How do tax audits work?
Tax audits on bank accounts in Italy are carried out directly by the Italian Revenue Agency, which does not require any judicial authorization to access bank data. Italian law provides that all banks and post offices annually provide the tax authorities with a detailed report of taxpayers’ financial relationships. This possibility is established by Article 32 of Presidential Decree 600/1973, which grants the Revenue Agency the necessary powers to conduct tax audits on bank accounts in Italy.
During these tax audits on bank accounts in Italy, the Agency verifies that bank transactions match what was declared in tax returns and analyzes any suspicious or unjustified operations.
What information is included in tax audits on bank accounts?
In tax audits on bank accounts in Italy, the Italian Revenue Agency can access:
- Account balance and bank transactions
- Transfers, credits, and debits
- Financial investments such as securities, bonds, and mutual funds
- Credit cards, debit cards, and prepaid cards
- Checks issued or cashed
- Existence of safe deposit boxes (without accessing the contents)
This information is available thanks to Article 51 of Presidential Decree 633/1972, which grants the tax authorities the right to investigate any financial relationship linked to the taxpayer.
Timelines and duration

The tax authorities can conduct tax audits on bank accounts in Italy up to five years after the submission of the tax return, if it was filed but is incomplete or contains omissions. For those who have never filed a return, tax audits on bank accounts in Italy can extend up to seven years.
Below is a summary table of the main terms related to tax audits on bank accounts in Italy:
| Term for tax audits on bank accounts in Italy | Taxpayer situation | Verification period | Starting point |
| 5 years | Return filed | Verification of bank transactions | January 1 of the year following the return |
| 7 years | Return not filed | Wider audits on accounts | January 1 of the year following the return deadline |
Methods of conducting
Tax audits on bank accounts in Italy are carried out with:
- Automatic audits, performed using software that compares bank data with tax returns. If discrepancies emerge, cases are flagged for further investigation.
- Targeted audits, in the presence of suspected evasion, involving specific investigations on bank accounts and requests for detailed information from banks, without the need for judicial authorizations.
Law no. 311/2004 expanded the powers of the Revenue Agency, allowing tax audits on bank accounts in Italy to extend to accounts held by third parties (family members, partners, directors) when there are connections with the investigated taxpayer.
The “anonimometro” and privacy in tax audits
To protect taxpayers’ privacy, tax audits on bank accounts in Italy use the anonimometro, an algorithm that analyzes data anonymously. Only when anomalies or inconsistencies are detected do in-depth audits proceed, avoiding unnecessary or excessive checks.
What happens if irregularities are found during tax audits on bank accounts?
If suspicious transactions emerge during tax audits on bank accounts in Italy, the Revenue Agency presumes that they derive from undeclared income. At this point, it is up to the taxpayer to prove the legitimacy of the transactions, for example with:
- Documents attesting already taxed income (winnings, prizes)
- Proof of exempt income (donations, compensations)
- Documentation of non-taxable transactions (repaid loans)
The presence of documents with a certified date is essential to avoid penalties or further assessments.
Extension of tax audits on bank accounts in Italy to third-party accounts
Tax audits on bank accounts in Italy may also concern accounts held by family members, partners, or directors if connections with the taxpayer are suspected. Italian jurisprudence has confirmed the legitimacy of this practice, especially in the presence of close family or corporate ties.
The right to defense
Every taxpayer subject to tax audits on bank accounts in Italy has the right to know in detail the reasons for the assessment and to provide all necessary justifications for each contested transaction.
Judgment no. 6407/2022 of the Court of Cassation emphasized that the taxpayer has the right to defend themselves and explain in detail every suspicious bank transaction.
