Social security is not paid for one month.

Legal analysis: it will be broken if you don't pay social security for 3 months. Insured personnel should be insured within 3 months after being included in the scope of insurance, and enjoy the next month after paying medical insurance premiums for employees. Failing to go through the insurance formalities within the specified time, or interrupting the payment for three months in a row, it is regarded as interrupting the insurance. After the interruption, you can go through the insurance procedures and pay for 6 months in a row before you can enjoy medical insurance benefits. If it is paid within three months, it will enjoy medical insurance benefits from the next month.

Legal basis: Article 57 of the Social Insurance Law of People's Republic of China (PRC) stipulates that the employing unit shall, within 30 days from the date of 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.
