Can I pay social security for part-time jobs?

You can't. According to Fage's inquiry, there is no need to pay social security for part-time jobs. Part-time workers do not engage in their own jobs or sign labor contracts, but they can sign part-time agreements or other contracts without paying social insurance. Part-time job refers to the use of spare time to engage in a second job without leaving your job; Signing a labor contract to pay social insurance will inevitably lead to repeated payment of old-age insurance, which is not allowed by the state and conflicts with the social insurance policy. Therefore, no matter whether students work part-time or have gone out to work part-time, they do not need to pay social security, because repeated payment of social security is not allowed.
