Trust accounting services

When a trust becomes relevant for US tax purposes Swiss trustees often find it difficult to find a US tax service provider that can provide the required accounting services needed to prepare the necessary US tax calculations without the fear of their client’s confidential data being sent abroad.

We work with US and local attorneys to determine the trust’s accounting requirements and assist in compiling special-purpose financial statements under a US tax accounting framework.
