How Does It Work?

The calculator requires inputs such as the Original Market Value (OMV) of the vehicle, the annual business mileage, and the CO2 emissions category. It then applies the appropriate percentage based on Revenue’s 2025 BIK guidelines, providing the taxable benefit amount. For electric vehicles, the calculator automatically applies the €35,000 reduction in OMV for the 2025 tax year.

Why Is BIK Important?

Benefit in Kind is a form of non-cash income an employee receives from their employer, which is subject to tax. For company cars, it refers to the taxable benefit associated with using the vehicle for personal purposes, and must be accurated calculated to avoid taxation errors and penalties.
