Guide to the money laundering offence in Spain in 2026
Area: Economic criminal law
Reader: companies, obliged entities, directors and individuals under investigation
Sources reviewed: Criminal Code, Law 10/2010, SEPBLAC and the BOE
Money laundering is one of the economic offences that has grown most in practical relevance in recent years, both because of the tightening of prevention rules and the rise in criminal investigations affecting companies, professionals and individuals who, in many cases, were not aware of the risk they were taking on. It is no longer an offence that affects only criminal organisations: financial institutions, notaries, real estate agencies, tax advisors and companies of every size can be flagged if they fail to meet their monitoring obligations, and anyone can be investigated if they handle funds whose origin they cannot justify.
This guide explains what money laundering is, how Spanish law regulates it, which specific conduct constitutes an offence and what penalties apply, what prevention obligations fall on so-called obliged entities, how it differs from other related economic offences, and which mistakes tend to trigger a criminal investigation into a company. The aim is to provide a clear framework for understanding the risk, spotting it in time and knowing what steps to take if it has already materialised.
It is worth noting from the outset that money laundering is a particularly sensitive matter from an evidentiary standpoint. Unlike other economic offences, it does not require proving precisely which specific offence the funds came from; it is enough to establish reasonable indications of an unlawful origin. This particularity considerably widens the scope of the offence and explains why apparently routine transactions — an international transfer, a large cash payment, a purchase with unclear financing — can end up triggering an investigation if there is no reasonable economic justification behind them.
A second factor adds to this: prevention rules impose active obligations, not merely passive ones. It is not enough not to take part in laundering; obliged entities must monitor, identify and, where appropriate, report. Failure to meet these obligations can lead to administrative sanctions independent of any criminal liability, and even to the commission of the offence itself through gross negligence when the lack of diligence is especially flagrant. Understanding this dual dimension — criminal and preventive — is the first step to managing the risk properly.
What money laundering is and how it is regulated
Money laundering consists of giving an appearance of legality to assets or money derived from criminal activity, integrating them into the legal economic system as if they had a lawful origin. The process is usually described in three stages: placement, in which the illicit funds first enter the financial or economic system (for example, through structured deposits or asset purchases); layering, in which successive transactions — transfers, shell companies, cross-investments — are carried out to obscure the trail of the origin; and integration, in which the now “clean” funds are reincorporated into the legal economy as investments, businesses or apparently normal assets.
From a criminal-law standpoint, the conduct is defined in article 301 of the Criminal Code, which punishes anyone who acquires, possesses, uses, converts or transfers assets knowing that they derive from criminal activity, with the aim of concealing or covering up their unlawful origin, as well as anyone who helps a person who has taken part in the offence to evade the legal consequences of their acts. It is important to note that the predicate offence does not necessarily have to be a specific, proven serious crime: case law has firmly established that reasonable indications that the assets derive from criminal activity are sufficient, with no need for a prior conviction for the underlying offence.
From a preventive standpoint, the key piece of legislation is Law 10/2010, on the prevention of money laundering and terrorist financing, which transposes the relevant EU directives into Spanish law and sets out the list of obliged entities, their customer due diligence obligations and the sanctioning regime applicable in the event of non-compliance. This law is complemented by its implementing regulations and by the guides and instructions periodically published by the supervisory body. GraciaCalbet’s criminal law team regularly works across both dimensions — criminal and preventive — which you can review in more detail on the criminal law services page.
Conduct that constitutes an offence and applicable penalties
The money laundering offence covers several forms, with different levels of severity depending on the degree of intent and the circumstances involved. Wilful conduct — that is, when the perpetrator positively knows that the assets derive from criminal activity and acts to conceal it — is punished with imprisonment of six months to six years and a fine of one to three times the value of the assets. In many cases, additional penalties are added to this main sentence, such as special disqualification from practising the profession or industry for a set period.
There is also a gross negligence form, designed precisely for cases in which a professional or a company, through a lack of the minimum required diligence, fails to detect or prevent its services or structures being used to launder funds. This form carries lower penalties than the wilful one, but it is especially relevant for obliged entities — financial institutions, advisors, real estate agencies — because it does not require intent to launder, only serious negligence in controlling transactions.
The Criminal Code also sets out several aggravated forms that substantially increase the penalty. It is aggravated, among other cases, when the assets derive from offences related to drug trafficking, terrorism, corruption or organised crime; when the perpetrator belongs to a criminal organisation or group dedicated to these activities; or when the offender is a professional habitually engaged in money laundering, as occurs with certain financial managers or intermediaries. In these cases, prison sentences can well exceed six years and fines increase proportionally.
| Form | Indicative penalty | Key point |
|---|---|---|
| Wilful | Prison of 6 months to 6 years + fine | Knowledge of the unlawful origin and intent to conceal it. |
| Gross negligence | Lower penalties than the wilful form | Lack of the minimum required diligence, without intent to launder. |
| Aggravated forms | Prison over 6 years + increased fine | Drugs, terrorism, corruption, organised crime or habitual professional activity. |
| Legal entity | Fine, dissolution, suspension or judicial intervention | Offence committed for the company’s benefit without proper controls. |
The criminal liability of legal entities must also be taken into account: when the offence is committed within a company, for its benefit and by its representatives or employees without proper controls, the company itself can be convicted and face fines, dissolution, suspension of activities or judicial intervention, regardless of the individual liability of the people involved. This is where a well-designed criminal compliance programme, aimed at preventing and detecting these kinds of risks, can make the difference between an exemption from liability and a conviction for the company.
Prevention obligations for companies (obliged entities)
Law 10/2010 does not only define offences for those who launder money; it also imposes a set of active duties on certain professionals and entities, known as obliged entities. This list includes, among others, financial and credit institutions, notaries and land and commercial registrars, lawyers and tax advisors when they take part in certain transactions (buying or selling real estate or companies, managing funds, bank accounts or securities, setting up companies), real estate agencies and developers, casinos and gambling operators, and other professionals who manage third-party assets.
Prevention obligations are built mainly around customer due diligence: formally identifying the client and, where applicable, the beneficial owner of the transaction through reliable documents; understanding the purpose and nature of the business relationship being established; and applying ongoing monitoring of transactions to verify that they are consistent with the client’s declared activity. When the risk is higher — clients from high-risk countries, politically exposed persons, opaque corporate structures — the law requires enhanced due diligence measures.
On top of this comes the duty of special examination of transactions that, due to their amount, complexity or lack of apparent economic or lawful justification, appear unusual, and the ultimate duty to report suspicious transactions to the supervisory body. In Spain, this role falls to SEPBLAC, the Executive Service of the Commission for the Prevention of Money Laundering, which acts as the financial intelligence unit receiving reports from obliged entities, in addition to carrying out supervisory and inspection functions. Failure to meet these duties can lead to very high administrative sanctions, regardless of whether criminal liability is ultimately established.
A word of caution: by their nature, these obligations are not met on an ad hoc basis but through stable internal policies and procedures: prevention manuals, regular staff training, the appointment of a representative before SEPBLAC and, at larger or higher-risk companies, integrating these controls within a broader compliance programme.
Difference between money laundering and other related economic offences
Money laundering is often confused with other economic criminal law figures that share certain elements but have a distinct legal nature. This distinction matters because both the legal classification of the facts and the defence or compliance strategy to apply depend on it.
Handling stolen goods, regulated under article 298 of the Criminal Code, consists of acquiring, receiving or concealing assets derived from an offence against property or the socio-economic order with knowledge of their origin, but for the purpose of benefiting from them, with no need to give them an appearance of legality. Money laundering, by contrast, requires precisely that extra element: the intent to conceal or cover up the unlawful origin and integrate it into the legal system. In other words, someone who simply buys an item cheaply knowing it is stolen commits handling of stolen goods; someone who designs a chain of transactions so that the same asset, or its value, appears to derive from a lawful activity commits money laundering.
The tax offence, for its part, consists of the non-payment or evasion of taxes, and does not require the funds involved to derive from prior criminal activity: they may be perfectly lawful income that is simply not declared or is concealed from the tax authorities. In practice, however, the two offences can overlap: the evaded tax amount can itself become the subject of laundering operations if mechanisms are put in place to give an appearance of legality to that undeclared money, which requires a careful case-by-case analysis to determine which offences actually apply.
This distinction, while seemingly theoretical, has very concrete practical consequences for the conduct of proceedings, applicable limitation periods and available defence strategies, which is why it is advisable to obtain specialist advice as soon as a risk is identified or a notification related to any of these offences is received.
Common mistakes that create criminal risk for a company
Most money laundering proceedings that affect companies do not stem from a deliberate intent to commit a crime, but from an accumulation of organisational oversights that, over time, create real criminal risk. These are the failures that most often lead to an investigation:
Organisational mistakes that open the door to an investigation
- Not implementing due diligence protocols with clients and suppliers: operating without verifying the identity of the beneficial owner, without knowing the origin of funds or without documenting the purpose of the business relationship.
- Accepting cash payments above the legal limits without requiring or keeping the corresponding economic justification, providing a ready channel for placing funds of unlawful origin.
- Not training staff to detect suspicious transactions, leaving those in direct contact with clients and transactions without any criteria to work from.
- Ignoring warning signs in complex international transactions with no apparent economic substance: corporate structures across several jurisdictions, intermediaries with no clear function, or flows that do not match the declared activity.
It is precisely the employees in direct contact with clients and transactions who need to know how to spot warning signs — inconsistencies between the client’s profile and the transaction, unjustified urgency, reluctance to provide documentation — and the absence of regular training turns that first line of defence into a blind spot. Spotting these patterns in time, before the transaction goes through, is the difference between managing a risk and facing criminal proceedings.

Frequently Asked Questions (FAQs)
What is the difference between the money laundering offence and simply holding money of unknown origin?+
Holding funds whose origin cannot be justified does not by itself constitute the offence, but it can create indications that trigger an investigation. The money laundering offence requires proving that the person knew, or should have known with the diligence required, that the assets derived from criminal activity, and that they acted to give them an appearance of legality. In practice, the absence of documentary justification for the origin of assets is often the starting point of an investigation, which is why keeping proof of the lawful origin of funds is the best protection against this risk.
Does the predicate offence need to be proven to secure a money laundering conviction?+
No. Spanish case law has firmly established that it is not necessary to prove precisely which specific predicate offence was involved, nor that there is a prior conviction for it. Sufficient reasonable indications that the assets derive from criminal activity are enough. This particularity considerably widens the scope of the offence and explains why complex economic transactions with no apparent justification can give rise to a money laundering investigation even when the offence the funds derive from has not been identified or prosecuted.
Is there a minimum amount for a transaction to count as money laundering?+
The Criminal Code does not set a specific minimum amount for the money laundering offence: what matters is the conduct — giving an appearance of legality to assets of criminal origin — not the specific sum, although the amount does influence the severity of the penalty and the likelihood the transaction will be detected. The preventive sphere is different, where regulatory thresholds do exist (for example, regarding transaction reporting or cash payment limits) that trigger specific obligations for obliged entities, regardless of whether the transaction is ultimately classified as criminal.
Which companies are required to comply with Law 10/2010 on money laundering prevention?+
Law 10/2010 requires compliance from a broad list of entities and professionals known as obliged entities: financial and credit institutions, notaries and registrars, lawyers and tax advisors when they take part in certain asset or corporate transactions, real estate agencies and developers, casinos and gambling operators, among others. These entities must apply due diligence measures with their clients, examine unusual transactions and report suspicious ones to SEPBLAC, as well as maintain internal procedures and specific training for their staff.
What happens if a company fails to report a suspicious transaction to SEPBLAC?+
Failure to comply with the reporting duty can lead to very high administrative sanctions, independent of any criminal liability, and even to sanctioning proceedings against the entity’s own representatives. If it is also established that the failure to report stemmed from gross negligence that objectively facilitated the laundering of unlawful funds, the company and its officers could also face criminal liability under the negligent form of the offence, with the consequences that entails for both the individual and the legal entity.
Can an individual be investigated for money laundering without being an obliged entity?+
Yes. The prevention obligations under Law 10/2010 apply to obliged entities, but the money laundering offence under the Criminal Code can be committed by anyone, whether or not they are an obliged entity. An individual who acquires assets, invests or moves funds knowing that they derive from criminal activity, or with reasonable indications sufficient to suspect it, can equally be investigated and convicted, regardless of their profession or usual economic activity.
What should I do if I receive a notification or summons related to a money laundering investigation?+
The first thing is not to make any statements or provide documentation without prior legal advice, since any action taken at this stage can shape the rest of the proceedings. It is advisable to gather all documentation that proves the lawful origin of the funds or assets in question and to contact a firm specialised in economic criminal law immediately, to assess the specific procedural situation, define the most suitable defence strategy and provide support to the person under investigation at every stage of the proceedings from the very first moment.
Can a company avoid criminal liability if it proves it had an adequate prevention programme?+
Yes, having an effective criminal compliance programme, tailored to the real risk of the activity, with due diligence protocols, staff training and active oversight channels, can be decisive in mitigating or even excluding the legal entity’s criminal liability if, despite those measures, an employee or director still engages in criminal conduct. The key is that the programme is genuinely implemented and kept up to date, not merely on paper, which is why it is worth reviewing periodically with specialist advice.
