LEXPAT

This Basel-based firm bundles immigration, tax, and accounting services in one place, eliminating the usual hunt for separate advisors. They specialize in expat needs, so they already know the common pitfalls (tax canton vs. residence canton, social contributions, etc.).

Valuable if you prefer a single trusted contact for multiple tasks rather than juggling lawyers and accountants. Their integrated model also means better coordination between your visa status and your tax filing strategy.
