California LLC vs Sole Proprietorship: A Decision Framework

The default — sole proprietorship

If you're earning money on the side without forming any entity, you're a sole proprietor by default. The IRS taxes you on Schedule C. Your business income is your personal income, just with a different reporting form.

Cost: $0. No filing. No franchise tax. No operating agreement. You can use your name as the business name (or file a DBA / fictitious business name with your county for ~$25-$50 to use a different name).

Tradeoff: zero liability separation. If a customer sues, they can come after your personal assets — house, car, savings.

The upgrade — single-member LLC

An LLC creates legal separation between you and your business. The LLC owns the business assets, contracts with customers, and incurs debts. If the business gets sued, the plaintiff can typically only reach the LLC's assets — not your personal ones.

California cost: $70 filing + $20 every 2 years for Statement of Information + $800/yr franchise tax. First year minimum: ~$890. Ongoing: $810/yr (plus $20 every other year).

Tax treatment: by default, single-member LLCs are 'disregarded entities' — same Schedule C as sole prop. No tax savings, no tax penalty. You can elect S-corp tax treatment later when income justifies it.

The decision factors

• Revenue: under $30k → usually sole prop. $30-50k → maybe. Above $50k → start considering. Above $100k → almost always LLC + S-corp election.
• Liability: if you sell physical products that could harm someone, or services where clients can sue over results, or own rental property — the LLC is worth the $800/yr.
• Assets at risk: if you have meaningful personal assets ($25k+ savings, home equity, retirement), the LLC matters more.
• Co-founders: any partnership needs a legal entity (LLC or partnership). Sole prop doesn't support multi-owner structures.
• Branding: Etsy, Amazon, banking — all easier with an LLC's tax ID than with your SSN.
• Tax: above ~$80k net income, S-corp election (which requires LLC first) starts saving real money. Below that, doesn't matter.

The $800 problem (and why CA is different)

California charges $800/year minimum franchise tax. Period. Even with $0 revenue. Even if your LLC just exists.

This is unique among US states. Most states charge $0-$200/yr. CA charges $800. So 'form an LLC' advice that works in TX or FL doesn't apply unchanged here.

This is the single biggest reason solopreneurs in CA stay sole-prop longer. If you're making $20k/year in side income, $800 of that going to the state for liability protection you might never use is a real cost.

The middle path — DBA + insurance

If you're sole-prop and want some liability protection without forming an LLC, the alternative is general liability insurance ($300-$1000/yr depending on industry) + an EIN (free) + a DBA filing (~$50). This gets you:

Operating under a business name (the DBA), brand separation from your personal name.

1099 forms going to the EIN, not your SSN (better privacy).

Insurance coverage for typical business liability claims.

What it doesn't get you: legal separation. A determined plaintiff with good lawyers can still pierce the 'corporate veil' even on an LLC, and there's no veil at all on a sole prop. Insurance + sole prop is a viable middle path for most freelancers under $50k revenue.

When to upgrade from sole prop to LLC

Trigger events that should push you to LLC:

Revenue crosses $50k consistently for 6+ months

First major contract (>$10k) requires it

First wholesale or B2B contract requires it

A client's legal team asks for it

You're hiring your first 1099 contractor or W-2 employee

You're selling physical products with even moderate liability risk

You buy your first piece of real estate as part of the business

Don't form preemptively just because someone said you should. The $800/yr cost is real money that compounds.
