Federal Employer Identification Number (EIN)

EINs are used to identify the tax accounts of businesses. You need to get an EIN if you have employees or operate your business as a partnership or corporation. An EIN is also needed if you have a Keogh retirement plan or file certain tax returns. Form SS-4, An Application for Employers Identification Number, is used to request an EIN.
