GSTR-3B Late Fee Waiver: GST Amnesty Scheme 2026 Filing Steps

Your client's GSTR-3B for FY 2022-23 has been sitting pending for months, and the accumulated late fee under Section 47 of the CGST Act looks terrifying on paper. The GST Amnesty Scheme 2026, announced via CBIC notification, changes that arithmetic dramatically — but only if you file within the window and navigate the portal correctly. Here is exactly what to do.

What the GST Amnesty Scheme 2026 Actually Caps

The scheme operates through an amendment to Section 47 of the CGST Act, giving effect to the late fee cap announced in the Union Budget 2024-25 and formalised through subsequent CBIC notifications (refer to the official CBIC portal at cbic-gst.gov.in for the current notification number applicable to your jurisdiction).

The practical caps are:

Return Type	NIL Tax Liability Returns	Returns with Tax Liability
GSTR-3B	₹500 per return (₹250 CGST + ₹250 SGST)	₹1,000 per return (₹500 CGST + ₹500 SGST)
GSTR-4 (Composition)	₹500 per return	₹500 per return
GSTR-9 (Annual)	₹20,000 per return (existing cap)	₹20,000 per return
GSTR-10 (Final Return)	₹1,000 (flat)	₹1,000 (flat)

The amnesty window covers returns for tax periods from July 2017 to a cutoff quarter announced in the notification — verify the precise end date on the CBIC portal before advising clients, as it has been extended in previous iterations. The scheme is available only for returns filed during the amnesty window; if you wait until after the window closes, the full Section 47 late fee applies with no cap.

This changes your workflow immediately. Any pending GSTR-3B you have been deferring because the late fee looked prohibitive should now be escalated and filed before the deadline.

Who Is Eligible — and Who Is Not

Eligibility is straightforward but has one critical exclusion that catches practitioners off guard.

Eligible:

• Registered taxpayers (regular scheme, composition dealers, casual taxable persons) who have not filed GSTR-3B, GSTR-4, GSTR-9, or GSTR-10 for the covered periods.
• Taxpayers whose registration has since been cancelled — they remain eligible for GSTR-10 filing under the capped fee.
• Taxpayers who filed the returns after the original due date but before the amnesty notification — the excess late fee already paid is not refundable. Only future filings within the window benefit.

Not eligible:

• Taxpayers who have already received a final adjudication order under Section 73 or 74 of the CGST Act for the same period.
• Returns outside the notified coverage period.

The single most important exclusion to explain to clients: Section 50(1) interest on delayed tax payment is not waived under this scheme. If your client's GSTR-3B for Q2 FY 2022-23 shows tax payable, interest at 18% per annum (or 9% for net tax liability cases under proviso to Section 50(1)) accrues from the original due date to the actual date of payment. This is a separate obligation from the late fee and must be computed and discharged in full before the return will be accepted by the portal.

Run the interest calculation before you open the portal. A client with ₹5 lakh outstanding for 18 months faces approximately ₹1.35 lakh in interest alone — the ₹500 late fee cap is welcome, but the interest bill is where the real discussion needs to happen.

Exact GST Portal Navigation: Step-by-Step

This is the walkthrough most guides skip. Follow these steps precisely on the GST portal (www.gst.gov.in):

Step 1 — Login Log in to the taxpayer's GSTIN account. Ensure the Digital Signature Certificate (DSC) or EVC is ready before starting.

Step 2 — Go to Services > Returns From the top navigation bar, select Services, then Returns, then Returns Dashboard. Do not use the "File Returns" quick link on the home page — it may route you to the wrong filing year.

Step 3 — Select the Financial Year and Return Period On the Returns Dashboard, use the Financial Year and Return Filing Period dropdown menus. Select the period for which the pending GSTR-3B exists (e.g., FY 2022-23, September 2022). Click Search.

Step 4 — Identify the Pending Return Tile The dashboard displays all returns for the selected period. The GSTR-3B tile will show status as "Not Filed" with a Prepare Online or Prepare Offline button. Before clicking, note the Late Fee amount displayed — under the amnesty, this should reflect the capped figure (₹500 or ₹1,000) once the system has updated. If it still shows the pre-cap amount, do not file immediately; raise a query on the CBIC GST helpdesk (1800-103-4786) or wait for the portal to sync the notification.

Step 5 — Prepare the Return (Table-by-Table) Click Prepare Online. Navigate through the tables:

• Table 3.1 — Outward taxable supplies (verify auto-populated figures from GSTR-1 if already filed).
• Table 4 — Eligible ITC (confirm Sec 16(2)(c) reconciliation is complete; ITC claims in a late return remain subject to the annual cap under Sec 16(4)).
• Table 5 — Exempt, nil-rated, and non-GST inward supplies.
• Table 5.1 — Interest and Late Fee. This is the critical table. The portal auto-computes the late fee here. Under the amnesty, the fee should display the capped amount. Compute your Section 50(1) interest manually and enter it in the interest field — the portal does not auto-calculate interest with full accuracy for older periods.

Step 6 — Pay Tax, Interest, and Late Fee via PMT-06 / Electronic Cash Ledger Navigate to Services > Payments > Create Challan. Pay in this order:

1. Tax liability (IGST / CGST / SGST as applicable) — ensure the Electronic Cash Ledger and Electronic Credit Ledger balances are sufficient.
2. Interest (18% or 9% per Section 50(1)).
3. Late fee (capped amount under the amnesty).

Do not offset late fees against the Input Tax Credit — late fees are payable only through the cash ledger per Rule 87 of the CGST Rules.

Step 7 — Submit and File Return to the Returns Dashboard, select the period, click Submit (this freezes the data), verify the Table 5.1 figures, then click File with DSC or File with EVC. Download the ARN confirmation immediately and archive it.

Step 8 — Track Status Go to Services > Returns > Track Return Status. Enter the ARN. Status should move from "Submitted" to "Filed" within minutes during off-peak hours. If it stays at "Submitted" for more than 24 hours, the portal may have a processing backlog — do not re-file; contact the helpdesk with the ARN.

ITC Implications of Filing a Late GSTR-3B

Filing a late GSTR-3B does not automatically restore Input Tax Credit that was time-barred. Section 16(4) of the CGST Act restricts ITC claims to the earlier of: (a) the due date of September return for the next financial year, or (b) the date of filing the annual return. Late filing under amnesty does not override this restriction — if the November 2023 deadline for FY 2022-23 ITC has passed, those credits cannot be claimed even if the return is now filed under the amnesty window.

This is a nuanced point worth flagging explicitly to clients who assume that filing the late return "unlocks" old ITC. It does not. The amnesty benefits are limited to the late fee cap — nothing more.

If you want to sharpen your instincts on ITC reconciliation edge cases before they surface in client work, the SuperAccountant skills quiz has a dedicated GST module that surfaces exactly these scenario-based gaps.

Common Errors That Reject the Filing

Even with the amnesty in place, several common errors cause portal rejections or result in the capped fee not applying:

• GSTR-1 not filed for the same period. The portal blocks GSTR-3B filing if GSTR-1 is outstanding for that tax period. File GSTR-1 first.
• Cash ledger insufficient for late fee. Even ₹500 must be in the cash ledger; ITC cannot be used. Ensure the client tops up via NEFT/RTGS challan before you begin the filing session.
• Interest field left blank. The return will be filed but a demand notice under Section 73 will follow. Always enter interest in Table 5.1, even if the computation is approximate.
• DSC expired. A common delay for director-level signatories. Verify DSC validity at least 48 hours before the session.
• Wrong GSTIN selected. Multi-entity clients with multiple GSTINs under one login — always double-check the active GSTIN in the top-right corner of the portal before filing.

What Happens If You Miss the Amnesty Window

The consequences are straightforward and expensive. Late fees revert to the full Section 47 rate: ₹50 per day (₹25 CGST + ₹25 SGST) for returns with tax liability, and ₹20 per day for NIL returns, subject to a ceiling of 0.25% of turnover in the state. For a taxpayer with ₹1 crore monthly turnover and an 18-month delay, the uncapped late fee calculation alone can run into several lakh rupees.

Beyond the financial cost, continued non-filing triggers the suspension workflow under Rule 21A of the CGST Rules, and ultimately registration cancellation under Section 29(2)(c). The amnesty window is genuinely the lowest-cost resolution path for any pending return within the covered periods.

Practical Checklist Before You File

Before opening the portal session, confirm all of the following:

• GSTR-1 filed for the same tax period
• Section 50(1) interest computed and noted (18% or 9% per proviso)
• Electronic Cash Ledger topped up for tax + interest + late fee
• ITC eligibility under Sec 16(2)(c) verified (supplier's GSTR-1/2B match)
• Sec 16(4) deadline checked — ITC not claimed if time-barred
• DSC validity confirmed for authorised signatory
• Correct GSTIN selected in portal
• ARN download template ready for client communication
• Checked CBIC portal for current amnesty window end date

Bookmark the CBIC GST portal (cbic-gst.gov.in) for the live notification — the window dates and covered return periods are periodically extended, and you want to be working from the current version, not a secondary summary.

For practitioners managing multiple pending returns across a client portfolio, consider batch-scheduling filings by period — oldest periods first — to manage cash ledger replenishment and avoid last-minute portal congestion as the deadline approaches. The GST portal historically experiences high traffic in the final 48–72 hours before any amnesty deadline.
