The agency said April 23 it will introduce a “generative AI chatbot” service starting May 1, offering interactive, conversational guidance. The rollout expands AI-based assistance beyond value-added tax filings and year-end tax settlement to include comprehensive income tax and the earned income and child tax credits.
Through HomeTax and Mobile HomeTax, taxpayers will be able to ask in real time whether they need to file, how to file, and what requirements apply for deductions and tax relief during the filing process. With the addition of mobile access, users can receive help regardless of time and location.
The chatbot will generate answers based on consultation cases and filing manuals verified by the tax agency. The NTS said it will quickly reflect newly revised tax laws and administrative interpretations to provide information that is more accurate and consistent than general-purpose AI.
The agency said it has also applied safety measures, or guardrails, to block questions unrelated to tax law and prevent inaccurate responses. The chatbot screen will also provide practical resources, including sample return-writing cases, a tax credit simulation calculator and videos explaining electronic filing.
The NTS previously operated an AI chatbot in the VAT and year-end settlement areas in January and February. It said users increased by about 20% and the number of questions per user fell, indicating improved efficiency.
The agency said it will use the pilot to build AI consultation infrastructure and later develop tailored tax guidance linked to each taxpayer’s assessment information. Over the longer term, it plans to expand functions to include AI-assisted e-filing and an AI tax consultant to improve taxpayer convenience.
