File RF150 at motortax.ie or your Motor Tax Office to pause motor tax for 3–12 calendar months. Must be filed in advance — in the month current tax or current declaration expires, or within 21 days of purchase for a new/imported vehicle. Retrospective declarations are impossible since 1 July 2013. If you're late, you must pay all arrears plus 3 months of motor tax before filing. During the off-road period the vehicle cannot be driven, parked on a public road, or used. Driving untaxed costs €60 FCN (rising to €240 / court summons). To bring the car back early, just renew motor tax. If the car is permanently finished, scrapping via an ATF and Certificate of Destruction is usually the better option.
What the off-road declaration actually does
Ireland's equivalent of the UK's SORN is a Declaration of Non-Use, filed using form RF150. It tells the Motor Tax Office that:
- The vehicle will not be used on a public road for a stated period
- The vehicle will not be parked on a public road during that period
- You are not liable for motor tax during the declared months
It's the mechanism Irish motor tax law provides for anyone who's taking a car out of use — overseas assignment, long holiday, seasonal storage, mechanical project, SORN-style hibernation — without accumulating motor tax arrears or incurring penalties for driving untaxed.
The timing trap — file in advance or lose
Since 1 July 2013, Irish law has blocked retrospective off-road declarations. The old loophole — signing an RF100A at a Garda Station saying the car "was" off the road — was closed after it was being used to dodge motor tax arrears. You must now file before the off-road period begins, not after.
The specific timing rules are:
| Situation | When you must file RF150 |
|---|---|
| Current motor tax is about to expire | In the same month motor tax expires |
| Current off-road declaration is about to expire | In the same month the current declaration expires |
| You just bought a second-hand car | Within 21 days of the date of sale |
| You just imported or registered a new vehicle | Within 21 days of registration |
Missing the window doesn't just delay — it triggers the arrears trap (see below). Set a calendar reminder 2–3 weeks before your current motor tax or declaration expires. odo.ie sends these automatically — see the CTA below.
Duration rules — 3 to 12 calendar months only
- Minimum: 3 calendar months
- Maximum: 12 calendar months
- Must be full calendar months — starting on the 1st of a month, ending on the last day of a month
- No 1- or 2-month options — for very short periods, you're generally better off paying for 3 months of tax
- Renewable — if you need longer than 12 months, file a new RF150 in the month your current declaration expires
If your off-road period will span, say, mid-March to mid-July, you have two cleaner options: declare from 1 April to 30 June (3 months, tax paid through end of March and from 1 July), or from 1 April to 31 July (4 months, tax paid through end of March and from 1 August).
How to file — online or in person
Online (fastest — motortax.ie)
- Go to motortax.ie
- Enter your vehicle registration number and the PIN from your most recent motor tax renewal reminder
- Select "Declare off the road"
- Confirm the start month and number of months (3–12)
- Review and submit — you receive a confirmation receipt
No PIN? Request a new one via motortax.ie or in person at any Motor Tax Office. The PIN is tied to the vehicle and sent to the registered owner's address on file.
Paper (Motor Tax Office)
- Download the RF150 form from motortax.ie or your county council's website
- Complete all fields (vehicle details, period, reason, signature)
- Submit to your local Motor Tax Office by post or in person
- If posting, allow sufficient time to arrive before the end of the filing month
What you can't do while the car is off the road
During the declared off-road period, the vehicle cannot be:
- Driven on a public road — under any circumstances
- Parked or left on a public road, including residential streets
- Towed on a public road without appropriate trade-plate or recovery arrangements
- Used in any way that brings it into the public road system
The vehicle must be kept on private property — a driveway, off-street parking, garage, farm yard, or other private land. Automatic Number Plate Recognition (ANPR) cameras flag untaxed vehicles automatically, and enforcement is routine, particularly near ports, motorway service areas and urban patrol routes.
If you need to move the car to a garage for repair during the off-road period, either: (a) briefly re-tax the car for the journey, or (b) have it recovered on a flatbed trailer by a professional recovery operator.
The arrears trap — the single biggest RF150 mistake
If you miss the filing window and your motor tax has already lapsed, you cannot simply file RF150 backdated to cover the missed period. You have to:
- Pay the full arrears of motor tax from the date it lapsed
- Pay at least 3 months of current motor tax on top
- Then file the RF150 for the period going forward
For a typical mid-band family car at €270/year, that can mean paying €80–€90 of arrears plus €80 for 3 months of new tax — just to end up in the same position you would have been in by filing RF150 in time. The arrears trap typically costs Irish drivers €100–€200per missed deadline.
Motor tax expires on the last day of the stated month. A reliable approach: set one reminder 3 weeks out (so you have time to act) and one reminder on the 1st of the expiry month (so you know the filing window has opened). Miss the end of the expiry month and the arrears trap slams shut.
Penalties for driving an untaxed car
| Stage | Penalty | Penalty points? |
|---|---|---|
| Fixed Charge Notice issued | €60 | None on the FCN |
| Unpaid after 28 days | €240 (4× increase) | None |
| Unpaid after 56 days — court summons | Up to €1,000 fine on conviction + costs | Up to 5 penalty points on conviction |
| Repeat offending | Vehicle can be seized and impounded | Penalty points on conviction |
Contrary to common belief, the initial Fixed Charge Notice for driving without motor tax does not carry penalty points. Points (up to 5) only apply if the case progresses to court conviction. However, the escalation from €60 to €240 to court summons happens quickly — always pay or appeal within 28 days.
See our penalty points guidefor the full list of motoring offences that do carry FCN points.
Getting the car back on the road
Ending an off-road declaration is as simple as taxing the vehicle. You can do this at any point:
- Online: motortax.ie with your PIN — takes about 5 minutes
- In person: your local Motor Tax Office
- By post: complete the RF100/RF100A renewal form and post to your Motor Tax Office
The motor tax starts from the first day of the month you pay for. You can't get a refund for unused months of the off-road declaration — but there's no penalty for ending it early either.
See our motor tax rates guide for current rates by engine size and CO2 band.
Off-road vs scrapping — which one fits your situation?
| Off-road declaration (RF150) | Scrapping (Certificate of Destruction) | |
|---|---|---|
| When | Intending to bring the car back on the road | Vehicle is at end of life; won't be returning to the road |
| Ownership | Retained — you're still the registered owner | Ends — vehicle deregistered on NVDF |
| Future motor tax | Resumes when you bring the car back | Permanently ended |
| Paperwork | RF150 — online or Motor Tax Office | Delivery to ATF, receive Certificate of Destruction |
| Cost | Free | Free (often get €50–€300 for scrap metal) |
If a car has repeatedly failed NCT, is on permanent non-use, or is beyond economical repair, scrapping at an Authorised Treatment Facility is usually the cleaner answer. See our how to scrap a car in Ireland guide for the full ATF process.
