What Is VRT?

Vehicle Registration Tax (VRT) is a compulsory one-time tax that every vehicle owner in Ireland must pay before their vehicle can be registered and legally driven on Irish roads. It applies to cars, vans, motorcycles, motorhomes, and other motor vehicles that are imported or purchased new in Ireland.

VRT is collected by the Irish tax authority, Revenue (Revenue Commissioners), and is one of the most significant costs involved in importing or purchasing a vehicle. For many vehicles, VRT can represent 20–50% of the vehicle’s value, making it a critical factor in any car-buying decision.

The tax is calculated based on three primary factors: the vehicle’s Open Market Selling Price (OMSP), its CO2 emissions band, and for diesel vehicles, a NOx (nitrogen oxides) levy based on exhaust emissions. These factors combine to produce the final VRT amount you must pay at the National Car Testing Service (NCTS) centre when registering your vehicle.

Every vehicle entering Ireland, whether brand new or second-hand, whether from the UK, EU, Japan, the USA, or anywhere else in the world, is subject to VRT. There is no automatic exemption for vehicles that are already registered in another country. The only exceptions are specific reliefs and exemptions covered later in this guide.

History of VRT in Ireland

Vehicle Registration Tax in Ireland was introduced in its current form as part of a broader overhaul of vehicle taxation in the 1990s. Before VRT, Ireland relied on a system of purchase tax and annual motor tax that did not adequately link vehicle taxation to environmental impact.

The introduction of VRT allowed Ireland to align its vehicle tax system with European Union environmental directives. Over the decades, the system has evolved significantly:

• 1990s: VRT introduced based on engine size as the primary metric
• 2008: CO2 emissions replaced engine size as the primary banding criterion, following EU standards
• 2009: NEDC (New European Driving Cycle) CO2 measurements adopted for banding
• 2020: Transition to WLTP (Worldwide Harmonised Light Vehicle Test Procedure) began for new vehicles
• 2021: NOx levy introduced for diesel vehicles, adding an additional environmental charge
• 2024: Full WLTP adoption for all newly registered vehicles, with NEDC vehicles grandfathered at previous rates
• 2025–2026: Electric vehicle relief maintained at up to €5,000, with progressive band adjustments

These changes reflect Ireland’s commitment to reducing transport emissions and incentivising cleaner vehicles. The shift from engine size to CO2 emissions was particularly significant, as it meant that a large but efficient vehicle could attract lower VRT than a smaller, more polluting one.

How VRT Is Calculated

VRT is calculated by applying a percentage rate to the vehicle’s Open Market Selling Price (OMSP). The percentage rate depends on the vehicle’s CO2 emissions band, which is determined by the WLTP test cycle for vehicles registered from 2021 onwards.

The basic formula is:

VRT = OMSP × CO2 Band Rate + NOx Levy (if applicable)

For example, a car with an OMSP of €30,000 and CO2 emissions of 130g/km (Band 12, 27% rate) would have a base VRT of €8,100. If the vehicle is diesel with a NOx output requiring a €1,500 levy, the total VRT would be €9,600.

It is important to note that Revenue determines the OMSP, not the buyer or seller. Revenue uses a range of market data sources to establish the OMSP, including manufacturer list prices, dealer quotations, and comparable sales data. If you believe Revenue’s OMSP assessment is too high, you have the right to appeal.

Age depreciation can also reduce the OMSP used for calculation. Vehicles over two years old receive age-related discounts to the OMSP, with the discount increasing as the vehicle gets older. This means older imported vehicles may attract lower VRT than their purchase price might suggest.

Understanding OMSP (Open Market Selling Price)

The Open Market Selling Price (OMSP) is the foundation of any VRT calculation. It represents the price at which the vehicle would be sold on the open market in Ireland, including VAT. Revenue determines the OMSP using several methodologies:

• Manufacturer list price: For new vehicles, the Irish dealer list price is the primary reference
• Comparable market analysis: For used vehicles, Revenue examines similar vehicles currently for sale in Ireland
• Dealer quotations: Revenue may request quotes from Irish main dealers for the specific vehicle
• International pricing data: Cross-referencing with pricing in the UK and EU markets

The OMSP includes Irish VAT (23% or 13.5% depending on the vehicle) but excludes VRT itself. This is an important distinction — the OMSP is the pre-VRT retail value, not the total cost to the consumer.

Age depreciation adjustments: For vehicles over two years old, Revenue applies age-based depreciation to the OMSP. The standard schedule is approximately 10% per year for the first three years, then a further percentage for each subsequent year, up to a maximum of 70% reduction for vehicles over 10 years old. This means a 5-year-old vehicle might have its OMSP reduced by around 30–35% compared to its new equivalent.

Use our OMSP Calculator to estimate your vehicle’s Open Market Selling Price before importing.

All 20 VRT Bands for 2026 (WLTP)

The following table shows the complete VRT band structure for 2026 based on WLTP CO2 emissions. Rates apply to petrol, hybrid, and alternative fuel vehicles unless otherwise noted. Diesel vehicles attract higher rates in the upper bands due to the additional NOx levy.

The NOx levy is additional to these rates and applies to diesel vehicles based on their mg/km NOx output. See the NOx levy section below for full details.

For a detailed breakdown of rates across all vehicle types, visit our Complete VRT Rates 2026 Table.

The NOx Levy Explained

The NOx (nitrogen oxides) levy was introduced in 2021 as an additional charge on diesel vehicles and certain other vehicles with higher NOx emissions. It reflects Ireland’s commitment to improving air quality and reducing harmful pollutants.

The levy is calculated based on the vehicle’s NOx emissions measured in milligrams per kilometre (mg/km). The rates are structured in tiers:

• 0–40 mg/km: €0 (no levy — typically Euro 6d and newer diesel vehicles)
• 41–80 mg/km: €2,500
• 81–120 mg/km: €3,500
• Over 120 mg/km: €4,500

Most modern diesel vehicles manufactured from 2017 onwards meet Euro 6d standards and emit under 40 mg/km of NOx, meaning they attract no NOx levy. However, older diesel vehicles, particularly those meeting Euro 5 or earlier standards, can attract significant additional charges.

The NOx levy only applies to diesel vehicles. Petrol, hybrid, and electric vehicles do not attract this charge, regardless of their NOx output. This makes diesel vehicles with higher NOx output potentially much more expensive to register than their petrol equivalents.

Use our NOx Calculator to check the NOx levy for your specific vehicle.

Step-by-Step VRT Calculation Process

Follow these steps to calculate your VRT liability:

Step 1: Determine the OMSP. Use Revenue’s vehicle valuation data, our OMSP Calculator, or request a dealer quotation. The OMSP is the retail value of the vehicle in Ireland including VAT but excluding VRT.

Step 2: Check CO2 emissions. Find the vehicle’s CO2 emissions figure from the V5C registration document, the Certificate of Conformity, or the vehicle’s spec sheet. Ensure you use WLTP figures for vehicles registered after 2021.

Step 3: Identify the VRT band. Match the CO2 emissions figure to the appropriate band in the 20-band table above.

Step 4: Calculate base VRT. Multiply the OMSP by the band percentage. For example: €25,000 × 30% = €7,500.

Step 5: Add the NOx levy (if applicable). If the vehicle is diesel, check its NOx output and add the appropriate levy amount.

Step 6: Apply any reliefs. Check if the vehicle qualifies for EV relief, disabled driver exemption, or other reliefs. Subtract the relief amount from the calculated VRT.

Step 7: Account for age depreciation. If the vehicle is over two years old, Revenue will apply age-related depreciation to the OMSP before calculating VRT.

For a quick estimate, use our VRT Calculator which automates all these steps.

Common Mistakes to Avoid

• Using UK price instead of Irish OMSP: The OMSP must reflect the Irish market, not the UK purchase price. Irish prices include 23% VAT and dealer margins.
• Ignoring the NOx levy: Many importers forget to factor in the NOx levy for diesel vehicles, which can add €2,500–€4,500 to the total.
• Using NEDC figures instead of WLTP: For vehicles registered after 2021, WLTP CO2 figures are used. NEDC and WLTP figures can differ significantly.
• Missing the 30-day deadline: You must register and pay VRT within 30 days of importing the vehicle. Late registration incurs penalties.
• Assuming the purchase price equals OMSP: A vehicle bought cheaply abroad may still have a high Irish OMSP, resulting in higher VRT than expected.
• Not checking eligibility for reliefs: Many importers miss out on EV relief, transfer of residence relief, or other exemptions they qualify for.
• Forgetting customs duties: For UK imports post-Brexit, customs duty (6.5% for cars) and import VAT (23%) apply in addition to VRT.
• Not budgeting for total cost: VRT is only one component. Budget for customs duty, import VAT, VRT, NCTS fees, and Irish registration costs.

Tips to Reduce Your VRT

• Choose a low-emission vehicle: Vehicles in Bands 1–4 attract significantly lower VRT rates. Look for models with CO2 under 100g/km.
• Consider an electric vehicle: EVs in Band 1 attract 0% base VRT plus up to €5,000 additional relief for vehicles with OMSP under €40,000.
• Avoid high-NOx diesels: Older diesels with high NOx output can attract €3,500–€4,500 in additional levy.
• Buy a vehicle with a lower OMSP: Since VRT is a percentage of OMSP, a lower-valued vehicle means lower tax.
• Consider vehicles over 5 years old: Age depreciation reduces the OMSP used for calculation.
• Import from EU countries: EU imports avoid customs duty (6.5%), saving significant costs compared to UK imports.
• Time your purchase: Vehicle prices can fluctuate. Buy when OMSP values are lower to reduce VRT.
• Check for transfer of residence relief: If you are moving to Ireland, you may qualify for significant VRT relief on your existing vehicle.

See our VRT Exemptions Complete Guide for all available reliefs.

VRT Exemptions and Reliefs

Several exemptions and reliefs can reduce or eliminate your VRT liability:

• Electric Vehicle Relief: Up to €5,000 off VRT for battery electric vehicles with OMSP up to €40,000. Tapered relief between €40,001–€50,000.
• Disabled Driver / Disabled Passenger: Full VRT exemption for vehicles permanently adapted for use by a person with a disability. Requires a primary medical certificate.
• Transfer of Residence: For people relocating to Ireland with their personal vehicle. Vehicle must have been owned and used abroad for at least 6 months.
• Historic Vehicle: Flat €200 VRT rate for vehicles over 30 years old and of historical interest.
• Diplomatic Exemption: Full exemption for vehicles belonging to diplomatic missions and international organisations.
• Charitable Organisation Relief: For vehicles used by approved charitable organisations.
• Emergency Services: Fire, ambulance, and Garda vehicles are exempt from VRT.

Full details on eligibility and application processes are in our VRT Exemptions Complete Guide.

The NCTS Registration Process

After importing your vehicle, you must register it at a National Car Testing Service (NCTS) centre. Here is the process:

Step 1: Book an appointment. Visit the NCTS website or call to book a VRT appointment. You have 30 days from the date of import to complete registration.

Step 2: Gather your documents. Bring the following: foreign registration document (V5C for UK vehicles, equivalent for other countries), bill of sale or invoice, proof of ID, proof of address, and any supporting documents for reliefs.

Step 3: Attend the NCTS centre. A Revenue official will inspect the vehicle, verify the details against the documentation, and determine the OMSP.

Step 4: Pay VRT. Once the assessment is complete, you must pay the VRT amount. Payment can be made by card at the NCTS centre.

Step 5: Receive Irish registration. After payment, you will receive an Irish registration number and a new Irish registration certificate.

Frequently Asked Questions

What is VRT in Ireland?

Vehicle Registration Tax (VRT) is a compulsory one-time tax paid before any vehicle can be registered and driven on Irish roads. It is collected by Revenue and based on the vehicle Open Market Selling Price (OMSP), CO2 emissions, and NOx output for diesel vehicles.

How is VRT calculated?

VRT is calculated by applying a percentage rate (based on CO2 emissions band) to the vehicle Open Market Selling Price (OMSP). For diesel vehicles, a NOx levy may also apply. The OMSP is determined by Revenue using market data.

What are the VRT bands for 2026?

Ireland uses 20 VRT bands based on CO2 emissions measured under WLTP. Band 1 (0g/km) has a 0% rate while Band 20 (over 225g/km) has a 41% rate for petrol/hybrid and up to 51% for diesel when including the NOx levy.

How can I reduce my VRT?

You can reduce VRT by choosing a lower-emission vehicle, purchasing an electric vehicle (up to €5,000 relief), applying for disabled driver exemption, using transfer of residence relief, or selecting a vehicle with an OMSP below the higher tax thresholds.

Do I need to pay VRT on an electric car?

Electric vehicles with an OMSP up to €40,000 qualify for up to €5,000 VRT relief. Between €40,001 and €50,000, the relief tapers. Over €50,000, no relief applies. The base VRT rate for EVs in Band 1 is 0%.

When must VRT be paid?

VRT must be paid before you can register your vehicle. For imports, you have 30 days from the date of import to register and pay VRT at an NCTS centre. Failure to pay results in penalties and the vehicle cannot be legally driven.

What is the NOx levy?

The NOx (nitrogen oxides) levy is an additional charge applied to diesel and certain other vehicles based on their NOx emissions in mg/km. It is added to the VRT amount and ranges from €0 to over €4,000 depending on emissions levels.

Can I appeal a VRT decision?

Yes. If you disagree with Revenue’s VRT assessment, you can appeal to the Commissioner for Income Tax and CAT within 30 days. You must provide supporting evidence such as market valuations or dealer quotes. See our VRT Appeal Complete Guide for details.
