How to set a reasonable S-corp salary you can actually defend

An S corporation saves you money through a single mechanism: profit taken as distributions escapes Social Security and Medicare tax, while profit taken as wages does not. The obvious move is to pay yourself almost nothing and take everything as distributions. That move is also the single most reliable way to lose an audit.

Under IRC §3121(d)(1) an officer who performs more than minor services is an employee, and the corporation must pay them wages. The IRS has been explicit for decades — most directly in Rev. Rul. 74-44 — that distributions paid in lieu of reasonable compensation will be recharacterised as wages, with back payroll tax, interest and penalties attached.

There is no safe harbour, and anyone who tells you otherwise is guessing

You will see the 60/40 rule quoted constantly: 60% salary, 40% distributions. It appears nowhere in the Internal Revenue Code, the regulations, or any revenue ruling. Neither does 50/50, nor the “$40,000 is always safe” claim. Reasonable compensation is a facts-and-circumstances test, which means the answer depends on your business and not on a ratio someone posted.

What the rules of thumb are useful for is calibration. Across the case law and practitioner practice, defensible salaries cluster between roughly 30% and 60% of net profit, weighted toward the higher end when profit is modest and almost entirely attributable to your own labour, and toward the lower end when profit is large and driven by leverage, capital, employees or intellectual property you own.

What a court actually weighs

Courts consistently return to the same factors. Work through them honestly and you will have both a number and the reasoning to support it:

• Training and experience. What does someone with your credentials command in the open market?
• Duties and hours. Are you full-time? Doing the billable work, or managing people who do it?
• What the business pays everyone else. A salary well below your own employees is difficult to justify.
• What comparable businesses pay. Bureau of Labor Statistics data by occupation and metro area is free, specific, and exactly the sort of evidence that holds up.
• How profit is actually generated. This is the decisive one. Profit that comes from your billable hours is compensation. Profit that comes from capital, a team, or a product that earns while you sleep is a return on the business, and belongs in distributions.
• Timing and consistency. Regular payroll across the year looks like a salary. A single December lump sum looks like an afterthought.

A method that produces a number

1. Price the job, not the profit. Find the market rate for what you do, in your city, at your level of experience. BLS wage data and a couple of live job postings are enough. Write the figure down and keep the sources.
2. Adjust for how much you actually work. Half-time in the business means roughly half the market rate.
3. Split the profit by its source. Estimate how much comes from your personal services versus capital, employees or products. The services portion is the compensation floor.
4. Sanity-check the ratio. If the result is under 30% of profit, expect to justify it. Under 20% and you should have a genuinely strong story about non-labour profit.
5. Write down the reasoning. One page, dated, kept with your tax records, revisited annually. In an examination the difference between a defensible position and an expensive one is usually whether contemporaneous reasoning exists.

Practical points that cost people money

Run payroll on a schedule

Quarterly or monthly, through an actual payroll service that files your 941s and issues a W-2. A single year-end entry invites the argument that no genuine employment relationship existed.

Health insurance has its own rule

Premiums for a more-than-2% shareholder must be paid or reimbursed by the corporation and included in W-2 box 1 wages — though not in Social Security or Medicare wages. Handle it before the final payroll of the year or you lose the above-the-line deduction on your personal return.

Your salary caps your retirement contributions

The employer side of a solo 401(k) is limited to 25% of W-2 compensation. A very low salary can quietly cost you more in lost tax-deferred contribution room than it saved in payroll tax. Switch the retirement setting on in the calculator to see the trade for your figures.

Do not let the salary drift

Revisit it every year. A salary that was defensible at $90,000 of profit is not automatically defensible at $400,000, and stale numbers are easy for an examiner to spot.
