How the comparison works

As a sole proprietor or single-member LLC, all of your profit is subject to self-employment tax of 15.3% (on 92.35% of profit, up to the 2026 Social Security wage base of $184,500). As an S corporation, payroll taxes apply only to the salary you pay yourself; the rest of the profit passes through without them.

The trade-offs: payroll and a separate return cost money, and your salary is not qualified business income, so the 20% QBI deduction can shrink. The calculator weighs all three.

Common questions

At what profit does an S corporation start to make sense?

There is no single number. The savings come from paying self-employment tax only on a reasonable salary instead of all profit, and they have to outweigh payroll costs, a separate return and any loss of the qualified business income deduction. For many owners the math starts to work somewhere above $60,000 to $80,000 of steady profit, but the calculator shows your own break-even.

Why can an S corporation reduce my QBI deduction?

The 20% qualified business income deduction is calculated on business profit, and the salary you pay yourself from an S corporation is not qualified business income. A higher salary lowers the deduction. Above the 2026 income thresholds, though, W-2 wages can help you keep the deduction, which is why the result can swing either way.

How is "reasonable compensation" decided?

The IRS expects an S corporation owner who works in the business to take a salary comparable to what the business would pay someone else for the same work. It looks at the duties performed, the time spent and local pay for similar roles. Our reasonable compensation calculator builds that estimate from local wage data.

What costs come with running an S corporation?

Payroll processing, quarterly and annual payroll filings, a separate Form 1120-S return, and in Colorado state unemployment and FAMLI premiums on the salary. The calculator includes an annual amount for these costs that you can change.

Does this include Colorado tax?

Yes. It applies Colorado’s 4.4% income tax for 2026 to federal taxable income and adds back the QBI deduction where Colorado requires it at higher incomes. It does not include credits, itemized deductions or taxes in other states.
