Stamp duty is payable on settlement day — the day you take legal ownership of the property. Your conveyancer will calculate the exact amount and arrange payment as part of the settlement process. You need to have the funds available by settlement.
No — stamp duty cannot be added to your home loan. It must be paid upfront at settlement from your own funds. This is why stamp duty is a critical part of your upfront cost budget alongside your deposit.
For owner-occupiers, stamp duty is not tax deductible. For investment properties, stamp duty forms part of the cost base of the asset and may reduce capital gains tax when you sell, but it is not deductible in the year of purchase. Always confirm with your accountant.
