Register a Louisiana DBA

Registering a Louisiana trade name, also known as a DBA, is easy!

Your Louisiana trade name must be unique and must also meet Louisiana’s business name requirements.

First, visit the Louisiana Secretary of State’s website and search for your new DBA name to make sure it isn’t already in use.

Next, review the Louisiana naming requirements. In Louisiana, your trade name should NOT include:

  • Any business entity suffix, such as LLC, Incorporated, Corp., etc unless the business is actually an LLC, corporation, or etc.
  • The words bank, banker, banking, savings, safe deposit, trust, trustee, building and loan, homestead, or credit union without approval from the Louisiana Commissioner of the Office of Financial Institutions.
  • Words that falsely suggest that your company is a charity, nonprofit, or government organization.
  • The words “casualty,” "redevelopment corporation," or "electrical cooperative."
  • The words "engineer," "engineering," "surveyor," "surveying," (or any variations) without approval from the Louisiana Professional Engineering and Land Surveying Board.
  • Words that imply that the company is organized for any unlawful purpose. It also cannot contain any words “that consist of or comprise immoral, deceptive, or scandalous matter.”

We recommend checking if your name is available as a web domain (URL). You might not plan on starting a business website today, but you may want to prevent others from acquiring your URL.

Step 2: Register Your Louisiana DBA

In Louisiana, you must actually be using your trade name before you can register it. If you haven’t yet started using it, Louisiana allows you to reserve a trade name before registering it. If you would like to reserve a DBA for your company, you can do so online or by filling out and returning the Application for Reservation of Trade Name. There is a $25 fee to reserve a trade name, and it will be reserved for 120 days after the application is processed.

Your Louisiana trade name can be registered online or by mail with the Secretary of State. You can file online with the Louisiana geauxBIZ website or you can complete the Application to Register Trade Name form.

Some important sections of the form include:

  • Section 2: Applicant’s state of incorporation (if applicable)
  • Section 5: Type of business
  • Section 7: Date trade name first used

After Filing Your Louisiana DBA

If filing a DBA marks the beginning of your business journey, then there are a few more steps that you should take before getting started:

  • Create your Business’s Website - Every business needs a website. Luckily, drag-and-drop builders like GoDaddy and Wix make the job quick and easy. Check out our Best Website Builder article to find the tool that’s best for you.
  • Get your Business Finances in Order - You’ll need to separate your business finances from your personal ones. This is accomplished by opening a business bank account. If your business has long lead times or other cash flow irregularities, you can also look into a business credit card.
  • Protect Your Business - While an LLC will help to protect your personal assets in the case of a lawsuit, your business’s assets also need protection. Having the right business insurance will ensure that you’re covered if the worst happens. Most businesses start with general liability insurance as their base coverage.

DBA Louisiana FAQ

You can have as many DBAs as you can afford to create and are able to keep track of. Each one comes with additional incremental expenses and paperwork, meaning more is not necessarily better.

DBAs aren’t required to have a separate EIN because DBAs aren’t a business entity. The business entity that the DBA is under would have an EIN if an EIN is required.

To learn more about EINs and when you need one for your business, read our What is an EIN guide.

No. An LLC is a business entity, while a DBA is just a name for a business.

Sole proprietorships are often confused with DBAs, but they are not the same: a sole proprietorship is a business entity, therefore it can choose to become an LLC.

To learn how to form an LLC, visit our Form an LLC state guides.

A DBA can only have Inc. in the name if the business entity the DBA is attached to is a corporation.

Holding a rental property in your name and with a DBA will not afford you any protection. The best option is to form an LLC to protect your personal assets in the event of an issue with the rental property. In any case, it is always best to consult an attorney.

Getting a DBA is often a better choice than changing your business’s legal name. If you want to rebrand your company or focus on another line of business, filing for a DBA is a simpler process than filing for a legal name change.

Some state-level laws prevent DBAs that are too similar to existing ones from being used, but this varies from state to state. It is possible to trademark a DBA, which would offer stronger protection across state lines.
