A rental property is said to be negatively geared if the owner’s expenses (including mortgage interest and maintenance) exceed the rental income, so that the property makes an annual loss. If the tax system allows negative gearing deductibility, that loss can be deducted from other income for tax purposes. Abolition of this deductibility, loosely known as “abolition of negative gearing”, would make the owner’s expenses deductible against the rent alone — not against other income.
SPIN: Negative gearing deductibility helps renters and first home buyers by encouraging property investors to “supply accommodation”; the larger the supply, the lower the rents and prices.
