So is that a submission which the vast majority on askaboutmoney would agree with?
Obviously, the best would be making ETFs work as part of the CGT rules.
Dividends should be considered capital gains (unless the owner is a senior employee of the company, and can abuse the rule to convert salary into capital gains).
Failing that, I suggest making deemed disposal much less of a hassle.
At the moment, you have to track each individual transaction. Each purchase has to be individually handled on its 8th anniversary.
So, keep deemed disposal, but have it happen only once every 8 years. All ETF activity in that 8 years period is taxed in one go.
Effectively, the deemed disposal would mean that you must nominally sell & re-buy
all your ETFs on the 8th anniversary of your oldest ETF.
This resets them all to age 0 and then 8 years later you will have to do it again.
This means a slightly higher tax payout, but that can be compensated by reducing the rate slightly, to keep it revenue neutral.
Keeping it simple.
You just need 4 numbers.
Start value: total value of all ETFs at start of period [*]
End value: total value of all ETFs at end of period
Proceeds: total cash received by selling ETFs in the period
Cost: total cash spent on buying ETFs in the period
[*] The start value must equal the end value of the previous period, when the last tax was paid, or zero for the first cycle
It might be worth limiting ETFs to index funds that cover at least a country, if that makes it easier politically.
I would also treat distributing and accumulating ETFs the same, but that is just me. The dividends from distributing ETFs would just count as extra proceeds and be tax free otherwise.
Calculation
ETF gain: (Start value) - (end value) + (proceeds - cost)
tax payable = rate * (ETF gain)
This is really simple to work out. If you sell the ETFs the day before the end, it is still included in the gain as proceeds. Also, anything you spend on the ETFs is deducted as cost.
There is an issue with time value of money, since cash is not index linked, but this keeps everything simple and people only have to do it once every 8 years.
It may hit people who make a small purchase, and then 7 years later make a big purchase, but even then it is still only the gains that are taxed. They just have to do deemed disposal on any gain on the big purchase after 1 year.
The rule could allow making payments early, but 8 years is the max delay. Alternative, you could allow (but not require) that the period can be broken up into parts. I don't think it matters that much, each person will have an ETF year based on when they initially buy ETFs.
Finally, this rule allows offsetting losses in one ETF against gains in another.
DD was introduced to prevent somebody doing gross rollup forever, and never paying tax.
Which is funny since you can do that with CGT. If you invest in stocks and then wait until you die, your heirs don't have to pay CGT on gains up until your death.
The idea is that they pay CAT instead, but that is often eliminated due to thresholds.
Maybe they should change it so that you can offset CAT payments against the CGT. Ofc, the family home is exempt from CGT anyway.
