How a 2005 car is taxed
A 2005 car is taxed on engine size, because it was first registered before 1 July 2008. CO2 doesn't matter, so diesels and petrols with the same engine size pay the same.
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 →
