What does it mean to increase the base of social security contributions?

Legal analysis: the social security payment base is related to wages, but sometimes it is not completely linked to wages. Every year comes a new payment year, usually around August. Due to the announcement of the average monthly salary of employees in the previous year, the social security payment base is linked to the average monthly salary of employees in the previous year. The average monthly salary of employees in the previous year basically increased every year. As long as the average monthly salary of employees in the previous year increases, the payment base will increase.

Legal basis: Article 2 of the Social Insurance Law of People's Republic of China (PRC) The state establishes social insurance systems such as basic old-age insurance, basic medical insurance, industrial injury insurance, unemployment insurance, maternity insurance, etc., to protect citizens' right to get material help from the state and society according to law in case of old age, illness, industrial injury, unemployment and maternity.
