5. GST Compliance Program

Learn the outcomes of the GST Compliance Program in 2024–25.

Last updated 12 December 2025

The GST Compliance Program contributes a significant proportion of the ATO’s GST administration results, returning approximately $22 billion in GST revenue to the states and territories since 2010.

The 2024–25 program results exceeded the GST liabilities commitment of $958.6 million with $2,158.5 million in liabilities raised. Actual 2024–25 GST debt collection of $1,748.6 million significantly exceeded the $263.6 million commitment.

In addition to increased liabilities and debt collection, the 2023–27 program includes measures to:

  • strengthen the GST registrations integrity, reducing the opportunity for GST fraud
  • increase the focus on intermediaries meeting their clients’ reporting obligations
  • support the delivery of next-generation GST risk models.

Program commitments are outlined in Schedule D – 2023–24 Budget Measure: GST Compliance Program – Four-year extension.
