If you are accused of complicity in a failure to file a tax return, the issue is not merely establishing whether the return was omitted. You must understand what personal contribution is attributed to you and whether that contribution may have criminal relevance. For an advisor, in fact, preparing data, requesting documents, holding an electronic delegation, or remembering a deadline does not automatically equate to deciding not to file a tax return.
I want to help you distinguish professional error, taxpayer default, and the more serious hypothesis of conscious participation in the crime. We will see what conditions make the failure to file criminally relevant, why the advisor is normally external to the filing obligation, and what facts can strengthen or weaken a charge of complicity.
When Failure to File Becomes a Crime
Omission is not always a crime. Under Article 5 of Legislative Decree No. 74 of 2000, applicable on the reference date of this guide, the following elements must concur: the failure to submit a tax return relating to income taxes or VAT, the obligation to submit it, the purpose of tax evasion, and the exceeding of the statutory threshold. The threshold requires evaded tax exceeding 50,000 euros for each individual tax; the prescribed penalty is imprisonment from two to five years. The regulatory text can be consulted in Legislative Decree No. 74 of 2000 on Normattiva.
The 90 days have a precise effect. A return submitted within ninety days of the deadline is not considered omitted for the purposes of the criminal provision; the same applies, within the terms established by the rule, to a return that is unsigned or not drawn up on the prescribed form. This does not mean that the delay is devoid of tax or administrative consequences: it means, however, that simple tardiness within that period is not sufficient to configure the crime of failure to file.
The threshold is not indiscriminately aggregated. If different taxes are involved, exceeding the limit must be verified with regard to each of them, without automatically summing amounts referring to different tributes. The calculation of the evaded tax therefore also requires attention: a figure indicated in a report or in a tax dispute does not resolve every criminal profile on its own, because the tax, tax period, and prerequisites of the provision must be reconstructed.
The applicable law requires attention to dates. The consolidated act under Legislative Decree 173/2024 reorganizes the subject, but its application has been deferred to 1 January 2027. On 21 September 2026, Legislative Decree 74/2000 therefore remains applicable. The deferral is expressly stated in current Article 102 of the consolidated act: approval and application of the new numbering do not coincide.
Why the Advisor Is Not Automatically Liable
The crime is proper to the obligated subject. Failure to file is a proper omission crime: it is materially committed by whoever, according to tax regulations, had the duty to submit the tax return by the deadline. For a natural person, the obligation falls on the taxpayer; for companies and entities, it is necessary to identify who held the relevant position and possessed the necessary powers in the considered period.
The advisor may be an accomplice, not the principal offender. The Court of Cassation has clarified that a subject upon whom the filing obligation does not weigh cannot be held responsible for material complicity in the omission conduct; complicity can instead be hypothesized on a moral level, when the external party instigates the author or reinforces their criminal intent. The principle is recalled in the penal review of the Court of Cassation, ruling No. 1465 deposited on January 12, 2024.
A professional assignment does not prove complicity. The mandate for bookkeeping or electronic transmission demonstrates that the advisor performed certain activities, but does not prove by itself either the intent to evade or adherence to an omission choice. The distinction is important: a failure to deliver documents by the client, termination of the assignment, conflicting instructions, or the absence of necessary data can explain why filing did not take place, without automatically transforming the professional into an accomplice to the crime.
Conscious participation is required. The prosecution must link the advisor's conduct to the criminally relevant decision of the obligated subject. This connection cannot be reduced to generic knowledge of the taxpayer's financial difficulty or the fact that the professional knew the deadlines. Instead, significance is attached to a contribution that consciously supported the choice not to file the tax return and that is accompanied by awareness of the pursued evasion.
Facts That Distinguish a Suspicion from a Well-Founded Charge
Who decided and when matters. The advisor's position changes if they only had a technical assignment or if they participated in company decisions, gave instructions on non-transmission, or assumed a de facto role in managing obligations. Even in the presence of a delegation for electronic transmission, the technical power to send a file must be distinguished from the power to decide what to declare, with what data, and whether or not to file the return.
Communications can have concrete weight. Emails, messages, reminder letters, draft returns, assignment revocations, and communications regarding document retrieval can clarify whether the advisor invited the taxpayer to comply, whether they received instructions not to proceed, or whether there was active conduct supporting the omission. Their meaning depends on the context and date: a message subsequent to the deadline does not necessarily demonstrate that the advisor contributed to the decision matured beforehand.
Data availability is a decisive fact. Having complete accounting and all elements to process the tax return is not equivalent to having incomplete registers, undelivered documentation, or patently unreliable data. The technical impossibility of preparing a correct return does not justify a fraudulent choice, but it can affect the reconstruction of the advisor's role and the real possibility that they voluntarily favored the omission.
The threshold must be verified for the contested period. A tax audit concerning multiple tax years does not allow the total amount to be automatically transferred to each year. For each tax period, it is necessary to establish which return was due, who was obliged to submit it, and which evaded tax is contested. This check serves both to understand whether the base crime is configurable and to evaluate whether advisor complicity may exist.
What Is Not Enough, by Itself, to Attribute Criminal Liability
Negligence does not coincide with intent. An error in the deadline calendar, unclear communication, or disorderly management of the assignment may have professional or tax consequences, but do not automatically prove the will to contribute to tax evasion. In the crime of failure to file, the intentional component cannot be replaced by generic inattention or the idea that the advisor should have noticed the problem.
Mere presence in the office is not enough. A collaborator, employee, or external professional who receives documents or participates in meetings does not become an accomplice just for this. It is necessary to identify conduct linked to the omission choice and verify awareness of its meaning. The distinction also protects those who perform executive tasks without decision-making powers or knowledge of the evasive project.
Not even the missed transmission is always attributable to the advisor. It is necessary to verify who held operational credentials, whether the assignment was still valid, whether the client had authorized transmission, whether definitive data were available, and whether there are communications documenting requests for integration or reminders. These elements are not formalities: they can show that the advisor had reported the risk and that the final choice belonged to the taxpayer or legal representative.
Remedying the Omission and Facing the Charge
Filing the tax return within ninety days avoids the classification of criminal failure to file. If that term has already expired, tax regularization must be distinguished from criminal effects. It is incorrect to think that every late-filed return always eliminates the crime: the timing of submission, payment of the debt, and formal knowledge of checks or proceedings affect the matter differently.
A ground for non-punishment exists under strict conditions. For declaration crimes, including failure to file, the legislation provides for non-punishment if the tax debt, along with penalties and interest, is fully extinguished through active remorse or submission of the omitted return within the deadline of the return for the subsequent period, provided that the activity takes place prior to formal knowledge of accesses, inspections, verifications, assessments, or criminal proceedings. The requirements are set out in Article 13 of Legislative Decree 74/2000.
Payment does not automatically erase every issue. When the ground for non-punishment has not matured in its prerequisites and timing, payment may still have relevance in other passages of the affair, but it does not allow one to state in the abstract that the proceeding will close. For the advisor, moreover, the taxpayer's payment does not answer the central question by itself: it remains to be ascertained whether there was conscious participation in the crime.
It is useful to order essential facts immediately. To understand one's personal position, the following are generally needed: the engagement letter and any revocations, delegations, communications on deadlines, electronic receipts, available drafts, delivered documents, and the chronology of relations with the taxpayer or administrator. There is no need to construct artificial explanations: it is more important to precisely separate what the advisor did, what they were asked to do, and what was not within their power to decide.
Frequently Asked Questions
Can I be investigated just because I held the delegation for electronic transmission?
No, the delegation alone is not enough. It demonstrates that you could perform a technical activity, not that you decided or consciously favored the omission. It becomes relevant to understand whether you had complete data, transmission authorization, effective powers, and communications showing a contribution to the choice not to file the return.
Does the advisor risk trial if the client does not deliver documents?
Failure to deliver can be decisive. If the client does not provide registers, invoices, or indispensable data and the advisor reports this, this element can exclude that the professional adhered to the omission choice. However, it does not eliminate the need to precisely reconstruct what was available and who decided not to comply.
Does the 50,000 euro threshold concern the total tax debt?
No, the check concerns the single tax. For the failure to file, the law requires that the evaded tax exceeds 50,000 euros with reference to each considered tax. It is therefore incorrect to automatically sum heterogeneous amounts or amounts referring to different tax periods to exceed the criminal threshold.
If the return is filed late, is the crime excluded?
Within ninety days, for criminal purposes it is not omitted. After that term, late submission does not automatically produce the same effect. Other rules may apply, including those on non-punishment linked to full payment, timeliness of regularization, and absence of formal knowledge of checks or proceedings.
Does payment of the tax debt also release the advisor accused of complicity?
Not automatically. Payment can affect the taxpayer's crime in the cases and times provided by law, but the advisor's position still requires verifying whether their conscious contribution exists. If complicity is missing, defense need not rely solely on the effects of payment; if complicity is contested, both profiles must be evaluated.
A Clarification Before Choosing How to Act
The charge must be read in its concrete formulation. It is essential to distinguish the taxpayer's tax obligation from the conduct attributed to the advisor, checking the tax period, threshold, documents, and chronology.
