Freelancer Tax Overview

Freelancers — independent contractors, consultants, gig workers, and self-employed professionals — face a more complex tax situation than W-2 employees. You are responsible for paying both income tax and self-employment tax (15.3% on net earnings), making quarterly estimated tax payments, tracking deductible business expenses, and filing a California return in addition to your federal return. The upside: freelancers have access to deductions that W-2 employees cannot claim, and with proper planning, can significantly reduce their effective tax rate.

Quarterly Estimated Taxes

Freelancers must make quarterly estimated tax payments to avoid underpayment penalties. The federal due dates are April 15, June 15, September 15, and January 15. California has the same due dates but a different payment schedule (30% Q1, 40% Q2, 0% Q3, 30% Q4). KDA calculates the correct quarterly payment for every freelance client — underpaying is costly, but overpaying means you've given the government an interest-free loan.

California Freelancer Taxes

California freelancers pay California income tax on all net business income at rates up to 13.3%. California does not have a preferential rate for self-employment income. California also requires freelancers who form LLCs to pay the $800 minimum franchise tax plus the LLC annual fee based on gross receipts. For freelancers with gross receipts under $250,000, the LLC provides liability protection at a cost of only $800 per year in franchise tax.

Should You Form an LLC or S Corp?

For freelancers with net profit under $50,000, operating as a sole proprietor (no entity) is often the simplest and most cost-effective approach. For net profit between $50,000 and $100,000, an LLC provides liability protection with minimal additional tax cost. For net profit over $100,000, an S corp election typically saves more in SE taxes than it costs to maintain — KDA models the exact breakeven for each client's situation.

Record-Keeping for Freelancers

KDA's minimum record-keeping requirements for freelancers: (1) Separate business bank account — never mix personal and business expenses. (2) Receipts for all business expenses — use a receipt scanning app. (3) Mileage log — maintained daily, not reconstructed at year-end. (4) Invoices and contracts — keep all client agreements and invoices. (5) 1099s received — reconcile against your own records. (6) Home office measurements — take photos and measure the dedicated space. These records must be kept for at least 7 years.

Frequently Asked Questions

Common Questions About Freelancer Tax Guide California

Do I need to send 1099s to the people I pay?
If you pay any individual or unincorporated business $600 or more in a calendar year for services, you must issue Form 1099-NEC by January 31 of the following year. You do not need to issue 1099s to corporations (with some exceptions) or for payments made via credit card or PayPal (the payment processor handles those).
Yes, but only the business-use percentage. If you use your home internet 60% for business, you can deduct 60% of the monthly cost. The same applies to your cell phone. Keep records of how you calculated the business-use percentage.
The Section 199A QBI deduction allows eligible self-employed individuals to deduct up to 20% of qualified business income. Most freelancers qualify, but there are income phase-outs and limitations for "specified service trades or businesses" (SSTBs) — which include attorneys, accountants, consultants, and financial advisors. KDA evaluates QBI eligibility for every freelance client.
