A reporting entity is a banking company, financial institution, intermediary, or a person carrying on a designated business or profession, as defined and notified under the PMLA. The list has grown. Jewellers, real-estate agents, and specified professionals performing specified transactions have been brought in by stages. Whether a particular person in Gorakhpur or Ayodhya is in the net depends on the activity, not on the signboard. See AML / CFT obligations.
Answer
Who is a reporting entity under the PMLA?
Banks and many others — including certain professionals doing specified activities. The notification, not a guess, decides.
