Here is a quick reference table summarizing the key differences between checking car tax in Ireland and the UK.

How can I check my car tax online in Ireland?

In Ireland, the official portal for all motor tax queries is motortax.ie, operated by the Department of Transport. The site lets you check the current tax status of any vehicle and renew or amend motor tax quickly.

Step-by-step guide to using motortax.ie

1. Go to motortax.ie and select “Check motor tax” or “Renew motor tax”.
2. Enter your vehicle registration number (the licence plate).
3. Enter your Personal Identification Number (PIN) – this is printed on your renewal notice or on a previous motor tax disc.
4. View your current tax status, expiry date, and any outstanding amounts.

You can also email motortax@transport.gov.ie for progress updates on an application, according to the official Motor Tax Information page.

The implication: the PIN is essential – without it, you cannot complete an online check. Keep your renewal notice or disc safe.

What you need: registration number and PIN

You must have both the vehicle registration number and a valid PIN. The PIN is originally sent with your renewal notice (Form RF200) and is also printed on the motor tax disc you receive. If you have neither, you can request a new PIN through the motortax.ie site or by calling the Motor Tax Section at 01-888 9000.

Alternative: checking by email

If you cannot access the website, you can email motortax@transport.gov.ie with your vehicle registration number and ask for a status update. However, the official site warns that email responses may take several days, so the portal is faster.

What is the official UK government service for checking vehicle tax?

In the UK, the single authoritative online tool is gov.uk/check-vehicle-tax, run by the Driver and Vehicle Licensing Agency (DVLA). It’s free, instant, and also shows the vehicle’s MOT test status and tax band.

In Northern Ireland, to tax a vehicle at a Post Office, you also need a paper copy of an insurance certificate or cover note and an original MOT test certificate or evidence of a Temporary Exemption Certificate (TEC). — GOV.UK

Using gov.uk/check-vehicle-tax

1. Visit gov.uk/check-vehicle-tax.
2. Enter the vehicle registration number.
3. The system returns current tax status, MOT expiry date, and the vehicle’s tax band (based on CO₂ emissions and fuel type).

Information required: 11-digit reference number from V5C

For a full check that includes the exact tax rate and renewal details, you’ll need the 11-digit reference number from your vehicle log book (V5C). This is printed on the front page. Without it, you can still see basic tax status (taxed or not taxed), but not the precise rate or due date.

What the check reveals: tax status, MOT expiry, tax band

The tool displays:

• Whether the vehicle is currently taxed or has a Statutory Off Road Notification (SORN).
• The date the current tax expires.
• MOT test expiry date (if applicable).
• Vehicle tax band – used to calculate annual rates.

Why this matters: if you’re buying a used car in the UK, this check confirms the seller hasn’t hidden unpaid tax.

What information do I need to check my car tax?

The documents you need differ between Ireland and the UK. Here’s a breakdown.

For Ireland: registration number and PIN

The Irish system requires the vehicle registration plate and a PIN (usually from the renewal notice RF200 or the current motor tax disc). Without the PIN, you cannot proceed online. You can request a new PIN via motortax.ie using your PPS number and vehicle registration, or call the Motor Tax Section.

For the UK: V5C reference number (11 digits)

The UK’s gov.uk tool asks for the registration number and optionally the 11-digit reference from the V5C log book. If you don’t have the V5C, you can still see basic tax status, but the official GOV.UK vehicle tax page advises applying for a new log book if you need to tax the vehicle.

Post Office confirms that a valid MOT certificate must be valid from the date the vehicle tax starts or the date the tax is issued, whichever is later. — Post Office guidance

If you don’t have the PIN or V5C

In Ireland, contact your local motor tax office or use the online PIN request. In the UK, contact the DVLA (phone 0300 790 6802) to order a replacement V5C. In both jurisdictions, you can also visit a motor tax office (Ireland) or a Post Office that offers vehicle tax services (UK) with acceptable identification.

What are the current motor tax rates in Ireland?

Irish motor tax rates depend on when the vehicle was first registered. Use the official motor tax calculator to find your exact rate, but here’s the framework.

Rates for pre-2008 vehicles (based on engine size)

Vehicles registered before 1 July 2008 are taxed by engine capacity (cc). Annual rates range from €118 for small engines (under 1,000cc) up to €2,235 for engines over 3,000cc, according to Citizens Information (Ireland’s official public service guide).

Rates for post-2008 vehicles (based on CO₂ emissions)

Vehicles registered after 1 July 2008 are taxed by CO₂ emissions band. Rates start at €120 for Band A (0-80 g/km) and rise to €2,350 for Band G (over 225 g/km). The full table is available on the GOV.UK vehicle tax rate tables (for comparison) and the Department of Transport, Tourism and Sport motor tax page.

Electric vehicle rates and exemptions

Electric vehicles (EVs) registered in Ireland pay a reduced annual rate of €120 as of 2024. This is subject to annual budget changes. In the UK, EVs are currently exempt from vehicle tax (VED) for first-year rates, though standard rates apply from the second year.

What this means: whether you drive a 1995 hatchback or a 2023 EV, the rate formula is predictable once you know your registration date and emissions — the calculators do the hard part.

How do I renew my motor tax online?

Renewal is straightforward on both sides of the Irish Sea, but the exact steps differ slightly.

Renewal process on motortax.ie

1. Go to motortax.ie and click “Renew motor tax”.
2. Enter your vehicle registration number and PIN.
3. Confirm your vehicle details and select the tax period (3, 6, or 12 months).
4. Choose payment method: debit/credit card or set up a Direct Debit for future renewals.
5. Submit – you’ll receive a confirmation and the motor tax disc will be posted within 2-5 business days.

Payment options (debit/credit card, direct debit)

Renew online using Laser, Visa, or MasterCard. You can also set up a Direct Debit to renew automatically every year (or every quarter if you choose a shorter period). Direct Debit is the simplest way to avoid lapses.

What to do if you haven’t received your renewal PIN

If your PIN is lost, request a new one through motortax.ie by entering your PPS number and vehicle registration. You can also call the Motor Tax Section (01 888 9000) or visit your local motor tax office in person.

The trade-off: choosing Direct Debit means you never miss a renewal, but you lose the disc as a physical reminder. Either way, checking your tax status online once a year is a sensible habit.

The catch: setting up Direct Debit eliminates the risk of forgetting, but only if your payment details stay current — monitor your bank statements for renewal debits.

For drivers in Northern Ireland, the process is equally straightforward using Northern Irelands free checker provided by nidirect.
