Vietnamese household businesses’ income may still be identified when bank transfers have no note
From July 1, 2026, Vietnam will classify household businesses by tax risk using data analysis. Tax authorities say leaving bank transfers without notes or using vague descriptions does not reduce tax obligations. Discrepancies between declared revenue and transaction flows may prompt further checks.
From July 1, 2026, Vietnam’s tax administration of household businesses will enter a phase of risk classification based on data analysis. Tax Office No. 12 in Thanh Hoa province said tax authorities will assess each household business’s risk level using electronic invoices, transaction flows and past compliance records, then determine the appropriate level of oversight.

Risk classification is based on whether different data sources are consistent, including declared revenue, bank transaction flows, issued invoices, tax payment records and business registration information. Discrepancies between declared revenue and transaction flows, or frequent changes to business information that are not registered, may be risk signals requiring verification. A risk classification is neither a finding of wrongdoing nor grounds for a penalty; taxpayers retain the right to explain, provide additional documentation and appeal.
Under the tax rules described in the article, turnover subject to value-added tax for household businesses and individual business operators covers all revenue from selling goods and providing services to which they are entitled, whether or not payment has been received. Accepting only cash, leaving bank transfers without notes, or vaguely labeling payments as loans or coffee expenses does not reduce tax obligations. Such practices may instead raise suspicions of concealed revenue.
The head of the Hanoi Tax Department said tax authorities still have data on sellers and transaction flows even when bank transfers have no notes. The Hanoi Tax Department said it also uses tax databases and information exchanged with other departments to identify revenue-related risks, rather than relying solely on transfer records. Regional Tax Subdepartment I warned that sellers who charge buyers extra for paying by bank transfer may also be suspected of violating the law.
