The so-called “widow tax” is not a new tax on widows or inheritances. It refers to an unintended consequence of the Government’s recent negative gearing and capital gains tax reforms.
In this article, Daniel Griffiths explains what the so-called ‘widow tax’ actually means, how the issue arose and what property owners should understand about the Government’s response.
Without correction, the issue could have affected the tax treatment of some residential investment property when ownership changes after a death or relationship breakdown.
The Government has moved to address the issue, with amendments now passed by Parliament on 19 August 2026.
How did the ‘widow tax’ issue arise?
The first stage of the Government’s negative gearing and CGT reforms has already become law. From 1 July 2027, negative gearing will generally be restricted to eligible new residential properties. Established investment properties acquired before 7:30pm AEST on 12 May 2026 are protected under grandfathering rules and can continue to be negatively geared under the existing arrangements.
The CGT rules are also changing. For gains accruing from 1 July 2027, the existing 50 per cent CGT discount will generally be replaced by cost-base indexation and a minimum tax rate of 30 per cent on capital gains. Transitional rules preserve the existing treatment for gains accrued before that date.
The unintended consequence emerged after this first stage of legislation passed.
Under existing tax rules, when one joint owner dies, the surviving owner may be treated as acquiring the deceased person’s interest at the time of death. A similar situation can arise when property is transferred following a relationship breakdown.
The problem was that without further amendment, this technical change in ownership could have caused some property interests to lose the tax treatment that would otherwise have continued. That is the issue the media has labelled the “widow tax”: not a deliberate policy, but a gap in the legislation that the Government has moved to address.
How has the Government addressed the issue?
The Government has moved to preserve qualifying tax treatment in these circumstances, with amendments now passed by Parliament. Broadly, the amendments are designed to allow an individual who acquires an interest in residential property following the death of a spouse or eligible co-owner, or as part of a relationship breakdown, to retain qualifying treatment that applied to the previous owner.
This includes preserving grandfathered negative-gearing treatment for qualifying established residential properties acquired before Budget night. The amendments also address the treatment of eligible new residential dwellings in relevant circumstances.
Other implementation measures relating to the broader CGT and negative gearing reforms remain subject to further legislative processes.
What does this mean for property owners?
For most people, the key point is this: Parliament has now passed amendments to remove the unintended consequence rather than introduce a new burden on surviving property owners.
The broader changes to negative gearing and CGT remain significant, and the core reforms are already legislated. Further implementation measures are still being developed, and the implications will vary depending on individual circumstances and broader financial objectives. LDB will continue to monitor developments as the reforms are implemented.
