In many areas of the back office you will have to enter VAT rates, for example with products and payment and shipping methods. Before you can enter a VAT rate, you will first have to create it through GENERAL > Settings > Country settings > Tax in the left menu of the back office.
Click the green plus icon in the navigation at the top of the screen. A pop-up window will open, where you can enter a name for the VAT rate in the Title field, for example 21% VAT. Enter the applicable VAT rate in the Percentage field. If you want to specify a VAT rate of 21%, enter a value of 21.00 here.
Do you utilize a number of VAT rates? If so, you can choose one as the standard rate. Do this by clicking the star icon next to the desired rate. This rate is automatically passed on with the creation of new products.
If changes in applicable VAT rates should occur in the future, you can modify a VAT rate by clicking the pencil icon next to it to implement changes using the Title and Percentage fields.
