Can the fuel I put in affect my car's emissions?
I accidentally put E05 petrol in the car immediately prior to its NCT test last week. About 11 litres was put in with the remaining seven litres of E10 left in the tank. The CO emissions were off the charts (1.41 instead of 0.11 in March). I was wondering if, given that E05 is more like 97 octane, would it be the reason for the high numbers? If I had known that E05 was like 97 octane I would not have got it as it was not an emergency.

Hi Joe,
There's no easy answer to this as every car has a different set of sensors and calibration. In short, the level of ethanol in the fuel can certainly affect a car's emissions, but we're surprised by the jump in the level recorded and don't think that alone would account for it unless something very odd is going on with the engine control unit.
Where to get CO2 figure for a Japanese Toyota GT86?
Hello.
Where I can get Japanese CO2 emissions for a 2014 Toyota GT86, model DBA-ZN6, engine code FA20?

Hi Marek,
Go to https://www.mlit.go.jp/jidosha/jidosha_fr10_000019.html (and use a browser that will automatically translate it from Japanese to English for you) and scroll down to item 6 and get Excel files full of information for loads of JDM cars. Those hold engine codes, etc, fuel consumption and CO2 data.
We found several entries for the Toyota you mentioned, with CO2 varying from 173-187g/km depending on the specific version of car.
If you're importing this car, Revenue will likely take the official NEDC CO2 figure for the European market and 'uplift' it to WLTP standards, meaning that even the automatic model will likely be in Band F (191-225g/km), while the manual may be in Band G (226g/km and higher).

Hi Charles,
You've not mentioned which engine or which version of the car as the CO2 emissions vary considerably. It could be as low as €210 per annum if the emissions are under 140g/km in a model with the 2.0 TDI engine, for example, while the plug-in hybrid models are only €140 a year to tax.

Hi Donal,
Our records suggest that's a 2020-on Mercedes V 220 d, but its CO2 rating will depend on which specific variant it is. Some have emissions as low as 185g/km, but others 200g/km.
Can I convert a Land Cruiser before importing it?
Hi,
I'm buying a 2005 Toyota Land Cruiser SWB in Northern Ireland where it has been registered from new. It's a passenger version. My question is, can I take out the seats and register it as commercial in the south or if not, can it be registered as commercial in NI first before I bring it in or is it not worth the hassle?
What roughly would the VRT be?
Dermot (Louth)Apr 2025 Filed under: commercial vehicle
Expert answer
Hi Dermot,
The conversion work would either have to be done (and certified) before importation (in which case it could be imported as a commercial) or the Land Cruiser would have to be imported as a passenger car and the conversion carried out afterwards. Either way it's a lot of hassle for sure.
As a passenger car, the Land Cruiser would likely attract 30 per cent VRT. That's 30 per cent of the Open Market Selling Price (OMSP) as determined by Revenue. If we assume that's €8,000, then the VRT would be €2,400. And the NOx levy would be on top of that - up to a maximum of €4,850 for diesel cars if you can't prove it has a lower level of NOx emissions.
How much BIK on a Volkswagen Amarok?
I'm looking at buying a new VW Amarok Aventura for around €80k including VAT. It will primarily be used for work, but I will on occasion use it for personal use. How do I work out the BIK?
Paul (Athlone)Apr 2025 Filed under: benefit-in-kind
Expert answer
Hi Paul,
Revenue is likely to treat that vehicle as a company car – not a van – due to it having rear seats, a high specification and suitability for use as a regular car. That's irrelevant of what you actually do with it.
BIK is calculated using the Original Market Value (OMV), a percentage determined by the car's CO2 emissions and the annual business mileage. In the case of the Amarok Aventura, the CO2 is 267g/km, and the retail-on-the-road price is €76,820 before options.
Such a high emissions rating puts this vehicle into the highest band for BIK, category E, and the percentage then depends on the annual business mileage from a high of 37.5 per cent for up to 26,000km to a low of 15 per cent for over 52,001km (it's 30 per cent for 26,001-39,000km and 22.5 per cent for 39,001-52,000km). You must keep records.
Say for example you do 25,000km a year for business reasons. That means 37.5 per cent of €76,820 as the calculated “cash equivalent” (€28,807.50) and that is then added to your total pay from a tax calculation point of view.
You can bring that down by doing more business mileage or choosing a more efficient – or cheaper – vehicle.
There are plenty of other bits and pieces to take into consideration, so it's worth taking a look at Revenue's own Private use of employer provided vehicles page for up-to-date information.
Are these VRT estimates on a Transit Custom right?!
Hello,
I am looking to buy a family nine-seater like the Ford Tourneo Custom in NI. Unfortunately, Revenue's VRT calculator can't find anything from the years I've searched (2018, 2019, 2020), giving me a "No vehicle found for combination selected" error.
I tried vrt.ie, but it's giving me very high estimates. Could they be true?
For example, for a Feb 2019 Ford Tourneo Custom 2.0 EcoBlue 130hp Titanium, asking price £20,000, it came out at €16,493.48 CO2 (WTLP CO2 emissions: 215.867g/km, which seems crazy?) and €2,625 NOx charge.
For another specimen, a Jan 2020 Ford Tourneo 2.0 EcoBlue 130hp Titanium, they came at €8,979.6 CO2 (WTLP CO2 emissions: 164g/km) and €2,625 NOx.
Are these estimations even realistic? NOx is most certainly not right, but even the CO2 part seems excessive. But it's my first rodeo, so I really don't know! I would be very grateful for any clues.

Expert answer
Hi Slawek,
We've found Revenue's VRT estimator to be lacking in a lot of ways and it certainly doesn't list all makes and models for all years.
Let's break down the figures.
First up, the NOx levy quoted by vrt.ie (€2,650) is actually the maximum possible charged for a vehicle with a diesel engine. Neither of the examples you provided will emit enough NOx to warrant that, though you will need to have proof of their official figure to avoid paying the maximum. We'd estimate that a NOx levy of about €250 is more realistic in this case.
Be careful with the CO2 figures. The 164g/km rating quoted for the second vehicle appears to be the old NEDC figure and Revenue will actually apply an “uplift” formula (see our Guide to Importing Cars from the UK feature for that) to bring it up to an equivalent WLTP rating. It comes out as 204g/km, meaning VRT at 41 per cent.
In your first example, this appears to have been done already, resulting in the 215g/km rating.
In both cases, that would mean VRT at 41 per cent of the OMSP, the Open Market Selling Price.
Now this is where things become less clear. The OMSP is not the asking price of the car, or even the price you pay for it, but the value Revenue places on it as a vehicle registered in Ireland and on sale here. It's not easy to estimate for relatively rare vehicles. For the purposes of our calculation, let's say €45,000. At 41 per cent, the VRT on that would be €18,450.
Obviously that could go up or down depending on how much Revenue believes the vehicle is worth, but we're certain of the 41 per cent VRT rate, unfortunately.
Is the tax on this 2008 2.0-litre petrol car correct?
Hi there,
I'm looking to buy an already imported car here in Ireland. It's already imported and registered by a private seller. He claims the motor tax is only 400 Euro but it's a 2008 2.0-litre petrol model emitting 199g/km.
When I check the motor tax rates for this car it should be a lot higher with both rates before and after July 2008.
When I check the reg number on Revenue's site it does come back at 400 Euro.
Is this a mistake? So how much would my motor tax be if I imported the same car with the same engine and CO2 emissions?
Thanks so much for your help in advance.
Kind regards
Ed (Leixlip)Apr 2025 Filed under: taxation
Expert answer
Hi Ed,
The only tax rate that is exactly €400 is for cars registered between 2008 and 2021 with CO2 emissions of 141-155g/km. If the car in question actually emits 199g/km then there does appear to have been a mistake made.
Unfortunately, that has no bearing on what would happen if you imported such a car yourself. In fact, if the 199g/km rating is according to the old “NEDC” system, then Revenue will uplift it to an equivalent WLTP figure for VRT and tax calculations. It comes out as 298g/km, meaning a potential €2,400 per year motor tax bill.
If the 199g/km is actually the WLTP figure, then the annual bill is a more palatable €790.
Need to calculate VRT and NOx levy for this Audi A3...
Hi
I'm looking to import a 2014 Audi A3 Cabriolet from Northern Ireland into the Republic but on the Revenue VRT website there's no mention of the convertible model.
What do I need to calculate the exact VRT I would pay? Also, how can I find what the NOx emissions are for this specific make/model car as this also affects the VRT calculation?
Thanks for your help
John (Dublin)Apr 2025 Filed under: importing
Expert answer
Hi John,
There's no way to know for sure the exact VRT due until the car is brought for inspection at an NCT centre after importing it. Even if the car appears on Revenue's site, there are disclaimers on there indicating that it's an estimate only.
To make your own estimate, you'll need to have the CO2 figure of the specific car you're looking at and you'll need to guess what Revenue will say the Open Market Selling Price (OMSP) is for that car.
The latter is the figure Revenue believes the car to be worth as an Irish car selling on the open market today. It's not easy to estimate for a relatively rare model such as the A3 Cabriolet. We found one from 2014 listed on Carzone for about €16,000, which is probably as good a starting point as any.
Watch out with the CO2 figure. The official figure for a 2014 car is likely to be according to the old “NEDC” system and unless a WLTP figure is available Revenue will use its “uplifting” formula to bring the CO2 up. You'll find that formula in our Guide to Importing Cars from the UK page (it applies no matter where the car is coming from).
Once you have your CO2 figure you can look up the VRT band and percentage on our How Much VRT is Paid in Ireland? page. The VRT due will then be that percentage of the OMSP.
The NOx levy is separate to this calculation – though payable at the same time. It's not so easy to look the NOx emissions up and hopefully the car in question has a certificate of conformity with the information on it. There's a bit about that on the Guide to Importing Cars from the UK page mentioned above that again applies no matter where the car is coming from.
Hopefully that all helps. If you want us to assist with the calculations, come back to us with as much detail as possible on the car in question.
Is the WLTP CO2 figure needed for VRT calculation?
When calculating VRT is the band rate what you pay at the WLTP CO2 rate or the CO2 that is on the V5?
Domnick Taaffe (Dublin)Mar 2025 Filed under: VRT
Expert answer
Hi Domnick,
If the V5 shows the WLTP CO2 emissions, or the WLTP rate is available for the car in question, then that is what the VRT band will be based on. If the WLTP rate is not shown or not available then Revenue will apply an 'uplifting' formula to the CO2 emissions figure in a bid to bring it up to a WLTP-equivalent value.
We go into more detail on the actual uplift formula etc. in our Guide to Importing Cars from the UK feature if you're interested, but don't hesitate to come back to us for more help if you need it.
