What is GST Return Filing?
Every person registered under GST must report sales, purchases, tax collected and input tax credit (ITC) through GST returns on the GST portal. The returns you file depend on your type of registration and turnover.
Main GST Returns for Regular Taxpayers
GSTR-1: outward supplies
GSTR-1 reports invoice-wise details of B2B sales and summary details of B2C sales, credit notes, exports and HSN-wise summary. Your customers' ITC depends on what you report here, so accuracy and timeliness matter. It is generally due by the 11th of the following month for monthly filers.
GSTR-3B: summary return and tax payment
GSTR-3B is the summary return through which tax is actually paid after adjusting ITC. For monthly filers it is generally due by the 20th of the following month.
QRMP scheme
Taxpayers with aggregate turnover up to ₹5 crore can opt for the Quarterly Return Monthly Payment (QRMP) scheme, filing GSTR-1 and GSTR-3B quarterly while paying tax monthly. Quarterly GSTR-3B due dates are staggered by state, and Uttar Pradesh falls in the later group.
Annual return
GSTR-9 (annual return) and GSTR-9C (reconciliation statement) apply above specified turnover limits. Due dates and thresholds are notified each year.
Composition taxpayers
Composition dealers file a quarterly statement for payment (CMP-08) and an annual return (GSTR-4).
Our Typical GST Return Process
- Collect sales and purchase data from your books or Tally every month
- Prepare GSTR-1 and check B2B invoices, GSTINs and HSN codes
- Reconcile purchases with GSTR-2B and identify missing or ineligible ITC
- Compute tax liability, interest if any, and prepare GSTR-3B
- Share the working for approval, then file and share acknowledgements
- Track notices, mismatches and vendor follow-ups
Documents and Data Needed
- Sales invoices or sales register
- Purchase invoices and expense bills
- Credit and debit notes
- Bank statement (for cross-checking)
- E-way bills and e-invoices, where applicable
Common Mistakes to Avoid
- Claiming ITC that is not in GSTR-2B. This is one of the most common reasons for notices.
- Mismatch between GSTR-1 and GSTR-3B, which triggers automated scrutiny
- Claiming blocked credits, such as on certain motor vehicles, food and personal expenses
- Not reversing ITC when suppliers are not paid within 180 days
- Filing late, which causes late fees and interest, and can block e-way bill generation
- Ignoring nil returns. Nil returns are still mandatory.
Important Considerations
- GST rates were rationalised in September 2025, so check that your invoicing software applies the current rate for each HSN.
- Repeated non-filing can lead to cancellation of registration.
- Keep invoices and records for the period prescribed under GST law, as notices can come years later.
Frequently Asked Questions
Do I have to file GST returns if there are no sales?
Yes. Nil returns must be filed for every period while the registration is active.
Can a mistake in a filed GSTR-3B be corrected?
Errors are generally corrected in the next return within the time limits allowed. Some fields have restrictions, so take advice before filing.
