How to use the S Corp tax calculator
Enter your expected net profit, a reasonable W-2 salary, and your filing status. The tool estimates payroll tax on wages and self-employment tax savings on distributions—use it as a planning range before you set payroll with your CPA.
IRS rules require S-Corp owners who perform services to pay themselves a reasonable salary before taking distributions. If salary is set too low, audit risk rises; if too high, payroll tax wipes out the benefit. Run a few salary scenarios and compare to staying on Schedule C.
Worked example (illustrative)
Suppose net profit is $120,000 and you pay yourself a $70,000 W-2 salary. On Schedule C, self-employment tax applies to the full $120,000 (15.3% on net, with the Social Security wage base cap). As an S-Corp, payroll tax (employee + employer share, roughly 15.3% combined on wages) hits only the $70,000 salary; the remaining $50,000 distribution avoids self-employment tax—though it still faces income tax. Savings might be on the order of $7,000–$8,000 before payroll service and filing costs—not tax advice. Run your salary and profit in the S Corp tax planning calculator; confirm reasonable compensation with a CPA before filing Form 2553.
