Luxembourg employers: telework days for staff living in France, Belgium or Germany
In short: BorderDay covers all three Luxembourg residence routes in one company account: France→LU, Belgium→LU and Germany→LU. Each has a 34-day tax tolerance counter (with pack-specific part-time rules) plus the shared social-security framework under 50%. Day types only — no location tracking. Not tax or legal advice.
FAQ
Can one company account cover staff from France, Belgium and Germany?
Yes. Each employee picks France→LU, Belgium→LU or Germany→LU. HR sees all three on the same dashboard.
Is the 34-day limit the same on every route?
The headline tolerance is 34 days on all three. Part-time reduction applies on France→LU only; Belgium→LU and Germany→LU keep 34 days without that reduction, per the cited official notes.
What about social security versus tax?
They are separate counters. Tax uses the 34-day tolerance; social security uses the framework percentage bands (25% / under 50% / 50%+), including CCSS Luxembourg guidance for employers.
Do you use GPS?
No. Only day types and an optional overnight-away mark. Never device coordinates.
Is BorderDay legal or tax advice?
No. It tracks days against public thresholds linked here and in the app. Confirm filings with your adviser or the competent administration.
