GST Return Filing Online – Filed on Time by Expert CAs

It is the monthly, quarterly or annual submission of your sales, purchases, input tax credit and tax paid on the GST portal (gst.gov.in). Regular taxpayers file GSTR-1 and GSTR-3B, composition taxpayers file CMP-08 and GSTR-4, and most businesses above ₹2 crore turnover also file the annual return GSTR-9.

Monthly filers: GSTR-1 by the 11th and GSTR-3B by the 20th of the next month. QRMP filers: GSTR-1 by the 13th of the month after the quarter and GSTR-3B by the 22nd or 24th, depending on the state, with PMT-06 tax payments by the 25th for the first two months.

₹50 per day (CGST + SGST), or ₹20 per day for a nil return. The maximum is ₹500 for nil returns and ₹2,000, ₹5,000 or ₹10,000 for others, depending on whether turnover is up to ₹1.5 crore, ₹1.5–5 crore or above ₹5 crore. Interest at 18% a year is charged separately on tax paid late.

Yes. A registered business must file a nil GSTR-1 and GSTR-3B (or nil CMP-08 under composition) even when there is no business activity. Nil returns can also be filed by SMS. Not filing attracts a late fee of up to ₹500 per return and can lead to cancellation of registration. We file nil returns for ₹299 + GST per return, for monthly, quarterly and composition filers.

QRMP (Quarterly Return Monthly Payment) lets businesses with aggregate turnover up to ₹5 crore in the previous financial year file GSTR-1 and GSTR-3B quarterly, while paying tax monthly through PMT-06. B2B invoices for the first two months can be uploaded through IFF so buyers get credit on time.

Not the auto-filled tax liability. From the July 2025 tax period, the liability flowing from GSTR-1, GSTR-1A and IFF is locked in GSTR-3B, and from November 2025 Table 3.2 is also locked. Corrections must be made in GSTR-1A before filing GSTR-3B, or in a later GSTR-1. ITC in Table 4 is auto-filled from GSTR-2B but, as of October 2026, has not been hard-locked.

No. Since the July 2025 tax period, the GST portal does not allow GSTR-1, GSTR-3B, GSTR-4, GSTR-9 and certain other returns to be filed after three years from their due date. The tax liability still remains and can be demanded by the department, so pending returns should be filed as early as possible.

No. Under Notification 15/2025-Central Tax, filing GSTR-9 is optional for taxpayers with aggregate turnover up to ₹2 crore, from FY 2024-25 onwards. GSTR-9C is required only when turnover exceeds ₹5 crore. The due date for FY 2025-26 is 31 December 2026. Composition taxpayers file GSTR-4 instead, due by 30 June after the financial year (from FY 2024-25 onwards).

Supplier invoices appear in the Invoice Management System, where you accept, reject or keep them pending. GSTR-2B is generated on the 14th from these actions, and only ITC shown in GSTR-2B can be claimed in GSTR-3B. We match your purchase register with GSTR-2B every period and flag missing or wrong invoices.

Our professional fee is ₹399 + GST a month (or ₹3,999 + GST a year) for monthly filers, and ₹499 + GST a quarter (or ₹1,299 + GST a year) for QRMP and composition taxpayers. A nil return is ₹299 + GST per return and the GSTR-9 annual return is ₹2,000 + GST. There is no limit on the number of invoices, provided you share your GSTR-1 data duly filled in our prescribed format; Tally data is also accepted. If the data is not in the prescribed format, an additional fee applies for preparing it, and our team can help you prepare it in the prescribed format. There is no government fee for filing; late fee and interest apply only when a return or tax is late.

Entering a wrong GSTIN for a customer or supplier, reporting different sales in GSTR-1 and GSTR-3B, applying the wrong tax rate or HSN code, mixing up nil-rated, exempt and zero-rated supplies, missing reverse charge tax, claiming input tax credit that is not in GSTR-2B or is blocked, and skipping nil returns.

Nil-rated and exempt supplies carry no GST and are reported separately from taxable supplies. Zero-rated supplies are exports and supplies to SEZ units: they are taxable at a zero rate and input tax credit remains available. Reporting them under the wrong head misstates turnover and input tax credit.
