Selling to EU Businesses from the UK 2026 — Reverse Charge

This guide covers what is specific to UK sellers when selling to VAT-registered businesses in the EU. For the full reverse charge mechanics — how to process a B2B EU sale, VIES validation steps, invoice requirements, and when reverse charge does not apply — see the shared guide: Selling to EU Businesses — Reverse Charge & Invoicing.

If you are selling to individual consumers, see the B2C guide instead.

GB VAT Numbers Are Not on VIES

This is the most important UK-specific point for B2B sellers.

GB-prefix VAT numbers (Great Britain sellers) are not listed on the EU’s VIES database. If an EU business buyer goes to the VIES lookup tool to validate your VAT number before paying, they will not find you.

This does not prevent the reverse charge from working — but it changes how it works. When a German business buys from a GB-based UK seller:

The EU buyer cannot verify you as an EU VAT-registered entity on VIES (because you are not one)
Instead, the buyer treats the transaction as an import from a third country
The buyer’s customs broker or import agent handles the VAT as import VAT on arrival, rather than “acquisition VAT” (the intra-EU equivalent)
The practical effect on the buyer is the same — they self-account for VAT — but the legal route is different

For your invoicing: you should make clear you are a UK business (not an EU business) and that the buyer should treat the transaction under their standard import procedures for third-country purchases. The reverse charge statement on your invoice (“Reverse charge — customer to account for VAT”) and Article 138 or Article 44/196 reference still apply.

For EU buyers who insist on a VIES validation: explain that GB VAT numbers are third-country tax registrations and are not listed on VIES by design. Provide your GB VAT number for their records and reference the EU’s import VAT rules as the relevant mechanism.

XI-Prefix Numbers (Northern Ireland) Are on VIES

If your business is based in Northern Ireland, the situation is different. Under the Windsor Framework:

Northern Ireland businesses have XI-prefix VAT numbers issued by HMRC
XI-prefix numbers are listed on VIES — EU business buyers can validate them
For goods (not services), NI-to-EU sales are treated as intra-community supplies rather than exports from a third country
The buyer performs an “acquisition” of EU goods, not an import from a third country

This means NI businesses can issue reverse charge invoices citing Article 138 (intra-EU goods supply) in the same way an EU business would, and the EU buyer can validate the supplier’s registration on VIES before paying.

For services supplied from NI to EU businesses, the standard Article 44/196 rules apply — the same as for any non-EU service provider.

UK VAT Return Reporting

Even though you do not charge VAT on B2B EU sales, you must report reverse charge sales on your UK VAT return:

Box 6: Include the net value of the sale in your total value of sales
Box 8: Include the net value in your total value of EU supplies (this box exists specifically for supplies to EU countries)

These are zero-rated exports for UK VAT purposes. They appear on your return but generate no VAT to pay. Missing these from your return is a reporting error — HMRC can identify discrepancies if your Box 8 figure is zero but you are known to have EU business customers.

Northern Ireland note: NI businesses also use Box 8, but the legal characterisation differs — it records intra-EU dispatches rather than third-country exports. The practical return entry is the same.

Step-by-Step: Processing a B2B EU Sale as a UK Seller

The core process (get VAT number → VIES validate → zero-rate invoice → keep records) is described in full in the shared B2B guide. The UK-specific additions are:

When getting the buyer’s VAT number:

If they give you a GB-prefix number, they are a UK business. Charge UK VAT as normal.
If they give you an XI-prefix number, they are a Northern Ireland business. Treat as an EU business for goods.
All other two-letter country codes are EU VAT numbers — validate on VIES.

When validating on VIES:

VIES will not return a result for your own GB VAT number if you look yourself up — this is expected behaviour, not an error
EU business customers who cannot find you on VIES should be directed to treat the purchase as a third-country import

When issuing the invoice:

Include your GB VAT number on the invoice (e.g., GB123456789)
The buyer’s EU VAT number (the full number with country prefix)
The reverse charge statement and the correct Article reference
Your invoice does not need to show £0 VAT — it should show no VAT line at all

When filing your UK VAT return:

Report in Box 6 (total sales) and Box 8 (EU supplies) — see above

Northern Ireland B2B Sales

For Northern Ireland businesses selling goods to EU businesses:

The legal basis is Article 138 intra-EU supply rules, not third-country export rules
Your XI VAT number appears on VIES — buyers can validate you as they would any EU supplier
The customs process is different from GB: NI goods moving to the EU are not subject to the same customs declarations as third-country exports
For NI-to-EU services, the standard Article 44/196 third-country rules apply

NI businesses should be aware that the distinction between goods and services is particularly important — the NI protocol specifically covers goods movements, not services. A NI-based software company selling SaaS to EU businesses uses Article 44/196 (not the intra-EU supply route).

Common UK-Specific B2B Mistakes

Not validating on VIES because “it won’t show my own number.” Your registration not appearing on VIES is normal. Your customers’ EU VAT numbers still need validating.
Not reporting reverse charge sales in Box 6 and Box 8 on the UK VAT return. These are zero-rated, not invisible. Missing them is a filing error.
Treating XI-prefix (NI) numbers as the same as GB numbers. They are legally different — XI numbers are on VIES and operate under intra-EU supply rules for goods.
Accepting a buyer’s word that they are EU-registered. No VIES validation = no reverse charge. Treat as consumer.
Using the wrong Article reference. GB sellers are third-country exporters for goods (Art. 138) and service providers (Art. 44/196). Using intra-EU Article references that do not apply to you can cause problems for the buyer’s compliance team.
