Is it invalid to pay social security for less than one year?

Legal analysis: not invalid. After workers participate in social insurance, social security agencies will establish personal accounts for basic old-age insurance and medical insurance for life. If you need to continue to pay after leaving your job for one year, you can choose to participate in insurance in the name of an individual, affiliated with other units or continue to participate in insurance in a new unit. Because the social security personal account will remain unchanged for life, it will not be reopened.

Legal basis: Article 57 of the Social Insurance Law of People's Republic of China (PRC), the employing unit shall, within 30 days from its establishment, apply to the local social insurance agency for social insurance registration with its business license, registration certificate or unit seal. The social insurance agency shall, within fifteen days from the date of receiving the application, examine and issue the social insurance registration certificate. Where the social insurance registration items of the employing unit are changed or the employing unit is terminated according to law, it shall, within 30 days from the date of change or termination, go to the social insurance agency to handle the change or cancellation of social insurance registration. The market supervision and management department, the civil affairs department and the organization management organ shall promptly inform the social insurance agency of the establishment and termination of the employing unit, and the public security organ shall promptly inform the social insurance agency of the birth, death, household registration, migration and cancellation of the individual.
