The Basics of Car Tax in Ireland

Before we delve into the details of how to check your motor tax in Ireland, let’s start with the basics. Car tax, also known as motor tax, is a legal requirement for all roadworthy vehicles in Ireland. The revenue generated from car tax goes towards maintaining and improving the country’s road infrastructure. It’s an essential part of vehicle ownership and ensures that the roads you drive on are safe and well-maintained.

When it comes to paying your motor tax, you’ve got several choices. You can handle it online, make a trip to your local motor tax office, or opt for the traditional method of postal forms. Typically, you’ll receive a tax disc for a duration of 3, 6, or 12 months. The specific cost varies based on your vehicle type.

How Is Car Tax Calculated in Ireland?

Motor tax is determined by three key assessments, depending on your vehicle’s specifications:

Engine Size

If your vehicle was manufactured before July 2008, the motor tax calculation is primarily based on the size of your vehicle’s engine. Vehicles with larger engines generally incur higher motor tax rates.

CO2 Emissions (NEDC)

For vehicles registered between 1st July 2008 and 31st December 2020, motor tax is calculated based on the vehicle’s CO2 emissions using the New European Driving Cycle (NEDC) measurement. The amount you pay correlates with your vehicle’s emissions level.

CO2 Emissions (WLTP)

If your car was registered after January 1st, 2021, motor tax is calculated using the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) values for CO2 emissions. The tax rate is determined by your vehicle’s emissions in this case.

Understanding Car Tax Bands in Ireland

Tax in Ireland is not a one-size-fits-all fee. It varies based on several factors, including the type of vehicle you own and its emissions. These factors determine which car tax band your vehicle falls into. The Irish government uses a band system to categorise vehicles, with each band corresponding to a specific amount of tax.

In Ireland, motor tax for private vehicles is calculated based on various criteria depending on when the vehicle was first registered. Here’s a breakdown of how motor tax is determined:
