Student Loan Repayment: Forgiveness vs Paying It Off

Aaron Snyder, MD

Six figures of medical school debt eventually forces a decision. Attack the balance aggressively and pay it off as fast as possible, or make the smallest payment the law requires and let the government forgive whatever remains. Getting this wrong costs real money, sometimes hundreds of thousands of dollars over a career, so it deserves more than vibes.

Four questions determine which path fits. Where do you work? How much do you owe? What do you earn? And once the bills are paid, what actually lands in your account each month? The first question determines whether forgiveness is possible in the first place. The other three determine whether forgiveness is actually the better deal.

Refinancing a federal loan permanently forfeits eligibility for Public Service Loan Forgiveness, or PSLF. The moment it is paid off through a private refinance it ceases being a federal loan and a private loan can never qualify. Physicians see a smaller monthly number with refinancing and often fail to check whether they already have qualifying payments banked.

Qualifying payments do not have to be consecutive, so a stretch at a non-qualifying employer, or a few years back in training, does not erase payments already made. It only delays how soon you reach 120. Refinancing is the one move that erases progress for good, since a nonprofit employee three years into a ten-year forgiveness path who refinances converts a loan that was heading toward tax-free forgiveness into a private loan she now owes in full.

Aggressive payoff treats the debt as a priority to eliminate. You trim discretionary spending, refinance to the lowest rate available, and put every extra dollar toward principal. This is the right approach if you work for a for-profit group, a private practice, or as an independent contractor*, since none of those employers open the door to forgiveness. It is also the right approach for anyone who simply wants the debt gone and can afford to move quickly. California and Texas have special rules regarding employment qualifications and contractor status.

The opposite approach is forgiveness. You make the smallest payment the law requires, stay on an income-driven repayment plan, and let the government cancel whatever balance remains once you have met the requirements. PSLF requires 120 qualifying monthly payments, roughly ten years, made while working full time for a nonprofit hospital, a government employer, or another qualifying public service organization. Full time, for this purpose, means at least 30 hours a week, or whatever higher threshold your own employer sets, and those hours can be combined across more than one qualifying job if neither reaches the mark on its own. Once you have made all 120 payments, the remaining balance is forgiven, and under current law that forgiveness stays permanently tax-free. That exemption is written into the PSLF statute itself, separate from the broader tax rules governing other kinds of loan forgiveness, a distinction worth understanding before you assume all forgiveness works the same way.

Consider a physician with $250,000 in federal loans at 6% interest, working at a nonprofit hospital and earning $220,000 a year. Under a standard ten-year repayment plan, she pays $2,776 a month, or $333,000 over the decade. Under an income-driven repayment plan, or IDR, pursuing PSLF, her payment is calculated as 10% of discretionary income. Discretionary income means her income is above 150% of the federal poverty line. That works out to roughly $1,638 a month, or about $196,500 over ten years, assuming her income holds steady. Whatever balance remains after the 120th payment disappears tax-free, because she qualified under PSLF specifically.

The gap between those two numbers is $136,500, and that figure does not even include the forgiven balance itself, which could add tens or hundreds of thousands more depending on how her balance moves under IDR payments over a decade. For a nonprofit physician carrying a large balance relative to income, this is rarely a close call.

Flip the scenario and the math flips with it. A physician working for a for-profit staffing group has no path to PSLF at all. For her, minimizing payments accomplishes nothing except letting interest compound. She should refinance to the lowest available rate and pay the balance down as fast as she can, since every dollar of interest avoided is a guaranteed return.

The rules underneath all of this shifted substantially this year. The One Big Beautiful Bill Act, passed in 2025, reshaped federal loan repayment starting July 1, 2026. The SAVE plan, which had let millions of borrowers make no payments at all while a legal challenge worked through the courts, was struck down by a federal appeals court in March and formally ended soon after. Time spent sitting in SAVE forbearance does not count toward PSLF or IDR credit, and borrowers cannot simply resume paying under a plan that no longer exists. They have to actively enroll in Income-Based Repayment, or IBR, still available to most existing borrowers, or in the new Repayment Assistance Plan, or RAP, which launched July 1, to start earning qualifying credit again.

If you already had federal loans before July 1, 2026, and have not borrowed anything new since, you are a legacy borrower and generally keep access to IBR, which still counts toward PSLF. The moment you take out a new federal loan, that access closes and you are moved into the new system of RAP and a restructured standard plan.

The tax treatment changed too, and the two forgiveness paths are no longer taxed the same way. From 2021 through 2025, a temporary federal provision made essentially all student loan forgiveness tax-free. That provision expired at the end of 2025 and was not renewed. Starting in 2026, forgiveness earned at the end of an income-driven repayment plan without PSLF involved, meaning the 20- or 25-year mark under Income-Based Repayment or the 30-year mark under the Repayment Assistance Plan, is once again taxable income in the year it is forgiven. A borrower with a $57,000 balance forgiven this way could owe more than $12,000 in federal tax that year. PSLF is the exception. It carries its own permanent statutory exemption that this legislation did not touch, so a balance forgiven through PSLF specifically remains tax-free, even though the underlying payments were made on the same Income-Based Repayment plan. The program itself was not eliminated, though the administration has tightened review of which employers qualify, so anyone pursuing PSLF should confirm their employer certification is current rather than assume nothing has changed.

What should I do? Start with your employer. If you work for a 501(c)(3) nonprofit, a government agency, or another qualifying public service organization, PSLF deserves serious consideration. If you are still in residency or fellowship at a qualifying institution, start making payments now instead of waiting for an attending salary. Payments made during training count toward the 120-payment total, and your required payment sits at the lowest point of your career while you are still a trainee. Every payment made as a resident is one you will not have to make later, once your income and monthly obligation are both far higher. If you work for a nonqualifying employer, a private group, a for-profit system, or as a 1099 contractor, forgiveness is off the table and aggressive payoff becomes the default, though it may still be worth weighing whether a future move toward a qualifying employer makes sense given the size of your debt.

Next, weigh your debt against your income. A large balance relative to income favors forgiveness, since the income-driven payment stays low while the eventual forgiven balance grows larger. A smaller balance relative to income often favors aggressive payoff, since you could reasonably clear it in five or six years regardless.

Finally, be honest about where your career is headed. PSLF rewards a decade of continuous qualifying employment, and if you already made payments during residency or fellowship, that window has already started shrinking in your favor. But if you might leave nonprofit medicine for private practice or industry, every year spent chasing forgiveness is a year you could have spent paying the balance down instead, and switching strategies midstream rarely works out. The honest answer depends on your specific balance, income, prior qualifying payments, and cost of living. Run your own numbers before committing to either path. A loan servicer's calculator or a carefully prompted AI model can lay out both scenarios once you feed it your real balance, payment history, income, and location. That comparison is worth doing before a flashy refinance offer makes the decision for you.

Confirm your employer qualifies, verify your payment count with your loan servicer, and run both scenarios with your actual numbers before you sign anything. A few minutes of verification now can protect years of progress toward a tax-free balance later.

Next month, we will look closely at the two repayment plans actually available to most borrowers today, Income-Based Repayment and the Repayment Assistance Plan: how each payment formula works, who benefits from which one, and how to decide between them if you have a real choice to make.
