LLC vs S-Corp Calculator

FIN·US

The S-corp question, priced honestly for 2026: how much payroll tax the structure actually saves at your profit and a defensible salary — and the rule that stops you setting that salary to $1.

On $100,000 of profit with a $60,000 salary in Texas: LLC self-employment tax is $14,130; S-corp payroll tax on the salary is $9,180; the model saving is about $4,405 a year — before S-corp running costs. The saving exists only on profit above the salary, and the salary must be reasonable compensation for the work, or the IRS reclassifies the distributions as wages.

The business Profit and the salary you would pay yourself.

Reasonable compensation is the law, not a dial: the IRS can reclassify distributions as wages (with back taxes and penalties) when the salary is set artificially low for the work performed. Model salaries you could defend.

The model saving
At a $60,000 salary on $100,000 of profit, the S-corp structure saves about $4,405 a year in payroll/SE taxes in this model — before S-corp running costs (payroll service, separate return, state franchise fees where they apply).

Distribution above salary: $40,000 — the only part that escapes payroll tax.

The caveats that decide whether the saving is real

Running costs eat small savings

An S-corp needs payroll (even for one person), a separate Form 1120-S return, state filings, and in some states a franchise tax or minimum fee. Below roughly $40,000–$60,000 of profit, those costs commonly consume the entire payroll saving — the model above shows the gross saving so you can judge it against real quotes.

Method note: running costs excluded from the arithmetic and stated here, per this page's model.

Reasonable compensation (IRS)

Shareholder-employees must be paid reasonable compensation before distributions; courts have reclassified distributions for underpaid owners (the IRS's published position, FS-2008-25 and the Form 1120-S instructions). A salary set purely to dodge payroll tax is the audit trigger, not the strategy.

QBI interacts

Wages paid by an S-corp can support the §199A deduction at higher incomes, while LLC profit may qualify differently — one of several reasons this page models payroll taxes only and labels the rest.

Frequently asked questions

At what profit does an S-corp start winning?

When the payroll-tax saving (roughly 15.3% of the profit above a defensible salary) clearly exceeds the year's running costs — for many one-person businesses that crossover sits around $40,000–$60,000 of profit.

Is the income tax different between the two?

Barely: both are pass-throughs taxed once at your rates. The model applies the same engine to both, with each structure's payroll deduction; the difference you see is essentially the payroll-tax line, which is the honest story.

Can an LLC elect S-corp taxation?

Yes — an eligible LLC can file Form 2553 (or check-the-box plus 2553) and keep its LLC legal form with S-corp tax treatment. This page compares the tax treatments, not the legal forms.

LLC vs S-Corp Calculator — the Payroll-Tax Saving, Honestly Framed guide

What an S-corp election actually saves in payroll tax at your profit and a defensible salary for 2026 — with the reasonable-compensation rule and the running costs that eat small savings.

How to use this tool

  1. Enter the business profit.
  2. Enter a salary you could defend as reasonable compensation.
  3. Set status and state.
  4. Compare the two total-tax columns and judge the saving against S-corp running costs.

A worked example

On $100,000 of profit with a $60,000 salary (Texas, single), the model saving is roughly $4,000 a year before running costs.

What you can do with this tool

How it works

The saving is payroll tax on the distribution — profit above the salary. Set the salary to zero and the model lies; the IRS reclassifies, so the page will not help you pretend otherwise.

Frequently asked questions

When does the S-corp start winning?

When the payroll saving clearly beats payroll-service, return-preparation and state fee costs — often around $40,000–$60,000 of profit.

Can an LLC be taxed as an S-corp?

Yes — Form 2553 election; the legal form stays an LLC.
