In addition to the company's resignation certificate, you have to take the social security personnel increase or decrease form to the social security bureau to affix the official seal to stop the insurance. If you start online business, you can stop it directly online. If you leave your job in the current month, you must go through the formalities of stopping insurance before the 25th of the current month. The deadline for social security increase or decrease is 25th of each month. After that, the related business will not be processed until next month 1. That is to say, before this, all units and individuals must complete the procedures for increasing or decreasing social security personnel in the current month, otherwise the default automatic deduction will be transferred to the next month. Today is the 26th. If your old company stops insurance before 25th, you can apply for social security transfer in your current company from next month. However, if the original company fails to stop the insurance in time, the system will automatically switch to next month by default. This means that your social security will continue to be paid 1 month in your original company. In addition: the original unit can only stop your insurance at the beginning of next month, so when you apply for social security transfer in your current unit next month, it will not take effect until next month.
