How company-car BIK works

OMV × a percentage set by emissions and business mileage.

Since 1 January 2023, Ireland taxes company cars on a CO2-based system. The benefit-in-kind is a percentage of the car's Original Market Value, where the percentage rises with emissions (Category A lowest, E highest) and falls as your annual business mileage increases. Because the taxable benefit is added to your pay and taxed at your marginal rate, moving down a mileage band can be worth a meaningful amount each year — provided the business kilometres are genuine and logged.

Percentages per the CO2-based company-car BIK rules effective 1 January 2023. Revenue: company cars. Estimate only, not tax advice.
