Irish VRT Estimate Calculator
Use this tool to estimate Vehicle Registration Tax (VRT) based on OMSP, CO2 emissions, NOx emissions, and fuel type.
This is an educational estimator and not an official tax assessment. Final charges can vary based on Revenue rules, reliefs, and vehicle classification.
What Is VRT?
VRT stands for Vehicle Registration Tax. In Ireland, it is generally charged when a vehicle is registered in the state for the first time. The amount can vary significantly depending on the vehicle’s open market value, emissions profile, and any qualifying reliefs.
If you’re importing a car or trying to compare vehicles before purchase, a VRT calculator can help you estimate the likely tax bill so you can budget more accurately.
How This VRT Calculator Works
This calculator uses a simplified method to estimate total VRT:
- Adjusted OMSP: OMSP reduced by your depreciation input.
- CO2-based VRT: A percentage rate is selected from a CO2 band table.
- NOx Levy: A separate charge based on NOx emissions tiers.
- EV Relief: For electric vehicles, a relief is applied to the VRT component (up to €5,000 in this model).
The final estimate is shown as a detailed breakdown so you can see exactly where each part of the total comes from.
Input Guide
1) OMSP (Open Market Selling Price)
OMSP is the Revenue-assessed retail value of the vehicle in Ireland, not necessarily what you paid abroad. It has a large effect on the final VRT amount.
2) CO2 Emissions
CO2 emissions are used to determine your VRT percentage band. Lower-emission cars often attract lower VRT rates.
3) NOx Emissions
NOx (nitrogen oxides) is charged in tiers. Higher NOx readings can add a meaningful levy on top of the VRT amount.
4) Depreciation / Age Adjustment
Older vehicles may have a lower adjusted market value. Use this field to test different scenarios and understand sensitivity in your estimate.
Worked Example
Suppose you enter:
- OMSP: €30,000
- Fuel Type: Petrol
- CO2: 120 g/km
- NOx: 50 mg/km
- Depreciation: 10%
The calculator first adjusts OMSP to €27,000, then applies the CO2 band rate to estimate base VRT. Next, it adds the NOx levy. The resulting figure gives you a practical planning estimate before you commit to purchase.
Tips to Avoid Surprises
- Check emissions data from official vehicle documentation.
- Budget for additional import costs like VAT, customs duty, and transport where relevant.
- Compare multiple cars by running side-by-side calculator scenarios.
- Use the estimate early in the buying process so tax costs don’t derail your budget.
Frequently Asked Questions
Is this calculator official?
No. It is an educational estimate tool designed for planning. Always confirm details with official Revenue guidance or a qualified professional.
Why is my estimate different from final VRT?
Final VRT may differ due to exact vehicle categorization, Revenue OMSP assessments, current relief schemes, and legislative updates.
Can this help with electric vehicle planning?
Yes. It includes a simple EV relief model so you can compare electric and non-electric scenarios quickly.
