California lottery tax examples
Worked examples for a single filer taking the lump sum in 2026, calculated with the same engine as the calculator above. Cash value is assumed at 48% of the advertised jackpot for illustration — actual cash values vary by lottery and drawing.
| Jackpot | Cash Value | Estimated Federal Tax | Estimated State Tax | Estimated Take-Home |
|---|---|---|---|---|
| $1,000,000 | $480,000 | $131,134 | $0 | $348,866 |
| $10,000,000 | $4,800,000 | $1,726,000 | $0 | $3,074,000 |
| $100,000,000 | $48,000,000 | $17,710,000 | $0 | $30,290,000 |
How California taxes lottery winnings
Under California law, prizes from the California Lottery are excluded from gross income for state tax purposes. That makes California functionally like a no-income-tax state for lottery winners — but only for California Lottery winnings.
The federal picture is unchanged: winnings are ordinary income, taxed at rates up to 37% in 2026. On a big jackpot the federal tax dwarfs everything else, exemption or not.
Cross the border and the deal changes: Oregon (9.90%) and Arizona (2.50%) tax lottery winnings as ordinary income.
Federal taxes on lottery winnings
The federal government taxes lottery winnings as ordinary income — the same category as your salary. For 2026, that means marginal rates from 10% up to 37%, applied after the standard deduction ($16,100 for single filers, $32,200 for married couples filing jointly).
A jackpot-sized win lands almost entirely in the top brackets, which is why the federal tax is usually the largest slice of any prize. Your filing status matters: the same winnings can produce a meaningfully different federal bill for a single filer versus a married couple filing jointly — try both in the calculator above.
Withholding vs. your final tax bill
Federal law requires 24% withholding on lottery winnings over $5,000 — a prepayment against your final federal bill, not the final tax.
Because California Lottery winnings are exempt from state tax, there is no California withholding on them.
Cash option vs. annuity
The annuity pays the advertised jackpot as 30 equal annual payments, each taxed federally in the year received. Spreading payments can keep more of the prize in lower federal brackets.
The California exemption applies to the winnings however you take them — the choice between cash and annuity is a federal-tax and time-value question.
How We Calculate
-
Start with the selected lottery amount. Enter the advertised jackpot and the cash option (or choose the annuity to estimate one annual payment).
-
Determine the cash or taxable amount. For a lump sum, the cash option is the taxable amount. For an annuity, each annual payment is taxed in the year it is received.
-
Apply applicable federal tax rules. Lottery winnings are taxed as ordinary income. The calculator subtracts the standard deduction for your filing status, then applies that year's progressive federal tax brackets.
-
Apply applicable state rules. The calculator applies the state's configured planning rate. States that do not tax lottery winnings show $0 state tax. Local and city taxes are not included.
-
Calculate estimated total tax. Estimated federal and state taxes are added together for the total estimated tax liability.
-
Calculate estimated take-home amount. Estimated total tax is subtracted from the taxable amount. This is an estimate of final liability — withholding shown separately is what may be held back when you are paid, and it is credited against this liability.
Results are estimates for informational purposes only — not tax, legal, or financial advice. Your actual tax bill depends on your full tax return, the lottery's rules, and the laws in effect when you claim the prize.
California lottery tax FAQs
Are lottery winnings taxable in California?
California Lottery winnings are exempt from California individual income tax. Federal income tax still applies to the full amount.
Does the exemption cover out-of-state lottery winnings?
The exemption applies to California Lottery winnings. If you're a California resident with winnings from another state's lottery, consult the Franchise Tax Board's guidance — the calculator above estimates the federal tax either way.
How much federal tax will I owe on California Lottery winnings?
Winnings are federal ordinary income, taxed at 10%–37% for 2026 depending on the amount and your filing status. Use the calculator above for an estimate.
Is 24% withholding the final tax?
No. The 24% federal withholding on winnings over $5,000 is credited against your final tax bill. On a large jackpot your actual federal rate is usually higher, and you'll owe the difference at filing time.
