7 student-loan mistakes doctors make in residency

Updated 2026 · Each of these is common, expensive, and almost entirely avoidable.

The short version

  • The worst mistake is forbearance — it wastes the years your payments would be smallest.
  • Most PSLF denials come down to missing paperwork, not ineligibility.
  • Residency is the time to make tiny income-driven payments that count toward forgiveness.
  • Get the foundation right now and you're ahead of most of your colleagues.

Residency is exactly when student-loan decisions matter most — and exactly when you have the least time to think about them. The good news: a handful of avoidable mistakes account for most of the damage. Here they are, worst first.

Mistake 1: Choosing forbearance during residency

Forbearance lets you skip payments — and it's almost always the wrong move for a resident. While your loans sit in forbearance, interest still piles up and none of those months count toward PSLF. On a typical six-figure balance, that's real money: a large balance can accrue roughly a thousand dollars of interest a month during training. Worse, you're throwing away the period when your income-driven payments would be smallest — the most valuable qualifying payments you'll ever make. If cash flow is tight, an income-driven plan (with a payment based on your resident salary) is almost always better than forbearance.

Mistake 2: Not enrolling in an income-driven plan early

Income-driven repayment sets your payment based on your (low) resident income — often a very small amount. Those small payments still count toward your 120 for PSLF. Staying on a standard plan, or not enrolling at all, means either higher payments than you need or no qualifying progress. Enroll early; recertify every year.

Mistake 3: Skipping the annual PSLF certification

This is the big one, and the data is stark. According to U.S. Department of Education figures, the leading reasons borrowers were denied PSLF were:

Leading reasons PSLF applications were denied Not enough qualifying payments ~56% Incomplete or missing application ~25% No eligible (Direct) loans ~14%
Source: U.S. Department of Education PSLF data. Nearly all of these denials are avoidable with two habits: consolidate to Direct Loans early, and submit your PSLF Employment Certification Form every year so your payment count stays accurate.

The pattern is clear: most denials aren't because PSLF "doesn't work" — they're because borrowers didn't certify along the way and arrived at year 10 with a count that didn't match their expectations. File the certification form every year.

Mistake 4: Not consolidating loans that need it

Only federal Direct Loans qualify for PSLF. If you have older FFEL or Perkins loans, they must be consolidated into a Direct Consolidation Loan to count — and consolidation timing has deadlines under the 2026 rules. Do this early in training so your qualifying-payment clock starts as soon as possible. Check current deadlines at studentaid.gov.

Mistake 5: Filing taxes jointly without checking "separately" first

Income-driven payments are based on your income — and how you file taxes changes what counts. For a resident married to a higher earner, filing separately can dramatically lower your monthly payment, which means more is ultimately forgiven under PSLF. It's not always the right call (it can raise your tax bill and affect other benefits), so it's worth modeling both ways. See the married-filing-separately move.

Mistake 6: Refinancing federal loans during residency

Refinancing in training is tempting — but it converts your federal loans to private debt and permanently forfeits PSLF, plus the income-driven safety net you rely on when your income is low. Your best refinance rates arrive once you're a high-earning attending anyway. If you have private loans, refinancing those early can make sense; federal loans usually should wait. See refinancing pros and cons.

Mistake 7: Not having a plan at all

The most expensive mistake is drift — making whatever payment shows up, never certifying, never modeling the alternatives. A few minutes now, with a clear plan, puts you ahead of most of your colleagues for the next decade.

Build your plan in a few minutes. AttendingFi models PSLF, the RAP plan, capped IBR, and refinancing on your real resident numbers — and tells you exactly which to choose and what to do next, free.
