Product price includes vat but its also added at checkout

[gmourelatos@.....com]

Hello.
All my products include VAT in their price while on OPC2 checkout page they have tax added once more.
If I disable OPC2 and refresh checkout page then VAT is not shown at all therefore not calculated.

How can I have VAT shown but not added in OPC2?

Hello, OPC does not alter the tax, it uses the VM core files to count it. Let us know what is your VM version and what is your configuration at OPC Tax tab, also please provide an example of the wrong OPC calculation so we can test it.

Best Regards,

Hello, i believe that your TAX (calculation) configuration is misconfigured. Please make sure that you only have the tax calculated for -default- and -anonymous- shopper groups within one tax rule and that no other rule will also count the tax for this. If you have one tax rule without any shopper groups and the other set up for -anonymous- the tax might be added twice.
