How to File an Amended E-File Tax Return
- 1). Have a copy of your e-filed tax return ready. Access the Internal Revenue Service IRS website and print a copy of the Form 1040X (see References). You cannot file the 1040X electronically.
- 2). Complete the top portion of the Form 1040X relating to name, address, filing status, Social Security number(s) and the year of the original tax return being amended. Write the amounts from your original tax return in Column A of the 1040X form. Put the changes of the original amounts (income, deductions, or credits) in Column B. Add or subtract the changes from Column A and Column B and enter the corrected amount in Column C. Complete the remaining sections and calculations on the 1040X form.
- 3). Print and sign the completed 1040X. Mail the 1040X form and your original tax forms to the Internal Revenue Service office in your area. If necessary, include a check for the amount you owe.
