What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to identify your business. It's essentially a Social Security number for your company, allowing you to hire employees, open business bank accounts, and file taxes under your business name. Even if you're a sole proprietor, an EIN can offer added credibility and privacy.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your web development business is eligible for an EIN. Generally, any entity formed as an LLC, corporation, partnership, or with employees needs an EIN. Sole proprietors may also apply.
  2. Choose Your Business Structure: Decide on the legal structure of your business (e.g., LLC, S-corp, C-corp). This will impact your tax obligations and liability. Colorado offers online resources to help you choose the right structure.
  3. Gather Required Information: Collect all necessary information, including your business name, address, the responsible party's (owner or principal officer) name and SSN/ITIN, and the reason for applying for an EIN.
  4. Complete the Online Application (Form SS-4): Access the IRS website and complete the online EIN application (Form SS-4). The online application is the fastest and most efficient way to obtain your EIN.
  5. Submit Your Application: Review your application carefully and submit it electronically through the IRS website. Ensure all required fields are completed accurately.
  6. Receive Your EIN: Upon successful submission, you will receive your EIN immediately. The IRS will also send you a confirmation letter (Form CP 575) via mail or fax.
