VRT Calculator Ireland 2026
Free VRT calculator Ireland for a 2026 Vehicle Registration Tax estimate using OMSP, CO₂, NOx, vehicle category and EV relief, with a clear route to Revenue’s official lookup.
Vehicle Details
Where do I find the OMSP?
Use Revenue's official VRT enquiry where the exact model is listed. OMSP is Revenue's Irish open-market value, not necessarily the invoice price. If the vehicle is not listed, research comparable Irish vehicles and treat the result as provisional.
Where do I find CO₂?
Check the Certificate of Conformity or foreign registration document. Select NEDC only when the document provides an older NEDC figure that Revenue converts for banding.
Where do I find NOx?
Revenue accepts satisfactory evidence such as a Certificate of Conformity or qualifying registration documentation. A figure in g/km is 1,000 times smaller than the same figure in mg/km: 0.008g/km equals 8mg/km.
Why engine size matters
Category M uses €2 per cc up to 350cc and €1 per cc above 350cc before the age reduction. Electric motorcycles use the separate 2026 exemption rule.
Which registration date?
Use the month and year when the motorcycle first entered service in any country. The age at Irish registration determines the Revenue reduction band.

How this VRT estimate is calculated
This calculator estimates 2026 Vehicle Registration Tax in Ireland from the vehicle category, OMSP, CO₂ emissions, NOx emissions, fuel type, and motorcycle details where relevant.
Published by Irish Calculators. Rates, rules and assumptions are maintained against the official sources linked below.
- For Category A cars, the calculator applies the Revenue CO₂ band to the OMSP to estimate the CO₂ component.
- It then estimates the NOx charge from the NOx figure entered, or applies the maximum diesel/non-diesel estimate if no NOx evidence is selected.
- For qualifying battery electric vehicles registered by 31 December 2026, the calculator applies the tapered EV relief estimate where applicable.
- Category B, Category C, and motorcycle estimates use their own simplified Revenue rule paths, including motorcycle age reduction.
- The result remains a planning estimate only because Revenue confirms final VRT at registration using exact vehicle details and OMSP.

About This VRT Calculator Ireland
This free VRT calculator Ireland page helps you estimate Vehicle Registration Tax before registering or importing a vehicle. It is designed for manual planning where you know, or can estimate, OMSP, CO₂ emissions and NOx emissions.
What it estimates. For Category A cars, the calculator estimates the CO₂ VRT component, the NOx component, electric vehicle relief where relevant, and the total VRT payable. It also includes simplified Category B, Category C and motorcycle estimates.
What it does not do. It does not search by registration number, statistical code, vehicle database, exact Revenue OMSP valuation, chargeable extras, NCTS inspection outcome, or special manual valuation cases. The official Revenue VRT calculator and NCTS process decide the final amount.
Useful internal tools. If you are budgeting for an imported car, you may also want to use the Loan Repayment Calculator, Savings Goal Calculator, and VAT Calculator.
This VRT calculator is for illustration only and does not constitute tax, legal, vehicle import, or financial advice.
Which VRT calculator should you use?
Choose the route that matches the information you have. Irish Calculators gives a transparent manual estimate; Revenue provides the official vehicle-model and statistical-code service.
Use Irish Calculators
Best when you already know, or can reasonably estimate, the vehicle category, OMSP, CO₂ and NOx figures.
- Shows every calculation assumption.
- Includes Category A, B, C and motorcycle estimates.
- Does not need a registration number or statistical code.
Use Revenue's VRT calculator
Best when you want Revenue's current model valuation using a statistical code or the vehicle's exact make, model, version, first-registration date and emissions details.
- Includes Revenue's current OMSP valuations where a model is listed.
- A registration number alone is not a complete calculation input.
- Motor caravans and special-research models may not be available.
VRT rates Ireland 2026
For a Category A car, Revenue applies the percentage below to OMSP, subject to the minimum charge, and then adds the separate NOx charge. The table uses the current WLTP or Revenue-converted CO₂ figure.

|---|---|---|
| 0–50g/km | 7% | €140 |
| 51–80g/km | 9% | €180 |
| 81–85g/km | 9.75% | €195 |
| 86–90g/km | 10.5% | €210 |
| 91–95g/km | 11.25% | €225 |

Each button loads the stated assumptions into the calculator. Revenue confirms the final amount at registration.
€20,000 OMSP · 130g CO₂ · 50mg NOx
€3,500 CO₂ component plus €350 NOx gives an estimated VRT of €3,850.
€12,000 OMSP · 130g CO₂ · NOx missing
€2,100 CO₂ component plus the €4,850 missing-evidence maximum gives €6,950.
€40,000 OMSP · 0g CO₂
€2,800 base VRT is fully offset by the qualifying 2026 EV relief, giving an estimate of €0.
650cc · first registered July 2018
The base charge is €1,000 before Revenue's age reduction. The live result uses today's date to select the correct reduction band.
