The relief provided an effective exemption for a certain amount of gains on disposals of all or part of a qualifying business, including certain share disposals. It was replaced by the business asset rate of taper relief which was available from 1998-99 to 2007-08, see CG17895+. Certain elements of retirement relief are reflected in entrepreneur’s relief which is available for disposals on or after 6 April 2008, see CG63950+.
FA98/S140 provided for the phasing out of retirement relief from 6 April 1999. The amounts of gains qualifying for relief was reduced annually in equal stages for the years 1999-00 to 2002-03, so that the relief ceased to be available from 6 April 2003.
Guidance on retirement relief is no longer included in this manual. It can be found on the National Archives site as explained at CG10100.
