First, the social insurance law clearly stipulates the payment targets of basic old-age insurance, basic medical insurance, industrial injury insurance, unemployment insurance and maternity insurance:
1, employees shall participate in the basic old-age insurance, and the basic old-age insurance premium shall be paid by both employers and employees. Generally speaking, the endowment insurance is 20% for the unit and 8% for the individual;
2 employees shall participate in the basic medical insurance for employees, and the employer and employees shall pay the basic medical insurance premium in accordance with the provisions of the state. Medical insurance: 8% for units and 2% for individuals;
3. Employees should participate in work-related injury insurance. Employers pay work-related injury insurance premiums, but employees don't. Work-related injury insurance is borne by enterprises, which is around 1%, and individuals don't need to pay it. For enterprises in different regions and industries, the proportion paid by units is slightly different, subject to local regulations.
4. Employees should participate in unemployment insurance, and employers and employees should pay unemployment insurance premiums in accordance with state regulations. Unemployment insurance: unit 2%, individual 1%.
5. Employees shall participate in maternity insurance, and the employer shall pay maternity insurance premiums in accordance with state regulations, while employees shall not pay maternity insurance premiums. Maternity insurance is borne by enterprises, which is about 1%, and individuals do not need to pay it. For enterprises in different regions and industries, the proportion paid by units is slightly different, subject to local regulations.
Second, social insurance is a kind of insurance required by the state. The state develops social insurance undertakings, establishes a social insurance system and sets up a social insurance fund, with the aim of enabling workers to get help and enjoy insurance benefits in old age, illness, work injury, unemployment and childbirth. China's "Labor Law" and "Social Insurance Law" clearly stipulate that it is the legal obligation of the employer to pay social insurance for workers, which is obviously compulsory by the state, and the employer shall not refuse to undertake this legal obligation under any excuse or reason.
