Tax Deductions for Medical Residents: Credits and Moonlighting

Tax deductions for medical residents come down to a short list: student loan interest, HSA contributions, sometimes a Traditional IRA contribution, and a few tax credits. Almost everything else residents assume they can write off — scrubs, stethoscopes, board exams, CME, professional dues — is no longer deductible on a federal return for W-2 employees, and under the One Big Beautiful Bill Act that change is now permanent.

Here is what actually moves the needle on a resident’s return, what doesn’t, and where moonlighting income changes the rules.

Above-the-Line Deductions You Can Claim Without Itemizing

Above-the-line deductions sit on Schedule 1 and reduce your adjusted gross income whether or not you itemize. Because a lower AGI can also keep you inside phase-outs for credits, these deductions do more work than their dollar amounts suggest.

Student Loan Interest

This is the deduction nearly every resident should be claiming. You can deduct up to $2,500 in interest paid on qualified student loans during the year, even if you take the standard deduction.¹ The loan must have been used for qualified education expenses such as tuition, room and board, or required supplies.

The deduction phases out based on modified adjusted gross income. For 2026, single filers begin losing it at $85,000 of MAGI and lose it entirely at $100,000. Married couples filing jointly phase out between $175,000 and $205,000. Most residents fall under these thresholds, but a resident married to a higher-earning spouse may lose some or all of the benefit.

HSA Contributions

If your hospital’s health plan qualifies as a high-deductible health plan, you can contribute to a Health Savings Account and deduct every dollar. 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 limits are $4,400 for self-only coverage and $8,750 for family coverage, and those limits include anything your employer contributes.² The 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 excess contributions.

Traditional IRA Contributions

You can contribute up to $7,500 to a Traditional IRA for 2026.³ Whether the contribution is 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’re covered by a workplace plan, the deduction phases out based on MAGI. Single filers phase out between $81,000 and $91,000 for 2026. Joint filers phase out between $129,000 and $149,000.⁴ Most first- and second-year residents earning in the mid-$60,000s qualify for the full deduction even with a workplace plan. If the deduction is phased out, a Roth IRA contribution is usually the better move at resident income.

Standard Deduction Versus Itemizing

For 2026, the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.⁴ Those numbers are high enough that the vast majority of residents come out ahead taking the standard deduction. Itemizing only helps when your eligible expenses exceed that amount.

The residents who benefit from itemizing usually own a home with meaningful mortgage interest or live in a high-tax state. The itemized deductions most likely to matter:

State and local taxes (SALT), deductible up to a combined cap of roughly $40,000 under the One Big Beautiful Bill Act — a significant increase from the prior $10,000 cap.
Home mortgage interest, if you own.
Unreimbursed medical expenses, but only to the extent they exceed 7.5% of your AGI. On a $65,000 salary, the first roughly $4,875 produces no deduction, which makes this a non-factor for most healthy residents.⁵
Cash charitable contributions to qualified organizations, subject to AGI-based limits.

Professional Expenses You Can’t Deduct Anymore

This is where residents lose the most money to bad assumptions. Scrubs, textbooks, licensing fees, board-prep courses — before 2018 these were deductible as unreimbursed employee expenses. They aren’t anymore, and that change is now permanent.

The Tax Cuts and Jobs Act of 2017 eliminated the deduction for unreimbursed employee business expenses starting in 2018. That suspension was originally set to expire after 2025, but the One Big Beautiful Bill Act made it permanent.⁶ As a W-2 employee, you cannot deduct work-related expenses your hospital doesn’t reimburse, including:

Professional society dues and membership fees
CME courses and conferences
Medical textbooks, journals, and review materials
Scrubs, lab coats, and other work-specific clothing
Stethoscopes and personal medical instruments
USMLE Step 3, specialty board exam fees, and initial licensure costs

Initial licensure and board certification are treated by the IRS as costs that qualify you for a new profession rather than costs that maintain existing skills, which puts them in the non-deductible personal expense category. Even a maintenance-of-skills argument runs into the permanent suspension for W-2 employees.

The practical move 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.

One footnote worth knowing: several states, including California, New York, Pennsylvania, Minnesota, and Hawaii, did not adopt the federal suspension. If you train in one of these, keep receipts for professional expenses. The federal return won’t benefit, but your state return might.

Tax Credits Worth Checking

Credits are more valuable dollar-for-dollar than deductions. A $2,000 credit saves you $2,000; a $2,000 deduction at the 22% bracket saves you $440.

Lifetime Learning Credit

The Lifetime Learning Credit is the education credit most likely to help during residency. It covers qualified education expenses for courses that improve job skills, which can include CME or board review programs taken at an eligible educational institution. The credit equals 20% of the first $10,000 spent, for a maximum of $2,000 per return.⁷

The LLC is non-refundable, so it can reduce your tax to zero 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 limit.

Note that the American Opportunity Tax Credit is limited to the first four years of postsecondary education, which makes it unavailable to nearly all medical 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 the credit is refundable, meaning you can receive that amount as a refund even if your tax liability drops to zero. The child must have a valid Social Security number.⁹

The credit phases out starting at $200,000 of MAGI for single filers and $400,000 for joint filers, so virtually every resident qualifies in full. If you support a dependent who doesn’t qualify for the CTC — an older child, an elderly parent — you may claim the Credit for Other Dependents, worth 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 is overlooked because it sounds like it’s only for low-income filers, but its income limits overlap with resident salaries. For 2026, single filers with AGI up to $40,250 can claim the credit; joint filers qualify up to $80,500.³

The credit is 50%, 20%, or 10% of the first $2,000 you contribute to a retirement account, depending on AGI. A single resident earning $55,000 wouldn’t qualify, but a married-filing-jointly couple with one resident earning $65,000 and a spouse earning $15,000 could receive $200 to $1,000 on a $2,000 contribution. The credit is non-refundable.

How Moonlighting Changes What You Can Deduct

If you moonlight and are paid as an independent contractor (1099-NEC), the picture changes in both directions. Independent contractor income is subject to self-employment tax of 15.3%, covering both the employer and employee portions of Social Security (12.4%) and Medicare (2.9%).¹¹ You can deduct half of that as an above-the-line adjustment, but the overall effective rate on moonlighting income is still higher than on W-2 salary.

The upside: expenses tied to your 1099 work are fully deductible on Schedule C, even though the same expense for your residency job is not. Common Schedule C deductions include:

Malpractice insurance premiums for your independent contractor work
Mileage between your primary workplace and a moonlighting site, at 72.5 cents per mile for 2026¹²
Travel and lodging when a moonlighting assignment takes you out of your home area
Licensing fees directly attributable to the independent contractor work

The expense has to be directly tied to the 1099 income. You cannot pull your regular residency expenses onto Schedule C just because you also have some moonlighting income.

Because no taxes are withheld from 1099 payments, if you expect to owe $1,000 or more in additional tax you generally need to make quarterly estimated payments to avoid an underpayment penalty.¹³ A simpler alternative is asking payroll to increase federal withholding on your W-2 salary; extra W-2 withholding is treated as paid evenly throughout the year, which avoids per-quarter penalties.

A Note on Loan Forgiveness

Many residents plan to pursue Public Service Loan Forgiveness after 120 qualifying monthly payments while working for 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.¹⁴

Forgiveness under income-driven repayment plans is different. The American Rescue Plan Act temporarily excluded all forgiven student loan debt from federal taxable income through the end of 2025, and that provision has expired. Starting in 2026, borrowers who receive forgiveness under IDR plans after 20 or 25 years of payments will owe federal income tax on the forgiven balance, and some states may treat it as taxable income too. 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 at all, which is a meaningful reason many residents stay on the PSLF track.
