Can social security cards be used for brothers and sisters?

Social security cards cannot be used by brothers and sisters.

Social security cards cannot be used by brothers and sisters. Because the social security card is registered in real-name registration system, it is only used by the insured, and it is not allowed to lend or fraudulently use other people's social security cards. Fraudulent use of other people's social security cards is an act of stealing, and criminal responsibility may be investigated if the circumstances are serious. However, in some areas, immediate family members may be allowed to use social security cards under certain conditions, but this needs to be in line with local specific policies.

What does the social security contribution base mean?

Social security payment base refers to the social insurance payment base of employees in a social security year. The social security payment base will be determined according to the average monthly income tax declared by employees in the previous year, which is an important basis for paying social security.

After the same payment year is determined, the social security payment base cannot be changed. February to May of each year is the time to declare the social security base of the next settlement year.

There are upper and lower limits on the social security payment base. The upper limit means that the part whose salary exceeds 300% of the average monthly salary of employees in the previous year is not included in the social security base. The lower limit means that if the salary is lower than 60% of the average monthly salary of employees in the previous year, 60% of the average monthly salary of employees in the previous year will be used as the social security base.
