After the "three certificates in one", how does the unit pay the social security fee? Do you need to go to any functional department to modify the data?

In fact, after the integration of the three certificates, it is not necessary to go to the social security bureau for changes, because unless the bank account number is changed, it is necessary to go to the social security bureau for changes. The integration of three certificates only has a new unified social credit code, not a change of bank account number, so there is no need to change social security.

Your company's social security fee cannot be deducted, which has nothing to do with the integration of the three certificates. It is recommended to check whether the company account number has changed. In addition, whether the new bank account has been registered or changed in the Social Security Bureau. Once these problems are solved, the expenses can no longer be deducted. It may also be because the account is out of money, or the social security rate has changed, and the fee can no longer be deducted.
