The S-corp election saves payroll tax by splitting owner income into salary (taxed with FICA) and distributions (not). That split is policed by exactly one rule: the salary must be reasonable compensation for the work you actually perform. Set it defensibly and the election's savings are durable. Set it by wishful thinking and the IRS has decades of case law, and a 15.3% incentive, on its side.
What "Reasonable" Means in Practice
The standard comes from the same body of law that governs executive compensation: what would a comparable business pay a non-owner to perform your duties? The factors courts and the IRS weigh consistently: your training and experience, duties and responsibilities, time devoted to the business, what comparable businesses pay for comparable roles, the company's revenue and complexity, and what portion of profits comes from your labor versus capital, staff, or systems.
That last factor is why no ratio rule can exist. A solo consultant whose billings are entirely personal labor should expect most profit to be salary. An e-commerce owner whose profit flows from inventory, systems, and contractors performs a manager's job, and a manager's market salary, with genuine distributions above it, is defensible. Same profit, different answers, both reasonable.
Building the Number in Four Steps
A worked example. An agency owner nets $180,000, working full-time as strategist and manager while three contractors deliver. Market data prices her blended role at $85,000 to $95,000 in her metro. She sets $90,000 in salary through payroll, takes the remaining $90,000 as distributions, and files the memo. FICA applies to half her income instead of all of it: roughly $6,000 to $7,000 saved annually, on a number she can defend in one email.
Contrast the folklore version: same owner, $30,000 salary because a forum said "just pay yourself something." The $150,000 of distributions on a token salary is precisely the pattern reclassification cases are made of, and the true savings difference between $30K and $90K salary is far smaller than the penalty exposure it creates.

What Reclassification Costs
When the IRS recharacterizes distributions as wages, the bill stacks: both halves of FICA on the reclassified amount, failure-to-deposit and failure-to-file penalties on the payroll returns that should have existed, interest from the original due dates, and in egregious cases the 100% trust-fund recovery penalty against the owner personally. Multiply across the three open audit years and a $20,000 annual "savings" becomes a six-figure problem. The defense is never clever structuring; it is a salary a stranger would recognize as a fair wage for the job, documented before anyone asked.
How the IRS Actually Tests the Number
There is no safe harbour, no published table and no ratio. What exists is a list of factors the IRS names on its own S corporation compensation page, and a line in the Form 1120-S instructions that does the real work: distributions and other payments by an S corporation to a corporate officer must be treated as wages to the extent the amounts are reasonable compensation for services rendered.
The factors the IRS lists are training and experience; duties and responsibilities; the time and effort actually devoted to the business; dividend history; what the company pays non-shareholder employees; the timing and manner of bonuses to key people; what comparable businesses pay for similar services; any compensation agreement; and whether a formula is used to set pay. Read them together and a pattern emerges: every one of them asks what the market would pay a stranger, and none of them asks what the owner would prefer.
The authority to act on that is explicit. The IRS can reclassify payments made to shareholders from non-wage distributions to wages, and the case law behind it is long and one-sided. Joly v. Commissioner established the authority. Veterinary Surgical Consultants and Joseph M. Grey Public Accountant settled that a working shareholder is an employee. David E. Watson, PC v. United States, decided by the Eighth Circuit in 2012, is the one most often cited to owners, because an accountant taking $24,000 in wages against roughly $200,000 of distributions had his compensation reset to $91,044 for each of two years.
One 2026 number changes the shape of the decision more than most owners expect. The Social Security wage base is $184,500. Below it, each additional dollar of salary costs 15.3 percent in combined employment tax. Above it, Social Security stops and only the 2.9 percent Medicare component continues, plus the 0.9 percent additional Medicare tax on wages above $200,000. So for a professional whose defensible salary is already north of $184,500, the marginal value of shifting another dollar into distributions is about 2.9 percent, not 15.3 percent. The election still helps, but the argument for shaving the salary largely disappears, and with it most of the reason to take the risk. Model the actual gap in the savings calculator and check the wider position in the LLC tax guide.
What a defensible file looks like in practice: a one-page memo naming the roles you perform, the hours behind each, the wage data you priced them against, the number you landed on and the date you set it. Keep the source pages. Refresh it in the same week you sign the return, and keep the superseded versions, because the question an examiner asks is what you knew when you set the number, not what you can argue now. Payroll itself has to actually run: registrations, deposits and quarterly returns, which is the payroll setup, and the reporting map is in the 941 and 940 guide.
The Penalty Stack, in Dollars
The abstract version of reclassification is unpersuasive because it sounds procedural. Here is what actually gets assessed, in the order it arrives.
| Component | How it is computed | On $137,000 of reclassified wages |
|---|---|---|
| Social Security | 12.4% up to the $184,500 wage base, less wages already reported | About $19,406 |
| Medicare | 2.9% with no ceiling | About $3,973 |
| Failure to file Forms 941 | 5% of the tax a month, capped at 25% | Up to $5,845 |
| Failure to deposit | 2% to 15% depending on how late each deposit was | Up to $3,507 |
| Interest | From each original due date, not from assessment | Runs for as long as it took to find |
| One year only. The IRS ordinarily examines three, and the same computation repeats in each. | ||
The failure to deposit tiers are worth knowing precisely, because they are the ones people assume are small: 2 percent for a deposit 1 to 5 calendar days late, 5 percent for 6 to 15 days, 10 percent beyond 15 days, and 15 percent once the IRS has issued a notice and been ignored for 10 days. They do not stack; the highest applicable tier applies.
Above all of it sits the trust fund recovery penalty. Withheld income tax and the employee half of FICA are held in trust for the government, and a person who is responsible for paying them over and wilfully does not can be assessed personally in an amount equal to the entire unpaid trust fund balance. That assessment survives the corporation. It is the reason the phrase we would rather owe the bank than the payroll account is standard advice among people who have seen this go wrong.
Three Salaries, Three Defenses
Three S-corps with similar profit and three completely different right answers, because the source of the profit is different in each.
Example 1 - almost all of it is the owner's hands
Thornbury Orthodontics PLLC nets $420,000. One orthodontist performs every clinical procedure; four staff handle scheduling, hygiene support and billing. Practically all profit traces to the owner's licensed labour, so a token salary is indefensible. Regional wage data prices an employed orthodontist at $300,000 to $320,000, and the memo sets $310,000. Note what happens above $184,500: Social Security has already capped, so the $110,000 of distributions saves only the 2.9 percent Medicare component plus the 0.9 percent surtax.
Outcome: When the defensible salary is already above the wage base, shaving it buys very little and risks a great deal. Set it at market and stop optimising.
Example 2 - the profit comes from the system, not the owner
Saltmarsh Freight Brokers LLC nets $260,000 with six employees booking loads on carrier contracts the owner negotiated years ago. He works full-time as a general manager, not as a broker. Market data for a freight brokerage general manager in the metro is $95,000 to $115,000, and the memo sets $105,000. Without the election, self-employment tax on the whole $260,000 would run to roughly $30,200 once the wage base cap and the additional Medicare tax are applied. Employment tax on a $105,000 salary is $16,065.
Outcome: Capital, contracts and staff genuinely generate part of this profit, which is what makes a manager's salary the right comparison. The memo has to say that, with the wage data attached.
Example 3 - the token salary that got reset
Ivywell Software Group Inc reported $28,000 of wages to its sole shareholder-developer and $310,000 of distributions, on the reasoning that a forum post described 30 percent as safe. Every line of revenue traced to the shareholder's own development work. On examination the IRS set reasonable compensation at $165,000 and reclassified $137,000. Employment tax alone for that single year came to about $23,379, before the Forms 941 penalties, the deposit penalties and interest running from each original due date.
Outcome: The three-year exposure was the number that mattered, and no part of it was reduced by the argument that the salary had been chosen in good faith. Data and a memo would have cost an afternoon.
The Salary Mistakes That Draw Audits
Mistake 01
Why it happensEvery salary dollar costs 15.3%, and the incentive does the reasoning.
ConsequenceThe classic reclassification pattern, with penalties designed for it.
PreventionMarket-rate salary first; distributions are what remains.
Mistake 02
Why it happens60/40 folklore feels like a rule.
ConsequenceA number with no defense: ratios impress no auditor.
PreventionComparable wage data for your actual duties, filed in the memo.
Mistake 03
Why it happensThe owner keeps taking draws like before the election.
ConsequenceZero-wage S-corps with distributions are the easiest audit selection there is.
PreventionPayroll starts the quarter the election takes effect: see the setup guide.
Mistake 04
Why it happensThe number was defensible in year one and profit tripled since.
ConsequenceA salary reasonable for a $120K business looks token under $500K of profit.
PreventionAnnual review alongside the tax return, memo updated.
Pay yourself like a hire, keep the memo, enjoy the savings
The election's savings live entirely in the gap above a market-rate salary. Price your actual job with real data, run it through payroll, document the reasoning annually, and the S-corp does exactly what it promised without inviting the audit that undoes it.
Frequently asked questions
What is a reasonable salary for an S-corp owner?
What comparable businesses would pay someone else to do your job: the market rate for your actual duties, hours, and expertise in your area. There is no IRS percentage or chart. Owners doing full-time skilled work in profitable companies should expect a salary resembling a market hire, with distributions above that.
Is the 60/40 rule real?
No. The 60/40 split (60% salary, 40% distributions) is internet folklore with no basis in the tax code or IRS guidance. The standard is reasonable compensation for services, which might be 30% of profit for a capital-heavy business or 90% for a personal-services practice. Ratios are outcomes, not methods.
What happens if my S-corp salary is too low?
The IRS can reclassify distributions as wages, assessing back payroll taxes on the difference plus penalties (up to 100% of the tax in willful cases) and interest. Courts side with the IRS routinely when owners take large distributions on token salaries. The savings from an indefensible salary are borrowed, not earned.
How do I document a reasonable salary?
Keep a one-page file: your duties and hours, comparable wage data (BLS occupational data, industry surveys, job-board ranges for your role and region), the number you chose and why, reviewed annually as profit and duties change. Contemporaneous documentation converts an audit argument into a records request.
Can I take a low salary in a bad year?
Yes, legitimately. Reasonable compensation reflects what the business can and should pay for services: a loss year or cash crunch supports a reduced or paused salary, documented as such. What fails is the profitable company paying token wages while distributing heavily. Salary should track the business's reality in both directions.
Do S-corp distributions avoid all taxes?
No, only self-employment/payroll taxes. Distributions still face income tax on your return; salary faces income tax plus 15.3% FICA. The election's entire savings is the FICA gap between a reasonable salary and total profit, which is why the salary number is the whole game. Math: savings calculator.
Does reasonable salary apply to LLCs?
Only to LLCs that elected S-corp taxation. A default LLC has no salary requirement: members take draws, and everything is subject to self-employment tax through quarterly estimates. The requirement arrives with the election that creates the savings. See the LLC tax guide.
