This internal budget review examines the ATO's Enterprise Solutions and Technology (EST) group spending for October 2024 to March 2025. The document is an operational record analyzing technology expenditure, which totaled nearly $1.3 billion (over 25% of total ATO budget) in the preceding financial year. EST received the highest funding allocation among five ATO groups. The review identifies that EST has received supplementary funding in recent years due to increased software costs, vendor pricing, contract expenses, and partially unfunded policy proposals. The report recommends addressing risks to budget sustainability by improving capacity to deliver flexible, innovative technology solutions within existing appropriations. It covers sustainment budget analysis across service towers (compute, storage, applications), outsourced IT labor, procurement practices, cyber considerations, and governance. The document reflects internal concerns about budget pressures and highlights recommendations for improved contract management and strategic sourcing to contain future costs.
