If I decide to complete a tax declaration in Luxembourg, will I have to pay money to the Luxembourg tax authorities?


If one's personal situation does not require completion of a tax declaration in Luxembourg (particularly annual taxable income < 100,000 EUR) and it is done spontaneously, the cross-border commuter should never pay money to the Luxembourg tax authorities. For cross-border commuters, the Luxembourg government will not exercise its right to recover the additional tax due.
