Tax Deductions for Physicians: The 2026 Guide by Income Type

Here is the paradox at the center of physician finances. Doctors are among the highest earners in the country, yet most feel they keep too little of it. The Medscape 2026 Physician Compensation Report put average physician compensation at $386,000, with specialists near $417,000 and eight specialties above $500,000. In the same survey, 61% of physicians said the profession is underpaid, and a large share now pick up locum tenens shifts, moonlighting, or consulting on top of a day job.

That combination, high income plus a tangled mix of W-2, 1099, and partnership pay, is exactly what makes physician taxes different, and exactly where money gets left on the table. The deductions that matter to a doctor depend almost entirely on how you are paid, not just what you spend. A hospital-employed attending and a private-practice owner can spend the same dollars on the same things and get completely different tax results.

This guide is organized the way physicians actually experience taxes: by income type. It is current for 2026, including the changes from the One Big Beautiful Bill Act (OBBBA) signed in July 2025, and it favors the same year-round, plan-ahead approach that separates strategic tax planning from simple tax preparation. One honest disclaimer first: this is education, not advice for your specific return. Physician situations vary widely, so treat the judgment calls here as conversations to have with your CPA.

Why a physician’s tax situation is different

Three things set doctors apart at tax time.

First, income level. Most attendings sit in the top federal bracket, which magnifies the value of every legitimate deduction and every dollar of tax-deferred saving.

Second, income mix. By a few years into practice, many physicians hold some blend of W-2 salary, 1099 contractor income (locums, moonlighting, expert witness work, honoraria), and sometimes K-1 income from a group or partnership. Each type is taxed and deducted differently.

Third, SSTB status. Medicine is a Specified Service Trade or Business under the tax code, which, as you will see, limits the popular 20% QBI deduction for high earners in a way that catches many doctors by surprise.

The single most important divide is employee versus owner. Since the 2017 tax law suspended unreimbursed employee business expenses, a purely W-2 physician generally cannot deduct scrubs, licensing, CME, or a home office against that salary. Owners and contractors can. That one rule shapes almost every strategy below.

If you are a W-2 employed physician

If your income is a single hospital or group W-2, your deduction menu is short, and most of the “doctor tax write-off” advice online quietly does not apply to you. What actually helps:

• Max your employer retirement plan. Contribute the full employee elective deferral to your 401(k) or 403(b), and capture any match. Many hospital systems also offer a 457(b) that lets you defer additional income; understand whether yours is governmental (safer) or non-governmental before piling in.
• Use an HSA if you have a high-deductible health plan. It is the only triple-tax-advantaged account: deductible going in, tax-free growth, tax-free for qualified medical costs.
• Do a backdoor Roth IRA. Physician income is almost always above the direct Roth limit, but the backdoor Roth (a non-deductible traditional IRA contribution converted to Roth) is a standard, legal workaround. Watch the pro-rata rule if you hold other pre-tax IRA money.
• Negotiate expense reimbursement. Because you cannot deduct CME, licensing, or society dues as an employee, the next best thing is to have your employer pay or reimburse them through an accountable plan or a CME stipend. That converts a non-deductible personal cost into a tax-free benefit.
• Consider creating legitimate 1099 income. This is the real unlock, covered next.

The theme for employed physicians is simple: your salary offers few deductions, so the leverage is in retirement accounts, pre-tax benefits, and, if you want the fuller deduction menu, adding self-employment income.

If you have 1099, locum, or moonlighting income

The moment you earn income as an independent contractor, you are running a business, and the deduction landscape opens up. Even a modest amount of locum or moonlighting income lets you deduct the ordinary and necessary costs of earning it. Because this is self-employment income, you also handle it on a business return, which is where clean business tax return preparation matters.

Commonly deductible against 1099 income:

• Continuing medical education, conference fees, and related travel and lodging
• State medical licenses, DEA registration, and board certification costs
• Professional society and specialty organization dues
• Malpractice insurance premiums you pay yourself (tail coverage included)
• Medical equipment, a laptop, and software used for the work (see Section 179 below)
• A home office used regularly and exclusively for the contracting work
• Mileage between work sites and to assignments (not your regular commute)
• Cell phone and internet, business-use portion
• Scrubs, medical bags, and required tools
• Licensing exam and credentialing fees

Two structural moves multiply the benefit:

• The self-employed health insurance deduction. If you pay your own health premiums and have net self-employment profit, you may deduct them above the line.
• Half of your self-employment tax. Contractors pay both halves of Social Security and Medicare, 15.3% up to the wage base, but the IRS lets you deduct the employer half of that tax.

Then there is the retirement lever. Self-employment income lets you open a Solo 401(k) and shelter a large share of your 1099 profit, on top of whatever you already contribute at your W-2 job (the employer-contribution limits are per-employer, though your personal elective deferral limit is shared across plans). This is often the single biggest reason to formalize even small amounts of contractor income.
A multi-state warning for locums. If you take assignments in states where you do not live, you generally owe income tax in each state where you earn, and you file a nonresident return there plus claim a credit at home. Physicians who travel for locum work are frequently surprised by multi-state filings, so track which state each dollar was earned in from day one.

If you own your practice

Practice owners have the fullest deduction profile of any physician, because nearly every cost of running the practice reduces taxable income. If you operate through a PLLC, PC, or S corporation, these run through the business:

• Staff wages, benefits, and the employer share of payroll taxes
• Office rent or, if you own the building, depreciation and property costs
• Medical and office supplies, disposables, and PPE
• Malpractice and business insurance
• Practice management software, EHR systems, and telehealth tools
• Marketing, website, and patient communications
• Professional fees for legal, accounting, and consulting help
• Equipment, expensed or depreciated (below)

For owner-physicians, three higher-leverage decisions sit on top of the everyday list.

Entity and reasonable compensation. Many practice owners operate as, or elect, an S corporation, because only W-2 wages are subject to the 15.3% payroll tax while distributions are not. The catch is that the IRS requires S-corp owners to pay themselves reasonable compensation for the work they do, and a low salary paired with large distributions is a top audit trigger. Getting the entity and payroll right is where corporate tax return preparation and reliable payroll processing earn their cost. If you are forming or restructuring an entity, remember the federal beneficial ownership rules and BOI reporting obligations that can apply.

Cash balance and defined benefit plans. For established, high-income owners who already max a 401(k), a cash balance plan can shelter an additional six figures per year, with contributions that rise with age. These are the heavy artillery of physician tax planning and are discussed below.

Family employment and the Augusta rule. Hiring your children for legitimate, age-appropriate work shifts income to their lower bracket. Renting your home to your practice for up to 14 days a year under the Augusta rule can produce a business deduction and tax-free personal income, if the meetings are real and documented. Both work only with market-rate pay and clean records.

The equipment deduction, updated for 2026 (OBBBA)

Whether you buy a portable ultrasound, exam-room equipment, imaging systems, or the computers your practice runs on, you can often deduct the cost quickly rather than over many years. OBBBA made the two main tools more generous and permanent.

• 100% bonus depreciation was permanently restored for qualifying property acquired and placed in service after January 19, 2025. There is no dollar cap, and it can create a loss.
• Section 179 expensing is capped at $2,560,000 for 2026 per IRS Rev. Proc. 2025-32, with the phase-out beginning above $4,090,000 of purchases. Unlike bonus, Section 179 cannot create a loss. Both are claimed on IRS Form 4562.

One caution that applies to every doctor: equipment must be placed in service, meaning operational, by December 31 to count this year, and depreciation is timing, not free money. Never buy equipment solely for the write-off. Buy what the practice needs, then let the deduction follow.

The QBI deduction, and why most physicians are phased out

This is the section most articles skip, and it matters. The Qualified Business Income (QBI) deduction under IRC §199A lets eligible pass-through owners deduct up to 20% of qualified business income, and OBBBA made it permanent. But medicine is a Specified Service Trade or Business, and for SSTBs the deduction phases out entirely above an income threshold.

• 2026 thresholds (per Rev. Proc. 2025-32): the phase-out begins at $403,500 of taxable income for married filing jointly and $201,750 for single filers, and the deduction is fully gone at $553,500 (MFJ) and $276,750 (single).

Since the average physician earns well into or above that range, most doctors get little or no QBI deduction on their 1099 or practice income by default. Here is the useful part: because the limit is based on taxable income, the strategies that lower it, above all large retirement contributions, can pull some physicians back under the threshold and restore part of the deduction. The interaction between retirement contributions, taxable income, and the QBI base is genuinely intricate, and it is exactly the kind of multi-variable calculation a physician-savvy CPA should run for you rather than something to eyeball. The honest takeaway: do not assume you get the 20%, and do not assume you never can. It depends on numbers worth modeling.

Retirement plans, the biggest lever for high earners

For high-income physicians, tax-deferred retirement plans are the most powerful legal deduction available, and industry data has long suggested fewer than a quarter of doctors use them to the fullest.

• SEP-IRA: up to 25% of compensation, capped at $72,000 for 2026. Simple, but less flexible than a Solo 401(k).
• Solo 401(k): for self-employment income, a total limit of $72,000 in 2026 ($80,000 with the age-50 catch-up), with the employee deferral portion at $24,500. See the IRS one-participant 401(k) rules. Note the SECURE 2.0 change: from 2026, catch-up contributions for higher earners must be made as Roth.
• Cash balance / defined benefit plan: the heavy artillery. For an established, high-income owner, contributions are actuarially set and rise with age, reaching well into six figures per year and all deductible to the business. They require annual actuarial work and a multi-year commitment, so they suit stable, high-profit practices.

The strategic point ties the whole guide together: a large pre-tax retirement contribution lowers this year’s tax, builds wealth, and can help a physician cross back under the QBI threshold. That is three wins from one decision.

Worked example: Dr. James Okafor

Dr. Okafor is a hospitalist. He earns a $340,000 W-2 salary and picks up locum tenens shifts that pay him $60,000 as a 1099 contractor. He and his spouse file jointly.

• On his W-2 income, his deductions are limited. He maxes his employer 403(b) and the match, uses his hospital’s HSA, and he and his spouse each do a backdoor Roth. He cannot deduct his CME or license against the salary, so he asks HR to reimburse CME through a stipend.
• On his $60,000 of locum income, everything changes. He deducts his malpractice tail coverage, DEA and state license fees, CME and travel tied to the contract work, a home office used only for locum scheduling and charting, mileage to assignments, and the business-use share of his phone. He also deducts the self-employed health insurance he pays and half of his self-employment tax.
• He opens a Solo 401(k) for the locum business and makes a substantial employer contribution from the 1099 profit, sheltering a large chunk of that $60,000.
• On QBI, his taxable income lands near the 2026 married-filing-jointly threshold of $403,500. Left alone, his SSTB status would phase out most of the deduction. By funding the Solo 401(k) and reviewing whether a small cash balance contribution makes sense, his CPA models whether he can pull taxable income under the threshold to reclaim part of the 20% on his locum income.
• On state taxes, two of his locum assignments were out of state, so he files nonresident returns there and claims a credit at home.

No single move here is exotic. The lesson is that the same doctor, taxed two ways, gets two very different results, and the $60,000 of contractor income is what unlocks the deductions and the extra retirement space. A return prepared without formalizing that side income would have quietly cost him thousands.

Advanced and often-missed moves

• Backdoor Roth IRA: standard for high earners; mind the pro-rata rule.
• PTET / SALT workaround: many states let a pass-through entity pay state income tax at the entity level, restoring a federal deduction around the SALT cap. Confirm Illinois specifics with your CPA.
• HSA: the most tax-efficient account available; fund it fully if eligible.
• Student loan interest, honestly: the $2,500 deduction phases out at incomes most attendings exceed, so it usually helps residents and early-career doctors, not established ones.
• Vehicle: business mileage for contracting or between practice sites is deductible; commuting is not; track it contemporaneously.
• Cost segregation: if you own your practice building, a study can accelerate depreciation on components.
• Real estate professional status: in dual-income households, a non-physician spouse who materially participates in rental real estate can sometimes unlock large deductions against the couple’s income. This is heavily scrutinized, so document participation carefully.

Audit triggers physicians should avoid

• An unreasonably low S-corp salary paired with large distributions.
• Aggressive home-office or Augusta-rule claims without documentation.
• 1099 income reported without the matching deductions, or personal costs run as business.
• Round-number deductions with no receipts or logs.
• Missing state returns for out-of-state locum work.

The defense in every case is the same: contemporaneous records, consistent categories, a business bank account kept separate from personal spending, and a rationale written down before, not after, the IRS asks.

Year-end tax checklist for physicians

• Confirm employer retirement contributions are maxed and any match captured.
• Fund the HSA and complete backdoor Roth conversions before deadlines.
• For 1099 income, tally deductions and confirm Solo 401(k) contributions.
• Review whether a cash balance plan makes sense for the year.
• Verify quarterly estimated payments are current to avoid penalties.
• Confirm reasonable compensation if you run an S corporation.
• Gather CME, license, DEA, and malpractice records.
• Reconcile any out-of-state locum income for multi-state filing.
• Project your QBI position and decide whether extra retirement funding preserves it.
• Schedule a planning meeting before December; most levers close at year-end.

Frequently Asked Questions

1. What tax deductions can physicians claim?

It depends on how you are paid. W-2 employed physicians can deduct very little against their salary since the 2017 law suspended unreimbursed employee expenses. Physicians with 1099, locum, or practice income can deduct CME, licensing, DEA registration, malpractice premiums they pay, home office, mileage, equipment, self-employed health insurance, and retirement contributions.

2. Can an employed (W-2) doctor deduct CME, licenses, or scrubs?

Generally no, not against W-2 wages. The better options are to have your employer reimburse those costs through an accountable plan or stipend, or to earn 1099 income against which they become deductible.

3. How does 1099 or locum tenens income help my taxes?

It turns you into a business owner for that income, which opens the full deduction menu and lets you open a Solo 401(k) to shelter a large share of the profit. Even modest locum income can unlock meaningful deductions.

4. Do physicians qualify for the 20% QBI deduction?

Usually not by default. Medicine is a Specified Service Trade or Business, so the deduction phases out above $403,500 of taxable income for joint filers and $201,750 for single filers in 2026, and disappears at $553,500 and $276,750. Reducing taxable income, mainly through retirement contributions, can restore part of it.

5. Should a physician practice be an S corporation?

Sometimes. An S corp can reduce self-employment tax because distributions are not subject to it, but you must pay reasonable compensation, and it adds payroll and a separate return. Whether it helps depends on your income and structure, so model it with a CPA.

6. What retirement plans give doctors the biggest deduction?

For self-employment income, a Solo 401(k) allows up to $72,000 in 2026, more with catch-up. High-income practice owners can add a cash balance or defined benefit plan to shelter six figures annually. Contributions reduce taxable income and can help preserve QBI.

7. Is malpractice insurance tax deductible?

Yes, if you pay it yourself as a contractor or practice owner, including tail coverage. If your employer provides it, there is nothing for you to deduct.

8. Can physicians deduct a home office?

Only if you use the space regularly and exclusively for business, and generally only against self-employment or practice income, not a W-2 salary. Occasional charting at home does not qualify.

9. How do taxes work for locum tenens physicians in multiple states?

You generally owe tax in each state where you earn income and file nonresident returns there, then claim a credit in your home state. Track which state each assignment’s income came from to avoid missed filings and penalties.

10. Can I put my kids on payroll to save taxes?

If you own the practice and the work is genuine and age-appropriate at a market wage, yes. Wages are deductible to the business and can be largely tax-free to the child up to the standard deduction. Document the role and keep timesheets.

11. Can high-income doctors still use a Roth IRA?

Directly, usually not, because of income limits. But the backdoor Roth, a non-deductible traditional IRA contribution converted to Roth, is a standard workaround. Watch the pro-rata rule if you hold other pre-tax IRA balances.

12. Can physicians deduct medical equipment right away?

Often yes. Under Section 179 (up to $2,560,000 in 2026) or 100% bonus depreciation, made permanent by OBBBA, you can deduct qualifying equipment in the year it is placed in service rather than depreciating it over years.

13. Is student loan interest deductible for doctors?

The $2,500 deduction phases out at incomes most attending physicians exceed, so in practice it usually benefits residents and early-career doctors rather than established high earners.

Key takeaways

• How you are paid decides what you can deduct. W-2 salary offers little; 1099 and practice income open the full menu.
• Legitimate self-employment income is the unlock, and it also creates room for a Solo 401(k).
• OBBBA kept 100% bonus depreciation and the 20% QBI deduction permanent and raised Section 179 to $2,560,000 for 2026, but medicine is an SSTB, so most physicians must manage taxable income to see any QBI.
• Retirement plans are the biggest lever for high earners, and cash balance plans can shelter six figures.
• Documentation and clean entities are your audit defense. When in doubt, work with a CPA who knows physicians.
