IRS Data Retrieval is a new system of verifying a financial aid applicant’s income information. In the “old days,” families often had to mail paper copies of their federal tax returns to every single college to which they were applying. This created a paper backlog and a security nightmare. Now families can easily verify that the numbers on their FAFSA form match the numbers on their tax return. And for those families that completed the FAFSA form early, with estimates, there’s a new, simple way to update the information.
