Shopify return-shipping tax changes on 23 October: check manual workarounds

Shopify will start calculating tax on eligible return-shipping fees on 23 October 2026. The change covers orders shipped to US addresses when a merchant uses Shopify Tax or Tax Platform. If your team currently adds this tax through a manual process, review that process before the change to avoid collecting it twice.

Shopify announced the update on 25 September. It says the return screen will show estimated tax when a return is created, record the final amount when it is processed, and carry the amount into tax reports.

Which returns are covered?

The return-rules documentation sets out the boundaries. The fee must be taxable in the destination jurisdiction. Existing shipping-tax settings continue to apply.

Scope of Shopify’s announced return-shipping tax calculation

Situation	What the documentation says
US-address order, Shopify Tax or Tax Platform, taxable fee	Automatic calculation starts 23 October
Order shipped outside the US	Outside this calculation update
Manual Tax or Basic Tax	Not covered by this feature
Tax-exempt order	Return-shipping tax is not calculated
Restocking fee	This feature does not calculate tax on it

Those are software-feature boundaries, not a determination that an excluded fee is legally tax-free. The update describes what Shopify calculates; it does not replace a merchant’s assessment of its tax obligations.

Find the workaround before it becomes a duplicate

Our suggested preparation is a short review with the person who owns returns and the person who reconciles them:

• Identify any spreadsheet, app rule or manual adjustment that adds tax to a return-shipping charge.
• Record where that amount reaches the customer refund and the accounting export.
• Agree which step should change once Shopify supplies the amount, then check the first applicable return after 23 October.
• Compare the return record and report with the expected treatment before repeating the process at scale.

For example, if an operator adds a manual tax adjustment and an integration also imports Shopify’s calculated amount, the same charge could be counted twice. That is the kind of workflow to investigate; it is not a reason to turn off shipping tax across the store.

Shopify says merchants without a manual workaround do not need to take action for this update. Keep this review separate from deciding how long customers have to return an item: our return-window overrides guide covers that policy setting.
