To begin the process of activating VAT tracking, navigate to the Taxation - VAT Tracking page.
In the Product list, choose Expense. Under the Capture Spending section, select the VAT tab, and then choose Fix.
This takes you to the VAT Tracking page where you can manage VAT settings.

Note
Once the Value-Added Tax (VAT) is enabled for all countries and regions, the Fix button will be replaced by the Edit button to access the VAT Tracking page.
