AI Summary

Refund of excess GST interest: claim under Rule 89 or adjust against future interest payments per CBIC guidance.
Where interest on late-filed GSTR-3B has been paid twice-once responding to a departmental notice and again via the return filing system-the taxpayer may claim recovery of the excess by following the refund procedure under Rule 89 of the CGST Rules and the procedural guidance in CBIC Circular No.125/44/2019-GST. If the amount is significant, file a refund application; for minor amounts consider adjusting against future interest liabilities, retaining payment records and notices to substantiate the claim.
