In-school deferment for federal student loans lets you pause monthly payments while you’re enrolled at least half-time at an eligible school, with no cap on how long the pause lasts as long as your enrollment continues. The government pays the interest on Direct Subsidized Loans during that time. On unsubsidized and PLUS loans, interest keeps piling up, and that changes the math on whether pausing is actually the right move for you.
Who Qualifies
You need to be carrying at least half the normal full-time course load at an eligible school, using that school’s own definition of half-time.1eCFR. 34 CFR 685.204 – Deferment For most undergraduate programs measured in credit hours, half-time means at least six credits per term.2Federal Student Aid. Enrollment Status Minimum Requirements Graduate programs set their own credit or research thresholds. Your school’s financial aid office or registrar makes the final call.
An eligible school is any postsecondary institution that participates in the Title IV federal student aid programs. That covers most community colleges, public and private universities, and many for-profit institutions. Foreign schools qualify if the Department of Education has designated them as “Eligible” or “Deferment Only.” A “Deferment Only” designation lets you pause existing federal loan payments while enrolled, but you can’t borrow new federal loans through that school.3Federal Student Aid. Foreign School Frequently Asked Questions – Students A foreign school with neither designation doesn’t qualify at all.
One exclusion trips people up: medical interns and residents are not eligible for in-school deferment, with a narrow exception for dentistry residencies.1eCFR. 34 CFR 685.204 – Deferment Medical residents have other repayment options, but this isn’t one of them.
Which Loans Are Covered
In-school deferment applies to Direct Subsidized Loans, Direct Unsubsidized Loans, and Direct PLUS Loans.4Federal Student Aid. In-School Deferment Federal Perkins Loans also qualify if you still carry a balance; the Perkins program stopped issuing new loans after 2017.5Federal Student Aid. FSA Handbook – Perkins Repayment Plans, Forbearance, Deferment, Discharge, and Cancellation
Older FFEL Program loans (Federal Stafford and FFEL PLUS) can also be deferred, but the rules vary by disbursement date. FFEL loans first disbursed before July 1, 1987, generally require full-time enrollment rather than half-time, and consolidation loans add their own wrinkles. If you have older FFEL debt and you’re heading back to school, call your servicer before assuming your enrollment will trigger a deferment.
There’s No Time Limit
Unemployment and economic hardship deferments are capped at a combined three years. In-school deferment isn’t capped at all.6eCFR. 34 CFR 685.204 – Deferment As long as you stay enrolled at least half-time at an eligible school, the deferment continues. Someone who moves from a bachelor’s straight into a master’s and then a doctorate can stay in deferment the whole way through. The catch is what happens to the interest on unsubsidized loans over all those years.
How Interest Works While You’re Deferred
On Direct Subsidized Loans, the federal government pays the interest during in-school deferment. You won’t owe a cent more than you borrowed on those loans when the deferment ends.
Direct Unsubsidized Loans and Direct PLUS Loans don’t get that treatment. Interest accrues from the day of disbursement and keeps growing right through deferment. You can make interest-only payments to keep the balance flat, but most borrowers don’t.
Unpaid interest gets added to your principal when the deferment ends, a process called capitalization. From that point forward, you’re paying interest on interest. A concrete example: a $10,000 unsubsidized loan sitting through a six-month deferment might accumulate about $340 in interest. After capitalization, your new principal is $10,340, and every future interest calculation runs off that higher number. Stretched over several years of graduate school, the effect compounds meaningfully.
How the Deferment Gets Applied
Automatic Through Enrollment Reporting
Most borrowers never file anything. Schools report enrollment status to the National Student Loan Data System on a regular schedule.7Federal Student Aid Partners. NSLDS Enrollment Reporting Guide – February 2026 Once the system shows you enrolled at least half-time, your loan servicer applies the deferment automatically and notifies you, giving you the option to cancel if you’d rather keep paying.5Federal Student Aid. FSA Handbook – Perkins Repayment Plans, Forbearance, Deferment, Discharge, and Cancellation
Reporting happens on a schedule, not in real time, so there can be a gap between the first day of classes and the day the deferment shows up on your account. Keep making payments during that gap. If a payment turns out to have been unnecessary, you can request a refund or ask the servicer to apply it to principal.
Filing the Request Manually
When automatic reporting doesn’t kick in, submit the In-School Deferment Request form (OMB No. 1845-0011) to your loan servicer. It asks for your Social Security Number, current address, the school’s name, and its Office of Postsecondary Education Identification code. An authorized school official, usually in the registrar’s office, has to complete a section certifying your enrollment status and dates.8Federal Student Aid. In-School Deferment Request The form is on StudentAid.gov or available directly from your servicer.
Servicers generally process manual requests within about 10 business days. You’re still responsible for payments until you get written confirmation showing the approved start and end dates. Watch your account during that window so a late fee doesn’t slip through.
A deferment can be applied retroactively, but the retroactive period can’t begin more than six months before the date your servicer receives the request.9Federal Student Aid. Grace Periods, Deferment, and Forbearance in Detail If you were enrolled months ago and never got the deferment applied, the longer you wait, the more of that past enrollment you lose.
When You Should Turn Deferment Down
Pausing payments sounds like a straightforward win. For some borrowers, it isn’t.
If you’re on an income-driven repayment plan working toward 20- or 25-year forgiveness, months spent in in-school deferment don’t count toward that timeline.10Federal Student Aid. Payment Count Adjustments Toward Income-Driven Repayment and Public Service Loan Forgiveness Every semester in deferment is a semester that doesn’t get you closer to forgiveness. If you’re already several years into an IDR plan and heading back to school part-time, staying in repayment on a $0 or low-dollar IDR payment may serve you better than the automatic pause.
The same logic applies to Public Service Loan Forgiveness. Only qualifying payments made while working for an eligible employer count toward the 120-payment threshold. Deferment months produce zero qualifying payments. A borrower working full-time for a qualifying employer while attending graduate school part-time is often better off staying in active repayment.
To opt out, tell your servicer you want to cancel the in-school deferment.4Federal Student Aid. In-School Deferment You have to do this yourself; the automatic process applies deferment without asking.
Parent PLUS Loans Follow a Separate Path
If a parent borrowed a Direct PLUS Loan for a child’s education and it was first disbursed on or after July 1, 2008, the parent can defer payments while the student is enrolled at least half-time, plus an additional six months after the student graduates, withdraws, or drops below half-time.11Federal Student Aid. Parent PLUS Borrower Deferment Request
This one isn’t automatic. Parents have to submit the Parent PLUS Borrower Deferment Request form and specifically check the box for the six-month post-enrollment deferment. Interest accrues the whole time and capitalizes when the deferment ends, so interest-only payments during the pause save money over the life of the loan.
Graduate Fellowship Deferment Is Its Own Category
Full-time graduate fellowships get a separate deferment even when the fellowship doesn’t look like traditional enrollment. You need a bachelor’s degree, a fellowship providing financial support for at least six months of full-time study, and a program that requires periodic progress reports or projects.12Federal Student Aid. Graduate Fellowship Deferment Request It uses its own form, not the standard in-school request. If your fellowship involves study at a foreign university, that coursework has to count toward completing the fellowship.
What Happens When You Leave School
When you graduate, withdraw, or drop below half-time, the deferment ends and a six-month grace period begins for most Direct Loans. The grace period starts the day after you drop below half-time enrollment and ends the day before your repayment period begins.9Federal Student Aid. Grace Periods, Deferment, and Forbearance in Detail
Short breaks in enrollment don’t burn up the grace period. If you sit out a semester and re-enroll at least half-time, the full six months is still there when you actually finish. Interest on unsubsidized loans keeps accruing during the grace period and capitalizes when repayment starts.
Tell your loan servicer promptly if you drop below half-time or withdraw. Schools do report enrollment changes to the National Student Loan Data System, but reporting gaps can cause confusion, and payments may come due unexpectedly once the data catches up, sometimes with retroactive interest charges. When the grace period ends, your servicer sends a repayment schedule with your first due date and monthly amount.
