VRT Ireland 2026: How to Calculate and Pay Vehicle Registration Tax When Importing a UK Car

Importing a used car from the UK to Ireland in 2026 means paying Vehicle Registration Tax (VRT) — a tax unique to Ireland that can add thousands to the cost of a UK car. This guide explains exactly how VRT is calculated, what the OMSP is, how to use the Revenue VRT estimator, and how to work out if an import is actually worth it.

The short answer

VRT is charged when you first register a foreign vehicle in Ireland. The rate ranges from 7% to 41% of the car's OMSP (Open Market Selling Price — Revenue's own valuation, not what you paid). For most popular used cars, VRT adds €1,500–€6,000 to the purchase price. You also pay NOx levy (€5–€600) and must complete registration within 30 days of the car arriving in Ireland. Use the Revenue VRT estimator on revenue.ie before buying any UK car.

What is VRT?

Vehicle Registration Tax is a tax charged by Revenue (the Irish tax authority) on the first registration of a vehicle in Ireland. It applies to:

• Cars imported from the UK (including Northern Ireland for some categories)
• Cars imported from any EU country if not previously registered in Ireland
• New cars purchased in Ireland (built into the price by the dealer)

VRT does not apply to cars already registered in the Republic of Ireland. If you buy a used car from an Irish dealer with Irish plates (e.g. 191-D-12345), VRT has already been paid. It only applies once — when the car is first registered.

How is VRT calculated?

The VRT formula has three components:

1. OMSP — Open Market Selling Price

Revenue assesses their own valuation of the vehicle called the OMSP — what they believe the car would sell for on the Irish retail market. The OMSP is NOT the price you paid in the UK. Revenue uses data from Irish market listings, dealer prices, and import statistics to set the OMSP independently.

This matters because: even if you got a bargain on a UK car, Revenue will charge VRT based on the Irish retail value, not your purchase price. A car that cost £8,000 in the UK might have an OMSP of €14,000 in Ireland — and VRT will be calculated on €14,000.

2. CO₂ emissions rate

The VRT rate (as a percentage of OMSP) depends on the car's CO₂ emissions. Rates for 2026:

Note: CO₂ rates are reviewed in each Budget. The rates above are current for 2026 — always verify on revenue.ie before completing any purchase.

3. NOx levy

A separate levy based on the car's nitrogen oxide emissions (measured in mg/km). This is additional to the CO₂-based VRT and typically adds €5–€600 depending on the engine type. Diesels typically pay more NOx levy than petrols at the same output. Electric cars pay the minimum NOx levy (€5).

How to estimate your VRT before buying

Revenue provides a free VRT estimator at revenue.ie/en/importing-vehicles/vrt/index.aspx. To use it you need:

• The car's VIN (Vehicle Identification Number) — 17 characters, found on the dashboard and door jamb
• The car's mileage
• The month and year of first registration

The estimator checks Revenue's own database and returns the OMSP and an estimated VRT liability. This is the most reliable pre-purchase check available. Run it before making any offer on a UK car.

The Autoza VRT Calculator at autoza.ie/vrt-calculator also provides estimates using Revenue's OMSP data.

A worked example: importing a 2021 Volkswagen Golf

Say you find a 2021 VW Golf 1.5 TSI Life in the UK for £12,500 (approximately €14,600 at current exchange rates).

• Revenue OMSP for a 2021 Golf 1.5 TSI in Ireland: €22,500 (hypothetical — check revenue.ie for the actual figure)
• CO₂ emissions: ~128 g/km → VRT rate: 16%
• VRT: 16% × €22,500 = €3,600
• NOx levy (typical petrol): €200
• Total VRT + NOx: €3,800
• Vehicle conversion (right-hand drive to left-hand drive is NOT required in Ireland — Ireland drives on the left, same as the UK)

Total effective cost: €14,600 (car) + €3,800 (VRT + NOx) = €18,400. Compare this to buying an equivalent Irish-market 2021 Golf directly.

The 30-day rule

Once your imported car arrives in Ireland, you have 30 days to complete VRT registration. Driving an unregistered foreign-plated car after 30 days is a legal offence and Revenue enforcement does check. The 30-day period begins from the date the car enters the state, not the date of purchase.

To register:

1. Book an appointment at an NCTS centre (ncts.ie) — the same centres that do NCT tests
2. Bring the vehicle, the foreign registration certificate (V5C for UK), proof of purchase, and your PPSN
3. Revenue assesses the car, confirms the OMSP, and issues a VRT liability
4. Pay the VRT (bank transfer or debit card)
5. Receive your Irish registration plates and log book

When does a UK import NOT make financial sense?

UK imports make sense when: the saving on purchase price (accounting for exchange rate) exceeds the VRT liability plus shipping/logistics costs. They typically do NOT make sense for:

• High-emission cars: Band F/G cars (SUVs, performance cars with 191+ g/km CO₂) face 32–41% VRT — the levy alone can exceed €6,000–€10,000
• Cars with low Irish OMSP: If the Irish market price is already similar to the UK price, there is no saving to offset VRT
• Cars needing NCT: If the imported car requires immediate NCT and repair work, factor those costs in too
• Northern Ireland vehicles (post-Brexit): Check the specific VRT rules for Northern Ireland-registered vehicles — these changed post-Brexit and some categories have specific exemption criteria

What about importing from Northern Ireland?

Northern Ireland occupies a unique position post-Brexit. For VRT purposes, vehicles registered in Northern Ireland are generally treated differently from Great Britain vehicles. Revenue provides specific guidance at revenue.ie for Northern Ireland imports — always verify the current rules as they have been subject to updates since 2021.

Importing an electric car from the UK

EVs benefit from the lowest VRT band (7% for 0 g/km CO₂) and the minimum NOx levy (€5). This can make UK EV imports financially attractive — a UK EV with a £5,000 saving over the Irish price might only attract €1,500–€2,000 in VRT. However, also factor in: whether the SEAI ZECP grant applies to an imported used EV (it does, subject to eligibility conditions — check seai.ie for current terms), and whether the UK battery warranty transfers to an Irish owner.

Quick checklist before importing a UK car

• Run the Revenue VRT estimator (revenue.ie) using the VIN — before making any offer
• Check the exchange rate — a 5% move in GBP/EUR changes your real cost significantly
• Check the UK car has valid MOT and service history (UK equivalent of NCT)
• Run a UK history check (HPI or similar) — check for outstanding finance, write-offs, mileage discrepancy
• Factor in transport/ferry costs if collecting from UK (€200–€600 depending on method)
• Book NCTS appointment before the car arrives — centres get busy, and you have 30 days
• Budget for an Irish pre-purchase inspection if buying sight-unseen
