EIN Documents Explained

  • updated 2 wk ago

EIN stands for Employer Identification Number. This is a number issued by the United States Internal Revenue Service (IRS) and is used for filing your federal payroll taxes. Sometimes it is referred to as FEIN, or Federal Employer Identification Number.

There are several documents that contain your EIN, and all are issued by the IRS.

  • Form CP575

  • Form 147c

  • A completed SS-4 (the returned version from the IRS)
