I've lost count of how many emails I've gotten from people who bought a car in the UK and then discovered the tax bill was way more than they expected. The conversation usually goes something like: "I paid £10,000 for a car in Birmingham and they want another £6,000 to let me register it in Dublin. How is that legal?"
It's legal because importing a car from the UK to Ireland post-Brexit is a different game than it used to be. Before January 2021, you could drive a car from England to Ireland and pay pretty much just VRT. Now you've got customs duty, import VAT, and VRT all stacked on top of each other. And the rules are different depending on whether the car comes from Great Britain or Northern Ireland, which confuses people even more.
Let me break down exactly how VRT and customs duties work for UK imports, with the numbers you need to budget properly.
The Post-Brexit Reality for UK Car Imports
Before Brexit, the UK was in the EU single market and customs union. Goods moved freely between the UK and Ireland. Cars were no exception. You bought a car in England, drove it to the ferry, brought it to Dublin, paid VRT, and got Irish plates. Simple.
Now, Great Britain is a "third country" from the EU's perspective. That means cars entering Ireland from England, Scotland, or Wales have to go through customs clearance, just like cars from Japan or the USA. Customs duty and import VAT apply. The era of friction-free car imports from GB is over.
Northern Ireland is different, and I'll get to that. But first, let's deal with the main scenario: importing from GB.
Customs Duty on UK Car Imports: The Full Breakdown
When you bring a car from Great Britain to Ireland, the first tax you'll encounter is customs duty. The standard rate for passenger cars (HS code 8703) is 10% of the customs value.
The customs value, also called the CIF value, is calculated as:
Purchase price + Transport costs + Insurance costs
If you buy a car for £10,000 (roughly €11,500 at current rates), pay €350 for ferry transport and €150 for transit insurance, your customs value is €12,000. Customs duty at 10% is €1,200.
There's a potential exception here. If your car was manufactured in the EU or has sufficient EU-origin content, you might qualify for a reduced or zero customs duty rate under the EU-UK Trade and Cooperation Agreement. To claim this, you need a statement of origin from the seller proving the car was made in the EU. In practice, this is rare for used cars. The dealer you bought from in Manchester is unlikely to provide a statement of origin for a second-hand car.
Most used car imports from GB pay the full 10%. Budget for that, and anything less is a bonus.
How VAT Works on UK Car Imports
This is where the numbers get serious. Import VAT at the Irish standard rate of 23% is applied on top of the customs value plus the customs duty. It's a cascading calculation.
Using the example above:
- Customs value: €12,000
- Customs duty (10%): €1,200
- Value for VAT: €13,200
- VAT (23%): €3,036
- Total import taxes so far: €4,236
So on a €11,500 car, you're already paying over €4,200 just to get it through customs. That's before you've even looked at VRT.
A question I get a lot: "Can I avoid paying VAT if I buy the car VAT-qualifying in the UK?" The answer is no. The VAT you're paying here is Irish import VAT, not UK VAT. Even if the car was sold to you without UK VAT (margin scheme or export sale), you still owe Irish import VAT when it enters the country. Revenue doesn't care what VAT arrangement you had with the UK seller. They want their 23% on the import.
There is one situation where you might not pay import VAT: if the car was in free circulation in Northern Ireland before you bought it. I'll cover that in the NI section below.
How to Pay Customs Duty and VAT
You can't just rock up at Dublin Port with cash and expect to pay the taxes on the spot. The customs declaration is done electronically through Revenue's Automated Entry Processing (AES) system or through a customs agent's system.
Here's the typical process:
- Your car arrives at the port (Dublin, Rosslare, Cork)
- You or your customs agent submits an import declaration to Revenue through AES
- Revenue processes the declaration and issues a payment demand
- You pay the customs duty and VAT (usually by bank transfer or card)
- Revenue issues a customs clearance document (SAD or C88)
- The car is released from customs and you can transport it
The whole process usually takes 1 to 3 days if you use a customs agent. If you do it yourself, give it a week, especially if this is your first time. The AES system is not the most intuitive thing in the world.
Most people use a customs agent. The fee is typically €100 to €250, and it's money well spent. They know the HS codes, they know how to fill in the forms, and if something goes wrong, they handle it. I've seen people try to do it themselves and end up with their car stuck at the port for two weeks because they selected the wrong box on the form.
VRT After Customs Clearance: What Happens at the NCTS
Once the car is through customs and you have your clearance documents, the next step is VRT. You need to book an appointment with the National Car Testing Service (NCTS) to register the car and pay VRT.
Here's what happens at the NCTS appointment:
The inspector checks the car's identity against the documents - VIN number, engine number, mileage. They verify the customs clearance document to confirm import taxes were paid. Then Revenue assesses the OMSP (Open Market Selling Price) based on the car's age, mileage, condition, trim level, and specifications. They calculate VRT using the OMSP and the car's CO2 emissions band. You pay the VRT. You get your Irish registration certificate and plates.
The OMSP is the bit that makes people nervous, and rightly so. Revenue's OMSP is not the same as your purchase price. If you bought a car cheap because it had high mileage or needed work, Revenue's OMSP might be higher than what you paid. And VRT is calculated on the OMSP, not your invoice.
Let me give you an example. You buy a 2019 Audi A4 in England for €14,000 because it's got 120,000 km on the clock. Revenue might assess the OMSP at €18,000 based on average market prices for that model year. VRT at, say, 18% (Band C, 145g/km CO2) would be €3,240 plus a NOx levy of maybe €500. Total VRT: €3,740.
You can challenge the OMSP if you think it's wrong, but you need evidence. Recent ads for similar cars, a dealer valuation, an independent appraisal. Revenue doesn't just take your word for it. And remember, challenging it can delay your registration.
Full Cost Example: Importing a UK Car
Let's put it all together with a realistic example. You're importing a 2018 BMW 520d M Sport from England.
- Purchase price: £16,000 (€18,400)
- Shipping from Liverpool to Dublin: €400
- Transit insurance: €200
- Customs value: €19,000
- Customs duty at 10%: €1,900
- Value for VAT: €20,900
- VAT at 23%: €4,807
- Import taxes total: €6,707
Now VRT:
- Revenue OMSP assessment: €22,000
- CO2 emissions: about 135g/km (Band B2, 16%)
- VRT = €22,000 x 16% = €3,520
- NOx levy: approximately €900
- Total VRT: €4,420
Total landed cost:
€18,400 (purchase) + €600 (shipping/insurance) + €6,707 (customs/VAT) + €4,420 (VRT) = €30,127
That's €11,727 in taxes on an €18,400 car. Almost 64% of the purchase price in additional charges.
Would the same car cost €30,000 in Ireland? Probably. A 2018 520d M Sport from an Irish dealer would be around €28,000 to €33,000 depending on mileage. So you might break even or save a little. But you've taken on all the hassle of importing for a marginal saving. That's the reality for a lot of mid-range UK imports.
How Northern Ireland Is Different
Northern Ireland is the exception that confuses everyone. Under the Windsor Framework (the renegotiated Northern Ireland Protocol), NI remains aligned with EU customs rules while also being part of the UK customs territory. For car imports to Ireland, this means NI is treated differently from GB.
If the car you're importing was already in free circulation in Northern Ireland - meaning it was bought and used in NI, not imported from GB - then you generally don't have to pay customs duty or import VAT when bringing it to Ireland. You just pay VRT at registration.
This is a real saving. Going back to the BMW example above, importing the same car from NI rather than GB would save you the €6,707 in customs duty and VAT. You'd only pay the VRT of €4,420. That makes the total landed cost €23,420 instead of €30,127.
But - and this is a big but - Revenue requires proof that the car was genuinely in free circulation in NI. The typical evidence they want is:
- The NI registration document showing a NI keeper address
- Evidence of use in NI (MOT certificates, service history from NI garages, insurance documents showing NI use)
- Proof that the car wasn't recently imported from GB to NI solely to avoid tax
Revenue has become increasingly strict about this. They've seen people buy cars in England, register them in NI for a few weeks, then try to bring them to Ireland tax-free. That's tax avoidance and Revenue will treat it as such. If they suspect the car was only briefly in NI, they'll demand customs duty and VAT on the GB import.
My advice: if you're buying from NI, ask the seller how long they've owned the car, where it was first registered, and whether they have paperwork showing NI use. If the seller is evasive, walk away.
Insurance for UK Imports: What You Need
Getting insurance for an imported car while it's still on UK plates and waiting for registration can be awkward. Most Irish insurers want to see an Irish registration number before they'll give you a quote. But you can't get Irish registration until the VRT is paid. It's a chicken-and-egg problem.
Here's how people usually handle it. Some insurers offer transit insurance that covers the car from the point of purchase to the NCTS appointment. This is typically a short-term policy covering 7 to 30 days. Companies like AXA and Allianz offer this, but you need to ask specifically for import transit cover. It's not something they advertise.
Once the car has Irish plates, you can get standard Irish insurance. Some insurers specialise in imported vehicles and are more understanding of the paperwork delays. It's worth shopping around rather than going with the first quote you get.
One thing I'd warn against: driving without insurance because "it's only for a few days until I get the plates sorted." The penalty for driving without insurance in Ireland is severe - a court appearance, five penalty points, and fines up to €5,000. On a car that's not even registered yet, the consequences would be worse. Don't risk it.
What About Cars Bought in the UK But Made in the EU?
There's a common belief that if you buy a German-made car from a UK dealer, you can avoid customs duty because the car was originally made in the EU. This is not how it works.
Customs duty is determined by the customs status of the goods at the time of import into the EU, not their country of manufacture. A BMW built in Germany, sold to a UK dealer, and then purchased by you in the UK - that car has been in free circulation in the UK. When it enters Ireland from the UK, it's subject to customs duty because it's arriving from a non-EU country.
The exception would be if you can prove, through a statement of origin or EUR1 certificate, that the car has EU preferential origin. In practice, used cars rarely come with this paperwork.
Customs Documentation: What You Need to Bring
When you go to the NCTS for VRT registration, you need to bring your customs clearance documentation. Specifically:
- The SAD (Single Administrative Document) or C88 form from customs clearance
- Proof that customs duty was paid
- Proof that import VAT was paid
- The UK V5C logbook
- Proof of purchase (invoice)
- Shipping documents (bill of lading or CMR consignment note)
- Photo ID
- Proof of address in Ireland
Without the customs clearance proof, the NCTS can't confirm that import taxes were paid. And if they can't confirm that, they won't register the car. Simple as that.
I've heard from people who lost their customs paperwork and had to go back to Revenue for a duplicate, which took weeks. Keep a digital copy and a physical copy in separate places.
Strategies to Reduce Your UK Import Tax Bill
You can't avoid customs duty and VAT legally on most GB imports. But there are ways to minimise the damage.
Look at NI cars first. If you can find the car you want in Northern Ireland and verify it was in free circulation there, you save the €6,000-plus in customs and VAT. That's not a small saving.
Factor the exchange rate. Sterling fluctuates against the euro. If GBP is weak, your UK purchase is cheaper in euro terms. But remember: customs duty and VAT are calculated on the euro equivalent at the time of import. The exchange rate on the day your customs declaration is filed determines your tax bill, not the rate on the day you bought the car.
Minimise shipping costs. Since shipping is part of the customs value, overpaying on transport increases your customs duty and VAT. Cheapest shipping option that's still reliable. Ro-Ro ferry transport from Holyhead or Liverpool to Dublin is the standard and costs €250 to €500.
Choose lower-emission cars. VRT is tied to CO2 emissions. A petrol hybrid will have a lower VRT percentage than a diesel saloon. If you're importing anyway, why not choose a car that costs less to register?
Get an OMSP estimate before you buy. Use Revenue's VRT enquiry system. You'll need the car's VIN, make, model, and year. The estimate isn't binding, but it tells you whether Revenue's valuation is in your ballpark.
Timeline: What to Expect When Importing from the UK
Here's a realistic timeline for a UK car import, assuming nothing goes wrong:
Week 1: Buy the car, arrange shipping, get the V5C and paperwork from the seller
Week 2: Car arrives at Irish port. Customs agent files the declaration. Pay customs duty and VAT. Car is released from customs (2 to 5 days at the port)
Week 3: Book NCTS appointment (online). Depending on the waiting list, this might be in Week 4 or Week 5
Weeks 4 to 5: NCTS appointment. Pay VRT. Get Irish plates
Week 5+: Pay motor tax, arrange Irish insurance, get an NCT test booked if the car is over 4 years old
Total: 4 to 6 weeks from purchase to driving on Irish plates. That's assuming no hiccups. If the customs declaration has issues, add 2 weeks. If Revenue challenges the OMSP, add another 2 to 4 weeks.
One pattern I see over and over: people try to save money by skipping the customs agent or driving the car onto the ferry without a proper import declaration. This nearly always backfires. Revenue has systems in place to track vehicles entering the country, and if your car shows up for VRT registration without proper customs clearance, the questions get very awkward. Pay the professionals. It's cheaper than the alternative.
Frequently Asked Questions About UK Imports
Can I drive my UK car in Ireland while waiting for registration?
No. Once the car arrives in Ireland, it needs to be registered within 30 days. You can't legally drive it on UK plates in Ireland during that period unless you have specific transit cover and temporary import permission, which is rare for private imports.
What if I bring the car myself on the ferry?
It doesn't change the tax calculation. You still need customs clearance. Driving the car onto the ferry yourself doesn't bypass customs. You still need to submit a customs declaration and pay what's due.
Do I pay UK VAT when buying in the UK?
If you buy from a UK dealer, you'll typically pay UK VAT at 20% if the car is sold as a VAT-qualifying vehicle. However, if the car is sold under the Margin Scheme (common for used cars), no VAT is charged. Either way, you'll still owe Irish import VAT when the car arrives.
Is there any relief for moving home from the UK?
Yes. If you're moving your residence to Ireland from the UK, you may qualify for Transfer of Residence relief on customs duty and VAT. This requires proof that you lived in the UK for at least 12 months and owned the car for at least 6 months before moving. You still pay VRT at registration, but you save the import taxes.
Can I register a UK car without a Certificate of Conformity?
Yes, for used cars this is common. Revenue will assess the car based on the UK registration document and their own data. However, not having a CoC can slow down the VRT assessment, and Revenue might apply standard values for emissions which could increase your VRT.
One last thing I want to emphasise. The rules for UK imports have changed several times since Brexit and they may change again. The Windsor Framework is still being implemented, and trade agreements can be renegotiated. Always check Revenue.ie for the current rules before you commit to a purchase. What was true six months ago might not be true today. A quick check of the Revenue website or a phone call to a customs agent could save you thousands.
