Every GST-registered business must file returns on a fixed schedule — regardless of whether there was any sale in that period. Our GST filing plans start from ₹299 per return, with every filing reconciled against your purchase and sales data before submission.
Overview of GST Returns
GSTR-1
Monthly/quarterly statement of outward supplies (sales) — feeds your buyers' input tax credit.
GSTR-3B
Monthly summary return declaring sales, purchases, tax liability, and net GST payment.
GSTR-9
Annual return consolidating all monthly/quarterly filings for the financial year.
GSTR-9C
Reconciliation statement required alongside GSTR-9 above a notified turnover threshold.
Due Dates
• GSTR-1: 11th of the following month (monthly filers)
• GSTR-3B: 20th of the following month (monthly filers)
• QRMP filers: GSTR-1 by the 13th, GSTR-3B by the 22nd/24th after the quarter, with monthly tax payment via challan
• GSTR-9: annual, by the government-notified due date each year (commonly December 31 following the financial year)

The QRMP Scheme
Businesses with turnover up to ₹5 crore can opt for QRMP (Quarterly Return, Monthly Payment) — filing GSTR-1 and GSTR-3B quarterly while still paying tax monthly via a simple challan. It reduces filing frequency without delaying tax payment to the government.
NIL Returns
Even with zero business activity in a period, a NIL GSTR-1 and GSTR-3B must still be filed. Skipping this attracts late fees and can put your registration at risk of cancellation if pending for a prolonged period.
E-Way Bills
An e-way bill is required for movement of goods valued above ₹50,000 by road, rail, air, or vessel. It must be generated before the goods start moving. We help set up and validate e-way bills as part of our filing plans.
Late Fees & Interest
Late filing attracts ₹50/day (₹25 CGST + ₹25 SGST) for regular returns, or ₹20/day for NIL returns, subject to a turnover-based cap — plus 18% per annum interest on any tax paid late. Try our late fee calculator and interest calculator to estimate what you owe.
Common Filing Mistakes
• Mismatched sales figures between GSTR-1 and GSTR-3B
• Claiming ineligible input tax credit
• Missing reverse-charge liability
• Forgetting to file NIL returns
• Late tax payment leading to avoidable interest

Frequently Asked Questions
GSTR-1 is a monthly/quarterly statement of all outward supplies (sales) — it feeds your buyers' input tax credit. GSTR-3B is a monthly summary return where you declare total sales, purchases, tax liability, and pay the net GST due. Both must be filed even if there's no business activity in a period (as a NIL return).
For monthly filers: GSTR-1 is due on the 11th of the following month, and GSTR-3B is due on the 20th. Quarterly filers under the QRMP scheme file GSTR-1 by the 13th of the month after the quarter and GSTR-3B by the 22nd or 24th (depending on state), with monthly tax payment via a challan in between. Our GST due-date checker tool keeps these dates handy.
QRMP (Quarterly Return, Monthly Payment) lets taxpayers with turnover up to ₹5 crore file GSTR-1 and GSTR-3B quarterly while still paying tax monthly through a simple challan. It reduces filing frequency without delaying tax payment to the government.
Yes. Even with zero business activity, a NIL GSTR-1 and GSTR-3B must be filed for every applicable period. Skipping this still attracts late fees, and can lead to your registration being flagged for cancellation if returns are pending for a prolonged period.
GSTR-9 is the annual return that consolidates all monthly/quarterly returns filed during the financial year. It is mandatory for regular taxpayers above a government-notified turnover threshold and optional (but advisable) below it. Our Compliance Pro plan includes GSTR-9 filing.
An e-way bill is required for the movement of goods valued above ₹50,000 (single invoice or consolidated) when transported by road, rail, air, or vessel — whether it's a sale, transfer, or return of goods. It must be generated before the goods start moving and carried along with the consignment.
GST returns can't be revised once filed. Instead, corrections for errors or omissions are made in the return of a subsequent period (for example, correcting a GSTR-1 entry from March in the following month's GSTR-1), subject to the annual amendment cut-off date.
The standard late fee is ₹50 per day of delay (₹25 CGST + ₹25 SGST) for regular returns, and ₹20 per day (₹10 + ₹10) for NIL returns, subject to a government-notified maximum cap that depends on turnover. Interest at 18% per annum also applies on any tax paid late. Our GST late fee and interest calculators estimate this instantly.
Common errors include mismatched sales figures between GSTR-1 and GSTR-3B, claiming ineligible input tax credit, missing reverse-charge liability, forgetting to file NIL returns, and late payment of tax leading to avoidable interest. We reconcile these figures before every filing to catch mismatches early.
