Transitional provisions for existing taxable persons :
Existing taxpayers will have to migrate to GST.
Existing taxable persons having valid PAN number will be given provisional registration certificate. It will be valid for six months. They will submit required details. Then final registration certificate under GST will be issued. If required details are not furnished within specified time, registration will be cancelled – section 139(1) of CGST Act.
All persons who are presently registered or have license under existing law (like State Vat, Central Excise, service tax) shall be liable to be registered under GST – section 22(2) of CGST Act.
Thus, if a registered person does not intend to continue under GST, he should immediately apply for cancellation of his existing registration.
