Many doctors are enrolled in an income driven repayment plan like IBR or REPAYE which offers loan forgiveness after 25 years but then taxes the forgiven debt as income.
PSLF will erase your entire student debt and interest, tax-free, a full 15 years faster than the income driven repayment plans!
Not currently on an income driven plan? PSLF could still save you 6 figures on your student loans.
