How Often Should You Update a Reasonable Compensation Study?

A Study finished two years ago still looks current. Same figures, same citations, same sign-off date nobody rereads. Whether the shareholder's job still matches it is a separate question, and the file can't answer it on its own.

That's the problem with refresh timing. Most firms don't decide it. They inherit it from whoever prepared the return last year, so one preparer re-runs every client annually and another rolls the same figure forward until something breaks. For a tax partner running a recurring S-corp book, that inconsistency is the real exposure: two clients with the same facts, handled two different ways, and no record of why.

This piece covers when to update a reasonable compensation study and which events should force a full re-run. It ends with year two, when you carry last year forward instead of starting over. If you need the basics first, what a Reasonable Compensation Study contains has its own walk-through.

Why no rule tells you how often

Start with what the authorities actually test. IRC §162(a)(1) allows a deduction for a reasonable allowance for compensation for personal services actually rendered. Treas. Reg. §1.162-7(b)(3) frames reasonableness around what would ordinarily be paid for like services by like enterprises under like circumstances, and it looks at the circumstances existing when the contract for services was made, not when the pay is later questioned. That puts weight on a record made at the time: what the shareholder's duties, hours and pay arrangement were when the figure was set. Neither authority says a determination, once made, holds for any set number of years.

The employment-tax side points the same way. A corporate officer is an employee under IRC §3121(d)(1), and Rev. Rul. 74-44 treated amounts paid to shareholders who performed services as wages, whatever the corporation called them. The IRS repeats the point in Fact Sheet FS-2008-25. The question comes back every year the shareholder works and takes money out.

The case law is year-specific too. In David E. Watson, P.C. v. United States, 668 F.3d 1008 (8th Cir. 2012), the court looked at what the shareholder did and was paid in the years at issue. For a fuller tour of the guidance, see the IRS reasonable compensation guidance explained.

So the working conclusion is simple. A Study speaks for the year it was built on. Using it for a later year is a judgment that nothing material changed, and that judgment needs its own record. Not tax advice.

The annual review: what to check every year

Treat this as practice judgment, not a requirement from any authority. Once per tax year, for each shareholder-employee, before the officer compensation figure goes on the return, the preparer answers four questions:

• Did duties or hours move? Ask the shareholder directly and record the answer with the date. "Same as last year" is an answer, but it should be the shareholder's, not the preparer's assumption.
• Is the wage evidence still current? Check whether a newer edition of the source you cited has been released since the Study was finalized.
• Does payroll match the concluded figure? Compare W-2 wages to the figure the Study concluded. Payroll requirements for S-corp owners covers the mechanics on that side.
• Did anyone ask about it? A client question, a notice, or an examiner's inquiry about a prior year belongs in this year's file.

The review ends one of two ways. Either nothing material moved, the prior figure carries forward, and the Reviewer signs off on that conclusion. Or a trigger hit, and the Study gets re-run. Both outcomes leave a dated record. That's the part most firms skip, and it's the part that answers "why didn't this change?" years later.

Trigger events that call for a re-run

These are the events that change an input the figure depends on. None comes with a threshold in the listed authorities, so the Firm sets its own definition of "material" and applies it the same way across preparers.

Duties or hours change. The shareholder takes on sales, steps back from production, or cuts to part-time. The duty and time allocation drives the occupation mapping, so the whole computation moves with it.

Ownership changes. A new shareholder joins, one leaves, or percentages shift. Each shareholder who performs services needs their own determination, and a buyout often changes who does what.

A big swing in profit or distributions. Low wages next to large distributions is the pattern at issue in Rev. Rul. 74-44 and Watson. The Study doesn't have to track profit, but the file should show someone looked. S-corp salary vs. distribution covers that split.

A new location or service line. Geography and occupation are both inputs. A second office in a different metro area, or a new service the shareholder personally delivers, can change which wage evidence applies.

New wage data. When the source behind your wage evidence publishes a new release, the Study's citation now points at a superseded edition. Update the evidence and record its version and pull date. Using BLS OEWS wage data for reasonable compensation explains how to cite a release so a later reader can pull the same number.

A question from an examiner or the client. If anyone asked about a prior year's figure, re-run the current year with that question in view, and keep the answer you gave in the file.

Year two: roll the Study forward, don't rebuild it

A re-run doesn't mean starting from a blank interview. The efficient year two is a change analysis, and it follows four steps:

1. Carry forward last year's facts: duties, hours, occupation mapping, geography, and the reasoning behind each.
2. Confirm what changed with the shareholder, and record what didn't.
3. Update the wage evidence to the current edition, with its version and date.
4. Have the Reviewer sign the delta: what moved, why, and what it did to the figure.

The method doesn't need to change either. The IRS "Reasonable Compensation Job Aid for IRS Valuation Professionals" (2014) describes cost, market, and income approaches. If the Firm used one last year and the facts haven't shifted, keeping the same approach keeps the years comparable. Switching approaches is itself a change the Reviewer should see and sign.

In TracePrep, this is how the second year works: prior-year facts clone forward, the preparer confirms or edits them, and the Reviewer signs off on the changes with each figure traced to its source. Annual continuity shows the roll-forward, and Reviewer sign-off shows what the Reviewer sees before signing.

What stays with the Firm between refreshes

Each year's Study is its own record. The run of years is what explains the current number: this is what we concluded, this is what changed, this is who signed. A report that stands alone shows one conclusion. A connected series shows the reasoning moving with the facts.

That only works if the earlier years are still there. With TracePrep, the Firm permanently owns finalized evidence and workpapers; finalized Studies stay downloadable in TracePrep for three years after cancellation. For what goes in each year's file, see the workpapers a reasonable compensation file should hold. For why the record matters once someone starts asking, see reasonable compensation audit defense.

Conclusion

Review every Study once a tax year. Re-run it when a trigger event hits. Have the Reviewer sign each year's conclusion, including "no change." Run the same process for every client and every preparer, and the Firm can answer for any year from its own file. The S-corp reasonable compensation standard covers the full cluster.

Not tax advice.

These are the refresh questions firms ask most about a reasonable compensation study update.
