Australia’s proposed reforms to the taxation of discretionary trusts remain one of the most closely watched elements of the Federal Government’s broader tax agenda, with employer organisations warning the changes could increase tax liabilities for hundreds of thousands of small and family-owned businesses.

The debate has intensified following renewed criticism from business groups, who argue the proposed reforms could affect investment decisions, business expansion and succession planning at a time when many enterprises are already dealing with rising operating costs.

Employer organisations including the Council of Small Business Organisations Australia (COSBOA) and the Australian Chamber of Commerce and Industry (ACCI) have warned that as many as 400,000 businesses operating through discretionary trust structures could face higher tax obligations under the proposed reforms. They argue trusts are widely used by family businesses, professional practices, farms and retailers for legitimate commercial reasons, including succession planning, asset protection and business continuity.

Under the government’s proposal, discretionary trusts would become subject to a minimum 30 per cent tax on trust income from 1 July 2028. Beneficiaries would generally receive tax credits for tax already paid by the trustee, although the final amount payable would depend on their individual tax circumstances. Existing trust structures would also be covered by the new rules, with restructuring relief proposed for eligible businesses.

Business groups argue that many small enterprises distribute income through trusts to family members involved in running the business, making the structure an established part of Australia’s small business sector rather than an aggressive tax planning arrangement. According to COSBOA, higher tax liabilities could reduce cash flow, limit investment capacity and make it more difficult for businesses to employ staff or expand operations.

The Albanese Government has defended the reforms, saying they are intended to improve fairness within Australia’s tax system by reducing differences between the taxation of discretionary trust income and wage income. Treasurer Jim Chalmers has stated that more than 90 per cent of Australian businesses are expected to be unaffected by the trust measures and has highlighted additional concessions introduced after consultation with industry.

Those concessions include expanded capital gains tax relief for eligible small businesses, rollover provisions allowing some businesses to restructure out of trust arrangements and several exemptions designed to reduce unintended consequences for genuine commercial operations. The Government says these measures demonstrate its intention to support business investment while modernising the tax system.

Tax specialists note that the practical impact of the reforms will depend on each business’s ownership structure, profitability and distribution arrangements. Some businesses may experience little change, while others with more complex trust structures could face significant adjustments before the proposed commencement date. Professional advisers have encouraged business owners to review existing arrangements well in advance should the legislation proceed.

The discussion also reflects broader questions about Australia’s future tax system. Supporters of reform argue that reducing differences between various forms of income taxation will improve equity and strengthen the long-term revenue base. Critics counter that additional tax complexity and higher effective tax rates may discourage entrepreneurship and investment, particularly among family-owned enterprises that form a substantial part of the Australian economy.

The proposed legislation has not yet completed the parliamentary process, meaning the final design of the reforms could still change following consultation and debate. Until then, Australia’s trust tax reforms are expected to remain a significant issue for policymakers, business organisations and tax professionals as they assess the balance between tax fairness and economic growth.
