Tax Planning for Orthopedic Surgeons

S Corp strategy, FICA savings on practice income, the QBI deduction trap for physicians, and quarterly estimated tax planning — with specific numbers for surgeons earning $600K–$1.5M.

The tax picture at orthopedic surgeon income levels

At the incomes orthopedic surgeons earn, federal income tax alone isn't the whole picture. Add FICA, the Additional Medicare Tax, and state income tax, and many surgeons face marginal rates of 48–55 cents on every additional dollar earned in peak earning years.

Here's the stack on a typical $800,000 of professional income for a private practice surgeon in a moderate-tax state:

The Medicare tax is the one most surgeons underestimate. Unlike Social Security, there is no cap: 2.9% applies to every dollar of self-employment income, plus an additional 0.9% on income above the thresholds. On $1M of professional income, that's $29,000 in Medicare taxes alone — before the Additional Medicare Tax surcharge. An S Corporation structure can reduce this significantly.

S Corp structure for private practice surgeons

An S Corporation election is the most commonly recommended entity-level tax strategy for physician practice owners. It applies to private practice surgeons, solo practitioners, and partners who receive 1099 or pass-through practice income. It does not reduce taxes on hospital W-2 salary — that income is already on a payroll system and FICA is fully applied.

How it works

A professional limited liability company (PLLC) or professional corporation (PC) that elects S Corp tax treatment pays its physician-owner a W-2 salary. The remaining practice profit — after expenses and salary — passes through as a distribution. That distribution avoids both Social Security tax and Medicare payroll tax. The owner still pays income tax on distributions, but not self-employment or payroll FICA taxes.

The "reasonable compensation" requirement

The IRS requires that S Corp physician-owners pay themselves a "reasonable salary" — roughly what they would pay a comparable employee for the same work. For orthopedic surgeons, reasonable compensation is typically in the range of $150K–$250K as a W-2 salary, depending on specialty and hours — the rest of the clinical income can flow as distributions. Setting the salary artificially low (below $100K) invites IRS scrutiny. A CPA with physician-practice experience can advise on the appropriate range for your subspecialty.

The § 199A QBI deduction: why most high-earning ortho surgeons don't qualify

The Qualified Business Income (QBI) deduction under IRC § 199A allows eligible business owners to deduct up to 20% of qualified business income. It was made permanent by the One Big Beautiful Bill Act (OBBBA, July 2025).⁴

The catch: medical practices are classified as a Specified Service Trade or Business (SSTB) under § 199A(d)(1)(A). SSTBs phase out of the deduction faster as income rises. For 2026, the deduction is completely eliminated for SSTB owners with taxable income above:

• $272,300 for single filers
• $544,600 for married filing jointly

OBBBA expanded the phaseout range (from $50K to $75K for single filers; $100K to $150K for joint filers), so the phase-out now begins at $197,300 (single) and $394,600 (MFJ).⁴ The practical implication: most orthopedic surgeons with income above $300K (single) or $600K (MFJ) receive zero QBI deduction on their medical practice income.

One new 2026 wrinkle: OBBBA added a minimum $400 QBI deduction for taxpayers with at least $1,000 in qualified business income who actively participate in the business. This is a floor, not a meaningful planning lever at attending income levels — but it's worth noting for residents or fellows with any business income.

Quarterly estimated taxes for high-earning surgeons

For surgeons who receive S Corp distributions, partnership income, or any significant 1099 income, payroll withholding won't cover the full tax bill. Underpayment results in IRS penalties. The solution is quarterly estimated tax payments.

Safe harbor rules

The IRS won't penalize underpayment if you've paid at least one of the following through withholding and estimated payments:

• 100% of last year's tax liability (if prior-year AGI was ≤$150K)
• 110% of last year's tax liability (if prior-year AGI exceeded $150K — which applies to virtually all attending orthopedic surgeons)

For first-year attendings transitioning from a residency or fellowship where tax liability was low, the safe harbor is easy to hit: just pay more than 110% of the prior year's (lower) tax bill. Use that year to set up a solid withholding/estimated payment structure, then recalibrate once you have a full attending year's return to anchor from.

For surgeons with variable procedural income, paying 110% of the prior year's tax spread across four payments eliminates underpayment risk while preserving cash flow flexibility.

Getting the structure right: when to act

Entity elections and payroll setups have timing constraints. S Corp elections must generally be filed by March 15 of the tax year for which you want them to apply (Form 2553), though late-election relief is often available. A few practical milestones:

• Year 1 as attending: Prioritize setting up quarterly estimated tax payments. Even if your employer is withholding, account for any side income, moonlighting, expert witness, or distribution income.
• Year 2–3: If you're on a private practice track with meaningful 1099 or pass-through income, evaluate the S Corp election. The math generally favors S Corp for surgeons earning over $400K in pass-through income.
• Year 3–5 (partnership track): As you move from associate to partner, revisit the entity layer. Partnership income is treated differently from S Corp income for payroll tax purposes. Some groups operate as partnerships; others as S Corps at the individual surgeon level. Your setup matters for both FICA and retirement plan contribution capacity.
• Any year you add significant 1099 income (ASC distributions, medical directorship fees, expert witness work): reassess whether standalone quarterly payments are sufficient or whether an entity structure change makes sense.

The retirement savings layer — Solo 401(k) with profit-sharing, cash balance plan, backdoor Roth — sits on top of the entity structure. See the retirement planning guide for a full breakdown of the four tax-advantaged vehicles and how much each saves at orthopedic surgeon income levels.
