The risk of invoice nullification is huge, and many enterprises start to nullify a lot of invoices as soon as the end of the month when they find that the input items are not enough, thinking that the tax is tax-control by invoice anyway, and nullifying invoices to reduce the output items seems to be the most obvious way to save tax.

Unbeknownst to me, the Cash Tax IV + VAT Risk Prevention and Control Early Warning System + Big Data, as long as you dare to illegally scrap, the tax bureau will dare to check you! The risk of illegal voiding tickets is huge, and serious cases may be referred to the judicial authorities.
