taxx.lu, what is it?
taxx.lu is a website that allows you to do your income tax return in Luxembourg easily and quickly.
Without knowledge of taxation
Taxx.lu decrypts your income tax return and translates complicated tax terms into understandable language without being a tax expert. The aim of taxx.lu is to enable everyone to file their income tax return and take full advantage of all the tax benefits offered by the legislation.
Through a simple and comprehensive questionnaire
To make your income tax return, taxx.lu allows you to avoid pages and pages of forms which are incomprehensible and complicated. A simple questionnaire guides you quickly through the different steps. For each question, taxx.lu provides you with help for even more clarity.
Which automatically adapts to your individual situation
The Luxembourg income tax return is no less than 16 pages long. But most people must fill only 3 to 4 pages, since the others do not concern them. taxx.lu only asks you for the information that concerns you, while automatically adapting itself to your personal situation. If you do not own your home for example, then taxx.lu does not ask you for information. This is how taxx.lu allows you to file your tax return in Luxembourg as fast as possible.
With the necessary proofs added automatically through your smartphone
The tax authorities ask you to attach a number of certificates (e.g. pay slips, insurance certificates, home purchase savings plans, etc. ...) to your income tax return. taxx.lu makes your job as easy as possible. With your smartphone (iPhone, Android ...), you can take photos of your certificates and upload them on taxx.lu. This is also possible with PDF files. We then generate a single PDF file containing your income tax return and your annexes.
Automatic control of all deductible limits
taxx.lu automatically checks if you have forgotten any possible deduction, in order to be sure not to pay more taxes than necessary. If you have nothing to deduct, then taxx.lu records all deductible packages automatically.
By giving customized tips in relation to your individual situation
Throughout the process, taxx.lu analyzes your tax situation and offers tips that help you save taxes. These tips are tailored to your personal situation so that you can take full advantage of all the existing tax benefits.
Ready to be sent to the tax authorities
For just EUR 30, taxx.lu generates your income tax return in PDF format. In this PDF file, you will find on one side your income tax return (official form 100 or form 163R, depending on your personal situation), and on the other side all the annexes (certificates) added using your smartphone. All you have to do is print the PDF file, sign it and send it to your tax office.

taxx.lu provides you with customized tips in relation to your individual situation. No matter if you are single or married, if you have children, or if you own your home, taxx.lu allows you to complete your income tax return as efficiently as possible and save taxes.
