For Irish-based online sellers shipping to customers across the EU, VAT is rarely simple — and getting it wrong is one of the most expensive mistakes a growing ecommerce business can make.
Why Ecommerce VAT Trips Up Even Careful Founders
Most Irish ecommerce founders start out registered for VAT in Ireland and assume that covers them. It doesn’t — not once sales cross into other EU member states. The rules that determine where VAT is due, at what rate, and under which scheme change the moment a business starts selling cross-border, and Revenue’s enforcement of these rules has tightened considerably as EU-wide reporting has become more joined up.
The good news is that the framework, once understood, is manageable. The two things that matter most are knowing your registration thresholds and knowing whether the One Stop Shop (OSS) scheme is right for your business — and both of those depend heavily on which platform, or mix of platforms, you’re actually selling through.
Step One: Categorise Your Sales Channels
Before any registration decision can be made, you need to know which category each of your sales channels falls into. VAT treatment is not the same across Shopify, Amazon, eBay and Etsy — the platform’s role in the transaction changes who is legally responsible for charging and remitting VAT.
Your Own Storefront: Shopify, WooCommerce, BigCommerce
On a self-hosted or owned storefront, you are the vendor of record for every sale. There is no intermediary collecting VAT on your behalf. This means your checkout needs to determine the customer’s location, apply the correct VAT rate, and your business needs to report that sale under either standard Irish VAT or the OSS scheme, depending on where the buyer is based. Full responsibility — and full liability if it’s done incorrectly — sits with you.
Online Marketplaces: Amazon, eBay, Etsy
Marketplaces are treated differently under EU ‘deemed supplier’ rules introduced in 2021. For certain transactions — mainly consignments valued under €150 imported from outside the EU, and sales by non-EU sellers to EU consumers — the marketplace itself is deemed to be the supplier for VAT purposes and collects and remits the VAT instead of you. Critically, this does not apply to every transaction: EU-based sellers shipping EU-held stock to EU consumers are generally still responsible for their own VAT, even when the sale happens through Amazon or eBay. Assuming the marketplace ‘has it covered’ across the board is one of the most common — and costly — misconceptions we see.
Multi-Channel and Hybrid Sellers
Most growing Irish ecommerce businesses end up selling through more than one channel — a Shopify store for brand and margin, plus Amazon or Etsy for reach. This is entirely normal, but it means your VAT reporting has to be built channel-by-channel: some sales collected and remitted by the marketplace, others fully your responsibility, all feeding into a single, reconciled VAT position. Trying to manage this with a single blended assumption across all channels is where errors creep in.
Irish VAT Registration Thresholds
Ireland applies two separate thresholds depending on what you’re selling. Once your turnover in any continuous 12-month period exceeds the relevant figure, VAT registration in Ireland becomes mandatory.
| Registration trigger | Irish threshold |
|---|---|
| Supply of services | €42,500 |
| Supply of goods | €85,000 |
Many ecommerce sellers combine goods and services (for example, a product business that also sells digital add-ons or consulting), which is where the calculation gets more complex. It’s worth reviewing your revenue mix at least quarterly rather than waiting for a year-end surprise.
Which Registration Applies — and at What Revenue Level
Once you know your channel mix, the next question is which registration(s) you actually need. For most Irish ecommerce sellers, it isn’t one registration — it’s a combination that builds up as revenue and reach grow.
- Irish domestic VAT registration — required once you cross €42,500 (services) or €85,000 (goods) in Irish-based turnover. This is your baseline registration regardless of where else you sell.
- EU OSS (Union scheme) — required once your total cross-border B2C sales into other EU member states exceed €10,000 in a calendar year. Below that figure you may continue charging Irish VAT on those sales; above it, OSS (or local registration in each country) becomes necessary.
- Import One-Stop Shop (IOSS) — relevant if you import and sell goods valued at €150 or less directly to EU consumers from outside the EU. IOSS lets you charge VAT at the point of sale and avoid customers being hit with surprise import VAT on delivery.
- Local country VAT registration — triggered independently of OSS the moment you store stock in another EU country, most commonly through Amazon FBA or a pan-EU fulfilment network. OSS covers the sale; it does not cover the stock movement or the fact that you now have a taxable presence in that country.
- Intrastat — a separate statistical filing once your intra-EU goods movements pass the relevant threshold, regardless of your VAT or OSS status (covered in more detail below).
The practical implication: a Shopify-only seller under €10,000 in EU sales might need nothing beyond standard Irish VAT. The same business, once it starts using Amazon FBA with stock held in Germany, could simultaneously need Irish VAT, OSS, a German VAT registration and Intrastat reporting — four obligations arising from one growth decision. This is precisely why channel and fulfilment choices should be reviewed with your accountant before scaling, not after.
The One Stop Shop (OSS) Scheme, Explained
The OSS scheme was introduced to simplify EU VAT for cross-border sellers, and for most Irish ecommerce businesses selling B2C into other member states, it’s the better option than registering for VAT in every country you sell into.
- One registration, filed through Revenue in Ireland, covers your VAT obligations across all EU member states where you sell to consumers.
- You charge the VAT rate of the customer’s country, not Ireland’s, on qualifying cross-border B2C sales.
- Returns are filed quarterly, consolidating all EU sales into a single OSS return rather than dozens of local filings.
- OSS applies once your total cross-border B2C sales into other EU states exceed €10,000 in a calendar year (a separate, EU-wide distance-selling threshold from the Irish domestic thresholds above).
The trade-off is that OSS requires precise record-keeping: you need to track the customer’s country for every sale, apply the correct local VAT rate, and reconcile it all at quarter-end. This is where a lot of founders — perfectly capable of running the commercial side of the business — start to lose time and accuracy.
Don’t Forget Intrastat
If your ecommerce business moves physical goods across EU borders (holding stock in an overseas fulfilment centre is a common trigger), you may also have an Intrastat reporting obligation, separate from your VAT return. Intrastat tracks the physical movement of goods between EU member states for statistical purposes, and thresholds and filing frequency depend on your volume of intra-EU trade. It’s a common blind spot for sellers using pan-EU fulfilment models, since the obligation exists independently of whether you’re OSS-registered.
The Most Common Compliance Mistakes We See
- Registering for VAT in Ireland but continuing to charge Irish VAT on cross-border B2C sales that should carry the customer’s local rate under OSS.
- Missing the €10,000 EU-wide distance-selling threshold because it’s tracked separately from the Irish domestic thresholds.
- Treating marketplace sales (Amazon, Etsy, eBay) as fully compliant by default — deemed supplier rules mean the marketplace may account for VAT on your behalf, but only for certain transaction types.
- Overlooking Intrastat obligations when stock is held or moved through overseas warehouses.
- Reconciling VAT annually instead of monthly, which turns small errors into large, hard-to-unwind ones.
Case Studies: Three Irish Sellers, Three Different Paths
Case Study 1 — Emerald Home Goods (Shopify, direct-to-consumer)
Emerald Home Goods sells homeware exclusively through its own Shopify store, shipping from a single warehouse in Dublin. As an owned-storefront seller, Emerald is the vendor of record for every transaction. Once EU sales (outside Ireland) passed €10,000 in a calendar year, Emerald registered for OSS through Revenue, allowing it to charge the correct local VAT rate for each EU customer through a single quarterly return rather than registering separately in each country. Because all stock stays in Ireland, no Intrastat or additional local VAT registrations were triggered — OSS alone covered the cross-border position.
Case Study 2 — CelticTech Gadgets (Amazon FBA, pan-EU fulfilment)
CelticTech Gadgets sells electronics accessories through Amazon, using Amazon’s pan-EU fulfilment network to hold stock in Germany and Poland for faster delivery. Because Amazon is the marketplace for these sales, deemed supplier rules meant Amazon collected and remitted VAT on qualifying transactions. However, storing stock in Germany and Poland created a taxable presence in each country, independent of Amazon’s role — meaning CelticTech needed local VAT registration in both, alongside its existing Irish VAT registration, and a monthly Intrastat filing to report the stock movements. OSS was not sufficient on its own because it doesn’t cover the cross-border movement of a seller’s own stock.
Case Study 3 — Aisling Crafts (Etsy and eBay, hobby to business)
Aisling Crafts began as a part-time Etsy shop selling handmade candles and grew into a registered business within eighteen months. Early sales stayed under both the Irish threshold and the €10,000 EU OSS threshold, so no VAT registration was required. As UK and EU orders grew, Aisling crossed the OSS threshold first, followed by the Irish domestic threshold shortly after. Because the business tracked its channel-by-channel revenue from the outset, both registrations were completed proactively rather than in response to a compliance query from Revenue — avoiding any late-registration penalties or backdated VAT exposure.

Frequently Asked Questions
Only once your turnover exceeds the relevant Irish threshold — €42,500 for services or €85,000 for goods in any continuous 12-month period. Below that, registration is optional, though some businesses register voluntarily to reclaim VAT on costs.
Possibly. Amazon’s deemed supplier rules only apply to specific transaction types — mainly low-value imports and non-EU seller sales. If you’re an Irish seller with EU-held stock, you very likely still carry the VAT obligation yourself, and may need OSS or local registration regardless of Amazon’s involvement.
No. OSS is an additional scheme for reporting cross-border B2C sales into other EU states. You still need standard Irish VAT registration once you exceed the domestic threshold, and OSS sits alongside it for EU sales beyond the €10,000 distance-selling threshold.
Holding stock abroad — commonly through Amazon FBA or a European 3PL — generally creates a local VAT registration requirement in that country, along with an Intrastat obligation, regardless of your OSS status. This is one of the most frequently missed obligations for scaling sellers.
OSS returns are filed quarterly. Intrastat filing frequency depends on your volume of intra-EU trade, but is typically monthly once the threshold is triggered.
Penalties can include interest and fixed penalties on late or incorrect VAT, backdated liabilities if registration should have happened earlier, and in more serious cases, Revenue audit exposure. The cost of correcting a multi-country VAT position retrospectively is almost always higher than the cost of setting it up correctly from the start.
