An audit questioned governance of the ATO's AI models for expense claims

Problem

The Australian Taxation Office needed to identify potentially non-compliant work-related expense claims for human review.

Approach

The ATO's data science team developed AI models to support human decisions about expense claims. Its substantiation risk model was first deployed in August 2021. A federal audit questioned model design and explainability, and found that the ATO lacked a framework of policies and procedures for AI model development.

Results

No published figures

Takeaway

The models were already supporting reviews while the ATO developed broader AI governance. Enterprise-wide performance monitoring remained a future commitment.
