Printable Tax Form And Instructions 2016, 2015, 2014

Form 1040X is used to correct IRS Form 1040EZ, Form 1040A, and Form 1040.

See the Form 1040X instructions booklet for exceptions to this rule and more details on when and where to file.

Examples of when to use 1040X:

  • Missed a credit or deduction which reduces your tax due.
  • Found a shoe box full of receipts after you filed your return.
  • Correct an error on Form 1040, Form 1040A, or Form 1040EZ.
