A tax audit on the way: how to prepare and how to defend yourself.
A questionnaire from the Agenzia delle Entrate (Italian Revenue Agency), an invitation to the contraddittorio (the adversarial procedure with the tax office), an audit at your premises: these are manageable moments, if they are tackled methodically and without improvising. This guide explains what to expect and what to do, step by step.
The three channels of tax control
Automated and formal checks: cross-matching of the data you declared, arriving as communications or avvisi bonari (informal settlement notices), often settleable with reduced penalties. Questionnaires and invitations: requests for documents and explanations on specific transactions. Access and audits: the inspection carried out at your premises, which closes with the processo verbale di constatazione (the audit findings report, PVC).
What to do straight away
Read carefully what is being asked and by when: the deadlines are the first thing to keep under control. Involve your professional adviser immediately and reply in a complete but relevant way: you hand over what has been requested, ordered and explained — not your entire archive.
YOUR RIGHTS The Statuto del contribuente (the Italian Taxpayer’s Charter) lays down precise rules: the inspectors’ stay at your premises is limited in duration, you are entitled to be assisted by your professional adviser and, after the PVC, you have 60 days to submit observations before the assessment. The contraddittorio preventivo (prior adversarial procedure) is now the rule: use it, it is often where the position gets settled.
Documents in order, half the job done
Consistent VAT registers and VAT settlements, invoices and takings aligned with the electronic filings, contracts and supporting documents for the main transactions, reconciled bank statements. The quality of the documentation sets the tone of the whole audit.
IF THERE IS SOMETHING TO PUT RIGHT The sooner the position is regularised, the less it costs: the ravvedimento operoso (voluntary settlement) reduces the penalties significantly for as long as the breach has not been formally challenged. On this site you will find the calculator for a first estimate.
THE MOST COMMON MISTAKES Ignoring the communications in the hope that they will go away; replying in a hurry without a strategy; handing over more than was asked for; signing the audit records without having your own observations entered in them.

Tax audits: how to prepare and defend yourself
The three channels of tax control, your rights in the contraddittorio and the mistakes that cost dearly
Not all checks are the same
Receiving a communication from the tax authorities does not mean you are under audit. Understanding what kind of check it is, is the first step to reacting in the right way: without alarm, but without underestimating it either.
The three channels of tax control
1. Automated check
The Agenzia delle Entrate cross-matches the data in the returns with the payments made and with its own databases. This is where the avvisi bonari come from, flagging unpaid taxes or calculation errors. They are often resolved by paying or correcting, with reduced penalties if you act within the deadlines.
2. Formal check
Here the office asks you to produce the documents supporting the charges, tax credits and deductions shown in the return. Keeping and producing the evidence is essential: if the documentation is in order, the check closes without consequences.
3. Audit and access
This is the most far-reaching form of control: the Guardia di Finanza or the Agenzia delle Entrate enters the business or the office, examines the books and the documents and draws up a formal record. It may arise from reports, from anomalies in the indicators, or form part of the planned control programmes. An avviso di accertamento (notice of assessment) may follow from it.
What to do when an audit arrives
Ask for and check the authorisation for the access and the reasons stated in it.
Tell your commercialista (chartered accountant) straight away: you are entitled to be assisted.
Have your observations and requests entered in the record; every day of the audit is minuted.
Make the requested documents available, without handing over more than is due.
Keep a cooperative but prudent attitude: what you state stays on the file.
The Statuto del contribuente sets limits on how long the inspectors may stay at the premises: as a rule no more than fifteen working days within a quarter, save for reasoned extensions.
Your rights in the contraddittorio
Since 2024 the contraddittorio preventivo has been generalised: before issuing most tax assessment documents, the administration must send you a draft of the measure and allow you a period in which to submit observations. It is a concrete safeguard: used well, it can avoid the assessment altogether or reduce its scope.
After the audit report has been handed over you have sixty days to submit written submissions and observations before the document is issued.
The document must state its reasons: it must explain the facts and the grounds of the claim.
You can always ask for annulment in autotutela (self-review by the tax office) where the error is plain.
The tools for closing the matter
If a claim is well founded, in whole or in part, the law offers ways of settling the position while reducing the penalties.
Tool
In brief
Ravvedimento operoso (voluntary settlement)
Voluntary correction before the check, with heavily reduced penalties
Accertamento con adesione (settlement by agreement)
Agreement with the tax office, reduced penalties and payment by instalments
Acquiescenza (acceptance of the assessment)
Acceptance of the document with a reduction of the penalties
Conciliazione (settlement during litigation)
Agreement reached once litigation has begun
Autotutela (self-review by the tax office)
Annulment of a defective or incorrect document
The mistakes that cost dearly
Ignoring an avviso bonario and losing the reduction of the penalties.
Handing over documents or statements without the support of your professional adviser.
Letting the sixty days for observations, or the deadlines for the adesione, run out.
Not keeping the evidence of costs, tax credits and deductions for the required period.
Facing the audit on your own, underestimating the effects of what goes into the record.
The role of the firm
We stand beside you from the first contact with the administration through to the close: analysis of the document, conduct of the contraddittorio, choice of the most advantageous tool and, where needed, defence in litigation. Preparing in advance, with the accounts in order and the evidence preserved, is the best defence.
