S-CORP COMPENSATION PLANNING: THE NUMBERS YOUR SALARY DECISION ACTUALLY TOUCHES

WHY PAYING YOURSELF THE MINIMUM SALARY ISN'T THE FULL STRATEGY

When S-Corp owners talk about compensation planning, the conversation usually starts and ends in the same place: pay yourself as little as the IRS will accept.

That is a tax minimization instinct, and it is not wrong. The whole point of the S-Corp structure is that distributions (the profits passed through to you after salary) are not subject to FICA. FICA is the 15.3% tax that covers Social Security (12.4%, assessed on wages up to $184,500 in 2026) and Medicare (2.9%, no wage cap). Minimizing the salary minimizes the FICA bill. The math is straightforward.

But reasonable compensation is not a number. It is a range. And where you land in that range touches four variables that most owners never fully account for. Once you run all of them, the calculus changes.

WHAT THE IRS ACTUALLY REQUIRES

The IRS defines reasonable compensation as what a comparable business would pay someone with your skills to do your job. That is it. No formula. No safe-harbor percentage. No rule that 60% of profit equals a defensible salary. Courts have explicitly rejected that approach.

What the IRS evaluates instead is a facts-and-circumstances test: your training and experience, the duties you perform, how much time you spend in the business, what comparable employees in your industry earn, and the overall profitability of the company. Watson v. Commissioner, where a CPA paid himself $24,000 while taking over $200,000 in distributions, is the most-cited example of how badly that goes wrong. The IRS won. The distributions were reclassified as wages.

In practice, this creates a defensible range: a low end and a high end, both supportable by documentation. The low end reflects the minimum salary the market would accept for your role. The high end reflects the maximum compensation the business economics can justify. Both can be argued. Where you land within that range is a planning decision, not an arbitrary one.

The conventional approach is to land closer to the low end. That minimizes FICA, which at 15.3% represents real money. Once you have established a defensible low-end salary, everything above it comes out as distributions, free from employment tax.

That is the right starting framework. But it is only the beginning.

WHETHER YOUR HEALTH INSURANCE DEDUCTION SURVIVES

If the S-Corp pays your health insurance premiums, or reimburses you for premiums you pay personally, those amounts need to appear on your W-2. Specifically in Box 1 (taxable wages for federal income tax purposes), but not in Box 3 or Box 5, which govern FICA. The premiums are excluded from payroll taxes. They typically appear in Box 14 as an informational note.

Why does the reporting path matter? Because the above-the-line deduction under IRC §162(l), which takes those premiums off your adjusted gross income without requiring you to itemize, is only available if the S-Corp paid or reimbursed the cost and reported the amount on your W-2. If your spouse's employer offers subsidized coverage, the deduction is blocked for any month you are eligible for that plan.

Here is the part that catches people: the deduction is also capped at your earned income from the S-Corp, which is your W-2. If your family health insurance runs $22,000 a year and you pay yourself $18,000, the deduction is limited to $18,000. You left $4,000 on the table. Not because of a compliance error. Because your salary set a floor beneath the deduction.

Setting your salary with this in mind means knowing your annual health premiums before you finalize the W-2.

HOW MUCH RETIREMENT YOU CAN ACTUALLY CONTRIBUTE

Retirement contributions through an S-Corp are calculated as a percentage of W-2 compensation. This is where salary planning gets precise.

In 2026, the §415(c) limit (the total annual additions limit combining employee deferrals and employer profit-sharing) is $72,000. The elective deferral limit under §402(g) is $24,500. The employer profit-sharing contribution for an S-Corp shareholder-employee is 25% of W-2 wages.

Work that backward. If your target is the full $72,000: the employee deferral accounts for $24,500. The remaining $47,500 has to come from profit-sharing. At 25%, generating $47,500 requires $190,000 in W-2 wages. That is the minimum salary to reach the statutory maximum with a full elective deferral.

If you pay yourself $120,000 instead, the math is: $24,500 in employee deferrals plus $30,000 in profit-sharing, for a total of $54,500. That is $17,500 less than the statutory maximum. Not because of any rule violation. Because the salary set a ceiling on the contribution.

And if you’re using a SEP IRA, the math is even worse ($72,000 / 25% = $288,000 W-2 needed for the maximum contribution)!

Owners who want to maximize tax-deferred retirement savings need to back into the required salary, not set the salary first and accept whatever retirement room is left.

HOW YOUR SALARY INTERACTS WITH THE §199A DEDUCTION

The §199A qualified business income (QBI) deduction was made permanent by the One Big Beautiful Bill Act, signed in July 2025. It allows pass-through owners to deduct up to 20% of their qualified business income. For 2026, the deduction begins to phase out at $403,500 of taxable income for married filing jointly filers, and $201,750 for single filers.

The first thing to understand is that your W-2 wages are excluded from QBI. Qualified business income is the S-Corp's net pass-through income, not your salary. A higher salary reduces the S-Corp's taxable income (wages are deductible by the corporation), which reduces the QBI flowing to your return.

Below the threshold, that interaction is largely academic. You get the full 20% deduction regardless of salary level, so a shift between salary and distributions does not change the outcome. This is where most S-Corp owners live.

Above the threshold, it matters, and it plays out differently depending on your business type.

For owners of specified service trades or businesses (SSTBs), including law firms, medical practices, accounting firms, consulting businesses, financial services, and any business whose principal asset is the reputation or skill of its owners, the §199A deduction phases out completely by $553,500 MFJ in 2026. Once you are above that threshold, there is no deduction and no wage-based workaround. The salary optimization does not help here.

For non-SSTB owners above the threshold (manufacturing, retail, construction, technology, most real estate operations), the deduction does not disappear. It converts to a wage test. The deduction is capped at the greater of (a) 50% of W-2 wages paid by the business, or (b) 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property. This is where a counterintuitive result emerges: above the threshold, a higher W-2 can expand the available deduction.

A manufacturing S-Corp owner at $600,000 of taxable income with $200,000 in W-2 wages has a deduction ceiling of $100,000 (50% x $200,000). Raise the salary to $250,000 (more FICA, yes) and the ceiling rises to $125,000. Whether the math favors the higher salary depends on the incremental FICA cost versus the value of the preserved deduction. You cannot answer that without modeling it. 

For SSTB owners below the phase-out range, the deduction works exactly like everyone else's: 20% of QBI, no wage test. A law firm owner at $350,000 of MFJ taxable income gets the full deduction. The SSTB restrictions only bite at high incomes.

HOW THE FOUR VARIABLES WORK TOGETHER

Every S-Corp owner doing compensation planning is managing four variables at the same time.

• One: FICA exposure. The core reason you elected S-Corp status. Minimize where the defensible range allows.

• Two: health insurance deduction. Your W-2 must be at or above your annual premium cost to capture the full §162(l) deduction. Know the number before you set the salary.

• Three: retirement contributions. The 25% profit-sharing calculation means the salary is the lever. If the $72,000 maximum matters to you, the salary has to support it. That means $190,000 minimum.

• Four: §199A. Below the thresholds, this is not a constraint. Above them, it is either a non-issue for SSTBs or a W-2 optimization problem for non-SSTBs.

None of these work independently. The salary that minimizes FICA may undercut your health deduction. The salary that maximizes your retirement contribution may reduce your QBI base. The salary that preserves your §199A might not be worth the incremental FICA cost. You have to run the full model.

This is not a year-end conversation. It is a structure decision you make before the distributions start.

Every situation is different. This is not tax advice for yours. Book a call if you want to look at your specific numbers.

FREQUENTLY ASKED QUESTIONS

What counts as reasonable compensation for an S-Corp owner in 2026? 

Reasonable compensation is the amount a comparable business would pay someone with your experience and credentials to do your job — there is no fixed formula or safe-harbor percentage. The IRS evaluates factors including your duties and responsibilities, hours worked, industry pay benchmarks, and your company's profitability. The practical result is a defensible range: a low end you can document and a high end the business economics support. Every situation is different, so confirm with your advisor before acting.

Do I have to include health insurance premiums on my W-2 to deduct them?

Yes, for S-Corp owners who hold more than 2% of the company. Premiums paid or reimbursed by the S-Corp must be included in Box 1 of the W-2 (wages for income tax), but excluded from Box 3 and Box 5, so no FICA applies to the premium amount. Once reported correctly, you deduct the premiums on Schedule 1 of Form 1040 under IRC §162(l) via Form 7206. The deduction is capped at your W-2 wages from the S-Corp, and is disallowed for months in which you or your spouse were eligible for a subsidized employer plan elsewhere.

How much W-2 salary do I need to maximize a 401(k) with profit sharing in 2026?

You need $190,000 in W-2 wages to maximize a 401(k) with profit sharing in 2026. The 2026 §415(c) total contribution limit is $72,000, of which $24,500 can come from your employee elective deferral under §402(g). The remaining $47,500 has to come from employer profit-sharing, capped at 25% of W-2 wages — which is why it takes $190,000 in salary to get there. A lower salary caps the total contribution proportionally.

Does my S-Corp salary affect the §199A QBI deduction?

Yes, in two ways. First, W-2 wages are excluded from qualified business income, so a higher salary reduces the QBI base. Second, if your taxable income exceeds the 2026 threshold ($403,500 MFJ), your QBI deduction for a non-SSTB is limited to the greater of 50% of W-2 wages or 25% of W-2 wages plus 2.5% of qualified property. Above the threshold, a higher salary can expand that limitation and preserve more of the deduction. 

Is the §199A deduction available to law firms, medical practices, or consulting businesses?

Below the income threshold, yes. SSTB owners get the full 20% deduction just like any other pass-through owner. Above the threshold, the deduction phases out completely and is fully eliminated by $553,500 MFJ in 2026. Architects and engineers are explicitly carved out of SSTB classification and are treated like any other qualified trade or business at all income levels.
