What is an EIN?

An EIN, or Employer Identification Number, 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, used to identify it to the IRS for tax purposes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Illinois Web3 business is eligible for an EIN. Generally, any entity operating a trade or business within the U.S. needs an EIN. This includes LLCs, corporations, partnerships, and even sole proprietorships with employees.
  2. Choose Your Business Structure: Decide on your business structure (LLC, C-corp, etc.). This decision impacts your tax obligations and legal liability in Illinois. Wyoming DAO LLCs are a popular option, but may require qualification as a foreign entity in Illinois if doing business there.
  3. Gather Required Information: Collect all necessary information, including the legal name of your business, its mailing address, the name and Social Security number of the responsible party (owner, partner, or officer), and the reason for applying for the EIN.
  4. 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.
  5. Submit Your Application: Submit the completed Form SS-4 to the IRS. You can apply online, by fax, or by mail. Online applications are generally processed faster.
  6. Receive Your EIN: Once your application is approved, you'll receive your EIN from the IRS. This usually takes a few minutes for online applications or several weeks for mail-in applications.
