Luxury Tax
Budget 2021 proposed to introduce a tax on the sales, for personal use, of luxury cars and personal aircraft with a retail sales price over $100,000, and boats, for personal use, over $250,000. The tax would be calculated at the lesser of 20 per cent of the value above the threshold ($100,000 for cars and personal aircraft, $250,000 for boats) or 10 per cent of the full value of the luxury car, boat, or personal aircraft. The Department of Finance has undertaken consultations with respect to the design of this measure and is working to incorporate the results of this consultation into the proposed tax framework. Draft legislation, including details on coming-into-force, will be released in early 2022.
