Ireland Car Tax Calculator
Use this calculator to estimate Irish private motor tax based on CO2 emissions, engine size, or electric vehicle status.
Find this on your Vehicle Registration Certificate (VRC).
3-month and 6-month payments are typically higher in total due to statutory multipliers.
How this car tax IE calculator works
Motor tax in Ireland is not one-size-fits-all. The amount you pay depends on how your vehicle is classified for tax purposes. This page gives you a practical estimate using common private car rules so you can budget quickly.
- CO2 method: Often applies to private cars first registered in/after July 2008.
- Engine size method: Common on older private cars.
- Electric vehicle method: Uses a flat annual amount for eligible BEVs.
- Vintage override: If the car is 30+ years old, a vintage flat rate may apply.
CO2-based private car tax bands (commonly used schedule)
For many Irish cars, annual motor tax is determined by CO2 emissions. The calculator uses the following band logic:
| Band | CO2 (g/km) | Annual Tax |
|---|---|---|
| A1 | 0–80 | €120 |
| A2 | 81–100 | €170 |
| A3 | 101–110 | €180 |
| A4 | 111–120 | €200 |
| A5 | 121–130 | €270 |
| A6 | 131–140 | €280 |
| A7 | 141–155 | €390 |
| A8 | 156–170 | €570 |
| A9 | 171–190 | €750 |
| A10 | 191–225 | €1,250 |
| A11 | 226+ | €2,400 |
Engine-size tax for older vehicles
If your car is taxed by engine capacity, the annual rate increases by cubic capacity (cc). The calculator includes the full stepped engine table from 1,000cc and below up to 3,001cc+.
Example engine brackets
- Up to 1,000cc: €199
- 1,401–1,500cc: €413
- 1,901–2,000cc: €710
- 2,501–2,600cc: €1,294
- 3,001cc and above: €1,809
Why 3-month and 6-month tax cost more over a year
In Ireland, part-year motor tax is normally calculated using multipliers (for example, around 28% for 3 months and 55% for 6 months). That means paying in shorter periods is convenient, but usually more expensive across a full year than one annual payment.
Tips to avoid mistakes
- Check your VRC for the exact CO2 value and taxation class.
- Do not mix WLTP/NEDC values unless your official document specifies the value used for tax.
- If your car is near 30 years old, confirm eligibility for vintage rate before renewal.
- Always verify the final amount on motortax.ie.
