How NSW calculates car stamp duty
For passenger vehicles, Revenue NSW charges $3 for every $100 (or part) of market value up to $44,999. From $45,000 the duty is $1,350 plus $5 for every $100 above $45,000. This is marginal: only the part above $45,000 is charged at the higher rate, so there is no cliff edge.
For a new car, duty is based on the price you paid including GST. For a used car it is the higher of the sale price and the market value. Factory rebates do not reduce the dutiable value, and the extra cost of an extended warranty is not included.
NSW car stamp duty calculatorHow Victoria calculates car stamp duty
Victoria charges a rate per $200 (or part) of the entire market value, and the rate depends on which band the value falls into. For 2026–27 the first band ends at the luxury car tax threshold for other vehicles, $80,809, as set by the ATO.
| Market value | Rate per $200 | Effective rate |
|---|---|---|
| Up to $80,809 | $8.40 | 4.2% |
| $80,810 to $100,000 | $10.40 | 5.2% |
| $100,001 to $150,000 | $14.00 | 7% |
| Over $150,000 | $18.00 | 9% |
Because the rate applies to the whole value, crossing a band boundary by one dollar raises the duty on the entire car. At $80,809 the duty is $3,402.00; at $80,810 it is $4,212.00 — about $810 more for a $1 higher price.
NSW vs Victoria: duty on the same car
NSW is cheaper at every price in this table for a standard petrol or diesel car. The gap is modest below $80,000 but widens sharply above Victoria’s band thresholds. A Victorian green car keeps the $8.40 rate, which makes it cheaper than NSW from about $112,600 upwards.
| Car value | NSW | VIC standard | VIC green car | Cheaper |
|---|---|---|---|---|
| $15,000 | $450 | $630 | $630 | NSW |
| $25,000 | $750 | $1,050 | $1,050 | NSW |
| $35,000 | $1,050 | $1,470 | $1,470 | NSW |
| $45,000 | $1,350 | $1,890 | $1,890 | NSW |
| $60,000 | $2,100 | $2,520 | $2,520 | NSW |
| $80,000 | $3,100 | $3,360 | $3,360 | NSW |
| $90,000 | $3,600 | $4,680 | $3,780 | NSW |
| $100,000 | $4,100 | $5,200 | $4,200 | NSW |
| $120,000 | $5,100 | $8,400 | $5,040 | NSW |
| $150,000 | $6,600 | $10,500 | $6,300 | NSW |
When car stamp duty is payable
Dealers usually include duty in a drive-away price; in a private sale the buyer pays it when transferring the registration.
- When a new vehicle is registered for the first time.
- When registration of a vehicle is transferred to another person (for example, buying a used car privately).
- When an imported second-hand vehicle is registered in the state for the first time.
Budgeting for the full cost
Stamp duty is one of several on-road costs, alongside registration, compulsory third-party insurance and dealer delivery. Because duty is calculated on a GST-inclusive price, you can check how much GST is inside a quote with the Australian GST calculator. If you are financing the car, add the duty to the amount you need and test repayments with the loan calculator.
