TITLE: Australian Tax Reform: Tight Consultation Timelines and the Bills to Watch
Understand why industry groups are raising concerns
The Corporate Tax Association and 26 other industry associations have written jointly to the Federal Government about consultation on tax law and policy design. The alliance represents around 30 organisations, including COSBOA, the Australian Banking Association, the Business Council of Australia, the Insurance Council of Australia and the Australian Institute of Company Directors.
The groups say compressed consultation periods make it difficult for businesses and professionals to understand complex draft legislation, assess its practical effects and provide meaningful responses. They point to a 12-business-day window for consultation on the proposed minimum tax on discretionary trusts, among other short timeframes. By contrast, government guidance points to 30–60 days for significant reforms.
In its joint statement, COSBOA says rushed policy development can contribute to uncertainty, implementation challenges and unintended consequences. The Australian Banking Association’s account of the alliance letter outlines three requests: stronger Cabinet scrutiny of new regulation, an independent Office of Impact Analysis Commissioner, and standard minimum consultation periods across Commonwealth policy initiatives.
For your business, the concern is practical. When a proposal changes after a short consultation, you may have less time to understand the final rules and prepare your systems, records and reporting processes.
Check which reforms are moving through Parliament
The House of Representatives sits from 26 to 29 October 2026. Two tax bills are scheduled for debate on 27 and 28 October:
- The Treasury Laws Amendment (Tax Reform No. 3) Bill 2026.
- The Income Tax Rates Amendment (Minimum Tax on Discretionary Trusts) Bill 2026.
Together, the bills propose a 30% minimum tax on certain discretionary trusts, related roll-over relief and an electable regime. The package also includes capital gains tax (CGT) and negative gearing changes. These are proposals, not current law. The bills were referred to the Senate Economics Legislation Committee on 15 October, with its report due by 13 November 2026.
Separately, on 23 October, the Treasurer said the next tranche of tax reform legislation would be introduced this week, including start-up CGT concessions, changes to the Research and Development Tax Incentive and new venture capital incentives, as reported in Deloitte’s weekly tax round-up.
Use this week’s dates to stay ahead
Senate Supplementary Budget Estimates are also taking place during the sitting period. On 28 October, the Department of the Treasury Revenue, Small Business and Law Group is scheduled from 3.20 to 4.10pm. The Australian Taxation Office (ATO) is scheduled from 5.10 to 6.00pm, followed by the Tax Practitioners Board from 7.00 to 7.50pm.
These appearances give senators an opportunity to question officials about administration and implementation. Check the Senate Economics estimates program for the latest timetable.
Follow five steps while the rules remain proposals
-
Know which bills are before Parliament. Read the proposals on discretionary trusts, CGT and negative gearing so you can identify whether your company, trust or investment structure may be affected.
-
Diarise the key dates. Record the House debates on 27–28 October, the Senate committee report due on 13 November, and the ATO and Tax Practitioners Board appearances on 28 October. This helps you follow developments instead of relying on outdated summaries.
-
Review your trust and asset records now. Check your current structure, ownership information and relevant documents while existing rules and concessions remain in force. This gives you a clearer baseline for assessing any final changes.
-
Do not assume draft rules are final. Watch for amendments during House debate and the Senate inquiry. Waiting for the legislation’s progress can help you avoid changing processes in response to rules that may be revised.
-
Get professional advice before transacting. If you are considering selling, transferring or restructuring assets that could be affected by the CGT overhaul from 1 July 2027, seek advice before acting. The treatment may depend on the final legislation and your circumstances.
Don’t worry if the proposals feel difficult to interpret. Start by keeping reliable records and tracking official parliamentary updates. For background on a separate current trust compliance issue, see our Australia tax update on ATO interest relief for family trust tax liabilities.
