Vehicle Registration Tax (VRT) is a one-time tax paid when registering any imported vehicle in Ireland for the first time. For Japanese imports, it is almost always the single largest tax bigger than customs duty, sometimes bigger than the shipping cost itself.
Many first-time buyers underestimate VRT by €1,000–€3,000. The reason is almost always the same: they calculate based on what they paid in Japan, not on how Revenue values the car in Ireland.
At Nobuko Japan, we have guided over 100 Irish buyers through the Japanese import process from Tokyo auction to Irish plates. This guide gives you the exact formula Revenue uses, with real 2026 numbers, so there are no surprises at the NCTS centre.
VRT on a Japanese import = OMSP × COâ‚‚ rate (7%–41%) + NOx levy. OMSP is Revenue's estimate of Irish market value not your Japanese purchase price.
For Category A passenger cars, Revenue uses this formula:
VRT = OMSP × CO₂ Rate (%) + NOx Levy
Three components. Let's break each one down.
OMSP stands for Open Market Selling Price. It is defined by Revenue as the price a vehicle could reasonably be expected to fetch if sold on the Irish market.
Revenue does not use your Japanese auction price. They look at comparable models on the Irish used car market DoneDeal, CarZone, dealer stock and assign a value based on that.
Example: You buy a 2017 Toyota Voxy at a Japanese auction for €4,500. Revenue checks Irish listings for the same model, year, and mileage. They find prices of €9,000–€11,000 and assign an OMSP of €10,000. You pay VRT on €10,000 not on €4,500.
Why Revenue does this: VRT is designed to tax the Irish market value, not an overseas purchase price. This protects the domestic used car market and ensures tax parity with Irish-registered vehicles.
Nobuko Japan tip: Before bidding on any car, search DoneDeal and CarZone for the same make, model, year, and approximate mileage. That is your best OMSP estimate before you commit.
Once OMSP is established, Revenue applies a percentage based on the vehicle's COâ‚‚ emissions. This is the 2026 rate table for Category A passenger cars:
| COâ‚‚ Emissions (g/km) | VRT Rate | Minimum Charge |
| 0–50 (EV/PHEV) | 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 | 23% | €460 |
| 151–155 | 25.5% | €510 |
| 156–170 | 28% | €560 |
| 171–190 | 34% | €680 |
| 191+ | 41% | €820 |

The "whichever is greater" rule: You always pay the higher of (a) OMSP × rate or (b) the minimum charge for that band.
Example: Car with OMSP €5,000, CO₂ 120 g/km (16% rate). 16% × €5,000 = €800. Minimum charge = €320. You pay €800.
Why this matters for Japanese imports: Most popular JDM models Toyota Voxy, Toyota Alphard, Honda Odyssey, Nissan Elgrand fall in the 96–130 g/km range, meaning VRT rates of 12%–17.5%. Hybrids like the Toyota Prius and Toyota Aqua fall in lower bands (51–95 g/km), which is why they are the most cost-efficient Japanese imports into Ireland.
Since 1 January 2020, Revenue applies a NOx (nitrogen oxide) levy on top of the COâ‚‚-based VRT. This primarily affects diesel vehicles but can also apply to some petrol and hybrid engines.
How the NOx levy is calculated:
| NOx Emissions (mg/km) | Rate |
| 0–60 mg/km | €5 per mg/km |
| 61–80 mg/km | €5 for first 60 mg + €15 per mg for next 20 |
| 81+ mg/km | €5 for first 60 + €15 for 61–80 + €25 per mg for remainder |
Maximum caps:
Example diesel car at 120 mg/km:
Critical for Japanese imports: Japanese vehicles do not carry European Certificates of Conformity (CoC). Revenue accepts NOx documentation from the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT). Without it, Revenue applies a flat default charge almost always higher than your actual emissions would generate.
Nobuko Japan provides official Japanese emissions documentation with every shipment. You arrive at the NCTS centre fully prepared.
Vehicle: 2017 Toyota Voxy (petrol hybrid) Japanese auction price: €4,500 Estimated Irish OMSP: €10,000 CO₂ emissions: 110 g/km NOx emissions: ~20 mg/km (petrol hybrid)
Step 1 VRT rate from COâ‚‚: 110 g/km falls in the 106–110 band → 13.5% rate
Step 2 Base VRT: €10,000 × 13.5% = €1,350 Minimum charge for this band: €270 €1,350 > €270 Base VRT = €1,350
Step 3 NOx levy: 20 mg/km × €5 = €100 (well below the €600 cap)
Step 4 Total VRT: €1,350 + €100 = €1,450
This is paid at the NCTS centre before Irish plates are issued.
A Nobuko Japan customer imported a 2016 Toyota Estima Diesel from Japan. He used a third-party online calculator and budgeted €1,800 for VRT.
At the NCTS centre in Dublin, Revenue assigned an OMSP of €16,000. His calculator had assumed €9,000.
He paid the €7,180 under protest, then filed an appeal to the Tax Appeals Commission with evidence: DoneDeal and CarZone listings showing comparable Estima models at €9,000–€11,000.
Result: Revenue reduced the OMSP to €10,500.
The appeal took four months but succeeded. Over 50% of VRT OMSP appeals succeed, according to the Tax Appeals Commission but you must pay first, then claim the refund.
If you disagree with the OMSP: You pay first. Then appeal to Revenue (VRT Appeals, Wexford Revenue District) or escalate to the Tax Appeals Commission. Bring comparable Irish market listings as evidence.
Mistake 1 Calculating VRT on your purchase price. VRT is based on Revenue's OMSP (Irish market value), which is typically 1.5x–3x higher than a Japanese auction price for popular models.
Mistake 2 Arriving without NOx documentation. Diesel imports without official MLIT NOx figures face a Revenue default charge that is almost always higher than the actual rate. Budget an extra €1,000–€3,000 if you arrive unprepared.
Mistake 3 Missing the 30-day registration deadline. You have exactly 30 days from the date of arrival to complete registration. After that, penalties apply. Revenue can also direct the Gardaà to seize an unregistered vehicle.
Mistake 4 Trusting the Revenue online calculator as final. Revenue's own guidance states the online VRT calculator is "for guidance only." The final OMSP is set at the NCTS inspection, and it can differ significantly especially for rare Japanese models with limited Irish comparables.
Mistake 5 Not appealing an inflated OMSP. If Revenue's OMSP is clearly above what similar vehicles sell for in Ireland, appeal it. The process takes 2–4 months, but over half of appeals succeed and refunds are paid.
