Devil is in the detail.

We have a half decent CGT that charges people at their top rate, not the usual 15-20% mooted. It's just tricky for IRD to prove intent... a tweak to move onus onto the tax payer to prove intent (or lack thereof) would go some way to addressing that without too much political hoo-ha.
Quite right, except that IRD does require the taxpayer to demonstrate intent, on request. And those currently paying income tax on capital gains would be laughing all the way to the bank if they only had to pay 15%.
