董律师:我市某商店今年元月开展有奖销售,我想碰碰运气,花70元钱买条羊绒健美裤售货员给我三张奖卷,抽奖时前两张都没中,而第三张确幸运的中个头奖五千元。当我去领奖时却只给我四千元,我问其原因,商店告诉我要上个人所得税。董律师,商店这样做法对吗?为什么过去中奖都不上税怎么轮到我中奖要上税呢?我十分不理解,请答。影梅 Dong lawyer: a city in January this year, a prize-winning sales, I would like to try my luck, spend 70 dollars to buy a cashmere bodybuilding pants salesman gave me three prize rolls, draw the first two did not, while the third Zhang indeed lucky winner in the first five thousand dollars.
