We have a Magento store (M1) and it is configured to add Indian GST. Currently, it's adding the tax separately on checkout page resulting in increase final price. We would like to configure it in the way that CGST & SGST are bifurcated & displayed, but are not added separately.
Ex. If the price of the product is Rs.1000 & GST amount is 18%, it should show like this on checkout:
which means the shop shouldn't add the GST separately but it should be inclusive in the final price. Same should appear on email invoices as well.
PS: CGST & SGST calculation feature is already configured. Also, we have customized our checkout page.
