What is GST Return Filing?

Every GST-registered business must file periodic returns on the GST portal declaring outward supplies, inward supplies, input tax credit (ITC) claimed and tax payable. The type and frequency of returns depend on your business turnover and the scheme you are registered under (Regular or Composition).

Missing GST return deadlines attracts late fees, interest at 18% per annum, and can eventually lead to cancellation of your GST registration. The Legal Team ensures every return is reconciled, accurate, and filed before the due date.

Frequently Asked Questions

Common questions about GST Return Filing.

Can I file GST returns quarterly?
Yes, businesses with annual turnover up to ₹5 crores can opt for the QRMP (Quarterly Return Monthly Payment) scheme — file GSTR-1 and GSTR-3B quarterly while paying estimated tax monthly.
What happens if I miss GSTR-1 filing?
Your buyers will not see your invoices in their GSTR-2B, preventing them from claiming Input Tax Credit. This often leads to vendor disputes plus late fees on your end.
Why is ITC reconciliation important?
ITC claimed in GSTR-3B must match GSTR-2B (auto-generated from your suppliers' filings). Excess ITC claims trigger GST notices and demand orders — we reconcile every month before filing.
What is GSTR-2B?
GSTR-2B is a static, monthly auto-drafted ITC statement based on your suppliers' GSTR-1 filings. It shows exactly how much Input Tax Credit you are eligible to claim for that period.
Is NIL return filing also mandatory?
Yes, even if there were no sales or purchases during the period, a NIL GSTR-1 and GSTR-3B must be filed to avoid late fees and registration cancellation risk.
Do I need to file returns even if I have no GST liability?
Yes. GST return filing is a compliance requirement regardless of whether tax is payable. Non-filing for 6 consecutive months can lead to cancellation of GSTIN by the department.
