How S-Corp Election Reduces SE Tax
Without S-corp: a consultant earning $150,000 pays SE tax on all $150,000 (after the 92.35% factor). With S-corp: she pays herself a $80,000 reasonable salary (subject to payroll taxes, similar to SE tax) and takes $70,000 as distributions. SE tax applies only to the $80,000 salary. SE tax savings: approximately 14.1% × $70,000 = $9,870 per year.

The IRS requires S-corp owner-employees to pay a 'reasonable salary' for services performed — typically 40–60% of total S-corp income or the market rate for the work. Artificially low salaries to maximize distributions are an audit target. Your CPA should document the reasonable salary determination.
