For 5% extra tax? That's why I didn't say raise capital gains to be equal to income tax. Which would be fair (it's not fair that active work is taxed more than passive income) but would have unintended consequences. Someone selling and willing to pay 20% tax (on CG over 100,000) isnt going to be automatically put off paying 25% tax (on CG over 100,000) unless they believe it's a very temporary situation and likely to go down the next year. Which is why stability and being able to demonstrate the reasons in favour/bring the public onside is important. Because that way, even a newly elected government would struggle to change it back (and risk losing revenue AND public support). And so long as the people contemplating selling are aware of this.
Someone who made a profit of 150,000 from selling (that's not how much money they have, just the amount of money their money made) would be paying an extra 5% of 50,000 so an extra 2,500. You couldn't even buy a decent Rolex for that.
