Shopify merchants who charge customers for return shipping have a specific bookkeeping check to make this week. Starting October 23, 2026, Shopify says it will calculate tax on return-shipping fees for eligible orders shipped to U.S. addresses when the merchant uses Shopify Tax or Tax Platform.
The practical risk is not that every return suddenly becomes taxable. It is that a store already handling this tax manually could collect it twice when the platform starts calculating it.
The change is described in Shopify's return and cancellation rules documentation. This is a platform calculation change, not an announcement of a new nationwide tax.
Who needs to check
According to Shopify, the calculation applies only where the return-shipping fee is taxable in the jurisdiction the original order was shipped to. The tax appears alongside the return-shipping fee when a return is created and is included in the return's total tax.
The documentation lists important limits:
- Orders shipped outside the United States are not included in this calculation.
- Merchants using other tax services, including Manual Tax or Basic Tax, are not included.
- Tax-exempt orders are excluded.
- Shopify does not calculate tax on restocking fees under this feature.
That last distinction matters. A charge for sending a package back and a charge for restocking merchandise are separate fields and should not be treated as interchangeable by staff or a bookkeeping spreadsheet. Shopify's broader shipping-tax guidance also makes clear that whether shipping is taxable varies by jurisdiction.
Find the workaround before Friday
Shopify explicitly tells merchants using a manual process to calculate, collect, or reconcile this tax to review it before October 23 so tax is not collected twice.
For a small store, that review can be concrete:
- Confirm your tax service. Ask whoever manages store taxes whether you use Shopify Tax, Tax Platform, or another service. Do not assume the change applies just because you sell on Shopify.
- Trace one recent paid return. Locate the return-shipping fee, any associated tax, the customer refund, and the bookkeeping entry. Identify whether a staff member, app, or spreadsheet adds tax outside Shopify.
- Assign the handoff. If a manual step overlaps the new calculation, have your bookkeeper or tax adviser decide how it should change. Keep the existing records rather than deleting the audit trail.
- Check the first applicable return after the change. Compare the fee, tax, refund, and accounting entry. Confirm the same amount is not being charged through two different steps.
Do not switch off tax collection broadly to solve a possible duplicate. The question is which process handles this particular charge, not whether the store should collect sales tax at all.
A calculated fee is not a completed refund
There is another operational detail worth putting in the staff checklist. Shopify's return-rules documentation says return fees are not automatically deducted from refunds; the merchant needs to deduct applicable fees manually when creating the refund.
That makes the final refund review important even when tax calculation is automated. Give the person processing returns a clear way to distinguish the merchandise refund, return-shipping fee, applicable tax, and any separately disclosed restocking fee.
The owner takeaway: Before October 23, find out whether this change applies to your store and who currently handles return-shipping tax. Then check an actual eligible return after the change. One short reconciliation is more useful than assuming an automated calculation has replaced the entire returns workflow.
