What Is Stamp Duty on NSW Car Purchases?

Stamp duty is a state government tax on property and vehicle transfers. For NSW car buyers, it applies to new and used vehicles based on purchase price, vehicle type, and buyer details. The duty is calculated progressively: higher values incur higher rates, but NSW uses a tiered system with thresholds to limit initial burden.

Key Factors Influencing Stamp Duty in 2025

Several factors determine how much stamp duty you pay on a NSW car purchase:

• Vehicle value: Higher purchase prices trigger higher rates.
• Vehicle type: Cars, motorcycles, and commercial vehicles have separate duty brackets.
• Buyer category: Individual vs. corporate buyers may face different rates.
• State residency: Only NSW residents pay stamp duty on vehicles registered or purchased there.

Step-by-Step Guide to Calculating Stamp Duty NSW Car

To estimate your stamp duty quickly and accurately:

1. Determine the total purchase price including taxes and fees—this is your base amount.
2. Identify the vehicle class (e.g., passenger car, motorcycle, commercial).
3. Apply the duty brackets based on the value tiers for 2025 (e.g., up to \(36,000 at 0.5%, above that up to \)72,000 at 1.5%, etc.).
4. Use the NSW Government’s online stamp duty calculator for instant, official figures.

Example: Calculating Duty for a $55,000 Car

• Base value: \(55,000 falls in the \)36,001–\(72,000 bracket at 1.5% → \)55,000 × 0.015 = $825 stamp duty.
• No additional regional or concession discounts apply for this vehicle and buyer type. This gives a total duty of $825.
