S-Corp Salary vs Distribution Tax Calculator

The calculator builds a sole-proprietor baseline first. It applies the 92.35% net earnings factor for self-employment tax, the 2026 Social Security wage base, Medicare tax, Additional Medicare Tax where applicable, the deductible half of SE tax, the 2026 standard deduction, and a simplified QBI deduction.

It then builds the S-corp scenario. Proposed shareholder salary is treated as W-2 wages subject to employee payroll tax and employer payroll tax. Employer payroll tax and extra S-corp admin cost reduce the corporation's pass-through profit and the amount available for shareholder distributions.

The final comparison shows the sole-proprietor tax baseline minus the S-corp federal tax, employee payroll tax, employer payroll tax, and admin cost. It also flags when the proposed salary is below the benchmark while distributions are modeled.

The S-corp tax strategy is not distribution-only

S corporations are popular because shareholder distributions are generally not treated as payroll wages. That can reduce Social Security and Medicare tax compared with a sole proprietor who pays self-employment tax on net earnings. But the strategy only works when the shareholder-employee is paid reasonable compensation for services provided to the corporation.

IRS guidance says an S corporation must pay reasonable compensation to a shareholder-employee before non-wage distributions are made. IRS guidance also states that corporate officers who perform services and receive or are entitled to payments are employees for FICA and federal income tax withholding purposes. That is why this calculator treats salary as the first planning variable, not as an afterthought.

What changes when salary goes up

A higher S-corp salary usually increases employee and employer payroll taxes. It also reduces pass-through profit, because wages and employer payroll taxes are corporate deductions. Lower pass-through profit can mean less distribution capacity and less QBI. On the other hand, S-corp W-2 wages can help the Section 199A wage limitation for higher-income owners.

Reasonable compensation is a documentation question

There is no single IRS safe-harbor percentage that says an S-corp owner salary is automatically reasonable. A salary that looks acceptable for a capital-heavy business with employees may look weak for a one-owner consulting practice where most revenue comes from the shareholder's personal services. The calculator therefore asks for a benchmark salary instead of guessing one.

Good support can include comparable wage data, job duties, hours worked, training, certifications, revenue generated by non-owner employees or equipment, local labor market facts, distributions taken, and the company's ability to pay. If the proposed salary is lower than the benchmark while distributions are planned, the calculator displays a reclassification exposure estimate.

How this connects to other tax planning tools

Start with clean business profit from the Schedule C profit and tax reserve calculator if your books are still being organized. Use the self-employment tax calculator to isolate the SE tax baseline, and use the QBI 20% deduction calculator when the Section 199A details need a deeper standalone worksheet.

Limits of the calculator

This calculator does not file payroll returns, choose a reasonable salary, or determine whether an S election is appropriate. It also does not model state income tax, pass-through entity tax elections, franchise taxes, accountable plan reimbursements, shareholder basis, accumulated adjustments account, health insurance for 2% shareholder employees, retirement plan contribution limits, multiple shareholders, or built-in gains tax. Treat it as a decision-support worksheet before discussing the final structure with a qualified tax professional.
