Can the social security paid in Beijing be refunded? How should I handle the refund?

There is no way to apply for a refund.

According to the "Social Security Law": Article 14 Individual accounts shall not be withdrawn in advance, and the bookkeeping interest rate shall not be lower than the bank time deposit interest rate, and interest tax shall be exempted. If an individual dies, the balance of the individual account can be inherited.

Sixteenth individuals who participate in the basic old-age insurance will receive the basic old-age pension on a monthly basis if they have paid for fifteen years at the statutory retirement age.

According to "Several Provisions on Implementing the Social Insurance Law of People's Republic of China (PRC)", Article 6 Individual accounts of employees' basic old-age insurance shall not be withdrawn in advance. Individuals who leave the country to settle down before reaching the legal conditions for receiving the basic pension shall keep their personal accounts and enjoy the corresponding pension insurance benefits in accordance with state regulations when reaching the legal conditions for receiving the basic pension. Among them, those who lose their nationality in People's Republic of China (PRC) may apply in writing to terminate the basic old-age insurance relationship for employees when leaving the country or after leaving the country. After receiving the application, the social insurance agency shall inform it in writing of its right to keep personal accounts and the consequences of terminating the basic old-age insurance relationship for employees. After my written confirmation, I will terminate the employee's basic old-age insurance relationship and pay me the amount stored in my personal account in one lump sum.

After the death of an individual who participates in the basic old-age insurance for employees, the balance in his personal account can be fully inherited according to law.
