GST Penalty Calculator, Challan Payment & Late Filing Guide 2026

GST Penalty Calculator, Challan Payment & Late Filing Guide (2026)

If you missed a GST return deadline or received a demand notice in 2026, the first thing you want to know is: how much do I actually owe? This guide answers that question immediately below, walks you through the new Section 74A penalty rules effective from FY 2024-25, and covers the complete process to create and pay a GST challan online or offline.

2026 Update: The Finance (No. 2) Act 2024 introduced Section 74A, which replaces the old Sections 73 and 74 for all tax periods from FY 2024-25 onwards. If your pending returns relate to FY 2024-25 or later, the penalty rules have changed. See the Section 74A breakdown below before paying.

Quick Answers: GST Penalties & Challans

• What is a GST penalty? A late fee charged under Section 47 of the CGST Act when a taxpayer files a GST return after the due date. The rate is ₹50 per day for returns with tax liability and ₹20 per day for nil returns, subject to a maximum cap. For fraud and tax evasion cases from FY 2024-25, the new Section 74A applies with a penalty ranging from 10% to 100% of the tax evaded.

• What is the GST penalty per day? ₹50 per day (₹25 CGST + ₹25 SGST) if you owe tax. For nil returns, it is ₹20 per day (₹10 CGST + ₹10 SGST).

• What is the GST penalty for non-filing of return? Late fees accumulate daily until the return is filed. After two consecutive missed periods, the GST portal blocks e-way bill generation. The department can also raise a best-judgment assessment with an 18% annual interest on unpaid tax.

• What is a GST challan? A GST challan (Form PMT-06) is the payment instrument generated on the GST portal to deposit tax, interest, penalty, or late fees. It carries a unique CPIN and stays valid for 15 days from creation.

• How to create a GST challan? Log in to the GST portal > Services > Payments > Create Challan. Enter your GSTIN, tax period, and amount under the correct head, choose your payment mode, and click Generate Challan. The CPIN appears immediately.

• How to check GST challan status? Go to Services > Payments > Challan History on the GST portal. Search by CPIN or date range. To check without logging in, use Services > Track Payment Status and enter the CPIN directly.

• Can I pay a GST challan without a login? Yes. On the GST portal, go to Services > Payments > Create Challan, enter your GSTIN manually without logging in, generate the challan, and complete payment via net banking. The credit reflects in your cash ledger automatically.

• What is Section 74A in GST? Section 74A replaces Sections 73 and 74 for tax periods from FY 2024-25 onwards. It sets a unified penalty of 10% of tax for non-fraud cases and 100% for fraud. The older two-track system no longer applies to recent periods.

2026 GST Penalty Updates: What Changed This Year?

Three significant shifts affect penalty calculations in 2026:

1. Section 74A is Fully Active

For all demand notices relating to FY 2024-25 and later, the GST department issues orders under the new Section 74A instead of the old Sections 73 or 74. The penalty structure is simpler: 10% of tax for genuine errors and 100% for fraud. If you received a demand notice for a recent tax period, verify which section it cites before responding.

2. Section 128A Amnesty is Closed

The Section 128A waiver scheme, which allowed taxpayers to pay only the principal tax for FY 2017-18 to FY 2019-20 and get full interest and penalty waived, had its absolute payment deadline on March 31, 2025. That window is now closed. If you missed it, the full demand including interest and penalties applies.

3. GSTR-1A Now Operational

The new GSTR-1A return, which lets you amend outward supply details after filing GSTR-1 but before filing GSTR-3B, is now an established part of the regular filing cycle. Filing GSTR-1A correctly drastically reduces the chance of ITC mismatches that trigger penalty notices.

GST Penalty in Detail: Rates, Caps, and Exemptions (2026)

GST law sets late fees under Section 47 of the CGST Act. The standard rates remain unchanged in 2026:

• Returns with tax liability: ₹50 per day (₹25 CGST + ₹25 SGST)

• Nil returns (zero tax payable): ₹20 per day (₹10 CGST + ₹10 SGST)

The maximum cap is generally ₹5,000 per return for most filers. While the government has issued various amnesty schemes in the past (including the Section 128A scheme that ended in 2025), if you have pending returns older than FY 2020-21, verify the current GST Council notifications before paying, as waiver windows open periodically.

GST Penalty Calculator: How to Calculate Your Fine

You do not need a separate app to check your liabilities. The calculation formula is straightforward:

$$\text{Total Penalty} = \text{Daily Rate} \times \text{Number of Days Late}$$

Example Calculation (2026):

Imagine you filed your GSTR-3B for March 2025 on June 15, 2025 (instead of the due date, April 20, 2025). The return is 56 days late.

• With Tax Liability: $56 \times 50 = \text{₹}2,800$

• For a Nil Return: $56 \times 20 = \text{₹}1,120$

GST Penalty List: Which Returns Attract Late Fees?

Late fees apply if you file any of the following returns after their official due dates:

• GSTR-1 (Outward supplies, monthly or quarterly)

• GSTR-1A (New amendment return, if filed late after the allowed window)

• GSTR-3B (Monthly or quarterly summary return)

• GSTR-4 (Composition scheme annual return)

• GSTR-9 & GSTR-9C (Annual return and reconciliation statement)

• GSTR-7 (TDS deductors)

Note: GSTR-2A and GSTR-2B are auto-populated system-generated returns and do not attract independent late fees. Conversely, GSTR-6 (Input Service Distributors) carries a separate penalty of ₹100 per day under CGST and ₹100 per day under SGST, capped at ₹5,000 each.

GST Penalty for Non-Filing of Return

If you completely ignore a return—even a nil return—the penalty keeps running daily with no automatic stop until it hits the statutory cap.

Additionally, the GST department can:

1. Issue a notice under Section 46 of the CGST Act.

2. Apply a best-judgment assessment under Section 62.

3. Block your e-way bill generation if returns are pending for two or more consecutive tax periods.

4. In 2026, GSTN’s AI-based compliance monitoring flags non-filers faster than ever, triggering automated notices within weeks.

5. Flag your GSTIN as non-compliant publicly, affecting how buyers view your compliance profile and impacting their Input Tax Credit (ITC) claims.

GST Penalty Under Section 74A (2026 Update)

Section 74A is the most crucial structural penalty change for taxpayers today. Introduced by the Finance (No. 2) Act 2024 and fully applicable to all tax periods from April 1, 2024 onwards, it replaces the old dual-track system of Section 73 (errors) and Section 74 (fraud).

Core Provisions of Section 74A:

• All demand proceedings for recent tax periods happen under a single section (Section 74A).

• Penalty for Non-Fraud Cases (genuine errors, oversights): 10% of the tax demanded.

• Penalty for Fraud Cases (willful misstatement, suppression): 100% of the tax demanded.

• Prosecution thresholds remain strict: criminal prosecution is possible where the tax evaded exceeds ₹2 crore.

What this means practically: The penalty depends entirely on what the officer concludes about your intent. A genuine calculation error could cost you just a 10% penalty if you cooperate and pay up on time. However, using fake invoices or missing turnover will quickly trigger the 100% rate.

Note: The older Section 74 still governs demands for FY 2023-24 and earlier periods. Do not confuse the two.

Penalty in GST Without Bill (No Invoice Cases)

Selling goods or providing services without issuing a valid GST invoice is a severe offense under Section 122 of the CGST Act. The penalty is the higher of:

• 100% of the tax evaded, OR

• ₹10,000

This is entirely distinct from a late filing fee. In 2026, the GST department's e-invoice system mandates coverage for businesses with turnover above ₹5 crore. Cross-matching of e-invoices with GSTR-1 is fully automated, meaning invoice mismatches instantly flag system-generated compliance alerts.

GST Penalty for Nil Return Late Filing

Many taxpayers assume that because no tax is due, there is no penalty for filing a late nil GSTR-3B. That is incorrect.

The late fee is ₹20 per day (₹10 CGST + ₹10 SGST) for nil returns, subject to a maximum cap of ₹500 per return. The GST portal's penalty calculator displays this fee automatically when you log in and attempt to clear a late nil return.

Section 128A Amnesty: Is It Still Available in 2026?

No. The Section 128A amnesty scheme, which allowed full waiver of interest and penalties for FY 2017-18 to FY 2019-20 on the condition that principal tax was paid, officially closed on March 31, 2025.

• If you paid before the deadline: Check whether your demand order has been officially dropped by visiting Services > User Services > View Notices and Orders.

• If you missed the deadline: The full demand with regular interest and penalties applies. Keep an eye out for future GST Council announcements in case a fresh amnesty window opens.

What Is a GST Challan?

A GST challan (Form PMT-06) is the absolute payment instrument used to deposit GST dues, late fees, interest, and penalties into the government treasury. You generate it on the GST portal (gstin.gov.in), and it remains valid for 15 days from the date of creation. Without a challan, there is no payment reference number, and your electronic cash ledger will not reflect the deposit.

How to Create a GST Challan in 2026 (Step-by-Step)

The generation process remains simple, now featuring UPI for fast tracking:

1. Log in to the GST portal (gstin.gov.in).

2. Navigate to Services > Payments > Create Challan.

3. Enter your GSTIN (or search by PAN if you are an unregistered applicant).

4. Enter the amount under the correct sub-head: Tax, Interest, Penalty, or Fees across CGST, SGST, IGST, or CESS.

5. Choose your payment mode: Net Banking, Debit Card, NEFT/RTGS, UPI (for amounts up to ₹1 lakh), or Over-the-Counter (OTC).

6. Click Generate Challan and download the 15-day valid CPIN.

👉 GST payment process explained

GST Challan Online Payment Modes

Once you generate the challan and get your CPIN, you can execute payment via:

• Net Banking: Directly via authorized banks (SBI, HDFC, ICICI, Axis, Kotak, etc.).

• Debit Card: Available directly at checkout.

• UPI: Ideal for small business owners; works instantly for challan amounts up to ₹1 lakh.

• NEFT/RTGS: Use the generated challan details to execute a bank transfer. Credit reaches your cash ledger within one working day.

GST Challan Payment Without Login

You can pay a GST challan without logging into your account—highly useful if you are paying on behalf of a client or clearing a sudden demand notice. Simply go to Services > Payments > Create Challan and type in your GSTIN manually. The portal allows you to complete net banking or UPI execution directly, mapping the CPIN back to your account ledger.

GST Challan Payment Offline

For over-the-counter payments (capped strictly up to ₹10,000 per challan):

1. Generate and print the challan with the CPIN online.

2. Visit an authorized bank branch.

3. Pay via cash or demand draft. The bank will stamp your receipt.

4. Note: For payments exceeding ₹10,000, offline cash payments are barred. You must use online modes or NEFT/RTGS.

Tracking and Downloading Your Challans

GST Challan Status Check

To check whether a payment has been fully processed:

• Log in and go to Services > Payments > Challan History.

• If the status stays stuck as "Initiated" for more than 24 hours, contact your banking partner with the CPIN number. Alternatively, track without logging in via Services > Track Payment Status.

GST Challan Download & History

Download your formal payment receipt via Services > Payments > Challan History > Select CPIN > Download. The downloaded PDF contains your CIN (Challan Identification Number), which serves as your conclusive legal proof of payment. The portal stores the last 6 months of data by default; use custom date filters for older records.

GST Penalty Payment Online: End-to-End Execution

Paying a penalty follows the exact sequence as paying normal tax:

1. Log in and create a challan.

2. Under the Fee and Penalty columns, fill in the exact amounts specified by the portal or your received notice.

3. Generate the challan and make the payment online.

4. Once credited to your Electronic Cash Ledger, make sure to actually offset the liabilities while submitting your final return or notice reply under the "Payment of Tax" screen. Merely adding money to the ledger does not automatically clear the penalty.
