How this works: As a default LLC, all profit is subject to 15.3% self-employment tax. As an S-Corp, you pay yourself a "reasonable salary" (subject to payroll taxes) and take the rest as distributions (no SE tax). But S-Corp status adds payroll processing costs and complexity. This calculator finds your break-even.

Before You File Form 2553: Read This

  • S-Corp election requires running actual payroll. You can't just take distributions. The IRS will reclassify them and penalize you.
  • "Reasonable compensation" is judgment-based. Too low = audit risk. Too high = no savings. We help you document and justify the number.
  • WA S-Corps still owe the B&O tax on gross revenue. S-Corp election doesn't change state-level taxes.
  • Once you elect S-Corp, switching back is painful. Make sure it's the right call before filing.
  • Savings shown above are annual. They compound every year you stay an S-Corp.

No spam. Just your results and an optional follow-up.

Estimates only. Uses 2026 projected federal tax brackets, 15.3% SE tax (net of deduction), 7.65% employer + 7.65% employee payroll tax, and standard deduction. Does not account for QBI deduction phase-ins/outs, additional Medicare tax, state-specific credits, or entity-level taxes. Actual savings depend on reasonable compensation justification, profit consistency, and benefit elections. Talk to a CPA before filing.
