If the company leaves and pays social security for one month, it will lead to duplication.

Repeated payment of social security needs to be refunded, but the social security payment has been transferred to the tax bureau, and you can apply to the local tax bureau for refund.

Repeated insurance can not enjoy double treatment, and it is suggested to stop paying social insurance that does not have labor relations. There is no way to refund the paid part for the time being. Only when the two social security systems are transferred together and the social security systems are merged in the future;

You will find that there are overlapping parts, and the Social Security Bureau will ask for a refund of some of them, and only the individual contributions can be refunded. For social security, all expenses are borne by individuals and there is a loss. The combined social security does not affect the accumulated payment period.

There are several ways to deal with double insurance:

1. If you repeatedly participate in employee medical insurance, in principle, you will keep the insured relationship at the place of employment;

2, repeated participation in residents' medical insurance, in principle, maintain the insured relationship of permanent residence;

3 students repeat insurance, in principle, keep the insurance relationship where their school is located;

4, cross-system repeated insurance and continuous participation in employee medical insurance 1 year or more (including 1 year), in principle, keep the employee medical insurance relationship;

5, for part-time, temporary jobs and other forms of flexible employees cross-system repeated insurance, retain the relationship that can enjoy the treatment, and suspend the repeated insurance relationship.

To sum up, because of national regulations, employees need to apply for resignation one month in advance, so the social security company will definitely not pay in the month of resignation. If the application is not made one month in advance, if the company thinks that the employee has breached the contract, the company has reason to stop the employee's social security, which needs to be communicated with the company.
