In 2014, you can buy pension insurance with a one-time payment of 48,000 yuan, which is a unified policy across the country.

In 2014, the Ministry of Human Resources and Social Security issued a document, namely, the "Notice of the Ministry of Human Resources and Social Security and the Ministry of Finance on Further Strengthening the Management of the Revenue and Expenditure of Enterprise Employees' Basic Pension Insurance Funds." After the document was issued, all provinces, municipalities, autonomous regions, and municipalities directly under the Central Government respectively responded to this document.

Implementation measures have been formulated based on the actual situation in the region. The overall spirit is that flexible employment personnel are not allowed to increase their payment years through one-time back payment.

The door to one-time back payment starting in 2019 has basically been closed.
