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, allowing you to identify your business to the IRS and the state of Hawaii. While sole proprietorships without employees might use their social security number, an EIN becomes essential as your mobile development business grows, especially when forming an LLC or corporation.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your mobile app development business requires an EIN. Generally, LLCs, corporations, and businesses with employees need one. Sole proprietors without employees might not, but it's often beneficial for separating business and personal finances.
  2. Choose Your Business Structure: Decide on your business structure: sole proprietorship, LLC, corporation, etc. In Hawaii, LLCs and corporations offer liability protection. Your choice impacts your tax obligations, especially concerning the Hawaii General Excise Tax (GET).
  3. Prepare Your Application Information: Gather the necessary information, including your business name, address, the responsible party's name and SSN/ITIN, and the reason for applying. You'll also need to specify your business activity (e.g., mobile app development).
  4. Apply Online Through the IRS Website: The easiest way to apply for an EIN is through the IRS website. The online application is free and generally takes only a few minutes to complete. The IRS provides an online assistant to guide you through the process.
  5. Complete the Online Form SS-4: Fill out the online version of Form SS-4, Application for Employer Identification Number. Answer all questions accurately and honestly. Be prepared to describe the nature of your mobile app development business.
  6. Receive Your EIN: Upon successful submission, you'll receive your EIN immediately online. You can then download, save, and print your EIN confirmation notice (Form CP 575).
