Cross-border from Belgium: the calmest corridor
53,750 Belgians commute. A predictable E411, the Arlon train, well-oiled taxation: often the best overall compromise.
Taxation: the Belgian framework
Same treaty logic: taxed in Luxembourg, exempt (with progression reserve) in Belgium, contributions and CNS in Luxembourg. Belgium also applies the 34-day remote-work tolerance. Belgian quirk: communes levy additional percentages — the exemption largely neutralises them, but check your case if you have other Belgian income.
Arlon, the obvious rear base
A county town with schools, a hospital and a direct train (~38 min, half-hourly at peak), Arlon concentrates most of what a cross-border household needs. The E411 towards Gasperich slows between Sterpenich and the interchange, but is nothing like the French A31. Aubange, Messancy and Athus offer the same equation more affordably, ten minutes from Pétange and Rodange.
Further out: the Gaume and Ardennes
Virton and Bastogne offer houses with gardens under €9.5/m² and genuine rural quality of life — but 45 minutes to an hour's drive with no serious rail alternative. It's the "mostly remote" choice: formidable at 2 office days a week, painful at 5.
