* This step retrieves the tax lines for an order or cart's line items and shipping methods.

* :::note

* You can retrieve an order, cart, item, shipping method, and address details using [Query](https://docs.medusajs.com/learn/fundamentals/module-links/query),
* or [useQueryGraphStep](https://docs.medusajs.com/resources/references/medusa-workflows/steps/useQueryGraphStep).
*
* :::
*
* @example
* const data = getItemTaxLinesStep({
* orderOrCart: {
* id: "order_123",
* // other order details...
* },
* items: [
* {
* id: "orli_123",
