What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to business entities operating in the United States. Think of it as a Social Security number for your business. It's used to identify your business for tax purposes and is essential for various business activities, such as opening a bank account, hiring employees, and filing taxes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your business entity requires an EIN. Generally, LLCs with more than one member (or electing to be taxed as a corporation), corporations, partnerships, and businesses with employees need an EIN.
  2. Choose Your Business Structure: Your business structure (LLC, corporation, etc.) impacts how you apply for an EIN. Make sure you've officially formed your business with the California Secretary of State before applying.
  3. Gather Required Information: You'll need information about your business, including its legal name, address, the responsible party's name and Social Security number, and the reason for applying for the EIN.
  4. Complete the IRS Form SS-4: You can apply for an EIN online through the IRS website. The online application is the easiest and fastest method. Alternatively, you can mail or fax Form SS-4, but processing times will be significantly longer.
  5. Submit Your Application: If applying online, you'll receive your EIN immediately after submitting the form. If applying by mail or fax, it can take several weeks to receive your EIN.
  6. Receive and Store Your EIN: Once you receive your EIN, keep it in a safe place. You'll need it for opening a bank account, filing taxes, and other important business activities.
