VRT Budget 2026 — Complete Changes Guide

Budget 2026 brought some of the most significant changes to Ireland's Vehicle Registration Tax system in recent years. If you're planning to import a car in 2026, understanding these changes could save you thousands of euro. From updated CO2 bands to revised NOx levy thresholds, the government has reshaped the VRT landscape to push buyers further toward low-emission vehicles while penalising high polluters more heavily than ever.

This guide covers every VRT-related change announced in Budget 2026, what it means for importers, and how to calculate your costs under the new rules. Whether you're eyeing an electric vehicle, a petrol hybrid, or a diesel, the numbers have shifted and you need to know where you stand before you buy.

Budget 2026 VRT Overview

Budget 2026 delivered on several fronts for the VRT system. The headline changes include an increase in the top CO2 VRT band rate from 41% to 43%, adjustments to the NOx levy thresholds that make older diesels more expensive to register, and a one-year extension of the electric vehicle VRT relief through December 2026. The government also confirmed that the OMSP (Open Market Selling Price) methodology has been refined to incorporate more real-time market data.

Here are the key changes at a glance:

• Top CO2 band rate increased from 41% to 43% for vehicles emitting over 190g/km
• NOx levy thresholds tightened — the zero-levy threshold raised to 80mg/km, higher penalties for emitters above 120mg/km
• EV VRT relief extended through 2026, with up to EUR 5,000 relief for vehicles with OMSP under EUR 40,000
• OMSP calculation updated with expanded data sources for more accurate used car valuations
• Motor tax rates adjusted in line with inflation across all bands
• Enforcement tightened with more ANPR cameras and roadside checks

The overall direction is clear: the government wants you driving cleaner vehicles and is using the VRT system as the primary lever to make that happen. If your car choice aligns with the environmental targets, you'll pay less. If it doesn't, expect to pay more than you would have in 2025.

VRT Band Changes 2026

The CO2 emission bands remain the backbone of the VRT system. Your car's official CO2 figure determines which band it falls into, and that band sets the VRT rate as a percentage of the vehicle's OMSP. For 2026, the bands themselves haven't changed, but the rates at the top end have.

The most significant change is to Band M, which covers vehicles emitting over 190g/km of CO2. The rate has increased from 41% to 43%. On a car with an OMSP of EUR 50,000, that's an extra EUR 1,000 in VRT alone. For high-performance SUVs and luxury vehicles that regularly exceed 190g/km, the total VRT bill can now exceed EUR 25,000.

The lower and middle bands remain unchanged for 2026. Vehicles in Band A1 (0 to 50g/km) still attract just 7% VRT, making them the most tax-efficient choice. The middle bands from A2 through L sit at their 2025 rates, providing stability for buyers of mainstream petrol and hybrid vehicles.

What this means in practice: if you're buying a car with emissions between 131 and 190g/km, your VRT rate is exactly the same as last year. The pain is concentrated at the very top. The government is sending a clear message that the highest-emission vehicles should attract the highest tax burden, and that message has gotten louder with the jump to 43%.

NOx Levy Updates

The NOx levy is where the 2026 Budget hit diesel importers hardest. The nitrogen oxide levy applies exclusively to diesel vehicles and is calculated based on the car's NOx emissions in milligrams per kilometre. For 2026, the thresholds have been recalibrated to penalise older diesels more aggressively.

The updated NOx levy structure for 2026 is:

• Below 80mg/km: No levy applies (threshold increased from the previous year)
• 80 to 120mg/km: Reduced levy rate
• 120 to 180mg/km: Increased levy rate compared to 2025
• Above 180mg/km: Maximum levy of up to EUR 4,850

The raised zero-levy threshold to 80mg/km is a small bit of good news for owners of the very latest Euro 6d diesels, which often achieve NOx emissions well below this level. But for anyone importing a diesel from 2018 to 2020, the increased rates in the middle and upper bands are a significant cost increase.

To put this in perspective: a 2019 BMW 3 Series diesel with NOx emissions around 150mg/km could attract a NOx levy of approximately EUR 2,500 to EUR 3,000 on top of the standard VRT. A 2021 model with emissions below 80mg/km would attract zero NOx levy. That difference alone can swing a buying decision.

If you're considering a diesel import in 2026, the NOx figure should be the first thing you check. Look it up in the vehicle's Certificate of Conformity or the manufacturer's technical specifications before you commit to a purchase. The NOx levy can add thousands to your total cost, and it's often the part of the calculation that catches people off guard.

Electric Vehicle VRT Relief 2026

The government confirmed that the VRT relief for battery electric vehicles will continue through 2026. This is the single biggest financial incentive for importing an EV, and it makes electric vehicles the most tax-efficient choice by a wide margin.

Under the 2026 rules, pure electric vehicles (not plug-in hybrids) qualify for VRT relief as follows:

• EVs with an OMSP up to EUR 40,000: up to EUR 5,000 relief on VRT
• EVs with an OMSP between EUR 40,000 and EUR 50,000: tapering relief
• EVs with an OMSP over EUR 50,000: limited relief on the first EUR 40,000 of value

For most mainstream EVs, this means zero VRT. A 2023 Nissan Leaf with an OMSP of EUR 25,000 has a base VRT of EUR 1,750 at 7%. The EUR 5,000 relief wipes that out entirely. A 2024 Volkswagen ID.4 at EUR 38,000 OMSP would have VRT of EUR 2,660 before relief, also reduced to zero. The sweet spot for EV imports is vehicles with an OMSP under EUR 40,000, where the relief fully covers the tax.

Above EUR 40,000, the relief begins to taper. A Tesla Model 3 Long Range with an OMSP of EUR 55,000 would have VRT of EUR 3,850 at 7%. The relief would reduce this but not eliminate it. Luxury EVs from Porsche, BMW, and Mercedes still attract meaningful VRT even with the relief applied.

The critical point: this relief is not permanent. It has been extended on a year-by-year basis, and the government has signalled that it will be phased out as EV adoption increases. If you're thinking about importing an EV, 2026 may be the last full year to benefit from the current relief levels. Waiting until 2027 could mean a significantly higher tax bill.

OMSP Changes

The Open Market Selling Price is Revenue's estimate of what your car would sell for on the Irish market. When you book your VRT inspection, you will visit an NCTS (National Car Testing Service) centre, where they verify your vehicle's details before registration. It is the foundation of every VRT calculation, and for 2026, Revenue has updated how it determines OMSPs for used imports.

The key change is that Revenue is now drawing on a wider range of data sources. In previous years, OMSP assessments relied heavily on a limited set of dealer listings and historical data. For 2026, Revenue has integrated auction results, real-time dealer listings, and cross-referenced import data to produce more accurate and current valuations.

In practice, this means OMSPs have shifted in both directions. Popular models that hold their value well, such as the Toyota RAV4, Hyundai Tucson, and Nissan Qashqai, have seen OMSPs increase because the data now reflects their actual market value more closely. Less popular models, particularly older luxury sedans and niche imports, have seen stable or reduced OMSPs because the expanded data shows lower demand.

Revenue has also tightened the evidence standards for challenging an OMSP assessment. Dealer listings within the last 30 days are preferred over private sale advertisements. If you believe Revenue's OMSP is too high, you now need to provide current, comparable listings from Irish dealers to support your case. Generic UK advertisements or outdated listings carry less weight than they used to.

For importers, the practical advice is simple: check the OMSP before you buy, not after. Use our calculator to estimate what Revenue is likely to value your car at, and factor that into your total cost calculation. A car that looks like a bargain at the UK purchase price might not be such a good deal once the Irish OMSP pushes the VRT higher than expected.

What This Means for Importers

For anyone planning to import a car to Ireland in 2026, the Budget changes create both opportunities and risks. The overall message is that choosing the right vehicle matters more than ever, and the financial gap between clean and dirty vehicles has widened.

Electric vehicle importers are in the strongest position. The 7% VRT rate combined with up to EUR 5,000 of relief and minimal motor tax of EUR 120 per year makes EVs the cheapest vehicles to register and own from a tax perspective. If you can find an EV with an OMSP under EUR 40,000, you're looking at potentially zero VRT.

Petrol and hybrid importers face stable conditions. The CO2 bands haven't changed for these vehicles, so the VRT calculation is predictable. The key is choosing a car in a lower CO2 band. Vehicles under 140g/km fall into the 20% VRT band or lower, which keeps the tax manageable on most mainstream cars.

Diesel importers face the toughest environment. The NOx levy adds a significant premium on top of the regular VRT, and the increased rates in 2026 make older diesels particularly expensive. Unless you're doing very high annual mileage, the total cost of owning a diesel import is now higher than petrol, hybrid, or electric alternatives for most buyers.

UK imports continue to attract a 10% customs duty on cars that don't meet rules of origin requirements. Combined with 23% VAT on the total value and the VRT itself, importing from the UK requires careful cost modelling to make sure the car is still affordable after all taxes are applied.

2025 vs 2026 Comparison Table

Element	2025	2026
Top CO2 band rate (190+ g/km)	41%	43%
EV VRT relief	Up to EUR 5,000	Up to EUR 5,000 (extended)
EV VRT rate (Band A1)	7%	7% (unchanged)
NOx zero-levy threshold	Below 60mg/km	Below 80mg/km
NOx maximum levy	Up to EUR 4,850	Up to EUR 4,850
NOx mid-range levy (120-180mg/km)	Moderate	Increased
OMSP methodology	Limited data sources	Expanded data sources
EV motor tax	EUR 120/year	EUR 120/year (unchanged)
Customs duty (UK non-origin)	10%	10% (unchanged)
Top motor tax band	EUR 2,350/year	EUR 2,350/year (unchanged)

The changes are targeted rather than sweeping. The government hasn't overhauled the system but has instead nudged the numbers in the direction they've been heading for years: more expensive for high emissions, more affordable for low emissions. The biggest single change is the 43% top rate, which affects a relatively small number of vehicles but sends a strong signal about the direction of policy.

How to Calculate Your VRT Under New Rules

Calculating your VRT under the 2026 rules follows the same basic process as before, but with the updated rates applied. Here's a step-by-step walkthrough:

1. Find the OMSP. This is what Revenue thinks your car is worth in Ireland. You can estimate this using our calculator, or check Revenue's guidelines for the specific make, model, and year. The OMSP is the starting point for everything.
2. Identify the CO2 band. Look up your car's official CO2 emissions figure (WLTP if available, NEDC if not) and find which band it falls into. This determines the base VRT rate as a percentage of OMSP.
3. Calculate base VRT. Multiply the OMSP by the CO2 band percentage. For example, a car with an OMSP of EUR 30,000 in Band C (20%) would have a base VRT of EUR 6,000.
4. Apply EV relief if applicable. If you're importing a pure electric vehicle, subtract the applicable relief amount from the base VRT. The relief can reduce your VRT to zero for vehicles with an OMSP under EUR 40,000.
5. Add the NOx levy if applicable. If your car is diesel, look up its NOx emissions figure and calculate the levy based on the 2026 thresholds. Add this to the base VRT.
6. Add customs duty if importing from the UK. Non-qualifying UK imports attract a 10% customs duty on the vehicle value. This is separate from VRT but adds to your total cost.
7. Add VAT. VAT at 23% is charged on the total of the vehicle value plus customs duty (if applicable). This is separate from VRT.

The simplest way to get an estimate is to use our VRT calculator, which has been updated for all 2026 rates and thresholds. Enter your vehicle details and you'll get a ballpark figure within two minutes. Remember that the calculator provides an estimate — the actual VRT will depend on Revenue's OMSP assessment at the time of your appointment.
