Associate pay is a cost of buying clinical capacity. Owner pay is a return on owning the business. Put them on the same line and you cannot read either one.
Two dentists produce in your practice. One of them owns it. Their compensation looks similar on a bank statement and behaves nothing alike in your financials, and the difference is not a technicality. It determines whether the profit number at the bottom of your P&L means anything at all.
Here is how a CFO reads it. Associate pay is the price of clinical capacity you bought. Owner pay is partly a wage for clinical work you performed and partly a return on the business you own, and those two halves answer different questions. Get the split wrong and you either overpay tax or invite the IRS to redo the arithmetic for you.
If your practice is an S-Corp, you cannot take everything as distributions. The IRS position is unambiguous: S corporations must pay reasonable compensation to a shareholder-employee for services provided before non-wage distributions may be made, and it will reclassify distributions as wages if you do not.
The IRS suggests starting the analysis by asking what generated the practice's gross receipts: the shareholder's personal services, non-shareholder employees' services, or capital and equipment. Receipts traceable to the shareholder's own services should be treated as wages. Sit with that for a moment as an owner-operator. In a solo or small practice, most production traces to your hands. That framing does not favor an aggressive salary.
The IRS publishes the factors it weighs, and they are workable rather than mysterious. They sort into three groups. What you bring: training and experience, duties and responsibilities, and the time and effort you actually devote to the business. What the market says: what comparable businesses pay for similar services, plus any compensation agreement or formula you used to set the number. What the company's own history shows: its dividend history, what it pays non-shareholder employees, and the timing and manner of bonuses to key people.
Read together, those factors describe a valuation of your services. They are not a share of your profits, and that distinction matters more than it sounds like it should.
The case law is not theoretical, and one of them is a clinician. In Veterinary Surgical Consultants, P.C. v. Commissioner, 117 T.C. 141 (2001), a veterinarian was the sole shareholder and only full-time worker, performing all the services that generated the corporation's income roughly 33 hours a week. The corporation reported no wages and called the payments his share of net income: about $84,000, $173,000 and $161,000 across three years. The Tax Court held all of it was subject to employment taxes, on the rule that an officer who performs substantial services and receives remuneration in any form is an employee.
The better known case is David E. Watson, P.C. v. United States, 668 F.3d 1008 (8th Cir. 2012). A CPA paid himself $24,000 a year while taking roughly $190,000 a year in distributions. The court recharacterized $91,044 a year as wages and the Eighth Circuit affirmed. And in Joseph Radtke, S.C. v. United States, 895 F.2d 1196 (7th Cir. 1990), an attorney took a $0 salary and $18,225 in dividends, and the entire amount was held to be wages.
Two things to take from those, and one thing not to. Take that a zero or nominal salary is the fact pattern that loses, and that courts look at substance over the label on the payment. Do not take the $91,044 as a benchmark. It was one expert's valuation of one CPA's services in 2002 and 2003, not a floor and not a standard.
You should also know what is not a rule. The 60/40 split, the 50/50 split, and the one-third salary convention appear in no IRS guidance, no regulation and no court opinion. They are rules of thumb that circulated among practitioners and hardened into folklore by repetition. They survive because they are easy to apply and because most returns are never examined, which is a very different thing from being defensible.
The structural problem is that a ratio answers the wrong question. Reasonable compensation asks what your services were worth. A percentage of what you pulled out of the practice says nothing about that. Two owners can distribute identical cash from practices with completely different clinical loads, and the same 60/40 split would be generous for one of them and indefensible for the other. The ratio also moves with profitability instead of with your work, so a strong year quietly raises your "reasonable" salary and a slow year lowers it, while the clinical days you actually worked barely changed. That is backwards from how the standard reads, and it is the part an examiner will notice.
So set the number from the work, and treat whatever ratio falls out of it as a result rather than an input. Here is how to build it.
Distributions avoid payroll tax. Salary does not. The self-employment and FICA burden is 15.3%, made of 12.4% for Social Security and 2.9% for Medicare.
But the Social Security half stops. For 2026 the wage base is $184,500, per the Social Security Administration. Above that, an additional dollar of salary carries 2.9% for Medicare, plus the 0.9% Additional Medicare Tax above $200,000 single or $250,000 married filing jointly, thresholds that are not indexed for inflation.
So the salary decision is worth real money in the band below $184,500 and much less above it. An owner arguing about whether reasonable salary is $190,000 or $220,000 is arguing over the 2.9% band. An owner arguing about whether it is $60,000 or $150,000 is arguing over the 15.3% band, which is where the money and the risk both live.
There is a second, quieter cost to setting salary too high. Amounts received as reasonable compensation from an S corporation do not count as qualified business income, so every dollar moved from distribution to salary is a dollar removed from the QBI base. How much that matters depends on your taxable income and is a question for your tax preparer, but it means the high side is not free.
What the high side is not is a compliance risk. There is no IRS penalty for overpaying yourself in an S-Corp, because overpaying raises federal revenue. Excessive compensation is a C-corporation deduction doctrine and it does not apply here. Too low is a compliance problem. Too high is just waste.
Since there is no published dental figure and no safe harbor, build it rather than borrow it. Ask what you would have to pay an associate to cover your clinical days, then add a management wage for the administrative work you actually do. That is a defensible construction directly aligned with the IRS factors on comparable pay and duties.
The associate half of that has published anchors. Writing in Dental Economics, Allen M. Schiff, CPA, a founding member of the Academy of Dental CPAs, describes general-dentist associate pay at roughly 35% of collections or around 25% of net production, with fixed bases in the $125,000 to $150,000 range. Those are the professional judgment of dental CPAs rather than survey data, so use them as a starting point you can explain, not as a benchmark you can cite as authority. For scale, the ADA Health Policy Institute puts average income for general practice dentists at $215,320 in 2025.
Write the method down when you set the number. A file note explaining how you arrived at your salary, with the comparable associate rate and the management component, is worth considerably more in an examination than a number with no reasoning behind it.
Associates are generally paid one of three ways. A daily or annual guarantee, which is predictable for the associate and puts the production risk on you. A straight percentage of production or collections, which does the reverse. Or a hybrid, typically a guarantee with a true-up once collections pass a threshold, which is how most practices actually handle the first year while an associate builds a schedule and works through insurance credentialing.
The percentage matters less than what it multiplies. At 35% of collections the associate shares the risk that money never arrives. At roughly 25% of net production you absorb that risk entirely, and the lower rate is the price of absorbing it. They are not two levels of generosity. They are two risk allocations, and an agreement that says "production" without specifying which production number the percentage runs on has left the most expensive word in the contract undefined.
This is the part that changes what your financials tell you.
Associate compensation is a clinical cost. It does not belong in your staff payroll line. Schiff is explicit about this in his overhead framework: within the employee cost section of your P&L, do not include the cost of your associate. That framework holds employee costs excluding associates to no more than 28% of collections with a goal of 24% to 26%, and puts doctor compensation, owner and associates together, at 35% to 40%. Bury an associate inside staff payroll and your staffing percentage will read as a crisis that does not exist.
Owner salary is a payroll expense. Owner distributions are not an expense at all. A distribution is a balance sheet event. It reduces your stock basis dollar for dollar and is reported in Box 16D of your K-1, not as a deduction against income. Nothing about taking money out of your practice is a cost of running it.
That single fact produces the most common misreading in dental financials. Consider the same practice, same cash to the same dentist, two ways of taking it. Take everything as distributions and no owner compensation hits the P&L at all, so reported profit is inflated by the full value of your clinical and management labor. Take everything as salary and profit collapses toward zero. Same practice, opposite-looking statements, and every benchmark comparison, valuation multiple and lender cash-flow read is wrong in whichever direction you chose.
Which is why you normalize. Before reading profitability, restate owner compensation to a market rate for the work actually performed. What is left is the return on the business rather than pay for labor, and that residual is the number a buyer, a lender or you should be looking at. The useful part is that the normalization you do for management reporting and the reasonable compensation analysis the IRS wants are the same exercise run for two different audiences, so it is work you only have to do once.

None of the above applies if you are not an S-Corp, so it is worth knowing which conversation you are in. Full detail sits in our guide to S-Corp versus LLC for dental practices, but the short version:
A sole proprietor or single-member LLC is a disregarded entity reporting on Schedule C. There is no salary and no distribution, only a draw, and all net income is exposed to self-employment tax. A partnership files Form 1065 as an information return and issues K-1s; partners are not employees and should not be issued a W-2. An S-Corp files Form 1120-S, runs real payroll with quarterly 941s and an annual 940, makes federal tax deposits, and filed a Form 2553 to get there.
That last list is the cost floor of the election, and it is a real one. Whether the payroll tax saved exceeds the cost of an extra return, a payroll service and the administration is arithmetic on your specific numbers, not a threshold you can read off a blog. Anyone quoting you a universal income level where the S-Corp "makes sense" is handing you a convention, and the only version of that number worth having is the one run on your own practice.
P.S. Reciprocity Accounting keeps owner salary, owner distributions and associate compensation in three separate accounts, so your profit line measures the practice instead of measuring how you chose to pay yourself. See how we can help your practice.
There is no published dental figure and no IRS safe harbor. Build it instead: what you would pay an associate to cover your clinical days, plus a management wage for the administrative work you actually perform. That construction maps directly onto the IRS factors on comparable compensation and duties, and writing down how you got there is worth more than the number itself if you are ever asked.
No. Neither is 50/50 or the one-third convention. None of them appear in IRS guidance. The standard is reasonable compensation for services actually performed, judged on the listed factors, and a ratio does not satisfy it.
It can be wasteful, but it is not a compliance risk. There is no penalty for overpaying yourself in an S-Corp. The cost is the payroll tax you did not need to pay on dollars below the Social Security wage base, plus the reduction to your qualified business income, since reasonable compensation from an S corporation is excluded from QBI.
No. A distribution is a balance sheet event that reduces your stock basis and is reported in Box 16D of your K-1. It is not a deduction against income. If distributions are showing up as an expense in your financials, your profit number is wrong and so is anything built on it.
No. Associate compensation is a clinical capacity cost and belongs with doctor compensation, separate from team payroll. Dental CPA overhead frameworks hold staff costs to roughly 24% to 26% of collections with associates excluded. Including an associate in that line will make a healthy practice look badly overstaffed.
Most often because you are taking compensation as distributions rather than salary, so the value of your own clinical and management labor never appears as a cost. Restate owner compensation to a market rate for the work you actually do, and the profit that remains is the return on the business. That is the number worth tracking month over month.
