The Physician Tax Planning Playbook: 15 Strategies to Save $20K–$100K

If you have 1099 income from locum tenens, consulting, expert witness work, or a private practice operating as a sole proprietorship, you're paying 15.3% self-employment tax on every dollar of net profit. The S-Corp election lets you split income into a reasonable salary (subject to payroll tax) and distributions (not subject to SE tax). For a physician earning $300,000 in 1099 income with a $150,000 reasonable salary, the SE tax savings alone are approximately $18,000–$23,000 per year.

The legal entity you choose — sole proprietorship, single-member LLC, multi-member LLC, S-Corp, C-Corp, or hybrid structures — determines your tax obligations, liability exposure, and planning flexibility. Many physicians are operating under the wrong entity type. A private practice structured as a C-Corp, for example, faces double taxation that an S-Corp avoids. A physician with both W-2 and 1099 income may benefit from a separate LLC for side income. Entity optimization is foundational — every other strategy depends on getting this right.

Cash-basis taxpayers (most physicians) can control when income is recognized. If you expect lower income next year — perhaps due to a sabbatical, practice transition, or maternity/paternity leave — deferring December billings to January can shift income into a lower-bracket year. Conversely, if tax rates are expected to rise, accelerating income into the current year may save money. For practice owners, this also includes timing of equipment purchases, bonus depreciation elections, and prepayment of deductible expenses.

If you have any 1099 income or practice income and use a dedicated space in your home regularly and exclusively for business, you qualify for the home office deduction. This includes a portion of rent/mortgage interest, utilities, insurance, repairs, and depreciation. The simplified method allows $5/sq ft up to 300 sq ft ($1,500 max), but the actual expense method typically yields much larger deductions — especially for physicians in high-cost housing markets. The home office also unlocks the ability to deduct commuting mileage to other work locations.

Practice owners can establish an accountable plan — a formal written policy — that allows the practice to reimburse owners and employees for legitimate business expenses tax-free. This includes cell phone, internet, professional subscriptions, CME expenses, professional attire, and more. Unlike employee business expense deductions (which were eliminated by TCJA), accountable plan reimbursements are deductible by the business and tax-free to the recipient. This is one of the most underutilized strategies for S-Corp physician-owners.

Continuing medical education, medical conferences, board certification fees, medical licenses, professional society dues (AMA, specialty societies), medical journals, and work-related travel are all deductible for physicians with 1099 or practice income. For W-2 physicians, these deductions were suspended by TCJA through 2025 — but some states still allow them, and physicians with any side income can deduct the business-related portion on Schedule C. Locum tenens physicians can also deduct travel, lodging, and meals while on assignment.

Physicians with 1099 income can contribute up to $70,000 (2026) to a Solo 401(k) — $23,500 as employee deferral plus up to 25% of net self-employment income as employer contribution. If you're 50+, add a $7,500 catch-up. The Solo 401(k) is superior to the SEP-IRA for most physicians because it allows employee deferrals (enabling higher contributions at lower income levels) and offers a Roth option. For a physician in the 37% bracket, a $70,000 contribution saves $25,900 in federal tax alone.

The cash balance plan is the secret weapon of high-income physicians. It's a defined benefit plan that allows annual contributions of $100,000–$250,000+ depending on your age (older = higher limits). When stacked on top of a 401(k), a 50-year-old physician can potentially shelter $300,000+ per year from current taxation. The trade-off: mandatory annual contributions, higher setup and administration costs ($2,000–$5,000/year), and a 5-year commitment is typical. But for physicians earning $400,000+ who want aggressive tax reduction, nothing else comes close.

The backdoor Roth IRA lets high-income physicians contribute $7,000/year (2026) to a Roth IRA regardless of income by making a non-deductible traditional IRA contribution and converting it. The mega backdoor Roth — available through certain 401(k) plans — allows up to $46,500 in additional after-tax contributions that can be converted to Roth. Over a 20-year career, the tax-free growth on these Roth contributions can be worth $500,000–$2,000,000+ in retirement.

When you purchase rental property, you can depreciate the building (not the land) over 27.5 years for residential or 39 years for commercial. A cost segregation study accelerates this by reclassifying components (appliances, carpeting, landscaping, electrical) into 5, 7, or 15-year categories — generating massive first-year depreciation deductions. A $500,000 rental property can generate $100,000–$150,000 in first-year depreciation through cost segregation, which translates to $37,000–$55,000 in tax savings for a physician in the 37% bracket.

Under IRS rules, rentals with an average guest stay of 7 days or less are not classified as passive rental activity — meaning the losses can offset your W-2 or active income without needing Real Estate Professional Status (REPS). This is the 'short-term rental loophole' and it's perfectly legal. Combined with cost segregation, a short-term rental property can generate significant paper losses that directly reduce a W-2 physician's taxable income. This is one of the most powerful strategies for employed physicians who cannot qualify for REPS.

Qualified Opportunity Zone (QOZ) investments allow physicians to defer capital gains tax by reinvesting gains into designated opportunity zones. If held for 10+ years, any appreciation on the QOZ investment is permanently tax-free. While the initial step-up basis benefits expired, the 10-year exclusion on appreciation remains powerful for physicians with significant realized capital gains. This strategy pairs well with practice sale proceeds or large stock liquidations.

Physicians with 1099 income, K-1 income, or investment income must make quarterly estimated tax payments to avoid underpayment penalties. The safe harbor rule requires paying either 110% of prior-year tax liability or 90% of current-year liability. Many physicians overpay estimates, giving the IRS an interest-free loan, or underpay and face penalties of 8%+ in the current interest rate environment. We model quarterly estimates precisely to minimize both penalties and opportunity cost.

Every tax strategy in this playbook must be properly documented to withstand IRS scrutiny. This includes written accountable plans, reasonable compensation studies for S-Corp owners, contemporaneous mileage logs, home office measurements and photos, real estate participation time logs, and proper basis tracking for retirement accounts. We prepare audit-ready documentation for every strategy we implement — not because we expect an audit, but because documentation is what separates a legal tax strategy from a tax problem.

Physicians who practice in multiple states (common for locum tenens), live in a different state than they work, or are considering relocation face complex state tax obligations. Some states have no income tax (Texas, Florida, Nevada, Tennessee, Wyoming, Washington, New Hampshire). Others have high rates (California 13.3%, New York City 12.7%+ combined). For physicians earning $500,000+, state tax planning — including practice entity domicile, residency planning, and multi-state allocation — can save $15,000–$30,000+ annually.
