ShipWorks version 5.18 or later allows you to enable VAT taxes so that they are not displayed as a separate Sales Tax charge for Amazon UK orders. This is beneficial when the VAT tax is included in the line item total and the additional Sales Tax line item is causing the order total to be incorrect.
First Things First
In order to enable VAT tax for Amazon UK stores in ShipWorks you must be running ShipWorks version 5.18 or later. To check which version of ShipWorks you are currently on, click on the Help tab and then on the About ShipWorks button. For assistance with upgrading to the latest version of ShipWorks, click here.
You must be logged into ShipWorks as a user with administrator rights.
1. Click on the Manage tab and then on the Stores button.
2. Select your Amazon UK store and click on the Edit button.
3. Select Store Setting on the left side of the Store Settings screen.
4. Locate the Amazon VATS: section and select Enable from the drop-down menu.
5. Click OK and then Close.
Since VAT tax is enabled, the Value Added Tax is included in the line item total and no separate Sales Tax charge is displayed.
