In practice

Who has to file a tax return in Luxembourg?
1. A resident taxpayer is required to file a tax return when:
- wage income/pension income exceeds:
     - the 100,000 EUR/year (if tax class 1 and a tax deduction form)
     - 36,000 EUR/year (if tax class 2 or tax class 1 and several withholding tax forms)
     - the 30,000 EUR/year (if tax class 1A)
- for other incomes, it is necessary to study case by case
2. A non-resident employee may file a tax return if he or she receives more than 50% of professional income in Luxembourg.
A non-resident employee may be treated as a resident and must file a tax return if:
     - Belgian resident: 50% or more of the household's professional income is taxable in Luxembourg
     - French resident: 90% or more of the household's worldwide income is taxable in Luxembourg (if married, it is sufficient for one of the taxpayers to satisfy this condition)
     - French resident: the annual net income not taxable in Luxembourg does not exceed EUR 13000 per year

What is the deadline for filing a tax return?
The tax administration advises to file this return before March 31 N+1.
