What a Reasonable Compensation Study Is

# What a Reasonable Compensation Study Is (and What Belongs in One)

Every other number on an S-corp return points somewhere. Depreciation points to a fixed asset schedule. Interest points to a lender statement. Officer compensation points to a conversation somebody had in February, written down if anyone thought to write it down.

That gap is the whole problem. S-corp reasonable compensation is a facts-and-circumstances standard with no safe-harbor percentage, so the figure is a judgment call, and the judgment belongs to a person rather than a formula. A Reasonable Compensation Study is the workpaper that makes that judgment legible: what the shareholder-employee actually does, what that work pays in their market, how the number was built, who built it, and who approved it.

Most firms already produce something shaped like this. It lives in a spreadsheet, a memo, and a preparer's memory, and it gets rebuilt from scratch each year by whoever happens to have the file. A Study is that same work, structured so it survives review, a staffing change, and a request for support three years after filing.

What is a reasonable compensation study? >A reasonable compensation study is a documented analysis supporting the salary an S-corporation pays a shareholder-employee who performs services. It has five parts: a structured intake of the shareholder's roles, duties, and hours; wage evidence drawn from cited sources and matched to occupation, geography, and period; a calculation that turns those inputs into a figure by a stated method; a Reviewer's sign-off on the conclusion; and a finalized deliverable retained as a workpaper. The point is traceability. Every material figure ties back to where it came from, and the reasoning behind any adjustment sits on the record instead of in someone's head. A study does not guarantee an IRS outcome. It gives the Firm a defensible, contemporaneous basis for the number it signed.

Key Takeaways

Five parts, in sequence - Intake, evidence, calculation, Reviewer sign-off, retained deliverable. Skip one and the remaining four get weaker.
Traceability is field-level, not document-level - Every figure ties to a source, an occupation, a geography, and a period, not to a bibliography at the end.
The Reviewer concludes - Software assembles evidence and applies a stated method. A person owns the number and signs it.
Contemporaneous beats reconstructed - Evidence gathered while the facts were fresh carries weight that a memo written after a notice arrives does not.
The Firm should hold the finished file permanently - A retention duty runs for years. A vendor subscription runs month to month.
Year two costs a fraction of year one - Prior-year facts clone forward, and the work becomes change analysis rather than a rebuild.

What a Reasonable Compensation Study is

The deliverable, defined

A Study is a bounded set of workpapers with a single conclusion at the end of it. Five stages produce it.

Intake captures the shareholder-employee's actual roles: the hours, the duties inside each role, the licenses and experience that make those duties billable, and the parts of the business that would need hiring if this person stopped showing up. Evidence attaches wage data to each of those roles from cited sources, matched to the occupation, the geography, and the period the return covers. Calculation combines the roles and the wage evidence by a method that is written down rather than improvised. Review is where a designated person examines the inputs, the adjustments, and the conclusion, then signs. The deliverable packages all of it into something the Firm files with the return workpapers and keeps.

What separates a Study from a memo is that the conclusion is reproducible. Hand it to a colleague who has never seen the client and they can follow the reasoning from the shareholder's job description to the salary figure without asking anyone a question. That is a different artifact from the planning number a client gets when they estimate a reasonable salary on their own. That property is what makes it useful under exam, and it is why the details of how the number is determined matter as much as the number itself.

Who it is for

Three readers use the same file for different reasons.

The Preparer needs a method that turns an ambiguous standard into a documented figure faster than the spreadsheet-and-memo process it replaces, and in a form that clears review the first time. The Reviewer needs to trust the number before signing it: where each figure came from, what was adjusted and why, what changed since last year, all without rebuilding the analysis. The Firm owner needs the process to look the same across every preparer, and needs the finished workpapers to still be there when a client calls with a question about a return filed four years ago.

The shareholder-employee is a fourth reader, and the least technical one. They get a document that explains, in their own job's terms, why their salary is what it is. That conversation goes differently when the answer is a sourced analysis rather than a percentage someone picked, and it is usually where the questions about how salary and distributions split get asked.

What belongs in a defensible Study

Structured intake

Intake fails when it asks for a job title. Titles compress; the IRS factors do not. A shareholder who calls herself the owner may be spending a third of her week doing licensed professional work, a third selling, and a third on administration that a coordinator could do for a fraction of the rate. Those three components price separately, and a defensible figure reflects the mix.

Good intake asks for hours by function, the training and experience behind each function, what non-shareholder employees are paid for comparable work, and the timing and manner of any bonuses. Those are the factors an examiner works through. Collecting them in a fixed structure rather than an open-ended conversation is what makes two preparers in the same firm produce comparable files.

Versioned wage evidence

Wage data goes stale, and it gets revised. A figure pulled from a source last spring may not match what the same source publishes now, which is a problem if the support for a filed return has silently drifted underneath it.

Versioned evidence means the Study records the exact data as of the date it was pulled, along with the occupation code, the geography, the period, and the source. The number in the workpaper and the number the examiner can independently locate are the same number. Field-level citation, not a source list at the back.

Deterministic calculation

The calculation should produce the same output from the same inputs, every time, for every preparer. That sounds obvious until you watch three people in one firm each weight a multi-role shareholder a little differently and land on figures that differ by tens of thousands.

Deterministic does not mean rigid. Judgment enters through documented adjustments: a preparer decides the market data overstates this role in this market and dials it down, and the Study records the prior value, the new value, the rationale, the timestamp, and who made the change. The method stays stable. The judgment stays visible. Nothing moves without a reason on the record.

Reviewer sign-off

Review is the control that makes everything upstream mean something, and it is where the Firm's professional risk actually sits. A Reviewer signing a compensation figure they cannot trace is carrying exposure they did not choose.

Sign-off works when the Reviewer can see the whole chain in one place: the intake facts, every wage source with its as-of date, each adjustment with its rationale, and the change analysis against the prior year. They approve or they send it back. Once approved, the evidence manifest is immutable, which means the file an examiner sees later is the file the Reviewer actually signed, not a version someone touched afterward.

Why ownership matters

The retention duty vs the subscription

The report you paid for last year is gone the month you stop paying. Your retention duty is not.

That mismatch is structural in the subscription wage-report category. The analysis lives in a vendor's system, the Firm holds a PDF at best, and access to the underlying evidence ends when billing does. A Firm that switches tools, or gets acquired, or simply lets a seat lapse, discovers the gap at the worst possible time: when a client forwards a notice about a return filed three years ago and the support for the salary figure is somewhere the Firm can no longer reach.

Finalized evidence and workpapers should stay with the Firm regardless of subscription status. Not a summary PDF. The intake, the versioned wage evidence, the adjustments and their rationales, the manifest, the signed conclusion. That is what how a Study holds up under exam ultimately depends on, and it is not something a Firm should be renting.

Annual continuity

Reasonable comp is an annual determination for a client whose facts mostly hold steady year to year. Rebuilding the analysis from zero each spring is waste, and it introduces drift: the same client, the same duties, a different preparer, a materially different number.

Continuity means year two starts from year one. Prior-year facts clone forward, the shareholder confirms or corrects them, the wage evidence refreshes to the current period, and the work narrows to change analysis. What moved, by how much, and why. Year two costs a fraction of year one, and the year-over-year record itself becomes evidence: a consistent method applied across years reads very differently than three unconnected memos.

How TracePrep builds a Study

Interview. Evidence. Calculate. Review. Sign.

Run the shareholder interview in a structured intake. TracePrep structures the role decomposition, pulls versioned wage evidence, and ties every figure to source, occupation, geography, and period. The calculation applies a stated method and flags contradictory inputs before review reaches them. A Preparer adjusts a figure and TracePrep records the rationale, the prior value, the timestamp, and who made the change.

The Reviewer sees the full chain and signs. The evidence manifest is immutable from that point. The deliverable packages the intake, the evidence, the calculation, the adjustment log, and the signed conclusion into a workpaper that goes into the tax file.

TracePrep supports professional judgment. It does not replace it, and it does not conclude on the Firm's behalf.

What the Firm keeps

The finished Study belongs to the Firm permanently, including the evidence behind it. Next year the prior facts clone forward and the work becomes change analysis. Years later, a client's question or an examiner's request gets answered from evidence the Firm still holds, in the same form the Reviewer signed.

Every figure traces to a source, at field level, and your Reviewer signs off on the record. Get started.
