The Reverse Charge Mechanism in VAT

What the reverse charge is

Under the normal VAT rule, the seller charges VAT on an invoice, collects it from the buyer, and remits it to the tax authority. The reverse charge mechanism flips that responsibility: the seller does not charge VAT, and the buyer accounts for it directly on their own VAT return — both as output VAT (as if they had charged themselves) and as input VAT (which they typically recover at the same time, often netting to zero).

The reverse charge is not optional. Where the law applies it, the invoice must follow the reverse-charge rules, and the buyer must self-assess. Getting this wrong is one of the most common compliance mistakes for businesses dealing with cross-border services or specific domestic sectors.

Why the rule exists

Two practical problems pushed VAT systems towards reverse charge:

Cross-border services. If a consultant in Country A invoices a business in Country B, requiring the consultant to register, charge, and remit Country B's VAT would be administratively painful and would force every supplier to know every other country's rules. Reverse charge solves this by saying: the buyer in Country B handles the VAT under its own domestic rules.
Fraud-prone domestic sectors. In sectors where missing-trader fraud has been a problem (carbon credits, electronics, scrap metal, telecom services, construction in some jurisdictions), domestic reverse charge cuts off the route by which a fraudster collects VAT from a customer and disappears without remitting it. With no VAT collected in the first place, that route closes.

When the reverse charge applies

The exact triggers vary by country, but three patterns cover most situations:

1. Cross-border B2B services into a VAT country

Most VAT regimes require business buyers to self-assess VAT on services received from suppliers outside the country. The supplier issues an invoice without VAT, often noting the buyer's VAT number and a reference to reverse charge. The buyer accounts for VAT in their next return.

2. Intra-EU supplies of goods to a VAT-registered business

Inside the EU, when a business in one member state sells goods to a VAT-registered business in another member state, the sale is zero-rated for the seller and the buyer accounts for VAT in their own country under the reverse charge. The seller verifies the buyer's VAT number through the VIES system before zero-rating the supply.

3. Specific domestic sectors

Several countries apply domestic reverse charge to particular sectors as an anti-fraud measure. Common examples include construction services between contractors, supplies of certain electronics, scrap metals and recyclables, and emission certificates. The list is country-specific and changes over time.

How the invoice should look

A reverse-charge invoice typically shows:

Both parties' full names, addresses, and VAT identification numbers (where applicable).
The net amount only — no VAT line.
An explicit note such as "Reverse charge — VAT to be accounted for by the recipient" or, in EU contexts, a reference to Article 196 of the VAT Directive (for general B2B services) or to the equivalent national provision.
For intra-EU goods supplies: a note confirming the supply is zero-rated as an intra-Community supply.

The exact wording is sometimes prescribed by national law. Where it is not, plain language is acceptable as long as it makes clear that the buyer is responsible for VAT.

Worked example: a UK consultant invoicing a German company

Suppose a UK-based consultant invoices a German VAT-registered company €5,000 for advisory work delivered remotely.

The consultant does not charge UK VAT — the place of supply for B2B services is generally where the customer is established.
The consultant does not register for VAT in Germany either; the German customer self-assesses.
The invoice shows €5,000 net, the consultant's UK VAT number, the customer's German VAT number (which the consultant has verified), and a clear "reverse charge" note.
On the German company's next VAT return, it declares €5,000 in output VAT (€950 at the German 19% standard rate) and, assuming the service is used for fully taxable activity, the same €950 as input VAT — a wash.
If the German company carried out exempt activity instead (so it could not recover input VAT), the €950 would be a real cost. This is why reverse charge is not always tax-neutral, even though it usually is.

Decision points before applying reverse charge

Before zero-rating an invoice on the assumption that reverse charge applies, work through these questions:

Is the customer a business? Reverse charge is overwhelmingly a B2B mechanism. Sales to consumers usually require the supplier to charge VAT under the destination country's rules (in the EU, often via OSS or IOSS — see VAT on digital services).
Is the customer in a different VAT jurisdiction? Cross-border B2B services and intra-EU goods supplies are the classic cases. Domestic services are normally taxed at the supplier's local rate, with the exception of the sector-specific domestic reverse charges noted above.
Have you verified the customer's VAT number? Inside the EU, you must check the buyer's VAT identification number before zero-rating an intra-Community supply of goods. Without a valid number, the reverse-charge route is not available and you may have to charge local VAT.
Is the supply within scope of a domestic reverse-charge regime? If you operate in construction, scrap, electronics, or telecoms, check whether your country applies a sector reverse charge between businesses.
Does the invoice carry the right wording? Tax authorities have rejected reverse-charge treatment because the invoice did not include the required note. The wording is cheap insurance.

Common mistakes

Treating B2C cross-border sales as reverse charge. A consumer cannot reverse-charge themselves. For B2C distance sales of goods or digital services within the EU, see the OSS and IOSS rules instead.
Forgetting to self-assess. The buyer's VAT cost is often zero on a netted return, but failing to declare the reverse-charge entries at all is still a procedural breach and can attract penalties.
Charging VAT anyway "to be safe". If reverse charge applies, charging local VAT is wrong, and the customer may not be able to recover it. Worse, the supplier may have over-collected VAT it cannot clean up easily.
Skipping VIES validation. If the customer's VAT number turns out to be invalid at the time of supply, the seller can be assessed for VAT on what it treated as a zero-rated supply.
Confusing zero-rated and reverse-charge supplies on the return. Both look like 0% on the invoice, but they are reported in different boxes.
