What is an EIN?

An EIN, or Employer Identification Number, is a unique nine-digit tax ID assigned by the IRS to business entities. It's like a Social Security number for your business, used to identify it for tax purposes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Web3 business entity (LLC, C-Corp, etc.) is properly formed in California. You must have a valid business structure before applying for an EIN.
  2. Choose Your Responsible Party: Designate a 'responsible party' – an individual who controls, manages, or directs the entity and the disposition of its funds and assets. This person will be the primary contact with the IRS.
  3. Complete the IRS Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. You can download the form from the IRS website or complete the application online.
  4. Submit Your Application: Submit Form SS-4 to the IRS. You can apply online, by fax, or by mail. Online applications are generally processed fastest.
  5. Receive Your EIN: Upon successful application, you'll receive your EIN from the IRS. If you applied online, you'll typically receive it immediately. Mailed applications can take several weeks.
  6. Keep Your EIN Safe: Your EIN is confidential and should be protected. Use it only for official business purposes.
