GST Amnesty Scheme 2026: Notification & Filing Steps

Why the 2026 GST Amnesty Notification Demands Immediate Action

Your clients' GST portals are sitting on years of pending returns — and the government has just reopened the window to clear them at near-zero cost. The GST amnesty scheme 2026 notification offers a complete or substantially reduced late fee waiver on several overdue return categories, but the benefit is strictly time-bound. Miss the filing deadline and the full late fee liability under Sec 47 of the CGST Act revives automatically. This post walks you through exactly who qualifies, which forms are involved, and the precise sequence to file on the GST portal before time runs out.

What the Notification Actually Says

The CBIC has issued notifications under Sec 128 of the CGST Act, which empowers the government to waive or reduce late fees. The 2026 amnesty builds on the pattern of earlier schemes (Notification No. 07/2023-CT and its successors) and extends relief to taxpayers who failed to file returns for specified tax periods.

Key relief categories under the 2026 scheme (as notified by CBIC):

• GSTR-3B (monthly/quarterly): Late fee reduced to ₹500 per return (₹250 CGST + ₹250 SGST) for nil-tax-liability periods; capped at ₹1,000 per return (₹500 CGST + ₹500 SGST) for returns with tax liability, for the specified past periods.
• GSTR-9 (annual return): Late fee waived or capped for financial years covered under the notification window.
• GSTR-10 (final return): Late fee capped at ₹500 (₹250 CGST + ₹250 SGST) for registered persons whose registration has been cancelled or surrendered.

Always verify the current notification number and exact cap figures at cbic-gst.gov.in before advising clients — the CBIC updates these periodically and the operative circular supersedes any summary.

GST Amnesty Scheme 2026 Eligibility: Who Qualifies

Not every delinquent filer is covered. Run through this checklist before you touch the portal.

Criterion	GSTR-3B Relief	GSTR-9 Relief	GSTR-10 Relief
Return was due for a period specified in the notification	✅	✅	✅
Return not yet filed as on the amnesty notification date	✅	✅	✅
Registration active or cancelled after the due period	✅	✅	✅ only if cancelled
Pending tax (interest under Sec 50 CGST Act) also paid	✅ Required	✅ Required	N/A (nil tax)
Filing completed within the amnesty window dates	✅ Mandatory	✅ Mandatory	✅ Mandatory

Critical exclusion: The waiver applies only to late fees under Sec 47. Interest under Sec 50 on unpaid tax is not waived — you must discharge the full interest liability simultaneously, otherwise the return will remain in a deficient state and the reduced late fee benefit may not apply.

Practical example: A proprietor with GSTR-3B pending for six months, each with ₹80,000 tax liability. Normal late fee would be ₹300/day (₹150 CGST + ₹150 SGST) per return. Under the amnesty cap, total late fee across six returns is ₹6,000 (6 × ₹1,000) instead of potentially ₹54,000+. The interest on ₹80,000 per month at 18% p.a. (Sec 50(1)) still applies and must be paid in full.

GST Amnesty Scheme 2026 Filing Steps: The Exact Portal Sequence

This is the workflow that trips up most practitioners — do it out of sequence and the system will not auto-apply the reduced fee.

Step 1 — Gather outstanding return data Log in to the GST portal (gst.gov.in). Navigate to Returns Dashboard and note every period showing "Not Filed." Cross-check with the notification's specified period list.

Step 2 — Compute interest liability first Before opening the return, compute Sec 50 interest on unpaid tax for each period. Use the formula: Tax payable × 18% ÷ 365 × number of days delayed. Record this figure — you will need it for the DRC-03 or within the return itself.

Step 3 — File GSTR-1 (if not already filed) The GST portal will not allow GSTR-3B filing for a period if the corresponding GSTR-1 is pending. File or amend GSTR-1 first. For QRMP filers, ensure the IFF (Invoice Furnishing Facility) entries for the relevant quarters are complete.

Step 4 — Open GSTR-3B for the earliest pending period Always file in chronological order (oldest first). The portal calculates late fees automatically based on the filing date. Under the amnesty window, it will apply the reduced cap if the notification period conditions are met. Do not manually override the system-computed late fee — this can trigger a mismatch.

Step 5 — Pay tax, interest, and the capped late fee On the payment page, the challan (PMT-06 for QRMP / standard challan otherwise) will show three components: tax, interest, and late fee. Ensure all three are paid in the same session. Partial payment of tax will leave the return unfiled and forfeit the amnesty benefit.

Step 6 — Repeat for each pending period in sequence File each month/quarter one by one. Do not batch them — the portal processes them individually.

Step 7 — GSTR-10 filers: separate workflow If a client's registration was cancelled and GSTR-10 was not filed, navigate to Returns > Final Return > GSTR-10. The reduced late fee of ₹500 will reflect automatically during the amnesty window. Attach the cancellation order reference.

Step 8 — Download the acknowledgement After each successful filing, download the ARN (Acknowledgement Reference Number) confirmation. Maintain these for at least six years per recordkeeping norms under Rule 56 of the CGST Rules.

Common Errors That Void the Amnesty Benefit

Practitioners lose the benefit in predictable ways. Watch for these:

• Filing GSTR-3B without filing GSTR-1 first — the portal blocks submission or creates a mismatch flag.
• Paying late fee before the return is actually submitted — challan payment alone does not constitute filing.
• Missing the amnesty window end date — the system reverts to full late fee on the day after the deadline. Set a calendar reminder two weeks before close.
• Ignoring Sec 50 interest — submitting the return with zero interest results in a short-payment notice under Sec 73/74 CGST Act later.
• Filing GSTR-9 without reconciling GSTR-1 and GSTR-3B data — the annual return auto-populates from filed monthly data; discrepancies will require an amendment.

Interest Calculation Worked Example

Situation: GSTR-3B for July 2024 was due on 20 August 2024. Filed on 15 March 2026 under the amnesty. Tax payable: ₹1,20,000.

• Days delayed: 20 August 2024 to 15 March 2026 = approximately 573 days
• Interest = ₹1,20,000 × 18% ÷ 365 × 573 = ₹33,979
• Late fee under amnesty: ₹1,000 (capped, since tax liability exists)
• Total additional outgo: ₹34,979

Without the amnesty, late fee alone at ₹300/day × 573 days = ₹1,71,900. The scheme saves over ₹1.70 lakh in late fees on this single return.

After Filing: Reconciliation and Documentation Checklist

Filing is not the end of the engagement. Complete these steps immediately after:

• Reconcile ITC in GSTR-2B — late-filed returns from suppliers may now surface in your client's GSTR-2B. Re-check ITC eligibility under Sec 16(2)(c) CGST Act for the rectified periods.
• Update the books — post the interest expense and late fee payment in Tally Prime or Zoho Books against the correct financial year. Interest on late payment of tax is not deductible under Sec 37 of the Income Tax Act 1961.
• Retain the CBIC notification — attach the relevant notification PDF to the client file as the legal basis for the reduced fee. The official source is cbic-gst.gov.in.
• Advise on future compliance — the root cause is usually a cash-flow crunch delaying payment. Consider switching eligible clients to the QRMP scheme (quarterly filing, monthly payment) to reduce compliance frequency.
