Driving licence and vehicle registration: what changes when you move
An EU licence stays valid. The car, though, follows your residence — and the tax office takes an interest.
The licence
A licence issued by an EU or EEA state stays valid in Luxembourg with no compulsory exchange. Exchanging becomes useful in practice — for a renewal, a loss, or adding a category — and compulsory in some cases, notably after a court decision. Licences issued outside the EU are exchanged under bilateral agreements, sometimes with a test to retake; that is the point to check before moving, not after.
The car follows your residence
Becoming a Luxembourg resident obliges you to register your vehicle in Luxembourg, within a short window after settling. That means a roadworthiness test, proof of insurance and a visit to the SNCA. Conversely, a cross-border worker stays resident in their own country: they keep their national plates, insurance and roadworthiness test, even driving in Luxembourg every day.
The company car, the classic trap
A company car registered in Luxembourg and driven by a cross-border worker living abroad is a case neighbouring customs and tax authorities watch closely. Private use in the country of residence is regulated, and non-compliant use can trigger taxation there. Get the employer to confirm in writing what the contract allows, particularly for private journeys and use by a spouse.
Fuel, and why everyone tanks up here
Fuel duty is lower in Luxembourg than in its three neighbours, which explains the queues at border stations and a notable share of state revenue. For a cross-border worker, filling up at the end of the working day is a rational reflex — and one of the few lines where living far out costs less than you would think. The gap narrows with successive increases: worth checking rather than assuming.
