Include or exclude tax based on your customer's country
Shopify recently released a BETA feature that you can find in your Shopify Admin Settings > Taxes.
If you enable this feature, our Upsell Builder discounts may not work correctly during checkout. If you use this feature, kindly contact our support team to ensure that discounts are correctly applied from the Cart page to the Checkout pages. To know more about how discounts are applied from the cart page to the checkout page, follow this link.
Per Shopify:
If you sell internationally, then you can include or exclude taxes in your product prices based on your customer's location. If you enable this setting, then customers in countries or regions such as the United Kingdom see prices inclusive of their local value added tax (VAT), or exclusive of taxes in countries or regions such as the United States, where buyers expect to see taxes added at checkout.
