On 20 Shrawan 2063 (5 August 2006), a national assembly of registered auditors was held in Kathmandu to discuss the protection of professional rights, interests, and the development of auditors in Nepal. Recognizing the need for a unified platform to address these issues, the Auditors' Association of Nepal (AUDAN) was established. The assembly formally approved its formation to ensure a structured, institutional approach to promoting the rights and interests of auditors.

AUDAN was officially registered with the Labor and Employment Management Department on 8 Mangsir 2063 (24 November 2006) with the objective to promote the importance of accounting and auditing, protect and enhance the rights and interests of auditors, foster unity, goodwill, and understanding among accounting professionals, and ensure their accountability, discipline, and dedication toward their profession. Since then, it has been actively representing approximately 8,000 registered auditors across 63 districts under the motto, “Unity is Strength.”

As the only national professional organization for Registered Auditors in Nepal, AUDAN plays a crucial role in protecting auditors' rights, promoting organizational unity, enhancing professional competence, and contributing to the advancement of the accounting and auditing profession.

Before the rise of Chartered Accountants in Nepal, Registered Auditors were the backbone of the auditing profession, contributing significantly to the nation’s financial growth through their expertise in auditing, accounting, and related services. Despite the rapid increase in the number of Chartered Accountants, Registered Auditors continue to play a vital role in the profession. As a leading institution for Registered Auditors, AUDAN remains focused on professional development, safeguarding rights, and enhancing capabilities.

Today, AUDAN remains committed to empowering its members, addressing professional disparities, and fostering partnerships to achieve its goals for a stronger and more inclusive profession.
