How motor tax is worked out

The table that applies depends on the date the car was first registered:

  • From 1 January 2021: CO2 emissions on the WLTP test, in 16 bands.
  • 1 July 2008 to 31 December 2020: CO2 emissions on the older NEDC test, in bands A0 to G.
  • Before 1 July 2008: engine size in cc, in 100 cc steps.

Each band runs from just above the previous band's limit up to and including its own limit, so a car at exactly 120 g/km is in the lower band. A 6 month disc costs 55.5% of the annual rate and a 3 month disc 28.25%, with any cent dropped.

Example. A 2019 car with NEDC CO2 of 125 g/km is in band B1, at €270 a year. Paying every 3 months costs €76 a time, or €304 over the year: €34 more than one annual payment.

A 2022 car at 120 g/km WLTP is in band A6, at €190 a year. A 2005 car with a 1,598 cc engine pays €514 a year, or €285 every 6 months.

Questions

How much is motor tax in Ireland?
It depends on when the car was first registered. Cars from 2021 on pay €120 to €2,400 a year depending on WLTP CO2. Cars registered from July 2008 to 2020 pay €120 to €2,400 on NEDC CO2. Older cars pay €199 to €1,809 by engine size.
Does it cost more to tax a car for 3 or 6 months?
Yes. A 6 month disc costs 55.5% of the annual rate and a 3 month disc costs 28.25%, with cent dropped. Over a year that is about 11% and 13% more than paying for 12 months at once. On a €270 car, quarterly payments of €76 add up to €304.
Which CO2 figure do I use?
Cars first registered from 1 January 2021 are taxed on the WLTP figure. Cars registered from 1 July 2008 to the end of 2020 are taxed on the older NEDC figure, even if the car also has a WLTP figure. The figure on your vehicle registration certificate or current motor tax disc is the one used.
Is motor tax changing in Budget 2027?
No change to motor tax rates was announced in Budget 2027 on 6 October 2026. A weight based vehicle tax was discussed in pre-Budget papers but was not announced. The rates here have applied since 1 January 2021.
How much is motor tax on an electric car?
A fully electric car pays the lowest rate, €120 a year, under both CO2 tables.
What about cars registered in early 2008?
Cars first registered before 1 July 2008 are normally taxed on engine size. Some new cars registered between 1 January and 30 June 2008 were moved onto the CO2 system. If your motor tax disc shows a CO2 band, choose "From 1 July" for 2008.
What happens if I tax my car late?
Motor tax is backdated to when the last disc ran out. Arrears are charged at one tenth of the annual rate for each month, unless the car was declared off the road in advance.
Does this cover vans and commercial vehicles?
No. Goods vehicles are taxed on unladen weight and other vehicles have their own tables. This calculator covers private cars only. Check motortax.ie for other vehicles.
