How a 2015 car is taxed
A 2015 car is taxed on its official CO2 emissions (NEDC figure), in bands from A to G. The same engine can fall into different bands depending on body style, gearbox and economy versions, so the exact band is shown on the registration certificate.
Paying for 6 months costs 55.5% of the annual rate, and 3 months costs 28.25%, so paying yearly is cheapest. How Irish motor tax works →
