Why file a tax return, even if it is not mandatory?

Filing a tax return in Luxembourg is often beneficial, even if in your situation, it is not necessarily mandatory to do so. 

Is it mandatory to file a tax return in Luxembourg?

Yes, if…
Your household receives for example: 
  • an annual taxable income exceeding 100.000€.
  • several incomes (e.g. 2 different salaries)
  • income not taxed at source (e.g. rental income)

No, but...
Even if it is not mandatory, it can allow you to benefit from a considerable tax refund, because you can deduct some expenses on your return and so benefit from a tax refund!
