Shopify puts tax on return shipping fees on automatic from October 23
A Shopify changelog entry dated September 25, 2026 says that from October 23, 2026 the tax owed on return shipping fees will be calculated and applied automatically. The change covers merchants in the United States using Shopify Tax or Tax Platform, for orders shipped to US addresses. Merchants running a manual workaround today are asked to review it before that date so the tax is not counted twice.
The calculation moves from the merchant to the platform
Shopify published the entry on its changelog on September 25, 2026 under the headline "Tax is now calculated on return shipping fees". From October 23, 2026 onward, Shopify Tax and Tax Platform will work out the tax due on a return shipping fee and apply it without the merchant stepping in. In Shopify's own words, "Shopify calculates and applies the tax automatically". Two conditions bound the scope: the merchant has to be in the United States, and the order has to ship to a US address.
The change does not reset an existing tax setup. Shopify says current shipping tax settings still hold, and that in states where shipping is not taxed the return shipping stays untaxed as well. The entry does not change the rate applied: in Shopify's wording, return shipping fees will be taxed like any other shipping charge. Shopify's stated reason is that merchants then do not need to fix under-collection on returns. A step that has been sitting on the merchant's side moves inside the platform's own flow on October 23.
An estimate when the return opens, the final figure at processing
The entry also sets out how the flow behaves. When a return is created, the merchant sees an estimated tax amount; the final amount is recorded as the return is processed. Shopify says that figure then flows into tax reports automatically, so no separate step is needed to carry it across. The estimate and the definitive amount landing at two different moments is a distinction the announcement draws explicitly.
What merchants are expected to do splits in two. Anyone who calculates, collects, imports or reconciles the tax on return shipping by hand today, that is running a manual workaround, needs to review that process before October 23, and Shopify's stated reason is to keep the tax from being counted twice. For everyone else, no action is required. The September 25 publication leaves merchants a preparation window ahead of the effective date.
The exposure sits in the old workaround, not the new feature
The double-counting warning is the operational heart of this entry. Once the automatic calculation is live, a setup that keeps adding the tax manually will show the same amount twice, and Shopify's call to review before October 23 is aimed precisely at that outcome. The warning is addressed to merchants who built a correction step of their own; for everyone else, Shopify says no action is required.
The second point is reporting. Because the tax on return shipping will now reach tax reports through the platform, the source of the number a merchant reads in those reports changes. The narrow scope matters too: the entry speaks only about US merchants and orders shipped to US addresses, and says nothing about any other country or tax regime. We covered a Shopify move on the checkout side on September 22; this entry is about the accounting after the sale rather than the storefront.
The source says nothing about Türkiye, so this section is commentary
Shopify's changelog entry contains not a single statement about Türkiye. It says nothing about whether merchants there are affected, nothing about the status of Shopify Tax in the country, and nothing about how return shipping is treated for tax purposes locally. The text is built end to end on merchants in the United States and orders shipped to US addresses. What follows is therefore not a fact drawn from the source but explicitly UNALSOFT commentary.
Our reading is this. In many businesses the tax on return shipping is one of those line items added to the ledger by hand afterwards, and every hand-added line item creates a double-entry risk on the day it becomes automatic. For a business in Türkiye running infrastructure other than Shopify, the practical question that follows is simple: in your returns process, who calculates the tax and at which moment, and is the same amount added again somewhere else. The unknowns deserve the same clarity. The source does not say whether there is any equivalent for merchants in Türkiye, whether similar automation is planned for other countries, what happens to stores shipping from Türkiye to US addresses, how far the estimate and the final amount can diverge, how returns created before October 23 are handled, whether the feature can be turned off, or whether Tax Platform providers are affected differently. There is no independent second source either, since both listed sources are Shopify's own publications.
The UNALSOFT view
This looks like a one-line product note, but it points at a pattern businesses know well: when a platform takes over a calculation people used to do by hand, the real exposure is not the new feature, it is the old workaround left in place. In our work that translates into being able to see, from one place, where the tax line in a returns flow is actually calculated. Our e-commerce panel projects keep order, return and amount data in the same panel, because you only notice that one line item is being calculated in two places when you can look at both side by side. Since the source says nothing about Türkiye, this article makes no prediction about whether the change reaches merchants here.
