1099 Tax Calculator for California Freelancers
California is the most expensive state for 1099 contractors when it comes to taxes. With state income tax rates ranging from 1% to 13.3% — the highest in the nation — California freelancers face a significantly larger tax burden compared to those in no-tax states like Texas or Florida.
On top of the 15.3% self-employment tax and federal income tax, a California freelancer earning $100,000 in net business income can expect to pay roughly $6,000-$8,000 in state income tax. This makes tax planning critical: maximizing business expenses, retirement contributions, and the QBI deduction can meaningfully reduce your federal and California taxable income.
