What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit 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 your company for tax purposes. Even if you don't plan to hire employees immediately, an EIN is often required to open a business bank account, obtain business licenses, and file certain tax returns.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your SaaS business entity is eligible for an EIN. Generally, any entity formed as an LLC, corporation, partnership, or with employees requires 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 must have a valid Taxpayer Identification Number (SSN or ITIN).
  3. Complete Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. This form requires detailed information about your SaaS business, including its legal name, address, business activity, and the reason for applying for an EIN.
  4. Submit Your Application: Submit Form SS-4 to the IRS. You can apply online through the IRS website, by fax, or by mail. Online applications are generally processed immediately.
  5. Receive Your EIN: Once your application is processed, you will receive your EIN from the IRS. If you applied online, you'll typically receive it immediately. For faxed or mailed applications, it may take several weeks.
  6. Verify Your EIN: After receiving your EIN, verify its accuracy by checking the confirmation notice. Contact the IRS immediately if you find any discrepancies.
