Most investors are familiar with the arrangements that can be made to make full use of their capital gains tax annual exemption. Each UK-resident individual has the benefit of an annual exemption from CGT (unless that allowance is barred because they are non-UK domiciled and claim the remittance basis of taxation).
Any unused annual exemption (£10,100 for 2009/10) cannot be carried forward. However, if the person wants to reduce future CGT liabilities, triggering gains up to the available exemption will mean no tax to pay for 2009/10 but also sheltering future gains when the time comes to dispose of the shares finally.
There are rules that counter ‘bed and breakfasting’ by selling and reacquiring shares of the same class within thirty days but they don’t apply to sales where the shares are reacquired by a spouse or civil partner, or by another related entity, such as an ISA or a family trust.
That is one of the simpler but more effective forms of tax planning.
Where shares have fallen in value it is possible to take the planning one stage further by selling the loss-making shares to realise the losses now and carry them forward to use against future gains. Again, if one wishes to retain a holding of the shares, a spouse, civil partner, trust or ISA may be the re-acquirer of the shares.
Losses crystallised in this way don’t have to be carried forward: a person who has already made gains exceeding the annual exemption this year may use this technique to generate losses that can be set against those gains.
As ever, consideration needs to be given as to the commercial/investment merits of doing this.
