Commentary on Sections Example 3 £150(Pe) – £50(E) = £100 Section 133: How to determine the “appropriate percentage”
497.This section is the first of a group of ten defining “the appropriate percentage” to be used in Step 6  of section 121(1) of this Act to calculate the cash equivalent of the car benefit. The “appropriate percentage” depends on the type of car involved, when it was first registered, what fuel or fuels it uses and whether it has a CO2 emissions figure. The section derives from paragraph 2 of Schedule 6 to ICTA.
498.Subsection (1) identifies the date of the car’s first registration as the initial governing factor.
499.Subsection (2) applies different provisions to cars first registered after 31 December 1997, depending on whether or not they have a CO2 emissions figure and/or whether they are diesels. It gives signposts to the relevant provisions in each case.
500.Subsection (3) gives a signpost to the provision that applies if the car was first registered before 1 January 1998.
