Locum Tenens and Student Loans: Tax and Repayment Guide for Physicians

A hospitalist finishing residency with $280,000 in federal loans has two job offers on the table. The first is a W-2 employed position at a nonprofit hospital — PSLF-eligible, predictable income, $230,000/year. The second is a locum tenens contract through a staffing agency — 1099 income, $340,000/year, no employer, no PSLF eligibility.

That $110,000 income gap looks obvious. The loan math is not.

Locum tenens work has exploded post-pandemic. The American Staffing Association estimates the locum tenens market exceeded $5 billion in 2023, with demand driven by physician shortages across rural hospitals, VA facilities, and understaffed emergency departments. Tens of thousands of physicians work locum contracts either full-time or alongside a permanent position. Most of them are carrying six-figure medical school debt and have no idea how the 1099 structure changes their repayment strategy — or their tax bill.

This guide breaks down exactly what locum tenens physicians need to know about student loans, self-employment taxes, income-driven repayment, and whether refinancing makes sense when your income is variable.

How Locum Tenens Income Affects Student Loan Repayment

The single biggest repayment issue for locum physicians isn't the income — it's how that income gets classified.

When you work as a 1099 independent contractor through a locum staffing agency, your adjusted gross income (AGI) is determined by your net self-employment earnings after business deductions. This matters enormously for income-driven repayment, because IDR payments are calculated on AGI, not gross income.

Here's what that looks like in practice:

A locum emergency physician earns $380,000 gross in 2025. After deducting malpractice tail coverage ($12,000), health insurance premiums ($8,400), a SEP-IRA contribution ($66,000 — the 2024 maximum), home office and licensing fees ($4,000), and travel expenses for assignments ($9,000), their AGI drops to roughly $280,600. The self-employment tax deduction (half of self-employment tax) reduces it further.

That AGI matters because under IBR (Income-Based Repayment), which is currently the default income-driven plan for most borrowers as of 2026, your monthly payment is calculated as 10% of discretionary income for new borrowers. Discretionary income is AGI minus 225% of the federal poverty line. For a single borrower in the continental U.S. in 2025, that's roughly $33,300.

At a $280,600 AGI: ($280,600 − $33,300) × 10% / 12 = approximately $2,061/month.

Compare that to the same physician earning $280,000 as a W-2 employee with no deductions: payment would be roughly the same. But the locum physician's gross income was $100,000 higher — the deductions did real work.

This is why locum physicians who are pursuing loan forgiveness or riding out IDR need to be strategic about maximizing legitimate deductions before recertifying their income.

PSLF Is Off the Table for Full-Time Locum Work

This needs to be said directly: locum tenens physicians working through staffing agencies do not qualify for Public Service Loan Forgiveness.

PSLF requires that you be employed by a qualifying employer — a 501(c)(3) nonprofit, government entity, or certain public hospitals. The staffing agency itself is the employer of record for most locum arrangements, and staffing agencies are for-profit entities. Even if you're physically working at a nonprofit hospital, your PSLF employer certification will be denied because you're employed by the agency, not the hospital.

There is one exception worth noting: some physicians negotiate direct employment contracts with a qualifying hospital rather than going through a staffing intermediary. In those cases, PSLF eligibility may survive — but this requires careful contract review and PSLF employer certification before assuming you qualify. Studentaid.gov offers the PSLF Employer Search tool to check specific entities.

If you're a locum physician who was previously making PSLF-qualifying payments and is now considering locum work, understand that your PSLF qualifying payment count stops the moment you leave qualifying employment. Months spent as a 1099 contractor do not count toward the 120 required payments — period.

For physicians who were banking on PSLF, this can change the entire calculus. A family medicine physician with $200,000 in loans who was 3 years into PSLF qualifying payments should think hard before switching to full-time locum tenens, even if the income jump is substantial.

The Self-Employment Tax Problem (and How to Offset It)

Here's the tax hit that blindsides locum physicians who come from W-2 employment: self-employment tax.

As a W-2 employee, you pay 7.65% in FICA taxes (Social Security + Medicare) and your employer pays the other 7.65%. As a 1099 contractor, you pay both sides — 15.3% on the first $168,600 of net earnings (2024 threshold) and 2.9% Medicare tax above that, plus an additional 0.9% Additional Medicare Tax above $200,000.

For a locum physician netting $300,000 in self-employment income, the self-employment tax burden can exceed $25,000 — money that simply doesn't exist in a comparable W-2 position.

The offset tools available to 1099 physicians include:

SEP-IRA contributions: In 2024, you can contribute up to 25% of net self-employment income or $66,000, whichever is less. At a $300,000 net income, that's a $66,000 pre-tax deduction — reducing both income tax and AGI (which, as shown above, directly reduces IDR payments).

Solo 401(k): Potentially more powerful than a SEP-IRA for physician incomes. You can contribute as both employee ($23,000 in 2024, plus $7,500 catch-up if over 50) and employer (25% of compensation). The total can also reach $66,000/$73,500 but offers more flexibility in structuring.

Health insurance deductions: Self-employed physicians can deduct 100% of health, dental, and vision insurance premiums for themselves and their family — above the line, reducing AGI directly.

Malpractice and tail coverage: Fully deductible as a business expense.

Professional expenses: Licensing fees, DEA registration, board certification costs, medical journals, CME, and work-related travel are all deductible when properly documented.

Physicians doing locum work across multiple states may also owe state income taxes in each state where they work. A physician completing assignments in Texas (no income tax), California (13.3% top rate), and New York (10.9% top rate) in the same year will need to file multiple state returns and potentially pay substantial state taxes — which are deductible on the federal return but add significant complexity.

IBR Recertification with Variable Locum Income

One of the practical headaches of locum work is income variability. You might earn $420,000 one year and $210,000 the next if assignments dry up or you take time off. This creates a recurring question: when and how do you recertify your income for IDR?

The answer is timing. You can recertify your income at any time — you don't have to wait for your annual recertification date. If your income dropped significantly (say, after a slow quarter or a gap between contracts), you can submit updated income documentation and get your payment recalculated immediately.

For locum physicians who are riding IDR toward the 20-25 year forgiveness window rather than pursuing PSLF, this flexibility is valuable. A high-income year followed by strategic deductions can be recertified down; a low-income year between contracts can trigger a lower payment.

A word on SAVE: as of March 10, 2026, the SAVE plan was vacated by the 8th Circuit Court of Appeals. Borrowers previously enrolled in SAVE have been transitioned to other IDR plans or placed in administrative forbearance during litigation. As of 2026, IBR is effectively the standard IDR path for most borrowers. The new RAP (Repayment Assistance Plan) applies only to loans disbursed on or after July 1, 2026, and is not available to physicians with existing medical school debt.

Should Locum Tenens Physicians Refinance?

With no PSLF eligibility and higher incomes, many locum physicians are strong refinancing candidates — but the variable income question complicates the calculus.

Refinancing converts federal loans to private loans, which means you permanently lose access to IBR, IDR forgiveness, deferment, and any future federal programs. For a locum physician who might have inconsistent income year to year, that loss of payment flexibility is a real risk.

The physicians for whom refinancing makes the most sense in a locum context:

• High earners with manageable debt: A locum orthopedic surgeon earning $500,000+ with $180,000 in loans has no realistic shot at IDR forgiveness — the payments under IBR would pay off the balance before the 20-year forgiveness window. Refinancing to a 5-year fixed rate saves significant interest.
• Physicians with stable locum income: Emergency medicine physicians working steady contracts through the same agency year-round have predictable income more similar to traditional employment.
• Those with no PSLF history: If you never pursued PSLF and don't plan to return to qualifying employment, keeping federal loans for protections you'll never use doesn't make sense.

Quarterly Estimated Taxes: Don't Skip This Step

Every locum physician working as a 1099 contractor must pay quarterly estimated taxes to the IRS — due April 15, June 15, September 15, and January 15. Failing to do so results in underpayment penalties on top of your regular tax bill.

A simple rule: set aside 30–35% of every locum check into a separate savings account the day it lands. Don't touch it. Pay estimated taxes quarterly from that account. This single habit prevents the most common financial disaster in locum medicine — a $60,000–$80,000 tax bill in April with no cash to pay it.

For income-driven repayment purposes, locum income is self-employment income that counts as AGI. Your IDR payment will be recertified annually based on your tax return, so a high-earning locum year will trigger higher IDR payments the following year. Plan accordingly.

Frequently Asked Questions

Can locum tenens physicians qualify for PSLF? Generally no. Most locum arrangements are through staffing agencies, which are for-profit entities that don't qualify as PSLF employers. Even if you're placed at a qualifying hospital, employment is typically through the agency — not the hospital. There are narrow exceptions (some direct-hire locum arrangements with qualifying employers), but assume PSLF is off the table unless you verify your specific employment structure via the PSLF Help Tool at studentaid.gov.

Should I stay on IBR or refinance as a locum physician? It depends on your income stability and debt level. If you earn $300,000+ consistently and owe under $250,000, refinancing to a 5-year private loan often saves more interest than keeping federal protections you won't use. If your income varies significantly year to year, IBR's income-based payments provide a safety net that refinancing eliminates permanently.

Does locum income count for IDR recertification? Yes. Your IDR payment is based on your adjusted gross income from your most recent tax return. A high-earning locum year — say $350,000 — will trigger a higher IBR payment the following year. Under IBR, that payment would be approximately $3,000–$3,200/month, which approaches aggressive payoff territory. Plan your repayment strategy around your expected income range, not just your highest-earning year.

What happens to my SAVE enrollment as a locum physician? SAVE was vacated by the 8th Circuit in March 2026. Borrowers in SAVE are now in administrative forbearance — months there don't count toward IDR forgiveness or PSLF. Switch to IBR as soon as possible via studentaid.gov if you haven't already.

Is disability insurance more important for locum physicians? Yes. Locum physicians often have no employer-sponsored disability coverage, no paid sick leave, and no income if they can't work. If your loans are refinanced into private debt, inability to work means both loan payments and living expenses pile up with no income and no IDR payment flexibility. Own-occupation disability insurance is non-negotiable before refinancing as a locum physician.
