How to Get an EIN for Your Serial Entrepreneur Business in Hawaii (2026)

What is an EIN?

An EIN, or Employer Identification Number, is essentially a Social Security number for your business. Issued by the IRS, it's a unique tax ID that allows you to hire employees, open business bank accounts, and file taxes. Even if you don't plan to hire employees immediately, an EIN can simplify many business operations in Hawaii.

How to Apply for an EIN

  1. Determine Eligibility: Ensure your Hawaii business entity (LLC, C-Corp, etc.) is legally formed and requires an EIN. Most businesses operating in Hawaii, especially those with employees or multiple members, will need one.
  2. Choose Your Application Method: You can apply for an EIN online through the IRS website, by mail (Form SS-4), or by fax. The online application is the fastest and most convenient method for most Hawaii entrepreneurs. Lovie automates this process.
  3. Complete the EIN Application (Form SS-4): Provide accurate information about your business, including its legal name, address, responsible party (you), and the reason for applying. Be prepared to describe your business activity in detail.
  4. Submit Your Application: If applying online, submit the completed form electronically. If applying by mail or fax, send the form to the appropriate IRS address or fax number (check the IRS website for the correct Hawaii-specific details).
  5. Receive Your EIN: If you apply online, you'll typically receive your EIN immediately. If applying by mail or fax, it can take several weeks. The IRS will send you a notice (CP 575) confirming your EIN.
  6. Store Your EIN Safely: Keep your EIN in a secure location, as you'll need it for various business-related activities, including opening bank accounts, filing taxes, and applying for licenses and permits in Hawaii.
