How to calculate the inter-annual payment base of social security?

Dear ~ Hello, it's my pleasure to answer your question. According to your question, the following is the result of my analysis for you from the legal point of view: how to calculate the inter-annual payment base of social security: generally, my salary income in the previous year is the payment base. (1) If the wage income of employees is higher than the local average wage of employees in the previous year of 300, the payment base shall be 300 of the local average wage of employees in the previous year; (two) the wage income of employees is lower than the local average wage of employees in the previous year of 60, and the payment base is the local average wage of employees in the previous year of 60; (3) If the employee's salary is between 30,060, it shall be declared according to the facts. When it is impossible to determine the wage income of employees, the payment base shall be determined according to the local average wage of employees in the previous year published by the local labor administrative department. Social security will regularly check the base every year (March or July, in different places), and declare a new base according to the average monthly salary of employees in the previous year. It is necessary to prepare proof of these payroll.
