Reasonable salary for S corp owners: how to set it and defend it

Why the rule exists

S corp distributions aren’t subject to Social Security and Medicare taxes. Salary is. Without a rule, every owner would pay themselves nothing and take everything as distributions.

So the IRS requires S corporations to pay reasonable compensation to shareholder-employees for the services they provide before taking distributions. Pay yourself too little and the IRS can recharacterize distributions as wages, then assess the payroll taxes you skipped, plus penalties and interest.

There’s no published formula or safe percentage. The popular “60/40” split is a rule of thumb, not IRS guidance.

What the IRS looks at

Reasonableness depends on the facts. Factors the IRS lists, drawn from court cases, include:

• Your training, experience, and education
• Your duties and responsibilities
• The time and effort you devote to the business
• Dividend and distribution history
• What the business pays non-owner employees
• What comparable businesses pay for similar services
• Compensation agreements and any formula used to set pay

Three ways to set the number

The IRS also looks at the source of the company’s income. Profit generated by your own personal services points toward a higher salary. Profit generated by employees, equipment, or capital supports a lower salary relative to total profit.

That’s why a solo physician, attorney, or consultant with no staff will have a hard time defending a small salary: nearly all of the profit comes from their own work. An owner of a firm with ten billing employees has more room, because much of the profit comes from other people’s labor.

The underlying question is simple: what would this business have to pay someone else to do what you do? Most defensible salaries come from one of these approaches, or a blend:

• Market approach: use wage data for your role, region, and experience level, such as Bureau of Labor Statistics occupational wage surveys or industry compensation studies.
• Cost approach: if you wear several hats, split your time into roles (for example, lead consultant, sales, and bookkeeping) and price each at its market rate for the hours you spend on it.
• Income approach: estimate the return an outside investor would expect from the business’s capital, and treat the rest of the profit as pay for your work.

A worked example: $250,000 of profit

A consultant’s one-person S corp earns $250,000 of profit before owner pay in 2026. Market data for her role and region supports roughly $120,000 to $140,000. She’s considering $70,000 instead.

The difference between a $70,000 and $120,000 salary is $50,000 of wages. Both amounts are under the 2026 Social Security wage base of $184,500, so the extra payroll tax is about $7,650 ($50,000 × 15.3%). That’s the most the lower salary saves each year.

A quick income-approach check points the same way. Her business has almost no equipment or capital, and no staff, so an outside investor would expect little return from it. Nearly all of the $250,000 is pay for her own work, which argues for the upper end of the market range rather than the bottom.

Now the downside. If the IRS reclassifies $50,000 of distributions as wages, it can assess that $7,650 plus penalties for failing to deposit and report payroll taxes, and interest going back to the original due dates — often across several years at once.

The lower salary also costs her retirement room. In a solo 401(k), the employer contribution is generally limited to 25% of W-2 wages: $17,500 at a $70,000 salary versus $30,000 at $120,000. Add the 2026 employee deferral limit of $24,500, and her total drops from $54,500 to $42,000.

Balancing the tradeoffs

Lower isn’t automatically better. Salary builds your Social Security earnings record and sets the base for employer retirement contributions.

It also interacts with the qualified business income (QBI) deduction. Your salary isn’t QBI, so a higher salary shrinks the deduction. But above the 2026 income thresholds ($201,750 single, $403,500 married filing jointly), the deduction for many businesses is capped by W-2 wages paid — including your own — so a higher salary can sometimes increase it. For specified service fields like consulting, law, and medicine, the deduction phases out entirely at higher incomes, which removes this factor.

If salary would exceed the Social Security wage base, savings shrink to the 2.9% Medicare portion, plus the 0.9% Additional Medicare Tax on wages above $200,000 (single) or $250,000 (married filing jointly).

Run it through payroll correctly

A reasonable number only helps if it’s paid the right way:

• Run salary through actual payroll with federal and state withholding, not ad hoc transfers labeled “salary.”
• Deposit payroll taxes on schedule and file Form 941 quarterly, Form 940 annually, and W-2s by January 31.
• Pay it regularly through the year rather than as a single December catch-up.
• If the company pays health insurance for a more-than-2% shareholder, include the premiums in W-2 Box 1 wages (they’re exempt from Social Security and Medicare). That’s what lets you claim the self-employed health insurance deduction.
• Take distributions in proportion to ownership if there’s more than one shareholder.

How to defend it

The best defense is paperwork created when you set the salary, not after a notice arrives.

• Write a short memo explaining the method, data sources, and resulting figure.
• Keep copies of the wage data you relied on.
• Record the salary in owner or board minutes, even for a one-person company.
• Revisit it annually, and whenever your role, hours, or profit change significantly.
• Avoid patterns that invite questions: zero salary with large distributions, or salary that stays flat while profit doubles.

When to revisit the number

Reasonable compensation isn’t a one-time decision. Plan to review it at least once a year, ideally in the fourth quarter when you can see the year’s profit, and whenever something material changes:

• You hire staff who take over work you used to do, which can support a lower salary.
• You move from part-time to full-time in the business, or the reverse.
• Profit jumps because of your own production rather than other people’s work.
• A second owner joins, and salaries need to reflect each person’s actual role.
• Market pay for your profession changes meaningfully.

Multiple owners, family members, and common mistakes

Each shareholder who works in the business needs reasonable pay for their own role; a passive investor who provides no services doesn’t. Salaries can differ between owners, but distributions must follow ownership percentages, so you can’t use distributions to make up for pay differences.

If a spouse or family member is on payroll, their pay should match the work they actually do, with timesheets or job descriptions to back it up.

The errors we see most often in S corp reviews at Tally Tax are simple ones: no salary at all in the first year after the election, salary set once and never revisited, and owner draws recorded as salary without payroll filings. Each is fixable, and fixing it before an examination is far cheaper than after.

If you realize mid-year that salary has been too low, the cleanest fix is usually to increase payroll for the remaining pay periods rather than recording a lump sum at year-end. If prior years are the problem, talk to a preparer about whether amended payroll filings make sense before the IRS raises it.
