Finance exports Tuesday's UK invoices from the EU warehouse and two carts over £135 have no VAT line. The £90 order from the same morning still shows 20%. Nobody changed Settings, Taxes, or Locations on 29 September 2026. The next job is a sheet: every EU-to-UK shipping path, a test order on each side of £135, a yes or no for whether Shopify Tax still posted VAT when you are importer of record, and a written fallback before the next export week.
Introduction
This article teaches you to walk that checklist after the 29 September 2026 Shopify Tax change. Recording duties, currency, shipping, and catalog gaps in each market before Black Friday ads go live belongs in Shopify Markets Black Friday Traps: Duties, Currency, and Catalog Gaps. This piece stays on the tax engine: fulfilment location, the £135 split, and the method you will use if the line is missing.
Merchant threads this month keep returning to the same cluster. An EU brand that ships DDP into Great Britain as importer of record watched VAT vanish on orders over £135 between two afternoon checkouts. A UK store still showed a 20% home-rate estimate on a US country select until a full address landed. Shopify also posted a dated change for tax on US return shipping fees from 23 October 2026. The shared signal is a missing verification owner after a tax product move, not a missing registration number.
Treat the walk as a settings checklist and confirm filing, EORI, and importer-of-record duties with your accountant before you change a live rate. The table holds the whole job, and the sections after it show how you fill each column.
| Checklist row | What you record | Pass criterion | Owner |
|---|---|---|---|
| EU-to-UK shipping path | Origin location, order-routing rule, carrier, DDP or DAP | Every live path that can fulfil a UK order is named | Ops / 3PL |
| Importer of record | Who pays import VAT, and which UK VAT number sits on the invoice | IOR and registration match how the parcel actually moves | Finance / accountant |
| Test order at or under £135 | Checkout tax line, order tax line, VAT invoice | UK VAT posts at the expected rate on that path | Commerce |
| Test order over £135 | Checkout tax line, order tax line, VAT invoice | VAT posts when you are IOR, or the skip is written and accepted | Commerce / finance |
| Fallback tax method | Manual UK VAT, real UK pick location, or duties product | One engine owns the line, with a review date | Tech / finance |
| Next announced change | US return shipping fee tax from 23 October 2026 | Workaround reviewed so tax is not counted twice | Finance / returns |
List each EU-to-UK shipping path Shopify will fulfil
Start with the warehouse that picks the unit, not the country printed in Settings, General. Shopify Tax now reads the fulfilment location assigned to the order. Order routing, a 3PL app, or a staff override can send a UK cart to Stockholm, Poznań, or Tilburg even when a UK row exists in Locations.
Write one row per path that can ship to Great Britain this month. Include the origin location ID, whether that location is active, whether it holds stock for the SKUs you advertise in the UK, and the routing rule that would choose it. Add the carrier and whether the label is DDP (you are importer of record) or DAP (the buyer meets customs). Northern Ireland follows different VAT rules from England, Scotland, and Wales, so keep those destinations on separate rows if you sell there.
A location you added in 2024 because an older help article said "add an active UK location" still counts only if routing assigns the order there. Shopify's current tax-registration article says the store address is not a physical location for tax calculations, and an unused UK row leaves the £135 import threshold in place. If the location has never held stock and never shipped, treat it as a label in admin, not as a tax origin.
Print-on-demand and multi-warehouse apps add a second origin you will miss if you only export Locations. Place a cheap test SKU on each app location and see which location the order lands on. The path list is finished when every UK sale from the last 30 days maps to a row.
Confirm importer of record and the registration on that path
The £135 split in UK law is older than this Shopify Tax change. Consignments of £135 or less shipped into Great Britain from outside the UK are a point-of-sale VAT supply, so the seller charges VAT at checkout and remits it. Consignments over £135 are imports. VAT and duties then sit with the importer of record unless you already collected them and will pay them on the parcel.
If you ship DDP from an EU warehouse and you are the importer of record, you still expect a 20% UK VAT line on carts over £135, because you will pay that VAT as the importer and you have already taken it from the buyer. If the buyer is the importer, a missing VAT line on those carts can be correct, and the surprise arrives as a duty request on the doorstep. Write which of those two models you run on each path before you call the checkout "broken".
Record the UK VAT number that should appear on the invoice, the GB EORI if you import, and whether Managed Markets or a broker sits in the middle. Managed Markets, where it is available, makes Global-e the merchant of record for qualifying international orders. A UK or EU brand on ordinary Markets still owns the registration. Plan selection for Plus, checkout extensions, and B2B is a separate decision from this tax sheet, and it lives in Choosing the Right Shopify Plan.
Shopify Tax updates registrations you already connected and stays quiet when a new one is missing, so a path without a named number is a stop, not a test-order week. If finance cannot name the registration on a path, fix that row first.
Place test orders above and below £135
Use a development store or a staff-discounted live cart, and keep the same SKU, origin, and UK shipping address on both sides of the threshold. One order at £90 and one at £180 is enough to see whether the engine still splits. Repeat the pair on every path you listed, including the 3PL origin and any UK location you claim will pick UK demand.
Capture four artefacts per order: the checkout tax line before payment, the order tax line in admin, the VAT invoice Shopify Tax generated if you use that feature, and the fulfilment location stamped on the order. If checkout shows VAT and the order later does not, you have a capture or edit problem, not a threshold problem. If both are empty on the £180 cart and the fulfilment location is the EU warehouse, the 29 September logic is doing what the current help article describes.
Watch the country selector as well as the paid total. UK stores that use tax-inclusive pricing with a 20% home rate have seen that estimate appear on a United States country choice until a full US address is entered, even when the US market is set to skip collection. A buyer who bounces on a padded total never reaches the address fields that would clear it. If that estimate is scaring completing buyers, treat it as a checkout-display row on the same sheet, and use How to Fix Shopify Checkout Abandonment When Your Funnel Looks Healthy when the drop is already in the funnel.
Do the tests in the same week you will ship. A settings change on Monday is worthless if routing flipped the origin on Wednesday.
Record whether Shopify Tax posted VAT
Write a yes or no for each path and each side of £135. Add the fulfilment location ID you observed, not the location you expected. The useful sentence is "£180 from Poznań to Manchester, IOR is us, VAT missing, location 38421", not "taxes look fine in Settings".
Community reports after 29 September 2026 describe support first blaming a missing address on the ghost UK location, then confirming a deliberate logic change: VAT over £135 now follows where the order is fulfilled. The expected impact was described as small, which is why many finance teams found the gap on invoices two days later. If your sheet shows the same skip on every EU origin, you are looking at the product change. If only one 3PL path skips, you are looking at routing.
Hold the sheet against how you file. If you are importer of record and you already remitted 20% on those invoices, a missing checkout line means you are funding import VAT from margin until the fallback is live. If you were never IOR, a missing line may match the law and you still need doorstep-duty copy, HS codes, and a carrier that can collect. That second case is the Markets walk in the sibling post, because duties display and shipping profiles live there.
Keep Shopify Payments reserves and payout timing off this sheet, because a held payout after a chargeback review is a different finance job, covered in Shopify Payments Reserves: Does Upgrading to Plus Change Anything?.
Write the fallback tax method and the owner
Pick one engine per UK market and write the owner who can turn the others off.
| Fallback | When it fits | What it will not do |
|---|---|---|
| Assign UK orders to a real UK pick location | You hold UK stock and routing can send Great Britain orders there | A location with no stock or no routing rule will not restore VAT |
| Manual UK VAT rates | You need the 20% line back this week while you are IOR from the EU | It will not file VAT for you, and it fights Shopify Tax if both stay on |
| Collect duties and import taxes at checkout | You want duties and import tax on the same checkout, and you accept the fee | Shopify's considerations article says skip it when you only need UK VAT |
A real UK pick location is the setup the current help article describes for charging VAT on orders over £135 to Great Britain. Stock has to live there, and routing has to choose it. Opening a warehouse to satisfy a tax engine is an operations decision, not a checkbox.
Manual rates are the fallback merchants used in the first week after 29 September when they needed invoices to match DDP, and support has already called that path short-term, so write a review date on the same day you turn it on. If you leave Shopify Tax and manual rates both trying to own the UK market, you will spend the next month reconciling double lines and silent skips.
Collect duties and import taxes at checkout is the product support sometimes names when the Tax engine skips the line. It collects duties as well as import tax, and it can add a transaction fee. Use it when you actually want that checkout behaviour, after you have read the considerations article, not as a silent substitute for a VAT registration you already hold.
Name the person who can revert the fallback. A rate change without an owner becomes the next unannounced surprise.
Add the next announced tax change to the same sheet
Shopify posted a second, dated tax move while this VAT gap was still landing on invoices. From 23 October 2026, Shopify will calculate applicable tax on return shipping fees for US returns. Those fees may show $0 tax today. Restocking fees, handling fees, and return fees outside the United States are outside the change.
If a returns app, a 3PL invoice, or a finance export already adds tax on that fee, review the workaround before 23 October so the new calculation does not sit on top of yours. Place one US return with a shipping fee after the cutover and store the same four artefacts you stored for the UK tests.
A shipping-profile or market edit can change a customer you were not looking at. When you add a country or move a SKU between profiles, re-run the threshold pair on the paths you already signed. Peak trading keeps moving during a quiet week, so fold this sheet into the dated gates in A Shopify Black Friday Readiness Checklist for Brands That Already Scale if those UK paths will take November traffic. Sign the walk only when every live EU-to-UK path has a recorded IOR, two test orders, a VAT yes or no, and one named fallback.
Conclusion
You can now list each EU-to-UK shipping path after the 29 September 2026 Shopify Tax change, place test orders above and below £135, record whether VAT still posts when you are importer of record, and write the fallback tax method. The engine follows fulfilment location, and a UK row in Locations is only as real as the stock and the routing rule behind it.
If the sheet still disagrees after a week of tests, because routing, a 3PL, and two tax products all claim the same invoice, book a Shopify stack audit so one team maps which setting owns the VAT line. Theme work will not put 20% back on a cart the tax service has already classified as an import. For a wider discovery conversation, start from contact.
