The input is 0. Do I still need to confirm my signature?
No need. Entering 0 means that the taxpayer has no VAT invoice to be seized in this period, but the information of Hainan Provincial Taxation Bureau in State Taxation Administration of The People's Republic of China, People's Republic of China (PRC) shows that if the taxpayer has no VAT invoice to be seized in this period, it is not necessary to conduct "application statistics" and "confirmation signature" in the platform.
