SIGTAX

SIGTAX serves entrepreneurs starting a company in Switzerland or relocating their business here. They handle the full lifecycle from corporate setup through ongoing accounting, bookkeeping, statutory audits, and tax filing, with particular experience in international structures and non-resident founders. Their team is accustomed to working across multiple jurisdictions and managing tax residency questions.

They're a good fit if you're forming a GmbH, AG, or sole proprietorship and need one partner to coordinate all compliance. International founders appreciate their multilingual support and experience with foreign tax treaty questions.
