Accounting and auditing are the professional service pair where a foreign investor in Vietnam is simultaneously a mandatory client and a conditional provider. Every foreign-invested enterprise in Vietnam falls under mandatory annual financial statement audit — a market served by audit firms holding the Ministry of Finances eligibility certificate, with international firms present through branches and foreign-invested companies under the Independent Audit Laws own conditions. This article runs both directions: conditions to provide the service, and the FDI enterprises duties when using it.
Conditions for founding a foreign-invested accounting or audit firm
The two services carry two separate frames. Accounting services under the Law on Accounting 88/2015/QH13: an accounting service enterprise must register for accounting services business upon meeting practitioner conditions — holding practising accountants with registered practice certificates in the enterprise at the statutory number and structure, and client accounting services may only be performed by qualified accounting service enterprises or households. Audit services under the Law on Independent Audit 67/2011/QH12 are stricter: an audit firm must hold a certificate of eligibility for audit services business issued by the Ministry of Finance, meeting structural conditions on practising auditors inside the firm (the classic requirement being at least five practising auditors belonging to the firm, with key leadership positions held by practising auditors), capital and professional liability insurance. Foreign investors join in the forms the Independent Audit Law permits: founding a foreign-invested audit firm, a branch of a foreign audit firm in Vietnam, and joint ventures, with added conditions on the foreign audit firms standing, and foreign auditors practising in Vietnam must hold a Vietnamese auditor certificate or be recognised under the laws mechanism.
How FDI enterprises must have their financial statements audited
The reverse direction is the clients duty: a foreign-invested enterprise falls under mandatory audit, and its annual financial statements must be audited by an eligible audit firm in Vietnam before filing with the tax authority, investment registration authority and banks within accounting and tax law deadlines. The auditor and audit firm must be independent of the client under professional ethics standards: not auditing an entity for which they also provided accounting and bookkeeping services in the same period within statutory limits, and signing-auditor rotation applies for public-interest clients as prescribed. For multinational groups, the Vietnam audit is usually a component audit inside the groups consolidated audit: the Vietnamese firm of the same global network performs under the group auditors instructions, and the Vietnamese-standards audit report simultaneously serves domestic filing duties. FDI enterprises should lock the audit calendar and prepare files from the fourth quarter, because Vietnams audit season concentrates heavily into the following first quarter and qualified firms are fully booked.
Professional risks and standards for foreign accounting and audit firms
Three professional disciplines decide a firms licence and reputation. One is independence and conflicts: the firm must run a network-wide conflict check before accepting clients, because a prohibited advisory relationship at any office destroys audit eligibility. Two is quality control under Vietnamese auditing standards and international network standards simultaneously, with working papers that withstand Ministry of Finance inspection and review by the home regulators of listed clients. Three is the service boundary: an audit firm is restricted in providing certain non-audit services to its own audit clients (bookkeeping in the same period, major valuations, outsourced internal audit within statutory limits), so an international firm must design the service firewall between its audit arm and its tax and deals arms from contract structure upward. A firm entering by acquiring a domestic audit firm must diligence both the client portfolio and the sellers quality files, because professional liability from past audits follows the acquired legal person.
Conclusion and Next Steps
Foreign accounting and audit services in Vietnam are an open door with a hard frame: a Ministry of Finance certificate, an in-country practising auditor team and independence discipline to standard. An international firm respecting that frame gains a mandatory FDI client market growing with investment flows; and every FDI enterprise should treat the annual audit as a governance cycle starting in the fourth quarter, not a filing procedure in March.
