Don’t wait: The December 31 deadline is approaching for your tax return!

Don’t wait! The deadline for your 2024 tax return is December 31. With taxx.lu, you can easily prepare, submit, and have your return checked.

The year is already coming to an end, and with it, the December 31 deadline for submitting your 2024 tax return in Luxembourg. If you haven’t sent it yet, it’s high time to get started: November and December always fly by, between personal obligations, holiday preparations, and last-minute administrative tasks.

Attention: It’s the date of receipt that counts

A very important point to remember: it’s not the postal sending date that matters, but the date your tax office receives your return.
In other words, your return must arrive before December 31 at the competent office. A return mailed on December 31 but received in January will be considered late.

Don’t put it off until tomorrow

Don’t delay your tax return, because imagine you’ve misplaced an important document or still have a question for our team. In these cases, every day counts, and the last weeks of the year go by much faster than you think.
