Government pressed on granny flat rule as budget changes rushed through

June 3, 2026 - 03:30

The federal government is facing mounting pressure to provide clear definitions around granny flat arrangements as it pushes major capital gains tax and negative gearing changes through parliament. While the core housing affordability reforms are being fast-tracked, detailed rules to cement the treatment of secondary dwellings into law are expected to come in separate legislation later.

Critics argue that without immediate clarity, families planning to build or occupy granny flats could face unintended tax consequences. The current rush leaves many homeowners uncertain whether rental income from a relative's unit will be treated as exempt or subject to the new, tighter rules. Industry groups warn that the ambiguity could stall construction of these smaller homes, which are often seen as a key solution for intergenerational living and housing supply.

The government insists that the subsequent legislation will provide the necessary legal framework, but opponents say the delay creates a dangerous gap. With the main bill already moving through both houses, stakeholders are calling for a pause or at least a transitional period. The outcome will affect thousands of Australians who rely on granny flats for affordable housing or to supplement retirement income.
