S-Corp Owners: Getting the Salary-vs-Distribution Split Right

Most S-corp owners discover the payroll-tax savings first and design the rest of the structure around protecting them. That instinct isn't wrong, but it is incomplete. The salary number you land on doesn't just affect your FICA bill. It sets the ceiling on your retirement contributions, shapes your Qualified Business Income deduction, and determines whether an IRS auditor closes your file in ten minutes or orders a full payroll review.

What "Reasonable Compensation" Actually Means

The IRS requires S-corp owner-employees to take a salary that a similarly qualified person would earn performing the same services in an arm's-length transaction. That phrase sounds fuzzy because it is. There's no published safe-harbor number, no table you look up. What the IRS actually weighs includes: what the market pays for the services you personally perform, your time spent in the business relative to others who share duties, the training and experience you bring, the company's revenue and profitability, and comparable wages in your industry and geography.

The audit red flag isn't a low salary in isolation. It's a pattern: high distributions, minimal wages, a profitable company, and compensation that looks nothing like what a hired replacement would command. That combination is the one that draws scrutiny. An owner of a $2 million consulting firm who pays herself $45,000 and takes $400,000 in distributions is not in a defensible position.

Where the Salary Decision Gets Expensive to Get Wrong

Here is the part most planning conversations miss. Your W-2 salary from the S-corp is the foundation for two other numbers that matter a great deal.

Retirement plan contribution room. Solo 401(k) employee deferrals and employer profit-sharing contributions are both tied to W-2 compensation from the S-corp. In 2026, the employee deferral limit is $23,500 (plus a $7,500 catch-up if you're 50 or older). The employer side can reach up to 25% of W-2 wages. Set the salary too low to minimize FICA and you quietly compress the tax-advantaged space you can use to build a real retirement. An owner earning $80,000 in W-2 wages has a materially different contribution ceiling than one earning $180,000, and the compounding difference over a decade is not trivial.

The QBI deduction. For S-corp owners whose business qualifies, the Section 199A deduction can shelter up to 20% of qualified business income from federal income tax. But above certain income thresholds, the deduction gets limited based partly on W-2 wages paid. A salary that's too low can actually shrink the deduction you'd otherwise be entitled to, costing you on one side while you're trying to save on the other. These interactions are why this decision belongs in the Soil layer of a real financial plan, not on a tax return that gets filed and forgotten.

What to Do Before Year-End

The salary-distribution split shouldn't be set once and left alone. If your business revenue has grown significantly since you last revisited it, your compensation may no longer hold up under IRS scrutiny and your retirement contribution room may be needlessly constrained.

My suggestion: before Q4, sit down with your CPA and your financial planner together and run the numbers in both directions. What does a defensible compensation figure look like for your role and your industry? And given that figure, how much retirement contribution room opens up, and what does the QBI math look like?

If you'd like to think through how this connects to the broader structure of your retirement plan, that's a conversation worth having. You can start here to see how we approach it.
