Cross-border VAT disputes: when an ordinary trade becomes a legal risk

The goods were delivered, the invoices were paid and the margins looked reasonable. Months later, a letter arrives: the Dutch tax authorities are reviewing transactions involving one of your suppliers. The concern is not necessarily your bookkeeping. It is whether a business elsewhere in the supply chain has committed VAT fraud — and what your company could reasonably have known about it.

For businesses trading across EU borders, this is a difficult but important distinction. Understanding how these cases develop can help management teams prepare a clearer, more credible response.

How a legitimate business can end up in a VAT investigation

Intra-EU business-to-business supplies of goods can be treated differently for VAT purposes from domestic sales, provided the applicable conditions are met. Fraudsters sometimes exploit that system by arranging chains of transactions in which one trader charges VAT but does not remit it. This is often described as missing-trader or VAT carousel fraud.

The wider chain can contain businesses that traded genuine goods and had no intention of assisting fraud. Nevertheless, investigators may examine their transactions, commercial relationships and available information. The fact that a company appears in the chain is not, by itself, proof that it acted dishonestly.

The key question: what did the company know?

Under EU case law, input VAT deduction may be refused where a business knew, or ought to have known, that the relevant transaction was connected with VAT fraud. But tax authorities cannot simply point to a suspicious chain and treat every participant as culpable. They must establish the relevant fraudulent conduct and the connection to the taxable person’s knowledge or conduct.

That makes timing crucial. A warning sign that seems obvious after an investigation may have looked different when a purchase order was approved. The commercial context at the time deserves careful attention.

Which warning signs justify a closer look?

A low price or a new supplier is not proof of fraud. Several unusual features together, however, may justify asking more questions. Why are goods being resold several times within days? Why has the payment beneficiary changed at the last moment? Why does a delivery route differ from the agreed destination? And does the company proposing the deal appear capable of performing it?

The aim is not to treat every unfamiliar counterparty as a suspect. It is to understand the business rationale before money or goods move. A transaction that nobody inside the company can explain is harder to defend later.

Due diligence should produce evidence, not just ticked boxes

For EU counterparties, the VIES service can help verify the status of a VAT identification number. That is a useful check, but it does not guarantee that the underlying transaction is legitimate. Depending on the risk, companies may also review registration details, payment arrangements, transport documents and the identities of the people giving instructions.

Record not only that a check took place, but what it showed and how any concerns were resolved. A brief note explaining why an unusual price was commercially credible may be more informative than a generic checklist completed after the event.

When the Dutch tax authorities contact your business

An information request is not a finding of fraud. Start by identifying the period and transactions under review. Preserve invoices, emails, contracts, transport records and the evidence of checks made at the time. Coordinate the response across finance, logistics and management so that factual details are verified before anyone offers an explanation.

It is also important to distinguish an administrative VAT dispute from a potential penalty or criminal investigation. The procedure and the rights at stake can be different. Do not assume that an accounting explanation alone will address every legal question.

Where specialist legal advice can make a difference

A tax lawyer experienced in Dutch tax disputes can assess the authority’s allegations, examine the evidence and help determine how to respond if a VAT assessment, penalty or criminal concern is involved. That role is not necessarily a substitute for the company’s accountant or tax adviser; it becomes particularly valuable when the dispute turns on legal standards, procedural safeguards or litigation strategy.

Early advice can also help a business avoid two costly extremes: dismissing a serious enquiry as routine paperwork, or reacting as though an allegation has already been proved.

Build a business that can explain its decisions

No due-diligence process removes every risk from cross-border trade. What a good process does is preserve the reasoning behind important decisions: who was checked, what was agreed, why the deal made sense and how concerns were handled. If a VAT dispute arises later, that contemporaneous account may matter far more than a perfect-looking file assembled after the fact.
