Motor tax is one of the most common running costs for vehicle owners in Ireland, yet it’s also one of the most misunderstood. Whether you’re buying your first car, importing a vehicle, or simply trying to understand why your tax rate is what it is, this guide gives you a complete run down of all you need to know.
What is Motor Tax and Why Do I Need It?
Motor tax is a mandatory fee for using a vehicle on public roads in Ireland. You must display a valid motor tax disc clearly on your vehicle windscreen and driving without one can result in a €60 fine. A Motor Tax Disc can be purchased for 3, 6, or 12 months, and a replacement disc costs €6.
How Is Motor Tax Calculated?
Motor tax systems differ depending on the date your vehicle was first registered.
Helpful tools:
💡You can check your vehicle’s engine based tax rate using your registration number on the official motor tax website.
💡Everything you need to know about Motor Tax can be found on Citizens Information
1. Vehicles Registered Before 1st January 2008 (Engine Size System)
Private vehicles registered before 1st January 2008 and private goods vehicles such as vans are taxed based on engine capacity (cc). For Example:
- Up to 1,000cc → €199 per year
- Over 3,001cc → €1,809 per year
2. Vehicles Registered Between 1st January 2008 and 30th June 2008 (CO2 Emissions System)
Private vehicles first registered between 1st January 2008 and 30th June 2008 were previously taxed based on the Engine Capacity (cc) system. These vehicles were switched to the new CO2 Emissions System and this tax ban will remain with these vehicles until the vehicle end of life, even if motor tax rates change.
3. Vehicles Registered On or After 1st July 2008 Up To 31st December 2020 (CO2 Emissions System - NEDC)
For newer passenger cars, the tax rate is based on CO₂ emissions (g/km NEDC testing) instead of engine size. This change encourages more environmentally friendly car choices by offering lower rates for low polluting vehicles. For a full list of applicable rates click here. Some rate examples are:
- Zero emissions vehicles (electric cars) are taxed at the lowest rate of €120 per year
- 121 - 130 g/km CO₂ is taxed at €270 per year
- 171–190 g/km CO₂ is taxed at €790 per year
4. Vehicles Registered On or After 1st January 2021 (WLTP – Worldwide Harmonised Light Vehicle Test Procedure System)
For new cars registered from 1st January 2021 Ireland switched to WLTP which generally gives higher and more accurate CO2 figures than NEDC. For a full list of applicable rates click here. Some rate examples are:
- Zero emissions vehicles (electric cars) are taxed at the lowest rate of €120 per year
- 121 - 130 g/km CO₂ is taxed at €200 per year
- 171–190 g/km CO₂ is taxed at €600 per year
5. Commercial Vehicles (Unladen Weight System)
In the case of commercial vehicles, the registration tax is calculated by taking into account their unladen weight. When the gross weight of the vehicle doesn’t exceed 3,000 kg, a category that many vans and small trucks fall into, the registration tax is €333 per year. In the case of heavy vehicles from 4,000kg to 12,000kg the fee is €500 per year and for vehicles over 12,001kg, the fee is €900.
Taxing Your Car For The First Time
If you are taxing your car for the first time, you need to make sure that your name is on the Vehicle Registration Certificate (VRC). If you buy a new car from a registered dealer, the dealer will do this for you. If you buy a second hand car in a private sale, make sure the seller completes and signs the change of ownership section so that a new VRC can be sent to you. Without a VRC, you can’t tax your new car.
When taxing your new second-hand (previously taxed) car for the first time on MotorTax.ie you will be requested to enter your Vehicle Registration Number and a PIN. This PIN is the last 6 digits of your Vehicle Registration Certificate (VRC) number on the front top right corner of the VRC.
When taxing a brand new or imported car for the first time on MotorTax.ie you will be requested to enter your Vehicle Registration Number and a PIN. This PIN is the last 6 characters of your vehicles chassis number (VIN).
Paying or Renewing Your Car Tax
There are two ways you can renew and pay your motor tax:
- Online at MotorTax.ie. The fastest and easiest option. Enter your car registration number and the PIN which is the last 6 digits on your Vehicle Registration Certificate or as confirmed in your tax renewal email.
- In-person at your local Motor Tax Office
When paying your Motor tax you can choose to pay for three months, six months, or twelve months/1 year. However, paying for 12 months/full year generally works out slightly cheaper.
The following types of vehicles can be taxed and renewed online:
- Private cars
- Motorcycles
- Agricultural tractors, excavators or diggers and combine harvesters
- General haulage tractors
- Dumpers, off-road dumpers and forklifts
- Hearses
- Vintage or veteran vehicles
- Vehicles adapted for use by disabled persons
- SPSV vehicles (Taxi or hackney or limousine)
What Happens If You Don't Pay Your Motor Tax?
Failing to pay Motor Tax and driving in Ireland without valid motor tax is a serious road traffic offence and the penalties can escalate quickly. If you’re stopped while driving an untaxed vehicle, you may receive an on the spot fine of €60, which increases if it’s not paid on time. Continued non compliance or repeat offences can result in court fines of up to €1,000, and in more serious cases, the Gardaí have the power to impound or seize your vehicle.
Always keep proof that your tax is paid.
Older vehicles still require a physical motor tax disc displayed on the windscreen. Newer vehicles are recorded digitally, and Gardaí can verify tax status using ANPR (Automatic Number Plate Recognition). However, a physical disc must still be displayed on the windscreen to avoid penalties.
What If You Lose Your Motor Tax Disc?
If you have lost your Motor Tax Disc you must request a replacement disc which will incur a cost of €6.
To get a replacement disc, you need to:
- Complete an application for replacement document i.e. Form RF134 (pdf)
- Have the form witnessed by a member of the Garda Síochána at a Garda station
- Send your completed form with the appropriate fee to your local Motor Tax Office.
Motor Tax Exceptions & Special Cases
Some vehicles qualify for exemptions or reduced rates:
1. Vehicles Adapted for Drivers/Passengers with Disabilities
Vehicles specially manufactured or adapted for people with disabilities may qualify for exemption, provided the owner uses the vehicle and the engine capacity does not exceed 2,000cc.
2. Offshore Island Vehicles
Vehicles permanently kept and driven on certain offshore islands may qualify for reduced motor tax.
3. Vintage Vehicles (30+ Years Old)
If your car is over 30 years old, you qualify for reduced vintage rates:
- Cars = €56 per year
- Motorcycles = €26 per year
You must provide documentation proving the date of manufacture.
4. Rarely Used, Parked, or Stolen Vehicles
If your car will not be in use for 3 to 12 months, you can avoid paying motor tax by completing a Declaration of Non Use (Form RF150). This applies when the vehicle is:
- Parked long term
- Not being driven due to travel
- Stolen
- Scrapped
The declaration should be submitted in the same month your current tax expires, and you must have paid at least 3 months of tax prior.
In Summary
The Motor Tax system is designed to encourage drivers to choose cleaner and more efficient cars. Therefore, if you’re thinking of buying a car, either new or used, always check it’s CO2 emissions or engine size to avoid paying higher tax rates.
