What buyback is
PSLF counts monthly payments. Months when your payments were paused by a deferment or forbearance that doesn’t count toward PSLF are gaps in your 120. Buyback lets you fill those months.
The rule
For months when you were in a non-qualifying deferment or forbearance and working full time for a qualifying employer, you can get PSLF credit by either:
- making an additional payment at least equal to what you would have owed then on a qualifying repayment plan, or
- showing you would have qualified for a $0 payment on an income-driven plan then (34 CFR 685.219).
When you can use it
StudentAid.gov says you can buy back months, including months in the SAVE forbearance, once you already have 120 months of qualifying employment.
The RAP exception
The buyback rule doesn’t apply to periods when you were repaying under RAP. On RAP, credit comes from on-time payments.
Planning
Buyback months shorten the remaining count. The PSLF calculator adds them to see what is left.
