<h1>Ladakh and Daman & Diu taxpayers must use new GSTINs for TRAN-1 & TRAN-2 forms after regional reorganization.</h1> Taxpayers from Ladakh and the former Daman and Diu region, affected by the reorganization of Jammu Kashmir and the merger of Union territories, have been issued new GSTINs. They are advised to file or revise TRAN-1 and TRAN-2 forms using these new GSTINs, not the old ones. Tax administrations in these regions should assist taxpayers by linking old and revised TRAN-1 forms with the new GSTINs during processing.
