LLC vs. S-Corp: When Does the Extra Paperwork Pay Off?

The tool compares simplified self-employment tax on all profit with payroll tax on the salary entered, then subtracts compliance cost. It helps test whether the payroll-tax difference is large enough to matter.

It does not calculate income tax, benefits, state franchise taxes, payroll administration, or every entity rule. Those omissions are the reason the result is a conversation starter rather than a formation decision.

An S-Corp owner who performs services generally needs reasonable compensation before distributions. A low salary chosen only to maximize the estimate is not a sound planning assumption.

Test an optimistic and a conservative salary, include an honest annual cost, and use the range to decide whether professional advice is worth paying for.
