How long can a Shanghai company delay the payment of social security?

It's just that the unit doesn't pay social security, and directly takes the ID card and labor contract to the inspection department of the social security bureau that participates in the insurance to complain to the unit, asking for the social security that has not been paid since joining the company. Article 58 of the Social Insurance Law, the employing unit shall handle social insurance registration for employees within 30 days from the date of employment. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay.
