EU VAT and OSS for Online Sellers: The €10,000 Rule Explained

The rule in one line: once your cross-border sales to consumers in other EU countries exceed €10,000 in a year, you must charge VAT at the customer's country rate instead of your own — and the One Stop Shop (OSS) lets you declare all of it through a single registration in your own country instead of registering in each destination.

Below the threshold

If you are established in one EU country and your total cross-border B2C sales of goods and digital services to all other EU countries stay under €10,000 per calendar year, you can keep charging your home country's VAT rate on those sales and account for it domestically. This is a simplification for small sellers, and it is EU-wide and cumulative — not €10,000 per country.

You may also opt in to destination-rate VAT voluntarily before you hit the threshold, which some sellers do to avoid a mid-year switch.

Above the threshold

Once you pass it, each sale is taxed at the customer's country rate. You then have two options:

1. Register for VAT in every destination country. Accurate, and administratively miserable.
2. Register for OSS in your own country. One registration, one quarterly return covering all your EU cross-border B2C sales, one payment — your tax authority distributes it. This is what almost everyone should do.

OSS does not replace your domestic VAT return; it sits alongside it for the cross-border portion.

What this means for your pricing

VAT rates across the EU range from the high teens to over 25%. That has a direct consequence people miss:

• If you show the same gross price everywhere, your net revenue differs by country. The same €50 product nets you noticeably less in a high-rate country than a low-rate one.
• If you show the same net price everywhere, your gross prices differ, and comparison-shopping customers will notice.

Neither is wrong. Choosing by accident is wrong. Decide, then price deliberately.

IOSS: for goods imported into the EU

If you ship goods from outside the EU to EU consumers, the Import One Stop Shop applies to consignments with an intrinsic value up to €150. Under IOSS you charge EU VAT at the point of sale and the parcel clears customs without VAT being collected at the border.

Why this matters commercially, not just administratively: without IOSS, your customer gets a bill at the door — import VAT plus a courier handling fee. That is the single most reliable way to turn a delivery into a refused parcel and a bad review. If you sell into the EU from the Gulf, the UK or anywhere else, IOSS is a conversion feature, not just a tax scheme. See cross-border selling from the Gulf to Europe.

Above €150, normal import procedures apply — duty and import VAT at the border.

Practical setup

1. Track your cross-border total continuously, not at year end. You need to know when you are approaching €10,000.
2. Configure destination VAT rates in your store before you need them, and verify a sample checkout per country.
3. Keep the evidence. OSS requires you to identify the customer's location using accepted evidence and keep records for the required retention period.
4. File quarterly, on time. OSS deregistration for repeated late filing is a real and avoidable problem.
5. Handle refunds correctly, at the same rate as the original sale.

Frequently asked questions

Is the €10,000 threshold per country or in total?

In total, across all EU countries, per calendar year — and it includes digital services as well as goods.

Does OSS cover B2B sales?

No. OSS is for B2C. B2B intra-EU supplies generally use the reverse charge, with the customer's VAT number validated.

Do I still need my domestic VAT registration?

Yes. OSS covers the cross-border B2C portion only.

What if I sell through a marketplace?

Marketplaces are often deemed the supplier for VAT purposes on certain sales, which changes who accounts for it. Check per platform.
