What is form 1040X?
The individual taxpayer cannot change anything on the W-2 form. To correct an error on the originally filed income tax return you will have to use the 1040X Amended Individual Income tax return. File a separate Form 1040X for each year you are amending. Mail each form in a separate envelope. Be sure to indicate the year of the return you are amending on the front of the form. The 1040X form has one column where the Correct Amount is the only figure entered, making it easier to make changes to previously filed returns.
