GST Input Tax Credit Rules

This discussion addresses a query about claiming GST input tax credit for an invoice received pertaining to the financial year 2017-18. The user neither booked nor availed the credit for this invoice previously and is seeking advice on how to resolve this. Experts are asking for clarification on whether the invoice was just received or found, if payment has been made, and if it reflects in GSTR 2A, as claiming the credit now may be time-barred.
