Transitional credit verification: jurisdictional officers must verify TRAN-1/TRAN-2 claims and issue reasoned orders before ledger crediting. Verification of Transitional Credit filed/revised through TRAN-1/TRAN-2 must be performed by the jurisdictional central or state tax officer who shall commence verification upon availability of the form or receipt of a self-certified copy, coordinate with counterpart officers where both central and state components exist, follow principles of natural justice, obtain supporting records, consider counterpart verification reports and applicant submissions, and pass a reasoned order quantifying allowed credit and upload it to the common portal for crediting to the electronic credit ledger.
