The first month's salary is deducted for 2 months' insurance.

Legal analysis: 1, because the social security account is established for the first month, two months of social security will be deducted directly. This should be coordinated by the unit, and the salary of the current month should be deducted according to the month when employees pay social security.

2. If social security is deducted for two months in the first month, the social security fee paid in the month of resignation cannot be deducted from the salary of the last month.

Legal basis: Article 72 of People's Republic of China (PRC) Labor Law determines the source of social insurance funds according to the types of insurance, and gradually implements social overall planning. Employers and workers must participate in social insurance and pay social insurance premiums according to law.
