Frequently asked questions

Does an EIN cost money?

No. Applying directly with the IRS is completely free. Any site charging you for an EIN is a third party, not the IRS.

Do I need an EIN as a sole proprietor?

Not always — a sole proprietor with no employees can use their SSN. But an EIN is recommended to keep business and personal finances separate and is required to hire employees.

Can I apply for an EIN online from anywhere?

The online tool requires the responsible party to have a valid SSN or ITIN. International applicants without one can apply by phone, fax, or mail.
