Winning the lottery can make your dreams come true overnight and jackpot prizes often reach astronomical proportions. Before you receive your prize money, however, government tax collectors may claim their share of the prize. In some lotteries (such as the US Powerball), the advertised jackpots are in the prize amounts before the deduction of taxes, while in other lotteries, no taxes are deducted at all. Even so, you may be subject to local taxation, based on your country of residence. Always check with a tax professional if you come into a large sum of money.
