Taxpayer confidentiality bars officers and staff from transmitting identifiable taxpayer information or departmental data to public or commercial AI tools, third-party online platforms, external systems, browser extensions or personal accounts unless expressly authorised in writing. Permitted AI use is limited to generic, wholly hypothetical legal or procedural research and drafting support, with independent verification against primary sources. Officers remain personally responsible for disclosures made by themselves or persons acting under their control; breaches may lead to disciplinary action, criminal liability, data-protection consequences and challenges to affected proceedings. Notices and quasi-judicial orders must reflect the signing officer's independent assessment of facts and law, not unverified or mechanically adopted AI-generated content.
