Frequently Asked Questions
When is stamp duty paid in Australia?
Stamp duty is due at settlement — the day legal ownership transfers. Your conveyancer calculates and arranges payment. In most states you have 30 days from the contract date to pay, but payment typically occurs simultaneously with settlement. Budget for stamp duty as part of your upfront purchase costs.
Is stamp duty deductible for tax purposes?
Stamp duty on your primary residence is not income tax deductible. For investment properties, stamp duty on purchase forms part of the property's cost base, reducing your Capital Gains Tax (CGT) liability when you eventually sell. For commercial property purchases, stamp duty may be deductible — consult a tax professional.
Which Australian state has the lowest stamp duty?
This varies significantly by purchase price. For a $750,000 property, NSW tends to be among the lower, while VIC can be higher. At $1,000,000+, differences narrow. For first home buyers, the concession schemes matter as much as the base rates.
What is land tax and is it different from stamp duty?
Yes — they are completely different taxes. Stamp duty is a one-off transaction tax paid when you buy. Land tax is an annual tax levied by state governments on the unimproved value of land you own (excluding your principal place of residence in most states). Land tax applies primarily to investment properties and commercial land.
