Why start and file a DBA in Delaware?

More than one million business entities call Delaware their legal home. However, it's important to know that several other factors have led to Delaware's dominance in business formation.

Even the Delaware Secretary of State provides a wide range of services and resources for all entity formations, including Delaware DBAs.

As you can see, Delaware is a haven not just for tax purposes, but because the state offers a complete package of business entity services. Entrepreneurs interested in filing a DBA in Delaware can get started by following our free guide.

How to File a DBA in Delaware

For those unfamiliar with the acronym, DBA stands for "doing business as." Delaware refers to a DBA as a Fictitious Name and also as a DBA. No matter which type of business structure you have incorporated as, whether it's a sole proprietor, partnership, corporation, or LLC, if you plan to operate your business under a name different than your real name or an existing corporate name, then you need to file a DBA.

What else can you do with a DBA? Here are a few additional benefits you'll receive by registering a fictitious name in Delaware:

  • The ability to open a business bank account. You are unable to use your personal bank account to issue or receive checks under your business name. Filing for a DBA allows you to open a bank account under your startup's name, as most banks will require a certified copy of your DBA before you can open an account. Once you have a business bank account, you may collect checks and payments under your company's name.
  • Public advertising. Now that you have registered your official business name, you may begin publicly advertising and marketing under the DBA. This will help increase the visibility of your business
  • Create a separate business identity. Small businesses look much more professional once they file for a DBA. The assumed name allows them to establish a separate business identity for customers and vendors. This allows you to present your business in a professional light.
  • Discourage others from usage. You'll be able to protect your brand and discourage others from registering your name by officially registering your DBA.

The first step is determining if a DBA is right for you. There are a few common situations where registering a DBA makes the most sense:

  • Sole Proprietors: Let's suppose Jane Smith is a graphic designer doing work as a sole proprietorship (no LLC or corporation formed). She may wish to conduct business with her clients as "Designs by Jane," as well as open a bank account and accept checks under that name. Filing a DBA for the name Designs by Jane would allow her to do so.
  • LLC/Corporations: In the case that you have already filed an LLC or Corporation for your business, you may register another name for your business with the state. Let's say you filed an LLC for your auto repair business under the name "L.A. First Auto Repair" but have decided to expand your business into auto detailing. You could file a DBA for "L.A. First Auto Detailing" as a second name for your business. Doing this ensures you keep these two separate business activities distinct.
  • LLC/Corporations:
    In Delaware, your corporation or LLC's full legal name may include an indicator (such as Inc or L.L.C). If your company's full name is "Doggie Day Care, INC," but you wish to operate your business as "Doggie Day Care," you would file for a DBA without the indicator.

The next important step seems obvious: you'll need to decide on a name to register. Here are a few rules to keep in mind as you come up with a name in Delaware.

  1. No two fictitious names in Delaware can be similar or the exact same. In other words, a DBA cannot mislead the public by being deceptively similar to any other business name.
  2. A DBA name cannot include a corporate indicator, like Corp or LLC, or any other words that imply an entity type, unless the business has been incorporated as an LLC or corporation. This is to prevent a sole proprietor from posing as an incorporated business.

How do you find out if a DBA name is available in Delaware?

There are a few approaches you can take once you have chosen a name that meets the guidelines listed above in order to determine if the name is available to register. One basic approach is to do a Google search for other Delaware businesses with the same name.

While it may not prove that the name you want to register is available, it is an easy way to weed out any names that are already taken. You can also check to see if the web domain for your business name is available, since it is likely you will need a website domain that matches your company name.

Another, more reliable approach is to conduct a Delaware DBA Name search. MyCorporation may complete a thorough business name search on your behalf, and report back the findings to help you avoid unnecessary rejections.

Tip: Even when the DBA name has been checked, you should avoid ordering business cards and advertising signage until you receive notification of filing from the Secretary of State.

According to the State of Delaware, there are several filing options available for obtaining a DBA. You may choose one of the three filing methods:

Now that you have determined the name is available for registration, it's time to complete the filing with the forms provided by your county. It is important that you file your DBA in the county where you plan on operating your business. Most counties in Delaware require similar, basic information:

  1. County name
  2. Trade name.
  3. Business address and phone number.
  4. Person, firm, or association.
  5. Names and addresses of all owners in the business.
  6. Date of formation.
  7. Nature of business.
  8. Owner signature, title, date, and the signature of the notary public.
Tip: Most counties in Delaware will allow you to register multiple fictitious names at a time if desired.

Filing a DBA in Delaware Frequently Asked Questions

No. A business license is required of all businesses, whereas a DBA is required only if the business is operating under a name different from the name of the owner.

In Delaware, all businesses are required to file for a general business license (sometimes referred to as a business tax certificate). Business licenses are issued by cities and municipalities, and every city in California differs in their requirements. If you plan on operating your business in multiple cities, you will need to apply for a business license in each location. Some additional permits may be required in addition to a general business license, which may need to be filed with the county or the state. You can find out about the specific licenses applicable to your business by checking with the city offices where you will conduct business, or by using MyCorporation's business license compliance package. Our team of skilled professionals will identify the licenses required by your business and provide you with all the information you need to file.

You may also utilize Delaware One Stop Opens in a new window, which helps Delaware businesses find appropriate permit information.

A DBA does not grant exclusivity for the use of a business name. DBAs identify the business and claim the business's name, but they only claim the name itself. Once you file for a DBA, the name cannot be used by another business on the state level. However, if a business in a different state wanted to register the same DBA as your business, they could so long as no other business in their state had already claimed that name. It is also possible to trademark a DBA. This would offer nationwide protection against infringement.

A Certificate of Assumed Name does not require renewal once approved by the state and county.

Filing a DBA in Delaware will not impact your taxes, as it does not alter your tax status. Only the name you conduct business as will change. The structure of your business is what determines how you will be taxed (sole proprietor, corporation, LLC, etc.), so you will continue to pay taxes as usual after filing a DBA.

If you are not planning to continue using your DBA, it is advised that you consult with the appropriate state agencies to determine the next steps moving forward with your DBA.
