This is one of the key problems with the current CGT changes - you take 10 years of capital gains but get taxed as if it happened in a single year. The 9 years you deferred the gain don’t get factored in at all and so you’re taxed as if you’re in the top 1% of income earners when, over the course of 10 years, you’d likely be just above average.
All the talk about “it’s taxed the same as earned wages” is plain wrong.
Without averaging (which Chalmers is not reintroducing, despite the misleading “returning” rhetoric) capital gains that have accrued over multiple years (eg 10 years) are made subject to a single year’s tax brackets.
Bracket creep on steroids for CGT.
