The allegation of unlawful tax consultancy can involve a professional, an intermediary or a company when the prosecution believes that a consultancy did not limit itself to interpreting tax rules, but contributed to the commission of an offense. If you are facing a report, an invitation, a search or a notice of investigation in Milan, the central question is not only which tax scheme was adopted: it is necessary to understand what specific act is attributed to each individual person.
I want to clarify three main points above all: when consultancy can take on criminal relevance, why the repetition of similar indications to multiple subjects is not enough on its own to prove an offense, and what elements distinguish questionable tax planning from a conscious contribution to evasion. We will also see what changes when invoices, tax returns, companies used as a screen, and relations with the tax authorities come into play.
Serial consultancy is not a standalone offense
"Unlawful serial consultancy" is a descriptive formula, not the name of a standalone crime. To support criminal liability, the prosecution must identify a specific tax offense and link the conduct of the investigated or accused person to that offense. Consultancy can therefore be examined in the context of fraudulent tax returns, the issuance of documents relating to non-existent transactions, undue offset or other tax offenses, but it is not sufficient to define it as "serial" to conclude that it is criminally relevant.
Contribution to the specific act matters. An opinion, an internal circular, a contractual model or an operational suggestion take on different relevance depending on whether they remained at an abstract level or were used to prepare returns, tax documents or operations not corresponding to reality. The defense must therefore distinguish general advice from participation in specific fraudulent conduct: who decided, who gave instructions, who produced the documents and who filed the return are different questions.
Repetition does not prove intent on its own. A procedure proposed to multiple companies may bring out an organizational issue and may attract the attention of investigators; however, to attribute an offense to a consultant, elements demonstrating awareness and the will to contribute to evasion or to obtaining an undue tax advantage are required. The exact same repeated solution may be lawful for some real operations and become problematic if adapted to false data, fictitious subjects or documents lacking an actual performance.
When the evasion scheme can aggravate the consultant's position
The increase in penalty requires cumulative conditions. The discipline currently gathered in Legislative Decree 74/2000 provides for a half-penalty increase when the offense is committed by an accomplice who carries out a tax consultancy activity as a professional, financial or banking intermediary, through the drafting or marketing of tax evasion schemes. The current reference is Article 13-bis, paragraph 3, of the Legislative Decree 74/2000.
Having a professional qualification is not enough. The circumstance concerns the accomplice in the offense: prior to the penalty increase, participation in the tax offense committed by others or together with others must therefore be demonstrated. The fact that a person is an accountant, consultant, administrative employee or intermediary does not automatically make them an accomplice. A concrete contribution to the commission of the offense and the necessary intentional element must be identified.
A scheme does not coincide with a single piece of advice. The expression refers to an operational structure prepared or proposed to carry out evasion, not every tax suggestion that the prosecution deems aggressive. Repeatable instructions accompanied by prepared documents, apparent corporate steps, invoicing flows not connected to real services or procedures aimed at bringing out costs, credits or subjects different from the actual ones can become relevant, for example. The decisive point always remains the nexus between the contested scheme and the single attributed offense.
Invoices, tax returns and apparent transactions: the distinctions that matter
The invoice is not just an accounting document. In tax offenses it can take on a central weight when used to represent a transaction that did not take place, took place only in part, was indicated for amounts different from the real ones or referred to a subject different from the one that actually performed the service. In these cases it is essential to separate the form of the document from the substance of the transaction: contract, activity performed, payments, communications and the supplier's capacity must be read together.
Issuing and using are different conducts. Those who issue documents intended to allow third parties to evade taxes may be held liable for issuance; those who use those documents in their own return may be involved for fraudulent return. The consultant, on the other hand, must not be automatically superimposed on either the issuer or the user. Their position depends on what they did and knew: materially preparing an act, knowingly suggesting a fictitious step or limiting themselves to receiving data presented by the client are hypotheses that require different assessments.
Economic reality comes before the label. An actually operating company can perform real services even if it belongs to the same group as other companies; an invoice can instead be contested if the indicated service finds no concrete feedback. For this reason it is not correct to base the response solely on the presence of corporate relationships, a high fee or the use of standardized contracts. It is necessary to understand what activity was carried out, by whom, with what resources, for what consideration and with what tax effects.
What must be proved regarding the professional and the company
The prosecution must individualize conducts. In proceedings involving multiple companies, directors and consultants, the risk is transforming professional proximity into criminal liability. A solid contestation must instead indicate the contribution attributed to each subject: a directive, a documentary choice, the drafting of a scheme, the role in the return or intervention in the circulation of invoices. Membership in a network of commercial relationships does not replace proof of complicity in the offense.
Communications can have a double meaning. Emails, messages, minutes, schedules and working notes can support the accusatory hypothesis or show that the consultant received incomplete information, reported risks or indicated a solution conditional on the reality of the data. However, a favorable document must not be read in isolation: its effectiveness depends on the date, recipients, language used and consistency with what happened afterward.
The company's position is distinct from that of natural persons. The tax assessment of the company, the liability of directors and the potential liability of the entity follow planes that may intersect but do not coincide. Even when the allegation concerns the same economic fact, shortcuts must be avoided: a tax adjustment does not automatically prove the criminal liability of all subjects involved, just as a criminal proceeding does not replace the verification of the tax claim.
Defensive choices and payment of the tax debt
Defense does not consist in denying everything indiscriminately. The first useful choice is to identify the core of the charge with precision: non-existence of the transaction, falsity of the indicated subject, evaded tax, the consultant's role, awareness of the fraud or connection between multiple companies. Contesting the wrong point can leave the decisive one unanswered. If, for example, the problem is the effectiveness of the service, the contract alone does not close the issue; if the problem is the consultant's role, it is necessary to clarify what contribution they had in the realization of the fact.
Payment does not wipe out every tax offense. For many fraudulent hypotheses, the extinction of the debt does not in itself constitute a ground for non-punishment. However, it can significantly affect the sentencing treatment. Article 13-bis of Legislative Decree 74/2000 provides, outside cases of non-punishment, for a reduction of the penalty by up to half and the non-application of certain accessory penalties when the tax debt, including penalties and interest, is paid before the closing of the first-instance trial.
Installment payment must be managed with precision. If the debt is being paid off through installments, the rule governs communication to the judge, the possible suspension of the trial and the effects of the regularity of payments. Lapsing from the plan changes the picture; furthermore, the suspension of the trial entails the suspension of the statute of limitations. The amendments introduced in 2024 on these aspects have merged into the currently applicable discipline; for facts prior to the regulatory reorganization, temporal rules and the most favorable discipline must be carefully applied when the prerequisites are met.
Plea bargaining and active repentance have their own requirements. For tax offenses, Legislative Decree 74/2000 links the request for the application of the penalty to the prior payment of the debt, including penalties and interest, or to active repentance in the cases provided for by law. It is neither an automatic choice nor a solution suited to every allegation: first, the consistency of the evidence, the legal classification of the fact, the patrimonial consequences and the position of the other people involved must be evaluated.
An orderly preparation avoids unnecessary misunderstandings. If you have to face a first defensive confrontation, it is useful to gather the received act, the affected returns, contracts, invoices, proofs of the activity carried out, payments and relevant communications. There is no need to produce random materials or approximate reconstructions: the chronological sequence of facts and the connection between document, transaction and return are often more important than the quantity of available files.
Frequently asked questions
Does incorrect tax consultancy always entail a crime?
No, an error does not automatically equate to a crime. Criminal liability requires a fact provided for by law as an offense and the necessary subjective elements. A questionable technical reading, an inaccurate calculation or advice that later turned out to be incorrect must be distinguished from conscious participation in a fraudulent return, fictitious documents or another tax offense.
Is the exact same procedure proposed to multiple clients already an evasion scheme?
No, repetition is not enough. A procedure can be standardized for organizational reasons and be lawful if applied to real and correctly represented operations. The aggravating circumstance instead requires an accomplice in the offense, the exercise of tax consultancy activity and the drafting or marketing of a scheme aimed at evasion.
Does the payment of the tax debt close the criminal proceeding?
Not necessarily. In fraudulent hypotheses, payment does not automatically eliminate liability. However, it can produce relevant consequences, including the reduction of the penalty by up to half and the exclusion of certain accessory penalties, under the conditions and terms provided for by Article 13-bis of Legislative Decree 74/2000.
Can I request plea bargaining if the debt is being paid in installments?
Installment payment does not coincide with the extinction of the debt. The discipline requires, for the request for the application of the penalty in tax offenses, the extinction of the debt before the opening of the trial, except for specific hypotheses provided for active repentance and grounds for non-punishment. It is therefore necessary to verify the actual status of payments and the procedural moment.
Does the tax assessment alone prove the consultant's liability?
No, the planes remain distinct. An assessment can provide important elements and can be acquired in the criminal trial, but it does not replace proof of the consultant's personal contribution to the offense. Concrete conduct, knowledge of false data and the connection with the contested tax fact must be clarified.
Useful regulatory references
In 2026, the reference is Article 13-bis of Legislative Decree 74/2000, as amended by the 2024 reform. The new consolidated act under Legislative Decree 173/2024 will apply from 1 January 2027 under Article 102. Its future numbering must not be applied prematurely; the date of the conduct and the rules governing successive criminal laws matter in every case.
An allegation of this type requires a punctual reading of the attributed conducts, tax documents and the moment in which each subject intervened.
