What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit tax identification number assigned by the IRS to business entities. It's like a Social Security number for your business, allowing the IRS to identify your business for tax purposes. Whether you're forming an LLC or a corporation with your co-founder, you'll likely need an EIN.

How to Apply for an EIN

Determine Your Eligibility: Ensure your co-founder business entity is legally formed and located in the United States or U.S. territories. You must have a valid Taxpayer Identification Number (SSN, ITIN, or another EIN).
Choose Your Responsible Party: Designate a 'responsible party' – someone who controls, manages, or directs the entity and the disposition of its funds and assets. This is usually one of the co-founders.
Complete the Online EIN Application (Form SS-4): Access the IRS website and complete the online EIN application (Form SS-4). Provide accurate information about your co-founder business, including its legal name, address, and the reason for applying.
Submit Your Application: After completing Form SS-4, submit it electronically through the IRS website. The online application is the fastest way to obtain an EIN.
Receive Your EIN: Upon successful submission, you'll receive your EIN immediately online. The IRS will also send you a confirmation notice (CP 575) by mail.
Verify Your EIN: Use your EIN on all official business documents, tax returns, and applications. Verify the accuracy of the information on your CP 575 form when it arrives.
