How to determine the social security base after arriving at a new unit?

Legal analysis: According to national regulations, the base for employees to pay endowment insurance is based on their average salary in the previous year. However, due to the transfer to a new work unit, it is impossible to calculate the average monthly salary of the previous year. I can temporarily take the salary transferred to the month as the payment base, and when I adjust the payment base next year, I will take the average monthly salary of the previous year as the base.

Legal basis: Article 4 of the Social Insurance Law of People's Republic of China (PRC) * * * 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 ask social insurance agencies to provide social insurance consultation and other related services. Individuals enjoy social insurance benefits according to law and have the right to supervise the payment of their own units.
