Is there a reason why the Tax Rule Line is designed so that the Substitution Tax must be in the same Tax Group as the Original Tax?
In the UK there is a cash accounting scheme that can be used with VAT returns. I think the Tax Cash Module is intended for use with these types of schemes. However, when using this scheme even though most transactions are based on payments instead of invoices, there are some that are still based on invoices (such as Imports and EU acquisitions). I think that if I put these taxes in separate tax groups, I can configure the system to report these correctly?
If so, I’m planning on creating a tax rule for Non-EU Suppliers. This would take the standard tax and change it to an Import of Goods tax. This is where the problem arises, as these two taxes need to be in different groups to support the cash accounting scheme.
