Currently, tax at checkout is calculated using static, account-level defaults and does not adjust based on the customer’s shipping address or applicable tax laws for the vendor. Additionally, static shipping costs can display in the shopping cart, but they're are not calculated during checkout based on shipping address information entered into the shopping cart. This feature would enable real-time calculation of both tax and shipping based on the shipping address entered by the customer. Taxes would automatically reflect applicable tax laws, nexus requirements, and location-based rules, while shipping costs would dynamically surface and update in the shopping cart prior to purchase. Implementing this would improve pricing accuracy, ensure tax compliance, and provide customers with greater transparency during the checkout experience.
