The more social security contributions the better?

Social security contribution base is 60% of the average social wage - 300% of the payment base, for example, the average social wage is 1,000 yuan, the payment base can be 600 yuan - 3,000 yuan. For example, in Shanghai in 2004, the average monthly salary was 1,847 RMB. If your monthly salary exceeds 1847*3=5541 yuan. If your monthly salary exceeds 1847*3=5541 yuan, then the social security payment base is 5541 yuan; if your monthly salary is less than 1847*60%=1108.2 yuan, then the social security payment base is 1108.2 yuan. If your salary is between 1108.2 and 5541 yuan, the base is your salary.

Article 58 of the Social Insurance Law An employer shall, within thirty days from the date of employment, apply to the social insurance agency for social insurance registration for its employees. If the employer fails to register for social insurance, the social insurance administration organization shall approve the social insurance premiums to be paid by the employer. Individual entrepreneurs without employees who voluntarily participate in social insurance, part-time workers who do not participate in social insurance with their employers, and other flexibly employed persons shall apply for social insurance registration with the social insurance administration organization. The State establishes a nationally unified individual social security number. Individual social security numbers are citizens' identity numbers.
