What is a DBA?

A DBA, also known as “Doing Business As,” Trade Name, Assumed Name, or Fictitious Name, is a name used by a business that is different from the legal name of the business.

What is a DBA good for?

A DBA is required for many businesses in order to legally operate and provides information on the people operating a business.  In addition to the legal requirement, a DBA offers other benefits such as proving the existence of a business, opening a bank account under a business name, registering a merchant account to accept credit cards, and others.

Who needs to register for an Oklahoma DBA?

The requirements and need to register for a Trade Name vary, depending on the type of business entity.

Sole proprietorships are the most common entities to register a business name.

The legal name of a sole proprietor can be the owner’s full first and last name, which can be used without registering.  For example, if John Smith starts a business repairing computers but doesn’t use a business name, he wouldn’t need to register.  If John decides to name his business John’s Computer Repair, he will need to register.

A sole proprietorship has two types of name registrations available.

The first is a Trade Name, which is registered with the Secretary of State.  This registration is optional, but it will stop another business in the state from using the exact same name.

If a Trade Name registration is not obtained, a Sole Proprietorships may need a Certificate of Fictitious Name, which is a filing by the County Clerk in the county where the business is located to identify the owners of a business.  The main reason a sole proprietorship would need this certificate is if the bank requires it.

Partnerships will commonly register a Trade Name unless the name of the business is going to be the full first and last name of the owners.  Partnerships will register their name with the Secretary of State.

Corporations and Limited Liability Companies won’t typically register a fictitious name since a unique entity name is created during the formation process.  Some will file for a DBA if they have another business they want to operate under their corporate/LLC umbrella to keep the liability protection without forming another entity.

Are there any words you can’t use in a DBA?

DBAs can’t be registered using words that are related to banking or insurance unless the business is licensed to provide those services.  Additionally, words related to illegal activities are not allowed either.

Can someone steal my business name?

While registering your Trade Name will keep someone else from registering the exact same name in Oklahoma, it does very little from someone else operating a business under that name in other states. If stopping others from using your business name is important, you can protect it through a trademark.

Does a DBA need an EIN?

An EIN or Employer Identification Number is a unique nine-digit number that some businesses will register for through the Internal Revenue Department (IRS). An EIN is required for partnerships, corporations, multi-member LLCs, or any business that has employees.

Sole proprietorships and single-member LLCs without employees can use the owner’s social security number to identify the business.

There is no cost to get an EIN when registering directly from the IRS.
