If your GST registration is active and you are required to file GSTR-1 and GSTR-3B, having no sales does not by itself remove the filing obligation. A NIL return is appropriate only when the portal’s NIL conditions are satisfied. For GSTR-3B, purchases, reverse-charge liability, interest/late fee or other reportable items can make a NIL filing incorrect even when outward sales are zero.
Zero revenue is a factual starting point, not the filing conclusion
A GSTR-3B NIL return requires more than no sales.
Regular taxpayers with an active GSTIN and no business activity for the period
Composition taxpayers follow different forms.
They assume no tax means no filing
GST filing obligation is tied to registration and return type, not just the existence of sales.
No outward supply, no inward supply/data that prevents NIL treatment, no manual entries and no outstanding interest/late-fee liability under portal rules
Also check reverse charge and prior-period obligations.
| Situation | NIL filing? | Check |
|---|---|---|
| No sales, no purchases, no liability | Potentially yes | Portal NIL conditions |
| No sales, purchase invoices exist | Do not assume | 2B/ITC and portal conditions |
| No sales, RCM expense | No simple NIL conclusion | RCM liability |
| No activity for many months | Returns still matter while active | Consider cancellation separately |
If truly NIL, file on time; if not, prepare the normal return
If inactivity is permanent or prolonged, separately assess whether cancellation is commercially appropriate.
No sales but one foreign vendor invoice
A dormant software company has zero customer invoices but pays a foreign SaaS vendor. That transaction can require GST analysis and means ‘no sales’ should not automatically become a NIL GSTR-3B.
Non-filing can create late fee and registration problems
The GSTIN remains active until lawfully cancelled.
We decide NIL from facts, not from turnover alone
Review covers outward supplies, purchases/2B, RCM, ledgers, outstanding charges and whether ongoing registration still makes sense.
What TargoLegal would ask for before filing or responding
The exact pack changes by issue, but these controls prevent the most common hand-off and accountability failures.
The proposed filing, payment, reversal, correction or response should be explained before submission. After filing, retain the ARN/filed PDF and any acknowledgement.
Do not make the problem harder to unwind
Reconcile books and source evidence before deciding tax treatment.
Use the exact period that created the mismatch, notice or filing obligation.
A correction should have a written bridge to the original error.
Save return PDFs, ARN, challans and the approved working.
What to send for a first review
No activity but GST still active? Send the GSTIN and last month with sales so the immediate question—NIL filing or cancellation review—can be separated.
Related questions
What should I send first?
Send the GSTIN, exact tax period and the document or mismatch that triggered the question. That usually determines the rest of the checklist.
Should I pay before reconciling?
Do not make a blind payment merely because a portal difference appears. Establish the legal and factual basis first, unless an undisputed liability is already clear.
Can the GST Portal data be wrong or incomplete?
Portal data is essential evidence but it still has to be reconciled with books, supplier/customer records and the applicable law.
What should I keep after filing?
Retain the filed return PDF, ARN, payment evidence, reconciliation working and any client-approved summary of adjustments.
When should I involve a GST professional?
Professional review is advisable where the issue affects material tax, ITC, notices, refund, registration status, exports, e-invoicing or multiple return periods.
