Why did social security suddenly drop this month?

Hello, dear, I'm glad to answer your question. Why did social security suddenly drop this month? This question gives you the following answer: there are two situations in which social security contributions suddenly drop. One is that your social security contribution base is reduced. After the payment base is reduced, social security is paid in proportion to the payment base, so the payment will also be reduced. The other is that the state only supports small and medium-sized enterprises after the company implements the preferential policy of reducing and exempting social security contributions, and the unit commitment ratio is reduced from 20% to 16%.
