Scenario is as follows:
Net Value of Estate £450K. Donor and spouse aged 65 and 60 respectively and are preparing to claim state pension. No asset transfers have taken place whatsoever. The donor and spouse have adult children: a son and two daughters. The son has taken an active interest in the family affairs and the daughters are married and independent.
Donor traded 31 yrs, as sole trader from freehold commercial property part of which is his main residence. (Accommodation above shop). Property has a single deed hence no split of deeds between residential to commercial has taken place.
5 years ago Donor ceased trading and commercial portion of building including all business assets was let on 1 yearly renewable licences (i.e. held control of fixtures, fittings and equipment though ceased trading). Donor, subsequent to ceasing trade, travelled to and fro from UK leaving spouse to collect rental Income. The 3rd licensee left the commercial property few moths ago and the Donors son took over the premises under the same conditions trading as a private limited company and paying rent to mother (Donors spouse).Taking into consideration the following: The nil rate band, Business Property Relief, inter spouse exemptions satisfying IHT regulations - Taper Relief and holdover relief under CGT regulations. The age of the donor and spouse and the fact that the donor had ceased trading but has not disposed business assets and further the availability of the son as heir and the sons current business activity trading as a limited company under a license in the fathers property.
What is the best way forward in order to keep IHT and CGT liabilities minimised if not nil.
