Italy’s tax authority assessed nearly €1 billion through audits selected with bank-data analysis over three years. Its 2026 report does not show how much of that amount was actually collected.
The checks produced 2,049 assessment notices for €108.5 million in 2023. In 2024, the number rose to 9,275 notices and €371.4 million in assessed tax. In 2025, the authority issued 15,873 notices for €513.7 million. The three-year total was 27,197 notices and €993.6 million in additional tax assessments. Another 3,578 taxpayers corrected their returns before an audit began.
The tax authority uses information from the Archive of Financial Relationships, which receives data from banks and other financial operators on account balances and average balances. It compares those records with information already held by the government to identify cases where a person’s or company’s financial position does not match declared income. The model is intended to filter out likely false positives.
For the first time, the report gives the number of checks and the amounts assessed, but it does not say how many cases ended in a settlement with the taxpayer or how much money was collected. The published figures therefore do not show how effectively the algorithm identifies actual violations.
Traditional financial investigations have produced limited collections, by comparison. According to the Court of Auditors, €14.9 million was collected in 2025 against €256 million assessed, or 5.8%. That figure is provisional. In 2024, collections were €5.1 million out of €248 million, about 2%. Those figures concern traditional investigations and do not measure the results of account-based risk selection.
