You may end up spending more on trading fees buying EU domiciled funds than you will save on dividend taxes at 20k/month investment.
For what it's worth, I also invest HK$ 20000 monthly on Irish domiciled ETFs using IBKR, rebalance quarterly.
ISAC 90%
LCAS 10%
I have a long term time horizon 25+ yrs.
Trading costs are cheap (few dollars) and no monthly fees, the only pain is rebalancing, you either have to work it out yourself on Excel and manually trade on the mobile app or use their TWS trading app which can be very frustrating.
I was thinking about opening a Sofi account just for fun (already have an interactive brokers account). Is Sofi a scam/ poor servicing though? They have many negative reviews on Google...
