Sole Proprietorship vs LLC: When to Upgrade
The short answer: upgrade to an LLC the moment you take your business seriously. But here's the detailed breakdown of exactly what you gain, what it costs, and when it matters.
Head-to-Head Comparison
| Factor | Sole Proprietorship | LLC |
|---|---|---|
| Formation cost | $0 | $50–$500 (state filing fee) |
| Annual cost | $0 | $0–$800/yr (varies by state) |
| Liability protection | None — personal assets at risk | Yes — business debts stay with the business |
| Tax filing | Schedule C on personal return | Same (single-member LLC) |
| Self-employment tax | 15.3% on net earnings | Same (unless S-Corp elected) |
| Business credit | Cannot build separately | Can build business credit with EIN |
| Bank account | Personal or DBA account | True business bank account |
| Credibility | "John Smith" | "Smith Consulting LLC" |
| Perpetuity | Ends when you stop | Entity persists independently |
The Trigger Points: Upgrade When Any of These Are True
→ You earn more than $5K/year from the business
→ You sign contracts with clients or vendors
→ You have any customer-facing interactions with liability risk
→ You want a business bank account or credit card
→ You're hiring contractors or employees
→ You want to look professional to clients and partners
→ You're keeping the business long-term (not just a weekend experiment)
The Only Time to Stay as a Sole Prop
→ Testing an idea for less than 90 days before deciding to commit
→ Earning under $1K from an extremely low-risk hobby (selling crafts at a market)
→ You have zero client interaction and zero liability exposure
