How do I display or add taxes on my cross sells?

If you do not include taxes in your product prices, then taxes will not show up by default with cross sell (see this article for reference https://community.shopify.com/c/Shopify-Design/Product-pages-Show-VAT-prices-on-your-product-pages/m-p/614976 )

To get this done, you need to add a tax multiplier in our app's Settings -> Theme Then scroll down to Advanced section.

Example: If you use a 10% sales tax, then just add 10 to our app's tax multiplier and click save.
