What does OMV mean for company car BIK in Ireland?

OMV means Original Market Value. It is used as the starting point for estimating the taxable benefit base for a company car under Irish BIK rules. The exact value used can depend on classification and the statutory method for the relevant year.

If I do not know the exact OMV, what should I do?

Use your best available estimate and treat the result as planning only. You can refine the OMV later and re-run the calculation to see how sensitive the result is.

Why does OMV change the BIK tax so much?

Because the taxable benefit value is derived from the value base (often OMV, possibly adjusted) multiplied by the applicable BIK rate. Higher OMV tends to increase the taxable benefit value and therefore payroll deductions.

1) Why OMV matters

Company car BIK is based on a statutory taxable value. In many scenarios, OMV is part of the base used to estimate that taxable value. If OMV is higher, the taxable benefit value tends to be higher.

Because payroll deductions can be calculated on a higher taxable base, the BIK impact can show up across PAYE, USC, and PRSI depending on your overall position.

2) What to use as an OMV estimate

If you do not have an exact OMV figure, use a reasonable estimate and then test sensitivity: adjust the OMV up and down and see how the estimate changes. This helps you understand whether the decision is OMV-sensitive.

The goal is not perfection on day one. The goal is a decision-quality estimate that you can refine as you get better information.

3) A simple comparison workflow

Use the company car BIK tool to model your scenario, then switch between years to see how year-specific provisions can change the estimate for the same inputs.

If you are also offered a cash allowance, compare the cash vs car scenarios using the same salary and then treat the difference as an estimate that depends on payroll handling.
