Federal Parliament has closed an unintended loophole in the recent negative gearing and capital gains tax reforms that became widely known as the “widow tax”. At the same time, the Government also fixed a technical issue that could have affected people who first use a main residence to generate rental income after Budget night on 12 May 2026.

What the problem was

As you might be aware, the tax rules have recently been changed to ensure that losses generated from residential rental properties from 1 July 2027 can be ‘quarantined’. This means that they can only be offset against income or capital gains generated from other residential rental properties. However, the changes won’t generally apply to properties that were purchased by the relevant taxpayer before 12 May 2026.

However, a problem could arise when an ownership interest in a property passes to someone as a result of the death of the original owner or because of a relationship breakdown and this occurs after 12 May 2026. Under the original version of the new rules, that transfer could be treated as a new acquisition. This could have meant that a surviving spouse or former partner risked losing the protected negative gearing treatment that had applied to the property in the hands of the previous owner.

How it was fixed

The Government moved quickly once the issue was identified. Some new rules now specifically protect people who acquire a residential property interest from a spouse because of death or relationship breakdown. The rules can also potentially protect someone who inherits an additional ownership interest in a rental property from a co-owner who isn’t their spouse.

Case study 1 – the widow tax fix

Sarah and David bought a rental unit in 2019 as equal joint owners. The property has always been negatively geared, with annual rental losses of around $8,000 offset against their other income each year.

Under the original May 2026 reforms, the property was protected because it was acquired well before Budget night. However, if David had died and the property transferred fully into Sarah’s name, the additional 50% interest that Sarah inherited from David’s estate risked being treated as a new acquisition. Sarah could have lost the ability to claim the losses generated from this interest in the property against her other income.

With the updated rules now in place, that outcome is avoided. Because the transfer occurs due to the death of a spouse, Sarah keeps the original protected treatment and can continue offsetting the rental losses in the same way as before.

Former main residences

A related technical issue also needed fixing. Under the original rules there was a risk that an existing main residence purchased before 12 May 2026 could lose its protected status if it was later first used to generate taxable rental income after that date. This was because of the interaction with a long-standing tax rule that can treat someone as if they had reacquired a former main residence when it is first used to produce income.

The Government has now passed legislation to correct this. The new rules specifically disregard that “first use to produce income” rule when determining the acquisition date for negative gearing purposes.

Case study 2 – renting out a former home

James bought his home in 2018 and has lived in it as his main residence ever since. In 2027 he decides to move in with his partner and rent the property out for the first time.

Under the original drafting of the 2026 reforms, first renting the property after 12 May 2026 risked resetting its acquisition date. That could have caused the property to be treated as a post-Budget night acquisition and subjected to the tighter negative gearing limits.

With the new rules now in place, that reset is disregarded for negative gearing purposes. Because James originally acquired the property before 7:30 pm on 12 May 2026, it keeps its original acquisition date. He can continue to offset any rental losses in the same way as if the property had always been an investment property acquired before Budget night.

Why these fixes matter

Both changes remove sources of unexpected cash-flow disruption. The “widow tax” fix protects people at a difficult personal time. The main residence clarification gives homeowners greater flexibility if their circumstances change and they later decide to rent out a property they already own.

What you should do now

• If you own a jointly held investment property acquired before 12 May 2026, the “widow tax” fix provides reassurance that a future transfer on death or separation should not remove negative gearing rights, but the rules are still complex and it is always best to have the position checked.
• If you own a main residence bought before 12 May 2026 and are considering renting it out in future, the new rule means the property should keep its original acquisition date for negative gearing purposes, but there could still be some complex CGT implications.
• Keep clear records of the original purchase date and ownership history.
