The new company did not apply for social security registration.

Hello, "employers and workers must participate in social insurance and pay social insurance premiums according to law."

If the employer fails to apply for social security registration or fails to pay the insurance premium, the social security agency has the right to punish:

According to Article 84 of the Social Insurance Law, social security agencies have the right to order employers who have not registered for social security to make corrections within a time limit. If no correction is made within the time limit, a fine of more than one time and less than three times the social insurance premium payable shall be imposed; The directly responsible person in charge and other directly responsible personnel shall be fined from 500 yuan to 3000 yuan. At the same time, Article 86 stipulates that if the employer fails to pay the social insurance premium in full, it shall be ordered to pay it within a time limit or make up for it, and a late fee of 0.5% shall be added daily from the date of default; Failing to pay within the time limit, a fine of more than one time and less than three times the amount owed shall be imposed.
