LLC, S-Corp, or C-Corp? Compare exactly what each structure costs you in tax on your real numbers — including the S-Corp salary math.
The same profit can be taxed three very different ways depending on how your business is structured. Compare a sole proprietorship/LLC, an S-Corporation, and a C-Corporation side by side — with the S-Corp "reasonable salary" math done for you.
Educational estimate — 2026 federal law (Rev. Proc. 2025-32): SE tax with the $184,500 Social Security wage base, simplified 20% QBI deduction, standard deduction, C-Corp 21% flat rate with remaining profit paid as qualified dividends. Assumes single owner. Not covered: retirement-plan differences, health-insurance treatment, accumulated earnings, payroll timing, or the late S-election rescue (Rev. Proc. 2013-30) — that's what the strategy session is for. Changing entity type has legal and administrative consequences beyond taxes; never elect based on a calculator alone.
