If you own a medical, dental, chiropractic, or veterinary practice, you’ve probably read a lot of financial advice aimed at “business owners” — and quietly noticed that a chunk of it doesn’t seem to fit your situation. There’s a reason for that. The single most-promoted tax break for pass-through business owners, the Qualified Business Income (QBI) deduction, was written in a way that largely excludes high-earning practice owners. Most general business-owner content glosses over this. For you, it’s the whole ballgame.
This piece is for practice owners across Texas — in San Antonio, Austin, Dallas, Houston, and the communities in between — and nationwide, who are earning well, paying a lot in tax, and want to understand where the real planning leverage actually is once the headline deduction is off the table. It’s educational rather than prescriptive: the goal is to show you the mechanics clearly so you know which questions are worth asking, not to prescribe a strategy that can only be built around your specific numbers. (If you’re earlier in your career, the more foundational question is simply when to bring a planner in at all — something we’ve written about for physicians in particular.)
The SSTB Problem in Plain Terms
The QBI deduction (Internal Revenue Code Section 199A), made permanent under the One Big Beautiful Bill Act in 2025, lets many owners of pass-through businesses deduct up to 20% of their qualified business income. For a lot of business owners, that’s an enormous benefit — a fifth of business profit, deducted before tax.
Here’s the catch for practice owners. The deduction is restricted for what the tax code calls a Specified Service Trade or Business, or SSTB. And the very first category of SSTB listed in the statute is health. Medicine, dentistry, chiropractic, and veterinary care all fall squarely inside it. So do law, accounting, consulting, financial services, performing arts, and athletics — the common thread being businesses whose income depends primarily on the skill or reputation of the people providing the service. That’s a fair description of nearly every clinical practice.
For SSTB owners, the QBI deduction phases out as taxable income rises above a threshold — and unlike non-SSTB businesses, it phases out all the way to zero. There’s no wage-and-property backstop to land on. In 2026, the phaseout begins at $201,750 of taxable income for single filers and $403,500 for joint filers, and runs across a range of $75,000 (single) or $150,000 (joint) above those starting points — so the deduction is gone entirely at $276,750 (single) and $553,500 (joint). A married practice owner whose taxable income sits more than $150,000 above the joint threshold gets no QBI deduction at all.
Most successful practice owners are comfortably past that ceiling. Which means the deduction everyone talks about for business owners is, for you, often worth nothing — or a fraction of what a non-SSTB business of the same size would receive. Understanding that isn’t cause for frustration; it’s the starting point for planning that’s actually built for your situation rather than borrowed from someone else’s.
Where the Real Leverage Is
Once you accept that the marquee deduction largely doesn’t apply, the planning conversation gets more interesting, because the levers that do move meaningfully for practice owners are ones general business content rarely covers in depth.
Retirement Plan Design — The Biggest Lever You Have
This is where practice owners have an advantage most employees and even many other business owners don’t: the ability to shelter very large amounts of income through a well-designed retirement plan. And it goes far beyond maxing out a 401(k).
A solo or group 401(k) lets you defer $24,500 in 2026 as an employee (plus catch-up contributions if you’re 50 or older), and total additions to a defined contribution plan can reach $72,000 per participant. That alone is substantial. But the real power tool for a high-earning, often older practice owner is a cash balance or defined benefit plan layered on top of the 401(k).
Here’s why that layering is so powerful, mechanically. A 401(k) is a defined contribution plan: the limit is a fixed dollar amount, the same for a 40-year-old and a 60-year-old. A cash balance plan is a defined benefit plan: the law caps the future benefitit can pay (a maximum annual benefit of $290,000 in 2026), and the allowable annual contribution is whatever an actuary calculates is needed to fund that benefit by retirement. The closer you are to retirement, the fewer years there are to fund the same target — so the permitted annual contribution rises sharply with age.
The practical effect is dramatic. A practice owner in their late 30s might be limited to a cash balance contribution in the low tens of thousands. The same plan for an owner in their mid-50s can frequently absorb well into six figures annually — often in the $150,000 to $250,000-plus range, depending on the plan’s design, the owner’s compensation, and the broader employee census — entirely on top of the 401(k) and profit-sharing contributions. Stacked together, a 50-something practice owner can sometimes move $250,000 to $350,000 or more out of taxable income in a single year through plan design alone.
That’s not a rounding error against the lost QBI deduction; for many practice owners it dwarfs it. And it does so precisely because it sidesteps the SSTB problem entirely: a retirement plan contribution reduces taxable income regardless of whether your business is an SSTB. The deduction you were phased out of gets replaced by a far larger one the SSTB rules can’t touch.
The mechanics come with real obligations, which is why this is design work rather than a form you file. These plans require actuarial administration, a multi-year funding commitment (you’re expected to fund the plan consistently, not just in good years), and careful coordination with what you contribute on behalf of your staff — the plan has to satisfy nondiscrimination testing, which in a practice with several employees becomes its own design problem and a real cost to weigh. Done well, a combined 401(k) and cash balance structure is frequently the single largest tax-reduction move available to a profitable practice owner. Done carelessly, it can over-promise contributions you can’t sustain or fail testing in a way that forces unexpected staff contributions. The leverage is enormous; so is the importance of designing it around your actual numbers.
Entity Structure and Reasonable Compensation
Many practices operate as S corporations, and for good reason — the structure can reduce self-employment/payroll tax by splitting the owner’s take between W-2 salary and distributions. But it has to be done correctly. The IRS requires that an S corporation owner-employee pay themselves “reasonable compensation” for the work they actually do before taking distributions. Set the salary too low to dodge payroll tax and you’re inviting a reclassification. Set it without analysis and you may be leaving money on the table or creating risk.
There’s a second-order interaction worth knowing: because the QBI deduction (when it applies) is calculated on business income afterowner W-2 wages are subtracted, and because SSTB owners above the threshold lose the deduction anyway, the salary-versus-distribution math for a practice owner often looks different than it does for a non-SSTB business. The reasonable-compensation question for practice owners is really a payroll-tax and retirement-plan-funding question, not a QBI-optimization question. That reframing matters — and it connects directly to the section above, because the W-2 wages you run through payroll are also what your retirement plan contributions are calculated against.
The PTET SALT Workaround
The OBBBA raised the individual state-and-local-tax (SALT) deduction cap to $40,000 through 2029, with a phase-down for higher earners and a return to the $10,000 cap in 2030. But it left intact the pass-through entity tax (PTET) workaround that many states have enacted — a mechanism that lets the businesspay state income tax and deduct it at the entity level, effectively moving an otherwise-capped individual deduction onto the business return where no cap applies. Texas practice owners with no state income tax won’t use this, but practice owners earning income in states that do impose one — or those who own interests in practices across state lines — should have it on their radar. It’s one of the few SALT-related levers OBBBA preserved, and for a practice owner with meaningful state tax exposure it can be worth more than the individual cap increase itself.
Practice Transition and Exit
For most practice owners, the practice itself is the largest asset on the balance sheet — and turning it into retirement income is its own discipline. Whether the eventual path is a sale to a partner or associate, a roll-up to a larger group or DSO/dental-service or physician-practice-management organization, or a wind-down, the structure of that transition drives the tax outcome enormously. The decisions made years ahead — entity type, how the real estate is held, whether equipment was depreciated through a cost segregation study, whether the deal is structured as asset versus stock — all shape what you keep. (Where a transaction involves C-corporation stock specifically, an additional set of rules like the QSBS gain exclusion can come into play.) This is worth starting long before you intend to step away, because the most valuable moves are the ones with a multi-year runway.
A Note on the Real Estate
A large share of practice owners also own the building their practice operates in, usually through a separate entity that leases back to the practice. That’s frequently a smart structure, and it opens planning of its own: depreciation strategy on the building and improvements, the lease arrangement between the two entities, and the eventual decision of whether the real estate sells with the practice or stays behind as a continuing income stream in retirement — income that, once you’re on Medicare, also interacts with the IRMAA premium surcharges tied to your income. The building is often a second business hiding inside the first, and it deserves its own plan.
How We Think About This With Practice Owners
The throughline is that practice-owner planning is not general business-owner planning with a different logo on it. The SSTB rules change which moves matter. The biggest lever is usually retirement plan design, not the QBI deduction. The entity and compensation questions are about payroll tax and plan funding, not chasing a deduction you’ve likely already phased out of. And the practice itself is both your income engine today and your largest retirement asset tomorrow, which means the exit plan and the accumulation plan are really one plan.
None of this is one-size-fits-all — the right structure for a 58-year-old dentist with three associates and a building looks nothing like the right structure for a 41-year-old chiropractor running a solo office, and both look different again from a multi-physician group. The value is in modeling your actual numbers and sequencing the moves in the right order. But knowing where the leverage genuinely lives — and where it doesn’t — is the difference between borrowing someone else’s plan and building one that fits the practice you actually own.
Common Questions
Why doesn’t the 20% QBI deduction help most practice owners? Because medical, dental, chiropractic, and veterinary practices are Specified Service Trades or Businesses (SSTBs) under the tax code’s “health” category. For SSTB owners, the QBI deduction phases out entirely across the 2026 range of $201,750–$276,750 (single) or $403,500–$553,500 (joint). Most profitable practice owners earn past that ceiling and receive little or no deduction — unlike a non-SSTB business of the same size, which can retain a partial deduction based on W-2 wages and property.
What’s the single biggest tax-reduction move for a practice owner? For most high-earning practice owners, it’s retirement plan design — and specifically layering a cash balance or defined benefit plan on top of a 401(k). Because these contributions are actuarially calculated to fund a future benefit, they scale sharply with age: an owner in their 50s can often shelter well into six figures annually through the cash balance plan alone, on top of 401(k) and profit-sharing contributions. Critically, a retirement plan contribution reduces taxable income regardless of the SSTB rules, which is exactly why it’s so valuable when the QBI deduction isn’t available.
Should my practice be an S corporation? Often, but not automatically — and the analysis for a practice owner differs from generic business-owner advice. The S corporation structure can reduce payroll tax by splitting income between reasonable W-2 salary and distributions, but the salary has to genuinely reflect the work performed, or it invites IRS reclassification. For SSTB owners above the income threshold, the decision is driven by payroll tax and retirement-plan funding considerations rather than by QBI optimization, since the deduction is usually already phased out.
When should I start planning my practice exit? Years before you intend to leave. The structure of a practice transition — sale to an associate, roll-up to a larger group, or wind-down — drives the tax result, and the most valuable moves (entity structure, how the real estate is held, depreciation strategy, asset-versus-stock deal structure) need a multi-year runway to execute well. Starting early turns the practice from an asset you hope to sell into a planned source of retirement income.
I own the building my practice is in. Does that change anything? Yes — it’s often a second business hiding inside the first. Holding the real estate in a separate entity that leases to the practice opens its own planning around depreciation strategy, the lease structure between the entities, and whether the building sells with the practice or stays behind as continuing retirement income. It deserves its own plan rather than being treated as an afterthought to the practice.
