Depending on the country-specific rules on CGT, dividend tax, stock exchange tax, … it can make more sense to choose one version over the other.
E.g. there is no CGT in Belgium (usually), but there is a dividend tax so the most sensible version is to go for the Accumulating ETF with a fund domicile in Ireland (US double taxation treaty 15% withholding tax, no additional Irish taxes on income received by the fund, no additional local taxes as the fund doesn’t distribute).
Some countries even allow to reclaim the 15% withholding tax on dividends the Irish fund pays on US-source dividends.
Does this exist in the UK? I.e. is it possible to reclaim the 15% withholding tax of a distributing ETF when it is in an ISA? I remember reading that it is possible to reclaim this with a SIPP in some cases.
There could be an impact on compounding as well for Acc vs Distr, but let’s assume zero transaction costs and reinvesting the distributed income immediately in the ISA.
