S-Corp Salary: Why a $10,484 Payroll Tax Saving Shrinks to $7,032

The pitch for an S corporation election usually comes down to the self-employment tax you stop paying on profit you take as distributions. On $150,000 of profit with a $70,000 salary, that number is $10,484 for 2026.

Two things eat into it. The salary has to be one the IRS would accept as pay for the work you do, so you do not get to pick a small one. And the qualified business income deduction shrinks when part of your profit turns into wages, which hands back about a third of the saving before you have paid for payroll or a second tax return.

The election is still worth making for a lot of owner-operators.

1. Where the saving comes from

A sole proprietor or single-member LLC pays self-employment tax on 92.35% of net profit: 12.4% for Social Security up to the 2026 wage base of $184,500 ($192,300 for 2027), and 2.9% for Medicare on all of it. Half of that tax is deductible on your return.

An S corporation splits the same profit in two. The salary goes through payroll and carries 7.65% from you and 7.65% from the company, the same 15.3% in total. Whatever profit is left after the salary passes through on a K-1 and carries no Social Security or Medicare tax at all. The saving is the 15.3% you no longer pay on that second slice.

Above the wage base the arithmetic changes. A sole proprietor stops paying the 12.4% on earnings past $184,500 anyway, so for very profitable owners the election only saves the Medicare piece on the top dollars, about 2.7 cents per dollar of profit, or 3.5 cents once the additional 0.9% Medicare tax applies.

2. The worked example, to the dollar

A single filer runs a service business with $150,000 of net profit in 2026, no other income, and takes the $16,100 standard deduction. Federal tax only.

The payroll tax drops by $10,484. The income tax rises by $3,453. The owner keeps $7,032 (the three figures are rounded separately), before paying for anything the S corporation needs to run.

3. Why a third of the saving comes back

The income tax goes up because of the 20% deduction under section 199A. Wages an S corporation pays its owner are not qualified business income, so only the $74,645 on the K-1 earns the deduction. That is $14,929. As a sole proprietor the same owner had $139,403 of qualified business income. That is profit less the deductible half of self-employment tax, per Treasury Regulation 1.199A-3. The deduction there was capped at 20% of taxable income, $24,661.

A comparison that looks only at payroll tax overstates the saving by that $3,453. If your taxable income is above $201,750 single or $403,500 joint for 2026, the QBI thresholds in Rev. Proc. 2025-32, the interaction changes again, because W-2 wages start to help the deduction instead of only shrinking it. Service businesses such as consulting, accounting, law and medicine work differently: the deduction on that business's income phases out between those thresholds and $276,750 single or $553,500 joint, and wages do not bring it back. That is a separate calculation, and it is one reason a higher earner should model the election rather than read it off a rule of thumb.

4. What "reasonable" means to the IRS

The IRS states the rule plainly on its S corporation compensation page: the company must pay reasonable compensation to a shareholder-employee for services before it makes non-wage distributions. It looks at where the gross receipts come from. Revenue your own work produces points to wages. Revenue from employees who are not owners, or from equipment and capital, can support distributions.

The case the IRS cites is David E. Watson, P.C. v. United States. Watson, a CPA with a master's in taxation, paid himself $24,000 a year through his S corporation. The corporation received $203,651 of profit from his accounting firm in 2002 and passed what was left to him as distributions. The district court found the fair market value of his services was $91,044, which meant $67,044 of each year's distributions were really wages, and the Eighth Circuit affirmed in 2012. Employment taxes were owed on that difference.

The factors the IRS lists include your training and experience, duties, time devoted to the business, what comparable businesses pay for similar services, and what you pay employees who are not owners.

5. How to set a salary you can defend

There is no percentage in the Code or the regulations. The 60/40 split that circulates online has no source in the law.

• Price the job, not the profit. Write down what you actually do: the selling, the delivery, the management. Ask what it would cost to hire someone to do it. Occupational wage data from the Bureau of Labor Statistics, by occupation and metro area, is a reasonable starting point.
• Split the roles if you wear several. An owner who spends half the week on bookkeeping and half on licensed work should not be priced at either rate alone.
• Credit what others produce. If two employees generate most of the revenue, a salary below the profit is easier to support, and the IRS page says so.
• Write it down. A short memo or board minute with the data you used, dated when you set the salary, is worth more in an exam than any after-the-fact argument.
• Revisit it each year. A salary that fit $90,000 of profit does not automatically fit $300,000.

6. What the election costs to run

The $7,032 is before any of this, and some of it recurs every year:

• Payroll. A payroll provider, quarterly Form 941 filings, a W-2, and state unemployment registration. Federal unemployment tax is 0.6% of the first $7,000 of wages, or $42 a year, in states without a credit reduction. California employers paid $126 per employee for 2025 because of one.
• A second return. Form 1120-S and a K-1, due March 15. For 2026 returns that is Monday, March 15, 2027.
• State tax. Some states tax S corporations directly. California charges 1.5% of S corporation income with an $800 minimum, which on the K-1 profit above is about $1,120.
• Health insurance mechanics. Premiums for an owner of more than 2% go on the W-2 as wages to get the self-employed health insurance deduction. Skip that step and the deduction is lost.
• Retirement room. In a 401(k), the employer contribution is limited to 25% of W-2 pay, so a $70,000 salary caps it at $17,500, on top of your own employee deferrals, within the overall annual cap on total contributions. Owners who want to put away more than that sometimes raise the salary on purpose.
• Social Security. Benefits follow the earnings on your record. Lower wages now mean a lower benefit later.

7. When the election stops paying

At low profit, a market salary eats most of it. A business that clears $50,000 for an owner doing full-time skilled work has little left to distribute once a defensible salary is paid, and the payroll and second return cost money every year whether or not anything is saved.

At high profit, the saving per dollar falls once the sole proprietor would have passed the Social Security wage base, and the QBI interaction stops being simple. In between, the election often pays, but the size of the win depends on the salary the facts support, the state, and how the owner wants to fund retirement. We run both versions of the return before recommending it.

8. Deadlines that decide which year it covers

An LLC or corporation elects with Form 2553, and for a calendar-year business the date to remember is March 15 of the year you want covered. The Form 2553 instructions set it at 2 months and 15 days into the tax year, and you can also file any time in the year before. For a calendar-year business that wants S status for 2027, the deadline is March 15, 2027. An LLC that files Form 2553 is treated as electing corporate status at the same time and does not need a separate Form 8832.

Miss it, and Rev. Proc. 2013-30 gives a path to late relief in many cases, generally within 3 years and 75 days of the date the election was meant to take effect, if the business has reasonable cause and has acted consistently with S status. Whichever year the election starts, run payroll from the first month. A single catch-up paycheck in December is the pattern we work hardest to avoid, because it makes the salary look like an afterthought.

9. What to do before electing

• Run both returns. Compare total federal and state tax, not payroll tax alone, with the QBI deduction in both versions.
• Set the salary from the job. Use wage data for the work you do, and keep the memo.
• Price the running costs. Payroll, the 1120-S, state minimums and your time.
• Decide on retirement first. If you want large 401(k) contributions, the salary may need to be higher than the minimum you could defend.
• Start payroll in January. Regular paychecks, withholding and quarterly filings from the first month.

Our tax planning work starts with that side-by-side. We set the salary from market data for the work you actually do, run the payroll, and prepare the 1120-S and your K-1, so the numbers on all three agree. Book a call with last year's Schedule C and a rough split of where your week goes. If the election does not clear its costs at your profit level, we will tell you that before you file anything.
