ICTA88/S780 deals with the situation where the existing occupier of premises incurs additional rental liability for a comparatively short period in return for the payment of a lump sum.
ICTA88/S780 applies to leasebacks:
Where ICTA88/S780 applies, a proportion of the lump sum is to be
treated as income of the recipient.
For example, where a lease is for 15 years, l4/l5ths of the
lump sum is to be treated as a capital receipt of the lessee and
1/15th as an income receipt. In the case of leases for shorter
periods, the capital element is to be correspondingly smaller and
the income element greater.
A professional partnership:
The commercial rental value of the premises on 1 June 2003 is
approximately £100,000 per annum.
Since the rent of £70,000 per annum is less than the
commercial rent, no restriction is required under ICTA88/S779 (4).
The income proportion of the £200,000 is 8/15ths, that
is, £106,666.
The balance of £93,334 is within the charge to CGT.
