STEP 5: Obtain a Federal Employer ID number.

ยท The Federal Employer Identification Number (EIN) is used to report withholding taxes, and almost all businesses are required to obtain one. EINs can be obtained free of charge. You can obtain a number by calling 1-800-829-4933 (Monday through Friday, 7 A.M. to 10 P.M.), or filling out IRS Form SS-4, or by applying online.
