The company did not pay social security in full. Does the payment correspond to every month? Will the index go up?

It corresponds to every month and will improve.

Paying social security fees can improve the social security index. Social security index refers to the index related to social insurance contributions and social insurance premiums paid by individuals and units, which is used to measure the payment of social insurance premiums and the level of social insurance protection. When enterprises and individuals pay social security fees in full and on time, the social security index will remain stable or improve, reflecting the normal operation and security level of social insurance. When the company fails to pay the social security fees in full, the social security index will drop, reflecting the insufficient payment of social security fees. By paying back unpaid social security fees, the social security index can be improved, which shows that the payment of social insurance fees has been improved and the level of social security has also been improved accordingly.
