Tax control method and system for off-line invoicing based on taxpayers

Abstract

The invention discloses a tax control method and system for off-line invoicing based on taxpayers. The method comprises the following steps: setting a limit parameter extreme value for an offline invoicing terminal; counting the number of invoices issued by the off-line invoicing terminal in an off-line period, the number of off-line days and the accumulated invoicing amount; when any limit parameter of the offline invoicing device exceeds the limit parameter extreme value corresponding to the limit parameter within an offline period, converting the offline invoicing terminal into a service stop state; when the offline invoicing terminal is in a service stop state, connecting and communicating the offline invoicing terminal with a tax bureau end through a network to enable the offline invoicing terminal to be in an online state, terminating the service stop state, and starting to record a new offline period again. It is ensured that the latest tax calculation rule is synchronized in time during off-line invoicing, off-line large-amount illegal invoices are avoided, and meanwhile property losses caused by misoperation or illegal swiping and the like of taxpayers are protected to a certain extent.

Background technique [0002] With the rapid development of science and technology in recent years, high-speed network communication has covered most regions of the world, enabling people to enjoy the convenience brought by technology, and the country has also achieved better operations through technology. For example, in remote mountainous areas in China and many developing countries abroad, the network is not well developed, and the stability of the Internet is not good; in many areas, due to the underdeveloped network or even no network, in order to adapt to the special circumstances of these places, offline billing has to be promoted technology. However, since offline invoicing is performed on a single machine, it is difficult to control the invoicing behavior. For example: taxpayers ...

AI Technical Summary

Problems solved by technology

For example, in remote mountainous areas in China and many developing countries abroad, the network is not well developed, and the stability of the Internet is not good; in many areas, due to the underdeveloped network or even no network, in order to adapt to the special circumstances of these places, offline billing has to be promoted technology

However, since offline invoicing is performed on a single machine, it is difficult to control the invoicing behavior

For example: taxpayers maliciously issue a large number of invoices, resulting in a waste of invoice number resources, taxpayers still issue invoices at the original tax rate after tax rate adjustments, large-amount invoices for abnormal business transactions, etc.
