VRT on an Audi
every model, priced
Last updated June 2026 — written and fact-checked by the VRT Audi editorial team, working from the current Revenue Category A rates and NOx schedule.
Whether you are eyeing an A3, a Q5 TDI or an e-tron, the VRT bill comes down to your car's OMSP, its CO₂ band and — for diesels — a separate NOx levy. Enter your plate or model in the calculator and see the figure before you commit.
Below: how the tax is built, the EV relief that can take a battery-electric Audi to near zero, a full worked Q5 40 TDI quattro example, the import deadline, and an indicative band for every Audi in the range.

How VRT Is Calculated on an Audi
VRT on an Audi in Ireland is the OMSP of the car multiplied by a CO₂-based rate of 7% to 41%, plus a separate NOx levy — so a single Audi can owe anywhere from a few hundred euro to several thousand. It is a one-off tax you pay when you first register a vehicle in Ireland, including any Audi you import. The calculation rests on three inputs set by Revenue, not by you, and a passenger Audi falls under Category A of Revenue's five vehicle categories — which is what fixes the 7%–41% scale that applies to it.
The OMSP Revenue assigns
The Open Market Selling Price is Revenue's own assessed market value for your exact Audi variant in Ireland — drawn from the data.gov.ie VRT dataset, updated quarterly. It is not the price you paid abroad, so a cheap purchase does not automatically mean a low bill.
The CO₂ band (7%–41%)
Category A rates run from 7% to 41% on a WLTP basis, in force since 1 January 2022. The lower your Audi's WLTP CO₂ g/km, the lower the percentage applied to its OMSP. Where only an older NEDC figure exists, Revenue converts it by fuel type first.
The diesel NOx levy
Every diesel Audi TDI pays a separate NOx charge on top of the CO₂ component, banded per milligram per kilometre. It is calculated apart from the CO₂ figure and then added in to give the total VRT.
Where the cleaner and the heavier Audis sit
The cleanest petrol and hybrid Audis sit near the bottom of the scale, while higher-emitting diesel and performance models climb toward the 41% ceiling. Every Audi variant also maps to a depreciation code that pins down the exact model, engine and trim — and therefore the precise OMSP Revenue holds for it. Entering the right specification in the calculator is the difference between a rough guess and an accurate estimate.
The NOx Levy on Diesel Audi TDI Models
The CO₂ component is only half the story for a diesel Audi: the second charge, the NOx levy, is where TDI importers are most often caught out. It is charged per milligram of NOx per kilometre and can add a meaningful sum to the bill.
How the NOx charge is banded
The levy is banded per mg/km, so the more NOx your engine emits, the more you pay. Each band threshold lifts the rate, so an older, higher-NOx diesel TDI can attract a noticeably larger levy than a cleaner, newer one. Two TDIs with similar OMSPs can still diverge by several hundred euro on the NOx line alone, purely because of their certified emissions.
Finding your Audi's NOx figure
Your Audi's official NOx value comes from its Certificate of Conformity (CoC) or the vehicle's emissions data, not from the brochure. For an accurate estimate, take the NOx mg/km figure from the CoC and use it in the calculator; if you cannot find it, Revenue applies a default that is usually less favourable.
Worked Example — 2020 Audi Q5 40 TDI quattro From the UK
A 2020 Audi Q5 40 TDI quattro imported from the UK shows the full picture: an OMSP-based CO₂ component in a higher diesel band, plus a NOx levy, plus customs and VAT because it comes from Great Britain. All figures below are indicative estimates pending confirmation on the official calculator.
Step 1 — OMSP and CO₂ band
Revenue assesses an OMSP for this Q5 40 TDI variant from its dataset — say in the region of €38,000 for illustration. As a diesel SUV, its WLTP CO₂ places it in a higher Category A band, which here we treat as the 23% rate. The exact OMSP and band come from the car's specification.
Step 2 — CO₂ component + NOx levy (Table 1)
Multiply the OMSP by the band rate, then add the NOx levy to reach total VRT. On the indicative figures above:
| OMSP — Revenue assessed | €38,000 |
| CO₂ rate (Cat A, WLTP) — diesel band | 23% |
| CO₂ component — OMSP × rate | €8,740 |
| NOx levy — per mg/km (diesel) | €600 |
| Total VRT — CO₂ component + NOx | €9,340 |
| Customs / VAT — GB import (separate) | See Step 3 |
Table 1 — indicative VRT breakdown, illustrative figures only.
Step 3 — Don't forget customs and VAT
Because this Q5 comes from Great Britain, two further charges land before you ever reach the NCTS — see the import section below for how they work. Budget for them separately from the €9,340 VRT figure above, as neither is included in the VRT calculation.
VRT Relief for Electric Audis: e-tron, Q4 e-tron and Q6 e-tron
If your Audi is electric rather than a diesel TDI, the calculation flips in your favour. EV relief is a defined Revenue scheme, not a loophole — and it is worth knowing exactly which Audis it covers and how far it goes.
Which electric Audis qualify
The eligible models are Audi's battery-electric range — the e-tron / Q8 e-tron, the Q4 e-tron and the Q6 e-tron. Because these are BEVs, they sit outside the diesel NOx charge entirely and pay no NOx levy.
How much the relief is worth
The relief reduces VRT up to a cap tied to OMSP thresholds: below the threshold it can wipe out most or all of the VRT, while higher-OMSP EVs taper toward a smaller benefit. So an electric Audi is a case of relief rather than blanket exemption — a high-value e-tron can still owe a reduced amount once its OMSP clears the threshold. Confirm the current limits before budgeting.
Importing Your Audi: the Deadline, NCTS and Paperwork
You must register an imported Audi at an NCTS centre within 30 days of it entering the State, or you risk penalties and interest on the VRT due. Knowing the cost is only useful if you register on time — and Ireland's import process runs to a strict clock. VRT is payable on the first registration of any new or used vehicle in Ireland.
From purchase to plates
- 1Clear customs first if the Audi is a Great Britain import.
- 2Book your NCTS appointment within the 30-day window.
- 3Attend the inspection so the centre can verify the vehicle and its details.
- 4Pay the VRT calculated at the appointment.
- 5Receive your registration number and fit Irish plates.
Documents you'll need
- Foreign registration certificate (the UK V5C).
- Purchase invoice showing the price and date.
- Certificate of Conformity (CoC) for CO₂ and NOx.
- Photo ID and proof of address in your name.
- Customs clearance proof for GB imports.
Customs and VAT on Great Britain imports
Post-Brexit, a car coming from Great Britain is treated as an import from outside the EU, so customs duty and import VAT can apply on top of VRT. Customs duty is generally charged on the car's value plus shipping, and import VAT is then applied to that combined total — which is why a Great Britain import can cost considerably more than the VRT alone suggests. Vehicles from Northern Ireland are treated differently, so confirm your route before assuming VRT is the only charge.
How the Calculator Works
The tool embedded at the top of this page walks you from a registration plate or model to a full estimate in a few steps. Here is what happens at each stage.
Choose the country of origin
Start the form by selecting where the Audi is coming from — Great Britain, Northern Ireland or another EU state — so the tool knows whether to flag the customs and VAT layer alongside VRT.
Enter the plate or pick the model
Type the foreign registration to decode the exact Audi automatically, or select the model, body type and engine by hand if you are still shopping and don't yet have a plate.
Read the estimate
The tool returns the OMSP, the CO₂ component and the diesel NOx levy, then totals them into an indicative VRT figure for your specific Audi.

Audi VRT FAQ
Practical questions that come up beyond the core calculation, the model table and the import steps above.
Is an Audi cheaper to register than other German marques?
Not because of the badge. VRT is driven by your Audi's OMSP and emissions, not by the manufacturer, so a high-CO₂ Audi can cost more than a cleaner rival and a low-CO₂ Audi can cost less. Comparing like-for-like body types and powertrains matters more than the marque itself.
Does a plug-in hybrid Audi qualify for the same relief as a full e-tron?
No. The OMSP-based VRT relief applies to battery-electric Audis such as the e-tron, Q4 e-tron and Q6 e-tron. A plug-in hybrid TFSI e is taxed on its CO₂ band like any other combustion model and does not access the BEV relief, though its low WLTP CO₂ usually places it in a relatively gentle band.
Will adding factory options to my Audi raise the VRT?
It can. Revenue's OMSP reflects the Irish market value of your exact specification, and factory-fitted extras that were not standard — larger wheels, a panoramic roof, S line trim — can lift the assessed value and, on some models, nudge the CO₂ band upward. Two outwardly similar Audis can therefore carry different VRT.
Is the VRT figure I get the same as my annual motor tax on the Audi?
No — they are two separate charges. VRT is the one-off tax you pay to register the Audi in Ireland. Motor tax is the recurring annual charge, banded on the same WLTP CO₂ figure for cars first registered from 2021. A clean Audi keeps both low; a high-emitting TDI raises both.
Can I drive my imported Audi on UK plates while I wait for the NCTS appointment?
Only inside the registration window. Once the Audi has entered the State you have a limited period to present it for registration, and continued use on foreign plates beyond that exposes you to enforcement and detention of the vehicle. Book your NCTS slot as soon as the car arrives rather than driving on it indefinitely.
Does mileage affect the VRT on my Audi?
Indirectly. VRT is charged on the OMSP, and Revenue's assessed value reflects the typical condition of that Audi variant rather than your specific odometer reading. Very high or very low mileage is one of the grounds you can cite if you later appeal an OMSP you believe is out of line with the market.
Is a left-hand-drive Audi imported from the EU treated the same as a UK one?
The VRT calculation is identical — OMSP times CO₂ rate, plus the NOx levy for diesels. The difference is the import layer: a car coming from another EU member state does not face the customs duty and import VAT that a Great Britain import can attract, so an EU-sourced Audi can land cheaper overall even when the VRT is the same.
How current are the indicative bands shown for each Audi model?
The model table is indicative for 2026 and reflects the Category A CO₂ scale of 7% to 41% in force since January 2022, plus the diesel NOx levy. Because Revenue revises OMSP values on a rolling basis and bands can shift with each Finance Act, treat the table as a guide and confirm your exact figure on the official calculator.
In Summary
Work out your Audi's likely band in the table above, then run your plate or model through the calculator to turn it into a real figure before you buy.
For a diesel TDI, add the NOx levy on top of the CO₂ component and budget customs and VAT separately if the car comes from Great Britain. For a battery-electric e-tron, check the EV relief against the OMSP threshold.
Then book your NCTS appointment inside the registration window, bring the V5C, invoice and CoC, and pay the confirmed VRT on the day.
