What Flachgau Treuhand GmbH does

Flachgau Treuhand GmbH Steuerberatung und Wirtschaftsprüfung is an Austrian tax and business advisory firm headquartered in Straßwalchen near Salzburg, operating continuously since 1971 under a WTBG 2017 license with membership in the Kammer der Steuerberater und Wirtschaftsprüfer. The firm is solely owned and managed by Ing. Mag. iur. Michael Thalhauser, MBA, with a five-person professional team, and operates from two Straßwalchen sites — Schwemmstraße 1 (headquarters for reception, management, consulting, financial statements, payroll, and administration) and Schwemmstraße 14 (bookkeeping). Its geographic focus is North Salzburg and West Upper Austria.

The firm delivers a full-service professional mandate organized around seven core competency areas: Beratung (consulting on tax, social security, economic, and customs law, plus transactions, restructuring, and succession); Abschluss/Erklärung (annual and consolidated financial statements under national standards and IFRS); Controlling/Kostenrechnung; Personal (payroll and labor-law consulting, including international deployment); Bücher (double-entry bookkeeping and VAT advisory); Gutachten/Prüfung (valuations, due diligence, and agreed-upon procedures); and Verteidigung (defense in tax and social security proceedings up to the Constitutional Court and EU Court of Justice). Online-Anwendungen provide digital client access to accounting and payroll workflows as a digital add-on.

Revenue is generated through retainer-based advisory mandates and project-based engagements governed by the Wirtschaftstreuhandberufsgesetz 2017 and standard professional fee regulations. Customer segments are diversified across primary KMU/SME and private-client mandates, with secondary association (Vereine) and public-sector clients. Client acquisition is referral-driven and supported by a monthly topical newsletter, an Empfehlung contact form, and a complimentary one-hour initial consultation. Distribution is direct through firm professionals, with no third-party channels or resellers.
