If you win the Powerball jackpot, you will have to choose between a cash lump payment or an annuity payment. Each offers advantages: the annuity offers more financial security over a longer period of time, while a lump sum can allow you to use more money in once. At the end of the day, it all depends on the current tax-rate and the use you want to make of the jackpot, so think good about your options and maybe talk to a financial advisor before deciding which option is best for you.
