For Class 1A NICs liability to arise the benefit must be
provided to an employed earner from, or by reason of, his
employment.
In most cases it will be the employer who is meeting the
cost of providing the benefit and the condition that the benefit
must be provided from, or by reason of, the employment will be
satisfied.
Full guidance on both of these tests is contained in the
Employment Income Manual at
That guidance applies equally for the purposes of Class 1A NICs.
If a benefit is provided and it is not from or by reason of the
employment, there can be no Class 1A NICs liability. Subject to one
exception, all sums paid to an employee by his employer in respect
of all benefits provided for him by his employer (section 201(3)
ITEPA 2003; before 6 April 2003 - section 168(3) of ICTA 1988) are
deemed to be made or provided "by reason of the employment".
The one exception is when the employer is an individual and
he can show that the payment was made or the benefit was provided
in the normal course of his domestic family or personal
relationships. So, a father who employs his son will normally be
able to show that a Christmas present he gives to his son is not
"by reason of the employment". Section 201(3) ITEPA 2003 refers
(before 6 April 2003 – section 168(3) ICTA 1988).
