How to File an Amended Delaware Return


amend Delaware taxes
Delaware
"The First State"

If you need to change or amend an accepted Delaware State Income Tax Return for the current or previous Tax Year, you need to complete Form 200-01-X (residents) or Form 200-02-X (nonresidents and part-year residents) Forms 200-01-X and 200-02-X are Forms used for the Tax Amendment. You can prepare a 2018 Delaware Tax Amendment on eFile.com, however you cannot submit it electronically. In comparison, the IRS requires a different Form - Form 1040X - to amend an IRS return (do not use Form 1040 for an IRS Amendment). 

The IRS might send you a notification to change an error on your Return, or you might have discovered an error. If you or the IRS amended or changed one of your IRS Tax Return(s), the IRS will report this to the Delaware Tax Agency, thus you should file a Delaware Amendment within one year.
