GST Return Filing Services in India

GST Return Filing is the periodic compliance obligation under the CGST Act, 2017 through which every registered taxpayer reports their outward supplies, inward supplies, input tax credit, and tax payable / paid to the Government — through a prescribed set of electronic forms filed on the GST portal. Unlike a one-time registration event, GST returns are a continuous month-on-month, quarter-on-quarter, and year-on-year activity — and the accuracy, timing, and reconciliation of each return directly drives the taxpayer's working capital, input credit, and exposure to interest, late fees, and assessments.

The GST return ecosystem is wide — GSTR-1 for outward supplies, GSTR-3B for summary tax payment, GSTR-2B as the static ITC statement, GSTR-9 and GSTR-9C as annual return and reconciliation, CMP-08 for composition dealers, GSTR-4 for composition annual return, GSTR-5 and GSTR-5A for non-resident and OIDAR suppliers, GSTR-6 for Input Service Distributors, GSTR-7 for TDS deductors, GSTR-8 for e-commerce operators, and ITC-04 for job work. Each return has its own due date, format, schema, and downstream impact on customers, vendors, and the taxpayer's own refund and assessment position.

We offer end-to-end GST Return Filing Services across India — for proprietors, professionals, MSMEs, private limited companies, LLPs, exporters, e-commerce sellers, manufacturers, and large corporates — covering monthly and quarterly return preparation, GSTR-2B reconciliation, tax computation, challan generation, portal filing, annual return and audit, and complete representation during assessments. Our goal is simple — file every return on time, maximise eligible input credit, minimise interest and late fees, and keep your GSTIN in perfect standing year after year.

FAQs on GST Return Filing in India

How many GST returns does a regular taxpayer need to file?
A regular GST-registered taxpayer typically files GSTR-1 and GSTR-3B on a monthly or quarterly basis, along with GSTR-9 annually and GSTR-9C where applicable. For most mid-sized businesses, this works out to 25 returns per GSTIN per year — 12 GSTR-1s, 12 GSTR-3Bs, and one annual return. Under the QRMP scheme, small taxpayers with aggregate turnover up to ₹5 crore may file GSTR-1 and GSTR-3B quarterly, with monthly tax payment through Form PMT-06. We map the optimal filing frequency for each client based on turnover, customer profile, and cash-flow considerations.
What is the QRMP scheme and who is eligible?
QRMP stands for Quarterly Return Monthly Payment — a scheme allowing GST taxpayers with aggregate annual turnover up to ₹5 crore to file GSTR-1 and GSTR-3B on a quarterly basis while paying tax on a monthly basis. Monthly tax is paid through a simple challan in Form PMT-06, while invoices can be optionally uploaded each month using the Invoice Furnishing Facility (IFF) so that customers can claim ITC without waiting for the quarter-end GSTR-1. The scheme is optional and the choice can be revisited each quarter. We help clients decide whether QRMP is cash-flow-friendly or whether regular monthly filing is a better fit.
What are the due dates for the main GST returns?
For monthly filers, GSTR-1 is generally due on the 11th of the following month, while GSTR-3B is due on the 20th of the following month. Under QRMP, quarterly GSTR-1 and GSTR-3B due dates fall on the 13th and 22nd / 24th of the month following the quarter, state-wise. CMP-08 for composition dealers is due on the 18th of the month after the quarter, and GSTR-4 by 30 June. GSTR-9 and GSTR-9C for the financial year are generally due by 31 December of the next financial year. We maintain a client-wise compliance calendar to track every due date across multiple GSTINs.
What happens if GST returns are filed late?
Late filing of GST returns attracts two distinct charges — late fee under Section 47 of the CGST Act (typically a per-day late fee capped at a prescribed maximum, split between CGST and SGST) and interest under Section 50 at 18% per annum on the net tax liability paid in cash. Persistent delays can also lead to suspension of the GSTIN, blocking of e-way bill generation, and denial of ITC to customers. Our compliance workflow is built to file every return well within due dates — but if there is legacy non-compliance, we help regularise it in a structured, cost-minimised way.
Can a taxpayer with no transactions skip GST return filing?
No. As long as the GSTIN is active, the taxpayer is required to file returns for every tax period, even if there are no transactions. In such cases, a nil return must be filed — which can often be done through the GST portal, or even through SMS for regular taxpayers with no outward or inward supplies in the period. Not filing nil returns is treated as non-filing and attracts the same late fee and suspension consequences. We track and file nil returns for dormant GSTINs so that the registration stays in good standing until a formal cancellation, if desired.
How important is GSTR-2B reconciliation in return filing?
GSTR-2B reconciliation is arguably the most important piece of modern GST return filing. Under Rule 36(4) and related provisions, input tax credit in GSTR-3B is linked to invoices appearing in GSTR-2B — if a vendor fails to file GSTR-1 or files late, the corresponding ITC may not be available to the recipient. Monthly reconciliation of GSTR-2B with the purchase register helps identify missing invoices, mismatches, and vendors who need follow-up well before the return is filed. We treat GSTR-2B reconciliation as a core deliverable of every monthly GST filing engagement, not an afterthought.
Which businesses need to file GSTR-9 and GSTR-9C?
GSTR-9 is the annual return and is mandatory for every regular taxpayer whose aggregate turnover during the financial year exceeds the prescribed threshold (currently ₹2 crore in most cases). GSTR-9C is a self-certified reconciliation statement between audited financial statements and GSTR-9, and is typically required from taxpayers whose aggregate turnover exceeds ₹5 crore. Casual taxable persons, NRTPs, ISDs, TDS / TCS deductors, and OIDAR providers are not required to file GSTR-9. We help clients determine applicability each year and build the reconciliation well before the annual due date.
Can GST returns be revised or corrected after filing?
GST law does not currently provide for a "revised" GSTR-3B. Errors in invoice data, tax, or ITC reported in earlier periods are corrected through amendments in subsequent-period returns — GSTR-1 has dedicated amendment Tables 9A, 9B, and 9C, while GSTR-3B adjustments are made within the editable fields of a later month along with any interest. The window for most corrections closes on 30 November of the next financial year or the date of filing GSTR-9, whichever is earlier. Our teams identify errors proactively through monthly reconciliation and correct them cleanly within the statutory window.
