Grant Thornton Switzerland

What Grant Thornton Switzerland does

Grant Thornton Switzerland/Liechtenstein is a privately held member firm of Grant Thornton International Ltd (GTIL) providing audit, tax, advisory, and outsourcing professional services to corporate, financial-services, and SME clients across Switzerland and Liechtenstein. The firm operates from four offices — Zurich (headquarters), Geneva and Buchs in Switzerland, and Schaan in Liechtenstein (ReviTrust Grant Thornton Services Establishment) — staffed by 240 employees including 27 partners, delivering services in German, French, and English under a partner-led engagement model.

The firm's service architecture spans four lines. Audit covers statutory, regulatory, and industry-specific financial statement audits. Tax spans corporate, individual, indirect/VAT, transfer pricing, and M&A tax. Advisory is the broadest line, comprising IT & Digitalisation (including SAP consulting, Cyber Security Health-Check, and CyberHunter), Forensic Services, a dedicated Regulatory & Compliance Financial Services practice (FINMA, FINIG, FIDLEG, AML/GwG, sanctions, FATCA) supported by the proprietary GTRegs monitoring tool, M&A/Transaction Services, Legal Services, Trust Services (notably Liechtenstein structures), Business Risk Services, and IFRS Services. Outsourcing delivers Abacus ERP support via the AbaWeb customer portal, plus accounting and payroll services, representing a recurring managed-services revenue stream.

The go-to-market relies on direct enterprise and mid-market engagement, RFP intake via the website, cross-border referrals from the GTIL network (now coordinated through the Grant Thornton Advisors LLC multinational platform joined in January 2025), and thought-leadership channels including LinkedIn, newsletters, YouTube employer branding, and the Finance Forum Liechtenstein event series. No pricing is publicly disclosed; fees are negotiated engagement by engagement. Customers are not named but span large corporations, FINMA-regulated financial institutions, family-owned businesses/SMEs, and international/multinational groups — with a recent strategic push into French-speaking Switzerland via the Baker Tilly Spiess SA acquisition and the 2026 expansion of the Regulatory & Compliance practice into Geneva.
