What is an EIN?

An EIN, or Employer Identification Number, is a unique nine-digit number assigned by the IRS to identify your business entity. Think of it as a Social Security number for your mobile development company. It's required for various business activities, including opening a business bank account, filing taxes, and hiring employees.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your mobile development business structure requires an EIN. LLCs with multiple members, corporations, and businesses with employees generally need one. Sole proprietorships without employees typically do not, but may want one for liability reasons.
  2. Choose Your Business Structure: Decide on your business structure (LLC, S-Corp, etc.). This will impact your tax obligations and the information you'll need to provide on the EIN application. For mobile developers in California, an LLC is often a good starting point.
  3. Gather Required Information: Collect all necessary information, including your business name, address, the responsible party's name and SSN/ITIN, and the reason for applying for the 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 easiest way to obtain an EIN.
  5. Submit Your Application: Review your application carefully and submit it electronically through the IRS website.
  6. Receive and Store Your EIN: Once your application is processed, you'll receive your EIN. Keep this number in a safe place, as you'll need it for various business activities.
