California LLC Fee 2026: Tiers, June 15 Estimate & Penalty
Two charges trip up California LLC owners every year: the $800 annual tax everyone knows about, and the income-based California LLC fee that catches many by surprise. The fee can run as high as $11,790, it’s based on gross income (not profit), and the estimate is due mid-year — well before the return. This guide covers who owes it, the exact tiers, the June 15 estimate, and how to sidestep the 10% underpayment penalty.
At SW Accounting & Consulting Corp, we manage California entity compliance for Los Angeles area LLCs across every industry. Below: the $800-tax-vs-fee distinction, the fee tiers, the gross-income trap, deadlines, and the prior-year safe harbor.
The $800 tax vs. the LLC fee — two different charges 🪙
California LLCs face two separate annual obligations. Don’t confuse them — they’re computed differently, due at different times, and paid on different forms.
| $800 Annual Tax | LLC Fee (§17942) | |
|---|---|---|
| Who owes it | Every CA LLC (flat minimum) | Only LLCs with total CA income ≥ $250,000 |
| Amount | $800 flat | $900 – $11,790, tiered by income |
| Based on | Existence/doing business | Total California income (gross, not net) |
| Estimate due | 15th day of 4th month (generally) | June 15 (calendar year) — Form 3536 |
Both apply to single-member LLCs and LLCs taxed as partnerships alike. This post focuses on the income-based fee — the one that surprises people.
Who owes the LLC fee, and how much? 💵
An LLC organized, doing business, or registered in California owes the fee if its total income from all sources derived from or attributable to California is at least $250,000. The fee is tiered:
| Total California income | LLC fee |
|---|---|
| $250,000 – $499,999 | $900 |
| $500,000 – $999,999 | $2,500 |
| $1,000,000 – $4,999,999 | $6,000 |
| $5,000,000 or more | $11,790 |
Below $250,000 of California income, no fee applies (you still owe the $800 annual tax).
“Total California income” for the fee means GROSS income plus the cost of goods sold paid or incurred in the trade or business — NOT net profit. A low-margin business with $5 million of revenue and razor-thin profit still pays the top $11,790 fee. Many owners budget off net income and get blindsided. Calculate the fee off gross receipts (plus COGS), not your bottom line.
When is it due, and on what form? 📅
The ESTIMATED LLC fee is due by June 15 for calendar-year LLCs (the 15th day of the sixth month of the taxable year for fiscal-year LLCs), well before the return is filed. Use Form 3536 (Estimated Fee for LLCs) or FTB Web Pay.
Because the fee is estimated mid-year, you’re projecting your full-year California income before the year is over — which is exactly why penalties happen. Build the estimate carefully and revisit it if a big contract lands later in the year.
How do you avoid the 10% penalty? 🛡
If the estimated fee paid by the due date is late or less than the amount owed, FTB assesses a 10% penalty on the underpaid fee (the difference between the actual current-year fee and what you paid on time). But there’s a clean safe harbor.
- Prior-year safe harbor — pay an estimated fee equal to or greater than your PRIOR year’s LLC fee by the due date, and the underpayment penalty does not apply — even if your current-year fee turns out higher.
- No 12-month requirement — the prior tax year doesn’t need to have been a full 12 months to use the safe harbor.
- First-year exemption — there’s no estimated-fee penalty for an LLC’s first year filing in California.
The simplest way to never owe the penalty: pay at least last year’s LLC fee by June 15. If you grew and your actual fee is higher, you settle the difference with the return — penalty-free. If you’re in a growth year and expect to jump a tier, matching last year’s fee protects you from the 10% even though you’ll owe more at filing.
Frequently asked questions about the California LLC fee
No. The $800 annual tax is a flat minimum every CA LLC owes. The LLC fee (R&TC §17942) is a separate, income-based charge ($900–$11,790) that applies only when total California income reaches $250,000.
Revenue. “Total California income” for the fee is gross income plus cost of goods sold attributable to California — not net profit. A high-revenue, low-profit LLC can owe the top fee.
June 15 for calendar-year LLCs (15th day of the sixth month for fiscal-year LLCs), paid with Form 3536 or via Web Pay. The balance is reconciled when you file the LLC return.
Pay at least your prior-year LLC fee by the due date — that safe harbor blocks the penalty even if the current-year fee is higher. First-year LLCs have no estimated-fee penalty.
