In the core collection and management system, the value-added tax has not been declared or compared, that is to say, when clearing the card, it will generally prompt that the value-added tax has not been declared, or the data comparison has failed, or the tax is declared first and then the card is cleared.

If you don't declare, declare first and then clear the card. If you don't pass the comparison, go to the tax hall counter to clear the card. If the tax declaration is not copied, it should be invalidated first, then copied and declared, and then the card is cleared.

There are two possible reasons for this prompt:

1, electronic tax bureau failed to declare.

Before "writing prevention monitoring", you need to report to the electronic tax bureau first. After the declaration, operate "write prevention monitoring".

2. The electronic tax bureau declared, but the "declaration summary" came after the declaration.

The correct process: first report and summarize, then declare by the electronic tax bureau, and finally write back to monitor.

The operation sequence is reversed. If there is no tax, the declaration form can be invalidated and the card can be cleared after re-declaration. If there is tax, you can only bring tax UKey, official seal and other related materials to the tax window to clear the card.
