Estimates assume the top federal bracket (37%) on the full prize, which is close to reality for jackpots and conservative for smaller prizes. Local taxes, deductions, and filing status change the exact number. This is education, not tax advice.
Quick Answer
Quick Answer: How California Taxes Lottery Winnings
California is the special case: by statute, California Lottery prizes are exempt from California income tax, even though the state taxes most other income at up to 13.3%. The lottery withholds 24% federal tax on prizes over $5,000, and big winners owe up to 37% federally at filing. Out-of-state lottery prizes do NOT get the exemption.

Withholding Is Not the Bill
On any prize over $5,000 the lottery sends 24% straight to the IRS before you see a dollar. A large prize, however, lands mostly in the 37% federal bracket, so the true federal bill runs well past what was withheld. In California the state layer disappears for California Lottery prizes by statute, so the planning problem is purely federal, unless you won in another state. Winners who spend to the post-withholding number get an ugly surprise in April. Set the difference aside the week you claim.
Claiming Rules That Matter in California
The claim window is 180 days from the draw date; Powerball and Mega Millions jackpots get 1 year from the draw date. For the cash-versus-annuity decision: jackpot winners choose cash vs annuity on a notarized Jackpot Election Payment Form within 60 days of claim approval; defaults to annuity if not returned. Anonymity: not anonymous - winner's full name and retailer location are public record; CA Lottery prizes are exempt from CA income tax (Gov. Code 8880.68) but federal tax applies.
