From 2026, many business households are concerned about whether it is mandatory to open bank accounts in the name of business households if revenue is below 500 million VND/year when the tax management mechanism shifts to actual revenue.
According to the general guidance from current regulations, business households with revenue below 500 million VND/year are not required to open private bank accounts in the name of business households. However, business households still have to fulfill the obligation to notify tax authorities of bank accounts or electronic wallets used for production and business activities as prescribed.
This regulation aims to serve the management of business cash flow data in the context of tax authorities switching to a management method based on actual revenue from 2026.
Business households must notify business accounts before April 20, 2026
According to Article 4 of Circular 18/2026/TT-BTC, business households that have paid tax according to the khoán method or declared in 2025 and have revenue from 500 million VND or less must send a Notice of account number/electronic wallet number according to Form 01/BK-STK no later than April 20, 2026.
Meanwhile:
- Business households with revenue over 500 million VND send account notifications attached to the first tax return of 2026;
- New business households starting operations send account notifications along with tax declaration documents or initial revenue notifications;
- In case of changing bank accounts or e-wallets used for business activities, it is necessary to continue to notify the tax authority according to regulations.
Thus, even though it is not mandatory to open a separate account, business households still have to fulfill the obligation to notify the account to serve business operations on time as prescribed.
Not every personal account must be notified to the tax authorities
According to the guidance in form 01/BK-STK issued with Circular 18/2026/TT-BTC, business households only need to declare bank accounts or e-wallets used for production and business activities, not all unrelated personal accounts.
In case there are multiple accounts used to receive sales money, business households must fully declare each corresponding account.
In addition, if the account has been closed or information has been changed, business households must still update the status with the tax authority according to current tax management regulations.
