How do I get an EIN number for a new business?

US tax forms & filing

Apply directly with the IRS using Form SS-4. If you have an SSN or ITIN, the online application issues the number immediately. Without one, you file by fax or mail and wait.

You need the legal entity name, the formation state, and a responsible party before you start. Our step-by-step guide to getting an EIN covers each field on the SS-4 and the mistakes that cause the IRS to reject an application.

We handle this for founders running US companies.

Check your EIN confirmation letter (CP 575) first. If that is gone, look at a previously filed tax return, a business bank account application, or any 1099 you have issued. Your bank or your payroll provider will also have it on file.
