Do I need to register for EU OSS?

Who this is for

If you're a small EU business — a solo founder, freelancer, or indie shop — selling to customers in other EU countries, "do I need to register for OSS?" is a surprisingly hard question to get a straight answer to. Most guides either assume you already know the jargon or bury the one rule that decides it.

This page walks the actual decision, one question at a time. Each step tells you whether you can stop reading (the rule doesn't apply to you) or move to the next question. At the end, if it does apply, there's a free calculator that tracks the threshold for you.

This is a self-check aid, not tax advice. See the disclaimer at the bottom, and verify anything before you file or invoice.

1. Are you selling to consumers (B2C), or to businesses (B2B)?

The €10,000 threshold and OSS are about B2C sales — sales to private consumers who don't give you a valid VAT number.

If your customer is a VAT-registered business in another EU country, that sale is normally handled under the reverse charge mechanism instead: you don't charge VAT, and the buyer accounts for it in their own country. Different rules, different paperwork — the threshold on this page isn't the one that governs it.

Selling only B2B? The €10,000 distance-selling threshold doesn't apply to you. Selling to consumers (or a mix)? Keep going — count only the B2C part.

2. Are your customers in other EU countries?

The threshold only counts cross-border sales — sales to consumers in EU member states other than the one you're established in.

Sales to consumers in your own country don't count toward it at all; those are ordinary domestic sales under your national VAT rules. Sales to customers outside the EU are a separate export question, also not part of this calculation.

Only selling domestically? This threshold doesn't apply. Selling cross-border within the EU? Keep going — count only those cross-border B2C sales.

3. Are you selling goods, or digital/telecoms/broadcasting (TBE) services?

The €10,000 threshold covers cross-border B2C sales of goods and of TBE services — telecommunications, broadcasting, and electronically supplied services. In practice, for a small online seller, TBE services means things like ebooks, SaaS subscriptions, online courses, downloadable software, and other automated digital products.

Other kinds of services (say, consulting delivered by a human) follow different place-of-supply rules and aren't what this threshold governs. If everything you sell cross-border is goods or TBE services, you're in scope.

Selling goods or TBE services cross-border? Keep going. Selling only other services? This particular threshold isn't your rule — check the place-of-supply rules for your service type.

4. Are any of them excise goods (alcohol or tobacco)?

This is the first edge case that catches people out. Excise goods — alcohol and tobacco — don't get the €10,000 threshold at all. Destination-country VAT applies to those cross-border B2C sales from the very first sale, regardless of value.

So if you sell wine, spirits, beer, or tobacco to consumers in other EU countries, don't wait for a threshold to be crossed — the destination-country treatment starts immediately.

Selling excise goods cross-border? Destination-country VAT applies from sale #1 — the €10,000 threshold doesn't buy you any headroom. Not selling excise goods? Keep going.

5. Are you established in a single EU member state?

The €10,000 simplification is designed for sellers established in one member state. If you're VAT-registered or hold stock in more than one EU country — the classic example is a multi-country Amazon FBA setup where your inventory sits in warehouses across several member states — the threshold generally doesn't apply to you, and you're into destination-country VAT territory regardless of volume.

For most small sellers dispatching from a single home country, this is a formality — you're established in one place, so the threshold applies. But if you hold foreign stock, this is where the simple version of the rule stops fitting your situation, and it's worth talking to an accountant.

Established in one member state? Keep going — you're at the last question. Established or holding stock in several? The €10,000 threshold likely doesn't apply; expect destination-country VAT regardless of total.

6. Is your combined cross-border B2C total over €10,000?

This is the question the whole rule turns on. Add up all your cross-border B2C sales of goods and TBE services across every other EU country — it's one combined EU-wide total, not a per-country figure. Then check it against both:

• your previous calendar year's total, and
• your current calendar year's running total.

While that combined total stays at or below €10,000, you can charge your home country's VAT rate on these sales — no OSS registration required. The moment your current-year running total goes over €10,000, that transaction — and every one after it for the rest of the year — must be taxed at the destination country's VAT rate, typically declared through the One Stop Shop (OSS) rather than registering for VAT in each country separately.

Two things people get wrong here: it's not a per-transaction test, and it's not a "did I sell more than €10k into one country" test. It's a single cumulative EU-wide sum, and it can flip in the middle of a year — the exact transaction that pushes you over is the one where your VAT treatment changes.

Three special cases to keep in mind

Even once you know the threshold applies, a few situations change how you count:

Non-euro currencies

If you track sales in a currency other than the euro, use your country's fixed national-currency figure for the threshold (for example, Poland uses a fixed 42,000 PLN) rather than converting today's sales at today's exchange rate. The legal threshold is a fixed historical conversion, not a live spot-rate one.

Northern Ireland

Goods sales between the EU and Northern Ireland run under a separate UK/HMRC-administered threshold (also €10,000 / £8,818, goods only), not the EU's Article 59c threshold this guide is about. If Northern Ireland is part of your picture, treat it as its own calculation.

What changes on 1 January 2027

Under the EU's "VAT in the Digital Age" (ViDA) package, from 1 January 2027 the €10,000 threshold will only count distance sales dispatched from your own home member state. Sales shipped from stock you hold in another EU country (e.g. a fulfilment warehouse) will stop counting toward it. If you dispatch from a single EU country, this doesn't change anything for you — but it's worth knowing the rule is narrowing, not widening. See what changes on 1 January 2027 for the full before/after.

So — do you need OSS?

Putting the six questions together: you're most likely in scope of the €10,000 threshold (and OSS once you cross it) if you're an EU business established in a single member state, selling goods or TBE services to consumers in other EU countries, none of them excise goods. Below the threshold you charge home-country VAT; cross it and destination-country VAT applies via OSS from that transaction on.

The one moving part is that running total — so let the tool track it:

• 3 worked examples of how the running total plays out, transaction by transaction.

Disclaimer

This guide and the calculator are a self-check aid, not tax advice or a filing system. They don't model VAT-registered establishments in multiple member states (including sellers who hold stock in more than one EU country, e.g. multi-country Amazon FBA), marketplace deemed-supplier rules, or every goods-vs-services carve-out. Excise goods (alcohol, tobacco) don't get this threshold at all — destination-country VAT applies from the first sale regardless of value. If you track sales in a non-euro currency, use your country's fixed national-currency figure rather than a live conversion. Northern Ireland runs a separate UK/HMRC-administered threshold. Verify anything against the EU Commission's OSS guidance or an accountant before filing or invoicing.
