What's the latest date of monthly social security downsizing?

Legal analysis: most of the social security increase will take effect next month, that is, the deduction will take effect next month, and the reduction will also take effect next month, so the deduction will continue in the same month. Some people take the fifth day of each month as the demarcation point. For example, employees added before the 5th of the current month can be counted as valid in the current month and need to be deducted in the current month. The reduction of personnel before the 5th day of the current month can be counted as effective last month, and the insurance has been stopped last month, so there is no need to pay for the current month.

Legal basis: Article 50 of the Labor Contract Law of People's Republic of China (PRC) stipulates that the employer shall issue a certificate of dissolution or termination of the labor contract when it is dissolved or terminated, and go through the formalities of transferring the relationship between files and social insurance for the employee within 15 days.
