This proposal covers to check the ecommerce platform display the unit price includes Tax or not. If the unit price includes the Tax, we need to change the price and display the price without Tax at a single item level and add the price with Tax at the cart page.
Requirement
Check the ecommerce platform display the unit price includes Tax or not.
If the unit price includes the Tax, we need to change the price and display the price without Tax at a single item level and add the price with Tax at the cart page.
Our solution
In the SCA web stores by default the displayed price is the unit price without including the Tax. The price value is obtained from sales/price tab in the item record.

The price including the tax is displayed only in the cart section during estimating the grand total.
The strike through price displayed near the price value is the old price value

This is in the case of checking the price values after login to the webstore
In the case of customers checking the product price without login to the webstore the price displayed is in NZ currency as its the currency of the default subsidiary “Global parent”
So, now the price is displayed as per the requirement. The tax is calculated only in the cart page during the estimate of grand total. The price without tax is displaying in the single item level
