Reporting an unusual transaction to FIU-the-Netherlands

By Mitchell Zandwijken · 4 September 2026 · FIU reporting, MLRO

Dutch law obliges you to report unusual transactions to FIU-the-Netherlands without delay — a lower threshold than the suspicion standard used in almost every other member state. You report what is unusual; FIU-the-Netherlands analyses it, decides what is suspicious and passes that on to law enforcement. You are not required to prove anything, and reporting in good faith carries a statutory indemnity. Foreign groups systematically under-report here because their policies are calibrated to a threshold Dutch law does not use.

The Dutch standard: unusual, not suspicious

If your group framework was written in another member state, your reporting trigger is almost certainly suspicion. An alert is investigated, an analyst forms a view, and when that view hardens into suspicion a suspicious transaction report is filed. The Netherlands does not work that way, and this is the single most consequential difference for a foreign firm operating here.

The Wwft obliges institutions to report unusual transactions. Unusual is a materially lower threshold than suspicious. It is reached when an objective indicator applies, or when you have grounds to suppose that a transaction may be connected to money laundering or terrorist financing. You do not decide whether a transaction is suspicious. That judgement belongs to FIU-the-Netherlands, which analyses the reports it receives and may declare a transaction suspicious, after which it becomes available to investigative and intelligence services.

	Unusual	Suspicious
Who decides	The institution	FIU-the-Netherlands
Threshold	An objective indicator applies, or there are grounds to suppose a link to money laundering or terrorist financing	Analysis by the FIU points to money laundering or terrorist financing
Evidence required	None. A supposition is enough	Not your assessment to make
Consequence	Report to FIU-the-Netherlands	Made available to investigative and intelligence services
Equivalent step elsewhere	In most suspicion-based regimes nothing is filed at this stage	Roughly the point at which an STR would be filed

The practical consequence: you do not have to demonstrate anything. Holding a case back until you are certain something is wrong is precisely what the Dutch system does not ask of you, and it is a classic supervisory finding. The two steps — unusual, then suspicious — are frequently collapsed into one by firms that import a group standard wholesale.

Who has to report

The Wwft makes a broad group of undertakings co-responsible for guarding the gate: banks and payment service providers, but also civil-law notaries, accountants, estate agents, trust offices, crypto service providers and dealers who accept large cash payments. If you provide a regulated service in or from the Netherlands, the obligation attaches to you directly, not to your parent.

That last point matters for groups. A Dutch branch, subsidiary or licensed entity reports to FIU-the-Netherlands under Dutch law. A report filed by an affiliate with its own national FIU does not discharge the Dutch obligation, and group escalation routes that end at an overseas MLRO tend to lengthen exactly the step Dutch law requires to be short. See our guide to AML/CFT in the Netherlands for how the wider obligations fit together.

Objective and subjective indicators

The reporting obligation runs along two tracks that exist alongside each other. Both are live at all times; satisfying one is enough.

	Objective indicator	Subjective indicator
Character	A hard rule — if it applies, you report	An open norm — it calls for professional judgement
Own assessment	No	Yes, and you record it
Examples	Certain cash transactions above a set limit; transactions involving designated high-risk countries	Transactions that do not fit the known profile; structures without an economic purpose; shifting explanations about the origin of funds
How it is missed in practice	Systems apply the limit incorrectly, or apply an out-of-date version of it	Nobody records the assessment, so it cannot be shown that one was made

The indicator list is established per category of institution and is revised periodically. So do not only check whether your systems apply the indicators; check whether they apply the current version. A rule set migrated from a group platform three years ago and never revisited is a common source of missed objective reports, and it is the kind of gap a supervisor can find quickly because it is testable against data.

On the subjective side, the material is the ordinary set of laundering signals — unexplained cash, structuring, round-trip flows, counterparties with no commercial logic. Our note on recognising money laundering sets those out. What is distinctive here is not the signal but the threshold at which it must leave your organisation.

Without delay, and what that means

The statute says the report must be made without delay once the unusual character of the transaction has become known. In practice that means within a few working days. Two situations account for most late reports:

The internal assessment takes too long. An alert that sits in a work queue for three weeks before anyone looks at it makes the report late by definition, even if the filing itself follows quickly once the case is picked up. The clock does not start when your analyst opens the case; it starts when the unusual character became known to the institution.
The firm waits for certainty. Further investigation is fine, but not as a reason to postpone the report. Additional information can be passed to the FIU after filing, and the FIU can ask you for more.

The obligation also covers intended transactions that were never executed — including the case where a client walks away as soon as you start asking questions. A client abandoning a transaction at the moment of enquiry is itself often the signal that calls for a report, rather than the reason the file can be closed.

Setting up the reporting process

Signal. From transaction monitoring, from the first line, or from open sources. Make sure staff have a route that does not depend on their own view of whether the matter is serious.
Assessment. An analyst tests the signal against the client profile and the indicators, and puts questions to the client where useful — within the limits of the tipping-off prohibition.
Decision. The MLRO or designated officer decides whether to report. Record both the decision to report and the decision not to report, with reasons.
Report. File with FIU-the-Netherlands through its reporting portal, with the information the FIU needs in order to analyse: the transaction, the client profile, and your own reasoning.
Follow-up. Revise the risk profile, assess whether the relationship can continue, and update the file.

Step three is what supervisors ask about. Files usually contain the reports that were made; they rarely contain the reasoning for the cases in which a deliberate decision was taken not to report. It is that record which shows there is a process rather than an accident. If your MLRO capacity is the constraint, an interim MLRO can carry the decision and the documentation while the permanent arrangement is settled.

What happens after you report

Once filed, the report leaves your control. FIU-the-Netherlands analyses it, may combine it with other reports and with data it holds, and may come back to you for further information. Where the analysis points to money laundering or terrorist financing, the FIU declares the transaction suspicious and makes it available to investigative and intelligence services. Anything beyond that is a matter for those authorities.

Three consequences that foreign firms regularly get wrong:

Silence is not clearance. You will not normally be told what happened to a report. The absence of feedback says nothing about the quality of your filing and is not a reason to raise your internal threshold.
Reporting does not settle the relationship question. Filing and deciding whether to continue serving the client are separate decisions, taken on separate grounds and recorded separately. A report is not an exit, and an exit is not a substitute for a report.
The file continues. Adjust the risk profile, consider whether related transactions or connected clients need reviewing, and expect that a client who generated one report may generate more. Keep the report and the supporting reasoning under the Wwft retention period of five years.

The tipping-off prohibition and the indemnity

Two provisions hold each other in balance, and together they point in one direction.

Tipping off. You may not inform the client or any third party about a report you have made or about an ongoing investigation. Breach is a criminal offence. You may terminate the business relationship, but frame the reason so that it does not in substance amount to tipping off — a candid explanation of why you are exiting can cross that line without anyone intending it to.
Indemnity. A firm that reports in good faith is not liable for damage flowing from the report. That protection exists precisely to keep the threshold for reporting low.

Read together, they produce an unambiguous direction of travel: reporting costs you nothing; not reporting does. Where a group legal function is anxious about client-confidentiality exposure or contractual claims, this is the point to put in front of it. The exposure the Dutch regime creates is on the side of silence, not on the side of filing.

Why firms under-report here

Under-reporting by foreign-owned institutions in the Netherlands is rarely a matter of bad faith. It is almost always structural, and the causes repeat:

The group threshold is imported unchanged. Policies, decision trees and quality-assurance criteria written for a suspicion standard filter out exactly the population Dutch law wants reported.
Reporting only after certainty. The threshold is a supposition, not proof. Analysts trained to build a case before filing will file late, or not at all.
Non-reporting decisions are not recorded. Without reasons on file it cannot be seen whether a judgement was made or whether nothing was done.
An out-of-date indicator list in the system. Objective indicators change; monitoring platforms do not follow automatically, and a group vendor configuration is rarely localised on its own. An effectiveness review of your monitoring tests per scenario what a rule set catches and what it misses.
Escalation routes that leave the country. Requiring group sign-off before a Dutch filing adds days or weeks to a step the law requires to be immediate, and moves the decision away from the person who holds the Dutch obligation.
Reports without context. A filing with no client profile and no explanation is considerably less useful to the FIU, and a thin report is not a discharged obligation in any meaningful sense.
No feedback into the profile. After a report the risk profile often stays exactly as it was, even though a reason to revise it has just arisen.

The remedy is not more analysis. It is a Dutch-specific decision rule, held by someone in the Netherlands, that says plainly: if an objective indicator applies, or if we have grounds to suppose, we file — and we write down why when we do not.

Frequently asked questions

When must I report an unusual transaction?

As soon as a transaction meets an objective indicator, or as soon as you have grounds to suppose that a transaction is connected to money laundering or terrorist financing. The report must be made without delay after the unusual character has become known. You do not have to prove anything: a supposition is enough, and assessing it is the task of FIU-the-Netherlands.

What is the difference between unusual and suspicious?

The Netherlands has a reporting obligation for unusual transactions, which is a lower threshold than in many other countries where a report is only filed on suspicion. You report the unusual; FIU-the-Netherlands analyses it and, where warranted, declares a transaction suspicious, after which it becomes available to investigative and intelligence services. That judgement is not yours to make.

What is the difference between objective and subjective indicators?

An objective indicator is a hard rule: if it applies, you report, without any assessment of your own. Examples include certain cash transactions above a set limit and transactions involving designated high-risk countries. A subjective indicator does call for judgement: you report when you have grounds to suppose that a transaction may be connected to money laundering or terrorist financing.

May I tell my client that I have filed a report?

No. A tipping-off prohibition applies: you may not inform the client or a third party about a report you have made or about an ongoing investigation. Breaching it is a criminal offence. You may end the business relationship, but take care that the reason you give does not in substance amount to tipping off.

Am I liable if I report and it turns out to be unwarranted?

No. The Wwft provides an indemnity: a firm that reports in good faith is not liable for damage arising from the report. That protection exists precisely to keep the threshold for reporting low. The risk you do run is failing to report when you had grounds to suppose.

How quickly must a report be made?

Without delay after the unusual character of the transaction has become known. In practice that means within a few working days. An internal assessment process that takes weeks does not meet the requirement, and it is a recurring finding in supervisory examinations.

Do I also have to report intended transactions?

Yes. The reporting obligation also covers intended transactions that were not executed. A client abandoning a transaction as soon as you begin asking questions is moreover often a signal in its own right that calls for a report.
