Tax is calculated using the fulfillment location that Order Routing selected. Local pickup is based on the pickup location. The ship-from location that was used is recorded on the order.
If you fulfill from multiple locations, tax now reflects where the order actually ships from.
For local pickup orders, tax is calculated based on the pickup location.
The ship-from location used in the calculation appears on the order record, backing up your reports and filings.

It is not stated which plans or which tax feature configurations this is enabled for.
No rollout schedule is described beyond the publication date (August 24, 2026).

The announcement covers only orders shipped to customers in the United States.
Now that tax calculation takes its input from the location chosen by order routing,reviewing your routing settings is the work that improves tax accuracy. Looking only at your tax setup won't fix it.
The clear beneficiaries are stores that fulfill from multiple locations. With a single location the ship-from point is already unique, so the change is limited.
Shipping is based on the ship-from location; pickup is based on the pickup location.the same cart can be taxed differently depending on the delivery method chosen— factor that into your storefront display and quoting logic.
Because the order record retains the location the calculation was based on,tax discrepancies can be explained by which location the order shipped from. That makes it easier to answer questions from accounting.
The post says nothing about new Admin API fields, retroactive application to existing orders, eligible plans, or whether any activation step is required. If you sync tax amounts and ship-from locations with an external accounting or ERP system,place a real order in a development store and check the differences before rolling this out to production. See the order routing documentation in the Shopify Help Center for details.
