Adding your VAT number will allow you to pay the fees without tax. There are three ways you can add your VAT number. 

Where can I add/modify my VAT number

1. From your "Payment History" page

You can easily add or modify your VAT number by going to your Payment History. You will find your Payment History if you hover with your mouse on top of your profile picture and your name in the top right corner of your account:

In the drop-down menu, select the option "Payment history":

On your Payment History page, click on the line "Save VAT Number":

On the next page, you will be able to add or modify your VAT number. Do not forget to validate it once you have added it.

2. From your profile

You can also add your VAT number by clicking on "Profile" in the upper menu of your account:

Scroll down until you can see your personal information and click on the blue option "Add" next to the line "VAT number" or if you wish to modify the existing number, click on "Edit" in the top right corner of the personal information section (next to your picture and your name):

The page will then reload and allow you to fill in/edit the information in every field. Simply enter/modify your VAT number and click on "Save" in the top right corner of the personal information section:

Once saved, your VAT number will be displayed in your profile and you will also be able to see it on your "Payment History" page.
