Whether you were born here or just arrived, the observation is the same: Luxembourg's administrative system could be so much clearer. We created trigger for that.

Tax returns, tax classes, deductions, CNS, CCSS, housing, transport... Luxembourg has a rich but dense system. And whether you're a cross-border worker, an expat, or a native Luxembourger, the same questions always come up: where do I start? Am I missing something? What is this form?
trigger exists to answer these questions. Clearly, simply, without unnecessary jargon. We don't replace a tax advisor or a lawyer, but we help you understand the lay of the land before you dive in.
Guides that explain procedures like a well-informed friend would.
Tools to take back control: personal finance, salary, housing, employment rights.
Know what to expect on your journey, step by step.
trigger informs and guides you, but never gives personalized advice. For a specific situation, a tax advisor or a professional can provide you with tailored support.

We don't come from the same place. We're not the same age. We don't have the same background. But we all found ourselves at the same point: facing a Luxembourg administrative system that could be so much clearer.
One of us has lived in Luxembourg for decades and still navigates forms that change every year. Another arrived from France and discovered that even with a high level of motivation, understanding his tax form was a real challenge. The two youngest, born here, figured that if even they found it opaque, there was a real problem.
We met, compared our respective struggles, and realized that we weren't the problem. Access to information was.
To build the tool we all wish we'd had. Not just another institutional website, but a true companion that speaks your language.
trigger is growing, one guide and one simulator at a time. The ambition: to cover much more than just taxes.


Italo-Luxembourgish, retired. Decades in the country's tax system. The living memory of everything that has changed, and everything that hasn't.

Young Luxembourger, marketer and TikToker. If a topic can't be explained in 30 seconds, we're explaining it wrong. The one who makes sure trigger speaks your language.

Young Luxembourger, developer and architect of trigger. The one who turns an idea scribbled on a napkin into something that actually works.

Arrived from France, went through all the stages: registration, affiliation, declaration, confusion. Turned his struggles into guides.

trigger, that’s us: different backgrounds, one shared desire to make things simpler. For you, for us, for everyone who lives in Luxembourg and deserves to understand how it all works.
