I needed to declare my taxes in Austria while having already left the country and living in Greece for a year. Simon helped me getting my tax refund and all necessary documents I needed. Great and prompt service!! Thank you so much Simon!

I worked as a seasonnaire in austria for 3 winters. Did not manage my taxreturn even though I speak quite a bit of german. Simon figured this out for me in no time and got me back way more than I expected. For anyone in the same situation as me; save you the trouble of trying this by yourself and just ask simon. He will get you back more than you could have by yourself so paying him for the job is basically a win-win. Thanks simon!

I warmly and highly recommend Mr. Bagnis as a best advisor to get your taxes done! From citizens of Austria, to people who are working seasons here and don’t speak a word of a German language! In shortest, quickest and most polite way he solved all my question and confusions! Thank you!

I contacted Simon via email to ask whether he can help me with my tax declarations for the last 3 years, 2 hours later he called me on the phone to collect all details and was ready to start. He prepared and submitted successfully my tax returns, which were processed by Finanzamt very quickly. He was extremely professional, friendly, helpful, focused on details. I can hardly imagine a better tax advisor for expats in Austria. He was always fast to reply to any questions and ready to do the research on what the best possible solution might be for any specific issues. I can highly recommended him and I am looking forward to work with him again in future! Thanks, Simon!
