The Digital Client Registry is emerging as one of the most powerful tools available to the Independent Authority for Public Revenue (AADE) in its fight against tax evasion and the identification of high-risk businesses. According to the latest data released by the Authority, leveraging the system’s data has led to highly targeted audits, uncovering alarming violation rates — particularly across sectors linked to the automotive and transportation ecosystem.
AADE emphasizes that the Digital Client Registry is no longer simply a transaction-recording tool — it has evolved into a fully-fledged risk analysis instrument, enabling auditors to select which businesses to inspect with far greater precision. The data being leveraged covers businesses operating in vehicle repair and maintenance, car and spare parts trading, transportation, parking, car washing, vehicle painting, and other related activities.
Digital Client Registry: Audit results for 2025
According to figures presented by AADE, during 2025 a total of 949 targeted audits were carried out, based exclusively on data drawn from the Digital Client Registry.
Of these:
– 505 businesses were found to be in violation.
– The average violation rate reached 53.2%.
– A total of 5,882 violations were recorded.
In further detail, auditors identified:
– 1,095 violations for failure to transmit receipts.
– 1,026 violations for failure to issue or inaccurate issuance of receipts and invoices.
– 4 violations for failure to present tax documents.
– 3,753 other violations.
In addition, the total concealed value exceeded €100,000. AADE also moved to suspend the operation of several businesses, imposing temporary closures on wholesale and retail businesses as well as motor vehicle and motorcycle repair shops, while two land transport companies were also forced to suspend operations.
Even more violations recorded in the first half of 2026
Audit activity not only continued but was significantly stepped up from January 1, 2026, with AADE making even more effective use of Digital Client Registry data. In the first half of 2026 alone, 1,145 audits were conducted, of which 693 uncovered violations. The violation rate climbed to a striking 60.5% — a figure which, according to AADE, confirms the effectiveness of the targeted approach to selecting which businesses are audited.
The violations identified break down as follows:
– 2,552 violations in motor vehicle and motorcycle repair and maintenance.
– 3,474 violations in transport support activities.
– 91 violations in retail trade of vehicles and spare parts.
– 33 violations in wholesale trade of vehicles and spare parts.
– 81 violations in car rental businesses.
– 61 violations in land passenger transport.
A total of 6,292 violations were recorded, with fines imposed reaching €500,000. Enforcement authorities also moved to impose two-day closures on twelve businesses, applying the sanctions prescribed by law.
The data published by AADE clearly illustrates the significant contribution of the Digital Client Registry to targeted tax evasion enforcement. The ability to analyze available data allows audit mechanisms to identify high-risk businesses with greater accuracy, increasing the effectiveness of inspections and reducing the incidence of tax violations across these specific sectors.
