Why have I been flagged for verification?
About a third of FAFSA applications are selected each year for a review process called verification. The purpose of verification is to make sure there are no errors on your original FAFSA. Some of the most common flags include a recent change of address, inconsistencies between earnings reported on taxes versus what was reported on the FAFSA, and if your family did not file taxes at all for the tax year being reviewed.
There is no way to completely avoid getting flagged, some schools flag all of their students for verification and others simply choose at random.
