Buying in this price range

Above $2 million, stamp duty exceeds $100,000 in most states and can approach $150,000 or more. At this level, stamp duty is a transaction friction that discourages frequent buying and selling — sometimes referred to as a 'lock-in effect.' Some states apply premium rates or surcharges at higher price tiers. Professional property and tax advice is strongly recommended to optimise the structure of the purchase.

Structure of purchase matters

At $2 million+, consider whether the property should be held personally, in a trust, through a self-managed super fund (SMSF), or in a company. Each structure has different stamp duty, land tax, capital gains tax, and asset protection implications. Stamp duty applies regardless of structure, but the ongoing tax treatment differs significantly.

NSW premium foreign surcharge

In NSW, the Surcharge Purchaser Duty is 9% (from 1 January 2025). On a $2.5 million property, this adds $225,000 to the stamp duty bill — more than the standard duty itself. Combined with annual land tax surcharges, foreign ownership costs in premium brackets are substantial.

Typical buyers: High-net-worth individuals, downsizers from very high-value homes, developers, and international buyers investing in Australian premium property.
