What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit tax identification number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your business, used to identify your company for tax purposes.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your mobile developer business structure (LLC, S-Corp, etc.) requires or would benefit from an EIN. Even as a sole proprietor, an EIN can simplify banking and taxes. Check Indiana state requirements for LLCs.
  2. Choose Your Business Structure: Decide on your business structure (LLC, S-Corp, etc.). This impacts your EIN application. In Indiana, LLCs offer liability protection, while S-Corps can provide tax advantages.
  3. Gather Required Information: Collect information such as your business name, address, the responsible party's name and SSN/ITIN, and the reason for applying. Have your Indiana business formation documents ready.
  4. Apply Online via IRS Website: The easiest way to apply for an EIN is through the IRS website. The online application is free and generally processed immediately. Access the EIN Assistant tool.
  5. Complete the Form SS-4: This is the application form for an EIN. Fill it out accurately and completely, providing all the requested information about your Indiana-based mobile development business. You can also complete this form and submit via fax or mail, but online is fastest.
  6. Receive and Store Your EIN: Once your application is approved, you'll receive your EIN. Download, print, and store it securely. You'll need it for various business activities, including opening a bank account and filing taxes in Indiana.
