How to Get an EIN for Your First-Time Founder Business in District of Columbia (2026)

Congratulations on taking the leap into entrepreneurship in the District of Columbia! As a first-time founder, understanding the nuances of business formation can feel overwhelming. One crucial step is obtaining an Employer Identification Number (EIN) from the IRS. This guide will walk you through everything you need to know about getting an EIN for your new DC business in 2026.

What is an EIN?

An Employer Identification Number (EIN) is essentially a Social Security number for your business. It's a unique nine-digit number assigned by the IRS to identify your business entity. You'll need an EIN to open a business bank account, hire employees, and file certain taxes. Even if you're a single-member LLC in DC, you might need an EIN.

How to Apply for an EIN

  1. Determine Your Eligibility.: Ensure your business is eligible for an EIN. Generally, any business operating in DC that isn't a sole proprietorship without employees will need one. If you've formed an LLC or Corporation in DC, you're eligible.
  2. Gather Required Information.: Collect all necessary information, including your business's legal name, address (physical address in DC required), the responsible party's name and SSN/ITIN, and the reason for applying for the EIN.
  3. Complete Form SS-4.: You can apply for an EIN online through the IRS website. The online application is the preferred method. Alternatively, you can download Form SS-4 from the IRS website, complete it, and mail or fax it in (though online is faster).
  4. Submit Your Application.: If applying online, follow the prompts to submit your application electronically. If mailing or faxing, send the completed Form SS-4 to the appropriate IRS address or fax number (found on the IRS website).
  5. Receive Your EIN.: If applying online, you'll typically receive your EIN immediately after submitting the application. If mailing or faxing, it can take several weeks to receive your EIN in the mail.
  6. Verify Your EIN.: After receiving your EIN, verify its accuracy by checking the confirmation notice. Ensure that all information, including your business name and address, is correct.
