How we calculate this
This calculator quantifies how much FICA an S-corp owner's salary/distribution split saves compared with taking the entire profit as salary, and shows where the chosen salary sits relative to common reasonable-compensation risk bands. Every dollar shifted from salary to distribution saves about 15.3¢ up to the Social Security wage base ($184,500 for 2026) and 2.9¢ above it — but the IRS requires reasonable compensation for the work you actually perform, so the split is a bounded dial, not a free lunch.
The formulas
- FICA on a salary
- 15.3% × min(salary, Social Security wage base) + 2.9% × max(0, salary − wage base)Both economic halves (employer + employee) are counted, since the owner bears both. The wage base is $184,500 for 2026, $176,100 for 2025.
- Annual FICA savings
- FICA if the entire profit were salary − FICA on your chosen salary
- Distributions
- net income before salary − salary − employer half of FICA (7.65% of salary up to the base)The employer FICA half is a deductible business cost, so it reduces what is left to distribute.
- Risk banding (rule of thumb, not an IRS rule)
- salary ÷ net income: under 30% high audit-flag territory; 30–40% aggressive; 40–60% commonly considered reasonable; over 60% conservative
Worked example
- Take the defaults: $150,000 of net income before salary, a $70,000 salary, tax year 2026.
- FICA on the $70,000 salary = 15.3% × $70,000 = $10,710 (well under the $184,500 wage base).
- If the whole $150,000 were salary, FICA would be 15.3% × $150,000 = $22,950.
- Annual FICA savings = $22,950 − $10,710 = $12,240.
- The employer half of FICA (7.65% × $70,000 = $5,355) is a business expense, leaving $150,000 − $70,000 − $5,355 = $74,645 of FICA-free distributions.
- The salary is 46.7% of income — inside the 40–60% band that rule-of-thumb audit heuristics treat as a reasonable range.
Rates, benchmarks & sources
- FICA rates (12.4% Social Security + 2.9% Medicare = 15.3%) and the Social Security wage base ($184,500 for 2026; $176,100 for 2025) — SSA (2025-10-24); IRS; PayrollOrg (2026)
- The requirement that S-corp owner-employees take reasonable compensation for services performed — the requirement is IRS law; the specific percentage bands are not — IRS reasonable-compensation standard (facts-and-circumstances)
- The 30/40/60% salary-ratio risk bands used for the verdict shading — audit heuristics, not IRS rules or thresholds — Industry rule of thumb

What this tool doesn’t model
- The percentage risk bands are rules of thumb. The IRS has no published "safe" salary ratio — reasonable compensation is a facts-and-circumstances test based on your role, hours, skills, and what comparable businesses pay for the same work.
- FICA only — this tool does not compute income tax, the QBI deduction (which salary reduces), or state taxes; run the Entity Comparison tool for the full federal picture including compliance costs.
- The employee-side 0.9% additional Medicare tax above $200,000 of wages is noted but not added to the savings math.
- Lower salary means lower reported Social Security earnings, which can reduce future Social Security benefits — that long-term cost is not modeled.
- Educational estimate only — setting owner compensation is a judgment call to document with a CPA, not something a calculator can decide.
Frequently asked questions
Is there an official IRS-approved salary percentage?
No. The IRS requires reasonable compensation but has never published a percentage or safe-harbor ratio — the bands this tool shades (under 30% high risk, 40–60% commonly reasonable) are practitioner rules of thumb drawn from audit experience, not IRS rules. What actually matters in an exam is evidence: comparable salaries for your role, your hours, and documentation of how you set the number.
What happens if the IRS decides my salary is too low?
It can reclassify distributions as wages, which triggers back payroll taxes on both halves of FICA plus penalties and interest. Court cases consistently look at what you would have to pay someone else to do your job. That is why the savings from an aggressively low salary are not free — they carry reclassification risk that grows as the ratio drops.
Why do my savings per dollar drop once my salary passes $184,500?
Social Security tax (12.4%) stops at the wage base — $184,500 for 2026 — so above it only the 2.9% Medicare portion continues. Each dollar shifted to distributions below the base saves about 15.3¢; above the base it saves only 2.9¢. The tool marks this "kink" because for high earners most of the FICA savings are already captured by the time salary reaches the base.
Does a lower salary affect anything besides FICA?
Yes, several things. It shrinks your future Social Security benefit basis, caps how much you can defer into a 401(k) as employee salary deferrals, reduces the W-2 wages available for QBI limits at high incomes, and can matter for mortgage or disability underwriting. The FICA savings shown here are one side of a broader trade-off this tool does not fully model.
Does this include income tax or state taxes?
No — it isolates FICA (payroll tax) only, because that is what the salary/distribution split changes most directly. Federal income tax largely applies to salary and distributions alike, though salary reduces the QBI deduction. State income and franchise taxes are excluded entirely. Treat this as a federal payroll-tax estimate, not filing advice or a complete comparison.
