Where should you live if you work in Luxembourg?
This page compares your estimated net pay, housing, commuting and telework exposure. Tax-treaty logic, social security and the recorded-cost budget stay clearly separate.
This is an estimate only. Your final outcome can differ based on your tax card, global rate, employer declarations and exact facts.
You can immediately see what belongs to treaty taxation, social security and the real monthly budget.
Your situation in 5 steps
The wizard stays simple and mobile. If your profile falls outside v1 scope, the page shows clearer review flags instead of pretending certainty.
V1 mainly covers private-sector employees with one employer.
Editable regional benchmarks.
All workdays outside Luxembourg can matter for treaty counting.
Real monthly out-of-pocket cost, separate from any tax deduction reference.
The output stays visible before any lead capture.

Need more than an estimate?
When the file gets more complex, WunnCheck can route you toward a human specialist instead of pretending the tool covers every edge case.
- Cross-border tax and payroll questions
- Relocation, mortgage or insurance handoff
- Public-sector, multistate or high-telework situations
- Support for people who want a second opinion before acting
The B2B framing and the proposed pilot are described on the employer page and the partner page.
How WunnCheck reads your scenario
The calculator keeps budget, cross-border work, and decision signals separate so you can see what needs a real-world check.
Budget layer
Compares estimated Luxembourg net pay, housing cost, commute cost, and monthly room left.
Cross-border work layer
Flags telework, treaty-day exposure, and social-security/A1 review points.
Decision layer
Highlights which scenario needs review. It does not make a final tax, legal, payroll, or mortgage decision.
Sources and assumptions
WunnCheck uses reviewed assumption files and source notes for Luxembourg tax/social contribution assumptions, housing averages, commute assumptions, telework/treaty/social-security framework assumptions, and the source registry. Official verification is still required before acting.
Example: lower rent can still mean a harder scenario
A France scenario may show lower housing cost but higher commute friction or telework review risk. WunnCheck separates those layers so the cheapest rent is not automatically treated as the best decision.
A quick read for HR teams
This card does not replace a legal audit or payroll review.
What the comparison shows
Treaty thresholds
Workdays outside Luxembourg are counted separately. WunnCheck shows whether you remain comfortably inside the line or whether a salary allocation outside Luxembourg becomes more likely.
Telework and A1
Tax-treaty logic and social-security logic are not the same. Telework can trigger A1 or multistate questions even without a treaty overrun.
Non-resident couples
Spouse income and assimilation can change the real outcome. The page flags that openly instead of hiding it.
Orientation, not advice
This version does not replace payroll, tax advisers or lawyers. It helps you arrive at the next conversation better prepared.
Sources and benchmarks
Tax and social-security rules come from official Luxembourg sources. Housing and commute benchmarks are clearly marked as editable editorial assumptions.
