How is use of a company van taxed?
Where you have the private use of a company van, you are taxed on notional pay equivalent to 5% of the van’s original market value (OMV), less an amount you make good to your employer.
The BIK charge does not apply in relation to vans, provided that the van is essentially for the purposes of your work, that your employer requires you to bring the van home, that other private use was prohibited and that you spent most of your working time away from your employer’s workplace (Department of Finance website).
