If you own an S corporation and work in it, the IRS expects you to pay yourself a reasonable salary for the work you do before you take profit out as distributions. "Reasonable" means roughly what the business would pay someone else to do your job. It matters because salary carries payroll tax and distributions do not, so the number you pick affects your tax bill, your retirement savings and how your return looks if anyone asks.
What does "reasonable salary" mean to the IRS?
There is no formula in the tax code. The IRS looks at the facts. Its guidance on S corporation compensation lists the kinds of factors it weighs, including:
- Your training and experience, and the duties and time you put in.
- What comparable businesses pay for similar services.
- The business's gross receipts, expenses and distribution history.
- Who brings in the revenue: your personal work, or employees and capital.
Courts have backed the IRS when the salary was clearly too low. In Watson v. United States (8th Cir. 2012), an accountant who paid himself $24,000 while taking far larger distributions had a large part of those distributions reclassified as wages, with payroll tax owed on them.
Why does the salary change your tax bill?
Salary is subject to Social Security and Medicare tax. Distributions are not. For 2026, Social Security tax of 6.2% from both employer and employee applies to wages up to $184,500 (Social Security Administration, October 2025). Medicare tax of 1.45% each applies to all wages, plus an extra 0.9% on wages above $200,000 for a single filer or $250,000 for a married couple filing jointly.
So a lower salary saves payroll tax. That is why some owners push it as low as they dare. But payroll tax is only one of the numbers the salary moves.
The lowest salary is rarely the best one. The best one balances four numbers at once.
How does salary interact with the QBI deduction?
Many owners can deduct up to 20% of their qualified business income (QBI). Your salary is not QBI, so a higher salary shrinks the base. Above an income threshold, though, the deduction can be limited to a share of the W-2 wages the business pays, and your own salary counts as W-2 wages. For 2026 that limit starts phasing in above $201,775 of taxable income for single filers and $403,500 for married couples filing jointly (IRS, Rev. Proc. 2025-32). At those incomes, paying yourself too little can cost you deduction. We cover the deduction itself in the QBI deduction for owners.
How does salary affect retirement contributions?
In a solo 401(k) or other employer plan, the business can contribute a percentage of your W-2 salary. Distributions do not count. A very low salary can cap how much you are able to shelter. For 2026 the IRS limits are $24,500 for employee deferrals, an $8,000 catch-up from age 50 ($11,250 for ages 60 to 63), and $72,000 for total annual additions to one person's account, not counting catch-ups (IRS, November 2025). For many owners, the salary that maximizes plan room is higher than the salary that minimizes payroll tax.
What about state tax and the PTET?
Utah taxes wages and S corporation profit at the same flat individual rate, so the split between them matters less for Utah tax than for federal payroll tax. If the business elects into Utah's pass-through entity tax, though, the entity pays the Utah tax on profit, and that interacts with the salary and the QBI calculation. Our post on Utah's PTET covers that election.
A hypothetical example
Hypothetical. Two Utah owners each run an S corporation with the same profit. One pays herself a salary well below what she would pay a replacement, to save payroll tax. The other pays himself a market salary and uses it to make full solo 401(k) contributions. The first saves some payroll tax but shelters less for retirement and carries more risk of reclassification if the return is examined. The second pays more payroll tax this year but defers income tax on the plan contributions and can document how the salary was set. Neither is automatically right. The point is that the answer comes from the whole picture, not from payroll tax alone.
How often should the salary be revisited?
Every year, and whenever the business changes. Profit grows, you hire someone to do part of your job, you add a retirement plan, the wage base moves, or tax law changes. Each of those can move the reasonable number. Writing down how you arrived at it, with comparable pay data, is also the best defense if the IRS ever asks.
