Exchange of information enables transfer of foreseeably relevant tax data subject to confidentiality and domestic safeguards. Article 1 requires competent authorities to exchange information foreseeably relevant to the administration and enforcement of domestic tax laws, including determination, assessment, collection, recovery, enforcement of tax claims and investigation or prosecution of tax matters. Exchanged information must be treated as confidential under Article 8, and rights and safeguards available under the requested Party's laws or administrative practice remain applicable so long as they do not unduly prevent or delay effective exchange of information.
