Luxembourg tax office simulator: find the right office in just a few clicks
Not sure which tax office to contact for your tax return in Luxembourg? Don't panic: our tax office simulator allows you to quickly and easily find the relevant office based on your place of residence.
Why is it important to identify your tax office?
Each taxpayer is assigned to a specific tax office based on their municipality of residence. This office processes your income tax return, sends tax notifications and responds to any questions or complaints you may have. If there is an error, your correspondence may be processed late or not at all.
How does our simulator work?
Our online tool is simple, fast and free. All you need to do is:
- enter your country and postcode,
- and the simulator immediately displays the relevant tax office, along with its address, telephone number and email address.
No more lengthy searches on the Direct Tax Administration (ACD) website: in just a few seconds, you can find all the information you need to contact the right department.
Where should I send my tax forms?
Depending on your situation, you must submit one of the following forms:
- Form 100 (personal income tax return) must be sent to your local tax office, depending on where you live.
- Form 163 (annual statement) must be sent to the RTS office.
You should not send both forms: only the one that applies to your situation should be submitted.
Frequently asked questions:
Do cross-border workers also have a designated tax office?
Yes, even if you do not live in Luxembourg, you are assigned to a specific office.
Do I still need to send my declaration to the specified office?
Yes, you must send your documents by post to the relevant tax office.
What should I do if I change my address?
Moving? You must notify the authorities and check if your tax office changes too. Use our simulator to find out.
Save time with our tax office simulator and make sure you submit your tax return to the right place.
