Stamp Duty Calculator for Cars NSW: 2025 Guide

Understanding Stamp Duty on Car Purchases in NSW

Stamp duty in NSW is a government charge applied when transferring vehicle ownership, calculated based on the vehicle’s value and buyer details. For 2025, the system has evolved to offer greater transparency and fairness, especially with updated digital tools and exemption thresholds. If you’re buying or selling a car in NSW, knowing how stamp duty applies is essential to budget correctly and avoid surprises at registration.

What Is Stamp Duty and How Is It Calculated in NSW?

Stamp duty is a state levy on car transfers, administered by the NSW Treasury. The calculation uses the vehicle’s gross value, buyer’s residency, and whether the car is new or used. As of 2025, the standard formula applies: duty increases progressively up to a threshold, after which it plateaus. For example, a vehicle valued at $75,000 faces a flat rate after reaching the upper threshold, simplifying planning. The system also rewards eco-friendly choices—electric vehicles (EVs) often benefit from reduced or zero duty under NSW’s green incentives.

• Up to $75,000: duty at 12.5%
  
• Between \(75,001 and \)150,000: flat rate of 50% on the amount above $75,000
  
• Above \(150,000: 6.5% on the entire value For example, a \)120,000 used car triggers 50% duty on \(45,000 (\)22,500), while a \(200,000 new car incurs 6.5% on \)125,000 ($8,125).
