The General Rule: Article 44 of the VAT Directive
The legal foundation for B2B cross-border services is Article 44 of EU VAT Directive 2006/112/EC, which states that the place of supply for services rendered to a taxable person is the place where the customer is established. In practice, this means:
- A French graphic design agency selling design work to a German GmbH: place of supply is Germany
- A Polish software house selling development services to a Dutch BV: place of supply is the Netherlands
- A Spanish law firm advising an Italian SRL: place of supply is Italy
In each case, the buyer's country is responsible for the VAT — and under Article 196, the buyer (not the seller) must account for that VAT via the reverse charge mechanism.
This is the general rule and covers the substantial majority of B2B services: consulting, software development, accounting, legal services, digital marketing, SaaS subscriptions, training, IT support, and most professional services.
What to Write on Your Invoice
An invoice for a cross-border B2B service subject to reverse charge must include specific wording to be legally valid. The standard annotation required across EU member states is:
Reverse charge — VAT 0% — Article 196 VAT Directive
Or in local language equivalents:
- German: Steuerschuldnerschaft des Leistungsempfängers (§13b UStG) — Umkehrung der Steuerschuld
- French: Autoliquidation de la TVA — Article 196 de la Directive TVA
- Dutch: Btw verlegd — Artikel 196 BTW-richtlijn
- Polish: Odwrotne obciążenie — art. 196 Dyrektywy VAT
In addition to the reverse charge annotation, the invoice must include:
| Required element | Example |
|---|---|
| Your VAT number | FR 12 345 678 901 |
| Customer's VAT number (validated via VIES) | DE 123 456 789 |
| Invoice date and unique sequential number | INV-2026-0047 |
| Description of services | Software development services, March 2026 |
| Net amount (no VAT) | €8,500.00 |
| Zero VAT line | VAT: €0.00 (reverse charge) |
| Statutory annotation | "Reverse charge — VAT 0% — Article 196 VAT Directive" |
Many EU countries also require you to report reverse charge B2B sales in a separate EC Sales List (European Communities Sales List), submitted monthly or quarterly. In Germany this is the Zusammenfassende Meldung (ZM), in France the DEB/DES, in the Netherlands the ICP-aangifte. Failure to file EC Sales Lists is a common and costly oversight.
Exceptions: When Reverse Charge Does Not Apply
Article 44 is the general rule, but the VAT Directive carves out several categories of services with special place-of-supply rules. These exceptions apply even in B2B transactions:
Real Estate Services — Article 47
Services directly related to immovable property are taxed where the property is located, regardless of where the buyer or seller is established. An Austrian architect designing a building in Croatia charges Croatian VAT. A British-incorporated property management company managing flats in Portugal is subject to Portuguese VAT, even if billing a Spanish corporate client.
Short-Term Hire of Means of Transport — Article 56
Hiring a vehicle for 30 days or less (90 days for vessels) is taxed where the vehicle is put at the customer's disposal. A German car rental company renting a car to a French company from its Munich location charges German VAT.
Restaurant and Catering Services — Article 55
Taxed where the services are physically carried out. A Luxembourg restaurant serving a corporate dinner to a Belgian company's visiting team charges Luxembourg VAT at 17%.
Admission to Events — Article 53
Entry fees to conferences, exhibitions, concerts, and cultural events are taxed where the event physically takes place. Registration for a trade fair in Milan is subject to Italian VAT, even if the buyer is an Irish company.
Passenger Transport — Article 48
Taxed proportionally based on the distances covered in each country. Cross-border rail journeys are a common example.
Proving Business Status: The Importance of VIES Checks
Applying the reverse charge requires you to confirm that your customer is a taxable person — i.e., a VAT-registered business. The process:
- Ask for the customer's VAT number before issuing the invoice
- Validate the number at ec.europa.eu/taxation_customs/vies/
- Save proof of validation: a screenshot with date and timestamp, or use a service that logs VIES results automatically
- Include the validated VAT number on the invoice
If a customer provides a VAT number that returns as invalid on VIES, do not assume a technical glitch and proceed. Contact the customer. If they cannot provide a valid VAT number, you must treat the transaction as B2C and apply your home country's VAT rate (or the destination country's rate if you are OSS-registered).
Common Mistakes That Trigger VAT Audits
1. Missing or incorrect EC Sales List filings. Tax authorities cross-reference EC Sales Lists between countries. If you reported €50,000 of reverse charge sales to a German company but the German company's input tax claim does not match, both companies' returns are flagged.
2. Reverse charge applied to an unregistered customer. If your customer was not VAT-registered at the date of supply, the reverse charge did not apply — you were responsible for the VAT. This error most commonly occurs when a customer's VAT registration was cancelled or suspended.
3. Incorrect service categorisation. Applying Article 44 (general rule) to a service that falls under an exception (Article 47 for real estate, Article 53 for events) results in charging the wrong VAT and filing in the wrong country. This is an audit trigger in both the seller's and buyer's country.
4. Invoicing without the statutory annotation. An invoice for an intra-EU B2B service that does not carry the reverse charge annotation is technically an invalid invoice in most EU member states. The buyer may not be able to use it to support their reverse charge accounting, and you may face penalties for issuing non-compliant invoices.
5. Failing to distinguish B2B from B2C within the same customer base. If you sell SaaS to a mix of businesses and individual consumers in other EU countries, you need robust processes to identify B2B buyers (verified VAT numbers) from B2C buyers (no VAT number) — the VAT treatment is completely different, and a single mixed-up invoice can cascade into a chain of errors.
Summary: Your B2B Cross-Border VAT Checklist
- [ ] Obtain and validate customer VAT number via VIES before each invoice
- [ ] Confirm service type falls under Article 44 general rule (not a special category exception)
- [ ] Issue invoice with net amount, zero VAT, and statutory reverse charge annotation including Article 196 reference
- [ ] Include both your VAT number and the customer's validated VAT number on the invoice
- [ ] Report the supply in your EC Sales List for the relevant period
- [ ] Record the VIES validation result with date and time as audit documentation
- [ ] File EC Sales List on time — penalties apply in most EU countries for late filing
Getting the numbers right on cross-border B2B invoices is the first step — but you also need to know the correct VAT rates for every scenario where the reverse charge does not apply, including mixed B2C sales and domestic transactions.
