Hi Shopify Community,

I’m building a wholesale site using Shopify B2B and have run into a challenge. My store needs to collect state tax based on the original list price of products, even when offering discounts to business customers. However, I’ve noticed that Shopify’s discount codes apply to the entire order, including the tax, which results in the tax being calculated on the discounted price instead of the list price.

I’ve considered using store credit as a workaround, but unfortunately, Shopify B2B doesn’t support store credit functionality.

Does anyone have suggestions or alternative solutions for this issue? I’d love to hear how others have handled similar situations. Thanks in advance for your help!
