You can pay by yourself. According to Article 58 of Chapter VII of the Social Insurance Law of the People's Republic of China, 1. Individual businesses without employees who voluntarily participate in social insurance, part-time employees who do not participate in social insurance in the employer, and other flexible employees shall apply to the social insurance agency for social insurance registration. 2. After resignation, the party concerned can participate in the pension insurance and medical insurance for flexible employees and pay on schedule (as for the payment frequency, it shall be subject to the local social security regulations). 3. Individual contribution amount of pension insurance for flexible employees=payment base * 20%, and individual contribution amount of medical insurance=payment base * 8~9%. Among them, the payment base is freely selected by the parties within the limits of local social security. 4. After participating in the social insurance for flexible employment personnel, the payment duration and individual account balance before and after are calculated cumulatively. Then let's extend this question: if you haven't found a job after leaving the company, you can pay social insurance by yourself, but you can only pay endowment insurance+medical insurance (or choose to pay only endowment insurance, but if you want to pay medical insurance, you must add endowment insurance), work-related injury, maternity, unemployment, provident fund, You can't hand it in personally. If an individual pays, he/she can take his/her ID card and account book to the local social security agency for handling.
