Costs, Duty and 2026 Rules

What selling and buying a home costs in each state: agent commission, transfer duty, first home concessions, foreign buyer rules and capital gains tax.

Selling a home in Australia usually costs the agent's commission plus GST, a marketing campaign, conveyancing and the cost of paying out your mortgage. Buying costs transfer (stamp) duty, which is set by each state and territory, plus conveyancing, inspections and registration fees. On top of that sit the tax rules: the main residence exemption from capital gains tax, the 15% foreign resident capital gains withholding that has applied to every sale since 1 January 2025 unless the seller has a clearance certificate, and the foreign buyer surcharges and ban on buying established homes.

Start with the overview of the cost of selling a house. It links to the guides on agent commission by state, stamp duty by state, first home buyer concessions, the Victorian off-the-plan concession, foreign buyer surcharges, the main residence exemption and foreign resident withholding.

Duty rates, thresholds and concessions change in state budgets, often on 1 July. We give the figures we checked against official sources as at October 2026 and name the source, but always confirm with your state revenue office before you sign a contract.
