If you are store owner that's selling in any country in Europe (example: German invoice has tax named Mswt), the invoice generated default by Shopify might not show Mswt split, which's mandatory to be shown alongside Total. This is possible with Tax override option on F : PDF Invoice - Order Printer App

In this tutorial, we will show you how to configure it correctly

Preferences -> General -> Tax Override

And enable checkboxes, the second checkbox is not needed unless you see any error in the way it is calculated.

Then save

After it's done, you will see 2 taxes, one by Shopify and one generated by tax override. So you would have to turn off other one. For that, go to Templates-> Customize-> Total-> uncheck  Tax and check Custom Tax. Then save.

If you face any issues, feel free to contact live support. Our support agents will jump on a Zoom call and troubleshoot if there's any questions.

Hope this helps
