Using NewOrder I see no automated TAX calculation happening (I am also not able to modify it myself)
As suggested some time agoby the SupportTeam we had to set our default country TAX straight into the database as show in the picture.
We have 19% high ( 6% low) TAX in the Netherlands.

All items are set to use the default TAX.
For printing PostageLabels we were advised by SupportTeam to rename the Country into Nederland straight into the database as well.
That's why you see Nederland as country in the NewOrderScreen

- no tax calculation

dbo.ListCountries - we only renamed the Fullname for the NL record into Nederland
I just noticed this is now available in Settings - Application Settings - Manage Country List
I also tried to set 19.6 or 0.196 as TAX value here but nothing is calculated.
Also creating a new order to country United States shows no calculation.
Please advise since this was something we were waiting for.
