How do I get a pin number to tax my car online?
Where can I find my tax PIN?
- For vehicles previously taxed in Ireland, the PIN is the last six digits of the Vehicle Registration Certificate number, according to Louth County Council motor tax page.
- For a brand new or imported vehicle being taxed for the first time, the PIN is reportedly the last six characters of the vehicle chassis number (VIN), as explained by its4women insurance guide.
- The PIN is case-sensitive and required for first-time online motor tax payment.
The implication: Your VRC is the master key. Keep it safe, because without those six digits you’re locked out of the online service.
Can I tax my car online without a PIN?
- If you’ve taxed the vehicle online before, you can use the last six characters of the VRC number instead of the PIN.
- If you’ve lost your PIN, the motortax.ie portal includes a PIN retrieval function – Tipperary County Council states that a retrieved PIN should issue straight away through the online PIN retrieval function.
- For first-time taxing without a PIN, you must visit a motor tax office in person.
Without your VRC or a retrieved PIN, the online service is inaccessible. Motorists who lose both must queue at a motor tax office – the very queue they were trying to avoid.
The pattern: PIN retrieval is instant online, but only if you already have access to the portal with another credential. For first-timers, there is no workaround – the PIN lives on your VRC.
How do I tax my car online in Ireland?
What is the motor tax online login procedure?
- Visit www.motortax.ie – the official online portal for Irish motor tax, operated by the Department of Transport.
- Enter the vehicle registration number and either the PIN or the last six digits of the VRC number.
- The system will display your vehicle details – check they are correct before proceeding.
- Enter current vehicle insurance details, including the insurer name, policy number, and expiry date, as the its4women insurance guide notes.
This step is critical: the system cross-checks your insurance with the national database before allowing payment.
How do I pay motor tax online?
- Select the tax period: 3, 6, or 12 months.
- Pay by debit or credit card (Visa, Mastercard).
- After successful payment, a confirmation receipt is issued – Citizens Information advises printing or saving this receipt and keeping it in the vehicle until the official motor tax disc arrives by post.
- The disc is posted within 2–5 working days.
The digital receipt is your only proof of tax until the disc lands. Gardaí can check the national database, but having a printed receipt in your glovebox avoids roadside inconvenience. Don’t toss it.
The trade-off: online tax is fast and convenient, but it shifts the burden onto you to keep the receipt safe and manage the 2-5 day delivery window. If you need tax immediately, a local motor tax office can issue a disc on the spot.
How do I tax my car after change of ownership?
Do I need a new PIN after buying a used car?
- When a vehicle changes ownership, the new owner must tax it before driving – the previous owner’s tax is not transferable.
- The new owner uses the VRC issued during registration to tax online. The PIN on that new VRC is the key.
- If the VRC is not yet available, a temporary PIN can be obtained from the local motor tax office.
The change of ownership must first be registered with the Department of Transport. Without that, the system won’t recognise you as the owner.
Can I transfer the existing tax?
- No. If you buy a used car, any remaining tax on the seller’s disc is lost. You must purchase a new tax disc in your own name.
- This applies to both online and in-person renewals.
The pattern: the tax is tied to the owner, not the car. Buying a used car means you start from zero – budget for the tax immediately.
Can I drive while waiting for a tax disc?
Can you drive a car without tax if you just bought it in Ireland?
- Driving without a valid tax disc is illegal in Ireland and the UK. Citizens Information states that penalties include fines, penalty points, and possible vehicle seizure.
- When you buy a used car, you cannot drive it until it is taxed in your name. There is no grace period.
- Waiting for the postal delivery of a disc does not exempt you from taxation – you must have the tax paid before taking the car on the road.
A common pitfall: buying a car on a weekend and assuming you can drive it home because the disc is in the post. If you’re stopped, the absence of a disc combined with no online record of tax in your name can lead to fines starting at €60 and escalating to court.
The consequence is clear: no tax disc, no drive. Even if you’ve just paid online and have a receipt, the physical disc (or a printed receipt) must be displayed – or you risk a penalty.
What is the first thing you do when you get a new car?
Do I need insurance before taxing?
- Yes. Vehicle insurance is a legal requirement before you can tax a car in Ireland.
- The online motor tax system asks for your insurer name, policy number, and expiry date – you cannot complete payment without this information.
- As the its4women insurance guide confirms, entering accurate insurance details is part of the tax application.
How do I register a new vehicle?
- For a brand new car, the dealer often handles initial registration and tax – you may only need to pay the first year’s tax as part of the purchase.
- For a used car imported from abroad, you must first register with the Department of Transport and obtain an Irish VRC. Then you can tax online using the PIN from that VRC.
- Once registered and insured, tax the vehicle online at motortax.ie before driving.
The order matters: Register → Insure → Tax → Drive. Breaking that sequence leaves you exposed to fines and invalid insurance.

Yes, the motortax.ie website is mobile-friendly. You can complete the entire process on a smartphone or tablet.
How do I check the current motor tax rate for my car?
Check the rate at motortax.ie after entering your vehicle registration – the system calculates the tax based on engine size and CO2 emissions, according to Government of Ireland guidance.
Is there a penalty for late motor tax renewal in Ireland?
Yes. If you’re late by more than a month, you cannot renew online – you must go to a motor tax office in person. Late renewals may also incur backdated charges.

You can request a duplicate disc from your local motor tax office. A small fee may apply.
Do I need an NCT (National Car Test) to tax my car in Ireland?
If your car is 4 years old or older, you must have a valid NCT certificate before renewing motor tax online. The system checks this automatically.
How do I tax a motorcycle online?
The same motortax.ie portal works for motorcycles. You’ll need the VRC or PIN as usual. Rates are based on engine size.
For Irish motorists, the choice to tax online is a no-brainer: it’s faster, available 24/7, and eliminates queuing. But the prerequisite – having your PIN and insurance details ready – is non-negotiable. If you’ve just bought a used car, budget for the tax before you drive off, and keep that VRC in a safe place. The online system works brilliantly when you’re prepared, and punishes you only when you’re not.
