When you indicate your address on taxx.lu the system automatically determines your tax office and it will be visible in the "Tax situation" form, in the "Result" form after your payment and also in the tax return itself.

If you want to choose another tax office, you can simply change it in the "Tax situation" form.

For form 100 you will be administered to a tax office and for form 163 to an RTS office.
