Every federal student loan borrower signs a Master Promissory Note (MPN), spends about four minutes on it, and never looks at it again.

With all the student loan changes, that’s borrowers question what they actually signed. Millions of borrowers are discovering that the repayment plan they counted on no longer exists, and a lot of them are going back to a document they signed years ago looking for a guarantee that isn’t in there.

The MPN is a contract, and it’s the single most important document in your student loan borrowing life. But it works differently than most people assume. It doesn’t set the rules in place on the day you sign — it points to federal law and moves when federal law moves.

Understanding that distinction is what separates borrowers who pick the right repayment plan from borrowers who get blindsided by a deadline.

Here’s what the MPN actually says, what can legally change, and what can’t.

What Are Master Promissory Notes?

A Master Promissory Note (MPN) is a legally binding document in which a federal student loan borrower promises to repay their loans, plus interest and fees, to the U.S. Department of Education. It’s the contract that sits underneath every federal loan you take out, and it’s the reason federal loans work so differently from private loans.

You have to sign an MPN before you can receive any federal student loan money. But you don’t sign a new one every year. A single MPN can cover multiple disbursements for up to 10 years, which is why most undergraduates sign once as a freshman and never think about it again.

There are three separate MPNs, and which one you sign depends on what you’re borrowing. 

If you signed an undergraduate MPN and later head to graduate school, you’ll sign a new one. And if you’re a parent borrowing for more than one child, you’ll generally sign a separate Parent PLUS MPN for each student, which is worth knowing before you compare Parent PLUS against the alternatives.

Attached to every MPN is the Borrower’s Rights and Responsibilities Statement (BRR). This is the part almost nobody reads, and it’s the part that matters most right now. Nearly everything in this article about what can and can’t change comes straight out of that document, which also happens to be the clearest statement of your rights as a federal borrower you’ll ever be handed.

What Does The MPN Contain?

Master Promissory Notes are dense, but a handful of sections do most of the work.

Interest rate and how interest is charged. Your rate is fixed for the life of each loan and set by your disbursement date, which is why the rate for each school year matters so much. It matters most for unsubsidized loans, which start accruing interest the day the money hits your account.

Borrowing limits. The One Big Beautiful Bill Act (OBBBA) reset these for loans first disbursed on or after July 1, 2026, and the new federal borrowing limits are meaningfully tighter than the old ones:

• Graduate students: $20,500 per year, $100,000 aggregate
• Professional students (medicine, law, and other qualifying programs): $50,000 per year, $200,000 aggregate
• Parent PLUS: $20,000 per student per year, $65,000 lifetime per student
• Overall lifetime cap across most federal student loans: $257,500

Students already enrolled and borrowing before July 1, 2026 generally get a grandfathering window (up to three additional years or until they finish their program, whichever comes first) provided they stay in the same program at the same school. Everyone else is looking at a gap that private student loans will have to fill.

Grace periods, deferment, and forbearance. The MPN spells out your grace period and the circumstances under which you can pause payments through deferment or forbearance.

Repayment terms. The MPN tells you when repayment starts and points you to the repayment plans available under the law. Note the wording — available under the law, not “available on the day you signed.” That single phrase explains most of what happened to borrowers in 2025 and 2026, including the SAVE plan’s collapse.

The Repayment Plan Section Doesn’t Work The Way People Think

This is the biggest misconception about MPNs, and it’s worth being blunt about it.

A common misconceptions is that because the MPN is a legally binding contract, signing it gave you a permanent, guaranteed right to income-driven repayment for the life of your loan. That was always an overstatement, and the last two years proved it.

SAVE is gone. PAYE and ICR are being phased out. New borrowers as of July 1, 2026 can’t access any of them, because the Education Department finalized a two-plan system. If the MPN really locked in the repayment menu that existed on the day you signed, none of that would have been legally possible.

What the MPN actually locks in is narrower, and it’s still meaningful.

Locked in: the principal you borrowed, your fixed interest rate, the fact that this is a federal loan governed by federal law, and the due process protections attached to federal debt — notice requirements, the right to dispute the debt, and the statutory paths out of default like loan rehabilitation.

Not locked in: the specific menu of repayment plans, the terms of any individual plan, forgiveness timelines that come from regulation rather than statute, and the identity of whoever services or collects your loan. Servicer changes alone have shuffled tens of millions of accounts over the past five years without altering a single balance.

Here’s where borrowers stand in 2026:

• Loans first disbursed on or after July 1, 2026: two options — the tiered Standard plan (10 to 25 years depending on balance) or the new Repayment Assistance Plan (RAP).
• Loans disbursed before July 1, 2026: you keep access to Income-Based Repayment (IBR) and can also elect RAP. If you’re weighing them, our RAP vs. IBR comparison runs the math both ways. Borrowers still in SAVE, PAYE, or ICR have to move to IBR or RAP, with those plans sunsetting by July 1, 2028.
• Parent PLUS borrowers: still the most restricted group, since Parent PLUS is excluded from RAP.

If you’re not sure where you land, start with our guide on how to pick a new repayment plan, and run the numbers with the RAP calculator before you commit. If you’re chasing PSLF, confirm your plan choice still generates qualifying payments.

How The Department Of Education Can Legally Change Your Repayment Options

If you signed an MPN in 2015 expecting REPAYE to exist forever, you might reasonably ask how the government was allowed to take it away. The answer is written into the MPN itself, in Item 1 of the Borrower’s Rights and Responsibilities Statement, the section you can pull up right now by logging into your StudentAid.gov account.

Here’s the operative language, straight from the Direct PLUS BRR:

The terms and conditions of loans made under this MPN are determined by the Higher Education Act of 1965, as amended (the HEA), and other federal laws and regulations.

And a few lines later:

NOTE: Amendments to the Act may change the terms of this MPN. Any amendment to the Act that changes the terms of this MPN will be applied to your loans in accordance with the effective date of the amendment. Depending on the effective date of the amendment, amendments to the Act may modify or remove a benefit that existed at the time that you signed this MPN.

That’s about as clear as legal drafting gets. The MPN incorporates federal law by reference rather than freezing it in place. When Congress changes the Higher Education Act, the terms of your note change with it — and the note warns you in advance that a benefit you had when you signed can be modified or removed. It’s the same reason forgiveness programs have appeared and disappeared over the years without anyone’s promissory note being reissued.

Four mechanisms actually move the terms, and they carry very different levels of durability.

1. Congress amends the Higher Education Act

This is the big one, and it’s what happened in 2025. The One Big Beautiful Bill Act (Public Law 119-21), signed July 4, 2025, rewrote the repayment section of the Direct Loan statute at 20 U.S.C. § 1087e. It created RAP, restricted new borrowers to two plans, eliminated Grad PLUS for new borrowers, and reset loan limits.

Statutory changes are the hardest to undo and the hardest to challenge, because Congress unquestionably has the power to amend the HEA. A borrower arguing that a 2015 MPN blocks a 2025 statute runs directly into the paragraph quoted above, which is why you’ll notice that even organized opposition in Congress fights these changes politically rather than contractually.

2. The Education Department writes regulations

Congress writes the statute, then ED writes the rules that operationalize it. For most Title IV student aid rules, ED must first run a negotiated rulemaking process (HEA § 492, 20 U.S.C. § 1098a) — a public committee of stakeholders that attempts consensus before a proposed rule goes out for comment. It’s the same machinery that has produced every major change to how student loans work for the past three decades.

That’s exactly what produced the current rules. ED convened the RISE Committee (Reimagining and Improving Student Education) in late 2025, published a proposed rule on January 30, 2026, and issued the RISE final rule on May 1, 2026, effective July 1, 2026. It set the mechanics of RAP, amended the IBR regulations, sunset ICR and PAYE by July 1, 2028, implemented the new loan limits, and confirmed RAP payments count toward PSLF.

Regulations are more fragile than statutes. A future administration can rewrite them through the same process, and they can be challenged under the Administrative Procedure Act, which is precisely what’s happening now.

3. Courts strike things down

This cuts both directions, and borrowers learned it the hard way with SAVE. In February 2025, the Eighth Circuit expanded an injunction against the plan, concluding that the Secretary’s income-contingent repayment authority didn’t stretch far enough to support SAVE’s structure, reasoning that also called the forgiveness provisions of PAYE and REPAYE into question. SAVE ultimately ended by court order rather than by a vote, leaving roughly seven million borrowers to scramble for a new plan.

Litigation is still shaping the current rules. Multiple lawsuits, including one brought by a coalition of 25 states and the District of Columbia, are challenging pieces of the RISE final rule, primarily ED’s narrow definition of which “professional degree” programs qualify for the higher $50,000 borrowing limit, a fight that will determine how much medical and nursing students can actually borrow.

4. What ED can’t do unilaterally

The MPN isn’t a blank check for the government either. A few limits are worth stating precisely, because they’re the ones you can actually enforce through the ombudsman or a formal complaint:

• ED can’t rewrite your note by fiat. The MPN says no term “may be modified or waived, unless we do so in writing.” Changes have to come through statute or properly issued regulation, not a servicer phone call or a website update. If your servicer applies terms that don’t match, that’s an error, not a rule change.
• ED can’t change your interest rate on already-disbursed loans. Your rate was fixed by statute at disbursement, which you can verify against the historical rate tables.
• ED can’t invent an obligation that isn’t in the Act. Its authority is delegated authority, which is why SAVE lost in court.
• ED can’t skip due process. Notice requirements, dispute rights, and the statutory paths out of default survive any reorganization.

The practical takeaway: don’t build a 20-year financial plan around a repayment benefit that lives in a regulation. Benefits written into law (like IBR and RAP) are meaningfully more durable than benefits created by a Secretary’s rulemaking, and that single distinction is the most useful thing to understand about federal student loan policy right now.

“If My Loans Move To Treasury, My MPN Is Invalid Because It’s With The Department Of Education”

This claim has been everywhere since March 2026, and it’s wrong. It’s also the kind of wrong that can cost someone thousands of dollars, so it’s worth walking through carefully — especially for the 7.8 million borrowers already in default who are most likely to hear it.

What people are claiming

The argument goes like this: the MPN is a contract between you and the U.S. Department of Education. If your loan moves to the Treasury Department, Treasury wasn’t a party to that contract, so the agreement is void, unenforceable, or has to be renegotiated. Some versions add that the debt becomes uncollectible entirely, which would make it the only federal debt in history to evaporate on a technicality.

What actually happened

On March 19, 2026, the Education and Treasury Departments signed an interagency agreement, the culmination of a plan first floated in 2025. It relies on 31 U.S.C. § 1535 (the Economy Act, which lets one federal agency buy services from another) and 31 U.S.C. § 3711(g), the debt collection provision of the Debt Collection Improvement Act of 1996.

Under it, Treasury’s Bureau of the Fiscal Service is taking over servicing of roughly $179 billion in defaulted federal student loans held by about 7.8 million borrowers through its Cross-Servicing program, absorbing the functions of ED’s Default Resolution Group and ramping up collections through the summer.

This is Phase 1. Phase 2 (the rest of the portfolio) and Phase 3 (FAFSA and Pell Grants) have been described by ED officials but carry no committed timeline, and Under Secretary Nicholas Kent has declined to provide one. As of mid-2026, only defaulted loans have actually moved, and even then ED retains authority over debt validity determinations, dispute adjudication, due process notices, and approval of rehabilitation and consolidation agreements. A full transfer would almost certainly require Congress, which is why House Republicans introduced ten separate bills to do it by statute.

Why the argument fails

The agreement itself says ownership doesn’t transfer. It states, in plain language, that “[r]eferrals made pursuant to this Attachment are for collection purposes only and do not transfer ownership of the debt from Education to Treasury.”

ED remains the legal holder and Treasury is acting as a collection agent. If you want to confirm this for your own loans, here’s how to find out who actually owns them.

Your MPN already contemplates this. Item 1 of the BRR defines its terms: “the words ‘we,’ ‘us,’ and ‘our’ refer to the U.S. Department of Education or our servicers.” And servicers change constantly — FedLoan wound down and its accounts were split among other companies, Navient’s federal portfolio went to Aidvantage, and Great Lakes accounts moved to Nelnet. Not one borrower’s balance disappeared, and nobody successfully argued their note was void.

Treasury has been collecting on defaulted student loans for decades. This isn’t new. The Treasury Offset Program is why defaulted borrowers have been losing their tax refunds since long before 2026, and there’s a long-established process for stopping those offsets. Cross-servicing authority under the Debt Collection Improvement Act dates to 1996. What changed in 2026 is scale and timing, not legal structure.

Your obligation runs to the United States, not to a specific agency. Direct Loans are funded by Treasury borrowing and are obligations to the federal government. The Department of Education simply administers the program on behalf of the United States and it isn’t a separate counterparty whose disappearance takes your debt with it.

Even in the scenario where Congress fully moves the program, the loans and their terms move with it — which is exactly what happened when hundreds of billions in FFEL loans were bought, sold, and assigned to ED over the years, without a single borrower’s obligation changing.

What happens if you act on the myth

If you stop paying because you believe your MPN is void, you get the ordinary consequences of default, and they arrive on a schedule you can set your watch to:

• Delinquency reported to the credit bureaus at 90 days
• Default at 270 days for most Direct Loans
• Administrative wage garnishment of up to 15% of disposable pay
• Tax refund and federal benefit offset, including a portion of Social Security
• Collection costs that can add a significant percentage to your balance
• Loss of eligibility for additional federal aid

No court has accepted the “my MPN is void because of the Treasury transfer” theory. Don’t be the test case! If you’re already behind, there are real ways to stop garnishment that don’t depend on a legal theory nobody has won with.

How To Complete A Master Promissory Note

You complete the MPN at StudentAid.gov after you’ve picked a school and been approved for federal aid, which happens after you file the FAFSA and your school builds your aid package. Your financial aid office will typically email you with instructions once your aid is approved.

You’ll need your FSA ID (the username and password for StudentAid.gov) so if you haven’t set one up, start with our walkthrough on how to create an FSA ID. You’ll also provide personal information including your Social Security number and driver’s license number.

Then you’ll list two references: people you’ve known at least three years, living in the United States at different addresses. The first is usually a parent or guardian. These are the people ED contacts if you default and can’t be reached, so pick people who will actually answer the phone in ten years.

StudentAid.gov estimates the whole process takes about 30 minutes electronically. The form takes a few minutes; the rest is reading — and reading the BRR before you sign is the single highest-return thing you can do here, because it answers most of the questions borrowers panic about five years later. It’s also worth pairing with our guide to everything you can do in your StudentAid.gov account.

What Happens After Signing The MPN?

Once you submit the MPN, ED notifies your school, and the school walks you through entrance counseling before any money is disbursed. It’s a required session explaining what it means to borrow for your education.

Use it. Ask what your total projected debt will be at graduation, what the monthly payment looks like under the Standard plan, and whether the school expects you to borrow again next year. Those three answers do more for your financial future than anything else in orientation — and they’ll tell you fast whether you’re on track with a sane order of operations for paying for college.

The MPN is a real contract, and it’s worth reading. But it’s a contract that points to federal law, which means the protections it gives you are the protections Congress wrote, and they change when Congress changes them.

This is why understanding how student loans work before you borrow beats dealing with the fallout afterward.

The practical response is to borrow less, know which of your benefits are statutory versus regulatory, and stay ahead of the plan deadlines as they land.

Master Promissory Note FAQs

Does the MPN lock in my repayment plan for the life of the loan?

No. The MPN locks in your obligation to repay under the Higher Education Act as it exists over time. Item 1 of the Borrower’s Rights and Responsibilities Statement explicitly warns that amendments to the Act “may modify or remove a benefit that existed at the time that you signed this MPN” — which is exactly what happened to SAVE, PAYE, and ICR when the 2026 rules took effect.

Do I have to sign a new MPN every year?

No. One MPN can cover up to 10 years of disbursements at the same school. You’ll sign a new one if you move from undergraduate to graduate borrowing, if you switch to a school that requires it, or if you’re a parent borrowing for a different child.

Does moving my loans to Treasury make my MPN invalid?

No. The March 2026 interagency agreement explicitly states that referrals are for collection purposes only and do not transfer ownership of the debt. ED remains the legal holder, and your obligation runs to the federal government regardless of which agency or contractor handles the account.

Which loans have actually moved to Treasury so far?

As of mid-2026, only defaulted loans — roughly $179 billion across about 7.8 million borrowers, with collections ramping up over the summer. Non-defaulted loans are part of a later phase with no committed timeline.

Can the government change my interest rate?

Your rate was fixed by statute at disbursement and doesn’t float. Rate changes in the law apply to newly disbursed loans, not retroactively — you can check what applied to each of your loans against the historical federal rate tables.

If SAVE was struck down, could IBR go away too?

They’re not in the same legal position. SAVE was created through the Secretary’s regulatory authority, which is why a court could find it exceeded that authority. IBR is written into statute at 20 U.S.C. § 1098e, so only Congress can eliminate it, and OBBBA preserved it for existing borrowers — a distinction our RAP vs. IBR breakdown walks through in more detail.

I signed my MPN in 2019. Am I stuck with the 2026 rules?

Partly. You keep IBR access and your original loan terms, and you can elect RAP. But if you’re currently in SAVE, PAYE, or ICR, you have to move to IBR or RAP by July 1, 2028 — here’s how to decide between them.

Can I get a copy of my MPN?

Yes. Log into StudentAid.gov and you can view and download every MPN you’ve signed, including the full BRR. You can also request a copy from your servicer at any time, and if you’re not sure who that is, start by finding out who owns your loans.

What happens if I don’t sign the MPN?

No MPN, no federal loan — schools can’t disburse federal loan funds without a signed note on file. If you’re up against a tuition deadline, that usually means falling back on other ways to cover the gap.

Does the MPN cover private student loans?

No. Private lenders use their own promissory notes with their own terms, and those aren’t governed by the Higher Education Act. Private loan terms genuinely are contractual in the way people mistakenly assume federal loans are — which is also why they carry far fewer built-in protections.

Is an endorser the same as a cosigner?

Functionally similar, but the MPN treats them differently. An endorser on a Direct PLUS loan agrees to repay if the borrower doesn’t, and the BRR is explicit that an endorser “is not entitled to all of the same benefits as a Direct PLUS Loan borrower.” Endorsers generally don’t get the borrower’s repayment plan options, which is one more reason to compare Parent PLUS against other financing before signing.

Can Grad PLUS borrowers still sign a new MPN?

Only if they’re grandfathered. Grad PLUS closed to new borrowers on July 1, 2026. Students already borrowing Grad PLUS before that date can generally continue for up to three more years or until they finish, whichever is shorter, as long as they stay in the same program at the same school.

Where do I go if I think my servicer is applying the wrong terms?

Start with your servicer in writing, then escalate to the FSA Ombudsman. ED retained authority over debt validity determinations and dispute adjudication even for loans referred to Treasury, so disputes still route back through the Education Department.
