September 15 is behind you. Extended S corporation returns are filed or on extension, and Q3 estimates are handled. For Chicago-area fleet owners, livery operators, and other S corporation shareholders who work in the business, the next calendar move is your 2026 W-2 salary. Reasonable compensation has to run through payroll before December 31. You cannot fix it with a January journal entry.
Why the salary line matters
An S corporation can pay you a salary and also make distributions. Only the W-2 wages carry Social Security and Medicare tax. Distributions generally do not. That split is why owners are tempted to set pay low and take the rest as a draw. The IRS expects officer-shareholders who perform services to take a reasonable salary for the work before treating remaining profit as a distribution. Set it too low and the agency can recharacterize distributions as wages, assess back payroll tax, and add penalties and interest. Set it without documentation and you have a thin file if questions arrive.
The salary also feeds Form W-2, Form 941, the officer compensation line on Form 1120-S, and often the wage base that supports a qualified business income (QBI) deduction analysis. Those forms should tell the same story.
What "reasonable" looks like in practice
There is no single IRS table that names your number. In practice, a supportable figure weighs the work you do, hours, skills, and what comparable roles pay in your market. For a metro Chicago trucking or logistics S corp, that might mean looking at dispatcher, operations, or driver-manager pay ranges when the owner fills those seats. Duties, time spent, and industry comps belong in a short memo in the corporate file, not only in someone’s head.
Payroll has to match the decision. If your last scheduled payroll of the year is mid-December, plan an extra run or a year-end bonus so the W-2 lands where you intend. Employee elective deferrals into a 401(k) also have to come out of 2026 paychecks by December 31. Employer contributions often have more time, but the salary itself does not wait for the tax-return deadline.
Illustration (not your books)
Example (illustration only): An Illinois S corporation owns three trucks. The shareholder-owner runs dispatch, bids loads, and drives when short-handed. The company shows $220,000 of profit before officer pay. The owner takes $18,000 of W-2 wages and $180,000 of distributions. In an exam, the agent asks how $18,000 is reasonable for full-time operations and driving work in the Chicago market. Comparable pay data sits far higher. Distributions get recharacterized as wages. The company owes back employment tax, and the owner’s personal return has to be corrected. The same owner who set a documented salary tied to duties, hours, and local comps, then ran it through payroll before year-end, has a file that can be explained.
What to lock down this fall
- Project 2026 profit with nine months of actual books, not a December guess
- Write a short reasonable-compensation memo (role, hours, comps, chosen salary)
- Confirm the payroll calendar can deliver that W-2 total by December 31
- Coordinate shareholder health premiums and retirement deferrals with the same pay runs
- Keep distributions after wages are set, and keep K-1, W-2, and 1120-S lines consistent
Illinois S corporations should also keep an eye on pass-through entity (PTE) tax estimates and the annual election timing on the Illinois return. Federal salary decisions and state PTE cash needs often sit on the same fall calendar, so treat them together when you plan cash.
