The Hanoi Tax Department has implemented new digital communication tools to modernize tax administration and support taxpayers.

Initially, the department launched a centralized support hotline, developed with Viettel, to provide unified assistance across 33 support points in the city. This system uses a four-step management process to handle inquiries regarding tax policies, administrative procedures, and financial obligations for various entities.

Following this, the department expanded its digital outreach by introducing an SMS service under the sender name ‘THUE_HANOI’. This channel is specifically designed to deliver tax laws, compliance deadlines, and procedural guidance directly to individual business households to reduce administrative burdens.
