Yes we are a little overwhelmed with actually getting people signed up. Make a request for more info and I will give you my number.. We can have a brief chat and you will be clear on how we are working.
Topic summary
Feature request to allow UK merchants to integrate Taxamo Assure at checkout to collect EU VAT via IOSS post‑Brexit. Goal: charge VAT at checkout and remit via an intermediary to avoid delivery‑time charges and returns.
Shopify status and guidance:
- Checkout API (needed for Taxamo) is limited to Shopify Plus; no timeline to change. No built‑in IOSS intermediary integration. Third parties must build apps.
- “Registration‑based taxes” can be enabled to calculate local EU VAT and accept an IOSS ID (IOSS = for non‑EU sellers; OSS = for EU sellers).
Workarounds and apps:
- Taxamo: no Shopify plugin (focused on Magento). Custom API possible but complex; one merchant reports non‑Plus implementation via developer.
- Crossborderit (CBIT): IOSS via Sweden; pricing evolved from ~€19.99/mo + €1/order to app ($24/mo) and later reports of €99/mo + 3% on VAT. Early CSV uploads were painful; the Shopify app later smoothed reporting. Mixed reports of customers still being charged VAT; many issues traced to Royal Mail Click & Drop and label/IOSS handling, later improved with IOSS‑marked services.
- Alternatives: Avalara (costly full service), VAT Digital, Zonos (adds % fee), Eurora, EAS EU Compliance (no monthly fee; €1.25/txn + €6 invoice fee >€30). Several merchants plan to switch to EAS.
Operational notes:
- IOSS applies to consignments ≤ €150 and covers VAT only (not duty). Keep IOSS ID off labels; ensure RM Click & Drop uses IOSS services. Germany also requires VerpackG/LUCID packaging registration.
Outcome: No native Shopify–Taxamo integration; viable paths are registration‑based taxes + third‑party IOSS services. Discussion remains open (e.g., EAS support for sole traders).
We do not have any contract. If you want to change to another provider you will need to file for a change of intermediary but Crossborderit does not tie you into anything.
It takes 1-3 days to get a number. You will receive a message from the Swedish tax authorities. There will be a manual upload for the short term into our system but we have a Shopify extension in beta right now so hopefully it can go automated in about a month.

feel free to sign up.
An integration between Shopify and Taxamo is so necessary right now to help small businesses navigate the new VAT changes. Please add this feature Shopify!

Thank you

The registration process for Cross Border IT was really quick and easy! Now
we just have to wait for our IOSS number and then see what happens after
that.

Can I ask how that will work with Shopify - is there an integration at checkout or do you need to file a daily/weekly report?
Thanks
I have just spoken with Damon at crossborderit. Extremely helpful and it seems very straightforward so I am going ahead with this. Thank you Damon for the clarity, really appreciate it!
I signed up yesterday and got my IOSS number from the Swedish Tax authority today. So far so good

I have just signed up to crossborderit.
I am unsure what the update from Shopify will look like with regard to the automatic tax update. My only hope is that they do not apply VAT to ALL countries as it isn’t applicable to ALL countries when selling from the UK. We shall have to wait and see what this looks like after July 1st. Perhaps shopify could hop back in here to let us know about the automatic tax update for the VAT in the EU?

I looked at this and was quite alarmed to see two false statements in the first paragraph, I stopped reading here as I lost complete faith in your product. I suggest you fix this
for the record - I don’t accept the solution the member of the Shopify Staff has given to this issue

I see the confusion and will fix the web copy but to clarify.
The idea of the IOSS is that the merchant collects the taxes on behalf of the customer. So it can be paid in the buying country. Yes, that is confusing and I will clarify it.
The second statement I will also modify. The meaning here is for IOSS of course there are both duties and taxes for high-value shipments but it falls out of the IOSS Protocol.
I will fix the web copy. Thank you for calling it out.
One more comment on there were no taxes levied below 150 there was a variable De Minimis in each country. Taxes were not levied on that but not the De Minimis for Duties is up to 150. So that is confusing and I will find a new way to Phrase it but neither of these statements are wholly false more so simplifications.
Thanks for all of the info on this thread. This whole thing is just so frustrating! I just thought that I would add that I have just got off of a call with HMRC and was told that they have been advised that there should be a way to register for IOSS on the gov.uk website tomorrow! Apparently it can’t go live until the new tax arrangement does! Here’s hoping! If not, Crossborderit sounds like a good option in the meantime.
