Calculating Vehicle Registration Tax

Assessing the value

For category A and most category B vehicles, the value of the vehicle is used in calculating the VRT due. This value is known as the Open Market Selling Price (OMSP). This is usually slightly different to the invoice value of a vehicle.

The VRT calculator

You can find the OMSP for a particular vehicle and estimate of the tax due on the VRT calculator. There are over 25,000 valuations on the VRT calculator.

The VRT calculator will usually give a good estimate of the VRT due if registering a particular vehicle on that same day. However, this is an estimate only. Revenue only calculate the exact VRT due when a vehicle is presented for registration.

Determining an OMSP

If a vehicle is not on the calculator, Revenue will determine its OMSP, but only after it is presented for registration. Revenue uses market indicators such as UK and Irish trade guides, advertisements, and experts. Revenue staff do not provide estimates for vehicles that have not been presented for registration.

If a vehicle is not listed and you need an OMSP estimate before buying then you must conduct your own research. The VRT Estimate Form may be used for makes that are not commonly distributed in Ireland.

Other factors affecting the OMSP

For VRT purposes, vehicles may be rated as good, fair or poor. In general, most vehicles are rated as good. A fair or poor rating may reduce the VRT that is due.

Mileage that is considerably higher than accepted 'norms' might reduce the VRT that is due. Revenue assume the normal average monthly mileage is 2,100 km for diesel vehicles and 1,500 km for all other vehicles.
