Vanessa Leite
I am an expat living in Switzerland under B permit and was with doubts about having to file my taxes. I had a great experience talking to Marlon on a consultation call. I received advice and explanations about what situations would be an advantage to stop paying the withholding taxes and starting filing the taxes myself. I was full of uncertainty and now I feel with peace of mind.
