What does the sum of payment bases mean?

Legal analysis: the social security payment base refers to 60%-300% of the average social wage as the payment base. For example, the average social wage 10000 yuan, and the payment base can be 600 yuan -3000 yuan. Social security will check the base at a fixed time every year (March or July, which varies from place to place), and declare a new base according to the average monthly salary of employees in the previous year. The base for the insured unit to pay the basic old-age insurance premium can be the total wages of employees, or the sum of the individual total wage base of the employees of this unit, but it should be unified in the whole province as an approved method.

Legal basis: Article 90 of People's Republic of China (PRC) Social Insurance Law. If the social insurance premium collection agency arbitrarily changes the base and rate of social insurance premium payment, resulting in underpayment or overpayment of social insurance premium, the relevant administrative department shall order it to recover the social insurance premium that should be paid or refund the social insurance premium that should not be paid; The directly responsible person in charge and other directly responsible personnel shall be punished according to law.
