Refinancing federal loans means losing:

  • Losing IDR income-driven repayment: payments tied to income (including the new RAP plan and IBR)
  • Losing PSLF: public service loan forgiveness after 120 payments
  • Losing federal deferment/forbearance: mandatory relief during economic hardship
  • Losing death/disability discharge: federal loans are discharged upon total disability or death

Student loan refinancing FAQs

Does refinancing federal student loans make them private?

Yes. A private lender pays off the federal loans and issues a new private loan. The new loan is no longer eligible for federal income-driven repayment, Public Service Loan Forgiveness, or federal deferment and discharge protections.

Is interest on a refinanced student loan still deductible?

Interest on a refinanced loan can remain qualified student loan interest when the original debt paid qualified higher-education expenses and the refinance proceeds are used only to refinance that debt. The deduction remains subject to IRS eligibility and MAGI limits.

Should I refinance if the private interest rate is lower?

A lower rate can reduce interest, but the comparison should value federal protections and any realistic forgiveness path. Borrowers pursuing PSLF or needing income-driven payments can lose more in benefits than the rate reduction saves.
