taxx.lu offers a range of deals and rates:

The "Standard" rate :

In the event of an error in your tax assessment, our team can also draft a letter of appeal to be sent to your tax office.

The "Premium" rate :

With our "Premium" package, you will have the same advantages as our "Plus" offer, with the added option of scheduling a telephone appointment for any further questions, as well as the possibility for our team to print out your tax return and its attachments and send them to you at home.

With our ‘Platinum’ package, we will give you a personalised quote based on your individual situation (starting at €290). You can then submit your tax certificates via our online platform, and our team will take care of completing your tax return in its entirety.
