An HVAC company's S election, a $92,000 market rate, and a gap nobody had measured

The business in this guide is invented, written to show the arithmetic on one ordinary company's figures. It is not a customer, and nothing here is a testimonial. The figures are made up; the rates, the method and the tool's own output are not.

The moment

Brightline Heating & Air runs six vans out of a yard in Dayton, Ohio. The business elected S-corporation status three years ago, on an accountant's advice, mainly to save on self-employment tax. Nobody ever came back to the part of that decision that comes with an obligation attached.

The owner takes money out whenever the personal account gets low — a transfer here, a bigger one after a good month — and none of it runs through payroll, even though the eleven employees are all on it. It is year-end, and the new CPA doing the S-corp return asks a question the last one never did: what do you pay yourself, and can you show it.

The honest answer is "whatever the balance allows," which is not an answer an S corporation is allowed to give.

What they did instead

The plan, to the extent there was one, was a piece of advice repeated at every trade-association breakfast: take a small salary, take the rest as distributions, because distributions are not subject to self-employment tax and salary is. So the owner took the "small salary" part literally and skipped the salary altogether, on the theory that less payroll now meant less scrutiny later.

It is the opposite. The rule is not that a smaller salary is safer. The rule is that the salary has to be reasonable for the work actually done, and it has to exist before anything else is decided. Skipping it does not reduce the question — it just means nobody has answered it yet, on a return that has already been filed.

The cost of not knowing is not this year's return. It is that every year the pattern continues, the question gets bigger, and it gets asked by someone who was not in the room when the decision was made.

The questions a CFO asks first

  1. How is the business actually taxed? An S election is not itself the answer to what you owe yourself.
  2. Does any of what you take run through payroll?
  3. What would you pay someone else to do your job?
  4. What do you need each month to live — your floor, not a guess at fairness?
  5. What buffer do you want to keep, and what do you already hold?

Question 3 is the one most owners have never looked up. Question 1 is the one that changes what every other question even means.

The arithmetic, shown

Brightline's figures. The business nets $380,000 a year before the owner's own pay. The owner has been pulling about $150,000 a year out as transfers — none of it through payroll. Personal floor: $9,500 a month, $114,000 a year. Buffer target: 3 months at $58,000 of monthly outgoings, $174,000. Held today: $61,000.

Scenario one — the position as found.

Business net profit$380,000
Personal floor$114,000
Above the floor$266,000
Taken as wages$0
What the role pays elsewhere$92,000
Buffer target$174,000
Buffer held$61,000
Buffer still to build$113,000

The headline the tool gives back is blunt: taking money out of an S corporation without running it through payroll is the position the IRS examines most closely. The comp gap is not a shortfall in the business — the $266,000 of headroom shows the money is there — it is a fact about how none of it has been run through payroll at all. $0 taken as wages against $92,000 for the same job done by someone else is the gap the return has to answer for.

Scenario two — after the raise.

The owner sets a $100,000 salary and runs it through payroll, above the $92,000 the role would pay elsewhere.

Taken as wages: $100,000. Gap against market: -$8,000 — a negative gap, meaning the salary is now above what the role pays elsewhere rather than below it. The headline changes too: reasonable compensation is a requirement here, not a preference, and now there is a payroll record showing it was met rather than a return with no wages on it at all.

Scenario three — the entity nobody had checked.

Run the same numbers with "how is the business taxed" answered "I don't know," and the tool gives back nothing at all:

"Until you know how the business is taxed, there is no number here worth giving you."

Not a rough number, not a default assumption — no number, because a sole proprietor, a partnership, an S corporation and a C corporation are not asking the same question about owner pay, and a figure computed without knowing which one applies is not a rough version of the right answer. It is a precise answer to a different one.

What changed

Nothing about the business changed. The $380,000 the business nets before owner pay was always there.

What changed is that $100,000 of it now has a name — salary, on payroll, above what the role pays elsewhere — and the rest is distributions, which is what an S corporation's structure is actually for once the floor underneath it is met. The buffer target is now a number too: $174,000, three months of outgoings, with $113,000 still to build on top of the $61,000 already held.

What the tool will not do

It will not state a reasonable-compensation figure as a conclusion. The IRS publishes nine factors — training and experience, duties, time devoted, and six more — and no weighting between them. The tool reports the factors; it does not score them, and no tool should, because the authority itself declines to.

It will not compute self-employment tax. Net earnings from self-employment are a defined fraction of net profit, computed on Schedule SE, and this tool has not verified that fraction from the issuing source — so it names Schedule SE and stops rather than guessing at the base.

It will not split a mixed draw into its wage and distribution parts. If some of what you take runs through payroll and some does not, the tool needs to know the full amount actually paid through payroll — say "some payroll, some transfers" without separating the two and the wage side of the gap reads as zero, which is a true statement about what it was told, not a measurement of what you actually paid yourself in wages.

It does not know your state's rules, does not model your personal income tax, and — for a partnership — does not and cannot override what the partnership agreement already says about how money is shared.

It is arithmetic and a set of published rules applied to figures you supplied. Reasonable compensation itself is a judgment call for you and your CPA, made with the nine factors in front of you, not a number this tool hands you.

Owner Pay and Draw

What you can take out, by how the business is actually taxed — with your personal floor first and no reasonable-compensation number invented.
