What RSM Hungary does

RSM Hungary is a Budapest-based professional services firm and independent member of the RSM Global network, providing tax advisory, audit and risk advisory, accounting and bookkeeping outsourcing, payroll and HR, legal services, ESG/sustainability, customs, and transaction advisory to medium-sized and large enterprises as well as international corporate groups operating in Hungary. The firm employs approximately 200 multidisciplinary professionals including chartered accountants, tax advisors, auditors, payroll specialists, and attorneys, structured across multiple operating entities — the main advisory arm (RSM Hungary Zrt.), a separately registered audit entity (RSM Hungary Könyvvizsgáló Zrt., Hungarian Chamber of Auditors registration 004443), and an associated law firm (RSM Szűcs & Partnerei Ügyvédi Iroda). Revenue is generated through bespoke, quote-based professional services engagements typically structured as multi-year contracts, with go-to-market combining direct enterprise sales, thought-leadership content (blog, webinars, podcasts, NIS2 Calculator), and inbound referrals from the RSM Global network spanning 120 countries and 65,000 professionals.

The firm's technology stack centers on proprietary digital tools layered on top of a traditional professional services model. Connectax is a digital tax platform providing eÁFA-compatible VAT declaration preparation with machine-to-machine capabilities, integrating with major ERPs (SAP, SAP B1, Navision, Oracle, Axapta, Microsoft Dynamics 365). EthiCom is a proprietary digital whistleblowing system developed for compliance with Hungary's Whistleblower Protection Act (Act XXV of 2023) and ESG governance requirements. RSM Cloud provides real-time, cloud-based accounting with customizable workflows and approval controls. Specialized service desks target Asian companies entering Hungary (Asian Business Desk), automotive suppliers (TISAX), critical infrastructure (NIS2), and regulated sectors, while the firm has launched compliance advisory for the EU AI Act and ISO/IEC 42001 AI management systems. A March 2025 merger with Credit Management Group's ESG unit created RSM Hungary ESG Solution, consolidating sustainability advisory under one umbrella and reinforcing the firm's positioning as a regulatory-compliance-led professional services franchise in the Hungarian and CEE market.
