Australia: No Mortgage Interest Deduction for Owner-Occupiers
Australia has no mortgage interest deduction for homeowners who live in their property. Unlike the United States, there is no equivalent of Schedule A interest deductibility for the Australian Tax Office (ATO).
The lack of a primary residence mortgage interest deduction is partially offset by the main residence CGT exemption — no capital gains tax on the sale of your principal place of residence.
Investment Properties: Negative Gearing
Mortgage interest on investment/rental properties is fully deductible against rental income. If the deductible expenses (including mortgage interest) exceed rental income, the net loss can typically be offset against other income — a strategy known as negative gearing.
Negative gearing is widely used in Australia: approximately 1.9 million Australians declare rental losses annually.
How Australia Compares
Among OECD countries, Australia (like Canada) stands out for lacking primary-residence mortgage interest relief. The US, Netherlands, Norway, Denmark, and Switzerland all offer meaningful deductions. Australia's homeownership rate (~67%) is higher than Germany's despite no deduction — driven by cultural factors and the CGT exemption.
