The firm employs 100+ specialists — including 19 tax advisors (Steuerberater), 10 auditors (Wirtschaftsprüfer), and 22 certified balance sheet accountants — and serves a diversified client base spanning freelancers, SMBs, mid-market companies, and large corporations, with sector depth in medical practitioners and gastronomy/hospitality. Its core offerings cover tax advisory and planning (including international tax), statutory and consolidated audits under UGB and IFRS, ongoing financial accounting, payroll processing, and financial/M&A advisory, recognized by ten consecutive 'Steuerberater des Jahres' awards from 2016 to 2025.

The firm's technology stack is built on BMD software for core tax and accounting workflows, complemented by the proprietary rtg.connect client communication and document-exchange platform, paperless digital accounting processes, and 14+ online calculators. AI-driven automation was formally recognized by the 2024 'Digital Hero | KI-automatisierte Kanzlei' award from Finmatics. RTG is part of the MOORE Global international network of ~300 firms across 112 countries and 30,000+ professionals, enabling cross-border audit and tax engagements.

RTG generates revenue primarily through recurring retainer arrangements for ongoing tax advisory, financial bookkeeping, and payroll services, supplemented by project-based fees for audit, transaction advisory, M&A support, and restructuring engagements. Distribution is direct through the three Austrian offices plus the rtg.connect digital portal, with marketing driven by the firm's award reputation, sector-specific tax news content, and SEO-targeted calculators. The firm is partnership-owned with no disclosed external institutional investors; growth has been executed through organic expansion and a documented pattern of practice acquisitions (Riezler 2011, Fritz 2013, Zettinig 2016) and subsidiary consolidation (Kleinwalsertal merger, January 2025).
