Reasonable Compensation: The S-Corp Rule That Decides Whether It Works

Every S-corp article tells you the saving comes from taking part of your profit as distributions rather than salary.

Almost none of them spend time on the constraint that decides whether any of it works.

The rule

An S corporation must pay reasonable compensation to a shareholder-employee for services performed, before non-wage distributions are made.

The IRS states this directly, and the Form 1120-S instructions go further: distributions to a corporate officer "must be treated as wages to the extent the amounts are reasonable compensation for services rendered."

Note the direction of that sentence. It does not say you should pay a reasonable salary. It says amounts you call distributions get treated as wages if they were really compensation.

There is no percentage

The 60/40 rule you have read about is not in the tax code. Neither is 50/50, nor any other split. They are heuristics invented by people selling formation services.

What the IRS actually examines is the source of the company's gross receipts:

1. Income generated by the shareholder's personal services
2. Income generated by non-shareholder employees
3. Income generated by capital and equipment

A solo consultant with no employees and no meaningful capital generates essentially all revenue from category one. That is a hard position from which to argue most of the money was a return on investment rather than pay for work.

How to actually set it

The defensible approach is to answer one question in writing: what would it cost to hire someone to do what I do?

That means:

• A real job title for the work you perform
• Salary data for that role, in your market, at your experience level
• An honest split if you do several roles — delivery, sales, admin
• The hours you actually work, if it is not full-time
• A note of anything unusual about your market or specialism

Then keep it. A one-page memo written contemporaneously, with sources, is worth considerably more than a number you can no longer explain three years later.

The two failure modes

Too low is the famous one. The IRS reclassifies distributions as wages and assesses back employment taxes, plus penalties and interest. Courts have consistently sided with the IRS here.

Too high is the quiet one. Every dollar of salary is a dollar of payroll tax you did not need to pay, and — because wages are not qualified business income — a dollar that no longer qualifies for the Section 199A deduction. Over-caution has a price too.

The compounding problem

Two things make the low-salary strategy worse than it looks:

Social Security. Your eventual benefit is calculated from your 35 highest-earning years. Report a small salary for a decade and you have permanently reduced it.

Retirement contributions. Solo 401(k) employer contributions are calculated from W-2 wages in an S-corp. A low salary shrinks how much you can shelter — which can cost more than the payroll tax it saved.

Before you elect

Work out the breakeven with a salary you would be comfortable defending in writing, not the one that maximises the saving.

If the election only works at a salary you would rather not have to justify, that is the calculation telling you something. The S-corp is not free money; it is a trade of administrative cost and audit exposure for payroll tax, and it only pays when the margin is wide enough to absorb an honest salary.
