Social security base declaration time

The reporting time of social security base varies from place to place, generally after May. However, some areas start to adjust in April every year, some areas start to adjust in July, and some areas do not adjust every year 1 month. No matter which city it is, whenever it applies for adjustment, it needs to make a series of adjustments after the local social wage amount is announced in that year. The declaration of social insurance payment base is based on the change of my salary and social average salary.
