“Widow tax” fixed

What the problem was

The tax rules have recently been changed so that, from 1 July 2027, losses generated by residential rental properties can be quarantined. This means they can be offset only against income or capital gains generated from other residential rental properties. The changes will not generally apply to properties purchased by the relevant taxpayer before 12 May 2026.

A problem could arise when an ownership interest in a property passed to someone after 12 May 2026 because of the original owner’s death or a relationship breakdown. Under the original version of the new rules, that transfer could be treated as a new acquisition. A surviving spouse or former partner could therefore lose 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. New rules now specifically protect people who acquire a residential property interest from a spouse because of death or relationship breakdown. They may also protect someone who inherits an additional ownership interest in a rental property from a co-owner who is not 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 inherited from David’s estate risked being treated as a new acquisition. Sarah could have lost the ability to claim the losses generated by that interest against her other income.

Under the updated rules, 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, an existing main residence purchased before 12 May 2026 could have lost its protected status if it was first used to generate rental income after that date. This was caused by its 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.

Legislation has now corrected 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.

Under the new rules, 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 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. The rules are still complex, so it is best to have the position checked.
• If you own a main residence bought before 12 May 2026 and are considering renting it out, the new rule means it should keep its original acquisition date for negative gearing purposes, but there may still be complex CGT implications.
• Keep clear records of the original purchase date and ownership history.
