I filed an amended return (Form 1040-X) last year. When e-filing do I use the AGI from the original return or the AGI from the amended return as my e-file signature?
When e-filing your return for the current year, in most cases you would use the AGI from the prior year's amended return.
During the e-file process the IRS matches their files against what prior year AGI they have on file for your SSN (social security number) and compare it to the number that you enter for your prior year AGI. The numbers must match exactly or the IRS will reject the electronically filed return.
In most cases, when you file an amended return, the IRS will update their records to reflect the corrected AGI filed on your amended return. So when entering your current year e-file signature information, if you choose to use the prior year AGI, enter the corrected AGI.
If you filed an amended return (1040X) recently: You should probably contact the IRS to find out exactly what they have on file. The IRS may not have updated their records with the corrected AGI. In fact, it may be several weeks or months before this information gets updated in the IRS database. You may contact the IRS at 1-800-829-1040.
Check IRS Database: If you are unsure of the Prior Year AGI amount, you can visit the IRS website to find out the AGI for the prior year. You can get a transcript of the return in about 15 minutes online or you can have the transcript mailed to you. The IRS does have requirements that you must meet to get the transcript online. See the IRS website for more details.
