Questions regarding the "Tax situation" form on taxx.lu.
Is it possible to use taxx.lu if my household receives income from abroad?
Yes, it is. You have to go to the "Tax situation" form and then in the "The patricular situations in 2018" category you have to tick "Some or all of my income was generated outside of Luxembourg". You must then indicate for each income whether it comes from Luxembourg or from abroad.
What are tax advances?
Tax advances are quarterly advances that can be requested by Tax Authorities. If you are in this situation, enter the annual amount in field "I paid tax advances". Most people do not have to pay tax advances, so if this is your situation, leave the box blank. This is NOT the amount of tax withheld on your salary certificate!
Which is my tax office?
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.
