This tax organizer covers only the most common situations. We kindly request you to provide us with any other information that is not already mentioned in this organizer and that you would consider relevant for your 2021 tax return in respect to your personal tax situation. Please contact us if you have any doubts whether it might be relevant or not. We cannot be considered liable if you provide us with inaccurate and/or incomplete data.
Considering a large number of tax returns we have to file each year, we prefer to communicate everything through email or by phone. It is possible you will not hear from us for several weeks after you send in the requested information, as we work on a first-in-first-out basis with an ultimate deadline of 25.11.2022.
If you would still like to have a meeting to discuss your tax filing, please send us a separate email, so we can contact you to schedule a meeting.
