We wanted to bring to your attention upcoming changes to emissions testing for plug-in hybrid vehicles (PHEVs). These changes, outlined in the article linked below, may affect real-world CO2 emissions ratings and, as a result, the Benefit-in-Kind (BIK) tax rates for some PHEV models starting in 2025.
The revised emissions standard will apply to all newly launched PHEVs from 1st January 2025, and to all existing models on sale by 31st December 2025. As part of this change, all current PHEV models must undergo re-homologation before the end of 2025.
Company car tax rates will be based on the emissions figure applicable from the car’s production date. For example, under the updated standards, the BIK rate for a model like the X1 could rise from 8% to 24%.
