How to Get an EIN for Your Mobile Developer Business in Idaho (2026)

As a mobile developer in Idaho, whether you're crafting the next hit app in Boise or serving clients statewide, an Employer Identification Number (EIN) is crucial for your business. This guide explains how to obtain an EIN for your mobile developer business in Idaho in 2026.

What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to identify your business. It's like a Social Security number for your company. While sole proprietorships without employees may not always need one, LLCs and corporations generally do.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your mobile development business structure (LLC, corporation, etc.) requires an EIN. Sole proprietorships without employees might not need one.
  2. Choose Your Business Structure: Decide on your business structure (LLC, S-corp, C-corp). This choice impacts your application and future tax obligations.
  3. Gather Required Information: Collect information such as your business name, address, the responsible party's (owner, partner, member) name and SSN/ITIN.
  4. Complete the IRS Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. You can download it from the IRS website.
  5. Submit Your Application: Apply online through the IRS website for the fastest processing. You can also fax or mail the form, but processing times will be longer.
  6. Receive and Store Your EIN: Once your application is approved, you'll receive your EIN. Keep this number in a safe place, as you'll need it for various business activities.
