When Do I Need to Prepare and File a Delaware Amended Tax Return?
If you are expecting a refund, you have up to 3 years to file a tax amendment form from the original tax return filing deadline, or as many as 2 years from the date when you paid the tax, (whichever is later).
However, if the IRS made changes to your federal income tax return, then you have up to 90 days from the date of the final notice to file your tax amendment form with the state of Delaware to reflect the federal return changes.
