But if your business benefits from the Qualified Business Income (QBI) deduction and you’re not a specified service trade or business (SSTB), that old approach can now cost you real money and increase your audit risk at the same time.
Today, if you own an S‑Corp that generates solid profits and you benefit from QBI at all, your entire thought process around owner compensation needs to shift from “minimum salary” to “data‑driven, optimized salary.”
What QBI Actually Does
The QBI deduction (Internal Revenue Code section 199A) generally allows owners of pass‑through businesses, including S‑Corps, to deduct up to 20% of their qualified business income on their individual returns. For profitable S‑Corp owners, this can easily become one of the largest single deductions on the return in a good year.
If your business is not an SSTB (so you’re not in fields like law, accounting, health, consulting, etc.), the QBI deduction is subject to additional limitations once your income climbs over certain thresholds. One of the big ones is the W‑2 wage limitation, which essentially ties the size of your deduction to how much the business pays in wages and, in some cases, how much qualified property it holds. That means your own W‑2 salary from your S‑Corp is now a central part of the QBI calculation instead of being just a payroll‑tax afterthought.
Why “Pay Yourself as Little as Possible” Broke
Before section 199A existed, S‑Corp planning focused heavily on minimizing Medicare and Social Security taxes. The standard playbook was pay yourself a salary that’s “just high enough” to survive an IRS audit and treat everything else as a distribution. The incentive was to keep wages as low as possible as long as they could still be defended as reasonable.
QBI flipped that logic. At higher income levels, your 20% QBI deduction can be capped by the amount of W‑2 wages paid by the business. If your S‑Corp has significant profit but very low wages, the wage limitation can sharply reduce the amount of QBI you’re allowed to deduct. In other words, a salary that’s too low can actually shrink your deduction and leave tax savings on the table.
How Your Salary Drives QBI
For S‑Corp owners above the QBI income thresholds and in a non‑SSTB, the deduction is often limited by a formula based on W‑2 wages (and sometimes the combination of wages plus a percentage of qualified property). Practically, it means your W‑2 wages help set the ceiling on how much QBI you’re allowed to deduct once those limitations apply.
There’s a key tension here:
- Lower wages increase your S‑Corp profit, which increases the “raw” QBI pool.
- But if wages are too low, the wage limitation can cap the QBI deduction at a lower level, no matter how high your profit is.
So instead of a simple “lower is always better” rule for salary, you now have to find a “sweet spot” where wages are:
- High enough to be clearly reasonable and to support the QBI deduction under the wage limits.
- Not so high that you’re overpaying payroll taxes on dollars that don’t move the needle.
Example: Solo Owner at Around $120,000 Profit
Think about a solo owner of a small marketing agency that runs about $180,000 of revenue with $60,000 of expenses and roughly $120,000 of profit. Under the old playbook, they might try to keep W‑2 wages down around $40,000 and pull the rest as distributions in the name of “saving” payroll tax.
The problem is:
- $40,000 is likely below what a full‑time professional generating that level of revenue would be paid in the market.
- As their taxable income climbs into the QBI phase‑in range, that low wage number can cap the 20% deduction, even though the business is highly profitable.
When we run a reasonable compensation study, it shows an $80,000 salary is supportable based on duties, hours, and comparable pay, that becomes a much better planning anchor. We can set wages at $80,000, take $40,000 in distributions, clear the reasonable compensation bar, and set the owner up to actually use the full QBI deduction once the wage limitation kicks in instead of leaving it on the table.
Reasonable Compensation: Still Required, More Important
The IRS has always required S‑Corps to pay shareholder‑employees “reasonable compensation” for the services they provide before distributing profits. Reasonable compensation is essentially what a similar business would pay someone else to do the job you’re doing, considering your responsibilities, skills, time commitment, and the size and profitability of the company.
In audits and court cases, factors like training and experience, duties, time devoted to the business, what comparable employers pay, and the overall financial performance of the company all come into play. If an owner is taking large distributions and very low wages, that’s a classic red flag. The QBI deduction adds another dimension: now, a too‑low salary doesn’t just trigger reasonable compensation questions; it can also limit a deduction that could have been worth thousands of dollars.
Why Annual Compensation Studies Make Sense Now
Your business changes. Your role changes. Your industry changes. What was reasonable two or three years ago may be completely off today. If you’re doing the same job description and making the same salary on paper while revenue and profits have doubled, it’s only a matter of time before that disconnect becomes a problem.
Annual reasonable compensation studies make sense because they keep your salary aligned with reality:
- As your responsibilities shift from “doing the work” to “managing people and strategy,” your market value changes.
- As your business grows or shrinks, a static salary often stops reflecting what a third‑party employer would pay someone in your role.
- As your income moves in and out of the QBI wage‑limitation ranges, the “right” salary for tax planning purposes can move with it.
Here’s what that looks like on the ground.
Example: Growing Trades Business That Outgrew Its Old Salary
A few years ago, a trades‑business owner whose numbers jumped from roughly $500,000 of revenue and $150,000 of profit before owner pay up to $750,000 of revenue and about $275,000 of profit. In Year 1, a reasonable compensation study supported a $75,000 salary for the owner, with the remaining profit coming out as distributions.
By Year 3, the story had changed: the owner was managing a crew, bidding more complex jobs, and spending more time on sales and oversight than on the tools. When we reran the compensation study, the reasonable range had climbed into the $110,000–$130,000 band. Bumping salary to about $120,000 did three things at once:
- It aligned pay with the owner’s expanded responsibilities and with market data.
- It reduced the risk of the IRS questioning a low salary attached to a much larger profit.
- It created more wage “room” to support the QBI deduction once the owner’s taxable income entered the wage‑limited zone.
If salary had been left at $75,000 “because that’s what we picked a couple years ago,” both the reasonable compensation story and the QBI math would have been wrong for the current reality of the business.
Example: Low‑Profit Year Where the Study Still Matters
The flip side is a softer year. Suppose that same S‑Corp drops to $600,000 of revenue and only $120,000 of profit before owner pay. An updated compensation analysis might show a reasonable range of $100,000–$115,000 given the owner’s responsibilities and the market.
In that situation, setting salary at around $100,000 and taking a much smaller distribution keeps the owner comfortably inside a defensible range while acknowledging that it’s a leaner year. QBI might not be the star of the show in a year like this, but a current compensation study still keeps you out of trouble: you’re not overpaying yourself out of a thin profit, and you’re not slashing salary to a level that will look suspicious when an agent compares it to prior, more profitable years.
The New “Sweet Spot” Mindset
Planning now is less about “How low can we go?” and more about “Where is the sweet spot?” That sweet spot is where:
- Your salary is clearly reasonable and supported by data.
- Your W‑2 wages are high enough to fully support your QBI deduction once wage limits apply.
- You’re not paying more payroll tax than necessary on dollars that don’t give you any additional tax benefit.
For many S‑Corp owners, the process looks like this:
- Start with a formal, reasonable compensation study to determine a defensible range based on your actual duties, time, and industry benchmarks.
- Within that range, model different salary levels to see how they affect:
- Payroll taxes (Social Security and Medicare).
- The QBI deduction under the wage limitation rules.
- Your ability to fund retirement plans and other benefits that depend on W‑2 compensation.
This is especially obvious in multi‑owner S‑Corps where both the total wage pool and how it’s divided matter.
Example: Husband‑and‑Wife S‑Corp at $300,000 Profit
Picture a husband‑and‑wife team running a non‑SSTB S‑Corp doing $500,000 in revenue with $300,000 of profit before their own pay. Under the old approach, they might split $80,000 of wages ($40,000 each) and take the remaining $220,000 as distributions. On paper, which looks like a payroll‑tax win; in reality, the numbers often don’t hold up.
A fresh compensation study might show that one spouse’s CEO/rainmaker role supports $130,000–$150,000 and the other spouse’s operations/admin role supports $60,000–$80,000. When they realign their salaries to around $140,000 and $70,000, two important things happen:
- The total $210,000 of wages is much more in line with what two full‑time owners of a $500,000‑revenue business would make in the market.
- As their taxable income crosses into the QBI wage‑limitation range, that higher W‑2 base supports a much larger 20% deduction compared with the old $80,000 number.
That’s the new planning reality: at higher income levels, the “cheap salary” strategy doesn’t just create audit risk; it can literally cost you a five‑figure QBI deduction.
Why a Formal Report Beats a Guess
In an audit, “We just picked a number” is not a compelling explanation for your salary. A structured, reasonable compensation report that ties your pay to independent data—job duties, time allocation, industry benchmarks, and company size—is far more persuasive. It also gives you a clear, repeatable process: every year, you update your role, revenue, and business performance and then adjust your salary within a documented range.
In each of the examples above, the turning point wasn’t a clever spreadsheet trick—it was getting a real compensation number from an independent source and then building QBI planning around that number, not the other way around. Once you know what’s reasonable, you can make informed decisions about where to set your pay within that range, given your QBI situation, your retirement goals, and your cash flow.
Where Salary Sherpa Fits In
If you own an S‑Corp and your compensation hasn’t been reviewed in the last year, you’re essentially flying blind in a QBI world. Your QBI deduction, your audit profile, and your retirement planning all depend on numbers that may be years out of date.
That’s why I built a dedicated, reasonable compensation platform like Salary Sherpa. It provides structured, data‑driven, reasonable compensation reports built specifically for S‑Corp owners and their advisors. With Salary Sherpa, you can:
- Anchor your salary to defensible market data instead of guesswork.
- Revisit and update your compensation annually as your responsibilities and profitability change.
- Give yourself and your tax advisor a solid foundation for QBI planning, payroll tax strategy, and retirement design.
In a period where QBI is an important factor in your overall tax picture, reasonable compensation studies aren’t a “nice to have” anymore—they’re a core part of running your S‑Corp like a real business. Running that study every year is how you keep your salary both reasonable and strategically smart.
