Every GST-registered business in India must add a bank account in the GST portal within 45 days of receiving its GST registration certificate. This is not optional. Under Rule 10A of the Central Goods and Services Tax Rules, 2017, failure to furnish bank account details within the prescribed deadline triggers a show cause notice, suspension of the GSTIN, and ultimately cancellation of the GST registration under Rule 21(d).How to Add Bank Account in GST Portal is a mandatory compliance step for every GST-registered business in India.
A manufacturer in Coimbatore received his GSTIN in March and assumed the bank account could be added whenever it was convenient. By the end of the sixth week, his GSTIN was suspended. He could not issue invoices, file GSTR-1, or claim Input Tax Credit. His bank account had been ready since week two. He simply had not navigated to the right section of the portal to complete the filing. The reactivation took nine days and required a written reply to a show cause notice.
This guide covers the complete process of how to add bank account in GST portal in 2026: the legal mandate under Rule 10A, who is exempt, the consequences of non-compliance, the step-by-step process, the 2026 bank validation update, documents required, how to add multiple accounts, and common errors with fixes.
Why You Must Add Bank Account in GST Portal
Adding a bank account in the GST portal serves three compliance purposes under the CGST Act, 2017.
First, it ensures that GST refunds are processed into a verified, authenticated account. Without a linked and validated bank account, no refund can be credited to the business.
Second, it allows the GST system to verify that the registered business is a legitimate operating entity with a real bank account in its name. This is part of the government’s anti-fraud architecture introduced through Rule 10A via Notification No. 31/2019 dated June 28, 2019.
Third, for e-invoicing and e-way bill generation, a validated bank account is increasingly required as the GSTN links its compliance modules. The GSTN Advisory dated November 20, 2025, issued by the Goods and Services Tax Network, urgently reminded all registered taxpayers to complete bank account validation and to use the non-core amendment route for any updates, citing integration of NPCI-based real-time bank validation across the portal in 2026.
Rule 10A of CGST Rules, 2017: The Legal Mandate
Rule 10A was inserted into the Central Goods and Services Tax Rules, 2017 through Notification No. 31/2019 dated June 28, 2019 by the Central Board of Indirect Taxes and Customs (CBIC). It mandates that every registered person must furnish details of their bank account, in the name and PAN of the registered person, on the GST portal within 45 days of the grant of registration or before the due date of filing of the first outward supply return under Section 37 of the CGST Act, whichever is earlier.
The bank account submitted must be in the name of the registered person as it appears in the GST registration certificate. A bank account in the name of a partner, director, or any other individual, even if authorised, is not accepted under Rule 10A.
Who Is Exempt from Rule 10A
Two categories of registrants are exempt from the Rule 10A requirement to add bank account in GST portal:
- Persons who have obtained registration as a Tax Deductor at Source under Rule 12 read with Section 51 of the CGST Act, 2017.
- Persons who have obtained registration as a Tax Collector at Source under Rule 12 read with Section 52 of the CGST Act, 2017.
All other registered persons, including regular taxpayers, composition taxpayers, and persons registered under the Reverse Charge Mechanism, must comply with Rule 10A within the prescribed 45-day window.6
Consequences of Non-Compliance
The consequences of failing to add a bank account in the GST portal within 45 days are graduated and serious.
The GSTIN is first suspended under Rule 21A of the CGST Rules, which prevents the taxpayer from filing GSTR-1, claiming Input Tax Credit, generating invoices, or creating e-way bills.
If the bank account is still not furnished after suspension and the taxpayer does not respond satisfactorily to the show cause notice issued by the GST officer, the registration is liable to be cancelled under Rule 21(d) of the CGST Rules, inserted via Notification No. 31/2019.
Reactivation of a suspended GSTIN requires filing a reply to the show cause notice, adding the bank account on the portal, and waiting for the GST officer to revoke the suspension. The reactivation timeline varies from a few days to several weeks depending on jurisdiction.
Prerequisites Before You Add Bank Account in GST Portal
Before starting the process to add bank account in the GST portal, keep the following ready:
Active GSTIN and login credentials for the GST portal.
The business bank account number and IFSC code. The account must be in the name of the registered business or registered person as it appears on the GST registration certificate. Businesses wondering how to add bank account in GST portal should ensure that the bank account is active, PAN-linked, and supported by valid proof before starting the amendment process.
A scanned copy of one of the following: a cancelled cheque with the taxpayer’s name and account number pre-printed on it, the first page of the bank passbook clearly showing the account holder’s name and account number, or a bank statement with the account holder details.
The scanned document must be in PDF, JPEG, or PNG format and must not exceed 1 MB in size.
Digital Signature Certificate (DSC), E-Sign (Aadhaar-based), or Electronic Verification Code (EVC) for submission of the amendment.
An active mobile number and email registered with the GST portal, as the GSTN sends validation notifications to these after the bank account is processed.
How to Add Bank Account in GST Portal: Step-by-Step Process
Step 1: Log In to the GST Portal
Visit the official GST portal at https://www.gst.gov.in and log in using your GSTIN and password. Complete the OTP verification on the registered mobile number if prompted.
Step 2: Navigate to Amendment of Non-Core Fields
From the main dashboard, click on Services, then Registration, and then Amendment of Registration Non-Core Fields. Bank account details are classified as a non-core field under the CGST Rules. This means the amendment does not require approval from a GST officer and takes effect upon successful submission.
Step 3: Open the Bank Accounts Tab
On the Amendment of Registration Non-Core Fields page, locate the Bank Accounts tab. Click on it to view existing bank accounts, if any, and to add a new account.
Step 4: Enter Bank Account Details
Click on Add New. Enter the following details accurately: Account Number, re-enter Account Number for confirmation, IFSC Code, Account Type (Savings, Current, Cash Credit, or Other), and Bank Name and Branch (auto-populated on entering the IFSC code using the Get Address function). Verify that the account holder name displayed matches the name in the GST registration exactly.
Step 5: Validate the Bank Account
Click on Validate Account Details. In 2026, the GST portal performs real-time validation through NPCI and core banking integration, checking account number, IFSC, account holder name, and PAN linkage. This step is mandatory. Banks supporting NPCI return results within minutes; others may take a few hours and show Pending status.
Step 6: Upload the Supporting Document
After validation, upload one of the accepted documents: a cancelled cheque with the taxpayer’s name pre-printed, the first page of the passbook, or a bank statement showing the account holder details. The file must be in PDF, JPEG, or PNG format and must not exceed 1 MB.
Step 7: Save the Bank Account Details
Click Save to record the bank account entry in the amendment form. Multiple accounts can be added in the same session before submission. Up to 10 bank accounts can be registered under a single GSTIN.
Step 8: Verify and Submit the Amendment
Go to the Verification tab within the amendment form. Select the authorised signatory from the dropdown. Submit the amendment using one of the three available methods: DSC (Digital Signature Certificate, class 3 for companies and LLPs), E-Sign (Aadhaar OTP-based for individuals), or EVC (OTP sent to registered mobile number).
Once submitted, the ARN is generated and sent to the registered email and mobile. Bank account details update on the portal within 15 minutes. GSTN sends the validation status (Success, Failure, Success with Remark, or Pending) to the registered email and mobile.
How to Add Bank Account During New GST Registration
For new GST registration applicants, bank account details can be furnished in Part B of Form GST REG-01. Enter the account number, IFSC code, account type, and upload the required bank proof at this stage.
If the business bank account is not yet open at the time of applying, the Rule 10A framework allows bank details to be furnished after registration within the 45-day window. This resolves the earlier circular dependency where a bank account was needed to get GST registration and GST was needed to open a bank account.
Documents Required to Add Bank Account in GST Portal
Three types of documents are accepted to add a bank account in the GST portal. Only one needs to be uploaded per bank account entry.
Cancelled cheque: The cheque leaf must have the account holder’s name and account number pre-printed. A handwritten name is not accepted.
Bank passbook first page: Must clearly show the account holder’s name, account number, IFSC code, and branch details.
Bank statement: The first page must show the account holder’s name, account number, IFSC code, and branch. Internet banking downloads in PDF format are accepted.
The account holder’s name must exactly match the name in the GST registration. All documents must be in PDF, JPEG, or PNG format with a maximum file size of 1 MB.
How to Add Multiple Bank Accounts and How to Update Existing Details
Up to 10 bank accounts can be registered under a single GSTIN. To add another account, follow the same path: Services, Registration, Amendment of Non-Core Fields, Bank Accounts, Add New.
To modify an existing entry, click Edit instead of Add New. Update the details, re-validate, upload the document, and submit using DSC, E-Sign, or EVC.
To delete an account, select it and click Delete. At least one valid bank account must remain on the portal at all times. Bank mergers, account closures, or changes in operating banks are common reasons for using the non-core amendment route to update bank details.
Common Errors When You Add Bank Account in GST Portal and How to Fix Them
Validation Failure due to Name Mismatch: The account holder name in the bank’s records does not exactly match the name in the GST registration. Fix: Check whether the name in the GST certificate matches the PAN, which is linked to the bank account. Request the bank to update the account name to match the PAN-linked name if necessary.
Invalid IFSC Code: The IFSC code entered does not correspond to the account’s branch or is outdated due to a bank merger. Fix: Verify the current IFSC code on the RBI website or directly with the bank. Post-merger IFSC codes are different from pre-merger codes.
File Size Exceeds 1 MB: The scanned document uploaded is too large. Fix: Compress the PDF or reduce the image resolution of the JPEG before uploading. Most free online PDF compressors or image resizers bring the file under 1 MB.
DSC or EVC Failure: Clear browser cache, use Chrome or Firefox, and retry. For DSC errors, confirm the token driver is updated and the certificate is not expired.
Pending Validation Status for Extended Period: The bank account shows as Pending for Validation beyond 48 hours. Fix: Check the bank account status under the Bank Account Status tab in the dashboard. If still pending after 48 hours, contact the GSTN helpdesk or raise a ticket on the portal.
