Such qualifying repayment plans include all the income-driven repayment plans that use your income to figure out your payment.
If my payments under the 10-year Standard Repayment Plan are qualifying payments is there anything else I could do to benefit?
You would need to change to an income driven repayment plan to benefit from PSLF because your loans will be paid in full once you have made 120 qualifying PSLF payments and there will be no balance to forgive.
Who would I contact for more questions?
