Yes Maths. Settlor interested.
My understanding is that for a offshore Trust set up in say 2000, by a non-UK domiciled UK resident settlor interested, the trust can continue to invest offshore. The gains are rolled up and taxable only when allocated to a UK resident beneficiary. However the Trust funds much not touch the UK or invest in UK situs assets such as UK Listed shares. Is this correct?
No. If the trust invests in UK situs assets thus potentially receiving UK source income/capital gains no remittance issues arise for settlor and/or beneficiaries.
Indeed
UK source capital gains are are treated as non-UK source where a beneficiary is non-UK domiciled thus permitting remittance basis treatment for such beneficiary (under s87) despite the original UK source nature of the gains.
Also, I understand that when an allocation is made to a beneficiary the recent gains ared deemed to be remitted first (rather than pre March 2008 exempt gains). Is there a way of segregating these old gains from the new ones? I guess onc could always the new gains to a non UK resident beneficiary first leaving clean funds for the UK resident one. I wondered whether there were any other ways.
With respect to capital gains of the trust arising on or after 6th April 2008, yes, the LIFO basis applies; the rules pre 6.4.08 continue to apply to pre 6.4.08 trust gains.
Pre 6.4.08 gains of the trust comprise realised gains and pro-rata gains rea;ised post 6.4.08 (ie where the trust has made a rebasing election).
Unless the trust segregated the pre 6.4.08 gains ab initio no such separation is possible post 5.4.08.
Normal option is, as you indicate, to make capital payments to non-resident beneficiaries thus "washing out" any trust gains prior to capital payments to resident beneficiaries.
I take it you are not just a member of the public, joepublic??
