<P> Almost all prizes must be claimed within 180 days of the draw or the announced end of the game .

Any unclaimed prize money is transferred to the education fund in addition to the minimum 34% that the Lottery is already obligated to transfer from income . </P> <P> Because many of the 44 Mega Millions participants have a one - year claim period, the California legislature changed the language in the Lottery Act . On April 23, 2008, Gov. Arnold Schwarzenegger signed Assembly Member Van Tran's Assembly Bill 1251, modifying California Government Code section 8880.321 to allow for a one - year claim period for a Mega Millions jackpot prize .

Merchandise prizes over $5,000 are subject to 33% Federal withholding . Scratchers tickets are generally one - payment prizes; however, some games have annuity options for payments each year, or per week .

For SuperLotto Plus and Mega Millions jackpots, the player may choose a single cash payout for a floating percentage of the jackpot, or an annuity . The SuperLotto Plus, Mega Millions, and Powerball payment schedule are on a graduated basis over 30 annual payments . Until 2005, when California joined Mega Millions, the payment choice on SuperLotto Plus had to be made when the ticket was bought . Since then, there is a 60 - day window after winning, in which the choice of cash or annuity is to be made . </P> <P> Unclaimed prizes remaining after the claim period expires always go to supporting California's public schools . As of the end of FY 2013--14, a total of $793.5 in unclaimed prizes have been awarded to education . </P>
