Cross-Border Tax Guide
United States–Switzerland Tax
U.S.–Swiss tax issues often span two very different systems. Residency, employment, investments, Swiss pension arrangements, companies, real estate, estates and annual U.S. reporting have to be coordinated across both jurisdictions.
Overview
One cross-border situation, two tax systems
U.S. persons living in Switzerland may remain subject to U.S. tax and reporting obligations while becoming taxable in Switzerland under federal, cantonal and communal rules.
The result is rarely a matter of filing two separate returns independently. Foreign tax credits, treaty provisions, social-security rules, pension classification, investment reporting and entity treatment should be coordinated from the outset.
