  • the Class 1 for singles;
  • the Class 1a for unmarried persons with children and individuals aged 65 at the beginning of a tax year;

Starting with 2018, married foreign citizens earning incomes in Luxembourg as non-residents will enter the Class 1 tax category. These can opt to be treated as Luxembourg residents and thus be taxed under the Class 2 bracket which implies a combined assessment for the levy of the income tax. Under this tax bracket, 90% of the entire income obtained by one of the spouses will be taxed in Luxembourg, or the income generated by one of the spouses abroad does not exceed 13,000 euros.
