Income Tax (Earnings and Pensions) Act 2003

Section 330: Prevention of double deductions

1414.This section is the third of four which sets out a general proposition relating to deductions from earnings. It deals with the prevention of double deductions.

1415.The proposition in this section is not articulated in general terms in ICTA, although it seems true as a matter of income tax law. There are statements of this proposition in particular contexts in sections 194(9), 195(12) and 198(3) of ICTA.

1416.Subsection (1) sets out the general rule: a deduction from earnings under this Part is not allowed more than once in respect of the same costs or expenses.

1417.Subsection (1) is expressed to apply to “costs and expenses”. These words are intended to cover all potential deductions under this Part, even though the amount of the deduction may not be computed by reference to an actual amount of expenditure – as is the case under Chapter 4 of this Part, which deals with fixed allowances for employee’s expenses.

1418.Subsection (2) deals with the case where a cost or expense qualifies both for an allowance under Chapter 4 of this Part and for a deduction under some other provision. In such a case only one of the deductions is allowed. This provision codifies Inland Revenue practice on these topics. See Change 82 in Annex 1.
