If you are registered under 'All Taxable Services - Other than in Negative List' – Do get your Registration amended
THE ACES website informs, "Assessees who got registration on or after 01.07.2012 with 'All Taxable Services - Other than in the Negative List' or those who have amended their Registration by adding the description 'Other than in the Negative List', are required to file amendment to their Registration online and give the relevant description(s) of Taxable Service(s) available in the drop-down list in the online amendment form."
This was already informed by the CBEC in Circular No. , dated 20.11.2012 as, "Registrations obtained under the positive list approach continue to be valid. New taxpayers can obtain registrations by selecting the relevant description/s from among the list of 120 descriptions of services given in the Annexure. Where registrations have been obtained under the description 'All Taxable Services', the taxpayer should file amendment application online in ACES and opt for relevant description/s from the list of 120 descriptions of services given in the Annexure."
