Social security contribution is different from wage deduction.

Legal analysis: social security payment is equal to the payment base multiplied by the payment ratio. You should go to the social security department and ask what your basic salary is. Is it in line with your actual situation? For example, in Shanghai, from April 20 13 to March 20 14, the payment base is from 20 12 to 12, and the average monthly income of employees (the income of new employees in 20 13 is determined according to the income of the first month) cannot be. Payment ratio: individual 1 1% (rural household registration 10%). If the calculated individual payment is different from the actual amount deducted by the unit, you should negotiate with the company again. If the negotiation fails, labor arbitration will be conducted again.

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 administrative department for industry and commerce, the civil affairs department and the organization management organ shall promptly notify the social insurance agency of the establishment and termination of the employing unit, and the public security organ shall promptly notify the social insurance agency of the birth, death, household registration, transfer and cancellation of an individual.
