i have added gst in my product. while calculating the gst amount it's based on product price+shipping amount,
but i need to calculate gst amount product price*gst amount. kidnly refer this example
Example:
product price (200) * gst(5%)+shipping amount(50)

If you don't want to charge GST on shipping, then you need to remove the tax class from your shipping method. You do that in Extensions > Shipping, then click Edit for whatever shipping method(s) you are using. You should be able to set the tax class to "None" from in there.
