The reorganization of administrative units and implementation of the two-tier local government model from 01/07/2025 have resulted in changes to the tax administration structure in Hanoi. Instead of the former district-level tax team system, the Capital’s Tax Authority has been reorganized into 25 Tax Offices responsible for the new ward and commune areas.
This change is significant for tax administration activities and requires businesses, household businesses, and individuals fulfilling tax obligations in the city to update their information.
1. How has Hanoi’s tax authority system changed following the merger?
From 01/07/2025, the Tax sector officially began operating under a new organizational model, in line with the implementation of the two-tier local government system.
Under Decision No. 1378/QĐ-CT dated 30/06/2025 of the Tax Department, Hanoi’s Tax Authority system is organized into 25 Tax Offices. Numbered from Tax Office 1 to Tax Office 25, these units are under the Hanoi Tax Authority and perform tax administration duties in their assigned ward and commune areas.
Notably, the management scope of each Tax Office is no longer defined solely by the boundaries of former districts. One unit may oversee multiple new wards and communes, while areas of certain former districts may be divided among different Tax Offices.
The reorganization aims to streamline the structure, enhance consistency in administration, and ensure that tax operations are not interrupted when administrative boundaries change.

Note: The above list shows management areas under Decision No. 1378/QĐ-CT dated 30/06/2025. When carrying out actual procedures, taxpayers should recheck their directly managing unit through the electronic tax system or official information from the Hanoi Tax Authority.
3. Changes businesses should note when carrying out tax procedures
The change in the organizational structure of tax authorities not only concerns state administration but also directly affects businesses’ administrative procedures.
To avoid confusion when filing declarations and working with tax authorities, businesses should note the following:
First, update the directly managing tax authority.
As management areas are divided according to new wards and communes, businesses should not assume that the tax authority responsible for them remains the same unit that managed them under the former district boundaries. They should check their directly managing tax authority through the electronic tax system.
Second, review the company address information.
Following the administrative reorganization, ward and commune names in a company’s registered office address may change. Businesses should review information on documents, invoices, and transaction records to ensure consistency. A change in administrative boundaries does not mean that businesses must automatically amend all legal documents.
Third, identify the correct location for submitting documents.
When in-person contact is required, businesses should check the office address or one-stop service department of the responsible Tax Office. Addresses of former district tax departments in old documents should not be used without verification.
Fourth, prioritize electronic transaction channels.
Electronic tax services enable businesses to complete many procedures, including filing declarations, paying taxes, looking up tax obligations, and receiving notifications, without visiting a tax authority in person. This approach is also consistent with the direction of modernizing tax administration.
4. Where can businesses look up tax authority information?
To avoid using outdated information, businesses and taxpayers can proactively look up information through the following channels:
Tax sector web portal: https://www.gdt.gov.vn/ – provides updated information, policies, and guidance related to tax administration.
Electronic Tax system: https://thuedientu.gdt.gov.vn/ – supports businesses in completing tax transactions online.
Hanoi Tax Authority information portal: Follow announcements on organizational structure, addresses, and contact information for subordinate tax units.
Decision No. 1378/QĐ-CT dated 30/06/2025: This document specifies the names, headquarters, and management areas of the Tax Offices.
Verifying information through official channels will help businesses identify the correct managing unit and reduce errors while fulfilling tax obligations.
5. Conclusion
The reorganization of Hanoi’s tax authority system into 25 Tax Offices is one of the key changes associated with the reorganization of administrative units and implementation of the two-tier local government model.
For the business community, understanding the management area of each Tax Office, updating administrative information, and proactively using electronic tax services will make procedures more convenient and accurate.
This is also essential information for businesses looking for, leasing, or relocating office space in Hanoi, particularly when carrying out procedures related to business registration, registered office addresses, and tax obligations at a new location.
