..If it is an interest-in-possession trust all shares are listed on the IHT 400 and I understand that we inherit them at their value at the time of my uncle’s death.
....But, if it is ........ a discretionary trust, does my uncle’s death mean that the shares that are in the Trust are passed on to myself and my brothers at the value on the day of his death? Or will we have to pay capital gains tax when we sell them using the value that they had when the Trust was set up (i.e. 1976)?
I suggest that your biggest concern at this time should be the correct meaning of the wording in your grandfather’s will, about which you are intending to take professional advice; that wording determines the type of trust and hence its taxation as well as the trustees’ powers, including that to distribute capital to you (and your siblings).
You write that you have acted since you became a trustee in 2008 as though the trust was discretionary.
But, on the other hand, you are now hoping that your uncle had the entire interest in possession because of the uplift benefit for CGT that you describe correctly. However, if your uncle did had not have any interest in possession pre 2006 (and so the assets were relevant property in the parlance since the 2006 legislation) as Maths previously commented in his post above, your uncle’s death does not per se engender any requirement for IHT/CGT returns re the trust and any subsequent distribution of capital to you may result in IHT and/or CGT payable by trustees of a value that will not be affected by his death.
