Funded trader taxes in California

Updated October 30, 2026 · For the 2026 tax year

California taxes prop firm payouts as ordinary income, in graduated brackets. Your payout stacks on top of your wages. It also has an estimated payment schedule that doesn't match the federal one.

How the calculator handles California

It uses the 2026 Schedule X brackets from the Franchise Tax Board (FTB), which run from 1% to 12.3%. A 1% Behavioral Health Services Tax applies to taxable income over $1,000,000. The single standard deduction is $5,900. The deductible half of self-employment tax lowers your California income too.

Your exemption credit is left out because it's the same with or without the payout, so it doesn't change the tax caused by the payout. The calculator has no local tax line for California.

FTB says the complete 2026 figures come out in late December, so check back after that.

Worked example: $5,000 payout on top of a $70,000 job

A single filer in California with $70,000 of W-2 wages, one $5,000 payout in 2026 and no trading costs. These are the calculator's numbers for October 30, 2026.

The lines can differ from the total by a cent, because the calculator rounds only at the end. It leaves out the QBI deduction, which may lower the federal tax.

Here's the California line by hand:

• Wages only: $70,000 minus the $5,900 deduction is $64,100 of taxable income.
• With the payout: add $5,000 and subtract $353.24 (half of self-employment tax). That's $68,746.76.
• The $4,646.76 increase sits in the 8% bracket, which runs from $59,498 to $75,197. That gives $371.74.

If your taxable income is above $75,197, the next dollars are taxed at 9.3%. With $120,000 of wages instead, the same $5,000 payout adds $432.15 of California tax. Compare the other states on the Texas page.

California's estimated payments are uneven

You generally must make California estimated payments if you expect to owe at least $500 for 2026 after withholding and credits ($250 if married or RDP filing separately), and your withholding and credits will be less than the smaller of 90% of your 2026 tax or 100% of your 2025 tax. The installments, from FTB's 2026 Form 540-ES instructions:

The federal schedule is four equal parts, so don't copy your federal amounts over. PayoutTax's quarterly amounts cover federal tax only.

In the example, $371.74 is under the $500 line. If your withholding covers the tax on your wages, that one payout wouldn't reach it. With this wage, payouts of about $6,700 would.

If you file your 2026 return by January 31, 2027 and pay the whole balance, you don't have to make the last payment. That's a day earlier than the federal February 1 rule. Higher earners have stricter rules: above $150,000 of 2025 California AGI ($75,000 if married or RDP filing separately), the prior-year figure is 110%.

Raising withholding: use the DE 4

If you have a day job, FTB says more withholding could remove the need for a large payment with your return. For California, use EDD Form DE 4. It isn't the same as the federal W-4, and it changes only your California withholding.

Two California details to raise with your CPA

• The $800 LLC tax. FTB says every LLC doing business or organized in California must pay an annual tax of $800, even with no business activity, until it's canceled. An LLC that makes more than $250,000 also pays a fee. See our LLC guide.
• Contractor status. FTB notes that you can be a contractor for federal purposes and an employee for California purposes. The half-of-self-employment deduction isn't allowed to an employee. The calculator assumes you're a contractor for both.

This example is an estimate for one situation. Your numbers will differ. Not tax advice; confirm with a CPA.
