Hi Pat,

Yup, such are the vagaries of the CO₂-based tax system that we switched to in 2008. The idea was to reward those choosing vehicles with lower emissions, and that is often most starkly shown up when you start looking at older cars with larger engines versus newer models, which probably have much more power, but have smaller, more efficient engines. Of course there’s an argument that says that keeping an old car going, rather than buying a new one, is actually overall better for the environment, but that’s not going to wash with the tax authorities I’m afraid.

Hi Tommy,

Sorry, but no. As far as Revenue and the motor tax system are concerned, a car will always be taxed on its original, homologated figure, whether that be the engine’s swept capacity or its CO₂ emissions.  An LPG conversion is considered an aftermarket modification and so isn’t taken into account for tax purposes.

Hi John,

That model has CO₂ emissions of 179g/km, so will have annual motor tax of €750.

Hi Martin,

Yup, the problem is that 2008 was the switchover year to CO₂-based taxation, and the old Toyota petrol engines were pretty high up the charts in that respect. Actually, are you sure it’s 1.4? Because we only have data for a Corolla Verso with a 1.6-litre engine from that year. That engine had emissions of 177g/km, which would account for the high motor tax cost, but in theory a vehicle bought in 2008 should be eligible to revert to the old engine capacity system, which would bring down the cost a little. It’s certainly worth raising the issue with your local motor tax office to see what’s possible.

Hi Kevin,

Yes, I would definitely query that with the motor tax office — in theory, when you use a commercial vehicle for private use it reverts to the old by-engine-capacity tax system, so you should not be paying the CO₂ rate. Call and ask them to double-check that and you may be refunded the difference.

Hi Nicola,

Sadly, that is the correct rate. A 2009 Auris, which would have been on the CO₂ tax system from the get-go, with the 1.4-litre VVTi petrol engine, has CO₂ emissions of 163g/km, and is therefore liable for €570 a year in motor tax or, as you currently pay, €160 every quarter.

Hi Derek,

It depends on which petrol-engined version of the Audi A1 that you mean. The basic 1.2 TFSI, with 86hp, has CO₂ emissions of 118g/km, so will cost €200 a year to tax. The 122hp 1.4-litre TFSI has CO₂ emissions of 126g/km, so will cost €270 a year. Oddly, the more powerful 140hp engine is rated at between 109g/km and 113g/km, so will cost between €190 and €200 a year.

Hi David,

OK, this one could be a bit of a problem. We’ve asked Mercedes about this but so far no-one there has been able to track down a correct or reliable figure. The problem is that the law states "If satisfactory evidence of NOx emissions cannot be provided the following maximum charges will apply: For Diesel vehicles that is €4,850.” Which is a lot of money.

If the car comes with an original certificate of conformity (unlikely) then the NOx figure may well be on that, but it was not a figure that many took much notice of in the nineties. Perhaps the best bet would be to wait until 2023, when the car will be 30 years old and then you can import it as a classic?

Hi Mark,

There was indeed a clampdown on crew-cabs and five-seat SUVs qualifying for commercial rate VRT and tax, but being as (a) this Defender pre-dates the clampdown and (b) it has a separate and un-glazed cargo compartment, it should just squeak through.

Hi Alina,

It’s actually a pretty easy distinction. Motor tax is the Irish equivalent of the UK’s Road Fund Licence. It’s paid annually, and is based on the CO₂ emissions of the vehicle. The cheapest rate is for  cars that emit no CO₂ (i.e. electric cars), which cost €120 a year to tax, while the most expensive rate is for cars emitting more than 225g/km of CO₂, which is €2,350 a year.
