AI tax fraud detection
Institution: Ministry of Finance
What it is
Microsoft Anomaly Detector processes millions of electronic receipts to detect fake invoicing (EFOS) and inflated deductions (EDOS).
Verified results
₡8,000M (~USD 15.7M) recovered in 2025; 70+ fake-invoicing cases identified.
Context
The only Costa Rican state case with measurable, publicly reported fiscal returns in 2025. It rides on the consolidated v4.4 e-invoicing infrastructure; AI adds value on top of transactional data the State was already collecting.
