Income Tax (Earnings and Pensions) Act 2003 section 127

The list price of an accessory

Section 127 defines how to determine the list price of an accessory fitted to a company car for the purposes of calculating the car benefit charge.

• An initial extra accessory's list price is the published price from the car's manufacturer, importer, or distributor.
• If the car's manufacturer, importer, or distributor has no published price for the accessory, the published price from the accessory's own manufacturer, importer, or distributor is used instead.
• A later accessory's list price is always the published price from the accessory's own manufacturer, importer, or distributor.
• The distinction between initial extra accessories and later accessories determines which pricing source takes priority.
