The challenge

Income-tax and sales-tax records contain different signals of potential non-compliance. Those signals need to be reconciled, evaluated and made useful to the officers choosing cases for further scrutiny.

The assignment brought rule-based analysis and machine-learning approaches into a common decision workflow. Technical work translated tax-domain questions into risk use cases, supported validation with domain officers and addressed how the system would be used by technical teams and field formations. Training and engagement with PRAL formed part of the delivery.
