The GST Portal at gst.gov.in is the central nervous system of India's Goods and Services Tax system. Every GST-registered business in India must use this portal for registration, return filing, payment, and compliance. Yet for most business owners and entrepreneurs, the portal feels overwhelming — complex menus, confusing forms, and cryptic error messages.
This comprehensive guide — updated for 2026 — walks you through every major feature of the GST portal: from creating your first login to filing returns, checking ITC, making payments, and handling notices. By the end, you'll be confident navigating India's most important tax portal.
1. What is the GST Portal (gst.gov.in)?
The GST Portal, officially called the Goods and Services Tax Network (GSTN) portal, is the government-run digital platform that manages all GST-related activities for taxpayers in India. Launched on July 1, 2017, along with GST itself, the portal is managed by GSTN — a not-for-profit company set up by the Government of India.
The portal serves as a one-stop destination for:
- New GST registration applications
- Filing of all GST returns (GSTR-1, GSTR-3B, GSTR-9, etc.)
- Making GST tax payments via electronic cash/credit ledger
- Claiming and reconciling Input Tax Credit (ITC)
- Tracking application status using ARN
- Downloading GST registration certificates
- Filing amendments, cancellations, and revocations
- Responding to show cause notices and demand orders
- Generating e-Way Bills (linked to the ewaybill.nic.in portal)
GST Portal — Main Navigation
The portal has 6 main sections accessible from the top menu:

- Go to Services → User Services → View/Download Certificates

7. GST Return Filing — Complete Guide to GSTR-1, GSTR-3B & GSTR-9
Filing GST returns regularly is the most important ongoing compliance obligation. Here are the key returns:
Step-by-Step: How to File GSTR-3B
Login → Services → Returns → Returns Dashboard
Select the financial year and tax period (month). Click "Prepare Online" under GSTR-3B. The portal loads a pre-filled form based on your GSTR-1 and GSTR-2B data.
Fill Table 3.1 — Outward Supplies & Tax Liability
Enter total taxable value and tax (IGST, CGST, SGST) for: regular taxable supplies, zero-rated supplies (exports), nil-rated, and exempt supplies. This is your total output tax.
Fill Table 4 — ITC Available & Eligible
Enter ITC as per GSTR-2B. Separate into: ITC on inputs, capital goods, and input services. Also declare ITC reversals if any (used for personal/exempt purposes).
Compute Tax Payable & Make Payment
The portal auto-calculates tax payable = Output tax − ITC. Use Electronic Credit Ledger balance first, then create a challan for cash payment if required. Complete payment before filing.
Preview, Verify & File with DSC / EVC
Click "Preview Draft GSTR-3B" to review. Once satisfied, file using: DSC (for companies/LLPs) or EVC (OTP on registered mobile for proprietors/partnerships). Filing is final — no revision allowed.
⚠ Once filed, GSTR-3B cannot be revised — file carefully8. How to Check & Reconcile Input Tax Credit (ITC) on the GST Portal
ITC management is one of the most critical activities on the GST portal. Incorrect ITC claims can lead to notices and demand orders.
8.1 Viewing Your GSTR-2B (Auto ITC Statement)
- Login → Services → Returns → GSTR-2B
- Select the tax period and click "Generate/View"
- GSTR-2B shows ITC available from each supplier based on their GSTR-1 filings
- Download the detailed Excel report for reconciliation with your purchase register
8.2 ITC Reconciliation — Why It Matters
Since 2021, ITC can only be claimed in GSTR-3B if it appears in your GSTR-2B. If a supplier delays or doesn't file their GSTR-1, the ITC doesn't appear in your 2B — and you cannot claim it. This is why supplier compliance tracking is critical for every business.
8.3 Electronic Credit Ledger
- Login → Services → Ledgers → Electronic Credit Ledger
- Shows your available ITC balance (IGST, CGST, SGST separately)
- ITC can only be used to pay output tax — not late fees or penalties
- Unutilized ITC balance can be refunded if you have zero-rated supplies or inverted duty structure
9. How to Make GST Payments Online on the Portal
All GST tax payments are made through the GST portal by creating a challan. Here's the process:
Login → Services → Payments → Create Challan
Select the appropriate tax period. Enter amounts under each head: IGST, CGST, SGST/UTGST, CESS — and under each minor head: Tax, Interest, Penalty, Fee, or Others.
Select Payment Mode
Available modes: Internet Banking (immediate credit), NEFT/RTGS (for large amounts, credit in 1–2 hours), Over the Counter (at authorized bank branches — only up to ₹10,000), Debit/Credit Card (subject to charges).
Complete Payment & Save CIN
After payment, a Challan Identification Number (CIN) is generated. The amount reflects in your Electronic Cash Ledger immediately (for net banking/card) or within 2 hours (for NEFT/RTGS). Save the CIN for your records.
10. How to Amend / Modify GST Registration on the Portal
Any change in your business details must be updated on the GST portal by filing an amendment application. There are two types:
Core Field Amendments (Require Officer Approval)
- Change in legal business name
- Change in principal place of business (state change)
- Addition/deletion of partners or directors
Non-Core Field Amendments (Self-Approved)
- Change in mobile number or email
- Change in authorized signatory
- Addition of bank account
- Change in business address within same state
How to file: Login → Services → Registration → Amendment of Registration Core Fields / Non-Core Fields → Make changes → Submit with DSC or EVC
11. GST Cancellation & Revocation on the Portal
Voluntary Cancellation
If your business is closing, turnover falls below threshold, or you no longer need GST, you can apply for voluntary cancellation:
- Login → Services → Registration → Application for Cancellation of Registration
- Select reason (business discontinued, turnover below threshold, etc.)
- File all pending returns before applying — portal will block cancellation if returns are pending
- File final return GSTR-10 within 3 months of cancellation effective date
Revocation of Cancellation
If your GST was cancelled by the officer (for non-filing of returns), you can apply for revocation within 30 days of the cancellation order by filing all pending returns and paying dues.
12. How to Respond to GST Notices on the Portal
GST notices (show cause notices, demand orders, scrutiny notices) are sent through the portal. Here's how to access and respond:
- Login → Services → User Services → View Notices and Orders
- All notices issued by your GST officer appear here — check regularly
- Each notice has a due date for response — never miss it
- Click on the notice → Reply → Upload reply letter and supporting documents → Submit
- Keep a copy of your reply and acknowledgment
13. Common GST Portal Errors & How to Fix Them

| Error | Cause | Solution |

| OTP Not Received | Network issue or wrong mobile/email | Click "Resend OTP". Ensure Aadhaar-linked mobile is active. Try after 2 minutes. |
