What is a DBA, or Doing Business As? Understanding Assumed Business Names

What is a DBA?what is a DBA?

A DBA, which means "doing business as," is simply a fictitious name registration, also referred to as an assumed business name. It’s a way for a company to operate under a name other than its registered name. However, electing a DBA does not provide the same legal protections as having a separate business entity, such as a Corporation or LLC.

Every day, people inquire about setting up a DBA for their Delaware LLC or Delaware corporation. Business owners often choose to operate under multiple, different names for a number of different ventures. For example, ABC Company, Inc. may find the need to set up multiple, different DBAs using the names XYZ Landscaping, Inc. and 123 Construction, Inc.

While both XYZ Landscaping, Inc. and 123 Construction, Inc. are both assumed business names that are still legally recognized as ABC Company, Inc., the fictitious names can better convey the services and products the company offers its potential customers.

Do I need a DBA?

There are a few scenarios where it may be beneficial to apply for a DBA. However, in my experience, the current trend has business owners leaning toward incorporating a Delaware LLC or corporation with the actual name under which they plan to operate. Since the company name is often linked to a website, trademark, patent, logo or some other type of branding, setting up the DBA is kind of unnecessary.

Still, some situations do make a lot of sense for filing a DBA. Some examples of such situations would be:

  • A business begins to offer a product or service that does not fit under the registered company name. For instance, a bicycle repair shop that begins selling car tires may want a separate name for that piece of the business.
  • A company formed in Delaware only needs to have a name that is unique to Delaware. However, if the company applies for Foreign Qualification in another state, such as California, the name must also be unique in California. If the original name of the company is already being used by another business in California, the company can create a DBA to operate in that state.
  • Franchise owners often use DBAs. Because they only own their independent franchise business(es) and are not owners at the corporate level, they typically form their own company under a different name, then use the franchise name as the DBA. For example, a Wendy’s owner in Miami might form “Miami Restaurant Holdings, Inc” as the company owning the franchise, then file a DBA to operate as Wendy’s of Miami.

For these situations and many others, it is not uncommon for people to set up a DBA as a fictitious name for a corporation or LLC formed in Delaware. The question then becomes, where do I setup the DBA?

Where can I set up a DBA?

Traditionally, in Delaware, the DBA registration is completed in the county in which the company predominantly operates and does business. Next you might be wondering if you need to file for your LLC or corporation DBA in Delaware. Again, it depends where your company physically operates and transacts business. If the company is actually located and conducting business in the state of Delaware, then a Delaware DBA filing will typically be necessary.

You can fill out the necessary forms online to set up your DBA in Delaware. Depending on where in Delaware the company is headquartered, the DBA registration can be filed with the New Castle, Kent or Sussex County Prothonotary's Office. Usually, DBA registration will require the following information:

  • Name and address of the corporation or LLC
  • Date of formation
  • The DBA or fictitious name
  • Nature of business
  • Names and addresses of members/directors/officers
  • Contact phone number
  • Name of authorized person signing the title and notarization

If your company does not operate in Delaware—if it operates in any other state—the same rules, in general, apply for DBAs. The application for aDBA is still handled at the county level. If your Delaware LLC or corporation is operating in another jurisdiction, you may need to register for Foreign Qualification before filing for the DBA.

Multiple DBAs

We are sometimes asked how many DBAs a single LLC or corporation can have. The answer is that there is typically no limit that states or counties impose. Your company can have one, two, or ten DBAs if it wishes.

However, you should always consider if multiple DBAs are the most strategic way to proceed. While they do allow your business to operate under multiple names, hosting multiple DBAs at the same time can also present some issues, such as:

  • Higher overall risk by having each “arm” of the business under the same company
  • Complicated tax filing
  • Confusion for customers and vendors
  • Additional costs for each DBA filed

DBA vs. Multiple LLCs

How to structure multiple businesses As a final point, our clients sometimes are conflicted between utilizing a DBA and just setting up a separate LLC in addition to the one they already operate. There is no blanket rule about which is correct or incorrect; rather, each situation involves its own unique circumstances, as well as the preferences of the business owner.

It is important to keep in mind that using multiple LLCs does provide a greater level of protection and lower overall risk due to having each LLC be a separate legal entity. Issues that arise in one LLC typically do not put the other LLC's assets at risk. This is not true of DBAs, where the registered LLC and each other DBA are all considered to be the same legal entity.

Hi, we are a Harvard Business Services customer. We setup a Delaware Single Entity LLC. We have now branched out into a related industry and want to be able to open a business checking account in a different company name than our legal name. Can we open a checking account using a DBA or do we need to create another LLC?

HBS Staff replied: Friday, September 25, 2020

This is a question that would be best answered by your bank. Each bank's rules are different and they make their own decision about what name can be used on the accounts. Sorry we cannot be of more assistance!

I have an LLC I wish to add a DBA to. I wish to keep my LLC protection, can I keep under same LLC protection? How much do I look to pay?

HBS Staff replied: Monday, August 17, 2020

Your DBA simply allows you to operate your business with an alternate name. The LLC structure and protections remain in place, but keep in mind that if you have multiple lines of business, any liabilities, debts, etc. are not separated as they would be if you had two separate LLCs. DBAs are typically filed at your county offices, so please check with them in regards to price.

Hi, We have recently incorporated MoMo Me LLC in Delaware with HBS's assistance. Please can we use MoMo Me as our trading name or DBA?

HBS Staff replied: Monday, February 17, 2020

Typically, our clients will choose how they want to market their own company name, such as with or without the LLC suffix. If you are unsure of what is permitted, you can check with your local county offices or ask your lawyer or tax professional.

If you run Delaware corporation as an internet company that does not do business within Delaware, are you required to register any fictitious name in Delaware counties? Will the State of Delaware allow you to use fictitious names without registration if not doing business within the state?

HBS Staff replied: Wednesday, September 11, 2019

A DBA is typically registered with the county of the state in which the DBA is needed. If your company is already filed in Delaware, you generally are not required to have a DBA in Delaware. An attorney would be the best person to advise you on your particular situation.
