GSTR-3B Late Fee Waiver 2026: Filing Steps for Freshers
The GST amnesty scheme 2026 notification gives defaulters a rare clean slate — here is the exact GSTR-3B filing walkthrough, common error fixes, and deadline maths every first-job accountant needs right now.
By the SuperAccountant Editorial Team
Your senior just dropped a file on your desk: twenty GST-registered clients with unfiled GSTR-3B returns going back two or three years, and the instruction is "sort this out before the amnesty window closes." If you have never filed a GSTR-3B in your life, that sentence is terrifying. This post walks you through the entire workflow — the amnesty notification context, the step-by-step portal process, the numbers, and the errors that trip up first-timers — so you can walk back to your senior with clean filed acknowledgements, not excuses.
What the GST Amnesty Scheme 2026 Notification Actually Says
The Central Board of Indirect Taxes and Customs (CBIC) has periodically issued late-fee waiver notifications under Section 128 of the CGST Act, 2017, which empowers the government to waive or reduce late fees. The 2026 amnesty builds on this same legal foundation.
Under the scheme, late fees under Section 47 of the CGST Act — which accrue at ₹50 per day (₹25 CGST + ₹25 SGST) for regular returns or ₹20 per day for nil-liability returns — are either waived entirely or capped at a significantly reduced amount for GSTR-3B returns that were due for specified tax periods but remained unfiled. Always verify the exact cap and eligible tax periods directly on the official CBIC portal at cbic-gst.gov.in since notification numbers and period ranges update with each amnesty window.
What this means in practice: A client who has not filed GSTR-3B for 18 months could face a late fee of ₹50 × 540 days = ₹27,000 in normal circumstances. Under the amnesty cap, that same client might owe only ₹500–₹1,000 — a reduction that makes filing financially viable. Your job is to get those returns filed before the amnesty deadline expires.
The GSTR-3B Late Fee Waiver: Who Qualifies and What to Check First
Before you touch the GST portal, run this eligibility check for each client or employer:
| Check | What to verify | Where to look |
|---|---|---|
| Registration status | GSTIN is active, not suspended or cancelled | GST portal → Search Taxpayer |
| Tax period | Return falls within the amnesty-notified period | CBIC notification / cbic-gst.gov.in |
| Return type | GSTR-3B (monthly or quarterly QRMP filer) | Registration certificate |
| Liability | Whether nil or with tax payable | Books of accounts / Tally Prime |
| Prior payments | Any tax already paid via DRC-03 | GST portal → Electronic Liability Register |
A common fresher mistake is jumping straight to the portal without confirming the tax period. If the unfiled return sits outside the amnesty window, the reduced fee does not apply and you owe the full late fee — an embarrassing conversation to have with a client after the fact.
Step-by-Step GSTR-3B Filing on the GST Portal (2026 Walkthrough)
This walkthrough assumes you are filing on behalf of a regular monthly taxpayer. The QRMP process is nearly identical but uses the IFF (Invoice Furnishing Facility) for B2B invoices in months 1 and 2.
Step 1 — Log in and navigate Go to GST Portal → Services → Returns → Returns Dashboard. Select the financial year and the return period (e.g., April 2024). Click "GSTR-3B."
Step 2 — Populate Table 3.1 (Outward Supplies) Enter taxable value and IGST/CGST/SGST under the correct heads:
- 3.1(a): Outward taxable supplies (other than zero-rated, nil rated, and exempted)
- 3.1(b): Outward taxable supplies — zero rated
- 3.1(c): Other outward supplies — nil rated, exempted
Cross-check these figures with GSTR-1 already filed (or with the books if GSTR-1 is also pending). A mismatch between GSTR-1 and GSTR-3B triggers a system flag in GSTR-9 annual reconciliation — something you do not want to inherit.
Step 3 — Populate Table 3.2 (Inter-State Supplies) Report supplies to unregistered persons, composition dealers, and UIN holders broken down by state. Many freshers skip this table entirely. Do not — it is mandatory.
Step 4 — Table 4: ITC (Input Tax Credit) This is where most errors originate. Under Section 16(2)(c) of the CGST Act, ITC can be availed only if the supplier has filed their return. Pull the auto-populated ITC from GSTR-2B (not GSTR-2A — GSTR-2B is the static monthly statement used for ITC claims as per Rule 36(4) of the CGST Rules). Reverse any ITC that does not appear in GSTR-2B.
Step 5 — Compute tax payable and set-off The portal computes this automatically once you save Tables 3 and 4. Verify the liability register. Pay any outstanding tax using the Electronic Cash Ledger (top up via Challan PMT-06 if the balance is insufficient) before proceeding.
Step 6 — Preview, verify, and file Click "Preview Draft GSTR-3B" and download the PDF. Review it against your working file. When satisfied, file using:
- DSC (Digital Signature Certificate) — mandatory for companies
- EVC (Electronic Verification Code via OTP) — available for proprietorships and partnerships
Once filed, download the ARN (Acknowledgement Reference Number) confirmation. Save this — it is your proof of compliance.
Step 7 — Check the late fee auto-population After filing, the portal auto-calculates the late fee based on days of delay. Under the amnesty notification, the fee should reflect the capped amount. If it shows the full uncapped fee, raise a ticket on the GST portal helpdesk immediately — do not make payment until the amount is confirmed. Verify the reduced figure against the CBIC notification on cbic-gst.gov.in.
Common Errors That Trip Up First-Job Accountants (and How to Fix Them)
Error: "GSTR-3B for the period is already submitted but not filed" Someone clicked "Submit" in an earlier session but did not complete filing. The return is locked. You cannot edit it. File it as-is after paying any outstanding liability. If the figures are wrong, you will need to correct them in subsequent returns — GSTR-3B has no revision facility.
Error: ITC mismatch / excess ITC claimed Cross-check Table 4(A) against GSTR-2B. Remove any ITC not reflected there. If you have already over-claimed in a prior return, reverse it in the current period under Table 4(B)(2) to avoid a demand notice under Section 73 or 74 of the CGST Act.
Error: Late fee not reflecting the waived amount This occasionally happens when the portal cache has not updated to the latest notification. Log out, clear browser cache, log back in. If the issue persists, call the GST helpdesk (1800-103-4786) or raise a grievance on the portal.
Error: "Invalid GSTIN" during filing The GSTIN may have been suspended due to non-filing. Check status at GST Portal → Search Taxpayer. A suspended GSTIN needs to be restored before filing — this requires a separate application.
Salary Reality: What GST Filing Skills Are Worth in Your First Job
Knowing GSTR-3B filing end-to-end — including amnesty handling — puts you ahead of most fresh B.Com graduates who have only theoretical knowledge. Here is a realistic salary band for roles where this skill is immediately tested:
- Accounts Executive (GST focus), Tier-2 city CA firm: ₹15,000–₹22,000 per month
- Accounts Assistant, mid-size trading company: ₹18,000–₹28,000 per month
- Tax Associate, Big-4 or mid-tier firm (KPMG, Grant Thornton, BDO India): ₹25,000–₹35,000 per month (CTC, including variable)
- GST Compliance Executive, e-commerce / FMCG company: ₹28,000–₹40,000 per month
These numbers are based on publicly available job postings. Companies filing hundreds of returns monthly — think Tally Solutions' accounting services arm, large retail groups, or logistics firms — specifically ask for portal experience in their JDs. Hands-on GSTR-3B work, especially in amnesty situations, is a differentiator you can legitimately highlight.

Your 7-Day Action Plan to Get Amnesty Filings Done
Day 1–2: Pull the client/employer list. Confirm GSTIN status for each. Note tax periods outstanding. Download GSTR-2B for each period from the portal.
Day 3: Gather sales data (GSTR-1 filed or raw invoice data), purchase registers, and bank statements. Reconcile outward supply figures.
Day 4: Prepare working files in Excel or Tally Prime. Compute ITC eligibility strictly as per GSTR-2B. Note any reversals needed.
Day 5: File returns in chronological order — oldest period first, because each period's ITC feeds the next. Pay tax dues via PMT-06 if cash ledger balance is insufficient.
Day 6: Verify late fees on the portal. Confirm they reflect the amnesty cap. Pay reduced late fees. Download all ARNs.
Day 7: Prepare a compliance summary for your senior or client: tax paid, late fee paid (pre-amnesty vs. post-amnesty saving), and ARN numbers for each period. This one-page summary is the kind of initiative that gets noticed in a first job.

One Mistake That Could Cost You the Amnesty Benefit
Filing the return after the amnesty deadline is the most avoidable error. The CBIC does not grant individual extensions — the window is fixed. Mark the deadline in your calendar the moment you read the notification. Set a reminder three days before. If a client is slow to share data, file a nil return by the deadline if necessary (confirm with your senior first — a nil filing is reversible in spirit via subsequent corrections, but liability suppression is not). The cost of missing the window is the full Section 47 late fee, which on multi-year defaults can run into tens of thousands of rupees per client.
