The PSLF Buyback Program in 2026: How It Works, What It Costs, and How to Apply

If you are years into Public Service Loan Forgiveness and just learned that some of your forbearance or deferment months do not count toward your 120 payments, you are not alone, and you are not out of options. A program called PSLF Buyback lets you retroactively pay for those missing months and count them toward forgiveness. It is not automatic, and it is not always cheap, but for many borrowers it is the fastest legitimate path to the finish line.

This guide explains who qualifies, how the Department of Education calculates what you owe, the steps to apply, and the deadlines that can void your buyback agreement if you miss them.

What Is PSLF Buyback?

PSLF Buyback lets a borrower make a lump-sum payment equal to what their income-driven repayment (IDR) payment would have been during a period of deferment or forbearance that did not otherwise count toward the 120 qualifying payments PSLF requires. Once you pay, those months are added to your payment count as if you had made regular payments during them.

It exists because certain administrative pauses, most notably the SAVE plan forbearance that began in 2024, stopped borrowers' payment counters even though many of those borrowers were still working full-time for a qualifying employer. Buyback is the Department's mechanism for making those borrowers whole without requiring them to have paid twice.

Who Qualifies for PSLF Buyback

You are generally eligible if all of the following are true:

• You have a Direct Loan with an outstanding balance. If you have FFEL or Perkins loans, you must consolidate into a Direct Consolidation Loan first, and you cannot buy back months that occurred before that consolidation loan's first disbursement date.
• You certified qualifying public service employment for the months you want to buy back, meaning you actually worked for a qualifying nonprofit or government employer during that time.
• Buying back those months would bring your total to at least 120 qualifying payments. If you are still years away from 120 even after a successful buyback, the program will not help you yet, and you should keep making regular payments in the meantime.

Months That Can Be Bought Back

If you had qualifying employment during these periods, they are generally eligible:

• The COVID-19 payment pause, March 2020 through September 2023
• SAVE plan administrative forbearance
• Financial hardship deferment
• Medical or dental internship or residency deferment
• Active military duty deferment
• Certain emergency-declaration forbearances

Months That Never Qualify

Some periods are permanently excluded from buyback, no matter your employment status:

• In-school deferment, even if you were working full-time
• Standard post-graduation grace periods
• Time in default or bankruptcy
• Periods under total and permanent disability monitoring

How Much Will Buyback Cost You?

The cost depends on your repayment situation during the months you are buying back, and it is worth understanding both paths before you apply.

If you were enrolled in an income-driven repayment plan immediately before or after the gap, the Department uses whichever of those two monthly payments was lower and multiplies it by the number of months you are buying back. For a borrower whose IDR payment was $50 a month, six months of buyback would cost $300 total.

If you were not enrolled in an IDR plan, or the gap lasted 12 months or longer, the Department asks for your tax returns and family size documentation from that period. It uses that information to calculate what your IDR payment would have been. If you do not respond within 30 days, the calculation defaults to the 10-year Standard Repayment Plan amount, which is typically far more expensive, so this deadline matters.

There is one genuinely good provision built into the formula: if your calculated IDR payment for a given month would have been $0 because your income fell below the poverty guideline for your family size, that month costs nothing to buy back. And no monthly buyback amount can exceed what you would have paid under the 10-year Standard Plan.

The March 2026 Calculation Change

If your gap in payments happened while you were on the SAVE plan, pay close attention to this change. As of March 31, 2026, the Department stopped using the SAVE plan's own formula, which had higher income exemptions and produced lower payment estimates, to calculate buyback costs. Instead, it now uses the IDR plan you were enrolled in immediately before SAVE, such as IBR, PAYE, or ICR, or it requests updated income documentation to find the lowest payment you would have qualified for under an available plan.

For some borrowers this change roughly triples the cost of buying back the same months, since older repayment formulas generally required a larger share of income than SAVE did. If you were counting on SAVE-era math to keep your buyback bill small, it is worth requesting your buyback estimate now so you know the real number before committing.

Why the On-Time Payment Rule Makes Buyback More Important

Buyback matters more than it used to because of a separate change that took effect July 1, 2026: PSLF no longer allows a grace period on payment due dates. Before that date, a payment arriving up to 15 days late still counted toward your 120. Now, a qualifying payment must arrive on or before its due date, under every repayment plan, with no exceptions. The change is not retroactive, so late payments made before July 1, 2026 still count, but anything after that date must be exactly on time.

That combination, a stricter rule going forward and a formal repair mechanism for the past, is why understanding buyback now is worth the effort. It is realistically the only tool available to recover months lost to forbearance gaps, since there is no equivalent grace period for missed due dates anymore.

How to Apply, Step by Step

1. Certify your qualifying employment. Use the PSLF Help Tool on StudentAid.gov to make sure every employer during the months you want to buy back is properly certified.
2. Identify the months you want to buy back. Compare your PSLF payment tracker against your actual employment history to find deferment or forbearance months where you were working for a qualifying employer.
3. Submit a PSLF Reconsideration request. Select "PSLF Buyback" as your reason, and include language along these lines: "I have at least 120 months of approved qualifying employment, and I am seeking PSLF discharge through PSLF Buyback."
4. Respond to documentation requests within 30 days. If the Department asks for tax returns or family size information, missing this window triggers the more expensive default calculation.
5. Review your buyback agreement carefully. It arrives by email, so check your spam folder. The agreement will state the exact amount owed and the payment deadline.
6. Pay the full lump sum within 90 days. The clock starts when the agreement is sent, not when you open it.
7. Wait for processing. Forgiveness typically takes another 60 to 90 days after payment is received and confirmed.

Deadlines You Cannot Miss

• 30 days to submit tax returns and family size documentation once requested, or you risk the more expensive default calculation.
• 90 days from the date your buyback agreement is sent to pay the full amount, or the agreement is voided. Any partial payment already made is credited as a regular loan payment instead, not refunded.
• There is currently a significant backlog of pending buyback requests, so expect the review itself, before you even receive an agreement, to take months. The Department does not provide status updates while a request is pending.

What to Do If You're Not Sure Buyback Is Worth It

Buyback only makes sense if paying now gets you to 120 qualifying payments, or close enough that the remaining months are manageable. Before you apply, ask yourself two questions. First, how many qualifying payments do you actually have certified right now, including any months you might buy back? Second, is the estimated cost meaningfully less than what you would otherwise pay over the same stretch of regular monthly payments?

If buying back a handful of months gets you to 120 and off your loans entirely, the math usually favors buyback even at a few hundred dollars a month, since the alternative is continuing to pay for years. If you are still 40 or 50 payments away from 120, it is usually better to keep making regular qualifying payments and revisit buyback once you are closer to the finish line.

A Realistic Example

Consider a public school teacher with 114 certified qualifying payments who took six months of SAVE plan forbearance in 2024 while still working full-time at her school. Her IDR payment immediately before that forbearance was $50 a month. Under the standard calculation, six months of buyback would cost her $300 total, roughly $50 per remaining month, and would immediately push her past the 120-payment threshold into forgiveness. For a borrower this close to the end, buyback can be the difference between years of additional payments and a one-time bill measured in the low hundreds of dollars.

Not every borrower's numbers will look this favorable, especially after the March 2026 formula change, which is exactly why requesting your personalized buyback estimate before committing is worth the wait.

Frequently Asked Questions

Does PSLF Buyback cost the same for everyone? No. Your cost depends on your income, family size, and repayment plan during the specific months you are buying back. Two borrowers who took the same forbearance can owe very different amounts.

Can I buy back grace period months? No. Standard post-graduation grace periods are permanently excluded from buyback, regardless of your employment status during that time.

What happens if I miss the 90-day payment deadline? Your buyback agreement is voided. If you made a partial payment, it is applied as a regular loan payment rather than refunded, and you would need to start the reconsideration process over.

Will buying back months guarantee I reach forgiveness? Only if the months you buy back, combined with your existing certified payments, bring your total to 120 or more. Confirm your current count before applying so you know whether buyback actually closes the gap.

Is PSLF forgiveness still tax-free after these changes? Yes. PSLF forgiveness remains permanently tax-free at the federal level. None of the 2026 calculation or grace-period changes affect that.

The Bottom Line

PSLF Buyback is not a shortcut, and after the March 2026 formula change it is not always cheap, but it remains the clearest path for borrowers who lost qualifying months to forbearance gaps they did not choose. If you think you might be close to 120 payments, start by certifying your employment history and requesting a buyback estimate so you are working from real numbers instead of guesses. And going forward, since the 15-day grace period no longer exists, consider setting up autopay a few days before your due date so you never have to think about buyback again.
