Frequently Asked Questions
How is stamp duty calculated in Australia?
Stamp duty (transfer duty) is calculated using a sliding scale of rates applied to the property purchase price. Each state and territory has its own rates, thresholds, and concessions.
Do investors pay more stamp duty than owner-occupiers?
In some states, investors pay higher rates than owner-occupiers. Foreign investors pay an additional surcharge in most states, ranging from 7–8% of the purchase price.
Is stamp duty tax deductible for investment properties?
Stamp duty is not immediately deductible but forms part of your CGT cost base, reducing your capital gain when you sell the property.
