Between choosing US domiciled or Irish domiciled, has anybody done research on estate taxes? I read somewhere US estate taxes pretty high. It would be sad if you buy and buy and buy and buy and hold US domiciled ETFs for long term. And one day accident happens, and estate tax comes in, US government takes 40% of your portfolio.

Yes, withdraw before you die.

Assets subject to US estate tax
Non-US domiciliaries are taxed only on the value of their US “situs” assets. US situs assets generally include real and tangible personal property located in the US, business assets located in the US, and stock of US corporations. The definition of US situs assets may be modified by an applicable estate and gift tax treaty.


An exemption of $60,000 is available against the value of assets includable in the US taxable estate of an individual who was not US domiciled. Maximum tax bracket, 40%

This why I'd rather invest in Irish domiciled funds, then can sleep peacefully.
I think there's no such thing as estate tax or inheritance tax for non-Irish residents.

I also not really sure.

May I know why the recommendation is TradeStation?
Why not use IBKR directly?
If using IBKR, is it better to use IBKR US or IBKR EU?
