Is it mandatory to file a tax return in Luxembourg ?

There are different criteria that make the tax return mandatory. For example, if your household has an annual taxable income exceeding €100.000 or if you receive several incomes in the same household, such as two different salaries. The same applies, of course, to households that have received income that was not taxed at source: if you rent an apartment to a third party, for example, and you have received rent, then this income has not been taxed. You must therefore declare this income on your tax return.
