Ministry of Finance

Tax anomaly detection stack run by the Ministry of Finance combining three components operational in 2026: (1) Microsoft Anomaly Detector, in production since 2024 over the v4.4 e-invoicing receipt flow, identifying companies issuing fake invoices with no real operations (EFOS) and taxpayers artificially inflating deductions via third-party invoices (EDOS); (2) integration with TRIBU-CR, the tax platform operational since October 2025 that centralizes pre-filled returns and automated refund processing; (3) Atena, an AI module focused on the self-employed segment to monitor tax compliance over transactional data already captured by e-invoicing. The combined stack covers both general invoicing and the self-employed segment.

Virtual assistant integrated into the Ministry of Finance's Hacienda Digital platform, designed to guide taxpayers through key tax procedures: filing returns, processing payments, and managing foreign trade operations (imports and exports). Available to any taxpayer registered in the Costa Rican tax system, it operates as a self-service channel to reduce in-person and phone support demand. It is the only operational citizen-facing virtual assistant in the Costa Rican central government; no interaction volume metrics have been published.
