# GST returns and ongoing compliance in Bengaluru > Monthly, quarterly and annual GST compliance for Bengaluru businesses: GSTR-1, GSTR-3B, GSTR-9 and 9C, ITC reconciliation with GSTR-2B, e-invoicing and e-way bills, and a compliance calendar that keeps notices away. Marvel Consultants manages the rhythm. Source: https://www.marvelconsultants.co.in/business/gst-returns-compliance/ · Organisation: Marvel Consultants, Bengaluru · Phone: +91 91875 98642 · WhatsApp: https://wa.me/919187598642 · Last reviewed: 2026-08-29 Most GST notices are born in a return: an ITC claim that GSTR-2B did not support, a GSTR-1 that did not match 3B, an annual return filed from memory. Compliance is a monthly discipline, not a year-end task. Regular taxpayers file GSTR-1 (outward supplies) and GSTR-3B (summary return with tax payment) monthly — or quarterly under the QRMP scheme for smaller taxpayers — and the annual GSTR-9, with GSTR-9C reconciliation above the turnover limit. Input tax credit is now effectively limited to what appears in GSTR-2B, so reconciliation with suppliers is where compliance is won or lost. ## Who this is for - Businesses without an in-house GST specialist - Finance teams that want a second pair of eyes on ITC and reconciliation - Businesses with multiple GSTINs or high invoice volumes - Companies that have fallen behind on returns and need to catch up correctly - Firms subject to e-invoicing or with heavy e-way bill movement ## What Marvel does - Monthly/quarterly preparation and filing of GSTR-1 and GSTR-3B from your books, with review of classification and rates - ITC reconciliation against GSTR-2B every period; follow-up list of suppliers whose invoices are missing or mismatched - Reverse-charge tracking, credit/debit note handling and amendments in later periods - Annual return GSTR-9 and reconciliation statement GSTR-9C readiness (with your auditor where applicable) - e-invoicing and e-way bill applicability, set-up and exception handling - A compliance calendar with due dates, interest/late-fee exposure and a monthly status note to management ## Documents and information usually required - Sales and purchase registers (accounting software export) - GST portal access or downloaded GSTR-2B/2A - Bank statements for reconciliation of tax payments - Previous returns and any notices received - E-invoice/e-way bill data where applicable ## Step-by-step process 1. **Onboarding review** — We reconcile returns filed to date with the books and GSTR-2B, and list what can be corrected in the next return. 2. **Monthly cycle** — Data by an agreed date → reconciliation and queries → draft return for approval → filing and payment before the due date. 3. **Quarter and year-end** — ITC review, amendments window, annual return and 9C preparation. 4. **Reporting** — A one-page monthly note: filed, paid, ITC position, supplier defaults, upcoming risks. ## Timeline and fees Fixed monthly fee based on GSTIN count and invoice volume, agreed after the onboarding review. Late fees and interest are statutory and depend on your filing history; we show the exposure before filing overdue returns. > **Not sure this is the right service?** Send us the situation in a couple of lines.

It reduces filings but not the need for monthly reconciliation. **Q: Can I claim ITC on an invoice that is not in my GSTR-2B?** A: As the law now stands, credit is restricted to what is reflected in GSTR-2B. If your supplier has not filed, the practical remedy is to get them to file and claim in the period it appears — not to claim it anyway and explain later. **Q: We have not filed for several months. What happens?** A: Late fees accrue per return, interest on unpaid tax, and after a continuous default the registration can be cancelled suo motu. Returns must be filed in sequence. We compute the exposure, file in order and, where appropriate, apply for revocation. **Q: Do I need to visit your office to start?** A: No. Most matters start with a call or WhatsApp and photographs of your documents. We meet at our Yeshwanthpur office or at the property when a physical inspection, signature or original document is needed. **Q: How are your fees structured?** A: A fixed professional fee agreed before work starts, quoted after a free first assessment of your documents. Government fees, stamp duty and statutory charges are separate and paid to the authority. We do not quote a headline price for complex matters because the work depends on what the records show. --- Contact: Sanjay +91 91875 98642 · Kiran +91 96635 38037 · info@marvelconsultants.co.in · 17/3, Community Hall Road, Ashokapuram, Yeshwanthpur Industrial Suburb, Bengaluru 560022 Disclaimer: Marvel Consultants is a private firm, not a government body.
