Switching Amazon VAT provider is not just a price decision. For one UK Amazon seller, the move away from a marketplace-linked, low-touch VAT service to hellotax meant regaining control over multi-country VAT, clearing confusion about OSS, and getting real support instead of just automated filings.
This case study shows how a UK-based Amazon business compared Amazon VAT service providers, switched to hellotax, and now benefits from a stable, transparent VAT setup across Europe.
The Client: UK Amazon Seller With Multi-Country EU VAT
The client is a UK private limited company that:
-
Sells wholesale B2B in the UK
-
Sells retail B2C in the UK and EU
-
Uses Amazon as the main sales channel and is planning to grow its own webshop in the future
Operational setup:
-
Location: United Kingdom
-
Sales channels: Amazon (primary) + own website (planned expansion)
-
Stock: Based in the UK; goods shipped to Amazon warehouses in France
-
VAT footprint: Already registered for VAT in
-
UK (handled in-house)
-
Germany, France, Italy, Poland and Czech Republic (for EU sales)
-
Until recently, their EU VAT compliance was handled by a third-party VAT provider integrated via an Amazon programme. When that programme changed and support became more limited, the seller realised they needed a more reliable and future-proof Amazon VAT provider — not just the cheapest or most closely “plugged into” Amazon.
They were particularly interested in understanding and potentially using the One Stop Shop (OSS), and in keeping multi-country VAT filings under control without spending hours chasing tax letters and deadlines.
The Challenge: When a “Cheap” Amazon VAT Provider Stops Being Enough
The main issue was simple: the previous provider was optimised for volume and low fees, not for long-term VAT strategy.
With the marketplace-linked VAT service running their Amazon VAT compliance, registration and filing looked cheap and convenient. But once the programme was adjusted and support became less personalised, several problems emerged:
-
No clear long-term plan
The client had VAT numbers in Germany, France, Italy, Poland and Czech Republic, but there was no strategic overview of:-
Which returns were really needed.
-
How future OSS use would interact with those VAT IDs.
-
What would happen if Amazon changed logistics or programmes again.
-
-
Limited visibility and support
Most of the service was automated and ticket-based. When you are switching Amazon VAT provider or asking strategic questions (like “Do we still need all these VAT numbers if we move to OSS?”), you quickly hit the limits of a low-touch service. -
Price-first model, risk-second
The previous setup was attractive on price, but offered:-
Minimal proactive advice.
-
Limited support on tax letters and audits.
-
Little help if Amazon or tax offices asked for detailed documentation.
-
-
Programme dependency
Their VAT setup depended heavily on a specific marketplace programme that could be changed or discontinued at any time. When this happened, they were left searching for a new solution on short notice.
For a UK business already registered in several EU countries and considering OSS, comparing Amazon VAT compliance services purely on price was no longer acceptable. They needed a provider that could:
-
Take over existing VAT numbers and filings smoothly
-
Offer clear, human explanations
-
Support future changes (OSS, new marketplaces, additional countries) without rebuilding everything from zero
The Solution: Switching Amazon VAT Provider to hellotax
hellotax proposed a solution focused on stability, transparency and expert support, rather than just another “cheap” Amazon VAT package.
1) VAT Health Check and Provider Comparison
First, hellotax performed a structured VAT review:
-
Confirmed existing VAT registrations in Germany, France, Italy, Poland and Czech Republic
-
Clarified filing frequencies and any open obligations
-
Analysed how Amazon warehousing in France affected domestic vs. cross-border VAT
-
Mapped where OSS could simplify things in the future and where local VAT returns would still be mandatory
This gave the client a clear comparison:
-
Old setup: Low-price, marketplace-linked, little strategic input
-
New setup with hellotax: Multi-country perspective, OSS-aware, with both automation and local experts
2) VAT Takeover in Five EU Countries
The client chose the hellotax VAT Compliance Service – 5 Countries Package, covering:
-
Germany
-
France
-
Italy
-
Poland
-
Czech Republic
hellotax handled the VAT takeover, including:
-
Getting access to local tax portals where possible
-
Aligning historical filings and periods
-
Checking whether any returns were missing or needed adjustments
-
Ensuring that monthly, quarterly and annual returns would be filed on time going forward
The VAT takeover typically takes 4–6 weeks, during which hellotax coordinates with local tax offices and ensures there are no gaps between the previous provider and hellotax.
3) Clean, Ongoing VAT Filings and Intra-Community Reporting
Once the takeover was complete, hellotax:
-
Took over ongoing VAT returns (monthly, quarterly, yearly as applicable)
-
Managed intra-community supplies and stock transfers reporting where required
-
Ensured that any small additional VAT payments (beyond what Amazon remits directly in certain countries) were calculated correctly and paid on time
Instead of worrying whether filings had actually been submitted in each country, the client could now check everything in one place.
4) Tax Letter Inbox and Real People Behind the Software
One of the key differences when switching Amazon VAT provider to hellotax was how communication with tax offices is handled.
With hellotax, the client benefits from:
-
Tax Letter Inbox
-
hellotax receives official letters from tax authorities
-
Letters are translated into English
-
They are sorted by country and urgency
-
-
Local VAT experts
-
Country-specific questions are answered by people who know the local rules and language
-
The client does not have to hunt for external accountants just to respond to a German, French or Italian letter
-
-
Dedicated account manager
-
One main point of contact coordinates everything
-
Questions about OSS, future expansion or additional countries are handled in a structured way
-
5) Future-Proofing: OSS and Expansion Options
The client is particularly interested in using the One Stop Shop (OSS) for cross-border B2C sales.
hellotax provided:
-
Clear explanation of when OSS can be used and what it covers
-
Clarification that:
-
Domestic sales from stock in France (e.g. FR warehouse to FR customers) must stay in local French VAT returns, not OSS
-
OSS is ideal for cross-border B2C sales within the EU, especially for future channels beyond Amazon
-
With this information, the client can plan future channels and markets without being locked into a single marketplace-linked provider again.
If you want to understand what Amazon’s own VAT tools actually do (and where their responsibilities stop), Amazon’s official help pages on VAT Calculation Service and VAT invoicing are a useful reference. They explain how Amazon calculates VAT and issues invoices, but also clarify that sellers remain responsible for correct VAT registration and reporting in each country.

Transparent pricing (monthly or yearly) without surprises and hidden add-ons for basic tasks
Stable ongoing filings in all registered countries, with clear due dates and status in the dashboard

Why Switching Amazon VAT Provider Matters for UK Sellers
For UK sellers trading on Amazon and other marketplaces, switching Amazon VAT provider can be a crucial step in reducing risk and hidden costs.
This case highlights several broader lessons:
-
Marketplace-linked programmes are convenient but limited
When a marketplace changes a partner or discontinues a service, you might suddenly need a new provider with little notice. -
Price-only decisions are risky
Cheap providers often rely on high automation and low human involvement. This works until something unusual happens: an audit, a tax letter, a change in how Amazon moves your stock. -
UK sellers need EU-wide thinking
With stock in EU warehouses (e.g. France) and sales to multiple EU countries, you need a VAT partner that can:-
Cover all relevant countries
-
Explain how OSS fits with local VAT
-
Support both Amazon and non-Amazon channels
-
By comparing Amazon VAT compliance services carefully and choosing a partner like hellotax, UK sellers can stabilise their EU VAT setup and plan growth with confidence.

Lessons Learned (You Can Apply Today)
You can apply the same logic if you are considering switching Amazon VAT provider:
-
Do not choose on price alone. The cheapest Amazon VAT provider may cost more later through penalties, corrections and extra advisory fees.
-
Check coverage. Make sure your provider covers all countries where Amazon stores your stock and where you sell.
-
Ask about OSS and local VAT. You need a clear answer on when OSS applies and when local VAT returns remain mandatory.
-
Look for a real takeover process. A proper VAT takeover should include a health check, historical review and local tax office coordination.
-
Insist on human support. Automation is great, but you also need local VAT experts who can help with letters, audits and special cases.
-
Think beyond Amazon. If you plan to add Shopify, your own website or other marketplaces, choose a provider that can handle all channels under one system.
-
Use a checklist when comparing providers. When switching Amazon VAT provider, look at coverage, automation, compliance processes, support and transparent pricing — not just the headline fee.
