What is the difference between "tax declaration" and "real-time tax payment" under the banner of ICBC corporate online banking bank tax?

"Tax declaration" is a process of active tax payment, and tax information needs to be entered manually. "Real-time tax payment" means that you get an electronic serial number for external declaration from the tax bureau, through which you can find out what taxes you need to pay, and just pay taxes directly. If you have obtained the electronic serial number of foreign declaration, you don't need to declare tax again, just pay tax directly.
