Vietnam’s new accounting regulation, Circular 99/2025/TT-BTC, marks a shift toward greater financial transparency, raising the bar for how enterprises, both local and foreign-invested, account, report and govern their finances from 1 January 2026.
For companies used to a more prescriptive, rules-based system, this move toward a principle-based approach may create uncertainty around internal controls, documentation and reporting expectations. The new framework introduces greater flexibility in areas such as accounting systems, functional currency and consolidation, while placing more responsibility on internal governance and risk management.
In this video, Ms. Thy Le, Manager of Accounting & Tax at Acclime Vietnam, breaks down what’s changing and outlines a practical roadmap for transitioning from Circular 200.
