What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to identify your business entity. It's essentially a Social Security number for your business. 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, an EIN can offer added privacy and credibility.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your software development business structure requires an EIN. Most LLCs, corporations, and partnerships need one. Single-member LLCs without employees can often use their SSN, but an EIN is still recommended.
  2. Choose Your Business Structure: Decide on your legal structure: Sole proprietorship, LLC, S-Corp, C-Corp, or partnership. This decision impacts your tax obligations and EIN requirements. Many Colorado software developers choose an LLC for liability protection and tax flexibility.
  3. Gather Required Information: You'll need information about your business, including its legal name, address, the responsible party's name and SSN, and the reason for applying for the EIN.
  4. Complete the Online Application: Go to the IRS website and complete the online EIN application form (Form SS-4). The application is free and generally takes about 15-20 minutes to complete.
  5. Submit Your Application: After completing the form, submit it electronically. In most cases, you'll receive your EIN immediately upon successful submission. Save a copy of your EIN confirmation for your records.
  6. Record and Protect Your EIN: Once you receive your EIN, store it securely and use it on all official business documents, tax forms, and bank account applications. Keep a copy readily available for reference.
