Every successful medical or dental partnership eventually faces the same two questions: how does an associate become an owner, and how does an owner become a former owner? The answers get written into a partnership or shareholder agreement, and the exact formulas chosen determine whether the transition is a mostly administrative exercise or a several-year source of resentment.

For a small-group practice in Idaho or Utah adding its first partner, or a mature group updating a decade-old agreement, the mechanics matter. This piece covers what a buy-in is really buying, the three formulas most practices actually use, how associates fund the purchase without leveraging their houses, the tax treatment on both sides of the table, and the buy-out language every partnership should have in place before it is needed.

What the Buy-In Is Really Buying (Equity vs Income Stream)

A buy-in purchases two different things at once, and clarity about the split is where most partnership disputes start.

The first is equity: a share of the practice’s tangible assets (equipment, receivables, real estate if included), less liabilities. Equity is what shows up on the balance sheet and what the new partner would receive if the practice were dissolved tomorrow.

The second is the income stream: a share of future distributable earnings. That is the goodwill, the ongoing patient base, the referral relationships, and the operating platform the founders built. In most medical and dental practices, the income stream is where the real value lives, and it is usually the larger portion of a buy-in.

The Three Common Buy-In Formulas

Practices use three main formulas, sometimes in combination:

• AR-based (or hard asset only): The associate buys a share of net tangible assets, typically working capital including accounts receivable, less current liabilities. Goodwill is not paid for. The associate essentially earns into partnership through future practice building.
• Book value: The associate buys a share of the practice’s book equity as stated on the balance sheet. Simple to compute; often understates real value if the practice has significant goodwill.
• Appraised value: The associate buys a share of the practice’s appraised fair market value, including goodwill. Most accurate; most expensive to the incoming partner and most defensible to the outgoing partner.

Founder practices sometimes use a hybrid: appraised value for goodwill, book value for hard assets, and an installment structure for both. The choice is a negotiation between “the associate should pay for what they are getting” and “we want them to become a partner while they can still afford it.”

How Associates Fund a Buy-In Without a Second Mortgage

Very few associate physicians or dentists have $200,000 to $500,000 in cash to write a check for a buy-in. Three funding structures work in practice:

Practice-financed buy-ins are the most common. The practice sells the interest to the associate over three to seven years, with the associate paying through a reduction in take-home compensation. The math has to work for both sides: the associate has to end up with meaningfully higher long-term earnings; the seller has to receive a market-rate payment for the interest.

Bank-financed buy-ins use practice or physician loans. Several regional and specialty lenders will finance a partner buy-in when the practice’s cash flow supports it. Rates and terms have moved considerably in the last three years; the current lending market matters.

Deferred compensation buy-ins let the associate earn into partnership through reduced comp over time without a formal debt. The IRS treats these carefully, and structure matters to avoid unintended tax consequences.

Tax Treatment on Both Sides of the Table

Tax treatment differs meaningfully between the buyer and the seller, and it depends on entity type.

For an S corporation practice, a stock sale to the associate is generally capital gain to the seller and non-deductible to the buyer, who acquires stock with a carryover basis. For a partnership or LLC, an interest sale can create ordinary income on hot assets (receivables, depreciation recapture) mixed with capital gain, with the buyer receiving an inside basis step-up under §754 if the practice makes the election.

The choice of entity, the choice of §754 election, and the structure of the sale together determine whether the associate is buying with pre-tax or after-tax dollars, and whether the seller is receiving ordinary or capital gain. Running the tax math before the deal is documented is essential.

The Buy-Out Formula Every Partnership Needs Before Day One

Every partnership agreement should specify the buy-out formula for four events: retirement, death, disability, and involuntary departure. The formula should use the same valuation approach as the buy-in (fairness on both ends of the same road), specify a payment timeline that does not bankrupt the practice, and address funding through life and disability insurance where appropriate.

The single most common cause of partnership disputes is not having this formula written down before it is needed. Once a retirement or disability event triggers the conversation, negotiating leverage sits with whoever’s interest the practice is trying to protect.

The compensation model inside a medical group is not just a payroll question. It is the group’s operating system. It shapes which physicians want to work harder, which want to leave, and which partner disputes eventually surface. Most disputes inside physician groups trace back, one way or another, to whether the compensation model still fits how the group actually operates.

Three models dominate small and mid-sized physician groups in Idaho and Utah: eat-what-you-treat, equal share, and hybrid base-plus-production. Each one works well in specific conditions and creates specific tensions when conditions change. This piece walks through how each model actually works, when each stops working, how to allocate overhead fairly, and how to transition between models without a partner revolt.

How Eat-What-You-Treat Actually Works

Eat-what-you-treat (EWYT) ties each physician’s take-home directly to what they personally produce. Each physician’s share of collections is tracked separately. Overhead is allocated to each physician (usually a mix of equal shares and pro-rata shares tied to production). The physician’s net comp is their collections minus their allocated overhead.

EWYT rewards production and clarifies economic outcomes. Partners who produce more take home more, without much internal argument about who is pulling their weight.

The tensions show up in three places. Ancillary revenue (imaging, in-office lab, physical therapy) does not map cleanly to any individual physician and requires an allocation formula. Overhead allocation is more art than science, and the split between fixed and variable overhead becomes a source of dispute. And physicians in slower building years or slower quarters bear more downside risk than in other models.

The Case for Equal Share (and When It Breaks)

Equal share treats every partner physician as equal in the compensation pool, regardless of what each one produces in a given period. All practice profits (after expenses) are divided equally among partners.

Equal share works well when the partners have similar production, similar patient panels, and similar work styles. It preserves collegiality: no partner is comparing pay stubs. It also works well in environments where production is genuinely constrained by scheduling and referral flow rather than physician effort.

Equal share breaks when production diverges materially. A partner producing 12,000 wRVUs a year subsidizing a partner producing 7,500 wRVUs eventually notices. The subsidy may be justified (mentorship, admin work, transition planning) or unjustified. Either way, equal-share groups routinely need a mechanism to have that conversation productively, or the subsidy becomes silent resentment.

Hybrid Models: Base Plus Production

The hybrid model splits comp into two components: a base guaranteed salary and a production-based upside. The base cushions slow periods and provides income stability. The production component rewards effort and volume.

The split between base and production is the key variable. A 70/30 base-heavy split (70% base, 30% production) skews toward collegiality and stability. A 30/70 split skews toward EWYT-like dynamics. Most groups sit somewhere in between and evolve the split over time.

Hybrid works well for groups adding a new partner, transitioning from equal share, or trying to balance production incentive with team culture. It is the most common model for physician-owned groups over five partners because it accommodates the most different partner situations.

How to Allocate Overhead Fairly

Overhead allocation is where compensation math either builds trust or destroys it. Three common approaches:

• Equal share of all overhead. Simple, defensible for administrative and occupancy costs. Feels unfair when one partner uses far more of a specific expensive resource
• Pro-rata to production. Each partner’s overhead allocation matches their share of production. Aligns incentives; can be complex to administer
• Hybrid allocation. Fixed overhead (rent, admin, EHR) split equally; variable overhead (medical supplies, lab, per-encounter costs) allocated by production or usage

The hybrid allocation approach is the most defensible for most groups. It reflects the reality that some costs do not scale with production and some do.

How to Transition Between Models Without a Partner Revolt

Groups transitioning from one comp model to another (usually equal share to hybrid, or hybrid to EWYT) often break the transition because they try to move too fast. Three principles help transitions work:

Model the transition first. Every partner should see, on paper, what their comp would have been under the new model for the last 12 to 24 months. Surprises after implementation kill the transition. Surprises modeled before implementation invite productive discussion.

Phase the transition over two to three years. A sudden switch from equal share to EWYT will produce a partner revolt among any partners whose comp would drop. A phased transition (25% new model, 75% old model in year one; 50/50 in year two; full new model in year three) gives partners time to adjust production, retire, or leave on their own timeline.

Preserve one anchor of stability. Even a full-production model should preserve either a modest base or a minimum guaranteed distribution. This protects the group during a bad quarter and reduces the fear that drives most opposition to a comp model change.

A solo physician earning $400,000 in a joint return can claim the full 20 percent qualified business income deduction and shave tens of thousands off the federal bill. The same physician earning $560,000 loses the deduction entirely. The rule that draws that line, IRC §199A and its specified service trade or business classification, is unforgiving for medicine. Understanding where a practice sits in the phase-in range, and how to move that position with lawful planning, is the QBI deduction physicians most often mishandle.

The good news is that the deduction survived through 2026 and is now permanent under the One Big Beautiful Bill Act. That removes the sunset uncertainty many practice owners had been planning around. What remains is the SSTB haircut, the income thresholds, and a handful of moves inside the phase-in range that can preserve some or all of the deduction.

How §199A Works for a Physician-Owned Practice

Section 199A allows owners of pass-through businesses, meaning sole proprietors, partnerships, S corporations, and LLCs taxed as either, to deduct up to 20 percent of qualified business income from taxable income. The deduction reduces the tax bill without reducing self-employment tax, and it applies at the individual level, not the entity level. For a physician-owner of a professional S corporation earning $300,000 of qualified business income after reasonable compensation, the deduction is worth up to $60,000, which at a 32 percent marginal bracket is roughly $19,200 of federal tax saved.

The catch, for medicine specifically, is the SSTB rule.

The SSTB Rule and Why Medicine Falls Under It

Section 199A explicitly names health as a specified service trade or business. So do law, accounting, consulting, performing arts, actuarial science, athletics, financial services, and any trade or business where the principal asset is the reputation or skill of the owners. For these categories, the deduction phases out based on taxable income and is fully lost above the top of the phase-in range.

For a medical or dental practice, the SSTB classification means the deduction is available at lower income levels, restricted in the phase-in range, and unavailable above it. The wage and property tests that expand the deduction for non-SSTB businesses do not open the door for a physician-owned practice above the phase-out ceiling.

2026 Income Thresholds and the Phase-In Range

For tax year 2026, the taxable income thresholds are $201,775 for single filers and $403,500 for married filing jointly. The phase-in range extends $50,000 above threshold for single filers, ending at $276,775, and $100,000 above threshold for joint filers, ending at $553,500.

Below the threshold, a physician-owner gets the full 20 percent deduction. Inside the phase-in range the deduction is proportionally reduced. Above the top of the range, an SSTB physician gets zero. A joint-filer physician with $478,500 of taxable income, exactly halfway through the phase-in range, is entitled to half the deduction.

Note that the trigger is taxable income, not qualified business income and not adjusted gross income. Retirement contributions, itemized or standard deductions, above-the-line deductions, and even the QBI deduction itself all affect the calculation.

Planning Moves Inside the Phase-In Range

Once a practice owner lands inside the phase-in range, three levers can meaningfully move the number.

Retirement contributions are the largest. A cash-balance defined benefit plan can shift six figures of taxable income into deferred territory, moving a joint-filer physician from the middle of the phase-in range to below the threshold and restoring the full deduction. For a solo physician with the capacity, this is often the single highest-leverage move available.

Reasonable compensation is the second lever, but the direction is counterintuitive. For an S corporation, higher W-2 compensation reduces qualified business income and therefore the deduction, but also reduces the SSTB owner’s taxable income by shifting profit to wages that are then reduced by employer payroll tax and 401(k) deferrals. The right level depends on facts specific to each practice.

Entity choice is the third. Splitting a practice into an SSTB entity and a non-SSTB entity, such as a real estate holding company that owns the office building, can preserve deduction on the non-SSTB side even when the medical entity is above the ceiling. The crack-and-pack strategy has become harder in recent years, and the regulations restrict shared ownership above 80 percent, so this needs careful structuring rather than a template.

The Bottom Line for Idaho and Utah Practice Owners

The §199A deduction is now permanent, which means planning around it is worth the effort every year, not just in TCJA sunset scenarios. For a physician-owner in Idaho Falls, Boise, Provo, or Salt Lake City, the value of getting the calculation right is often $10,000 to $30,000 a year, and the planning window closes on December 31.

Our team at Cooper Norman helps physician and dental practice owners in Idaho and Utah run the numbers on §199A planning alongside retirement contributions, S-corp wage decisions, and entity structure. If your taxable income for 2026 is trending toward the phase-in range, the time to model it is now, while there is still runway to move the levers.

This overview is general information, not tax advice for your specific situation.

A medical practice can be fully booked and still leave money on the table. The revenue cycle, from patient registration to final payment, is where profitability lives or dies, and most practice owners look at a fraction of the metrics that would tell them what is happening. A monthly review of the right five KPIs takes about fifteen minutes and catches most problems before they compound.

The list below is not exhaustive. It is the five KPIs a physician-owner in Idaho Falls, Twin Falls, or Provo can actually watch each month, understand quickly, and act on. Each one measures a different point in the cycle, and each has a specific fix when the number goes the wrong direction.

Clean Claim Rate: The First Signal of Front-End Health

The clean claim rate is the percentage of claims that pass the payer’s edits on the first submission, without rejection or manual rework. It is a direct reflection of front-office work: eligibility verification, correct patient demographics, current insurance, valid authorizations, and clean coding.

When the clean claim rate slips, the cause is almost always upstream of billing. Rework is expensive, and every rework claim slides into the aging bucket. Practices that push their clean claim rate up by fixing registration workflow generally see downstream metrics improve at the same time, because the same errors that cause claim rejection also cause denials.

Denial Rate: What Percentage Comes Back the First Time

Denial rate is the percentage of submitted claims returned unpaid, broken out by reason. Watching the aggregate denial rate is useful; watching it by reason code is where the money is. A rising denial rate driven by prior authorization is a very different problem than a rising rate driven by medical necessity.

The three questions a denial report should answer each month are: which payer is driving the increase, which reason code is behind it, and what is the working queue age on the affected claims. If any denial is sitting past sixty days without action, the practice is training its billers that denials do not need to be worked promptly, and that habit is hard to break once it sets in.

Net Collection Rate: The Number That Actually Pays the Bills

Net collection rate is total collections divided by allowed amount (charges after contractual adjustments). It measures how much of the money the practice is actually owed under its contracts is being collected. A net collection rate under 95% means real money is being written off, appealed poorly, or missed at the patient-responsibility stage.

The gap between 95% and 100% is the collectible money the practice is losing. On a practice with $2 million in net collections, that gap can be six figures a year. Practices rarely fix this by working harder on the same workflow; the improvement usually comes from a specific change to patient-responsibility collection at time of service, or a change to how denials over 45 days are triaged.

AR Aging: Where Your Money Is Stuck

AR aging shows the practice’s receivables broken into buckets: current, 31 to 60 days, 61 to 90 days, 91 to 120 days, and over 120 days. The number to watch is the percentage of AR sitting past 90 days. Anything over 15% in that bucket is a warning sign; over 25% is a problem that will not fix itself.

Aging concentrates the practice’s worst work. Old AR is old because someone did not follow up, a denial did not get resolved, or a patient balance was not pursued. A monthly aging review with an owner for each account over 90 days closes more claims than any process change.

Cost to Collect: The Metric Almost No One Runs

Cost to collect is total revenue cycle expense (billing staff, clearinghouse fees, outsourced billing, software) divided by net collections. It answers a question few practice owners ask: how much of every dollar we collect goes to the collecting itself?

Industry ranges vary by practice size and specialty, and the number matters less than the trend. A cost to collect that rises quarter over quarter while collections stay flat means the revenue cycle is getting more expensive to run without producing more cash. That is the moment to look hard at whether the current workflow, headcount, or vendor mix is still right for the practice.

These five KPIs are not the only metrics worth watching, but they are the ones that separate a busy practice from a profitable one. Cooper Norman’s healthcare accounting team builds monthly revenue cycle dashboards for practices across Idaho and Utah, and connects the metrics to the cash-flow forecast and owner-comp math.

The Section 41 research credit is not just for pharmaceutical companies and semiconductor plants. A dental lab designing custom prosthetics, an oral surgery practice refining a novel implant workflow, or a group practice developing a custom EHR integration can all qualify for the R&D tax credit medical practice owners often assume is out of reach. The four-part test in the tax code does not mention lab coats or clean rooms. It rewards technical work aimed at eliminating uncertainty, and clinical practices produce that kind of work more often than they realize.

The credit became more valuable in 2025. Under the One Big Beautiful Bill Act, immediate deductibility of domestic research expenses was restored, reversing the five-year amortization that had made §174 a headache since 2022. For medical and dental practices with even modest R&D activity, the combined effect of the credit plus immediate deduction is meaningful.

The Four-Part Test in Plain Language

Section 41 defines qualified research using four requirements. All four must be met.

First, the activity must have a permitted purpose, meaning it aims to develop or improve a product, process, technique, formula, invention, or software used in the taxpayer’s business. In a clinical setting, that includes a new diagnostic protocol, a modified surgical technique, or software that connects two clinical systems.

Second, the activity must be technological in nature. It has to rely on principles from the physical, biological, engineering, or computer sciences. Medicine and dentistry are biological and physical sciences, so most clinical technical work satisfies this element.

Third, the activity must aim to eliminate technical uncertainty. The physician or the lab must not know at the outset whether the approach will work or which of several approaches is best. Uncertainty is the core of the credit and the element most often missing on the practice side.

Fourth, the activity must proceed through a process of experimentation. That means evaluating alternatives, testing hypotheses, and iterating based on results. It does not have to look like a formal clinical trial.

What Actually Qualifies Inside a Medical or Dental Practice

The credit is broader than most practice owners assume. Qualifying activities in the clinical world commonly include:

• Custom prosthetic and orthotic design in a dental or oral surgery lab, where each case involves iterative fit and function work.
• Development or substantial modification of surgical instruments, guides, or splints.
• Novel treatment protocols that combine existing modalities in new ways, provided the outcome is uncertain and the process is documented.
• Custom software development, including EHR integrations, patient portals, and analytics tools built in-house.
• Process improvements in imaging or lab workflows that use technical principles and aim to improve accuracy, speed, or safety.

Activities that generally do not qualify include routine patient care, ordinary quality improvement, market research, and adopting a vendor’s product as delivered without technical modification.

§174 Under OBBBA: Immediate Deduction Restored

From 2022 through 2024, §174 required domestic research expenses to be amortized over five years rather than deducted currently. That rule reduced the effective benefit of a research effort in the year the work happened and pushed some practices to stop counting R&D activity entirely.

The One Big Beautiful Bill Act reversed that treatment. Domestic research expenses paid or incurred in tax years beginning after December 31, 2024 are immediately deductible again. Foreign research expenses remain on a 15-year amortization schedule. Retroactive relief is also available for domestic R&D investments made between 2022 and 2024, which means some practices can accelerate or amortize those prior-year costs on an amended return or under an elective method.

The interaction with the §41 credit is favorable. Immediate deduction plus the credit means the after-tax cost of qualifying research is meaningfully lower than it was through 2024.

The Payroll Offset for Newer Practices

Practices with less than $5 million in gross receipts and no gross receipts before the past five years can elect to apply up to $500,000 of the research credit against payroll tax rather than income tax. The payroll offset was doubled from $250,000 to $500,000 under the Inflation Reduction Act, and it is the most useful feature of the credit for a young practice that is not yet profitable.

A new dental practice that spent $200,000 on qualifying research activity in its second year of operations could generate a credit in the tens of thousands and apply it against the employer portion of payroll tax on the next several quarterly filings, effectively getting cash back before the practice ever owes federal income tax.

Documentation You Need Before You Claim

The credit requires contemporaneous evidence. That means dated project notes, iteration logs, cost tracking by project, employee time allocated by activity, and a written statement of the technical uncertainty being addressed. Practices that treat R&D activities as ad hoc and undocumented tend to fail on examination even when the work would have qualified.

Cooper Norman advises medical and dental practice owners in Idaho and Utah on practice tax planning, and we have credited the same activities on the manufacturing and construction side for years, including in our earlier post on the R&D credit for construction businesses. If your practice runs a dental lab, develops software in-house, or works on protocols where the outcome is not known in advance, the credit is worth a serious look.
