S-Corp Tax Savings Calculator

See whether electing S-corp status saves you money in 2026 — self-employment tax avoided on distributions, net of payroll costs and the reasonable salary the IRS requires.

How to use this calculator

  1. 1Enter your business profit after expenses but before paying yourself anything.
  2. 2Set a reasonable salary — what you would have to pay someone else to do your job. For owner-operators this commonly lands at 40–60% of profit.
  3. 3Add the real extra cost: payroll software, the additional accounting, and the separate S-corp tax return.
  4. 4Check the net saving. Below roughly $2,000 a year the added complexity and audit exposure rarely justify the election.

How the calculation works

Saving = SE tax on full profit − payroll tax on salary − cost of running payroll. SE tax = 15.3% × 92.35% × profit; payroll tax = 12.4% × min(salary, wage base) + 2.9% × salary
reasonable salary
What the IRS requires you to pay yourself for the work you do — the figure the whole strategy depends on
distributions
Profit taken above the salary, which is not subject to payroll tax
wage base
The Social Security ceiling — $184,500 for 2026, above which only Medicare applies

The saving comes entirely from payroll tax, not income tax. All the profit reaches your personal return either way and is taxed at the same rates — only the FICA treatment differs.

Once the salary passes the Social Security wage base, the only tax avoided on distributions is the 2.9% Medicare component, so the benefit flattens sharply for high salaries.

The IRS has no formula for a reasonable salary. It is judged on facts — what the role would pay someone else, your hours, your experience and industry comparables. A salary set too low to maximise the saving is the classic way this strategy fails on audit.

Worked example

$150,000 profit with a $75,000 salary

  1. 1.As an LLC: self-employment tax on 92.35% of $150,000 = $138,525, at 15.3% ≈ $21,194.
  2. 2.As an S-corp: payroll tax on the $75,000 salary only — 12.4% + 2.9% = 15.3% of $75,000 ≈ $11,475.
  3. 3.The $75,000 taken as distributions escapes payroll tax entirely, saving roughly $9,700.
  4. 4.Subtracting $2,500 of payroll and filing costs leaves a net saving around $7,200 a year.

Result: Roughly $7,200 a year saved, net of costs

Why it does not work at low profit

  1. 1.A $50,000 profit supporting a defensible $40,000 salary leaves only $10,000 of distributions.
  2. 2.Payroll tax is avoided on that $10,000 alone — about $1,530.
  3. 3.That does not cover the $2,500 cost of running payroll and filing the extra return.
  4. 4.The election loses money, which is why it rarely makes sense below roughly $60,000–$80,000 of profit.

Result: A net loss — the election is not worth making

What the S-corp election actually does

An S-corp is not a type of company. It is a tax election that an LLC or corporation makes with the IRS, and it changes one thing: how the owner's income is split for payroll tax purposes.

A sole proprietor or single-member LLC pays self-employment tax — 15.3% for Social Security and Medicare — on essentially all business profit. With an S-corp election, the owner becomes an employee of their own company and must be paid a reasonable salary, on which normal payroll taxes apply. Profit taken above that salary is a distribution, and distributions are not subject to payroll tax at all.

That is the entire mechanism. Income tax is unchanged: all the profit still flows through to the personal return and is taxed at the same rates. The saving is purely the 15.3% avoided on the distribution portion.

Reasonable salary is where this succeeds or fails

The obvious move — pay yourself $10,000 and take $140,000 as distributions — is also the fastest route to an audit. The IRS requires the salary to be reasonable compensation for the services actually performed, and it litigates this regularly. When a salary is found unreasonably low, distributions are reclassified as wages, and back payroll taxes, interest and penalties follow.

There is no statutory formula. The IRS looks at what the role would pay in the open market, the owner's training and experience, hours worked, what comparable businesses pay, and how much of the profit is attributable to the owner's labour rather than to capital or employees. Practitioners commonly land at 40–60% of profit for an owner-operator whose work generates essentially all the revenue, but a business with substantial staff or invested capital can justify a lower proportion because less of the profit comes from the owner personally.

The costs and complications that offset the saving

The payroll tax saving is real, but it is not free, and the offsetting items are why the election is wrong for many small businesses.

  • Running payroll — the owner must be on formal payroll with withholding, quarterly filings and W-2s. A payroll service plus the extra accounting typically runs $1,500–$5,000 a year.
  • A separate tax return — the S-corp files Form 1120-S and issues a Schedule K-1. That is a second return to prepare and pay for, every year.
  • A smaller Social Security record — benefits are calculated from wages. Years of a deliberately low salary reduce the earnings history the eventual benefit is based on.
  • Reduced retirement contribution room — solo 401(k) employer contributions are calculated from W-2 wages in an S-corp, so a low salary caps how much can be contributed.
  • State-level treatment — several states impose franchise taxes or fees on S-corps, and a few do not recognise the election at all — which can erase the federal saving entirely.

What this assumes, and where it stops

Assumptions

  • The business is profitable and the owner materially participates in it.
  • The salary entered would withstand IRS scrutiny as reasonable compensation.
  • Payroll taxes on the salary are borne entirely by the owner, since the company and the owner are the same economic party.
  • Federal treatment only, using 2026 rates.

Limitations

  • State taxes, franchise fees and states that do not recognise the S-corp election are not modelled, and can reverse the conclusion.
  • The QBI deduction interacts with the salary/distribution split in ways not captured here, and can favour a different balance.
  • Effects on Social Security benefits and retirement contribution room are described but not quantified.
  • This is a planning estimate. Making the election is a formal step with ongoing obligations — take professional advice before filing Form 2553.

Common questions

At what profit level does an S-corp election start to make sense?

Usually somewhere above $60,000–$80,000 of net profit, though it depends on the salary you can defend and what payroll costs you locally. Below that, the distributions left after a reasonable salary are too small for the 15.3% saving to cover the $1,500–$5,000 of extra payroll and filing costs. This calculator shows the net figure directly, so you can find your own crossover rather than rely on a rule of thumb.

What counts as a reasonable salary?

What you would have to pay someone else to do your job. The IRS weighs your duties, hours, training and experience against what comparable roles pay in your industry and area, and considers how much profit comes from your labour versus from capital or employees. There is no safe-harbour percentage, but 40–60% of profit is a common landing point for owner-operators. Documenting how you arrived at the figure matters as much as the figure itself.

Does an S-corp reduce my income tax as well?

No. All the profit still flows to your personal return and is taxed at the same rates either way. The election only changes payroll tax treatment, by exempting distributions from the 15.3% that would otherwise apply to the whole profit. Anyone promising income tax savings from an S-corp election is describing something the structure does not do.

What are the downsides nobody mentions?

A lower salary means a smaller Social Security earnings record, which reduces your eventual benefit. Solo 401(k) employer contributions are calculated from W-2 wages, so a low salary also caps retirement contributions. You take on real payroll compliance — missed filings carry penalties. Several states levy franchise taxes on S-corps or ignore the election entirely. And an unreasonably low salary invites reclassification with back taxes and penalties.
