How to Form a Sole Proprietorship in District of Columbia

Quick Answer

Forming a sole proprietorship in the District of Columbia is straightforward since it’s the default business structure for single-owner businesses. Unlike corporations or LLCs, sole proprietorships don’t require formal registration with the DC Department of Consumer and Regulatory Affairs (DCRA). However, you’ll need to obtain necessary business licenses, register a trade name if operating under a name other than your own, and obtain an Employer Identification Number (EIN) for tax purposes.

Step-by-Step Formation Process

1. Choose Your Business Name

   • You can operate under your legal name without registration
   • If using a different name, you must file a Trade Name Registration with DC DCRA
   • Search the DC business name database to ensure your desired name isn’t already taken

2. Register Your Trade Name (If Applicable)

   • File Form FR-101 (Trade Name Registration) with the DC Department of Consumer and Regulatory Affairs
   • Submit the form online through the DC Business Portal or by mail
   • Contact the Secretary of State for current information regarding filing fees

3. Obtain Required Business Licenses

   • Research DC business license requirements for your specific industry
   • Apply for a Basic Business License (BBL) through the DC Business Portal
   • Additional professional or industry-specific licenses may be required

4. Apply for an Employer Identification Number (EIN)

   • File Form SS-4 with the IRS online, by phone, fax, or mail
   • An EIN is required if you plan to hire employees or want to separate business and personal finances
   • The EIN application is free directly through the IRS

5. Open a Business Bank Account

   • Use your EIN to open a dedicated business bank account
   • This helps maintain separation between personal and business finances

Registered Agent

Unlike corporations and LLCs, sole proprietorships in DC are not required to maintain a registered agent.

If you operate from a home office, you can use your residential address. For businesses requiring a more professional appearance or those needing mail forwarding services, commercial registered agent services are available but not mandatory.

Can I convert my sole proprietorship to an LLC later?
