Is there state tax in California on lottery?

Yes, California does collect tax from California Residents who win lotteries from other states. See Page 4, Line 21 of this State of California Franchise Tax Board document:

Quote: "California excludes California lottery winnings from taxable income." However, "Make no adjustment for lottery winnings from other states. They are

taxable by California."

Federal taxes will be collected on most lottery winnings as well.
