VAT Calculations

[Gingerweb]

On Invoicing a customer purchasing discounted items in checkout is taking the original figure to calculate the VAT so on an original price £15.00 (£12.50 + £2.50 VAT) if you discount to £10.00 (£8.33 + £1.67 VAT) on the invoice the amount will show as £7.50 + £2.50 VAT, so the total is correct but the VAT element is not. This error is on the individual item so the VAT for non-discounted items and shipping on the invoice is correct but the total obviously is not.
Any ideas how to correct this please?

Is your Tax & Calculation Rule for discount set to Price modifier after tax  or to Price modifier before tax?

I have just got one tax rule set at tax per product (as screenshot) im guessing then, not having seen this before, that i would need more than one rule, how is it normally setup ?
thanks

That is the normal setup. When you have a national store and you sell products with the same vat rate, you need only one calculation rule, completly correct.

How do you set the discount rate for products? A preferred way is to set up a discount tax and calculation rule, assign that to a "discount" category which is unpublished, and then assign any discounted products to that category as well as their own.  https://docs.virtuemart.net/manual/general-concepts/204-tax-and-calculation-rules-overview.html

Thanks both.
The discounts are currently setup using AWOCoupon.
I will have a look at the Tax rules overview and see what we can do.
cheers
