What WTS does

WTS Advisory GmbH is a German professional services firm headquartered in Munich that delivers integrated tax, digital, financial advisory, and legal services to large enterprises and the Mittelstand. The firm operates from 11 German offices — Berlin, Düsseldorf, Frankfurt, Hamburg, Hannover, Köln, München, Nürnberg, Regensburg, Rosenheim, and Stuttgart — and acts as the coordination hub for the WTS Global network, which spans more than 100 countries. Core service lines include corporate and international tax, transfer pricing, VAT/indirect tax, M&A tax and tax controversy (Tax); accounting/reporting under HGB, IFRS and US-GAAP, ESG/CSRD advisory, IPO preparation, deal advisory, valuation and business partnering (Financial Advisory); SAP S/4HANA integration, tax technology, digital tax audit, data analytics and AI tools (Digital); and corporate, employment, data privacy and litigation support (Legal). The firm's deliberate avoidance of statutory audit work preserves FISG-compliant independence and eliminates conflicts of interest.

The underlying technology stack centers on the KI-gestützte WTS Platform, a cloud-based AI-supported hub that integrates tax compliance, reporting, and advisory modules. Around it sit proprietary digital products: plAIground (an AI playground for tax and advisory), the WTS Compliance Manager (income tax reporting and compliance), the CBAM Rechner (Carbon Border Adjustment Mechanism cost calculator), SAP RAM Tax Analytics and other SAP-integrated tax modules (withholding tax, VAT Reporting DRC), and topic-specific tax tech for VAT, transfer pricing, CbCR, and CESOP. Additional offerings include IFRS/US-GAAP conversion tooling (provided free to clients during conversion projects), consolidation workbooks, ESG data and CSRD/EU Taxonomy/VSME tooling, an ESG Discovery Phase workshop program, and ESEF/XBRL reporting services. The firm has tagged more than 1,000 financial statements for ESEF reporting and serves approximately 250 issuers through a 15+ person specialist team.

The business model is professional services revenue generated through project-based and multi-year consulting engagements, with pricing determined per engagement scope and complexity rather than through standardized tiers. Customer segments are organized primarily by enterprise tier (large corporations plus the German Mittelstand) and secondarily by vertical (Automotive, Banking & Capital Markets, Insurance, Real Estate). Distribution is direct, partner-led field sales across the 11 German offices, complemented by cross-border coordination through the WTS Global network. Marketing is content-led (WTS Journal, Tax Weekly newsletter, podcasts, KI Studie 2024, CSRD-Benchmarking studies, webinars, and a Knowledge Hub). WTS is a private firm (WTS Advisory GmbH) with one disclosed German subsidiary (DMS Management Services GmbH); no parent company or external investor is disclosed.
