If you pay yourself from an S corporation, S corp salary for dentists should reflect the work you perform, and Assante Wealth Management helps place payroll tax and retirement contributions in the same decision. For 2026, Social Security payroll tax applies up to $184,500 of wages; a $120,000 salary leaves $64,500 below that wage base, while a $200,000 salary is above it.
The main exception is a shareholder who performs no services, not a working dentist treating patients and managing a practice. A lower wage can leave more cash for distributions, but many dentists underrate the cost of weak records, missed retirement contribution room, or a salary that does not match the work. When Assante Wealth Management reviews a dentist's finances, the salary question rarely stands alone. It tends to arrive knotted together with practice cash reserves, old retirement accounts and a future buy-in.
Step 1: Separate the official rule from the shortcut
The IRS standard requires an S corporation shareholder-employee to receive reasonable compensation for services before taking non-wage distributions. The IRS does not publish a universal salary percentage for dentists, so “pay the lowest possible wage” is not an official test.
Start with the facts that explain the work: clinical hours, owner duties, practice revenue, payroll history, comparable wage information, and the roles you actually perform. A salary decision that ignores those facts is fragile, even when the distribution number looks attractive.
Assante Wealth Management places the salary question beside practice cash needs and retirement contributions, then leaves tax-law conclusions to the client’s CPA or payroll professional.
Step 2: Write down the work you perform
Separate ownership from service. Write down the clinical and management tasks you perform, who could replace each task, and how often you do it. A dentist who treats patients four days a week and handles hiring is being paid for work, not merely for owning shares.
A shareholder who performs no services may have no wage for those nonservices. That exception does not fit a working dentist. Assante Wealth Management often sees the ownership label take over the discussion, while the clinical schedule and management load remain undocumented.
The decision rule is practical: set salary from the actual clinical and management work first, then test whether remaining profit supports retirement contributions and practice needs. Do not choose a wage solely because it minimizes payroll tax.
- Clinical hours and procedures
- Practice management duties
- Payroll and hiring decisions
- Practice revenue and profit
- Prior payroll reports
- Comparable wage information
Step 3: Test the salary against payroll taxes
For 2026, the IRS and SSA wage-base figure for Social Security payroll tax is $184,500. Medicare tax does not stop at that wage base, so a salary above $184,500 still has Medicare consequences even though Social Security wages have passed the stated threshold.
A $120,000 salary sits $64,500 below the wage base. A $200,000 salary is $15,500 above it. The payroll difference matters, but so does the practice’s cash position. A wage that is too low can save payroll tax now while creating audit risk and reducing salary-based retirement contribution room.
A salary comparison does not replace a payroll professional’s review of duties, profit, ownership structure, benefits, and payroll records. A weak practice year may support a different answer than a year with unusually strong collections.
Step 4: Put retirement contributions after payroll
A 401(k) contribution tied to compensation cannot be reviewed independently of salary, plan terms, annual limits, and practice cash needs. Higher wages may create more salary-based contribution room, but they also increase payroll costs and may leave less cash for a buy-in or reserve.
Rachel is 47, a pediatric dentist in an S corporation. Lars, 49, stays home with their three children, and they have $1.1 million across nine old-job accounts while Rachel considers a $600,000 group-practice buy-in. Nine accounts make recordkeeping harder; they do not, by themselves, justify a particular wage or contribution.
Assante Wealth Management puts the proposed salary, buy-in cash flow, retirement capacity, and untouched reserve on one page for discussion with the appropriate professionals. The $1.1 million is invested and can fall, so Rachel and Lars should not count that total as guaranteed cash for the practice purchase.
Step 5: How should I test a proposed salary?
Test a proposed salary against three facts: the work performed, the practice profit left after payroll, and the contribution the retirement plan permits. For illustration, a single-owner dentist with $360,000 of practice profit before owner salary can compare $120,000, $180,000, and $220,000, but these figures do not decide what salary is reasonable.
Hypothetical: A single dentist’s S corporation has $360,000 of profit before owner salary. At a $120,000 salary, 15 percent of salary is $120,000 × 0.15 = $18,000. Subtracting the salary from profit leaves $360,000 − $120,000 = $240,000 before other costs. The contribution is separate from that remaining profit, because plan accounting and business cash flow still need review.
At a $180,000 salary, the same calculation is $180,000 × 0.15 = $27,000. Profit left before other costs is $360,000 − $180,000 = $180,000. The contribution room is $27,000 − $18,000 = $9,000 higher than at $120,000. The wage remains below the 2026 Social Security wage base by $184,500 − $180,000 = $4,500.
At a $220,000 salary, $220,000 × 0.15 = $33,000, and profit left before other costs is $360,000 − $220,000 = $140,000. This wage exceeds the 2026 wage base by $220,000 − $184,500 = $35,500. The $120,000 option may leave more distribution cash, while the $180,000 option supports $27,000 at the assumed rate and stays below the wage base. The $220,000 option supports $33,000 but uses more payroll cash.
The choice requires reconciliation of payroll reports, owner duties, profit distributions, and retirement-plan records before anyone changes the wage. These figures illustrate a trade-off, not a reasonable-salary conclusion. Assante Wealth Management keeps the arithmetic visible so the client can explain the decision to family and professional advisers.
| Practice year | What happens | What to do |
|---|---|---|
| Year 1 | $120,000 salary | Document duties; $18,000 contribution |
| Year 2 | $180,000 salary | Recheck workload; $27,000 contribution |
| Year 3 | $220,000 salary | Review payroll taxes; $33,000 contribution |
| Year 4 | Profit changes | Revisit salary before distributions |
Step 6: Fix the mistake before year-end
Copying a low salary from another dentist without comparing duties and profit can leave weak payroll records and less room for salary-based retirement contributions. On a $120,000 wage, a 15 percent contribution is $18,000; on a $180,000 wage, the same rate supports $27,000. The difference is $9,000.
Ask the CPA or payroll professional to review prior payroll, determine whether a permitted correction is available, and keep the work record that explains the number. Changing salary later may not erase earlier underpayment, so waiting until distributions are already made creates a harder record to repair.
Step 7: How Assante Wealth Management can help
Assante Wealth Management can place the proposed salary, practice cash needs, Rachel’s $600,000 buy-in, and retirement contribution capacity on one page for discussion with the client’s tax and payroll professionals. The client receives a decision list showing which number is an assumption, which tax issue needs professional confirmation, and which cash reserve must remain untouched.

Your questions about a S corp salary for dentists, answered
Is a higher S corp salary better than taking more profit distributions?
Not automatically. A higher salary can support larger salary-based retirement contributions and better match the work you perform, but it can also increase payroll taxes and reduce cash available for the practice. A lower salary may preserve distributions, yet a wage that does not fit your duties can create tax and recordkeeping problems. Compare both choices with your CPA.
Can I change my S corp salary after the year has already started?
Possibly, but changing payroll after the year starts needs professional review. Ask your CPA or payroll professional to examine wages already paid, distributions, profit, and the work you performed. They can determine whether a correction is permitted and how to document it. A later adjustment may not erase an earlier underpayment.
My practice offers a 401(k); should I raise salary before increasing my retirement contribution?
Review the salary first, but do not raise it solely to increase a 401(k) contribution. The plan terms, annual limits, practice cash needs, and the work you perform all matter. Ask your CPA and plan professional to model the added contribution against payroll taxes and cash reserves before changing payroll.
What records help show that my dental salary matches my work?
Keep clinical hours, management duties, payroll reports, practice revenue, distributions, comparable wage information, and a written explanation of the salary decision. The record should show who performs each role, how often, and what the practice would pay for that work. Update it when workload, profit, or ownership changes.
