I want to ask about the accidental payment of medical insurance in previous years. If the information has been sent to the tax bureau but has not been paid back, how can I cancel the payment? Is anybody there? Hello, after the successful declaration, you can operate online before the approval of the Social Security Bureau. Log on to the social security website, enter the user name and password of the enterprise, click on one of the declarations, select the one inside, and cancel the declaration. If it is approved by the social security bureau and cannot be cancelled, it can be paid across provinces and later. If you die for some reason, you can receive an online social security declaration, which is generally renewed once a year. If the fee is not renewed, it will be cancelled automatically.
