Hello, I'm glad to answer your question. 1. If this happens to the newly downloaded tax withholding system, the downloaded version may be wrong. Go to the electronic tax bureau to download the latest version. 2. If there is no problem using the withholding system before, then open the client to display the download update, and suddenly it cannot be uploaded after the update. In this state, you can try to change the identification number of 18 to 15 (remove the first two digits and the last one). If not, go to the front desk of the tax office, because the tax registration information needs to be maintained. 3. Enterprise information does not exist or does not need to be distributed. Generally, it is the media declaration selected during initialization, but the tax identification number or name is wrong, and enterprise information cannot be obtained after networking. If the client has multiple enterprise information, switch to another enterprise first, and then delete the problematic enterprise. If all the above methods fail, it is recommended to contact customer service for consultation.
