citizens are subject to an initial federal tax payment of 30 percent rather than 24 percent. If you win the jackpot you will be subject to the top federal tax rate of 37 percent. You may then be eligible for a refund or have to pay more tax when you file your returns, depending on your total income.
A federal tax of 24 percent will be taken from all prizes above $5,000 (including the jackpot) before you receive your prize money.
