Deemed Disposal Calculator

The day you stop being an Australian tax resident, the ATO treats you as having sold every non-property asset you own at market value, shares, crypto, funds, most private company equity. That’s CGT event I1: a real tax bill with no sale and no proceeds.

You get one alternative: elect to defer, which keeps each asset inside the Australian tax net until you actually sell, with all future growth taxable here and the 50% discount frozen while you’re away. This tool prices both paths for your actual portfolio, asset by asset, and shows what shifting the departure date one financial year does to the bill.
