How the Basel-Stadt business tax process works

1. Discovery call

A 20-minute call to understand your legal structure, business model, locations of operations and existing accounting setup. We clarify whether your profile fits our SME, corporate and cross-border focus.

Who we typically work with in Basel-Stadt

Owner-managed GmbHs and AGs with growing domestic and international business
Swiss subsidiaries of foreign groups requiring local accounting and tax compliance
Holding, IP and financing companies in canton Basel-Stadt
Tech, services and trading companies with platform, SaaS or cross-border VAT issues
Companies with key executives or shareholders who also use our private client services

Very small, purely domestic bookkeeping-only mandates without profit, capital tax or VAT complexity are generally outside our core focus and often better served by local mass-market providers.
