<h1>Exchange of information under DTAA: new overseas tax units to facilitate sharing while preserving treaty confidentiality.</h1> Income tax Overseas Units (ITOUs) have been established in Mauritius and Singapore and additional ITOUs created for several other missions to facilitate and expedite exchange of information under the Double Taxation Avoidance Agreements; information received remains governed by the confidentiality clause of each DTAA. Posting orders for officers have been issued, with actual relief pending finalization of terms by the Ministry of External Affairs, and inter departmental consultations continue to examine the need for more such units.
