Family allowance in Luxembourg: 2026 amounts and payment

Key figures

The amount has been indexed since 1 October 2021: it follows the index brackets, like salaries. The allowance is not taxable in Luxembourg (Article 115, No. 5 of the Income Tax Act). For three children aged 2, 7 and 13, a family receives 315.04 + 338.85 + 374.48 = €1,028.37 per month.

Children whose entitlement started before 1 August 2016, in a family of at least two children, keep a transitional scheme. Their amount depends on the number of children in the family group, for example €353.34 per child in a group of 2 children and €409.40 in a group of 3, excluding age supplements. Check your CAE statement.

Payment dates in 2026

This is the date the payment is sent to your bank. Allow one to two more days, sometimes longer for a foreign bank.

Entitlement starts in the month of birth. If you move to Luxembourg, it starts on the 1st of the month following your arrival declaration at the commune.

Cross-border worker: who pays first?

You are entitled to it if you work in Luxembourg and are registered with the CCSS (Centre commun de la sécurité sociale). Your children must live in the European Union or in a country linked to Luxembourg by an agreement.

When two countries could pay, the European rule decides: work takes priority over residence.

• Your spouse doesn't work: Luxembourg pays everything, every month.
• Your spouse works or receives unemployment benefit in your country: that country pays first. Luxembourg pays a differential supplement, the gap between its amounts and what you already receive, calculated child by child.
• Your spouse works in a third country: the country that pays the most pays everything.

In France, with only one child over 3, the CAF pays nothing: so Luxembourg pays every month.

The supplement for January to June arrives at the earliest at the end of July, the one for July to December at the earliest at the end of January.

A worked example

Camille, 34, lives in Thionville and works in Luxembourg. Marc, her husband, is an employee in Metz. They have Léo, 4, and Inès, 8.

• Luxembourg amount: 315.04 + 338.85 = €653.89 per month.
• Marc works in France, so the CAF pays first: €152.25 per month for two children since 1 April 2026, if the household's 2024 income does not exceed €79,980.
• Luxembourg supplement: 653.89 − 152.25 = €501.64 per month.
• From July to December 2026: 501.64 × 6 = €3,009.84, paid in one go, at the earliest at the end of January 2027.

Above the French ceiling, the CAF pays less and the supplement increases accordingly. The CAE sets the exact calculation, taking into account other French benefits of the same nature. The school start allowance paid by the CAF, for example, can temporarily reduce the supplement.

At 18: what changes

The allowance stops in the month of the 18th birthday. It continues until age 25 for:

• secondary education attended in person, at least 24 hours per week (evening and distance courses excluded);
• an apprenticeship paid less than the SSM (minimum social wage).

Higher education does not give entitlement. An income at least equal to the SSM for 4 months out of 12 (paid internship or job) also stops the payment.

The CAE writes to you two months before the 18th birthday, then every summer. Since July 2026, its letter contains a QR code linking to an online procedure. Without a reply, payment stops on 31 July.
