GST Return Filing Status — Check GSTR-3B & GSTR-1 by GSTIN
This tool shows the GST return filing status of any registered taxpayer — month by month, for both GSTR-3B and GSTR-1. Enter a GSTIN, select a financial year, and see a clear table of which returns have been filed and for which tax periods. No login, no fees, live data directly from GSTN.
How to Do a GST Return Status Check
The tool works in three steps and delivers results in seconds:
1
Enter the GSTIN — To check GST return filing status by GSTIN no., enter the full 15-digit GST Identification Number exactly as it appears on the invoice or registration certificate. Even one wrong character will return no results.
2
Select the Financial Year — GST financial years run from April to March. Choose the year that covers the months you want to verify. For example, invoices from July 2025 fall under FY 2025-26.
3
Click Check Status — The tool fetches live data from the GSTN database and displays two separate filing tables — one for GSTR-3B and one for GSTR-1 / IFF / GSTR-1A — covering every tax period in that year.

↑ Sample output — actual results show data for the GSTIN and financial year you enter
The GSTR-3B table shows three columns: Financial Year, Tax Period (the month), and Status. The GSTR-1 table has an additional Return Type column which shows whether the return filed was GSTR-1, IFF (Invoice Furnishing Facility for quarterly filers), or GSTR-1A (amendment return). Both tables cover the complete financial year from April to March.
Note on filing frequency: Taxpayers who opted for the QRMP scheme file GSTR-1 quarterly (via IFF for the first two months). In this case, some months in the GSTR-1 table may show IFF instead of GSTR-1, or may not appear at all for months when no IFF was filed.
Why This Check Matters for Your Business
Under goods and services tax filing rules, your Input Tax Credit (ITC) depends directly on what your suppliers file — not just on the invoices they give you. These are the most common situations where checking the status makes a real difference:
🛡️
Protect Your ITC
ITC is valid only when your supplier has filed their returns and the invoice appears in your GSTR-2B. A quick check before settling payment prevents ITC loss later.
📅
Track Your Own GST Returns
Check your own GST returns history to confirm every month is accounted for. A missed period means accumulating late fees — this tool makes the gap immediately visible.
🤝
Vendor Verification
Before finalising a new supplier, their month-by-month filing record tells you how consistent they are. Frequent gaps in the table are a sign worth noting before entering a long-term agreement.
📊
Monthly Reconciliation
Running this check on your key vendors each month lets you reconcile GSTR-2B against your purchase register before you file your own return — no last-minute surprises.
ITC Risk: Under Section 16 of the CGST Act, ITC is blocked when a supplier has not filed their GSTR-3B or when the invoice is not reflected in GSTR-2B. The department can issue a demand notice with interest if you claim ITC on such invoices.
GSTR-1 and GSTR-3B — Why the Tool Shows Both
The tool shows GSTR-1 and GSTR-3B as two separate tables because they serve different purposes, and a supplier must file both to be considered fully compliant. Here is what each one does:
GSTR-3B — Monthly Tax Payment
Filed every month, GSTR-3B is where a taxpayer reports a summary of their sales and purchases and pays the net GST liability. The table shows the Tax Period (month) and whether this return was filed for each month of the year. A "Not Filed" entry here means the supplier has not paid their tax for that month.
GSTR-1 / IFF / GSTR-1A — Sales Return
This return reports all outward supplies (sales) in detail. The table includes a Return Type column — GSTR-1 for monthly filers, IFF for quarterly filers, and GSTR-1A for amendments. When a supplier files this return and uploads your invoice, it becomes visible in your GSTR-2B — which is the basis for your ITC claim.
A supplier can file GSTR-1 (making your invoice visible in GSTR-2B) while skipping GSTR-3B (not actually paying the tax collected). This is a compliance red flag that this tool makes immediately visible — which is why checking both columns matters for a thorough compliance review.
Understanding the GST Filing Status in the Results
The Status column in both tables will show one of these values. Here is what each one means and what action it suggests:
| Status Shown |
What It Means |
What You Should Do |
| Filed |
Return submitted successfully for this tax period. |
ITC on invoices from this supplier for this month is safe to claim. |
| Not Filed |
Return has not been submitted for this tax period. |
Hold ITC on their invoices for this month. Follow up with the supplier to file. |
| Filed — Late |
Return was filed after the due date for this period. |
ITC is still claimable. The late filing is a compliance signal — monitor future periods. |
| To Be Filed |
Due date has not passed — return is pending but not overdue yet. |
Recheck after the due date before finalising your own ITC claim for this period. |
| Not Applicable |
This return is not required for this taxpayer or period. |
No action needed. Common for quarterly filers or newly registered taxpayers. |
Tips for Getting the Most from This Tool
- Match the GSTIN to the invoice — Always verify the GSTIN you enter matches the one printed on the supplier's invoice. A single character difference will pull data for a different taxpayer entirely.
- Check both tables independently — Do not assume that a Filed status in the GSTR-3B table means the GSTR-1 table is also Filed. The tool shows both because both matter — always review each column separately.
- Identify the filing type — The Return Type column in the GSTR-1 table tells you whether the taxpayer files monthly (GSTR-1) or quarterly (IFF). This affects which months will have entries and which will show Not Applicable.
- Use the right financial year — An invoice from January 2026 belongs to FY 2025-26, not FY 2026-27. Selecting the wrong year will show empty or incorrect results for the months you want to check.
- Recheck before filing your own return — A supplier's GST filing status can change. A vendor who showed Not Filed mid-month may have filed by your return due date — always recheck before finalising reconciliation.
- Cross-verify with GSTIN lookup — Before checking the filing history, confirm the GSTIN is active and genuine using our GST Verification tool. A cancelled GSTIN cannot have recent filed returns.
Frequently Asked Questions
What exactly does this tool show?
+
The tool shows two filing tables for any GSTIN. The first table — Filing details for GSTR-3B — shows Financial Year, Tax Period, and Status for each month. The second — Filing details for GSTR-1 / IFF / GSTR-1A — shows Financial Year, Return Type, Tax Period, and Status. Together these two tables give you the complete GST return status picture for that taxpayer for the selected year.
Why does the GSTR-1 table show IFF instead of GSTR-1 for some months?
+
IFF (Invoice Furnishing Facility) is used by taxpayers on the quarterly QRMP scheme. Instead of filing a full GSTR-1 every month, they file IFF for the first two months of each quarter to upload invoices for their buyers. The third month of the quarter gets a full GSTR-1 filing. So you may see IFF → IFF → GSTR-1 repeating across the year. This is normal and not a compliance gap.
What is the difference between GSTR-3B and GSTR-1 in this context?
+
GSTR-3B is the monthly tax payment return — it shows whether a supplier has actually paid the GST they collected. GSTR-1 is the sales detail return — it shows whether the supplier has uploaded their invoice data, which is what makes your GSTR-2B populate for ITC claims. Both are essential parts of the goods and service tax return cycle. Filing one without the other is a partial compliance gap.
Is it mandatory to file GST returns even when there is no turnover?
+
Yes. Every GST-registered taxpayer must file returns for every period — even a Nil Return when there is zero business activity. Skipping a return leads to daily late fees that accumulate until the return is filed. The tool will show a Not Filed status for that period, which is a clear signal to act.
My supplier's GSTR-3B shows Not Filed. What should I do?
+
Hold the GST amount from their payment until the status changes to Filed. Paying a supplier whose returns are pending puts your ITC at risk — the department can reject your ITC claim with interest if the supplier has not deposited the tax. Inform your supplier and ask them to file immediately. If you need help managing this, see our
GST Return Filing service.
Can I do GST return filing online through this tool?
+
No — this tool is for checking filing status only, not for submitting returns. For
GST return filing online, you need to log in to the official GST portal at
gst.gov.in, or use LegalDev's
GST Return Filing service where our team manages the entire filing process for you.
How accurate and current is the data shown?
+
