S-Corp Reasonable Salary Calculator

Every S-corp shareholder-employee who performs services has to take a reasonable salary before taking distributions. The standard is facts-and-circumstances. There is no percentage that makes it safe, no formula the IRS blesses, and no shortcut that holds up in a real examination. Which leaves a lot of owners doing the one thing the standard does not reward: guessing.

A starting number helps. The reasonable compensation calculator takes five inputs and returns an estimated reasonable-compensation range anchored to published wage data for the role and state you select. Once the range is ready, a second panel shows what the low, mid, and high salaries in it do: payroll tax, cash left to distribute, and an estimated section 199A deduction. Enter a work email and you get the full report: a factor-by-factor breakdown, a salary-vs-distribution scenario, and how a Study would defend each factor.

Read the next sentence before you use it. That range is an estimate for planning. It is not a determination, and it is not evidence. Anyone telling you a calculator output settles the question is selling a number, not a defense.

So how do you calculate a reasonable salary for an S-corp? Start by describing what the shareholder-employee actually does: the roles they fill, the hours behind each one, the market that pays for that work. Tie each piece to published wage data for the right occupation, geography, and period, then adjust for the facts a wage table cannot see, including company size, profitability, the value of non-shareholder labor, and the owner's experience. A calculator can approximate the first half. The second half is professional judgment, and it is where the number becomes defensible. Treat any calculator result as a planning range to bring to your tax professional, not a conclusion. Reasonable compensation is a facts-and-circumstances determination, and the figure that survives review is the one with traced evidence behind it.

Estimate a starting reasonable salary

Five inputs. Role and state do most of the work, because published wage data is organized by occupation and geography, and those two dimensions move a wage figure further than anything else you could type into a form. Two choices widen the anchor: "Other / multiple roles" uses a band across occupations, and "Multiple states" uses a national baseline, so neither carries a role-specific or state-specific citation.

The tool returns a range rather than a single number. That is the honest shape of the answer. Wage data describes a distribution across many workers, and a specific shareholder-employee sits somewhere inside it based on facts the form never asked about. A range keeps that uncertainty visible instead of hiding it behind a decimal point.

What the estimate means

It means: given what people in this role are paid in this state, here is the band a salary would plausibly land in.

It does not mean the IRS would accept the midpoint. It does not mean a lower figure is wrong or a higher one is safe. It is a planning anchor, useful for a distribution conversation in the third quarter, useful for a payroll decision you can still adjust, useful for knowing whether the current salary is roughly in the neighborhood or nowhere near it.

Owners come to a tool like this in one of two states: setting a salary for the first time with no reference point, or suspecting the number their return has been carrying is low and wanting to know how low. The estimate answers both well enough to act on. It answers neither well enough to defend.

Read the "What this salary does" panel

Once the range is ready, the calculator adds a panel headed "What this salary does." It takes the low, mid, and high points of the range and shows three figures for each one. The panel is written for the tax professional advising the owner, so its labels say "your client." Owners can read it the same way.

What each column shows

Payroll tax (employer + employee). Both shares of Social Security and Medicare on that salary. Social Security stops at the 2026 wage base of $184,500 (SSA). Additional Medicare is counted at the employer withholding trigger, so your client's final liability can differ with filing status and other wages.

Cash left to distribute. Net income, less the salary, less the employer share of payroll tax. It is arithmetic on the net-income figure you entered. When the salary plus the employer share runs above net income, the column shows $0 and a line says there is nothing left to distribute.

Estimated section 199A deduction. Shows "Choose filing status and SSTB" until you pick your client's filing status and answer whether the business is a specified service trade or business (SSTB). Those two answers belong to the panel only. The five-input range does not change when you set them.

Every figure in the panel is rounded to the nearest $100.

How the section 199A estimate is built

The panel treats the salary as what it is: reasonable compensation, which is not qualified business income. So QBI is the same figure as cash left to distribute, net income less the salary and the employer payroll tax. The estimate starts at 20% of that QBI, after any SSTB reduction described below.

Taxable income is approximated as salary plus QBI, because the calculator never asks about other income or deductions. That proxy decides which rules apply, using the 2026 figures from Rev. Proc. 2025-32:

• Below the threshold ($201,750 for single and head of household; $201,775 for married filing separately; $403,500 for married filing jointly), the W-2 wage limit does not apply.
• Inside the phase-in range (up to $276,750, $276,775, and $553,500 in the same order), the wage limit partly applies, and an SSTB's deduction phases down across the same range.
• At or above the end of the range, the wage limit fully applies, and an SSTB gets no deduction.
• When QBI, after any SSTB reduction, is at least $1,000, the deduction is at least $400.

This is why the three columns do not always move together. Below the threshold, a higher salary tends to lower the estimate because it shrinks QBI. The $400 minimum and the $100 rounding can leave it unchanged. Above it, the salary also sets the wage limit, since the only W-2 wages the panel counts are your client's. There a higher salary can raise the estimate or lower it. For the full mechanics, see how salary and section 199A interact for S-corp clients.

What the panel leaves out

The panel prints its own assumptions under the columns. Read them before you quote a figure:

• Taxable income is salary plus QBI from this business. Other income and deductions move the threshold test.
• W-2 wages are your client's salary only. Wages paid to other employees raise the wage limit.
• The overall cap tied to taxable income less net capital gain is not computed.
• One owner with 100% ownership who materially participates, and no qualified property (UBIA).
• Other deductions tied to the business, such as 2% shareholder health insurance and retirement contributions, also reduce QBI. They are not included.

The panel labels itself "An illustrative estimate, not tax advice." Take it at its word. Use it as a first read on consequences, and build the return from the real figures.

What the panel does not do

It does not pick a salary. The panel does not rank or recommend the three salary points, and it does not compare them against the salary your client pays today. That is deliberate. The reasonable compensation standard asks what the services are worth, not which salary the deduction prefers.

What the panel gives you is one page for the client conversation: the range, and what each point in it costs in payroll tax, leaves for distribution, and does to the deduction. The number itself still has to come from the facts. The panel closes on the same point this article does: "A calculator gives a range; a Study documents the number and your Reviewer signs off." For the split itself, see S-corp salary vs. distribution.

Why an estimate is only the start

What a calculator cannot see

A wage table knows what a job title pays. It does not know your business.

It does not know that the owner ran operations for nine months and then hired a manager. It does not know that the roles shifted mid-year, what the non-shareholder employees earn, how bonuses were timed, or whether distributions have been running years ahead of salary.

Those are the facts the IRS factors turn on: dividend history, payments to non-shareholder employees, and what comparable businesses pay for similar services, among others. The full factor list sits under S-corp reasonable compensation.

A five-input estimate touches three of those. That is the boundary of what any input form can reach, and it is why how the number is really determined starts with an interview instead of a form.

From estimate to defensible Study

Here is the part owners tend to discover late. Under examination, nobody asks what the calculator said. They ask where the number came from.

That question has a good answer only when the number was built on evidence. Every figure tied to a source, an occupation, a geography, and a period, at field level. Every Preparer adjustment recorded with its rationale, the prior value, the timestamp, and who made the change. An immutable evidence manifest showing who prepared the work, what moved, and who approved it.

That package is a Reasonable Compensation Study, and it is the difference between a defensible position and a plausible one. For the anatomy of it, see what a full Study adds.

The Reviewer concludes on that evidence. Not on a calculator output. Keeping those two things separate is the entire reason the evidence exists.

Retention matters here too. The document-retention duty behind a filed return runs on its own schedule, so the evidence behind the salary has to outlast any one subscription.

Take it further

Owners: take the range and the inputs behind it to the person who signs your return. The useful conversation is not "is this number right." It is "here is what I do in the business, here is the time it takes, here is what I pay everyone else, what does that support?" Ten minutes of that beats anything a form can produce. Your preparer gets the facts without an email chain, and you get a figure that reflects your year instead of your job title. If your firm already runs Studies, ask for one. If they do not, ask what documentation stands behind the salary on your return.

Firms: you already know the estimate is not the deliverable. The work is the interview, the evidence, the documented judgment, and the sign-off, done consistently enough that every Preparer hands the same Reviewer something they can approve. That is what TracePrep does. Run the shareholder interview. The platform pulls versioned wage evidence, ties every figure to source, occupation, geography, and period, and records each adjustment with the reason behind it. The Reviewer signs. The evidence manifest is immutable. The Firm permanently owns finalized evidence and workpapers. Finalized Studies remain downloadable in TracePrep for three years from the date the subscription ends, for any reason.

Run the reasonable compensation calculator with a client, or send them to it, when they want a planning number this week. Build the Study when the number has to hold. Every figure traces to a source, and your Reviewer signs off on the record. Get started.
