Deadlines for the tax declaration 2023 in Luxembourg: Do not miss important due dates
The deadline for the tax declaration in Luxembourg for the year 2023 is on the 31st of December 2024. Make sure to respect this due date in order to avoid penalties.
A Single Deadline for all Taxpayers
In contrary to previous years during which different due dates would apply, for the fiscal year of 2023, the Luxembourgish government simplified the process by establishing one single deadline date: the 31st of December 2024. This means that all taxpayers are able to submit their tax declaration only until this date, no matter their situation.
Why is Respecting this Deadline is Crucial?
Avoiding Penalties: If you do not submit your tax declaration before the due date, you risk having to pay late fees/delay charges. The tax administration may also apply interests on due taxes.
Avoiding Legal Issues: Not respecting tax obligations could result in legal complications, such as prosecutions, depending on the gravity of the delay.
Anticipate Corrections: Submitting your declaration before the due date allows you to make corrections of possible mistakes and to respond quickly to every request for supplementary information by the tax administration.
