What is the best way to invest in Ireland-Domiciled S&P 500 ETFs?

Interactive brokers charge a minimum monthly fee of S$10 for accounts with balance between S$2,000 and S$100,000. i suggest if you're buying and holding, use stanchart online trading. you only need to pay a one time brokerage amount. there's no other monthly fees / custodian fees.

Interactive brokers is good.

Hey there, you can actually use and of the online brokerages on the Seedly platform which are in this list here: https://seedly.sg/reviews/online-brokerages

I would say two of the more compeitive ones are FSM ONE and SAXO for a modern interface and also relatively lower charges for US stocks. (even though Ireland Domiciled)

However, thing to note is that some in the community often use Interactive Brokers as well (for accounts funded more than USD10k) so that's one which you can consider as well.

Cheers!

Interactive Brokers is the recommended broker due to its lower fees. However, I wonder if it is a good idea to set up a brand new broker account just to buy Ireland domiciled ETF. The time and effort spent might outweight the lower withholding tax rates.
