Once you’ve made the S-corp election, one number does most of the work: your salary. Set it well and the election does what you elected it to do. Set it wrong — usually too low — and you’ve handed the IRS the easiest reclassification case it’ll see all year.
Here’s how the salary actually drives the math, what “reasonable” means to the people who audit it, and how to land on a number you can defend.
Why the salary number is the whole ballgame
An S-corp splits your pay into two buckets. The salary runs through payroll and gets hit with payroll taxes — 7.65% from the company and 7.65% from you, 15.3% combined, on the Social Security and Medicare wages (the Social Security piece stops at the $184,500 wage base in 2026; Medicare keeps going). The distribution is the rest of the profit, and it doesn’t carry that 15.3%.
That gap is the entire reason the election saves money — and the exact reason the IRS watches it. Every dollar you move from “salary” to “distribution” is a dollar that skips payroll tax. The lower you set the salary, the bigger the savings and the bigger the target on your return.
What “reasonable” actually means to the IRS
There is no magic percentage. No 60/40 rule, no 50/50 rule — those are internet folklore, not tax law. The standard is “reasonable compensation,” and the IRS judges it on the facts of what you do, drawing on the same factors the courts use:
- Your training, experience, and qualifications.
- The duties and responsibilities you actually carry.
- The time and effort you devote to the business.
- What comparable businesses pay for similar work.
- How profit is split between wages and distributions, and what you pay non-owner employees doing similar work.
The plain-English version: what would you have to pay someone else to do your job? That replacement cost is your anchor.
Before you lock in a salary, see what the split is actually worth at your profit level — payroll and compliance costs included. That's the number the decision should hang on.

The fastest way to unwind your own election in an audit is to pay yourself a tiny salary — or zero — and take everything as distributions. The IRS doesn’t have to prove a “right” number; it just has to show yours was unreasonably low, then reclassify distributions as wages and pile on back payroll taxes, penalties, and interest.
This isn’t theoretical. In the most-cited case on the subject, a CPA paid himself a $24,000 salary while pulling far more out of his firm as distributions. The courts backed the IRS in treating roughly $91,000 of that as wages — and the bill followed. A round number you picked because it “felt safe,” or a figure you copied from a friend in a different line of work, is not a defense.
How to actually set it
- Start from market replacement cost. Look up what your role pays — BLS wage data, industry salary surveys, or a formal reasonable-compensation analysis for a closer call.
- Match it to what you really do. A working owner who runs the whole operation justifies a higher salary than a passive owner; weight it to your actual hours and duties.
- Write down your reasoning. Keep the comp data and the logic on file. Reasonable is a fact question — documentation is how you win it.
- Revisit it every year. Profit grows, your role changes, wage bases move. Last year’s number isn’t automatically this year’s.
Too high is also a mistake
The error runs both directions. Pay yourself more salary than the work warrants and you’ve voluntarily run profit through the 15.3% you elected the S-corp to avoid — quietly giving back the savings. The goal isn’t the lowest salary you can imagine or the highest you can stomach. It’s a defensible one, sitting where the facts put it.

Setting a reasonable salary — and running the payroll that backs it up — is exactly the kind of thing worth getting right the first time, not after a notice arrives.
