A massive disparity has emerged in the wake of the federal government’s sweeping budget overhaul of property investment taxes, with official Australian Taxation Office data exposing a multi-billion-dollar loophole enjoyed almost exclusively by international buyers.
While domestic “rentvestors” and mum-and-pop property owners face tighter restrictions on negative gearing and capital gains concessions, ultra-wealthy offshore landlords have quietly accumulated $175 billion in property tax write-offs over the last decade.
The latest ATO financial year data reveals that in a single year, more than 34,000 non-resident landlords claimed net rental losses worth a combined $473 million. As reported by realestate.com.au, this is nearly four times the number of Australian residents who signed up as rentvestors in the exact same year.
Under current rules, these international property owners accumulate these massive losses year after year. When they eventually sell the asset, the billions in carried-forward deductions are weaponised to drastically slash their Australian Capital Gains Tax (CGT) liabilities.
The ‘wealthier you are, the less relevant the rules’
The complete immunity of international buyers from the recent budget crackdowns has drawn sharp criticism, with experts pointing out that the architectural flaws in the federal budget actively protect high-net-worth offshore buyers while penalising smaller-scale domestic investors.
John Storey, Tax Counsel at the Tax Institute, highlighted the blunt reality of how these recent budget changes unfairly target local buyers rather than international syndicates.
“The federal budget’s changes to capital gains tax benefits and negative gearing will have no impact on wealthy foreign investors, despite major changes for smaller-scale Australian investors,” Mr Storey said. “It is one of those budget changes where the wealthier you are, the less relevant the rules become.”
According to the ATO’s financial models, the scale of these tax savings is immense. An offshore investor who bought a house in Sydney and held it for a decade would look at a raw profit of $701,000, attracting a standard $295,650 tax bill.
However, by simply deploying $100,000 in accumulated net rental losses, they can legally slash their bill to $250,650, stripping $45,000 directly from the Australian taxpayer.
The decade-long breakdown of foreign claims includes $68.6 billion in mortgage interest deductions, $10.5 billion in capital works depreciation, and $65 billion in generalised “other” rental deductions.
The revelation has caused widespread frustration across the real estate sector, particularly for younger generations who are systematically being priced out of their own local capital city markets.
However, housing industry leaders argue that completely dismantling the foreign tax relief model could trigger a sudden collapse in Australia’s already struggling rental supply pipeline.
Property Investor Council of Australia (PICA) chair Ben Kingsley said that while the scale of the deductions may shock the public, the capital remains a critical piece of the broader housing puzzle.
He said Australia’s housing system is an ecosystem and it relies on foreign investment to help support the infrastructure and architecture of the system; without tax relief, foreign investors are less likely to invest in the market.
Mr Kingsley also added that a distinct positive in the data shows that international investors are actively renting their properties out to local residents rather than holding them as vacant wealth stores.
Data Summary: non-resident claims breakdown (past decade)
The following figures illustrate the specific categories where non-resident property owners have concentrated their $175 billion in Australian tax write-offs:
| Deduction Category | Ten-Year Total Claimed | Impact on Revenue |
| Rental Interest Deductions | $68.6 Billion | Slashes annual taxable income on mortgage interest. |
| Net Rental Losses | $35.0 Billion | Carried forward to offset future Capital Gains Tax upon sale. |
| Capital Works Depreciation | $10.5 Billion | Claims on building construction and structural wear. |
| Other Rental Deductions | $65.0 Billion | General operational, maintenance, and management fees. |
The formal residential data from the ATO Register of Foreign Ownership of Australian Assets outlines the exact geographic and demographic footprint of foreign-held addresses across the country.
The global leaderboard – properties actively held
Wealthy investors from mainland China and Hong Kong heavily dominate the active register.
- Mainland China: 23,550 properties
- Hong Kong (SAR): 3,486 properties
- Singapore: 1,978 properties
- Malaysia: 1,795 properties
- Japan: 1,711 properties
The target states
International buyers continue to target Australia’s two largest economic engines, completely undeterred by aggressive foreign stamp duty surcharges.
- Victoria: The absolute epicentre of offshore residential ownership, containing 16,929 addresses (over 40% of the entire national inventory).
- New South Wales: Ranks second with 8,862 addresses, even after increasing its foreign buyer stamp duty levy to a nation-leading 9%.
- Queensland: Holds 8,129 addresses, driven heavily by apartment volume in the state’s south-east.
Property profiles: Buying the pipeline
The register proves that strict foreign investment laws are steering international capital exactly where the government intends: directly into new builds rather than established family homes.
- New Construction Dwellings: 23,147 addresses.
- Established Dwellings: 8,463 addresses (highly restricted under a strict multi-year foreign buyer ban).
Crucially, the vast majority of these purchases (31,888 properties) were secured for under $1 million, meaning foreign capital is heavily concentrated in the exact price bands where local first-home buyers and high-density renters are actively competing.
