What is an EIN?

An EIN is essentially a Social Security number for your business. It's a unique nine-digit tax identification number assigned by the IRS to business entities operating in the United States. You'll use it for various business activities, including filing taxes, opening a bank account, and hiring employees.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your Hawaii marketplace business structure requires an EIN. LLCs with more than one member, corporations, and businesses with employees generally need one.
  2. Choose Your Business Structure: Decide on the legal structure for your Hawaii marketplace (e.g., LLC, S-corp, C-corp). This decision impacts your tax obligations and liability. Consider consulting with a business advisor familiar with Hawaii's unique GET implications.
  3. Gather Required Information: You'll need to provide information about your Hawaii marketplace, including its legal name, address, the responsible party's name and SSN/ITIN, and the reason for applying for the EIN.
  4. Complete the IRS Form SS-4: The application for an EIN is done using IRS Form SS-4. This form collects all the necessary information about your business. You can download it from the IRS website.
  5. Submit Your Application to the IRS: You can apply for an EIN online through the IRS website, by fax, or by mail. The online application is the fastest method.
