Yes, you have to pay back federal subsidized loans. The government covers the interest while you’re in school, during your six-month grace period, and during authorized deferments, but the principal is yours to repay from the day you sign, and interest that accrues after those windows is yours too. How much you ultimately pay depends on the repayment plan you pick, whether you qualify for forgiveness or discharge, and whether you stay current.
What You Agreed to When You Signed
Your obligation begins with the Master Promissory Note. Signing it is a legally binding promise to repay every loan disbursed under it, plus interest and any fees.1Federal Student Aid. Master Promissory Note (MPN) Direct Subsidized Loans and Direct Unsubsidized Loans A single MPN can cover up to ten years of borrowing, so each new disbursement piles onto the same promise.
Federal regulations spell out that you owe the full principal, fees, collection costs, and any unsubsidized interest.2eCFR. 34 CFR Part 685 Subpart B – Borrower Provisions – Section: 685.207 Obligation to Repay That obligation stands whether or not you finish your degree, and whether or not the education paid off. The only real exits are the forgiveness and discharge programs described below.
When the Government Pays the Interest and When You Do
The “subsidized” label refers to interest, not principal. The Department of Education pays the interest on your behalf during three windows:
- While you’re enrolled at least half-time
- During your six-month grace period after you leave school or drop below half-time
- During authorized deferments, such as unemployment or economic hardship
During those periods, your balance holds flat instead of growing.2eCFR. 34 CFR Part 685 Subpart B – Borrower Provisions – Section: 685.207 Obligation to Repay Outside them, interest accrues and is yours to pay.
Forbearance Is Not Deferment
Borrowers often confuse the two. During forbearance, interest keeps accruing on subsidized loans and you owe it.3Federal Student Aid. What Is the Difference Between Loan Deferment and Loan Forbearance If you don’t pay it, it can capitalize onto your principal, so you end up paying interest on interest. Deferment preserves the subsidy; forbearance does not.
The 150% Limit
Your subsidy has a clock. You can only receive subsidized loans for up to 150% of the published length of your program, which works out to six academic years for a standard four-year bachelor’s degree.4Federal Student Aid. Time Limitation on Direct Subsidized Loan Eligibility If you cross that line and stay enrolled, you lose the interest subsidy on your existing subsidized loans going forward. Interest you thought was covered starts falling on you. Changing majors or taking longer than expected to finish can trigger this without warning.
When Repayment Starts
When you graduate, leave school, or drop below half-time, a six-month grace period starts automatically. No payments are due, and the government keeps paying your interest.2eCFR. 34 CFR Part 685 Subpart B – Borrower Provisions – Section: 685.207 Obligation to Repay Your first payment comes due within 60 days after the grace period ends.
You get one grace period per loan. If you use it, re-enroll, and leave again, it does not reset. The one exception is military service. Active duty of more than 30 days is excluded from the grace period for up to three years, and you get time to re-enroll before the clock resumes.5eCFR. 34 CFR 685.207 – Obligation to Repay
How Much You’ll Pay Each Month
If you don’t pick a plan, you land on the Standard Repayment Plan by default. It sets fixed monthly payments aimed at paying the loan off in ten years.6eCFR. 34 CFR 685.208 – Fixed Payment Repayment Plans It’s the cheapest in total interest and the highest in monthly cost.
Income-Driven Repayment
If your income is modest relative to your debt, an income-driven repayment (IDR) plan bases your monthly payment on a percentage of your discretionary income. Options include Income-Based Repayment, Pay As You Earn, and Income-Contingent Repayment. Payments run from 10% to 20% of discretionary income depending on the plan and when you borrowed, and a low enough income can drop your payment to zero while still counting toward eventual forgiveness.7eCFR. 34 CFR 685.209 – Income-Driven Repayment Plans
The menu is in flux. The SAVE Plan is no longer accepting new enrollees after the Department of Education reached a settlement to end the program following extended court challenges. Borrowers who were on SAVE have been placed in forbearance while being transitioned to other plans.8Federal Student Aid. Income-Driven Repayment Court Actions Before choosing an IDR plan, ask your servicer which options are actually open to you right now.
After enough qualifying payments on an IDR plan, any remaining balance is forgiven. On IBR for borrowers who took their first loan after July 1, 2014, and on PAYE, that’s 20 years. On IBR for borrowers before that date, and on ICR, it’s 25 years.
Ways Your Balance Can Be Wiped Out
Public Service Loan Forgiveness
If you work full-time for a government agency, a 501(c)(3) nonprofit, or another qualifying public-service employer, Public Service Loan Forgiveness cancels your remaining balance after 120 qualifying monthly payments, roughly ten years.9eCFR. 34 CFR 685.219 – Public Service Loan Forgiveness Program (PSLF) Full-time means averaging at least 30 hours per week, and you can combine part-time qualifying jobs to get there.
The payments have to be made under a qualifying repayment plan while you’re at a qualifying employer, and you have to be employed full-time by a qualifying employer both when you make the 120th payment and when you submit the application.9eCFR. 34 CFR 685.219 – Public Service Loan Forgiveness Program (PSLF) Late or partial payments generally do not count. This is where most PSLF applications trip up: borrowers assume payments counted when they didn’t, because the plan was wrong, the payment was late, or the employer wasn’t qualifying at the time.
Teacher Loan Forgiveness
Full-time teachers who complete five consecutive years at a low-income school can get up to $17,500 forgiven on their Direct Subsidized and Unsubsidized Loans. The $17,500 maximum goes to highly qualified secondary math and science teachers and to special education teachers; other eligible teachers qualify for up to $5,000.10Federal Student Aid. 4 Loan Forgiveness Programs for Teachers It’s a dollar cap, not a full-balance cancellation.
Discharge in Extreme Circumstances
Certain situations cancel the loan outright:
- Death of the borrower, on submission of a death certificate or verification through an approved database. For a Parent PLUS Loan, the student’s death also triggers discharge.11eCFR. 34 CFR 685.212 – Discharge of a Loan Obligation
- Total and permanent disability that leaves you unable to work.11eCFR. 34 CFR 685.212 – Discharge of a Loan Obligation
- Closure of your school while you’re enrolled or shortly after you withdraw.11eCFR. 34 CFR 685.212 – Discharge of a Loan Obligation
- Borrower defense to repayment if your school engaged in substantial misrepresentation, fraud, or aggressive and deceptive recruiting tied to your loan.
Payments made after you became eligible for one of these discharges are returned to you or to your estate.
The Tax Bill on Forgiven Balances
Forgiveness is not always free. The American Rescue Plan Act’s temporary exclusion of forgiven student debt from taxable income expired on January 1, 2026, so balances forgiven under IDR plans are generally treated as taxable income at the federal level again.12NASFAA. Welcome to 2026: Some Student Loan Forgiveness Is Now Taxable If $30,000 gets forgiven after 20 years on IBR, you could owe federal income tax on that amount as if you’d earned it.
Two exceptions matter. Forgiveness under PSLF and Teacher Loan Forgiveness remains tax-free. Discharges for death, total and permanent disability, closed school, and borrower defense are also excluded from taxable income.
If IDR forgiveness leaves you with a tax bill and your debts exceed your assets at the time of forgiveness, the insolvency exclusion may apply. You’d file Form 982 and exclude up to the amount by which you were insolvent.13Internal Revenue Service. Publication 4681, Canceled Debts, Foreclosures, Repossessions, and Abandonments It won’t rescue borrowers who’ve built assets by year 20 or 25, but for someone still struggling financially, it can cut or erase the tax.
What Happens If You Stop Paying
Missing payments on a federal loan triggers a predictable sequence. At 90 days late, the servicer reports the delinquency to the three major credit bureaus. At 270 days without payment, the loan goes into default.14Federal Student Aid. Student Loan Default and Collections: FAQs
Default unlocks collection tools that don’t require a court order. The Department of Education can take up to 15% of your disposable pay through administrative wage garnishment.15Federal Student Aid. Collections on Defaulted Loans It can intercept federal tax refunds through the Treasury Offset Program.16U.S. Department of Education. U.S. Department of Education to Begin Federal Student Loan Collections, Other Actions to Help Borrowers Get Back into Repayment For Social Security recipients, up to 15% of benefits above $750 per month can be offset.17Consumer Financial Protection Bureau. Issue Spotlight: Social Security Offsets and Defaulted Student Loans Collection costs are added to your balance, and you lose access to more federal aid, deferment, and forbearance.
Federal student loans almost never go away on their own. Unlike credit cards or medical bills, they generally cannot be discharged in bankruptcy, and the statute of limitations on collection does not expire for most of them. If the payments have become impossible, switching to an income-driven plan with a zero-dollar payment is almost always a better move than not paying.
