Australia · Stamp Duty
The Northern Territory is the outlier: a flat 2.24% applies to every dollar up to $525,000, which makes duty on mid-priced homes lower than any state, but there is no first-home exemption at all — even a $350,000 first purchase pays $7,840. Above $525,000 the rate jumps to 5.99%, so the marginal cost of stepping up from $500,000 to $600,000 is steep. Buyers upgrading in Darwin's tighter market should model the jump carefully.

The buyer pays the tax in essentially every case in this market. It is payable in full before or at settlement and cannot normally be added to a mortgage, so it must be part of your cash budget alongside the deposit.
How we calculate: the calculator applies the official band schedule marginally — each rate applies only to the slice of the price inside its band, exactly as the revenue authority does. Worked examples are computed with the same function.
