1、税后工资倒推税前工资
=MAX((A1-5*{30,142,482,782,1182,1782,3482})/(1-{3,10,20,25,30,35,45}%),IF(A1="",0,A1))
其中A1为税后工资单元格
2、由缴纳个税金额反算出税前工资
=MIN((A1+{0;210;1410;2660;4410;7160;15160})/{0.03;0.1;0.2;0.25;0.3;0.35;0.45})+5000
其中A1为个税金额单元格
3、由税前工资计算个税金额
=5*MAX(A1*{0.6,2,4,5,6,7,9}%-{30,142,482,782,1182,1782,3482},0)
其中A1为税前工资单元格
