Students or parents who file an amended federal tax return cannot use the IRS Data Retrieval process on their FAFSA. Instead, they must request a tax return transcript and tax account transcript, as the return transcript only contains the original information. Both documents together will be needed to complete the verification process. If you choose to order these documents by paper, you must use the IRS Form 4506-T. If you choose to order these documents online, please visit https://www.irs.gov/pub/irs-pdf/f4506t.pdf.
