How a 2008 car is taxed
2008 is the tricky year. Cars first registered before 1 July 2008 are taxed on engine size; from 1 July they're taxed on CO2. Two identical 2008 cars can pay very different amounts, so check the first-registration date 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 →
