Self-employed Californians face a quadruple tax hit: federal self-employment tax (15.3%), federal income tax (up to 37%), California income tax (up to 13.3%), AND the $800 minimum franchise tax for LLCs. On top of that, LLCs with gross revenue over $250,000 pay additional LLC fees ($900-$11,790). A freelancer netting $150,000 in California keeps roughly 55-58 cents of every dollar earned. This calculator breaks down every tax layer for sole proprietors and single-member LLCs.

Frequently Asked Questions
What is California's $800 LLC franchise tax?
Every LLC registered in California must pay an $800 minimum franchise tax annually to the Franchise Tax Board (FTB), regardless of income — even if the LLC made $0. This is due by the 15th day of the 4th month after forming.
What are the additional California LLC fees?
LLCs with gross revenue over $250,000 pay additional fees: $900 ($250K-$500K), $2,500 ($500K-$1M), $6,000 ($1M-$5M), and $11,790 ($5M+). These are based on GROSS revenue, not net profit.
Should I form an S-Corp in California?
An S-Corp can save significant self-employment tax by splitting income into salary and distributions. However, CA charges a 1.5% net income tax on S-Corps (minimum $800). Generally beneficial if net income exceeds ~$80,000-$100,000.
Do I pay SDI as self-employed in California?
Self-employed individuals can elect into SDI coverage but are not required to pay it. If you opt in, the rate is 1.1% on net self-employment income. This provides access to CA disability and paid family leave benefits.
Is the $800 franchise tax waived for new LLCs?
California waived the first-year $800 franchise tax for new LLCs formed between 2021-2023. Check current FTB guidance to see if this waiver has been extended. Starting in year 2, the $800 minimum always applies.
