Monthly GST return filing is not a data-entry exercise. The return cycle is a reconciliation sequence: GSTR-1 (outward supplies) must be filed before GSTR-3B (summary and payment), and the GSTR-2B (auto-drafted ITC) must be reconciled against the purchase register before the GSTR-3B ITC claim. A filing that skips the reconciliation creates a mismatch that surfaces in a scrutiny notice months later.
The Reconciliation Sequence
The taxpayer should close the sales register, issue credit notes for returns and discounts, reconcile the GSTR-1 with the e-invoice data (where applicable), file GSTR-1, download GSTR-2B, reconcile the purchase register with GSTR-2B, identify the eligible and ineligible ITC, compute the reversal under Rule 37/42/43 and Section 17(5), and file GSTR-3B with the reconciled figures. The sequence is not optional; it is the architecture of a defensible ITC claim.
The Late-Fee and Interest Exposure
A late GSTR-3B attracts late fee and interest. A late GSTR-1 delays the recipient’s GSTR-2B and creates a mismatch. The taxpayer should maintain a return calendar and should file before the due date rather than rely on the late-fee amnesty windows.
The Amendment Discipline
A GSTR-1 amendment or a credit note must be reflected in the subsequent return. An amendment that is not followed through creates a permanent mismatch. The taxpayer should track the amendment register and reconcile it with the GSTR-3B.
What the Consultant Does
The consultant manages the return calendar, the reconciliation, the filing and the mismatch response. The value is in the monthly discipline that keeps the ITC and turnover positions aligned.
