State Gig Tax Guide
California Gig Worker Taxes: The Complete Breakdown
If you drive, deliver, or freelance in California, gig platforms pay you as an independent contractor and withhold nothing. You owe the 15.3% federal self-employment tax and federal income tax — and because California has its own income tax, you also owe state income tax on the same net earnings. Here's how it works and how to keep the bill as low as legally possible.
← Part of the complete Gig Worker Taxes guideHow gig taxes work for California workers
You're an independent contractor — nothing is withheld
Gig platforms pay you as a 1099 contractor, not an employee, so no income or payroll tax comes out of your payouts. You're responsible for setting aside and paying your own taxes.
Federal self-employment tax is 15.3%
That's 12.4% Social Security + 2.9% Medicare on your net earnings — the employer-plus-employee share that a regular job would split with you. It applies in every state, on top of federal income tax.
Federal income tax applies to your net profit
After deductions, your net gig profit is added to your other income and taxed at your federal rate. You can deduct half of your self-employment tax when figuring federal income tax.
Report all income — even without a 1099
You must report every dollar you earn whether or not a platform sends a 1099-NEC or 1099-K. Reporting thresholds for the forms change year to year; your obligation to report does not.
Does California have a state income tax for gig workers?
Yes. California levies a progressive personal income tax, with rates that climb across brackets to roughly 13.3% at the very top (the highest top rate of any state). Most gig workers fall well below the top bracket, but your net gig profit is added to your other California income and taxed at your marginal state rate on top of federal and self-employment tax.
California has no separate self-employment tax — the 15.3% SE tax is federal only — but you still report and pay state income tax on your net earnings. Pay California estimated tax to the Franchise Tax Board (FTB) using Form 540-ES, on a schedule that runs alongside your federal estimates.
App-based rideshare and delivery drivers in California are generally treated as independent contractors under Proposition 22, so platforms continue to issue 1099s rather than W-2s. That means no withholding and full responsibility for your own federal and California taxes.
Remember: the 15.3% self-employment tax is federal and the same in every state — California's income tax is an additional layer on top.
What California gig workers can deduct
Business mileage
Every mile driven while online or on a job, deducted at the IRS standard mileage rate. Usually the single largest deduction — keep a contemporaneous log.
Phone & data
The business-use percentage of your phone and data plan — you cannot accept jobs without it.
Supplies & equipment
Insulated bags, phone mounts, chargers, and other gear bought specifically for the work.
Tolls & parking
Tolls and parking paid while working are deductible (ordinary commuting tolls are not).
You can deduct the IRS standard mileage rate or your actual vehicle expenses — not both. For most drivers the standard mileage rate is simpler and larger. Keep a contemporaneous mileage log either way.
Quarterly estimated taxes
Because no tax is withheld from your payouts, the IRS expects you to pay as you go through quarterly estimated payments rather than one lump sum in April. If you expect to owe $1,000 or more in federal tax for the year, paying quarterly avoids an underpayment penalty.
Federal estimated payments are generally due around April 15, June 15, September 15, and January 15 of the following year. You file your annual federal return by April 15. California expects its own state estimated payments on a comparable schedule — see the state resources below for the exact form and due dates.
Frequently asked questions
Do California gig workers pay state income tax?
Yes. California has a progressive state income tax (with a top rate around 13.3%) that applies to your net gig earnings in addition to federal income tax and the 15.3% federal self-employment tax. You pay California estimates to the Franchise Tax Board using Form 540-ES.
How much should I set aside for taxes in California?
A common rule of thumb is to set aside roughly 25–30% of your net earnings (what's left after mileage and other deductions) to cover the 15.3% self-employment tax, federal income tax, and state income tax. Your exact rate depends on your total household income and your state bracket. Use the Tax Set-Aside calculator for a number tailored to your situation.
Are app-based drivers employees or contractors in California?
Under Proposition 22, app-based rideshare and delivery drivers in California are generally treated as independent contractors, not employees. Platforms issue 1099s, withhold nothing, and you're responsible for your own federal and California taxes.
How do I pay California estimated taxes as a gig worker?
Use California Form 540-ES to pay state estimated income tax to the Franchise Tax Board (FTB), generally four times a year alongside your federal estimates. You can pay online through the FTB's website. This is separate from your federal estimated payments to the IRS.
What can California gig workers deduct?
The biggest deduction is business mileage at the IRS standard mileage rate for every mile driven while working. You can also deduct the business-use share of your phone, supplies and equipment, tolls, and parking. These deductions lower both your federal and your California taxable income.
