How to calculate social insurance when civil servants transfer to enterprises? Is there any specific red tape?

1. According to "Reply on Pension Insurance after Resignation and Dismissal of Civil Servants":

If a civil servant participates in the basic old-age insurance for enterprise employees after resigning, dismissal and re-employment, the continuous length of service in the original employer before resignation and dismissal can be calculated as the payment period, which is combined with the actual payment period.

So after you resign, your company can register the basic social endowment insurance for you, and then you can take your civil servant's work file to two confirmation offices of the local social security center to confirm the original length of service as the payment period.

2. After resigning, if you are no longer a civil servant, you can start to participate in social insurance and pay five insurances and one gold to a new unit or personal file custodian. The previous medical care for civil servants will definitely be gone, but the length of service of civil servants can be converted, which is regarded as the payment period in the endowment insurance of social insurance. The specific procedures will be asked by the local social security agency.
