Service tax exemption for security services to diplomatic missions removes tax liability for specified foreign missions. Exemption of service tax is granted for security agencies supplying security of any property or person to diplomatic missions or members holding diplomatic status of the countries listed in the Schedule, under section 93 of the Finance Act, 1994, thereby exempting such taxable services from service tax under section 66; the exemption was notified and later amended to add a listed mission, and was subsequently rescinded by a later notification.
