According to the Department of Education, you can potentially receive forgiveness under both the TLF Program and PSLF Forgiveness Program, but not for the same period of teaching service.
For example, if you complete five consecutive years of qualifying teaching and receive partial forgiveness under the TLF, that would negate 5 years of qualifying PSLF credits during that same period.
To receive Public Service Loan Forgiveness on top of Teacher Loan Forgiveness, you would need to restart your accumulation of PSLF credits. For example, if you have Direct loans, are on an income-driven repayment plan, and continue working as a teacher, the fastest you could get forgiveness through both programs would be 15 years—5 years to earn partial forgiveness through Teacher Loan Forgiveness (as long as you’re meeting the necessary eligibility requirements for that program) and 10 additional years to qualify for Public Service Loan Forgiveness, which would eliminate the remaining balance on all qualifying loans.
Pursuing both forgiveness programs is not the best choice for all borrowers. For example, if you’re within a few years of completing the eligibility criteria for PSLF and have the prospect of having the balance on your outstanding loans forgiven, it may make more sense to stick with PSLF rather than pursuing TLF. The Savi tool also allows you to see the impact of either route on the total amount of student loans repaid and potential forgiveness amount to help you make the decision that best fits your financial goals.
