Credit Card VAT Tax
You can learn a bit more about setting up VAT taxes by checking out this link.
To add VAT amounts to Credit Card Bills, you will first need to create a CC Purchase Type (Expenses -> Credit Card Purchases -> CC Purchase Types) and link it to a VAT/sales tax record. When adding the Purchase Type, select the tax in the box labeled If Type is Tax.
After creating a CC Purchase Type for the VAT tax, you can add VAT amounts for credit card charges by going to Expenses -> Credit Card Purchases -> New Credit Card Purchase and selecting the VAT Charge Type.
You can pull these purchases into a Credit Card Bill by going to Expenses -> Credit Card Bills -> New Credit Card Bill.
VAT amounts from Credit Card Bills will then appear on the Income -> Reports -> Billing -> Sales Tax Report.
