Ok, let me answer it for you. Amazon sellers need to declare and pay VAT according to the following steps:
Determine whether it is necessary to register the VAT tax number. If your goods are sent or entered from EU countries, or your annual sales exceed a certain amount, you need to register the VAT tax number.
Select the appropriate VAT service provider and entrust them to register and declare VAT for you. This will save you time and energy, and also avoid some common mistakes and fines. (such as Captain Bi)
Update your VAT information in the Amazon seller's backstage, including VAT tax number, address, telephone number, etc. In this way, Amazon can provide you with correct invoices and reports.
Submit the VAT declaration form on time every quarter and pay the corresponding VAT tax. Normally, the declaration and payment should be completed within one month after the end of each quarter. If there are any changes or special circumstances, the tax bureau and Amazon should be informed in time.
I hope this information is helpful to you.
