Entity Type Calculator — LLC vs S-Corp vs Sole Prop

Answer five questions about your business and we'll show which entity structure fits, the rough tax implications, and the breakeven point for an S-Corp election — with the actual numbers, not vague advisor-speak.

The five-minute version

If your annual net profit is under $60,000–$80,000, stay as a default LLC taxed as a sole proprietor. The S-Corp's compliance costs (payroll setup ~$500, processing ~$1,200/yr, Form 1120-S accounting ~$1,500–$3,000/yr) will eat the self-employment tax savings.

If you're consistently above $80K net profit, the S-Corp election can save you real money. At $100K net profit, the typical S-Corp election saves roughly $4,000–$6,000/yr in self-employment tax after compliance costs.

The five questions that determine your entity

  1. What's your projected annual net profit? Under $30K → sole proprietor or LLC. $30K–$80K → LLC. $80K+ → LLC with S-Corp election.
  2. Do you have employees or plan to hire? Yes → LLC mandatory. No → sole prop is still legal but exposes personal assets.
  3. Are you raising venture capital? Yes → Delaware C-Corp. No → LLC.
  4. Are you bringing significant assets (IP, real estate, contracts) into the business? Yes → LLC with attorney-drafted operating agreement. No → simple single-member LLC.
  5. Are you in California? Yes → budget for the $800/yr franchise tax regardless of profit. No → your annual costs are likely $0–$300.

The decision tree

  • Sole Proprietor — No formal structure, no liability protection. Cost: $0. Right for: testing an idea, hobby-tier revenue under $10K/yr.
  • Single-Member LLC — Liability shield, pass-through taxation. Cost: $35–$500 + annual fees. Right for: most bootstrapped founders earning $10K–$80K net.
  • LLC + S-Corp Election — Liability shield, pass-through, payroll-tax savings on distributions. Cost: $35–$500 + $2,000–$4,000/yr compliance. Right for: consistent $80K+ net profit.
  • C-Corporation — Liability shield, double taxation, investor-friendly. Cost: $100–$500 + significant compliance. Right for: VC-backed startups, public company path.
