Well, nearly two years on and no progress on this improvement? I am developing a store in CA with products that are subject to excise tax. Despite applying the correct taxonomy / categorization to my products, the excise taxes are not applied. I then applied an override using a custom collection but have no way to separate out the sales tax from the excise tax component on the checkout screen.
Here’s why this matters. In California the sales tax rate is +/- 9%. The excise tax is +/- 12%. So I am showing my customers a +/- 21% tax at checkout that is simply labeled “Estimated Taxes”. That is plainly insufficient and will deter a lot of customers who think we’re trying to somehow inflate their pricing under the guise of additional taxes. Breaking these out into line items is a simple ask that will remove this friction.
It is disappointing that important requests like this don’t properly bubble up from this forum to Shopify’s development priorities. It’s a lack of visibility on failures like this that pushes customers to other solutions.
