in your chosen location (e.g., if you were based in Enid, you would check with the City of Enid Planning Services).
• Sign Permits: These can be required before installing business signage. Most cities regulate the size, placement, and illumination of business signs (e.g., if you were based in Bartlesville, you would apply through the City of Bartlesville Community Development).
• Certificate of Occupancy: Required for most businesses before they can legally occupy a building or space. This verifies that the structure meets building codes and is safe for the intended use (e.g., if your business is in Midwest City, you would obtain this from the Midwest City Building Inspections).
• Home-Based Business Permits: If you’re operating a business from your residence, many cities require special permits to ensure compliance with residential zoning laws (e.g., if your home business is in Shawnee, you would check requirements with the City of Shawnee Planning Department).

To find your local county or city’s official contact information and licensing requirements, you can visit the Oklahoma Municipal League.

Oklahoma Business License Renewal

Depending on your business license, you may need to renew it periodically — usually within one or two years. 

This is not required for a sales tax permit, but is required for practically all professional licenses.

Several of the local permits will also need to be renewed annually; this includes health department permits, signage permits, and fire department permits, which generally all need to be renewed annually.

Having said that, this will depend on both your location and the license in question.
