Amendments

Tax Amendment dates and forms by state are listed below. Tax amendments are generally due as soon as you discovered an error on your eFiled or filed state tax return.  If you filed your income tax return on time and you do not owe taxes as a result of the tax amendment, generally you should not be subject to a late payment penalty. 

In some cases, your state and/or the IRS may be able to correct the error on your tax return over the phone. See how to contact your state by clicking on the map below or see how to contact the IRS here.

Some errors that may require a tax amendment are:

  • Mathematical error on original return
  • Addition income to report, such as a form received after filing
  • Filing status adjustment
  • Dependent status adjustment
  • Tax credit adjustment
  • Tax deduction adjustment
  • Protective claim for refund
  • Reservation source income adjustments
  • Pass-through entity adjustments
  • Federal or state audit and/or adjustments
  • 2020 unemployment exclusion adjustment (if not automatic by state).
