After winning the Powerball jackpot, you will be given the choice between scooping the prize as a cash lump payment or as an annuity payment over 30 years. Both options are attractive but the main difference is that the annuity offers more financial security over longer while with the lump sum payment you will get more money in once. If you scooped the biggest Powerball prize, we advise you to contact a financial advisor before making any decision.
