Why a Make/Model/Year Calculator (and Not Just Reg-Based)
Most VRT calculators online require a UK or NI registration plate. That's fine once you have a specific car in mind — useless when you're at the early stages: comparing options, watching auctions, deciding whether to import a Honda Civic 2018 or a VW Golf 2019, asking whether a Japanese auction find is worth the shipping cost.
Our calculator works without a plate. The dropdowns are populated from Revenue's valuations database (25,000+ vehicle codes). Once you hit a valid combination, the matching statistical code is locked in along with the OMSP for a typical clean example of that model — exactly the figure Revenue applies when a real instance of that car comes up for registration.
Use it to shortlist before you shop, not after.
Why the Country of Import Matters
VRT is the same tax regardless of where the car comes from, but the surrounding charges are not. Selecting the country in our calculator triggers the right combination:
- UK (GB) → VRT + 23% Irish VAT + 10% customs duty. The full landed cost is significantly higher than the VRT alone.
- Northern Ireland → VRT only, if the vehicle qualifies under the post-Brexit Windsor Framework (genuinely registered and used in NI before sale, with proof). No customs duty, VAT treatment depends on the vehicle's history.
- Japan → VRT + 10% customs duty + 23% VAT. Add shipping and pre-shipping inspection fees on top.
- EU member states → VRT only for vehicles already registered elsewhere in the EU. Specific rules apply for "new means of transport": vehicles under 6 months old or under 6,000 km are taxed differently and may attract Irish VAT.
- Rest of world → similar to UK: VRT + customs duty + VAT.
Always run the calculator with the correct country selected. Mixing it up is one of the easiest ways to under-budget by several thousand euro.
How VRT Is Calculated — The Method Behind the Tool
Once the make, model, year and country are locked in, the calculation is mechanical:
The VRT formula
Total VRT = (CO₂ band % × OMSP) + NOx levy
Three inputs drive the result: the OMSP (Open Market Selling Price determined by Revenue), the WLTP CO₂ figure of the vehicle (which fixes the percentage rate), and the NOx emissions in mg/km (which fixes the levy). Everything else flows from those three numbers.
CO₂ component (Category A passenger cars)
Revenue maps WLTP emissions to a percentage of the OMSP across 20 bands. Each band has both a percentage rate and a euro minimum — Revenue applies whichever is greater:
| WLTP CO₂ (g/km) | Rate | Minimum |
|---|---|---|
| 0–50 | 7% | €140 |
| 51–80 | 9% | €180 |
| 81–85 | 9.75% | €195 |
| 86–90 | 10.5% | €210 |
| 91–95 | 11.25% | €225 |
| 96–100 | 12% | €240 |
| 101–105 | 12.75% | €255 |
| 106–110 | 13.5% | €270 |
| 111–115 | 15.25% | €305 |
| 116–120 | 16% | €320 |
| 121–125 | 16.75% | €335 |
| 126–130 | 17.5% | €350 |
| 131–135 | 19.25% | €385 |
| 136–140 | 20% | €400 |
| 141–145 | 21.5% | €430 |
| 146–150 | 25% | €500 |
| 151–155 | 27.5% | €550 |
| 156–170 | 30% | €600 |
| 171–190 | 35% | €700 |
| >190 | 41% | €820 |
NOx levy
Banded scale, applied separately and added:
- 0–40 mg/km: €5/mg
- 41–80 mg/km: €15/mg
- Above 80 mg/km: €25/mg
Worked example — 2018 Honda Civic 1.6 i-DTEC from the UK
Representative WLTP CO₂ for this configuration: 102 g/km. Representative NOx: ~35 mg/km. Illustrative OMSP for a clean, low-mileage example: €14,500.
| Step | Result |
|---|---|
| CO₂ band: 101–105 g/km | 12.75% |
| CO₂ component: 12.75% × €14,500 | €1,848.75 (above the €255 minimum, so this rate applies) |
| NOx levy: 35 × €5 | €175 |
| Total VRT | €2,023.75 |
The OMSP, CO₂ and NOx used here are typical figures for a representative example of the configuration. Revenue's actual OMSP for any specific vehicle is determined at NCTS registration and may vary based on mileage, condition and chargeable enhancements (factory options not standard on the Irish-spec equivalent).
When to Switch to the By-Reg Mode
A make/model/year estimate is excellent for decision-making before purchase. Once you've found a specific car with a UK or NI plate, switching to plate mode improves precision in two specific ways:
-
1
Exact variant detection
Two cars with the same model name can differ by €1,500–€3,000 in VRT depending on engine, transmission and trim. The plate tells the calculator which exact variant you're looking at.
-
2
Real CO₂ and NOx from the V5C
Make/model/year mode uses representative figures for that configuration; the plate gives access to the exact emissions Revenue will use at registration.
If your import is a Japanese or EU vehicle without a UK/NI plate, you'll stay in make/model/year mode through to registration — that's expected, and the figure remains highly reliable for any standard configuration.
Common Mistakes That Distort the Estimate
-
1
Wrong country selected
Defaulting to "UK" for an NI import inflates your budget by 10% in fictional customs duty you'll never actually pay.
-
2
Old engine variant chosen
Manufacturers produce multiple 1.6 diesel variants across years. Wrong one selected → wrong CO₂ → wrong band → wrong VRT.
-
3
NEDC values entered manually
If you're overriding our defaults with figures from a pre-2018 spec sheet, those are NEDC. Revenue applies a published conversion at registration: for diesels, (NEDC × 1.1405) + 12.858.

Forgetting that the calculator returns VRT only
For UK, Japan and rest-of-world imports, add VAT and customs duty separately to get the full landed cost. Our country selector flags which apply.
Frequently Asked Questions
How accurate is the make/model/year estimate vs the final NCTS figure?
For standard configurations, expect ±5–10% on VRT. Variance comes from chargeable enhancements, mileage adjustments and exact variant detection. The vast majority of importers fall inside that range.
What if my model doesn't appear in the dropdown?
The vehicle is excluded from Revenue's online database — usually a motor caravan, classic 30+ years old, kit car, low-volume prestige marque, or large commercial. Contact Revenue's Central Vehicle Office for a manual valuation, or submit Revenue's Form VRT Estimate (PDF) before you commit to purchase.
Is the calculator updated for 2026 rates?
Yes. CO₂ bands current since 1 January 2022, NOx schedule current at April 2026. Revenue revises bands at each Finance Act — we update within 24 hours of publication.
Why do some bands show a euro minimum higher than the percentage?
Revenue applies whichever is greater between the percentage and the minimum. For very low OMSPs, the minimum kicks in to prevent VRT bills smaller than €140–€820 depending on the band.
Is this calculator free?
Yes. No signup, no payment, no email harvesting.
Can I save my calculation or compare two cars?
Yes. Each estimate has a shareable link. Use it to compare two configurations, share with a friend, or save before walking into an auction.
Does the figure include motor tax?
No. VRT is a one-off registration tax. Motor tax is a separate annual charge based on the vehicle's CO₂ band — the same band that drives your VRT here. After registration, apply via RF100 and motortax.ie.
Can I appeal the OMSP if Revenue's figure at NCTS is higher than yours?
Yes. After paying the VRT calculated at registration, submit an appeal to Revenue with comparable Irish market evidence (private sale ads, dealer listings of similar vehicles). Unresolved appeals can be escalated to the Tax Appeals Commission.
Will Revenue accept the printout from this calculator at NCTS?
No online estimate is binding. Revenue confirms the final figure only at physical inspection. The calculator exists for budgeting and the buy/walk-away decision before purchase.
