About

“Our Story”

Solutions 4 Expats BV was established in April 2004 to provide high-quality US tax services for US citizens living and working outside the US as well as foreign nationals living and working within the US.

Since then our vision has continued to expand in pace with the unique needs of our international clients and the dynamic financial environments in which they live. With a generous knowledge of the special concerns and challenges facing US citizens living abroad as well as foreign nationals within the US, we are positioned to offer detailed, expert services and support ranging from basic US tax returns to more complex relationships.
