What Is Income-Driven Repayment for Student Loans?
Updated July 9, 2026 · SmartRates Editorial Team
⚡ In short
Income-driven repayment (IDR) is a category of federal student loan repayment plans that calculate the monthly payment as a percentage of a borrower's discretionary income, rather than a fixed amount based on loan balance and term. The US Department of Education offers several IDR plans, each with its own payment formula and loan-forgiveness timeline after a set number of qualifying payments — current plan details are listed on studentaid.gov.
📌 Key facts
- IDR plans require annual recertification of income and family size
- Remaining balances on IDR plans may be forgiven after a set number of years of qualifying payments, as defined by each specific plan
- IDR plans are available only for federal student loans, not private loans
- Historically offered IDR plans have included Income-Based Repayment (IBR) and Pay As You Earn (PAYE), among others — current availability should be confirmed on studentaid.gov

How the payment is calculated
IDR plans calculate a monthly payment as a percentage of discretionary income, generally defined as income above a threshold tied to the federal poverty guidelines for the borrower's family size and state. The specific percentage and discretionary-income definition vary by plan, and the calculation uses adjusted gross income as reported on the borrower's most recent federal tax return, or self-reported income for borrowers who don't have a recent return on file.
Available federal IDR plans
The Department of Education has offered multiple IDR plans over time, including Income-Based Repayment (IBR) and Pay As You Earn (PAYE), among others, each with its own payment formula and forgiveness timeline. Because plan availability and terms have changed through legislation and litigation, the current list of active IDR plans is maintained on studentaid.gov. Eligibility for a specific IDR plan can depend on when the underlying loan was originated and the loan type, so not every plan is available to every federal borrower.
Recertification requirement
Borrowers on an IDR plan are generally required to recertify their income and family size annually, since the monthly payment is recalculated based on updated information each year. Failing to recertify by the deadline can result in the borrower being moved to a different payment calculation, sometimes based on the standard 10-year plan amount, until updated income information is provided.
Loan forgiveness after the repayment period
IDR plans generally forgive any remaining loan balance after a set number of years of qualifying payments, as defined by the specific plan. Federal and state tax treatment of forgiven IDR balances has varied by year and by plan, and should be confirmed for the relevant tax year.
Applying for an IDR plan
Borrowers apply for an IDR plan directly through studentaid.gov or through their loan servicer, providing income and family size documentation as part of the application. A borrower can generally switch between different repayment plans, including moving into or out of an IDR plan, subject to eligibility rules for the specific plan being requested.
How married borrowers' income is counted
For a married borrower, some IDR plans calculate the payment using only the borrower's individual income, while others factor in a spouse's income as well, depending on the specific plan and how the couple files their federal tax return (jointly or separately). This distinction can materially change the calculated payment amount for married borrowers and is one of the ways the specific IDR plan chosen affects the outcome beyond just the borrower's own income figure.
Public Service Loan Forgiveness as a related but separate program
Public Service Loan Forgiveness (PSLF) is a separate federal forgiveness program from standard IDR forgiveness, available to borrowers employed by qualifying government or nonprofit organizations who make a set number of qualifying payments, often while enrolled in an IDR plan. PSLF has its own eligibility rules, employer certification requirements, and forgiveness timeline, distinct from the standalone forgiveness that occurs at the end of an IDR plan's repayment period for borrowers not pursuing PSLF.
How IDR compares to the standard repayment plan structurally
The standard federal repayment plan sets a fixed payment calculated to pay off the loan over 10 years, regardless of the borrower's income. An IDR plan, by contrast, ties the payment to income and can extend the repayment period well beyond 10 years — often 20 or 25 years, depending on the plan — with any remaining balance forgiven at the end of that period rather than continuing indefinitely.
Frequently Asked Questions
Is income-driven repayment available for private student loans?+
No. IDR plans are a federal program available only for federal student loans — private lenders set their own repayment terms.
Does income-driven repayment require reapplying every year?+
Yes. Federal IDR plans require annual recertification of income and family size to keep the calculated payment current.
Does an IDR payment ever exceed the standard 10-year plan payment?+
IDR payment formulas are generally designed to be at or below the standard 10-year plan payment for a given income level, though the exact comparison depends on the specific plan and the borrower's income and family size.
What happens if a borrower misses the annual recertification deadline?+
Missing the deadline can result in the payment being recalculated using a different method, sometimes reverting to the standard 10-year plan amount, until updated income and family size information is submitted.
Where does a borrower apply for an income-driven repayment plan?+
Applications are submitted directly through studentaid.gov or through the borrower's loan servicer, with income and family size documentation required as part of the process.
Does an IDR plan's forgiven balance appear on a credit report differently than a paid-off loan?+
The loan is generally reported as paid or closed once forgiven, though the specific reporting details are determined by the servicer following standard credit bureau reporting practices for closed accounts.
Can a borrower be on an IDR plan for some federal loans and the standard plan for others?+
Loan servicers generally allow selecting a repayment plan on a per-loan or per-servicer-account basis, so a borrower with multiple federal loans is not necessarily locked into the same plan for all of them, subject to each loan's own eligibility.
Does consolidating federal loans affect IDR eligibility or the forgiveness timeline?+
Consolidating loans into a Direct Consolidation Loan can affect which IDR plans are available and can, in some cases, restart the qualifying-payment count toward forgiveness, depending on the specific consolidation and plan involved.
