I am new to this magento world and stuck on a problem: I need to create a attribute rule which can add 20% in all prices by default. In fact I created a rule with name "standard VAT" in Sales->Tax->Manage Tax Rules.
However, by default Magento is using "None" as the default Tax Class in Product > Price > Tax Class. How can we make Magento use my tax class "Standard VAT" by default instead?
I know one way is by selecting all products and editing the Tax Class attribute, but that is not a viable solution for us. If we go this route we have to apply that edit too often as our listing updates every 30 minute.
We need a 1 time solution so that all our newly add products and existing products can automatically use the new Tax Class.
If you know any way we can edit any file in magento please advise us with full file path, code to add and line number.
Thank you for your help in advance.
