Divorce and separation tax in Luxembourg: what changes
The tax treatment of a separation depends on its nature, its date and the legal conditions. Household income, children and maintenance payments must be examined separately. A change of address alone does not allow you to draw conclusions about all the tax consequences.

Qualify the situation
Distinguish de facto separation, legally organised separation and divorce, then check the provisions applicable to the year. The transitional tax class rules are conditional; it would be inaccurate to announce tax class 2 for three years without examining those conditions.
Letters from the tax authorities must be compared with the decisions and dates. The withholding applied by an employer does not confirm all your annual entitlements.
Children and shared custody
The child's household, the family allowances and the exercise of parental authority may play a role in the tax relief rules. A custody agreement is important but does not on its own settle all the tax benefits.
Fictitious example: both parents bear costs and take turns looking after the child. Each benefit must be allocated according to its own regime; ceilings and expenses are not automatically doubled.
Maintenance payments
Maintenance paid to a former spouse must be distinguished from maintenance paid for a child. Depending on the situation, the treatment may fall under special expenses or extraordinary expenses, with different conditions and effects for the persons concerned.
Keep the decision, the relevant agreements and proof of the payments. An amount promised but not paid, or an expense already taken into account elsewhere, must not be deducted a second time.
