A charge to income tax and, if appropriate, NICs, occurs on the
occasion of a chargeable event (per ITEPA03/S426). The taxable
amount arising on the occasion of the chargeable event is treated
as employment income of the employee for the tax year in which the
chargeable event occurs (“the relevant tax year”).
There are exemptions in certain cases of control, where the
event will not be a chargeable event – see
ERSM20290.
There are three types of chargeable event:
The variation of a restriction includes the removal of a
restriction, so for a security with a number of restrictions
attached, a chargeable event will occur on each and every occasion
that one of the restrictions is removed or comes to an end by the
passing of time.
When the securities are subsequently disposed of, relief is
available for the amount charged to tax under Part 7 ITEPA03 for
the purposes of the capital gains tax computation (see CG56354 and
CG56355)
