California LLC vs. S-Corp: The True Cost Comparison

In California, the LLC vs. S-corp decision is more expensive than in other states. The S-corp pays 1.5% franchise tax on net income instead of the flat $800 LLC fee. Here's when the S-corp still wins — and when it doesn't.

Key Takeaways

  • A California LLC pays a flat $800 annual franchise fee regardless of income. A California S-corp pays 1.5% of net income, with a minimum of $800.
  • An LLC does not reduce self-employment tax — you pay 15.3% on 100% of net profit either way as a sole prop or single-member LLC.
  • An S-corp reduces SE tax by splitting income between a W-2 salary (subject to SE tax) and distributions (not subject to SE tax). That's the entire tax case for the S-corp election.
  • The S-corp break-even in California is higher than in other states because of the 1.5% franchise tax. The general threshold is around $60,000–$80,000 in net profit, depending on salary assumptions.
  • The S-corp adds real costs: payroll setup (~$600/year), a separate S-corp return (Form 1120-S, ~$900+ more at filing time), and the 1.5% CA franchise tax. Model these before electing.

California adds a wrinkle most national comparisons miss

Most “LLC vs. S-corp” guides are written for a national audience. In California, the S-corp pays 1.5% of net income as a state franchise tax — not a flat $800 like the LLC. At $200,000 in net income, that’s $3,000/year in additional state tax. The S-corp can still win, but the break-even is higher than it is in most other states.

What an LLC actually does (and doesn’t do)

An LLC provides liability protection — it separates your personal assets from business debts and legal claims. That’s its primary function.

By itself, an LLC does not reduce taxes. A single-member LLC is taxed as a sole proprietorship by default. You report income on Schedule C. You pay self-employment tax (15.3%) on 100% of net profit. The LLC filing fee with the California Secretary of State is $70. The annual LLC franchise fee is $800.

If someone told you that “forming an LLC” would save you on taxes, they may have been referring to the S-corp election — which is a separate decision.

What an S-corp actually does

An S-corp is a tax classification. You can elect S-corp status for a corporation or for an LLC (under IRC §1361). The key mechanic: as an S-corp owner, you split income into W-2 salary and distributions.

  • W-2 salary: subject to payroll taxes (Social Security + Medicare, approximately 15.3% combined)
  • Distributions: not subject to payroll taxes

The savings come from the portion of income paid as distributions — it bypasses SE tax. If you make $200,000 in net profit and take $80,000 as salary and $120,000 as distributions, you’re paying SE tax on $80,000 instead of $200,000. At 15.3%, that’s a meaningful difference.

The California S-corp franchise tax

Here’s the California-specific wrinkle. California charges S-corps a franchise tax of 1.5% of net income, with a minimum of $800. An LLC pays a flat $800 regardless of income. So:

S-corp franchise tax vs. LLC at different income levels
Net income: $50,000LLC: $800 | S-corp: $800 (min)
Net income: $100,000LLC: $800 | S-corp: $1,500
Net income: $200,000LLC: $800 | S-corp: $3,000
Net income: $400,000LLC: $800 | S-corp: $6,000

The S-corp pays $2,200 more than the LLC at $200,000 in net income. That cost is offset by SE tax savings — but it raises the break-even point.

The real break-even calculation

To determine whether an S-corp saves money in California, you compare:

  • SE tax savings (15.3% × the distribution portion of income)
  • minus: incremental CA franchise tax (1.5% × net income − $800)
  • minus: payroll service cost (~$600/year)
  • minus: incremental return cost (~$900 for the separate 1120-S)

In California, the S-corp generally starts making financial sense at roughly $60,000–$80,000 in net profit. Below that threshold, the additional costs exceed the SE tax savings. At $150,000+, the savings are typically substantial enough that the election is worth doing.

What the calculator shows you

The CA Entity Cost Planner at https://www.reesetaxwealth.com/tools/california-entity-cost-planner runs this math with your actual numbers. You enter net profit and a salary assumption, and it shows the all-in annual cost for each structure — including the CA franchise tax, payroll costs, and the net SE tax savings. It also shows a recommendation based on where the break-even falls.

Frequently asked

Questions owners actually ask

Does forming an LLC reduce my taxes in California?
No, not directly. An LLC is a legal structure — it doesn't change how your income is taxed by default. A single-member LLC is taxed as a sole proprietorship. A multi-member LLC is taxed as a partnership. In both cases, you still pay self-employment tax on 100% of net profit. The LLC adds liability protection; it doesn't add tax savings.
When does an S-corp election make sense in California?
The S-corp saves money when the SE tax savings from splitting income between W-2 and distributions exceed the additional costs: 1.5% CA franchise tax, payroll service fees, and the cost of a separate business return. In California, that break-even is typically around $60,000–$80,000 in net profit, depending on what salary percentage your CPA recommends.
Why is California's S-corp tax higher than other states?
California taxes S-corps at 1.5% of net income as a state franchise tax. Most states don't charge this — they simply pass through to the owner's personal return. So an S-corp making $200,000 in California owes $3,000 in franchise tax that a comparable S-corp in, say, Texas or Nevada would not owe. This narrows the advantage but rarely eliminates it at meaningful income levels.
What's the minimum tax an S-corp pays in California?
The minimum California franchise tax for an S-corp is $800 — the same as an LLC. At low income levels (under $53,333 in net income), the S-corp franchise tax stays at $800, exactly matching the LLC. Above that threshold, 1.5% × net income exceeds $800 and the S-corp pays more.
Can I convert my LLC to an S-corp in California?
Yes. The most common approach is to elect S-corp status for an existing LLC by filing Form 2553 with the IRS (by March 15 for the current tax year, or within 75 days of formation for a new entity). The LLC doesn't need to be dissolved or replaced — you're electing how it's taxed, not changing the legal structure. California recognizes the federal S-corp election.
Does the PTET election apply to S-corps in California?
Yes. California's Pass-Through Entity Tax (PTET) applies to S-corps and partnerships. It allows the entity to pay California income tax at the entity level, bypassing the SALT cap ($40,400 for 2026 under OBBBA, phasing down above $505k income) on the owner's personal return. The owner gets a California credit so there's no double taxation. For an S-corp owner already paying the 1.5% franchise tax, the PTET is an additional (and separate) tax planning tool.
