Form SS-4

What is Form SS-4?

IRS Form SS-4 is the form you use to apply for an EIN for your business.

(An EIN is the corporate equivalent of your social security number.)

In general, you can complete this online on the IRS's website, and have an EIN issued to you immediately. Be sure to save a copy of the PDF it generates!
