Department of Transport statutory rates
\text{Post-2008 CO2 Tax} = f(\text{WLTP/NEDC CO2 Band A0–G}) \\
\text{Pre-2008 CC Tax} = f(\text{Engine Capacity cc}) \\
\text{Half-Year (6 Mo)} = \text{Round}(\text{Annual} \times 55.5\%) \\
\text{Quarterly (3 Mo)} = \text{Round}(\text{Annual} \times 28.2\%)Cars registered in Ireland on or after 1 July 2008 are taxed based on CO2 emissions (from €120 for EVs up to €2,400 for high-polluting vehicles). Pre-July 2008 cars remain taxed based on engine cubic capacity (cc). Paying half-yearly costs 55.5% of the annual rate (an 11% surcharge over 12 months), while paying quarterly costs 28.2% (a 12.8% surcharge over 12 months).
