What is reasonable compensation for S-corp shareholders?

Reasonable compensation is the salary an S-corp must pay its shareholder-employees under IRC §162 before taking distributions. It must reflect what an unrelated third party would pay for the same services, based on duties, experience, time, comparable salaries, company size, and economic conditions.

What happens if an S-corp doesn't pay reasonable compensation?

The IRS can reclassify distributions as wages, triggering back employment taxes (Social Security + Medicare), interest, and penalties. The IRS actively targets S-corps with zero or artificially low shareholder salaries.

What factors does the IRS consider for reasonable compensation?

The IRS evaluates six primary factors: (1) duties and responsibilities, (2) time and effort devoted to the business, (3) training and experience, (4) comparable salaries in the market, (5) company size and complexity, and (6) local economic conditions.

What is Reasonable Compensation? A CPA's Guide to IRC §162

For CPAs advising S-corporation clients, few topics generate as much uncertainty as reasonable compensation. The IRS requires shareholder-employees to pay themselves a "reasonable" salary before taking distributions, but what exactly does "reasonable" mean?

This guide breaks down the legal requirements, IRS factors, and practical approaches to determining defensible compensation for your S-corp clients.

The Legal Foundation: IRC §162 and Employment Taxes

The reasonable compensation requirement stems from Internal Revenue Code Section 162, which allows businesses to deduct "ordinary and necessary" expenses—including compensation for services rendered. For S-corporations, this intersects with employment tax rules.

Unlike distributions, which flow through to shareholders without employment taxes, salary payments are subject to:

Social Security

6.2% employer + 6.2% employee (up to wage base)

Medicare

1.45% employer + 1.45% employee

Additional Medicare

0.9% on wages over $200,000

Income Tax Withholding

Federal and state withholding applies

The core tension

Shareholders want to minimize salary (and employment taxes) while maximizing distributions. The IRS, however, has consistently challenged arrangements where salaries appear artificially low. Getting this balance right is critical for S-corp salary vs. distribution planning.

What the IRS Considers "Reasonable"

The IRS and courts have developed several factors for evaluating reasonable compensation. While no single factor is determinative, these considerations guide the analysis:

Duties and Responsibilities

What does the shareholder actually do for the company? Executive-level responsibilities (strategic planning, major decisions, client relationships) command higher compensation than routine tasks.

Time and Effort

How many hours does the shareholder devote to the business? Full-time involvement suggests higher compensation than passive or part-time roles.

Training and Experience

Education, certifications, and industry experience affect market value. A shareholder with specialized expertise (CPA, attorney, engineer) may command premium compensation.

Comparable Salaries

What do similar positions pay in the market? Bureau of Labor Statistics data, industry surveys, and comparable company analysis provide benchmarks.

Company Size and Complexity

Managing a $10 million company differs from managing a $500,000 company. Compensation should reflect the scope of responsibility.

Economic Conditions

Local cost of living, industry conditions, and the company's financial health all influence reasonable compensation.

"The key is documentation. If you can clearly articulate why a salary amount is reasonable based on these factors, you're in a much stronger position if questioned."

Common Mistakes to Avoid

In our experience working with CPAs, these are the most common reasonable compensation pitfalls:

Zero or minimal salary

Taking only distributions is a red flag the IRS actively pursues.

Inconsistent compensation

Wildly varying salaries year-to-year without business justification raises concerns.

Salary below market minimums

Paying less than entry-level wages for executive work invites scrutiny.

No documentation

Having no written analysis or rationale for the chosen salary leaves you exposed. See our documentation best practices guide.

Ignoring local factors

Using national data without geographic adjustments understates or overstates the range.

Building a Defensible Position

The best defense against IRS scrutiny is proactive documentation. Here's what we recommend:

Document duties annually

Maintain a written job description for each shareholder-employee.

Use market data

Reference BLS wage data or salary surveys for comparable positions.

Consider multiple factors

Don't rely on a single benchmark; analyze several factors from the IRS framework.

Create a written analysis

Document your methodology and reasoning in a defensible file.

Review annually

Update compensation as duties or market conditions change each year.

Audit preparation starts now

Documentation created during an audit carries far less weight than records prepared contemporaneously. Build the file before you need it. Learn more in our guide to defending reasonable compensation in an IRS audit.
