Step 1: Choose a Business Structure

The type of business structure you choose to form will determine how you register the business with the district. Use our how to choose a business structure guide to help choose which business structure is best for you, whether it’s sole proprietorships, general partnerships, limited liability companies (LLCs), and corporations.

The factors you should consider when choosing a business structure will depend on your needs and wants for personal liability protection, tax liabilities, and paperwork to keep the company in compliance.

Recommended: We typically recommend forming an LLC for most entrepreneurs because this structure comes with personal asset protection, has no double taxation, and is pretty easy to maintain.

Sole Proprietorships and General Partnerships

By default, sole proprietorships operate as the same name as the owner while general partnerships must include the surnames of all the partners.

To use a different name to conduct business, the business owner(s) must file for a Washington D.C. trade name — also commonly referred to as a doing business as (DBA) name.

LLCs and Corporations

Both LLCs and corporations require unique names in Washington D.C. that must follow certain naming requirements:

Step 2: Check Name Availability

When registering a business name, it's important to make sure it's unique and no one else in your state formed a company with it or has control of it online as a domain name.

Domain Name Search

We strongly recommend that you also check to see if your business name is available as a web domain (URL). Even if you don't plan to create a business website today, you may want to buy the web address to prevent others from acquiring that domain name. If the web domain is available then it’s likely the name will also be available in a business search.

Washington D.C. Business Name Search

Next, search the Washington D.C. Department of Licensing and Consumer Protection business name search tool. This is an important step in the process because your filing will be denied if you try to file for a name already in use.

Search requirements can vary depending on your business needs. For example, a unique and available name is required to:

  • File for formal business structures like LLCs and corporations.
  • File a DBA name for any business structure.

A district-level name search isn’t required for informal business structures like sole proprietorships or general partnerships in Washington D.C. But, if you decide to register a trade name or DBA name, you’ll need to search the database to see if your desired name is unique and available.

Step 3: Form Your Business With Washington D.C.

Once you have selected your business structure and name, you will need to file your formation documents with the district, which will register your business with Washington D.C.

To register your Washington D.C. LLC, you'll need to file the Articles of Organization with the Washington D.C. Department of Licensing and Consumer Protection. You can apply online, by mail, or in person. Read our Form an LLC in Washington D.C. guide for details.

Or use a professional service like Northwest or LegalZoom to form your LLC for you.

To register your Washington D.C. corporation, you’ll need to file the Articles of Incorporation with the Washington D.C. Department of Licensing and Consumer Protection. Read our Form a Washington D.C. Corporation guide to learn more.

Additional Considerations

Protect Your Business Name With a Trademark (Optional)

Once you confirm the availability of your business name and secure it, you can choose to apply for a trademark for your business. This typically costs around $225 to $400 plus any attorney fees as well as a renewal fee every 10 years.

While this cost can be high for a start-up or fledgling business, it will give your company brand nationwide protection backed by federal law. That means if others try to do business with the same — or a similar — name as yours, you’ll have legal precedent on your side. For most small businesses, this really isn't necessary unless they are thinking of going national.

How to Change the Name of a Washington D.C. Business

Changing the name of a business in Washington D.C. can be done in two ways: by filing for a trade name or by submitting an amendment to the legal name of an existing business.

The first method, filing for a trade name (also known as a DBA name), is the easiest way to operate your business using a different name without needing to change its legal name.

A DBA name is the only way for sole proprietorships and general partnerships to have a different business name. It’s also the easiest method for LLCs and corporations to follow because it allows them to avoid filing an amendment or complicating their business operations while enabling them to operate with brand names that don’t include the necessary LLC or Inc. suffix required in a legal name.

If you want to change the legal name of your LLC or corporation, however, filing an amendment to the legal name of an existing business is your best option. Here are links to forms for both options:

You may submit both online or by mail along with the $220 filing fee.
