What forms do I send with an amended return?

[MollsBBU · Accepted solution]

Yes. Send the entire new 1040 with the corrected info, plus the 1040X which is like a cover sheet that highlights the changes. Also attach any forms that are related to the changes (including any W-2's, 1099's, etc). Then, send the same information to the State as well, including Federal and State forms. 

• For help, please find the Filing Instructions, which print out when you print your amended return.
