Estimate Your Irish Motor Tax
Use this free Irish road tax calculator to estimate annual tax for private cars in Ireland. Choose the method that applies to your vehicle: CO2 emissions, engine size, or the electric vehicle flat rate.
Important: This tool provides an estimate for private passenger cars. Official liability can vary by registration details, commercial classification, exemptions, and policy updates. Always confirm with the official motor tax service in Ireland.
How the Irish road tax calculator works
This calculator helps you quickly estimate what you might pay for Irish motor tax based on the most common private car methods:

- Engine-size motor tax for many older private cars.
- Flat EV rate for fully electric private vehicles.
After calculating your annual amount, the tool also shows estimated 3-month and 6-month options, plus a simple monthly budget estimate to help with planning.
