This means that both the 2016-17 and 2017-18 FAFSA's require the same tax information. In some cases, if discrepancies are present between the tax information in these two year the Department of Education may require universities to fully review both of these applications, regardless of how long ago they were originally completed. This is called a 399 c-flag or c-code. At UMUC we may also refer to this as a prior-prior year discrepancy or PPY.
If your FAFSA is selected for this review we will work with you to let you know what is needed. It is of utmost importance that you quickly follow-up with any requests as eligibility may change because of this review as we correct the accuracy of the information originally provided.
