Inheritance Tax on overseas shares

I am a UK resident and I hold non-UK listed shares (e.g. US shares) through a U.K brokerage firm or U.K bank. When I passed away, will my non-UK listed shares held through a UK brokerage firm 1) considered to be UK-based assets or non-UK based assets? 2) subject to UK inheritance tax?

Hi ,
 

If you are UK tax resident at the time of your death, then you world wide assets count towards the value of your estate for inheritance tax purposes. Thank you .
