I have worked with Geoffrey Archimi for my taxes in the past three years and he has being extremely helpful. As an expat who has had different Swiss permits in the past years and have moved from one canton to another one while working on another canton, my taxes have been extremely complicated. However, Geoffrey has provided me guidance and support to get everything in order. Honestly, I would have been so lost without him. So, I highly recommend working with him.
I worked with him mostly in Spanish, but his English and French are excellent. He has also helped me with my taxes on the German side of Switzerland.
