Cross-border from Germany: Trier and the Moselle valley
53,400 German residents commute. The A64 from Trier, the Wasserbillig bridge, and since 2024 the same 34 remote days.
Taxation on the German side
Salary taxed in Luxembourg, counted in Germany via the Progressionsvorbehalt. The remote-work threshold rose from 19 to 34 days on 1 January 2024, aligning Germany with France and Belgium. Watch days worked outside Luxembourg for any other reason (travel, training): they count against the same quota.
Trier, the corridor's real city
With 110,000 inhabitants, a university and a listed historic centre, Trier is the zone's only real German city. Line 30 (~50 min via Wasserbillig) and the A64 link it to Kirchberg; the bottleneck is the border bridge and the Trier bypass. Konz and Saarburg drop rents a notch along the Saar.
Perl and the Schengen road
Facing Schengen, Perl literally lets you cross the Moselle on foot. The commute then flips to Luxembourg's A13 via Frisange — often more fluid than the A64. It's the German corridor's "wine-country" option, with a German supermarket (and its prices) in every village.
