EIM24655 | Car benefit calculation Step 5, appropriate percentage, 2012 to 2013 onwards: car with an approved CO2 emissions figure: relevant threshold

From HM Revenue & Customs · Employment Income Manual

Section 139 ITEPA 2003

The relevant threshold applies from 2012 to 2013 only.

The relevant threshold

This page relates to step 5 of the method statement in section 121(1) ITEPA 2003, see EIM24015.

The relevant threshold is the approved C02 emissions figure upon which all calculations of the appropriate percentage are based from 2012 to 2013 onwards.

The relevant threshold has been specified for the following tax years:

Tax yearRelevant threshold, g/km (generate per kilometre)
2012 to 2013100
2013 to 201495
Calculating the appropriate percentage from the relevant threshold

The appropriate percentage is calculated as follows:

  • if the car’s C02 emissions figure is less than the relevant threshold for the year, the appropriate percentage:

g/km2012 to 20132013 to 20142014 to 20152015 to 20162016 to 2017
00%0%0%5%7%
1 to 505%5%5%5%7%
51 to 755%5%5%9%11%
76 to 9410%10%11%13%15%

If the car’s C02 emissions figure is equal to the relevant threshold for the year, the appropriate percentage is:

Description2012 to 20132013 to 20142014 to 20152015 to 20162016 to 2017
relevant threshold (g/km)10095959595
appropriate percentage11%11%12%14%16%

If the car’s C02 emissions figure exceeds the relevant threshold for the year, the appropriate percentage is the lesser of:

  • the threshold percentage increased by one percent for each 5g/km by which the C02 emissions figure exceeds the relevant threshold for the year

  • 35% (up to 2014 to 2015) and 37% from 2016 to 2017

There is a ready reckoner for the appropriate percentage for a type A car for 2012 to 2013 onwards at EIM24705.
