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.

5 stars – highly recommended. From the initial meeting to the final submission of my tax return, everything was completed within one week. The entire process was handled online and was incredibly smooth thanks to their app, which made document sharing and communication very easy. My contact person was professional, knowledgeable, responsive, and genuinely pleasant to work with. I felt confident throughout the whole process that my tax return was in good hands. On top of that, the final price was very fair for the quality and speed of service delivered. I’m extremely satisfied with their work and will definitely use their services again.

Questions still lingering?
We’re here with the answers you need.

Here’s what people often want to know before getting started with FIN.

How often do we review my financial situation?

We recommend reviewing your financial situation at least once a year or whenever there are significant changes in your life. However, we can tailor the frequency of reviews to your preferences and needs.

Do you also help with budgeting and financial organization?
