Frequently Asked Questions in California
How much tax should a freelancer in California set aside?
In California, freelancers and 1099 contractors should generally reserve 30% to 35% of their gross earnings. This comprehensive reserve covers 15.3% Federal Self-Employment (FICA) tax, roughly 10%–12% effective Federal income tax, and California state income tax (1.0% – 13.3%).
When are California quarterly estimated taxes due and what vouchers are required?
California quarterly estimated payments are administered by the California Franchise Tax Board (FTB) using Form 540-ES. Payments are typically due on April 15, June 15, September 15, and January 15 alongside Federal Form 1040-ES.
What business expenses can I deduct to lower my California freelance taxes?
Legitimate write-offs directly reduce your taxable business profit, lowering both your 15.3% self-employment tax and state/federal income taxes. Top deductions include dedicated home office space, hardware/computers (Section 179), business software, self-employed health insurance premiums under IRC § 162(l), and business vehicle mileage.
What happens if I miss or underpay a quarterly estimated tax deadline in California?
Underpaying or missing a quarterly deadline can result in statutory interest penalties from the IRS and the California Franchise Tax Board (FTB). To avoid penalties, follow the Safe Harbor rule by prepaying at least 90% of your current tax year liability or 100% of your prior year tax liability (110% if your Adjusted Gross Income exceeds $150,000) in four equal quarterly installments.
Should a freelancer in California form an LLC or S-Corporation to save on taxes?
In California, an S-Corp election can save substantial self-employment tax once your net profit exceeds $75,000–$80,000. However, be mindful of California's mandatory $800 annual minimum Franchise Tax Board (FTB) tax and payroll compliance costs.
