Every dollar of sole-proprietor profit pays 15.3% self-employment tax before income tax even begins. The S corporation election splits your income into salary (taxed normally) and distributions (no SE tax) — and that split, done correctly, is worth five figures a year to most established service businesses.
Done incorrectly, it invites payroll tax audits and erases its own savings in fees. Here is the honest math.
Where the Savings Come From
A sole proprietor netting $150,000 pays roughly $21,200 in self-employment tax. Elect S corp status, pay yourself a defensible $70,000 salary, and take $80,000 as distributions: payroll taxes apply only to the salary (~$10,700). Gross savings: about $10,500 per year — before subtracting payroll service and tax prep costs of roughly $2,000–$3,000.
The savings repeat every year you operate. Over a decade, an optimized election commonly keeps six figures out of the Treasury and in your business.
'Reasonable Salary': The Rule That Makes or Breaks It
The IRS requires S corp owners to take reasonable compensation before distributions. Pay yourself $20,000 on $200,000 of profit and you are volunteering for reclassification, back payroll taxes, and penalties.
Reasonableness is factual: your role, hours, expertise, and what comparable businesses pay for that work. We document salaries with market data (a reasonable compensation study) so the number defends itself — typically landing between 35–55% of profit for owner-operated service firms, though facts control, not formulas.
The Break-Even: When Is Profit High Enough?
Below roughly $50,000–$60,000 of net profit, payroll costs, state fees, and extra filings usually eat the savings. Above $75,000, the election gets compelling; above $100,000 it is usually a five-figure decision.
California adds a wrinkle: S corps pay a 1.5% state tax on net income (minimum $800), which we build into every break-even analysis for California businesses.
Second-Order Wins: QBI and Retirement Stacking
The salary you pay yourself creates payroll that supports a Solo 401(k): up to a $24,500 employee deferral in 2026 plus a 25%-of-salary employer contribution — often $40,000+ of combined deductions. And the salary/distribution split interacts with the 20% QBI deduction, which is why the 'lowest defensible salary' is not always the optimal one. This is a modeling exercise, not a rule of thumb.
Execution Checklist
An election only saves money when the operational side is real:
- File Form 2553 on time — or use late-election relief (Rev. Proc. 2013-30) when eligible
- Run actual payroll with withholding and quarterly 941s — not year-end journal entries
- Set up an accountable plan so the company reimburses home office, mileage, and phone tax-free
- Track shareholder basis annually — required for loss deductions and clean distributions
- Revisit salary each year as profit changes; document the reasoning

Business Entity Tax Structuring
Choose the right structure — LLC, S corp, partnership, or holding company.
Explore the serviceFrequently Asked Questions
Can my LLC become an S corp without forming a new company?
Yes. S corp status is a tax election, not a new entity. Your existing LLC files Form 2553 and keeps its name, EIN (usually), bank accounts, and contracts — only its tax treatment changes.
What salary should I pay myself from my S corp?
A defensible market rate for the work you actually perform — commonly 35–55% of profit for owner-operators, but driven by your duties, hours, and industry comparables. We prepare documentation supporting the specific number so it withstands scrutiny.
Do S corps increase audit risk?
S corp payroll compliance is an IRS focus area, but a properly run S corp — real payroll, documented salary, clean books — is routine. The risk concentrates on owners taking little or no salary while living on distributions.
