Synopsis

A High Court battle over stamp duty on divorce-related property transfers is putting the states’ taxation powers under renewed scrutiny, with millions of dollars in exemptions at stake.

A long-running dispute over stamp duty on property transfers following divorce has put the tax powers of Australia’s states at the centre of a constitutional clash between Canberra and the jurisdictions.

The case challenges a legal position that has stood for about 45 years which is federal law cannot prevent states from imposing stamp duty on property transactions carried out by divorcing spouses.

In New South Wales alone, exemptions from the duty are estimated to be worth about $152 million a year, making the outcome financially significant for state governments.

Chapter one

A 1981 Ruling Back in Focus

The dispute traces back to the High Court’s 1981 decision in Gazzo v Comptroller of Stamps (Vic). The court considered whether the common wealth could use its constitutional powers over marriage and divorce to exempt property transfers made under Family Court orders from state stamp duty.

The majority found that the Commonwealth did not have the power to override state stamp-duty laws in those circumstances. The decision established a boundary between federal family law and the states’ taxation powers.

The issue has now returned to the High Court, with the Albanese government seeking to challenge the established position while other governments defend the states’ revenue-raising powers.

Chapter two

Millions at Stake for State Revenue

The dispute extends beyond divorcing couples. Stamp duty remains an important source of revenue for state and territory governments, particularly through property transactions.

For couples dividing assets after a marriage breakdown, however, the tax can add a significant cost to a process that is already financially disruptive. Exemptions currently available in some jurisdictions can reduce that burden.

The constitutional question is whether the Commonwealth can provide those protections through federal family law, or whether states retain the final say over taxes attached to property transfers.

The case could therefore have consequences well beyond divorce settlements. A ruling that expands Commonwealth power could alter the relationship between federal legislation and state taxation, while a decision upholding the existing position would reinforce the states’ authority over stamp duty.

For governments already navigating pressure to reform property taxes, the High Court’s decision could become an important marker in the broader debate over who controls Australia’s tax system.
