Can the company upgrade the employee's second social security to a higher level?

Legal analysis: the second grade of social security can be changed into the first grade, yes.

The social security payment base is determined according to the local social wages in the previous year. The payment range is 60%-300%, depending on the economic situation.

When the company declares the payment list and payment base every month, it only needs to change the value on the payment base, change the second file to the first file, and affix the official seal of the company after being audited by the Social Security Bureau. Then take this declaration form to pay the fee.

Legal basis: Article 4 of People's Republic of China (PRC) Social Insurance Law. Employers and individuals in People's Republic of China (PRC) pay social insurance premiums according to law, and have the right to inquire about payment records and personal rights and interests records, and require social insurance agencies to provide social insurance inquiry and other related services. Individuals enjoy social insurance benefits according to law and have the right to supervise the payment of their own units.
