How SA calculates vehicle stamp duty

South Australia charges stamp duty on a stepped scale: $1 per $100 up to $1,000; then $10 plus $2 per $100 to $2,000; $30 plus $3 per $100 to $3,000; and $60 plus $4 per $100 above $3,000. The same scale covers virtually all passenger vehicles.

At $40,000, you're in the typical new mid-size range — still below the higher-value thresholds that several states use to lift the rate.

SA Stamp Duty on Vehicles rate tiers

Value band Rate
Up to $1,000 $1 per $100
$1,000 – $2,000 $10 + $2 per $100
$2,000 – $3,000 $30 + $3 per $100
Over $3,000 $60 + $4 per $100

Above $3,000 — which covers nearly every car — SA effectively charges about $4 per $100, one of the simpler structures in the country.
