Quick Answer
Build a dated file before you pay yourself. It holds your duties and weekly hours, saved wage data for comparable roles in your metro, the specific salary you chose and why, and a signed approval, all backed by matching payroll records. Then refresh it every year, because the tax law never spells out a reasonable salary for you.
An owner goes over salary records with an advisor, so every figure has documented support before an audit.
How do you document a reasonable S-corp salary for an audit?
You build one dated file before payroll starts: your duties and hours, named wage data for your metro, the number you chose and why, and a signed approval.
What you need:
- A one-page list of your duties, with weekly hours for each
- Wage tables from named sources, such as BLS Occupational Employment and Wage Statistics for your metro area, saved as screenshots or PDFs
- Last year's W-2, Forms 941 and distribution records
- Current financial statements
- A one-page compensation memo and a board resolution or written consent
- Write down what you actually do. Split your week by duty: selling, delivering the work, managing, admin. In SDO CPA's example, a 50-hour week spread across engineering, sales, management and admin is four different wage lookups.
- Pull wage data for each duty in your own metro. SDO CPA built its 2026 owner ranges from the May 2025 BLS release plus industry surveys, and it puts the warning plainly: "A national median is the wrong number for almost everyone." Record the occupation, geography, data period and percentile you used.
- Pick one number and write down why. Land on a specific salary, then note what moved you inside the range: experience, hours, staff, and how much profit comes from your own labor. SDO CPA again: "A range is not a permission slip to take the bottom."
- Approve it in writing before you pay it. Sign a dated board resolution or consent. An agreement written after the IRS calls carries little weight.
- Run it through payroll on a steady schedule. Withholding, a W-2 and quarterly Forms 941 turn your decision into a record.
- Save the sources, not just the links. Keep copies of the salary stats you used. Websites change. Saved files don't.
- Reprice every year. Update the duties list, pull fresh wage tables, and reconcile salary, Forms 941, W-2s and distributions before you file.
The cost of skipping this shows up in Watson v. United States. SDO CPA reports the owner took a $24,000 salary; the court accepted a reasonable figure of $91,044 a year and recharacterized $67,044 of each reviewed year's distributions as wages, with employment taxes, penalties and interest attached. Records don't guarantee an outcome. They do mean you walk in with an answer instead of a shrug.
Common mistakes:
- Using a 60/40 split as your file. No IRS rule backs the ratio, so replace it with wage data tied to your duties.
- Writing the memo after an IRS letter. Date and sign your approval before the first paycheck of the year.
- Benchmarking a national job title. Price your actual duties in your own metro, and say in writing how you adjusted for part-time hours.
At Modern Wealth, tax and business advisory are two of our eight planning service areas, so I would rather build this file alongside your investment management plan and your business value gap numbers than hunt for it in April. Our Modern Wealth planning FAQ explains how that works. Your CPA still signs off on the number. I just keep it from becoming a terrible action movie.
Frequently asked questions about documenting an S-corp salary
Is a 60/40 split good enough if I write it down?
No. Max Donovan of what.tax has promoted a split of roughly 40% of net income as salary and 60% as distributions, but a ratio on paper is still a ratio. Your file needs wage data tied to your duties, because reasonable compensation means what an unrelated person would earn doing your work.
Does a complete file guarantee the IRS accepts my salary?
No. Records do not guarantee an outcome. They give the examiner your reasoning, your sources and your dates, so the discussion starts from evidence instead of a guess. If you want help building that file, Modern Wealth's contact page at modernwealthllc.com/contact-us is the place to start.
How often should I update the file?
Every year, before the first payroll of the new year. Update it sooner if your duties, hours, staff or profits change in a big way. A salary that never moves while everything else does is the part that draws questions.
