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.

⚠️Reasonable Salary Requirement

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.

S-Corp Administration Requirements

  • File S-corp election (Form 2553) within 75 days of incorporation or by March 15 for the current tax year
  • Run payroll for yourself (quarterly payroll taxes, W-2 filing) — adds $1,500–$3,000 in bookkeeping costs
  • File a separate S-corp tax return (Form 1120S) — adds $800–$2,000 in CPA fees
  • Maintain corporate formalities: separate business bank account, minutes, and records
  • Estimated total additional administrative cost: $2,500–$5,000 per year versus sole proprietorship
