Cosigning for student loans
Most federal student loans never involve a cosigner, while most private ones do, and the 2026 changes to federal borrowing limits are pushing a new wave of parents, relatives, and friends toward the private side of the ledger.
Why it matters: A cosigner is a co-borrower, not a reference
A cosigner is not a reference or a backup, but a second borrower with the same legal obligation, and the rules for getting out of that obligation, or for what happens if the student dies or goes bankrupt, depend entirely on whether the loan is federal or private.

How Co-Borrowing Differs Across Loan Types
Cosigning rules depend entirely on whether the debt is direct federal, federal PLUS, or private.
| Feature / Rule | Direct Federal LoansSubsidized & Unsubsidized | Direct PLUS LoansParent PLUS & Legacy Grad PLUS | Private Student LoansBanks, Credit Unions & Online Lenders |
|---|---|---|---|
| Cosigner required? | Never. Students qualify independently. | Only if primary applicant has adverse credit. | Required for >90% of undergraduate/thin-file applicants. |
| Credit check criteria | None. No credit history check. | Adverse credit check only (no score minimum; thin file passes). | Strict credit score and income underwriting. |
| Co-signer legal term | N/A (No co-signer permitted or needed) | Endorser (must complete addendum on StudentAid.gov) | Cosigner (equally legally liable co-borrower) |
| Impact on cosigner's credit | None | Pursued only if primary borrower defaults or falls behind | Appears on credit report immediately; raises DTI ratio |
| Discharge upon death | Discharged on borrower death | Discharged if parent or student dies; endorser death does not cancel debt | Mandatory cosigner release on student death (loans post-Nov 20, 2018) |
| Exit / release option | N/A | No release process exists; endorser remains bound | Conditional release after 12–48 months, or solo private refinance |
The basic rule: federal loans mostly don't use cosigners
- Direct Subsidized and Unsubsidized Loans, the federal loans most undergraduates use, require no cosigner, and neither one checks credit, whether the borrower is an undergraduate or a graduate student, so a student with no credit history qualifies on their own.
- The only federal loans that check credit are Direct PLUS Loans.
- The test is not a credit score, since the Department of Education looks for a defined list of negative events, such as a recent bankruptcy discharge, repossession, foreclosure, or serious delinquencies, rather than ranking applicants by score.
- Having no credit history at all is not treated as adverse credit, so a thin file alone will not disqualify a PLUS applicant.
- The federal word for a cosigner is endorser, and it applies only when a PLUS applicant fails the credit check and chooses to add an endorser rather than appeal.
How a federal endorser works
- An endorser must agree to repay the PLUS loan if the borrower does not, must not have an adverse credit history of their own, and must be an adult U.S. citizen or permanent resident.
- The endorser completes an addendum online at studentaid.gov, and the borrower must also finish PLUS credit counseling before any money is released.
- A student cannot serve as the endorser on a parent's loan for that same student, which rules out the obvious shortcut.
- Endorsers do not get all of a borrower's benefits, and an endorser cannot consolidate the loan they endorsed, which limits how they can restructure it later.
- The arrangement is specific to the loan it was signed for, so a borrower who needs another PLUS loan later and fails the credit check again needs a new endorser agreement.
- The risk is real: if the borrower falls behind, the servicer will pursue the endorser for payment.
- There is a second route that needs no endorser at all, which is to appeal the credit decision by documenting that the credit report is wrong or that extenuating circumstances caused the negative item.
- If a parent is denied a Parent PLUS loan, the student can request additional Direct Unsubsidized Loan eligibility for that year, which needs no cosigner.
Parents with a past bankruptcy, foreclosure, or collection account who want to borrow for a child, and graduate students who already hold a Grad PLUS loan and need to keep borrowing under the legacy provision.
What changed for federal PLUS loans in 2026
- Since July 1, 2026, Grad PLUS loans have been eliminated for new borrowers, which means the endorser route for graduate students survives only for those covered by the legacy provision.
- Parent PLUS loans are now capped at $20,000 per student per year and $65,000 per student in total, a limit that applies per student rather than per parent, so two parents borrowing for one child share the same ceiling.
- Parents who borrowed before July 1, 2026 keep the old limits for up to three more years or until the student's program ends, which softens the cliff for current families.
- A new Parent PLUS loan taken out after that date can be repaid only under the tiered standard plan, and taking out any new federal loan after that date removes income-driven repayment eligibility from all of the parent's PLUS loans, which matters to any endorser backing the loan.
- New graduate borrowing is limited to $20,500 per year and $100,000 in total, or $50,000 per year and $200,000 in total for designated professional programs.
How private student loan cosigning works
- Private lenders judge a student's credit and income, and because most students have thin credit files and little income, the lender often approves the loan only on the strength of a cosigner's credit.
- The cosigner is equally legally responsible for the debt, the loan appears on the cosigner's credit report, and late payments by the student damage the cosigner's credit as well.
- A cosigner can also lower the interest rate, and even a student who qualifies alone may receive a better offer by applying with a creditworthy cosigner.
- Private loans are missing the federal safety net, since lenders typically do not offer income-driven repayment or forgiveness, and many charge variable rates.
- Cosigned debt can crowd out a cosigner's other borrowing, because it counts toward their debt-to-income ratio when they apply for a mortgage, a car loan, or a refinance.
Getting a cosigner off the loan
Cosigner release lets a lender remove the cosigner after the borrower makes a set number of consecutive on-time payments and qualifies on their own credit and income.
The payment streak ranges from 12 to 48 months depending on the lender, with Sallie Mae and SoFi at 12 payments, Navy Federal at 24, Citizens at 36, and MEFA at 48.
| Lender | Required Payment Streak | Requirements & Notes |
|---|---|---|
| Sallie Mae | 12 consecutive payments | Full principal & interest; borrower must pass solo credit and income underwriting. |
| SoFi | 12 consecutive payments | Continuous on-time full payments; primary borrower must meet credit criteria. |
| Navy Federal Credit Union | 24 consecutive payments | Two full years of flawless on-time payments with solo credit qualification. |
| Citizens Bank | 36 consecutive payments | Three full years of payments; stringent income and credit re-evaluation. |
| MEFA | 48 consecutive payments | Four full years of on-time payments required before release is considered. |
- Payments generally must be full principal and interest, so interest-only payments or reduced payments during a hardship plan do not count toward the streak.
- Release is a privilege, not a right, and lenders are not required by law to offer it or to approve it.
- The CFPB reported in 2015 that lenders rejected 90% of applications, often because borrowers did not meet unstated pre-application requirements, and found that lenders rarely told borrowers when they became eligible, as described in the agency's report.
- Using a lender's forbearance can permanently bar a borrower from release on some loans, according to the same report.
- The more reliable exit is to refinance the loan into the borrower's name alone once their credit and income allow it, which replaces the old loan entirely.
Between the lines: Most federal loans have nothing to release, since there is no cosigner in the first place, and the Department of Education's endorser rules describe no release process, so a PLUS endorser should assume they stay responsible until the loan is repaid or discharged.
What happens if someone dies, defaults, or files for bankruptcy
- A federal loan is discharged when the borrower dies, and a Parent PLUS loan is discharged if either the parent or the student dies, but an endorser's death alone does not cancel the debt.
- Private lenders are not required to cancel a loan when the borrower dies, although some do, and for private loans made on or after November 20, 2018, federal law requires the lender to release the cosigner when the student dies.
- Before that, many contracts contained “auto-default” clauses that demanded full repayment if a cosigner died or filed for bankruptcy even when the loan was current, and the same 2018 law bars lenders from declaring default solely for that reason on loans made on or after November 20, 2018.
- Tax law now excludes student debt discharged because of the student borrower's death from income for discharges after December 31, 2025, so the canceled amount is not taxed as income.
- A borrower's bankruptcy does not release the cosigner, because federal bankruptcy law says a discharge does not affect anyone else liable on the same debt, and a filing can accelerate the full balance against the cosigner.
- Older contracts, signed before November 20, 2018, may still trigger default on a cosigner's death, so it is worth reading the promissory note and asking the lender about replacement or release options early.
Why more families are being asked to cosign now
- With Grad PLUS gone and federal caps in place, the Department of Education's own limits are pushing students above the cap toward private lenders, and higher education expert Mark Kantrowitz estimated private student loan volume could rise by as much as 85%, nearly doubling, as the new limits phase in.
- Private lenders will not generally replace lending to students with thin or poor credit, according to a 2026 American Enterprise Institute primer, which noted that Grad PLUS reached borrowers without cosigners.
- An analysis by the Federal Reserve Bank of Philadelphia and American University's PEER Center found that among affected graduate borrowers, nearly 4 in 10 have a subprime credit score or no credit history at all, which makes a private loan hard to get without a cosigner.
- The new Parent PLUS cap also leaves a gap for families whose costs exceed $65,000 per student, and filling it with private borrowing is where a cosigner is the norm.
Questions to ask before signing
Check off each critical term before agreeing to cosign or endorsing any loan application:
1. Cosigner release terms in writing
Ask for the lender's cosigner release terms in writing, including the payment count, credit score, and income thresholds, and whether forbearance affects eligibility.
2. Death and disability discharge policy
Ask whether the loan is discharged on the borrower's death or disability, and whether it is released from the cosigner on the student's death.
3. Immediate online account access for the cosigner
Ask for the cosigner to have online access to the account, so they see missed payments immediately instead of learning of them from a collector.
4. Exhaust all federal borrowing options first
Compare against the federal options first, since a federal loan needs no cosigner, carries repayment and discharge protections, and can leave a family's credit untouched.
5. Verify rate type and budget for the worst case
Check the rate type and budget for the worst case, since a variable rate can rise and the cosigner is the one who pays if the student cannot.
A cosigner is a full borrower in everything but name
A cosigner on a private loan, or an endorser on a PLUS loan, is a full borrower in everything but name, so the decision should rest on whether the cosigner could afford the entire loan and whether the lender's exit terms, and not just its rate, are clear before anything is signed.
