Can i cancel the tax return that i filed yesterday? I forgot to mentioned something.

[Texas Roger · Accepted solution]

No you can't cancel it. Once you submit it for efiling, it's just like dropping it in the post office box. You must wait until it's either accepted or rejected.

If your return is rejected by the IRS, you can correct the problem and fix the reason for rejection and re-efile your return. If your return is accepted by the IRS, you must prepare, print, sign and mail an amended tax return form 1040X to correct the problem. 

DO NOT change your original tax return until you start the amended return. If you have already changed it from the way it was originally filed and accepted, you must change it back before you start the amended return. Wait until you receive the refund from your original return before beginning your amended return to make sure you enter the correct amount. The amended return form 1040X will not be available in TurboTax until mid February.  Amended returns cannot be efiled.

Okay thank you for your respond.

Well, back when dinosaurs roamed the US and I prepared a return on paper I filed before a received one of my W-2s.  I was told by the IRS that if you can file another return before the due date.  They will accept the most recent one filed.   I added a note with the return that I'd received the W-2 after I'd filed which was the reason for the change.  No 1040X was needed.  How that works in the electronic filing age I don't know.  I would contact the IRS or Tubrotax.

You can't do it that way any more. If you efile another tax return after an efiled return has already been accepted, the second one will be rejected. If you try to mail one in, the IRS won't even process it until the efiled one has already been processed.

Good to know.  Thanks Roger.
