## Tax and Duties are deprecated in Storefront Cart API

As of API version `2025-01`, we're deprecating the [tax and duty](https://shopify.dev/docs/api/storefront/2024-01/objects/Cart#field-cost) fields in Storefront API Cart. Tax and Duties are calculated at Checkout where they can be finalized with the complete context of the buyer's information, ensuring greater accuracy.
