Tax Deductions for Medical Residents: Credits, Loans, and Moonlighting

Tax deductions for medical residents cluster in a few predictable places: the student loan interest you paid during the year (up to $2,500), contributions to a Health Savings Account if your hospital plan qualifies, and in many cases a Traditional IRA contribution. Credits like the Lifetime Learning Credit, the Child Tax Credit, and the Saver’s Credit can shave more off the bill than any deduction. The expenses most residents assume are deductible — scrubs, textbooks, board exams, CME, licensing fees — generally are not at the federal level, and that rule is now permanent.

The Deductions That Actually Move the Needle

Three deductions sit on Schedule 1 of Form 1040 and lower your adjusted gross income whether or not you itemize. A lower AGI can also keep you eligible for credits that phase out at higher incomes, so these are worth claiming first.

Student Loan Interest

You can deduct up to $2,500 in interest paid on qualified student loans, and you don’t have to itemize to take it.¹ The loan has to have been used for qualified education expenses such as tuition, room and board, or required supplies.

For 2026, the deduction phases out for single filers with modified adjusted gross income between $85,000 and $100,000, and for married couples filing jointly between $175,000 and $205,000. Most residents in the early years of training sit well under those thresholds. A resident married to a higher-earning spouse may lose part or all of the benefit.

Health Savings Account Contributions

If your hospital’s health plan qualifies as a high-deductible health plan, every dollar you put into a Health Savings Account is deductible. For 2026, an HDHP must have a minimum annual deductible of at least $1,700 for self-only coverage or $3,400 for family coverage.²

The 2026 contribution ceiling is $4,400 for self-only coverage and $8,750 for family coverage, inclusive of anything your employer contributes.² HSA money grows tax-free and comes out tax-free for qualified medical expenses. Confirm your plan qualifies before contributing; putting money into an HSA when you aren’t covered by an HDHP triggers a 6% excise tax on the excess.

Traditional IRA Contributions

You can contribute up to $7,500 to a Traditional IRA for 2026.³ Whether it’s deductible depends on whether your hospital offers a retirement plan like a 403(b) or 401(k). With no workplace plan, the full contribution is deductible regardless of income.

If you are covered by a workplace plan, the 2026 deduction phases out between $81,000 and $91,000 of MAGI for single filers, and between $129,000 and $149,000 for married couples filing jointly.⁴ Most first- and second-year residents earning in the mid-$60,000 range qualify for the full deduction even with a workplace plan. If your deduction is phased out, a Roth IRA (not deductible now, grows tax-free) is usually the better move at resident-level income.

Standard Deduction or Itemize

The 2026 standard deduction is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household.⁴ Those numbers are high enough that most residents come out ahead taking the standard deduction and don’t need to think further about Schedule A.

Itemizing tends to pay off when you own a home with meaningful mortgage interest, or when you live in a high-tax state. The state and local tax deduction cap rose to roughly $40,000 under the One Big Beautiful Bill Act (up from $10,000), which helps high-tax-state residents considerably. Unreimbursed medical expenses are deductible only to the extent they exceed 7.5% of your AGI, so on a $65,000 resident salary the first roughly $4,875 produces no deduction at all; for most healthy residents this is a non-factor.⁵ Charitable contributions and home mortgage interest round out the itemized deductions most likely to come into play.

Scrubs, Textbooks, Board Exams, and CME

This is where residents lose the most money to misunderstanding. The Tax Cuts and Jobs Act eliminated the deduction for unreimbursed employee business expenses starting in 2018, and the One Big Beautiful Bill Act made that elimination permanent.⁶ As a W-2 employee, you cannot deduct work-related costs your hospital doesn’t reimburse, including:

Professional society dues and membership fees
Continuing medical education courses and conferences
Medical textbooks, journals, and review materials
Scrubs, lab coats, and work-specific clothing
Stethoscopes and personal medical instruments

The practical response is to push your program’s GME office for reimbursement. Many residencies have CME stipends and book allowances that go underused because residents don’t ask.

Initial medical licensure fees and board certification exams (USMLE Step 3, specialty boards) sit in the same bucket. The IRS treats them as costs that qualify you for a new profession rather than costs that maintain existing skills, which makes them non-deductible personal expenses. Even arguing that a board exam maintains existing skills still leaves the expense in the unreimbursed-employee category, which is permanently non-deductible for W-2 workers.

One exception worth knowing: several states did not adopt the federal suspension. California, New York, Pennsylvania, Minnesota, and Hawaii still allow W-2 employees to deduct work-related expenses on the state return. If you train in one of those states, keep every professional expense receipt. The federal return won’t benefit, but your state return might.

Credits That Residents Should Check

A credit reduces your tax bill dollar for dollar. A deduction only saves you the deduction multiplied by your marginal rate. That makes credits more valuable than deductions of the same size, and residents should run through each of the following every year.

Lifetime Learning Credit

The Lifetime Learning Credit covers qualified education expenses for courses that improve job skills, which can include CME courses and board review programs if they’re taken at an eligible educational institution. The credit equals 20% of the first $10,000 you spend on qualified expenses, for a maximum of $2,000 per return.⁷

The LLC is non-refundable (it can zero out your tax, but won’t generate a refund). It phases out for single filers with MAGI between $80,000 and $90,000, and for joint filers between $160,000 and $180,000.⁴ Those ranges haven’t been adjusted for inflation since 2020, so senior residents and those with a working spouse may bump up against the ceiling.

Note that the American Opportunity Tax Credit, the other major education credit, is limited to the first four years of postsecondary education. Residency falls well past that mark, so the AOTC is effectively unavailable to residents.⁸

Child Tax Credit and Credit for Other Dependents

Residents with children should claim the Child Tax Credit, worth up to $2,200 per qualifying child under age 17 for 2026. Up to $1,700 of it is refundable, so you can receive that amount even if your tax liability drops to zero. The child must have a valid Social Security number.⁹

The credit begins to phase out at $200,000 of MAGI for single filers and $400,000 for joint filers.⁹ Virtually every resident falls below those thresholds.

If you support a dependent who doesn’t qualify for the CTC (a child 17 or older, or an elderly parent living with you), you may be able to claim the Credit for Other Dependents, which provides up to $500 per qualifying dependent as a non-refundable credit, with the same phase-out thresholds.¹⁰

Saver’s Credit

The Retirement Savings Contributions Credit (the Saver’s Credit) gets missed by most residents because it sounds like a low-income benefit. The income limits actually overlap with resident salaries. For 2026, single filers with AGI up to $40,250 can claim the credit, and married couples filing jointly qualify with AGI up to $80,500.³

The credit is a percentage (50%, 20%, or 10%, depending on AGI) of the first $2,000 you contribute to an IRA, 401(k), or 403(b). A single resident earning $55,000 is above the $40,250 cap and would not qualify. A married couple where the resident earns $65,000 and the spouse earns $15,000 would come in under $80,500 and could receive a credit of $200 to $1,000 on a $2,000 contribution. The credit is non-refundable, so it’s only useful against actual tax liability.

Loan Forgiveness and What It Will Cost You

Many residents are heading toward Public Service Loan Forgiveness after 120 qualifying monthly payments at a qualifying employer, which includes most nonprofit hospital systems and academic medical centers. PSLF forgiveness is not taxable income, and that exclusion is written into the federal tax code with no expiration date.¹¹

Other forms of forgiveness are a different story. The American Rescue Plan Act temporarily excluded all forgiven student loan debt from federal taxable income through the end of 2025. That provision has now expired. Starting in 2026, borrowers who receive forgiveness under income-driven repayment plans after 20 or 25 years will owe federal income tax on the forgiven balance, and some states may tax it as well.

For residents choosing between tracks, the tax treatment matters as much as the monthly payment. A $200,000 balance forgiven under IDR could produce a tax bill of $40,000 or more, depending on your bracket at the time. PSLF produces no tax bill. That gap often makes staying on PSLF worthwhile even when it requires close attention to employer eligibility and payment certification.

If You Moonlight on a 1099

Extra shifts at urgent-care clinics, telehealth companies, or through locum agencies often come as independent contractor work (a 1099-NEC rather than a W-2). That changes your tax picture in several ways.

Self-Employment Tax

Independent contractor income carries self-employment tax of 15.3%, covering both the employer and employee portions of Social Security (12.4%) and Medicare (2.9%).¹² That is on top of regular income tax. You can deduct half of the self-employment tax as an above-the-line adjustment, which softens the hit, but the effective rate on moonlighting income is still noticeably higher than on your W-2 salary.

Deductible Business Expenses

Moonlighting on a 1099 opens doors your W-2 job keeps shut. Expenses tied to your 1099 work are deductible on Schedule C even though the same expenses tied to your residency are not. Common ones include:

Malpractice insurance premiums for the independent contractor work
Mileage between your primary workplace and a moonlighting site (72.5 cents per mile for 2026)¹³
Travel and lodging when a moonlighting assignment takes you away from your home area
Licensing fees directly attributable to the 1099 work

The expense has to tie directly to the 1099 income. You can’t deduct ordinary residency expenses just because you also have some moonlighting income.

Estimated Tax Payments

Nothing is withheld from 1099 payments. If you expect to owe $1,000 or more in additional tax from moonlighting, make quarterly estimated payments to avoid an underpayment penalty. The 2026 deadlines are April 15, June 15, September 15, and January 15 of the following year.¹⁴

A simpler alternative: ask your hospital payroll to increase federal withholding on your W-2. Extra W-2 withholding is treated as paid evenly across the year, so bumping it up in November to cover moonlighting income earned in March doesn’t trigger an underpayment penalty for the earlier quarters. Many residents find this easier than tracking quarterly vouchers.
