Section 163: Deduction for deemed employment payment
666.This section sets out the trading income rules that were originally part of the “IR35” scheme for the taxation of workers supplied by an intermediary. It is based on paragraph 17 of Schedule 12 to FA 2000. The worker is treated as receiving a “deemed employment payment” and is taxed accordingly (see Chapter 8 of Part 2 of ITEPA). This section ensures that an equivalent amount (and no more) is allowed as a trading deduction in calculating the profits of the intermediary.
667.Subsection (1) sets the scene, using expressions that are defined in subsection (5) by cross-reference to the employment income rules in ITEPA.
668.Subsection (2) identifies the amounts that are allowed as trading deductions.
669.Subsection (3) is a timing rule. Generally, the deemed employment payment is treated as made at the end of the tax year (see section 50(3) of ITEPA). In some circumstances the payment is treated as made earlier (see section 57 of ITEPA). In either case, the trading deduction is given for the period in which the payment is treated as made.
670.Subsection (4) is the rule that prevents any double deduction. It caters for the possibility that the payments may qualify as trading deductions on first principles and for the possibility that the payments may also qualify as trading deductions in a period of account different from that specified in subsection (3).
