Frequently asked questions
Do I have to file a tax return in Luxembourg?
It depends on your income and family situation. Even when it is not mandatory, filing often lets you recover tax. We check your case during our first conversation.
Cross-border worker: should I opt to be taxed as a resident?
This option can give access to deductions and a more favourable rate, under certain conditions. We compare both scenarios before choosing.
When must the tax return be filed?
Deadlines depend on your situation (mandatory tax return or refund request through the annual adjustment). We tell you the exact deadlines from our first conversation. Don’t wait: a refund not claimed in time is lost for good.
Can you handle previous years?
Yes, within the legal time limits. Send us your past documents and we will see what can still be recovered.
