The QBI Deduction for Physicians:
Section 199A, Decoded
A 23% deduction on qualified business income — permanently extended and increased from 20% to 23% under the OBBBA. But for physicians, SSTB rules make this deduction one of the most misunderstood in the tax code.
What Is the QBI Deduction?
Section 199A Basics for Physicians
The Qualified Business Income (QBI) deduction under Section 199A of the Internal Revenue Code allows owners of pass-through businesses to deduct up to 23% of their qualified business income from their taxable income. Originally enacted by the Tax Cuts and Jobs Act of 2017 at 20%, this deduction was permanently extended and increased to 23% by the One Big Beautiful Bill Act (OBBBA) — making it a permanent feature of the tax code starting in 2026.
For a physician netting $200,000 in qualified business income through a pass-through entity, the QBI deduction could be worth up to $46,000 — saving $17,020 in federal taxes at the 37% marginal rate. But there is a major catch for physicians: your income is classified as a Specified Service Trade or Business (SSTB), which means the deduction phases out at certain income levels.

The QBI deduction applies only to income from pass-through entities (S-Corps, partnerships, sole proprietorships, LLCs). It does not apply to W-2 wages. If you are a physician employed by a hospital and receive only a W-2, your clinical income does not qualify for QBI. This deduction is for physicians with 1099 income, private practice owners, and those with side businesses.
Eligible Pass-Through Income Sources for Physicians
- Private practice income (sole proprietorship, partnership, or S-Corp)
- Locum tenens 1099 income through an LLC or S-Corp
- Medical consulting or expert witness fees
- Telemedicine side income
- Speaking fees and CME presentation income
- Medical device consulting or product royalties
- Course creation, coaching, or content creation businesses
The SSTB Problem for Physicians
Why Medicine Gets Penalized Under Section 199A
The IRS classifies health care as a Specified Service Trade or Business (SSTB) under Section 199A. This category includes physicians, dentists, pharmacists, nurses, and other health professionals whose principal asset is the reputation or skill of their employees or owners.
For non-SSTB businesses (manufacturing, real estate services, engineering), the QBI deduction is available at all income levels — subject only to the W-2 wage and capital limitations. But for SSTBs like physician practices, the deduction phases out entirely once taxable income exceeds certain thresholds.
2026 SSTB Phase-Out Thresholds
| Filing Status | Phase-Out Begins | Phase-Out Complete | Phase-Out Range |
|---|---|---|---|
| Single / HOH | $191,950 | $241,950 | $50,000 |
| Married Filing Jointly | $383,900 | $483,900 | $100,000 |
The Phase-Out Math Matters
The phase-out is a sliding scale, not a cliff. A physician MFJ with $433,900 in taxable income is exactly halfway through the phase-out range — they keep 50% of their QBI deduction. At $383,900 they keep 100%. At $483,900 they keep 0%. Every dollar of taxable income within this range reduces the available QBI deduction proportionally.
Why This Matters for Physician Income Levels
According to Medscape's 2025 Physician Compensation Report, the average physician earns $363,000 per year. Many specialties earn well above $500,000. This means most full-time physician practice owners are above the SSTB ceiling and receive zero QBI deduction on their medical practice income.
| Specialty | Average Income | MFJ QBI Status | QBI Available? |
|---|---|---|---|
| Primary Care | $277,000 | Below phase-out | Full or partial |
| Psychiatry | $306,000 | Near phase-out start | Partial (with planning) |
| Emergency Medicine | $373,000 | Near phase-out start | Partial (with planning) |
| Anesthesiology | $472,000 | In phase-out | Partial (shrinking) |
| Orthopedic Surgery | $612,000 | Above phase-out | None on medical income |
| Cardiology | $591,000 | Above phase-out | None on medical income |
| Neurosurgery | $788,000 | Well above phase-out | None on medical income |
Even high-income physicians above the SSTB ceiling can potentially access QBI through non-medical income streams operated in a separate entity. We cover this in the spin-off strategy section below.
QBI & S-Corp: The Critical Tradeoff
The Interaction Most Guides Miss
Here is the tension that most QBI guides — including those from major competitors — gloss over: the S-Corp election and the QBI deduction pull in opposite directions on the salary-vs-distribution split.
The S-Corp wants your salary low: The lower your W-2 salary, the more income flows through as distributions exempt from self-employment tax. That is the entire point of the S-Corp election.
QBI also wants your salary low: W-2 wages from your own S-Corp do not count as qualified business income. Every dollar of salary reduces your QBI, which reduces the 23% deduction.
So both strategies benefit from a lower salary. But the IRS demands a reasonable salary — set it too low and you face reclassification, penalties, and back taxes. The optimization question is: what is the salary that maximizes your total after-tax position considering both SE tax savings and QBI deduction?
For physicians inside the SSTB phase-out range, the QBI deduction adds $5,000 to $15,000+ in additional value on top of S-Corp SE tax savings. For those above the ceiling, QBI is zero and the only lever is S-Corp payroll tax optimization. Knowing which zone you are in changes the entire strategy.
Worked Example: Psychiatrist, MFJ, $360,000 Net Income
Scenario: Dr. Patel, Psychiatrist, MFJ, LLC taxed as S-Corp
Net practice income: $360,000. Spouse earns $40,000 W-2. Total household income: $400,000.
| Factor | Salary: $180K | Salary: $140K | Salary: $120K |
|---|---|---|---|
| S-Corp W-2 Salary | $180,000 | $140,000 | $120,000 |
| S-Corp Distribution | $180,000 | $220,000 | $240,000 |
| Qualified Business Income | $180,000 | $220,000 | $240,000 |
| Raw QBI Deduction (23%) | $41,400 | $50,600 | $55,200 |
| Taxable Income (approx) | $400,000 | $400,000 | $400,000 |
| SSTB Factor (MFJ) | 83.9% | 83.9% | 83.9% |
| Adjusted QBI Deduction | $30,204 | $36,916 | $40,272 |
| SE Tax Saved vs Sole Prop | $15,660 | $19,140 | $20,880 |
| QBI Tax Saved (37%) | $11,175 | $13,659 | $14,901 |
| Total Tax Benefit | $26,835 | $32,799 | $35,781 |
| IRS Risk Level | Low | Moderate | High |
The $140K salary option offers strong tax savings while maintaining defensible reasonable compensation for a psychiatrist. The $120K salary saves more but carries meaningful IRS risk — below BLS median for psychiatry.
The Reasonable Compensation Constraint
You cannot simply minimize your salary to maximize QBI. The IRS requires that S-Corp shareholder-employees receive reasonable compensation for services rendered. For a full-time psychiatrist, a $120,000 salary may be difficult to defend when BLS data shows a median of ~$260,000. The optimal salary balances tax savings against audit risk. Read our full S-Corp reasonable compensation analysis.
Worked Example: Orthopedic Surgeon, MFJ, $650,000 Net Income
Scenario: Dr. Kim, Orthopedic Surgeon, MFJ, Private Practice S-Corp
Net practice income: $650,000. Spouse does not work. Taxable income well above $483,900 MFJ ceiling.
| Factor | Value |
|---|---|
| Taxable Income | $650,000+ |
| SSTB Phase-Out | Complete (0% QBI) |
| QBI Deduction on Medical Income | $0 |
| S-Corp Strategy Focus | Pure SE tax savings |
| Optimal Play | Maximize distributions, set salary at defensible minimum |
| Potential Additional Strategy | Spin off non-medical income to separate non-SSTB entity |
When QBI is fully phased out, the S-Corp optimization focuses entirely on payroll tax savings. Dr. Kim sets a defensible salary of $350,000 (reasonable for an orthopedic surgeon) and takes $300,000 as distributions, saving approximately $8,700 in Medicare tax alone, plus avoiding the 0.9% Additional Medicare Tax on distributions above $250K.

Decision Tree: Does QBI Apply to YOU?
A Step-by-Step Flowchart for Physician QBI Eligibility
Do you have business income from a pass-through entity (S-Corp, LLC, sole prop, partnership)?
Yes
Continue to next question
No
QBI does not apply. W-2-only physicians cannot claim QBI on employment income.
Is your total taxable income below $191,950 (single) or $383,900 (MFJ)?
Yes
Full QBI deduction available (23% of QBI). The SSTB rules do not apply below the threshold.
No
Continue to next question
Is your total taxable income above $241,950 (single) or $483,900 (MFJ)?
Yes
QBI is fully phased out on SSTB (medical) income. Consider spin-off strategy for non-medical income.
No
Continue to next question
You are in the SSTB phase-out range. Can you reduce taxable income into or below the range?
Yes
Strategies: maximize retirement contributions (Solo 401k, cash balance plan), HSA, charitable giving, cost segregation on rental properties.
No
Partial QBI available. Optimize S-Corp salary to maximize the deduction within the phase-out zone.
The most powerful QBI planning lever for high-income physicians is reducing taxable income into the phase-out range. A physician MFJ at $500,000 who contributes $72,000 to a Solo 401(k) and $30,000 to a cash balance pension plan drops to $401,000 — suddenly inside the phase-out zone with a partial QBI deduction worth thousands. Stack HSA contributions and charitable giving to push even lower.

Spin-Off Strategy for Non-Medical Income
Preserving QBI When You're Above the SSTB Ceiling
If your total taxable income puts you above the SSTB ceiling ($241,950 single / $483,900 MFJ), you get zero QBI deduction on your medical practice income. But here is the planning opportunity that many physicians miss: the SSTB classification applies to the activity, not to you as a person. If you have income from activities that are not health-care related, that income can qualify for QBI through a separate entity.
Non-Medical Income Streams That Avoid SSTB
| Income Source | SSTB? | QBI Eligible? | Recommended Entity |
|---|---|---|---|
| Medical practice revenue | Yes | Phase-out applies | S-Corp (for SE tax savings) |
| Medical device consulting | Depends on structure | Potentially | Separate LLC |
| Real estate rental income | No (unless triple-net) | Yes (if qualifies as trade/business) | Separate LLC |
| Online course sales (non-medical) | No | Yes | Separate LLC or S-Corp |
| Medical staffing company | No (if structured correctly) | Yes | Separate S-Corp or LLC |
| Product sales / e-commerce | No | Yes | Separate LLC |
| Coaching / non-medical consulting | Potentially SSTB (consulting) | Depends on classification | Separate LLC — get CPA guidance |
| Expert witness work | Yes (legal services element) | Phase-out applies | Flows through medical S-Corp |
IRS Anti-Abuse Rules for Spin-Offs
The IRS has specific anti-abuse rules under Reg. 1.199A-5(c)(2) that prevent physicians from simply relabeling medical income as non-SSTB. If the spin-off entity shares significant common ownership, common customers, or common employees with your SSTB practice, the IRS may aggregate them and treat all income as SSTB. The spin-off must be a genuinely separate business with its own operations, customers, and economic substance. We structure these carefully for clients.
Example: Spin-Off for a Surgeon with a Coaching Business
Dr. Ramirez, a general surgeon earning $550,000 from her practice, also runs a physician financial wellness coaching program generating $120,000/year. The coaching business has its own website, its own clients (not her patients), and no shared employees with the practice.
| Factor | Medical Practice | Coaching Business |
|---|---|---|
| Entity | Ramirez Surgery LLC (S-Corp) | Physician Wealth Coaching LLC |
| Annual Revenue | $550,000 | $120,000 |
| SSTB Classification | Yes (health care) | No (coaching / education) |
| QBI Available | $0 (above MFJ ceiling) | Up to $27,600 (23% x $120K) |
| Tax Savings at 37% | $0 | Up to $10,212 |
| Entity Selection | S-Corp for SE tax savings | LLC (or S-Corp if income grows) |
By operating the coaching business through a separate entity with genuine economic separation, Dr. Ramirez preserves the full QBI deduction on non-medical income. The coaching business income passes through her personal return but is not subject to the SSTB phase-out.
The spin-off strategy is particularly valuable for physicians who are building secondary income streams: medical education platforms, consulting practices, real estate businesses, or product companies. Structure them correctly from day one and you preserve QBI permanently. Restructuring after the fact is harder and can trigger anti-abuse scrutiny. See our entity structure guide for detailed setup guidance.
W-2 vs 1099 Physician Scenarios
Dollar-for-Dollar Comparison
Your QBI planning depends entirely on how you earn your physician income. Let's walk through the three most common scenarios with real numbers.
Scenario A: Pure W-2 Physician (Employed)
Dr. Lee — Hospitalist, W-2 Employee, $320,000/year
- QBI deduction: $0. W-2 income is not qualified business income.
- S-Corp election: Not applicable (employee, not business owner).
- Alternative strategies: Backdoor Roth IRA, HSA, 457(b) if available, charitable giving.
Scenario B: W-2 + 1099 Side Income
Dr. Chen — ER Physician ($280K W-2) + Locum Tenens ($90K 1099)
- Total income: $370,000. MFJ taxable income (after deductions): ~$340,000.
- Below MFJ SSTB threshold ($383,900). Full QBI on 1099 income.
- QBI deduction: 23% x $90,000 = $20,700. Tax savings at 35%: $7,245.
- S-Corp on 1099 income saves additional ~$7,500 in SE tax.
- Combined benefit: ~$13,800/year from S-Corp + QBI.
Scenario C: Full-Time 1099 / Private Practice Owner
Dr. Okafor — Locum Tenens, 100% 1099, $420,000 net income, MFJ
- S-Corp salary: $180,000. Distributions: $240,000.
- Taxable income ~$400,000 (after Solo 401k). In SSTB phase-out range.
- SSTB factor: ~83.9%. QBI = $240,000 x 23% x 83.9% = $46,313.
- QBI tax savings at 37%: $14,901.
- S-Corp SE tax savings: ~$20,880.
- Combined benefit: ~$35,781/year from optimized S-Corp + QBI.
Strategy: maximize retirement contributions to push taxable income lower in the phase-out range. Adding a cash balance plan ($30K-$100K+ contribution) could further increase the SSTB factor and QBI deduction.
The W-2 + 1099 scenario (Scenario B) is often the most tax-efficient physician structure for QBI — because the W-2 income already satisfies the Social Security wage base, and the 1099 income through an S-Corp creates both SE tax savings and QBI deduction. This is the ideal setup for moonlighting physicians. Learn more: physician tax deductions guide.
Common QBI Mistakes Physicians Make
Avoid These Costly Errors
Mistake #1: Assuming W-2 income qualifies for QBI
This is the most common misconception. Only pass-through business income qualifies. If you are employed and receive a W-2, that income is permanently excluded from Section 199A — regardless of your income level.
Mistake #2: Ignoring the SSTB classification
Some physicians (or their CPAs) claim the QBI deduction without realizing health care is an SSTB. If your taxable income is above the thresholds, this deduction is reduced or eliminated on medical income. Claiming it incorrectly triggers IRS scrutiny.
Mistake #3: Not optimizing S-Corp salary for QBI
Setting an S-Corp salary without considering the QBI impact leaves money on the table. Every dollar of salary reduces QBI. The optimal salary requires modeling both the SE tax savings and the QBI deduction simultaneously.
Mistake #4: Missing the spin-off opportunity
Physicians with non-medical income streams often run everything through a single entity. This means all income gets SSTB treatment. Separating non-medical income into a distinct entity can preserve QBI deductions worth thousands per year.
Mistake #5: Failing to reduce taxable income into the phase-out range
Many physicians just above the SSTB ceiling could access partial QBI by maximizing retirement contributions (Solo 401k, cash balance plan), HSA, or charitable giving. A $50,000 additional retirement contribution that brings you into the phase-out range can unlock $5,000-$10,000+ in QBI deductions.
Mistake #6: Not considering the W-2 wage limitation
For S-Corp owners in the phase-out range, the QBI deduction is also limited to the greater of (a) 50% of W-2 wages paid by the S-Corp, or (b) 25% of W-2 wages plus 2.5% of qualified property basis. Setting your S-Corp salary too low can inadvertently cap your QBI deduction below the 23% amount.
Mistake #7: Treating QBI as temporary (pre-OBBBA thinking)
Before the OBBBA permanently extended Section 199A, some advisors discouraged long-term QBI planning because the deduction was set to expire after 2025. That is no longer the case. QBI planning should now be a permanent part of every physician's entity structure and compensation strategy.
