Physician Tax Deductions:
The Definitive Guide for 2026
Tax deductions for doctors depend on how you earn your income. Compare W-2, 1099, and S-Corp treatment, with expense categories and records to discuss with your CPA.
Quick Answer
Physician tax deductions depend on how you are paid. W-2 physicians are mostly limited to retirement deferrals, HSA contributions, and itemized deductions, because unreimbursed employee expenses are not deductible. 1099 and S-Corp physicians can also deduct business expenses like malpractice insurance, CME, home office, and health insurance premiums, plus far higher retirement contributions.
Physician Tax Deduction Overview
Your Employment Type Determines Everything
Tax deductions for doctors depend on how you earn your income: as a W-2 employee, a 1099 independent contractor, or through an S-Corporation. Start with your employment arrangement, then separate personal costs from expenses connected to your medical work.
This guide covers every major tax deduction available to physicians in 2026, organized by employment type, with specific dollar limits, eligibility rules, and real-world examples. Whether you are a hospital-employed cardiologist, a locum tenens physician, or a private practice owner operating through an S-Corp, you will find actionable strategies to reduce your tax burden legally and substantially.

Potential annual savings with full strategy
The single biggest factor in your deduction strategy is your employment classification. W-2 physicians have limited deduction options since the TCJA eliminated unreimbursed employee expenses. 1099 and S-Corp physicians unlock an entirely different universe of deductions, business expenses, home office, health insurance premiums, and dramatically higher retirement contribution limits.
W-2 Physician Deductions
What Employed Physicians Can (and Cannot) Deduct
If you are employed by a hospital, health system, or practice group and receive a W-2, your deduction options are more limited than your self-employed colleagues. The Tax Cuts and Jobs Act eliminated the miscellaneous itemized deduction for unreimbursed employee expenses, which means you can no longer deduct scrubs, CME, licensing fees, or professional dues on your personal return. However, several powerful deductions remain available.
Retirement Contributions: 401(k) and 403(b)
2026 Contribution Limits
| Component | Under 50 | Age 50-59 / 64+ | Age 60-63 |
|---|---|---|---|
| Employee Deferral | $24,500 | $24,500 | $24,500 |
| Catch-Up Contribution | $0 | $8,000 | $11,250 |
| Total Employee Contribution | $24,500 | $32,500 | $35,750 |
| Employer Match (typical) | Up to $47,500 | Up to $47,500 | Up to $47,500 |
| Maximum Total (415 limit) | $72,000 | $80,000 | $83,250 |
| Tax Savings at 37% (deferral only) | $9,065 | $12,025 | $13,228 |
Most hospital-employed physicians have access to a 403(b) plan with the same limits. Some also have access to a governmental 457(b), which allows an additional $24,500 in deferrals, effectively doubling your pre-tax retirement savings.
Health Savings Account (HSA)
2026 HSA Limits
- Individual coverage: $4,400 (2026 limit)
- Family coverage: $8,750 (2026 limit)
- Catch-up contribution (age 55+): additional $1,000
- Triple tax advantage: tax-deductible contributions, tax-free growth, tax-free withdrawals for qualified medical expenses
- Requires enrollment in a high-deductible health plan (HDHP)
- No income phase-out, available to physicians at any income level
The HSA is the only account in the tax code with a triple tax benefit: tax-deductible going in, tax-free growth, and tax-free coming out (for medical expenses). For high-income physicians, maximize your HSA every year and invest it for long-term growth. Pay current medical expenses out of pocket and let the HSA compound. At retirement, you can withdraw for any purpose (taxed like a traditional IRA) or tax-free for medical expenses.
Other W-2 Deductions
| Deduction | 2026 Limit | Notes |
|---|---|---|
| Student Loan Interest | $2,500 max | Phases out at $80K-$95K (single) / $165K-$195K (MFJ). Most attendings are over the limit. |
| Charitable Contributions | Up to 60% of AGI (cash) | Itemize to deduct. Consider donor-advised funds for bunching strategy. |
| SALT (State & Local Taxes) | $40,400 cap (2026) | Includes state income + property taxes. Phases down for MAGI above $505,000 to a floor of $10,000. Painful for high-tax states. |
| Mortgage Interest | On first $750K of debt | Deductible if you itemize. Applies to primary residence + one second home. |
| Medical Expenses | Exceeding 7.5% of AGI | Rarely helpful for high-income physicians, floor is too high. |
| Educator Expenses | $300 (if applicable) | Only for K-12 teachers. Not applicable to physician educators. |
| 457(b) Deferral | $24,500 additional | If your employer offers a governmental 457(b), you can defer an additional $24,500 pre-tax, on top of your 403(b). |
The Unreimbursed Employee Expense Trap
Prior to 2018, W-2 physicians could deduct unreimbursed business expenses (CME, licensing, scrubs, professional dues) as miscellaneous itemized deductions subject to a 2% AGI floor. The TCJA suspended this deduction, and the OBBBA did not restore it. These expenses are NOT deductible for W-2 physicians in 2026. If your employer does not reimburse them, you absorb the cost. The solution: ask your employer for an accountable plan, or generate 1099 income and deduct business expenses against that income.
1099 Physician Tax Deductions
The Full Universe of Business Expense Write-Offs
If you earn 1099 income, from locum tenens, consulting, expert witness work, telemedicine, or private practice, you unlock an entirely different tier of tax deductions. These are above-the-line business deductions reported on Schedule C (sole proprietorship) or through your S-Corp. They reduce your taxable income and your self-employment tax base.
Business Expense Deductions
Home Office Deduction
$1,500-$5,000+Simplified method: $5/sq ft up to 300 sq ft ($1,500 max). Actual expense method: proportional share of mortgage/rent, utilities, insurance, repairs, depreciation. Requires regular and exclusive use of a dedicated space for business.
Full home office guideMalpractice Insurance
$5,000-$50,000+Professional liability (malpractice) insurance premiums are fully deductible. Costs vary dramatically by specialty: $5,000-$10,000 for psychiatry, $20,000-$50,000+ for surgical specialties. Tail coverage premiums are also deductible.
CME / Continuing Medical Education
$2,000-$5,000+Conference registration fees, online CME courses, medical journal subscriptions, medical textbooks and reference materials, board review courses, and specialty recertification costs. All deductible as ordinary and necessary business expenses.
Licensing, DEA & Professional Dues
$500-$2,000+State medical license fees, DEA registration ($888 for 3 years), board certification fees, AMA/specialty society dues, hospital credentialing costs, and state controlled substance registration fees.
Business Travel
$3,000-$15,000+Airfare, hotel, rental car, and 50% of meals for locum tenens assignments, CME conferences, and travel between practice locations. Must be away from your tax home overnight. Commuting is never deductible.
Business travel deduction guideScrubs, Equipment & Supplies
$500-$3,000+Scrubs (not suitable for everyday wear), stethoscopes, medical instruments, surgical loupes, computer and software for business use, medical bag and supplies, and protective equipment.
Health Insurance Premiums
$8,000-$30,000+Self-employed physicians can deduct 100% of health insurance premiums for themselves, spouse, and dependents, as an above-the-line deduction. This includes medical, dental, and vision insurance, plus long-term care insurance (age-based limits).
Professional Services
$2,000-$10,000+CPA/tax preparation fees, legal fees for business matters, bookkeeping services, financial planning fees (if business-related), practice management consulting, and billing service fees.
Retirement Contributions for Self-Employed Physicians
Self-employed physicians have access to dramatically higher retirement contribution limits compared to W-2 employees. The Solo 401(k) is the gold standard for maximizing pre-tax retirement savings.
| Plan Type | 2026 Max Contribution | Best For | Key Feature |
|---|---|---|---|
| Solo 401(k) | Up to $72,000 | Self-employed with no employees | Highest contribution limits; Roth option available |
| Solo 401(k) + Catch-up (50+) | Up to $80,000 | Self-employed, age 50+ | $8,000 additional catch-up contribution |
| Solo 401(k) + Catch-up (60-63) | Up to $83,250 | Self-employed, age 60-63 | $11,250 enhanced catch-up (SECURE 2.0) |
| SEP IRA | Up to $72,000 (25% of comp) | Simple setup, employer-only contributions | No employee deferral; easier administration |
| Cash Balance Pension Plan | $100,000-$300,000+ | High-income physicians over 40 | Dramatically higher limits based on age; pairs with Solo 401(k) |
| Defined Benefit Plan | Actuarially determined | Consistent high income | Highest possible contributions; complex administration |
For a physician earning $400,000 in 1099 income through an S-Corp, contributing $72,000 to a Solo 401(k) reduces taxable income to $328,000, saving approximately $25,200 in federal taxes at an assumed 35% marginal rate (a single filer in the 2026 35% bracket). Add a cash balance plan and you can shelter an additional $100,000+, potentially saving $60,000+ in taxes while building retirement wealth rapidly. See our QBI deduction guide for how retirement contributions also increase your Section 199A deduction.

S-Corp Specific Strategies
Accountable Plan, Salary Optimization & Beyond
Physicians operating through an S-Corporation gain access to additional deduction strategies that sole proprietors and W-2 employees cannot use. The S-Corp is not just about self-employment tax savings, it is a deduction amplifier when structured correctly.
The Accountable Plan: Your Tax-Free Reimbursement Engine
An accountable plan allows your S-Corp to reimburse you for legitimate business expenses tax-free. The reimbursement is a deductible expense for the S-Corp and is not reportable as income on your W-2 or personal return. This is one of the most powerful and underutilized strategies for physician S-Corp owners.
Expenses You Can Reimburse Through an Accountable Plan:
A well-structured accountable plan can generate $10,000-$25,000+ in annual tax-free reimbursements for a typical physician S-Corp owner. The key requirements are: (1) expenses must have a business connection, (2) expenses must be substantiated with documentation within 60 days, and (3) excess reimbursements must be returned within 120 days. Without an accountable plan, most of these expenses are either non-deductible or create taxable income.
Reasonable Salary Optimization
The S-Corp requires you to pay yourself a reasonable salary as a W-2 employee of your own corporation. Income above your salary flows through as distributions, which are exempt from self-employment (FICA) tax. The optimization challenge: set your salary high enough to satisfy the IRS, but low enough to maximize tax savings on distributions.
| Factor | Impact |
|---|---|
| Higher Salary | More FICA tax paid, lower distributions, but more defensible and higher 401(k) employer match ceiling |
| Lower Salary | Less FICA tax, higher distributions, but greater IRS audit risk for unreasonable compensation |
| FICA Savings | ~15.3% on first $168,600 (2026); 2.9% Medicare on all wages above |
| QBI Interaction | Lower salary = higher QBI (pass-through profit). See our QBI guide for the tradeoff analysis. |
| Optimal Range | Typically 40%-60% of net income for most physician S-Corps; depends on specialty and BLS data |
The salary-vs-distribution split is the single most impactful tax decision for physician S-Corp owners. Setting it correctly can save $15,000-$30,000+ per year in FICA taxes alone, plus additional savings through the QBI deduction. Setting it incorrectly, either too low (audit risk) or too high (overpaying tax), costs thousands annually. We model this for every client. Read our full S-Corp election guide.
W-2 vs 1099 vs S-Corp Deduction Matrix
Side-by-Side Comparison of Every Major Deduction
This is the comprehensive comparison showing which deductions are available under each employment type. Use this matrix to identify what you are missing and where a structural change could unlock significant savings.
| Deduction | W-2 Employee | 1099 / Sole Prop | S-Corp Owner |
|---|---|---|---|
| 401(k) / 403(b) Deferral ($24,500) | Yes (employer plan) | Solo 401(k) | Solo 401(k) via S-Corp |

| Total Retirement (up to $72K) | Depends on employer plan | Yes (Solo 401k) | Yes (Solo 401k via S-Corp) |
| Cash Balance / DB Plan | No (employer decision) | Yes | Yes |
| HSA ($4,400 / $8,750) | Yes | Yes | Yes |
| Home Office | No | Yes | Yes (via accountable plan) |
| Malpractice Insurance | No (employer pays) | Yes | Yes (S-Corp deduction) |
| CME / Continuing Education | No (unless employer reimburses) | Yes | Yes (accountable plan) |
| Licensing / DEA Fees | No (unless employer reimburses) | Yes | Yes (accountable plan) |
| Business Travel | No (unless employer reimburses) | Yes | Yes (accountable plan) |
| Scrubs / Equipment | No | Yes | Yes (accountable plan) |

| Student Loan Interest ($2,500) | Yes (income limits apply) | Yes (income limits apply) | Yes (income limits apply) |
| Charitable Contributions | Yes (itemize) | Yes (itemize) | Yes (itemize) |
| SALT ($40K cap MFJ) | Yes (itemize) | Yes (itemize) | Yes + PTE tax election in some states |
| SE Tax Savings on Distributions | N/A | No | Yes (primary S-Corp benefit) |
| QBI Deduction (up to 20%) | No (W-2 income excluded) | Yes (SSTB limits) | Yes (SSTB limits, salary tradeoff) |
| Accountable Plan Reimbursements | N/A (employer option) | N/A | Yes |
| Cell Phone / Internet (business %) | No | Yes | Yes (accountable plan) |
| Professional Dues / Subscriptions | No | Yes | Yes (accountable plan) |
The Green Column Tells the Story
Notice how the S-Corp column is almost entirely "Yes." This is why we recommend the S-Corp election for most physicians with $100,000+ in 1099 income. It unlocks the most deductions, the best retirement options, and the FICA tax savings that sole proprietorships cannot match. But the S-Corp requires proper setup: payroll, reasonable salary, accountable plan, and ongoing compliance. It is not a DIY strategy.
Illustrative Example: A Locum Anesthesiologist Restructures
A hypothetical sole proprietor moves to an S-Corp with full deduction tracking
Illustrative example (hypothetical, not a client result)
A Hypothetical Anesthesiologist, Age 45, Married Filing Jointly
Full-time locum tenens with about $480,000 of gross 1099 income, filing as a sole proprietor with minimal expense tracking. Two children.
Before and After: What Changes
| Lever | Before: Sole Proprietor | After: S-Corp + Full Strategy |
|---|---|---|
| Entity and payroll tax | All net profit subject to self-employment tax | Reasonable salary through payroll; remaining profit paid as distributions, which are not subject to FICA |
| Retirement | Modest SEP IRA contribution | Solo 401(k): employee deferral plus employer profit sharing, up to the combined annual limit |
| HSA | Not used | Family HSA funded each year |
| Accountable plan | None | Home office, CME travel, licensing and DEA fees, phone, internet, equipment, and mileage reimbursed tax-free by the S-Corp |
| Health insurance | Deducted inconsistently | Premiums paid by the S-Corp, included in W-2 wages, then taken as the self-employed health insurance deduction |
| Business expenses | Minimal tracking | Malpractice, professional services, and other ordinary expenses tracked and claimed |
| QBI deduction | Not analyzed | Modeled each year; medicine is a specified service business, so the deduction phases out as taxable income rises |
| Charitable giving | Annual checks | Gifts bunched through a donor-advised fund in itemizing years |
2026 reference points: the Solo 401(k) employee deferral is $24,500 and the combined employee plus employer limit is $72,000 for someone under 50. For married couples filing jointly, the QBI deduction for a specified service business phases out between $403,500 and $553,500 of taxable income.
Illustrative example (hypothetical, not a client result). We do not show a savings total because the dollar result depends on the salary set, state of residence, deductions already being claimed, and other facts. Retirement contributions defer tax rather than eliminate it. This is educational, not individualized tax advice, and no specific savings are guaranteed.
The improvement in this example comes from five levers working together: (1) payroll tax savings on S-Corp distributions, (2) a fully funded Solo 401(k), (3) accountable plan reimbursements, (4) tracking expenses that were previously missed, and (5) whatever QBI deduction the household's taxable income allows. No single lever does the work; the combination does.

Common Deduction Mistakes Physicians Make
Costly Errors We See Every Tax Season
Mistake #1: Not tracking business expenses throughout the year
Many physicians wait until tax time to gather receipts and realize they cannot substantiate deductions. Use a dedicated business bank account and credit card, and categorize expenses monthly. The deductions you cannot document are deductions you cannot take.
Mistake #2: Claiming unreimbursed employee expenses as a W-2 physician
This deduction was suspended by the TCJA in 2018. We still see W-2 physicians (and some CPAs) claiming CME, licensing, and scrubs as miscellaneous itemized deductions. The IRS will disallow these and may flag your return for additional review.
Mistake #3: Missing the home office deduction entirely
Many self-employed physicians who do charting, billing, scheduling, or administrative work from a dedicated home space fail to claim the home office deduction. If you use a space regularly and exclusively for business, you qualify. The actual expense method can yield $3,000-$8,000+ annually.
Mistake #4: Under-contributing to retirement accounts
A physician contributing $24,500 to a Solo 401(k) when they could contribute $72,000 (with employer profit sharing) is leaving $47,500 in deductions, and about $17,575 in tax savings at a 37% marginal rate, on the table. Many physicians do not realize they can contribute as both employee and employer to a Solo 401(k).
Mistake #5: Operating as a sole proprietor instead of an S-Corp
Sole proprietors pay self-employment tax on 100% of net income. S-Corp owners pay FICA only on their reasonable salary. For a physician netting $300,000, this structure change alone can save $10,000-$20,000+ per year in FICA taxes, before considering accountable plan and QBI benefits.
Mistake #6: Not having an accountable plan for their S-Corp
An S-Corp without an accountable plan misses thousands in tax-free reimbursements. Many physician S-Corp owners pay for business expenses personally and never get reimbursed, losing the deduction entirely. Setting up an accountable plan takes minimal effort and delivers outsized tax savings.
Mistake #7: Ignoring state pass-through entity tax elections
Many states now offer PTE tax elections that allow S-Corps and partnerships to pay state income tax at the entity level, effectively bypassing the SALT deduction cap entirely. Even with the higher $40,400 cap for 2026 under OBBBA, high-income physicians whose cap phases down (MAGI above $505,000) or who owe more than $40,400 in state taxes can save $5,000-$15,000+ annually. Ask your CPA if your state offers this.
Deduction Checklist & Next Steps

- Categorize scrubs, equipment, and supply purchases
- Track business mileage with an app (MileIQ, Everlance)
4Entity & Structure
- Evaluate S-Corp election if 1099 income exceeds $100K
- Set up accountable plan for S-Corp expense reimbursements
- Set defensible reasonable salary (model with CPA)
- Check state PTE tax election availability
5Personal Deductions
- Evaluate standard vs. itemized deduction
- Bunch charitable contributions using donor-advised fund
- Deduct student loan interest (if under income limits)
- Claim SALT up to the $40,400 cap for 2026 (phases down for MAGI above $505,000)
The best time to optimize your deduction strategy is at the beginning of the tax year, not at tax time. Many of the most valuable strategies. S-Corp election, accountable plan setup, retirement plan establishment, HSA enrollment, must be in place before the expenses occur or contributions are made. If you are reading this mid-year, start now. Every month you delay costs you money.
