About Income-Driven Repayment (IDR)

Income-Driven Repayment plans set federal student loan payments based on household income and family size rather than total outstanding debt balance.

Discretionary Income Calculation

Discretionary Income = AGI - (1.5 × Federal Poverty Guideline)

Monthly payment is calculated as either 10% or 15% of discretionary income divided by 12.

Frequently Asked Questions

What happens to remaining debt after 20 or 25 years?

Remaining loan balances are eligible for discharge after 20 to 25 years of qualifying monthly payments, depending on the specific IDR plan and undergraduate versus graduate debt mix.

Do zero-dollar payments count toward forgiveness?

Yes. If income falls below the federal poverty threshold, calculated monthly payments of $0 count toward loan forgiveness requirements.

How often must income be recertified?

Borrowers must recertify income and family size annually to maintain their calculated monthly payment tier.

Is forgiven student loan debt federally taxable?

Tax treatment depends on current federal legislation; verify applicable rules with a tax advisor when planning long-term forgiveness strategies.
