The social security base cannot be adjusted at any time. Because the social security base is calculated according to the average income level of the previous year, if it is adjusted at any time, it will only be returned because the social security base does not match.

Social insurance base, referred to as social insurance base, refers to the social insurance payment base of employees in a social security year. It is determined according to the average monthly wage income of employees from June 1 day to February 1 day in the previous year. The social insurance payment base is an important basis for calculating the social insurance premiums and social insurance benefits paid by employers and their employees. There are upper and lower limits, depending on the actual situation in each region.

There are two ways to adjust the social security base:

1. You can log on to the online social security service platform, find the application for business management, and then enter the name and ID number of the person who changes the base according to the process, and then enter the change base.

2. You can also bring materials that change the base of payment wages to the social security center for adjustment.
