GST Architect Defends System Amid Criticism of Inequity and Cost

Mathias Cormann, the former Western Australian senator who played a key role in designing the current goods and services tax (GST) distribution model, has pushed back against a new report that labels the system as both inefficient and unjust. In a robust defense, Cormann insisted that the framework is functioning precisely as intended, despite growing calls for reform.

The Productivity Commission's interim findings, released earlier this week, painted a stark picture of the existing arrangement, highlighting significant administrative expenses and a lack of fairness in how funds are allocated among states and territories. The report has reignited a long-running debate over the formula that determines each region's share of GST revenue, with several leaders demanding a complete overhaul.

However, Cormann, who now serves as the secretary-general of the Organisation for Economic Co-operation and Development (OECD), argued that the system's complexity is a necessary trade-off to ensure stability and predictability. He contended that the current mechanism, which includes horizontal fiscal equalization, was deliberately crafted to balance competing interests and avoid the pitfalls of ad-hoc decision-making.

Critics, including state treasurers from resource-rich regions, have long claimed that the system penalizes economic growth and discourages investment. They point to the disproportionate share of mining royalties that Western Australia contributes, only to receive a fraction back in GST payments. Yet, Cormann dismissed these grievances as shortsighted, insisting that the system rewards long-term fiscal prudence.

The Productivity Commission is expected to release its final report in early 2025, which will likely fuel further political wrangling. While Cormann's stance may not quell the chorus of discontent, his remarks carry weight given his central role in the system's inception. For now, the debate over how to fairly divide the GST pie remains as contentious as ever.
