Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate her Department has made of the fiscal cost of Benefit-in-Kind rates for zero-emission company cars, including (a) the cost of the 3 per cent rate in 2025–26, (b) the revenue forgone when the rate was 0 per cent and 2 per cent, and (c) any comparable figures for plug-in hybrid and ultra-low-emission vehicles.

The Government publishes annual statistics on HMRC’s taxable benefits in kind for company cars. These reports document the number of benefit in kind recipients, the CO2 emissions of company cars and their total taxable value. The latest statistics for the tax year 2023-24 were published in June 2025, and are accessible here: https://www.gov.uk/government/statistics/benefits-in-kind-statistics-june-2025/benefit-in-kind-statistics-commentary-june-2025(opens in a new tab)
