California LLC Costs: Franchise Tax, Gross Receipts Fee, and Filing
Every California LLC owes a minimum annual franchise tax of $800 to the Franchise Tax Board (FTB), due on the 15th day of the 4th month after formation and annually thereafter. New LLCs formed after January 1, 2024 are exempt from this fee for their first tax year only if annual revenue is below $250,000. The $800 applies regardless of whether the LLC earns any income -- even dormant LLCs owe it.
LLCs with California gross receipts exceeding $250,000 owe an additional LLC fee (gross receipts fee) based on total California revenue. This fee is separate from and in addition to the $800 franchise tax. The LLC formation filing fee with the Secretary of State is $70, and the biennial Statement of Information costs $20 (due within 90 days of formation, then every 2 years).
| Gross Receipts | LLC Fee | Total Annual (w/ $800 franchise) |
|---|---|---|
| Under $250,000 | $0 | $800 |
| $250,000 - $499,999 | $900 | $1,700 |
| $500,000 - $999,999 | $2,500 | $3,300 |
| $1,000,000 - $4,999,999 | $6,000 | $6,800 |
| $5,000,000+ | $11,790 | $12,590 |
Liability Protection: When an LLC Is Worth the Extra Cost
The primary advantage of a California LLC is limited liability protection. LLC members' personal assets -- home, savings, personal vehicles -- are generally shielded from business debts and lawsuits. A sole proprietor has no legal separation between personal and business assets; a $100,000 judgment against the business can attach to the owner's personal bank account, home equity, and other property.
Liability protection is most valuable for businesses with physical products (product liability exposure), commercial leases (personal guarantee may still be required but limits additional exposure), employees or contractors (employment lawsuits), and client-facing professional services (errors and omissions claims). The average cost of a small business lawsuit is $75,000-$150,000 in legal fees alone, even when the business prevails.
However, an LLC's protection is not absolute. California courts can pierce the corporate veil if the LLC is treated as an alter ego of the owner -- meaning commingled funds, inadequate capitalization, failure to maintain an operating agreement, or using the LLC to perpetrate fraud. To maintain protection, keep separate bank accounts, maintain a written operating agreement, file all required state documents, and hold the LLC out as a distinct entity in all contracts and dealings.
Tax Treatment: Both Structures Pay Self-Employment Tax
A critical fact often overlooked: single-member LLCs and sole proprietorships pay identical federal taxes. Both are disregarded entities for federal tax purposes, reporting income on Schedule C of the owner's personal return. Both pay self-employment tax of 15.3% (12.4% Social Security on earnings up to $176,100 in 2026, plus 2.9% Medicare on all earnings). The LLC structure alone provides zero federal tax savings.
To achieve tax savings, an LLC can elect to be taxed as an S-Corporation by filing Form 2553. This allows the owner to pay themselves a "reasonable salary" (subject to FICA) and take remaining profits as distributions not subject to self-employment tax. An LLC taxed as an S-Corp earning $100,000 in profit with a $60,000 reasonable salary saves approximately $6,120 annually in SE tax on the $40,000 distribution. This strategy typically becomes beneficial when profit exceeds $50,000-$60,000.
California adds a 1.5% net income tax on S-Corps (minimum $800), making the S-Corp election slightly more expensive at the state level. The combined federal SE tax savings minus the additional California tax determines the net benefit. An LLC earning $80,000+ in profit in California generally saves $3,000-$8,000/year with the S-Corp election after accounting for the added cost of payroll administration ($500-$1,500/year).
