After-tax wages are obtained by deducting five insurances and one gold (individual contributions) from pre-tax wages and then subtracting individual taxes, that is, pre-tax wages-personal income tax = after-tax wages. After-tax salary is what some people call "hand-held salary", but it is actually the salary on arrival. Suppose 800 yuan has five insurances and one gold, the tax payable =8000 -5000 yuan -800 yuan =2200 yuan, and the tax payable =2200*3%-0=66 yuan, then the after-tax salary =8000-800-66=7 134 yuan.
