Do you need the employers federal id number to file your tax return?

What you need to file your taxes is your W-2 form and any other tax forms and records that you need to accurately report income and expenses if itemizing. Your W-2 form has the employers federal and state identification numbers on the form. In every software program for tax return preparation it does require that all the information on the W-2 form is entered into the software. The danger in trying to file your return without the W-2 form is that all the information is needed and if you put in any data that is not on your actual form when received, you will probably have an incorrect refund or amount die and this will require you to file an amendment in order to correct this outcome. Why not just wait the extra week for your forms to come to you.
