Purpose of the FormThe officer flags a likely short-payment/refund-wrong claim before issuing a Show-Cause Notice (SCN).
Practical Tips Treat this as an early-warning: if you pay the tax/interest within 30 days, no SCN follows. File the payment through DRC-03 and keep the ARN on record. If you disagree, prepare reconciliations now; they become your annexures to the later DRC-06 reply.
