Selling your car in Luxembourg: a step-by-step guide

To sell your car privately in Luxembourg, prepare the vehicle and its documents, set a price in line with the market, publish a detailed advert, then arrange a test drive and payment securely. Next, sign an invoice with the buyer and notify the SNCA that the vehicle is being taken off the road within 5 working days and remove the number plates.

This guide follows the actual sequence of a sale and is based on the procedures published by Guichet.lu and the SNCA.

What are the steps involved in selling your car in Luxembourg?

Selling a second-hand car between private individuals in Luxembourg involves seven steps, from preparing the vehicle to the procedures following the signing of the contract.

1. Prepare the car and gather your documents.
2. Set a price that is in line with similar listings.
3. Post a full advert with high-quality photos.
4. Secure contacts, trials and payments.
5. Sign an invoice with the buyer.
6. Notify the SNCA that the vehicle has been taken off the road within 5 working days.
7. Remove the number plates, notify your insurer and claim a refund of the tax.

Steps 1 to 4 are up to you and affect the final price. Steps 5 to 7 set out the seller’s obligations and the measures that protect them after the sale.

Step 1: Prepare the car and gather the necessary documents

A clean, well-maintained car with all its documents in order sells more quickly, as the buyer can assess its condition without having to guess. Preparations therefore begin before the first photo is taken.

As for the vehicle itself, a thorough clean inside and out can make all the difference to the first impression. Fix any minor, inexpensive faults, such as a burnt-out bulb or a fluid level that needs topping up. For more extensive repairs, weigh up the cost against the actual value they add.

As regards documents, start gathering the paperwork the buyer will ask for straight away:

• the registration certificate, Part 1 (grey) and Part 2 (yellow); ;
• the roadworthiness certificate; ;
• the service record and repair invoices; ;
• spare keys and the vehicle manuals.

A comprehensive maintenance history reassures the buyer and justifies a higher price during negotiations.

Step 2: Set a price in line with the Luxembourg market

You can work out the right selling price by comparing your car with similar models currently for sale in Luxembourg. The most important factors are the make, model, year, mileage, engine type, specifications and service history.

To arrive at a realistic range, Compare second-hand cars for sale in Luxembourg by filtering by model, year, mileage and fuel type. Focus on the adverts that most closely match your vehicle rather than a broad average.

Allow for a reasonable margin for negotiation, as most buyers will ask for one. A price that is too high will put potential buyers off; a price that is too low will arouse suspicion. Buyers in the Greater Region often compare several listings: a price justified by the property’s upkeep and fixtures and fittings stands up better.

Step 3: Post a comprehensive advert with high-quality photos

An effective advert provides the buyer with all the relevant information before they make their first enquiry. The title should specify the make, model, engine type and year, for example «Volkswagen Golf 1.5 TSI 2021».

In the description, state the mileage, the type of gearbox, the fuel type, the main features, the number of previous owners and the date of the last MOT. Also mention any known faults: an honest advert attracts serious buyers and minimises disputes after the sale.

Photos often make all the difference between two adverts at the same price. Take photos of the car when it is clean, in daylight, against a clear background. Show the exterior from several angles, the interior, the odometer, the condition of the tyres and, where applicable, any faults mentioned.

Fill in all the fields provided by the platform. On Luxauto, buyers filter by make, model, budget, mileage, location, fuel type and seller type: leaving a field blank may exclude your advert from a search.

Step 4: Secure contacts, trial and payment

A smooth sale begins right from the very first exchange with the buyer, well before you receive payment. Respond promptly to messages and ask a few questions over the phone to identify buyers who are genuinely interested.

For the test drive, choose a busy location and a time during the day. Before the test drive, check the buyer’s driving licence and accompany them on the journey. Also check with your insurer that cover is in place for a third party to drive the vehicle.

When it comes to payment, do not hand over the keys or documents until the amount has been credited to your account. A screenshot of a bank transfer does not prove that the money has arrived. Be wary of offers to pay more than the asking price or to use an intermediary abroad.

Step 5: Sign the invoice with the buyer

The invoice, also known as a sales contract, is essential when selling a vehicle in Luxembourg. According to Guichet.lu, it must unequivocally identify the vehicle, the seller and the buyer, and verify the identity of the vehicle’s registered keeper or owner.

In practice, the invoice states:

• the make, model and chassis number of the vehicle, as well as its registration number; ;
• the mileage at the time of sale; ;
• the surname, first name, address and signature of the seller and the buyer; ;
• the date of the sale and the price.

Both the seller and the buyer must attach a copy of their identity card. The seller must be listed as the last official owner. The buyer retains the original invoice, which is essential for registering the vehicle in their name.

The Automobile Club of Luxembourg (ACL) offers sales contract templates in several languages, which is useful when the buyer does not speak French.

Step 6: Notify the SNCA that the vehicle has been taken off the road

The seller must notify the National Motor Vehicle Registration Authority (SNCA) that the vehicle has been taken off the road within 5 working days of the sale. This notification severs the link between the seller and the vehicle.

There are three ways to make the declaration:

• online, via the service De-registration of a vehicle on MyGuichet.lu; ;
• by registered post addressed to the SNCA, PO Box 23, L-5201 Sandweiler; ;
• without an appointment, at the reception desk of an SNCA centre: Fridhaff, Sandweiler or Esch-sur-Alzette.

The file includes the form for declaring a vehicle as withdrawn from circulation Parts 1 and 2 of the registration certificate, completed and signed, together with proof of identity. The SNCA then sends an acknowledgement of receipt confirming that the vehicle has been taken off the road.

Once the car has been taken off the road, it cannot be driven again until it has been re-registered. You should therefore agree in advance with the buyer on how they will collect the vehicle.

Step 7: Remove the number plates, notify the insurer and claim back the tax

At the time of sale, the seller must remove the vehicle’s number plates. This obligation is one of the steps to be taken by the seller, as described by Guichet.lu.

As soon as the vehicle is taken off the road, notify your insurer and return the Green Card or insurance certificate to them. The policy will then be cancelled, with a possible refund of the remaining annual premium, or transferred to another vehicle in accordance with the terms agreed with the insurer.

If the tax disc has not expired, you can claim a partial refund of the road vehicle tax. This refund is only available once the vehicle has been deregistered with the SNCA, and only if the amount exceeds €1. Please return the tax disc to the Central Treasury of the Customs and Excise Administration, together with the IBAN of a bank account in Luxembourg, no later than 60 days after the expiry date. The refund is calculated on a pro rata basis according to the number of days remaining and rounded down to the nearest euro.

What difference does a sale to a non-resident buyer make?

A non-resident buyer who wishes to register the car in their own country requires an export certificate issued by the SNCA. This is a common situation in Luxembourg, where many buyers live in France, Belgium or Germany.

The seller may apply to the SNCA for the export certificate and provide it to the buyer. Guichet.lu indicates a fee of €19.80, payable at the SNCA counter or by bank transfer, quoting the registration number in the payment reference.

If the seller has not requested it, the non-resident buyer may obtain it themselves after the vehicle has been taken off the road, providing the original invoice or proof of ownership. In all cases, the seller remains obliged to report the sale to the SNCA and to remove the number plates.

Frequently Asked Questions

Can someone else handle the sale on my behalf?

Yes, a third party may submit the declaration of de-registration on behalf of the registered owner, the owner or the keeper of the vehicle. They must provide the SNCA with a written authorisation signed by that person; Guichet.lu offers a Sample power of attorney for dealing with the SNCA. All documents must show the name of the holder, owner or possessor, not that of the authorised representative. The seller, for their part, must be listed as the last official owner on the invoice.

Can a garage deregister my vehicle on my behalf?

Yes, garages and businesses authorised to trade in road vehicles may report the de-registration of vehicles on behalf of their customers, in accordance with Guichet.lu. This is a common option when a garage takes back the car when you buy another vehicle. The deadline remains 5 working days after the transfer. Ask the garage for a copy of the SNCA’s acknowledgement of receipt to keep as proof that the link to the vehicle has indeed been cancelled.

What happens to a personalised number plate once you’ve sold your car?

A personalised registration number remains automatically reserved in the seller’s name for 12 months after the vehicle is taken off the road. The seller can then use it for their next car. If the number is not used to register a vehicle within this period, it becomes available again for other applications. As with a standard number plate, the seller must remove the number plates from the vehicle being sold.

Do you need a valid MOT to sell your car in Luxembourg?

The sales procedures described by Guichet.lu do not mention any roadworthiness test that the seller is required to provide. However, a buyer registering a second-hand car in Luxembourg must present a valid roadworthiness certificate for vehicles subject to periodic roadworthiness testing (Steps for buyers on Guichet.lu). A car sold with a recent MOT certificate is therefore easier for the buyer to register, which makes it easier to sell and helps maintain the asking price.

Is it better to sell your car to a private individual or trade it in at a garage?

Selling to a private individual generally fetches a better price, whilst trading it in at a garage saves time. According to the ACL, the amount offered by a garage when trading in a car is often lower than the price you would get by selling it yourself. Selling privately, on the other hand, involves managing the advert, viewings, test drives and the administrative procedures. The right choice depends on how much time you have available and the difference between the trade-in offer and market prices.
