Assessing the Value (OMSP)
How Revenue finds the Irish market value used to calculate VRT.
For Category A (cars/SUVs) and most Category B vehicles, VRT is based on the Open Market Selling Price (OMSP) — Revenue’s view of the Irish retail value at registration. It’s not always the same as your invoice price. The VRT calculator can give a strong estimate, but the exact figure is confirmed when the vehicle is presented for registration.
Using the VRT Calculator
Revenue’s calculator holds over 25,000 valuations. If your exact model is listed, you’ll usually get a good day‑of‑registration estimate. Remember it’s still an estimate until inspection.
If your car isn’t listed
If a vehicle is missing from the calculator, Revenue determines the OMSP after the car is presented. They reference Irish and UK trade guides, adverts and expert inputs. Revenue staff don’t provide pre‑registration estimates for unlisted vehicles.
Need an indicative OMSP before buying? Do your own research. The VRT Estimate Form can be used for makes not commonly distributed in Ireland.
Condition and mileage
For VRT, vehicles can be rated as good, fair or poor. Most are good. A fair or poor rating may reduce the VRT due. Higher‑than‑typical mileage can also reduce OMSP. As a rule of thumb, Revenue assumes average monthly mileage of around 2,100 km for diesel and 1,500 km for other fuels.
Irish buyer’s note:
OMSP already reflects age and mileage, so there isn’t a separate age table for cars like there is for motorcycles. Focus on getting a realistic Irish retail value for your specific trim and mileage.
