In most cases, you do not have to pay student loans while you are in school. Federal student loans are automatically placed in deferment as long as you’re enrolled at least half-time, so no monthly payment is due until after you graduate, withdraw, or drop below that threshold. The two big exceptions are Parent PLUS Loans, which require a separate deferment request, and private student loans, which follow whatever your loan agreement says.
Federal Loans Pause Automatically
If you have Direct Subsidized, Direct Unsubsidized, or Grad PLUS Loans, your servicer places them into in-school deferment once your school confirms you’re enrolled at least half-time at an eligible college or career school.1Federal Student Aid. Student Loan Deferment You don’t file anything. The school reports your enrollment, the servicer updates your account, and no payment is required.
Half-time is defined by your school, not by a single federal credit-hour rule.2Federal Student Aid. Half-time Enrollment On a typical undergraduate semester schedule, that’s often six credit hours, but confirm the number with your registrar. Deferment generally continues through summer breaks and gaps between terms as long as you were enrolled at least half-time the prior year and plan to return.
If your enrollment is active but your account still shows a payment due, start with the school. The registrar can report or correct your enrollment so the servicer can apply the deferment.1Federal Student Aid. Student Loan Deferment
Parent PLUS Loans Are the Federal Exception
Parent PLUS Loans don’t get automatic deferment. A parent borrower has to submit a deferment request form to the servicer. To qualify, the loan must have been first disbursed on or after July 1, 2008, and the student must still be enrolled at least half-time at an eligible school.3Federal Student Aid. Parent PLUS Borrower Deferment Request
Without that request, payments on a Parent PLUS Loan begin right after the final disbursement. There is no built-in grace period.4Aidvantage – Federal Student Aid.

Private Student Loans Follow Your Contract
Private lenders set their own terms, and those terms vary. Whether you owe payments while in school depends on the promissory note you signed. Common in-school structures include:
- Full deferment, with repayment starting after a post-enrollment grace period.
- Interest-only payments each month, which keep the principal from growing.
- A small fixed monthly payment covering some combination of interest and principal.
Some lenders let you pick among these when you first borrow; others assign one. Read the loan agreement, and if the structure isn’t clear, ask the lender. Private loan deferment is a contractual benefit, not a legal right, so terms can differ between loans issued by the same company.
Interest Still Builds While You’re Enrolled
Not owing a payment isn’t the same as not owing interest. What you accrue during school depends on which loan type you have.
On Direct Subsidized Loans, the federal government covers the interest that accrues while you’re enrolled at least half-time.1Federal Student Aid. Student Loan Deferment Your balance stays where it started.
On Direct Unsubsidized Loans, Grad PLUS Loans, and Parent PLUS Loans, interest is yours to carry. It begins accruing the day the loan is disbursed.1Federal Student Aid. Student Loan Deferment If you don’t pay that interest as it accrues, the servicer eventually adds it to your principal. That’s called capitalization, and once it happens, future interest is calculated on the new, higher balance.5Federal Student Aid. Repaying Your Loans Over a four-year enrollment plus a grace period, that can meaningfully increase what you repay.
Should You Pay Anyway?
You’re allowed to make payments during school even when none are required, and federal student loans have no prepayment penalty. Two reasons to consider it:
Paying the interest as it accrues on unsubsidized or PLUS loans prevents capitalization, which keeps your principal from growing. Anything beyond interest goes toward the principal itself and shrinks the base that future interest is calculated on. Even $25 or $50 a month adds up across a degree.
Interest you pay may also be deductible. You can deduct up to $2,500 of student loan interest on your federal tax return, on both federal and qualified private loans, without itemizing.6Internal Revenue Service. Student Loan Interest Deduction The deduction phases out at higher incomes; for 2025, the phaseout range is $85,000 to $100,000 for single filers and $170,000 to $200,000 for joint filers, and the deduction isn’t available to anyone filing married filing separately.7Internal Revenue Service.

If Your Federal Loans Don’t Show as Deferred
Sometimes the automatic process breaks down. A school transfer, a delayed enrollment report, or a switch in servicer can leave your account showing a payment due when you’re actually enrolled. You can file the In-School Deferment Request form yourself through your servicer’s website or StudentAid.gov. You’ll need your Social Security number, your servicer’s contact information, your school’s OPEID code, the enrollment start and end dates, the school’s full name, and a certification signature from your registrar.
Submit the signed form through the servicer’s online portal, by mail, or by fax.8StudentAid.gov. In School Deferment Request Standard processing runs about 10 business days, and many online submissions clear within 24 hours.9Nelnet – Federal Student Aid. FAQ – Deferment and Forbearance If a payment is due before the deferment posts, ask the servicer about a temporary forbearance so the account doesn’t go delinquent.
What Changes When School Ends
Your in-school deferment ends the day you graduate, withdraw, or drop below half-time. Direct Subsidized and Direct Unsubsidized Loans then enter a six-month grace period before the first payment is due, and interest keeps accruing on unsubsidized balances during that grace.4Aidvantage – Federal Student Aid. In Your Grace Period10Federal Student Aid. Borrower In Grace Parent PLUS Loans and Direct Consolidation Loans do not come with a grace period; payments start right after the final disbursement unless a deferment is in place.
If you drop below half-time briefly and then re-enroll at half-time or more before the grace period runs out, the deferment should pick back up. Reporting delays can cause a lag, so check your servicer account after any enrollment change and follow up if the status hasn’t updated within a few weeks.
