S Corp Reasonable Salary: How to Set It, Document It, and Defend It

Most S corp owners set their salary by looking at what's left after distributions. That's the wrong end to start from. A reasonable S corp salary is what the company would have to pay someone else to do the work you personally do for it. The IRS does not publish a percentage, a ratio, or a safe-harbor number. The method that holds up is to price each role you actually perform, weight it by the hours you spend in it, and keep the file that shows how you got there.

That frustrates owners who were told "pay yourself 40% and take the rest as distributions." The 40% rule has no source in the Code or in IRS guidance. It survives because it is easy to remember, not because it is defensible.

What the IRS actually says

The IRS page on S corporation compensation and medical insurance issues is short and blunt. An S corporation must pay reasonable compensation to a shareholder-employee for services before making non-wage distributions. When gross receipts are generated by the shareholder's personal services, payments to that shareholder should be classified as wages. The IRS can reclassify distributions as wages and assess employment tax on them.

The factors the IRS lists include training and experience, duties and responsibilities, and what comparable businesses pay for similar services. Every one of them is about the work, not about how much profit is left over.

The Form 1120-S instructions repeat the point for officers: distributions and other payments to a corporate officer must be treated as wages to the extent they are reasonable compensation for services. If total receipts are $500,000 or more, the company also completes Form 1125-E, and that figure flows to Form 1120-S line 7, Compensation of officers. In other words, the number is on the face of the return.

The replacement-cost method

Bennett's approach is to stop asking "what percentage of profit?" and ask "what would I pay to replace myself, role by role?" Most owners of a $2M-$15M service business are doing three or four jobs at once. Each of those jobs has a market price.

1. List the roles you perform: CEO, rainmaker, lead practitioner, operations manager, billable producer.
2. Estimate the share of your working hours in each role over a normal year.
3. Find a market salary for each role at a company of your size and region. Use a salary survey, recruiter data, or the actual offers you have made to similar hires.
4. Multiply each market salary by your share of hours and add the results.
5. Compare the total with what you pay your highest-paid non-owner employee. If you pay yourself less than your senior account director, you need a reason.

An illustrative replacement-cost table

The figures below are hypothetical, for a $3M marketing agency whose S corporation earns $600,000 before the owner's salary.

That $156,000 is the starting point, not the answer. If the owner also holds a license the business depends on, or personally delivers most of the revenue, the number moves up. If a general manager actually runs operations and the owner works 25 hours a week, it moves down.

If your W-2 sits well below what it would cost to replace you, the real question is whether the payroll tax you're saving is worth the exposure. Bring last year's salary and distribution totals to a Leak Check and get a directional answer on that trade, including what the salary is doing to your QBI deduction.

What a lower salary really saves in 2026

Owners underpay themselves to save payroll tax, so do the arithmetic honestly. For 2026, IRS Publication 15 sets the Social Security wage base at $184,500, with 6.2% Social Security tax on both the employee and the employer and 1.45% Medicare on each, with no Medicare wage cap.

Using the hypothetical agency above, compare an $80,000 salary with the $156,000 replacement-cost salary:

Salary gap:                          $156,000 - $80,000 = $76,000
Combined Social Security (12.4%):    $76,000 x 0.124   = $9,424
Combined Medicare (2.9%):            $76,000 x 0.029   = $2,204
Annual payroll tax "saved":                              $11,628

That $11,628 is the entire prize, before state unemployment and payroll-provider costs move it slightly. Against it, the owner is carrying the risk that $76,000 a year of distributions gets reclassified as wages, with the employment tax, penalties, and interest that follow. The IRS interest rate on individual underpayments was 7% for the fourth quarter of 2026, compounded daily.

The math changes above the wage base. Once salary passes $184,500, the 12.4% Social Security portion stops. Each extra dollar of salary costs 2.9% in Medicare, plus the 0.9% Additional Medicare Tax that IRS Topic 560 applies above $200,000 of wages (single) or $250,000 (married filing jointly). For a high earner, being defensible is cheap.

The Bennett decision rule follows from that: when the replacement-cost salary is above the wage base, there is very little reason to shave it. Shaving a salary that sits below the wage base has a bigger payoff, so the documentation has to be correspondingly stronger.

The QBI side of the trade-off

Salary is not only a payroll-tax decision. Wages paid to you reduce the S corporation's qualified business income, which reduces the 20% QBI deduction. Above certain income levels, though, the W-2 wages the company pays can also support the deduction.

Rev. Proc. 2025-32 sets the 2026 section 199A threshold at $403,500 for joint filers and $201,750 for most other filers, with phase-in ranges ending at $553,500 and $276,750. Below the threshold, a higher salary simply shrinks QBI. Inside or above the range, the wage limitation and the specified-service rules come into play, and the best salary can be higher than the payroll-tax math alone suggests. Our earlier breakdown of the QBI deduction for service businesses covers those mechanics.

Run both calculations together. A salary set only to minimize FICA can cost more in lost QBI than it saves.

Build the file before December

A defensible salary is one you can explain three years from now to someone who wasn't in the room. Keep:

• The role table. Roles, hours share, market salaries, and the source of each salary figure.
• A board or owner resolution. A short written approval of the salary for the year, with the date.
• Comparable data. Survey pages, recruiter quotes, or offer letters for similar roles. Save the actual documents, not a note that you looked.
• Payroll that looks like payroll. Regular pay periods with withholding and deposits, not a single December check sized to whatever cash was left.
• Health insurance on the W-2. Premiums the company pays for a more-than-2% shareholder go in Box 1 wages but not Boxes 3 and 5, per the IRS S corporation compensation page. The 1120-S instructions also have the premiums shown in Box 14 of the shareholder's W-2.

If you're still deciding whether the S election is worth having at all, start with our comparison of S corp vs LLC taxes. The salary question only exists once you've made that call.

Patterns that invite a second look

None of these automatically triggers reclassification, but each one makes the file harder to defend:

• No salary at all in a year with meaningful distributions.
• An owner salary below the pay of the owner's own direct reports.
• Distributions several times larger than salary in a firm where the owner is the main producer of revenue.
• A salary that never changes while revenue doubles.
• Salary paid in one lump at year-end with no payroll the rest of the year.

The order of payments matters too. Paying distributions first and salary "if there's anything left" is backwards. For a vertical example, our piece on structuring plastic surgery owner distributions walks through why the sequence affects both tax and cash.

When to revisit the number

Reset the salary when the facts behind the role table change. Typical triggers:

• You hire a general manager or COO and step out of daily operations.
• Revenue grows enough that the market price of "CEO of a company this size" moves.
• You stop billing client work and move into business development only.
• Your spouse joins payroll, or a second shareholder starts drawing distributions.

A mid-year change is fine as long as the resolution and payroll records show when and why it happened.

Reasonable compensation is one piece of the owner-pay structure. Retirement contributions, health benefits, accountable-plan reimbursements, and estimated tax payments all hang off the salary figure, which is why our fractional CFO services set it inside the annual forecast instead of leaving it to the payroll provider's default.

Build the role table while there are still payrolls left this year, multiply it out, and put the total next to your W-2 year-to-date. If the gap is more than a few thousand dollars, or you have no file at all, bring both numbers to a Leak Check conversation and get a read on whether the gap is costing you more in risk than it saves in payroll tax.
