Refund procedure changes: new rules allow exclusion of deficiency period, withdrawal of refund applications, and release of withheld refunds. Amendments exclude the period between filing a refund claim and communication of deficiencies from the two year limitation, allow withdrawal of refund applications before provisional or final sanction by filing FORM GST RFD 01W, and mandate crediting back any electronic ledger debits on such withdrawal. They further revise withholding and release mechanics by substituting FORM GST RFD 07 with a two part form (Part A for withholding with reasons and Part B for release), and permit officers to release withheld refunds when withholding conditions no longer exist.
