Elect it for the right reason, or not at all.

Who this is for

The S election is oversold. It is genuinely valuable in a specific band and a net negative outside it. You are in the band worth analyzing if most of this describes you.

• A single member or multi member LLC with net profit somewhere between roughly eighty thousand and three million dollars
• An owner who actually works in the business rather than holding a passive interest
• Profit that is meaningfully above what you would have to pay someone else to do your job
• Willingness to run real payroll, file a separate entity return, and keep the formalities
• An existing S corporation where nobody has ever documented the compensation position or tracked basis

The math, at three profit levels

Illustrative only, single owner filing single, before state tax and before the cost of compliance. Figures use the 2026 Social Security wage base of $184,500 and include the 0.9 percent Additional Medicare Tax above $200,000. The point is the shape of the curve, not your specific number.

• $90,000 profit. A sole proprietor pays self employment tax on 92.35 percent of profit, so roughly $12,700. An S corporation paying a $65,000 wage pays payroll tax on the wage alone, roughly $9,900, and the distribution escapes. Gross saving around $2,800. Note that this is well below the $3,825 you get by multiplying the distribution by 15.3 percent, because that shortcut ignores the 92.35 percent adjustment. Subtract payroll service, the 1120-S and the added bookkeeping and the real benefit is thin. Often a no.
• $200,000 profit. A $110,000 wage leaves roughly $90,000 as distribution. The sole proprietor pays the 12.4 percent Social Security portion right up to the wage base; the S corporation pays it only on the wage. That is where most of the difference comes from, and the saving lands near $11,400, commonly $8,000 to $13,000 depending on the wage you can defend. This is the band where the election usually pays.
• $600,000 profit. A $180,000 wage leaves a large distribution, and the saving is around $14,600. Less than most people expect, and worth understanding why: both sides have run past the Social Security wage base, so that portion is capped for everyone and contributes almost nothing. What is left is the 2.9 percent Medicare differential on the gap, about $10,800, plus $3,200 of Additional Medicare Tax the wage stays under. The saving grows with the gap between profit and wage rather than with profit, which is why examination interest lands squarely on whether the wage is defensible. At this level the compensation study stops being paperwork and starts being the whole point.
• The variable that decides it is not profit. It is the gap between profit and a defensible wage. A business whose owner is the entire product cannot claim a small wage, no matter how profitable it is.

What else the election moves

Self employment tax is the reason people ask about the election, and it is not the only thing that changes. Several of these run the other way, which is why the answer is sometimes no even when the payroll tax arithmetic looks good.

• The qualified business income deduction. Reasonable compensation is not qualified business income, so every dollar of wage reduces the section 199A base. Above the income thresholds the same wages can do the opposite and unlock the W-2 wage limitation. Which effect dominates depends on your taxable income and your business, and it can be worth more than the payroll tax saving in either direction.
• Your retirement contribution ceiling. A solo 401(k) or SEP employer contribution is calculated from W-2 wages once you are an S corporation, not from net self employment income. Set the wage low enough to win on payroll tax and you can cap the contribution you were counting on.
• Health insurance. Premiums for a more-than-2-percent shareholder have to run through the W-2 to stay deductible. It is a reporting step people miss in the first year and it costs the deduction when they do.
• Your future Social Security benefit. A lower reported wage is a lower earnings record. The payroll tax you avoid is also a benefit you do not accrue, which matters more the further you are from the wage base and the closer you are to claiming.
• How losses reach your return. S corporation basis rules are their own regime. A shareholder gets no basis from guaranteeing corporate debt, where a partner often would, so a loss that would have been deductible can be suspended instead. This is what Form 7203 exists to track.
• Estimated payments. Withholding from a W-2 is treated as paid evenly across the year regardless of when it was actually withheld, which can cure an underpayment position late in the year in a way a fourth-quarter estimate cannot.
• State treatment. Some states pick up a separate entity filing obligation, and some open an entity-level tax election that is only available once you are a pass-through. Both are worth checking before electing, not after.

How we document reasonable compensation

A number you cannot explain is a number you will eventually have to give back. We build the position before the first payroll run, not after a notice.

• A written duties analysis: what you actually do, how many hours, and which of those functions a hired employee would perform
• Market wage data for comparable roles in your metro, sourced and dated, not recalled from memory
• The cost approach where your role splits across functions, valuing each separately rather than guessing one blended figure
• Consideration of what the company earns, what capital is at risk, and what it distributes, since courts weigh all three
• A memo retained in your file that an examiner can read and follow, refreshed when the business changes materially
• An explicit revisit each year rather than a wage set once in 2019 and never touched again

What the engagement includes

Whether the answer turns out to be yes or no.

• Modeled comparison of your current structure against an S corporation at your actual numbers, including state effects
• A written recommendation, including the recommendation not to elect where that is the honest answer
• Form 2553 preparation and filing, including late election relief under Revenue Procedure 2013-30 where it applies
• Payroll setup and coordination, quarterly Forms 941, and the annual 940 and W-2
• Form 1120-S and shareholder K-1s
• Form 7203 basis tracking, rebuilt from prior years where nobody has been keeping it
• Distribution planning through the year so basis is not exceeded and a distribution does not become a capital gain
• Wisconsin Form 5S, Texas franchise tax and public information report, or Colorado filings as applicable

When we tell people not to do it

We decline this engagement often enough that it is worth stating plainly. An S election is a poor fit when profit is too low to clear the compliance cost, when the owner is the entire economic engine and no low wage is defensible, when there are foreign or ineligible shareholders, when the business plans to raise outside capital or issue more than one class of stock, when losses are expected and basis will limit their deductibility, or when the owner will not run real payroll on a real schedule. Any of those turns a tax saving into an examination risk with extra bookkeeping attached.
