VRT Calculator (Ireland)

Ireland VRT Calculator 2026: Your Complete Guide to Vehicle Registration Tax

If you are planning to import a car into Ireland from the UK, Northern Ireland, Japan, or any other country, registering your vehicle with the Revenue Commissioners is a mandatory step. During this registration at the NCT (National Car Test) centre, you are required to pay the Vehicle Registration Tax (VRT).

Calculating VRT manually can be confusing due to the frequently changing budget rules. Our advanced Ireland VRT Calculator is updated with the latest 2026 tax bands, making it incredibly easy to estimate your CO2 charges, NOx levy, and potential EV reliefs in just a few clicks.

1. What is Vehicle Registration Tax (VRT)?

VRT is a tax imposed by the Irish government on motor vehicles when they are registered in the State for the first time. Whether you are bringing a second-hand car across the border or importing a brand-new model, VRT applies. The total VRT amount you pay is primarily based on three factors:

• OMSP: The Open Market Selling Price of the vehicle in Ireland.
• CO2 Emissions: Based on the WLTP (Worldwide Harmonised Light Vehicle Test Procedure) testing system.
• NOx Emissions: A surcharge applied to petrol and diesel vehicles based on Nitrogen Oxide pollutants.

2. Understanding OMSP (Open Market Selling Price)

The most common mistake people make when calculating VRT is using the price they paid for the car abroad. The Irish Revenue does not use your purchase price. Instead, they use the OMSP.

The OMSP is what Revenue estimates your exact car (make, model, year, mileage, and condition) would sell for at a dealership within Ireland. If you bought a car for €15,000 in the UK, but its market value in Ireland is €20,000, your VRT will be calculated on the €20,000 figure.

3. The CO2 Component & Tax Bands (Category A Vehicles)

For standard passenger vehicles and SUVs (Category A), the VRT rate is a percentage of the OMSP. This percentage is determined by how much CO2 the car emits. The cleaner the car, the lower the percentage.

Note: This table shows sample bands. Our VRT Calculator automatically applies the exact tier based on the precise g/km value you input.

4. The NOx Levy Explained

Introduced to combat air pollution, the Nitrogen Oxide (NOx) charge is applied to all internal combustion engine (ICE) vehicles, including hybrids. It operates on a progressive "polluter pays" scale:

• First 40 mg/km: Charged at €5.00 per mg.
• Next 40 mg/km (41-80mg): Charged at €15.00 per mg.
• Anything above 80 mg/km: Charged at a heavy €25.00 per mg.

Revenue Caps: To prevent astronomical fees on older vehicles, Revenue caps the maximum NOx charge at €600 for petrol vehicles and €4,850 for diesel vehicles. Fully Electric Vehicles (EVs) have zero tailpipe emissions and completely bypass the NOx levy.

5. Electric Vehicle (EV) VRT Relief in 2026

To encourage the adoption of greener transport, Ireland offers significant tax incentives for Battery Electric Vehicles (BEVs). If you are importing an EV, the rules are highly favorable:

• Vehicles up to €40,000 OMSP: Receive a maximum VRT relief of €5,000. Because the EV tax rate is a flat 7%, a €40k EV would normally owe €2,800 in VRT. With the relief, the VRT drops to €0.
• Vehicles between €40,001 and €50,000 OMSP: The €5,000 relief tapers off at a rate of 50%. For example, an EV valued at €45,000 receives €2,500 in relief.
• Vehicles over €50,000 OMSP: No VRT relief is granted. You will pay the standard 7% rate on the full OMSP.

6. Category B Vehicles (Commercials and Vans)

If you are importing a commercial vehicle or a van weighing under 3.5 tonnes, it falls under Category B. The VRT calculation here is much simpler and recently updated to favor lower emissions:

• If the vehicle emits 120g/km of CO2 or less, the VRT rate is a flat 8% of the OMSP (subject to a minimum charge of €160).
• If the vehicle emits more than 120g/km of CO2, the VRT rate increases to 13.3% of the OMSP (subject to a minimum charge of €266).

How to Use the TrueAI VRT Calculator

We've designed our tool to be the fastest and most accurate online estimator for the Irish market. Here is how to use it:

1. Enter OMSP: Research your car's market value in Ireland and input that number.
2. Select Category: Choose Category A for passenger cars or Category B for light commercial vans.
3. Choose Fuel Type: Select Petrol/Hybrid, Diesel, or Fully Electric. This automatically configures the NOx settings.
4. Input Emissions Data: Enter the CO2 (g/km) and NOx (mg/km) values. You can usually find these on the vehicle's V5C logbook or a previous NCT certificate.
5. Calculate: Click the button to get an instant, detailed breakdown of your VRT liability, including any applied caps or EV reliefs.
