Bringing a car back to Galway from the UK, the North or anywhere else outside the State is the easy part. Registering it is where people lose money. Vehicle Registration Tax is not charged at the Motor Tax Office, it is not based on what you paid for the car, and it is not collected at every NCT centre in the county. The National Car Testing Service registers vehicles on Revenue’s behalf, and the process runs on two hard deadlines: an appointment booked within seven days of the vehicle entering the State, and registration completed within thirty days. Irish Revenue The number that decides whether an import is worth doing is the OMSP, Revenue’s own assessment of what your exact vehicle would sell for in Ireland. Work out that figure and your CO₂ band before you hand over any money abroad, using Revenue’s calculator on ros.ie or an independent estimate. A €12,000 car bought in Britain can carry an Irish valuation several thousand euro higher, and the tax follows the Irish figure rather than the invoice.
In short
- Two centres in Co. Galway handle VRT: Galway NCT Centre (Merlin Park) and Ballinasloe NCT Centre. Not every NCT centre registers imports.
- Book within 7 days of entry into the State; register within 30 days.
- Cars (Category A): 7% to 41% of OMSP by CO₂ band, plus a separate NOx levy.
- Battery-electric relief of up to €5,000 applies only to vehicles registered before 31 December 2026.
- No NOx paperwork means the maximum default charge: €4,850 on a diesel.
Where you actually register a vehicle in Galway
Co. Galway has two designated VRT centres. Both appear on Revenue’s official list of registration locations, and both collect the tax on the day of inspection.
| Centre |
Address |
Eircode |
| Galway NCT Centre |
Merlin Commercial Park, Doughiska, Merlin Park |
H91 FNF4 |
| Ballinasloe NCT Centre |
Unit 9, Pollboy Industrial Estate |
H53 NW94 |
The distinction that catches people out: an NCT centre is not automatically a VRT centre. Athlone, the obvious stop for anyone coming from the east, runs roadworthiness testing but does not appear on Revenue’s VRT registration list. If Merlin Park and Ballinasloe are both booked out, the nearest alternatives on that list are Ennis (Co. Clare), Westport (Co. Mayo), Tullamore (Co. Offaly), Carrick-on-Shannon (Co. Leitrim), Sligo and Limerick. You are not obliged to register in your own county, and any designated centre issues the same registration number.
Opening hours differ sharply between the two Galway sites and rotate week to week. In the week beginning 3 September 2026, for instance, Merlin Park ran long weekday hours plus a Saturday morning slot, while Ballinasloe operated a shorter weekday-only schedule. Check the published hours for your specific date rather than assuming.
The two deadlines, and what breaks if you miss them
The clock starts on the day the vehicle enters the State, not the day it reaches Galway and not the day you get around to booking.
- Seven days to book the inspection. The appointment must be made within seven days of the vehicle entering the State, and the registration process completed within thirty days of arrival.
- Thirty days to complete registration. Additional VRT applies where a vehicle is not registered inside thirty days. Driving an unregistered vehicle is an offence: Revenue or the Gardaí can detain it, and a seized vehicle is released only on payment of a penalty.
Booking early matters more in the west than in Dublin, because two centres serving the whole county leave less slack when slots fill. Book the moment the vehicle lands, even if the only available inspection date sits further out.
How the bill is built
Two components, calculated separately and added together.
The CO₂ component is a percentage of OMSP, set by the vehicle’s WLTP CO₂ figure. Category A passenger cars run from 7%, or €140 if greater, at 0 to 50 g/km, up to 41%, or €820 if greater, above 190 g/km, across twenty bands in force since 1 January 2022. Older imports registered on NEDC data are converted using Revenue’s published formulae before a band is assigned.
| Category |
What it covers |
Rate |
| A |
Passenger vehicles including cars and minibuses carrying no more than eight people plus a driver |
7% to 41% of OMSP, plus NOx |
| B |
Goods vehicles up to 3.5 tonnes, and motor caravans |
8% or €160 up to 120 g/km; 13.3% or €266 above |
| C |
Larger commercials, agricultural tractors, buses, and vehicles more than 30 years old at registration |
€200 flat |
| D |
Ambulances, fire engines, road rollers, sweeping machines and refuse carts |
No VRT |
| M |
Motorcycles and e-mopeds |
€2 per cc to 350 cc, €1 per cc thereafter, reduced by age |
Both components have to be worked out on your specific vehicle before you commit to an import, and vrt-calculator.ie applies the current bands and the NOx tiers to a given OMSP without you having to read the schedules. The NOx levy applies on top. It has been charged since 1 January 2020 on every Category A vehicle except full electrics, hybrids included. The first 40 mg/km costs €5 per mg, the next 40 mg/km costs €15 per mg, and everything above 80 mg/km costs €25 per mg.
This is where imports go wrong. Without satisfactory evidence of NOx emissions, Revenue applies a default charge of €4,850 on a diesel and €600 on anything else. Revenue’s own worked example is blunt about the cost: a diesel hatchback with an OMSP of €12,017 pays €2,102 on the CO₂ side, then €4,850 in NOx because no evidence was presented, for a total of €6,952. Get the NOx figure off the Certificate of Conformity or the foreign registration document before you buy.
The electric window closes on 31 December 2026
If you are weighing up an EV import, timing is now the deciding factor. Series-production battery-electric cars and commercials registered before 31 December 2026 qualify for relief of up to €5,000, applied automatically at the NCTS centre with no separate application form. Full relief applies up to an OMSP of €40,000, a reduced level applies between €40,000 and €50,000, and relief has been removed above €50,000. Series-production electric motorcycles and e-mopeds are exempt from VRT over the same period. On a €30,000 EV, Revenue’s own example puts the 7% charge at €2,100, fully absorbed by the relief, leaving nothing to pay.
A Galway buyer considering an electric import in late 2026 is working against a fixed date. The vehicle has to be registered, not merely bought or shipped, before the year ends.
What to have with you at the inspection
Turning up short of paperwork is the most common reason a Galway appointment produces no registration number.
- The foreign registration certificate. Failure to present it leads to registration being refused, and for a UK import the full V5C has to come from the seller.
- Evidence of the date of entry. Shipping details or travel documents will do, and where the invoice is more than 30 days old Revenue may look for evidence that the vehicle was stored outside the State.
- The customs declaration MRN for anything transported from outside the EU. This is required, not optional.
- PPS number and photo ID, such as a passport or driving licence, plus the Certificate of Conformity where you have it.
- Any VRT exemption notification already issued to you by Revenue, for instance under transfer of residence.
The vehicle is examined against the documents, and if the paperwork is missing or the vehicle does not match it, no registration is issued. Once the tax is paid, a registration number issues.
Frequently asked questions
Is a VRT inspection the same as an NCT?
No. A VRT inspection identifies an imported vehicle and charges the tax so it can be registered. An NCT is a periodic roadworthiness test on a vehicle already registered here. Both happen in the same buildings in Galway and Ballinasloe, but they are separate appointments with separate purposes.
Can I drive the car to my appointment before it is registered?
NCTS asks you to carry proof of your confirmed appointment whenever you use the vehicle until the registration process is complete. Beyond that journey, driving an unregistered vehicle is an offence and the car can be detained.
Does VRT cost more or less depending on where I register?
No. OMSP is Revenue’s national valuation of the vehicle itself. Registering in Ballinasloe, Ennis or Dublin produces the same figure. Only the waiting time changes.
Is there a fee for the registration service at the centre?
No separate charge applies for the registration service, and Revenue pays for one appointment only. A second appointment is at the customer’s expense.
What if I need to move my appointment?
Cancelling or rearranging within five working days of the test date, or failing to show up, has consequences for your booking, so reschedule well outside that window.
I am registering a 1994 van. Which category?
Age decides it. A vehicle more than 30 years old at the time of registration falls into Category C and pays €200, whatever its engine, emissions or valuation.
