What is a NIL GST Return?
A NIL GST return is filed when your business has no sales, no purchases, and no tax liability during a particular tax period. Even if you had zero transactions, you are still required to file your GST returns to maintain compliance.
Think of it as telling the government "I had no business activity this period" - but you still need to formally report it.
Who Needs to File NIL Returns?
You must file NIL returns if you fall into any of these categories:
- Businesses registered under GST with no transactions in a month/quarter
- Seasonal businesses during off-season periods
- New businesses that haven't started operations yet
- Businesses temporarily closed but with active GST registration
- Dormant companies maintaining GST registration
If you skip filing NIL returns, late fees accumulate daily (₹20/day), your GST account can be suspended after prolonged non-filing, your compliance rating drops, and you cannot file future returns until pending ones are cleared.

- GST Portal credentials: Username and password for gst.gov.in

Late Fees for NIL Returns
Missing the deadline attracts late fees that accumulate daily.
Daily Late Fee Rates
The late fee consists of two equal parts under the CGST and SGST/UTGST Acts:
- NIL GSTR-1 & GSTR-3B: ₹20/day (₹10 CGST + ₹10 SGST)
- Regular GSTR-1 & GSTR-3B: ₹50/day (₹25 CGST + ₹25 SGST)
Maximum Late Fee Cap
| Scenario | Turnover / Type | Maximum Cap |
|---|---|---|
| NIL Return | Any Turnover | ₹500 (₹250 CGST + ₹250 SGST) |
| Regular Return | Up to ₹1.5 Crore | ₹2,000 |
| Regular Return | ₹1.5 Cr to ₹5 Cr | ₹5,000 |
| Regular Return | Above ₹5 Crore | ₹10,000 |
Even a few days' delay adds up. Set calendar reminders for the 11th and 20th of each month to file on time and avoid unnecessary costs.
Common Mistakes to Avoid
Missing the deadline: Even NIL returns have due dates. Mark your calendar for the 11th (GSTR-1) and 20th (GSTR-3B) of each month.
Not filing previous periods first: You cannot file the current month's NIL return if previous months are pending. The GST portal will block you.
Trying to file NIL with saved records: If you've saved any data in GSTR-1 (even accidentally), you must delete it before selecting the NIL filing option.
Wrong tax period selection: Double-check the month/quarter you're filing for. Filing for the wrong period creates compliance issues.
Frequently Asked Questions
QCan I file NIL return if I have ITC balance?
Yes, you can file NIL GSTR-3B even if you have ITC (Input Tax Credit) balance from previous periods. The ITC will remain in your credit ledger and can be used in future periods when you have tax liability.
QWhat if I miss the NIL return deadline?
You'll need to pay the late fee (₹20/day for NIL returns) up to the maximum cap of ₹500 per return. File as soon as possible to minimize penalties.
QIs NIL return filing mandatory every month?
Yes, if you're a regular taxpayer registered under GST. Composition dealers file quarterly. Not filing leads to penalties, affects your compliance rating, and can eventually lead to GST registration cancellation.
QCan I file NIL return via SMS?
Yes, you can file both NIL GSTR-3B and NIL GSTR-1 via SMS from your registered mobile number. For GSTR-3B, send: NIL 3B <space> 15-digit GSTIN <space> Return Period (MMYYYY) to 14409. Example: NIL 3B 27AABCU9603R1ZM 012026 for January 2026. For GSTR-1, send: NIL R1 <space> 15-digit GSTIN <space> Return Period (MMYYYY) to 14409. After sending, you will receive a 6-digit validation code (valid for 30 minutes). Confirm by sending: CNF 3B <space> code (or CNF R1 <space> code for GSTR-1). You will receive an ARN upon successful filing.
QWhat happens if I have auto-populated records in GSTR-1?
You must delete or reset the saved/auto-populated records before filing NIL return. The portal will show an error if you try to file NIL with existing records. Use the RESET button or manually delete records from each tile.
QCan my GST registration be cancelled for not filing NIL returns?
Yes. Continuous non-filing of returns (typically 6 months for regular taxpayers) can lead to suo-moto cancellation of your GST registration by the tax authorities.
