The so-called after-tax salary refers to the actual income after deducting personal income tax after deducting five insurances and one gold (including pension insurance, medical insurance, work injury insurance, maternity insurance, unemployment insurance and provident fund) that individuals should pay. Social security and personal provident fund paid by individuals are included in the calculation of pre-tax salary, so after-tax salary is the salary actually paid by the company to employees, and no other expenses need to be deducted.
In short, when you see the salary amount in the recruitment information, it is usually before tax. After employment, your actual income will be calculated according to the above rules, that is, after deducting social security and provident fund, you will pay the corresponding taxes in accordance with personal income tax laws and regulations. So you can know exactly what your after-tax salary is. If you are a domestic resident or have lived continuously for more than one year, the after-tax salary will be the amount you actually get. For non-residents or those who have lived for less than one year, the situation will be different, but the principle is clear.
