How should Yizhang Social Security Bureau purchase social security at one time?

It can't be paid in one lump sum. According to "People's Republic of China (PRC) Social Insurance Law", when an individual participating in the basic old-age insurance for employees reaches the statutory retirement age, if the accumulated payment is less than 15 years, the payment can be extended to 15 years. Before the implementation of the social insurance law, if the insured person is still less than 15 years after the extension of payment for 5 years, he can pay in one lump sum until it reaches 15 years.

Individuals who participate in the basic old-age insurance for employees have reached the statutory retirement age and paid less than 15 years, and can apply for the new rural social endowment insurance or urban social endowment insurance where their household registration is located, and enjoy the corresponding old-age insurance benefits.

Individuals who participate in the basic old-age insurance for employees have reached the statutory retirement age, and the accumulated payment is less than 15 years, and they have not been transferred to the new rural social endowment insurance or urban residents' social endowment insurance. Individuals can apply in writing to terminate the basic old-age insurance relationship for employees. After receiving the application, the social insurance agency shall inform it in writing of its right to transfer to the new rural social endowment insurance or urban residents' social endowment insurance and the consequences of terminating the basic endowment 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.

Secondly, the employer takes the initiative to handle one-time payment for employees. The payment standard of each time period is calculated according to the payment base and payment proportion of the corresponding time period determined in each year (if there is no payment base and proportion in that year, it shall be implemented according to the quota standard of that year).

The one-time payment standard of social security varies from place to place. I suggest you call the social security number 12333 for consultation!
