纳税公式为:(月工资金额-3500)*对应税率-速算扣除数
假如某员工月发金额为5500元,其纳税金额为:
年终奖纳税规则:
1、发放年终奖的当月工资高于3500元时,年终奖扣税方式为:年终奖*税率-速算扣除数,税率是按年终奖/12作为“应纳税所得额”对应的税率。
2、当月工资低于3500元时,年终奖个人所得税=(年终奖-(3500-月工资))*税率-速算扣除数,税率是按年终奖-(3500-月工资)除以12作为“应纳税所得额”对应的税率。
(规则2可不遵守,主要满足规则1即可,因为涉及纳税都是工资高的,工资低的可忽略)
假如某员工年终奖为6.6万,起纳税为:
先判断纳税等级,即66000/12=5500元(在纳税等级第二等级),故纳税金额为:
最想要的效果是假如此人年薪要求税后100万,该如何设置其月发和年终奖金额?(税后100万,就要将纳税金额考虑在工资范围内)
