The following borrowers can reapply or request an increase in their PPP loan amount: a. If a borrower returned all of a PPP loan, the borrower may reapply for a PPP loan in an amount the borrower is eligible for under current PPP rules. b. If a borrower returned part of a PPP loan, the borrower may reapply for an amount equal to the difference between the amount retained and the amount previously approved. c. If a borrower did not accept the full amount of a PPP loan for which it was approved, the borrower may request an increase in the amount of the PPP loan up to the amount previously approved. Any request for an increase must be submitted electronically in E-Tran on or before March 31, 2021, and is subject to the availability of funds. SBA will issue additional guidance on the process to reapply or request a loan increase under subsections D.6, D.7, and D.8. 9.
