This setting was previously called: Set up VAT.
Purpose: Depending on your business, VAT may need to be enabled and set up. This page will allow you to do so, as well as tweak the settings a bit.
- Go to profile button > settings > use search functionality or navigate via the left handed 'Categories' area >Sales tax.
- Enable VAT, set the default label (by default it will be VAT), and select if VAT should be included in invoices automatically or not. Hit save.
