S-corp vs sole proprietor
The S-corp pitch is simple: pay yourself a reasonable salary, take the rest as distributions, and stop paying self-employment tax on the distribution half. Whether that beats the extra paperwork depends on three numbers, here they are.

Estimate, not advice
The formula
Sole prop: profit × 92.35% × 15.3% (SS capped at the wage base). S-corp: salary × 15.3% (SS capped), distributions free of payroll tax. Net = the difference minus your extra running costs.
What this ignores
Federal income tax (lands on the full profit either way, roughly), the QBI deduction (the salary split changes it), state franchise taxes, and reduced Social Security credits from a lower salary. Below ~$80k profit the election rarely pays. Talk to a CPA before electing.

Field notes
- What counts as a 'reasonable salary'?
- What you'd pay a stranger to do your job, comparable-role market data is the IRS's yardstick. 40–60% of profit is a common outcome for service businesses. $20k salary on $200k profit is how audits start.
- At what profit level does an S-corp start paying?
- Rule of thumb: ~$80–100k+ of consistent profit. Below that, payroll costs and admin eat the savings, exactly what the net-savings line here shows you.
- What costs does the election add?
- Payroll service (~$500–800/yr), a separate 1120-S return (~$800–1,500), possible state franchise taxes, and the discipline of running actual payroll for yourself. Budget $1,500–3,000 all-in annually.
