Specific analysis and solutions are as follows:

1. VAT has not been declared, and the card should be cleared after the declaration is completed;

2. If the declaration comparison fails, verify the reasons for the failure and contact the relevant operation and maintenance departments of the core collection and management for processing;

3. The process of summary upload-VAT declaration-remote card clearing was not followed, and the process was followed again after the declaration was invalid;

4. The user's equipment is also associated with the old tax number, so it is necessary to unbind the old and new tax numbers in Bureau 2.0, then cancel the equipment under the new tax number, and then reissue it (cancel the equipment under the new tax number first, then cancel the equipment under the old tax number, and then reissue the equipment under the new tax number). If there is no release information of the old tax number at 2.0, it needs to be reported to the operation and maintenance department, and the card will be cleared after operation and maintenance;

5. Users are ordinary taxpayers. 2.0 The bureau shows that the user's declaration type is quarterly and needs to be changed in the tax administration system. If this method is ineffective, it needs to be reported to the operation and maintenance department.
