Frequently Asked Questions
The questions most people ask before getting started.
Could filing get me a refund?
Often, yes. If more tax was withheld from your salary or pension than you finally owe — common for cross-border workers, married couples and anyone with deductible expenses — filing the return is how you get it back. I calculate your exact result before anything is submitted, so you know your number in advance.
When is the deadline to file?
The standard deadline for the Luxembourg income tax return is 31 December of the following year — for example, the return for 2025 can be filed until 31 December 2026. Filing earlier means any refund arrives earlier.
Do I have to file a return at all?
Some situations make filing mandatory; in many others it is voluntary but worthwhile. Describe your situation in the form below and I will tell you what applies as part of the preparation.
What documents will you need?
Typically your annual salary or pension certificates, statements for deductible items such as mortgage interest or insurance, and any rental or business records. You receive a short checklist tailored to your situation — most people gather everything in one evening.
How long does it take?
Once your documents are complete, preparation is usually finished within a few business days. You review the draft and the exact final numbers before anything is filed.
Is this tax advice?
No — and that is deliberate. I provide administrative preparation and processing of your return: collecting the right documents, completing everything correctly and calculating the result with the official tools. For fiscal advisory questions, a licensed tax advisor is the right address.
What happens to my data?
Your documents are used only to prepare your return, are handled confidentially and are never shared with third parties. See the privacy notice for details.
Online filing is free — why pay someone?
Filing yourself is free, and for some people it is the right choice. What you pay for here is the time, the knowledge of the forms and the checking: a person prepares your return, includes what applies to your situation and shows you the result before anything is filed — in your language.
What if I have more documents?
Each package includes the documents of a typical return for each person: your salary or pension certificate, your insurance and loan certificates and the other usual items listed under Prices. Some people have several salary certificates or many more receipts; each document above the allowance is billed as an extra document. You get the full price before I start, and couples taxed jointly get the allowance for each person.
