What is an EIN?

An EIN, or Employer Identification Number, is a unique nine-digit number assigned by the IRS to identify your business. It's like a Social Security number for your company. You'll need an EIN to hire employees, open a business bank account, and file business taxes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your software development business structure (LLC, S-Corp) requires an EIN. Sole proprietorships without employees may not need one, but it's often beneficial for liability protection and credibility, especially in Indiana.
  2. Choose Your Business Structure: Decide whether to operate as an LLC, S-Corp, or other entity. Your choice impacts your tax obligations and liability. Indiana offers a streamlined online filing system for LLCs and corporations.
  3. Gather Required Information: You'll need your business name, address, the responsible party's (owner/member) name and Social Security number, and the reason for applying. Having this information ready will expedite the process.
  4. Complete the Online Application: Access the IRS website and complete the online EIN application (Form SS-4). The application is free. Answer all questions accurately and honestly.
  5. Submit Your Application: Once you've completed the form, submit it electronically through the IRS website. You may also fax or mail the application, but online submission is the fastest method.
  6. Receive Your EIN: Upon successful submission, you'll receive your EIN immediately if applying online. If applying by mail or fax, it can take several weeks. The IRS will send you a confirmation letter (Form CP 575) with your EIN.
