GST Compliance & Returns

Ongoing GST compliance centres on the periodic return obligations under the Central Goods and Services Tax (CGST) Act, 2017.

Section 37 — GSTR-1: Every registered person must furnish details of outward supplies in FORM GSTR-1, as prescribed under Rule 59 of the CGST Rules, 2017, by the 11th of the month following the tax period (for monthly filers).

Section 39 — GSTR-3B: A summary return of outward and inward supplies, ITC availed, and tax payable/paid must be filed under Section 39, in the manner prescribed by Rule 61, either monthly or — for eligible small taxpayers — quarterly under the QRMP (Quarterly Return, Monthly Payment) scheme notified under Rule 61A, which permits taxpayers with aggregate turnover up to ₹5 crore in the preceding financial year to file GSTR-3B quarterly while paying tax monthly.

Section 44 — GSTR-9: An annual return in FORM GSTR-9 consolidating the year's outward/inward supplies and ITC, as prescribed under Rule 80.

Return-locking advisories: GSTN Advisory No. 606 introduced hard-locking of the auto-populated tax liability in GSTR-3B (sourced from GSTR-1/GSTR-1A/IFF), preventing manual edits to auto-drafted figures; GSTN Advisory No. 624 extended this to auto-locking of ITC as auto-populated in GSTR-3B from GSTR-2B, restricting manual overrides. Both advisories require discrepancies to be corrected at source — via GSTR-1A (amendment) or ITC reversal/reclaim in GSTR-3B — rather than through direct edits at the summary-return stage.

Late filing of any of these returns attracts late fees under Section 47 and interest on delayed tax payment under Section 50 of the CGST Act.

GST compliance and returns is the monthly machinery of a registered business's GST life — the outward supply statement, the monthly return and the input tax credit that together keep the business compliant. Under the CGST Act 2017, the outward supplies are reported in GSTR-1 under Section 37, the monthly return in GSTR-3B under Section 39, the credit position is reconciled with the auto-generated GSTR-2B under Section 38, and the annual return follows under Section 44. The late fee of Section 47 and the interest of Section 50 are the price of the calendar.

The compliance is a system, not a form. The invoices drive the outward supplies, the purchases drive the credit, and the returns must reconcile with both — the GSTR-1 with the invoices, the GSTR-3B with the GSTR-1 and the GSTR-2B, the credit with the eligible position. The businesses that run the system find the month-end is a review; those that run the forms find every month is a scramble and every difference a future finding.

The cost of a broken return cycle is the known arithmetic: the late fee under Section 47 for returns filed late, the interest under Section 50 for tax paid late, the credit that was never reconciled with the GSTR-2B, and the mismatches that surface at the audit as demand seeds. Each is a leak the system prevents.

This service is for registered businesses that want their GST returns run as a system. We manage the GSTR-1 and GSTR-3B cycle under Sections 37 and 39, reconcile the credit with the GSTR-2B under Section 38, handle the payments and the late-fee positions, prepare the annual return under Section 44, and keep the compliance calendar running so the GST life is routine.
