Adding a bank account to your GST profile is one of the first tasks after registration — and one of the most common sources of errors. Missing or incorrect bank details can delay your GST refunds, trigger notices, and in some cases restrict return filing.
This guide covers the complete process with every step explained clearly, including what documents you need, mistakes that cause rejection, and how to fix common errors on the portal.
Who Needs to Add a Bank Account in GST?
You need to add bank details on the GST portal if:
- You just completed fresh GST registration and haven't added bank details yet
- You want to add a new or secondary business bank account
- Your existing account was closed, and you need to replace it
- Your refund got rejected due to incorrect bank details
The GST portal allows up to 10 bank accounts under a single GSTIN, and one can be marked as the primary account for refunds.
Documents Required
Before you start, keep these ready:
- Active GSTIN and login credentials
- Business bank account number and IFSC code
Any one of the following as proof:
- Cancelled cheque (must show account number, IFSC, and business name)
- First page of passbook
- Bank statement (not older than 3 months)
- Access to DSC or registered mobile number for OTP verification
Important: The name on the bank document must match your GST registration name. Even a minor mismatch (e.g., "Pvt Ltd" vs "Private Limited") can cause rejection.
Step-by-Step: How to Add Bank Account in GST Portal?
Step 1: Log In to the GST Portal
Visit services.gst.gov.in and log in using your GSTIN/username, password, and captcha.
Step 2: Select Amendment of Registration (Non-Core Fields)
After logging in:
Services → Registration → Amendment of Non-Core Registration Fields
Non-core fields are details that can be changed without GST officer approval — bank account is one of them.
Step 3: Click on the "Bank Accounts" Tab
On the amendment page, you will see multiple tabs. Click Bank Accounts.
If you have already added accounts, they will appear here. To add a new one, click Add New.
Step 4: Enter Your Bank Details
Fill in the following fields carefully:
- Account Number – Enter and confirm — no copy-paste errors
- IFSC Code – 11-character code (Bank name auto-fills)
- Account Type – Current (recommended for businesses)
- Branch Name – Auto-fills after IFSC
Pro tip: Type the account number manually both times instead of copy-pasting. Copy-paste errors are the #1 cause of bank detail rejection on GST.
Step 5: Upload Supporting Document
Upload a scanned copy of your cancelled cheque, passbook, or bank statement.
File requirements:
- Format: PDF, JPEG, or PNG
- Size: Maximum 1 MB
- The document must clearly show: account number, IFSC code, and account holder name
Step 6: Verify and Submit
Scroll to the verification section. Select the Authorised Signatory from the dropdown.
Choose your verification method:
- DSC – If your GST registration uses a Digital Signature Certificate
- EVC – OTP sent to your registered mobile number and email
After verification, click Submit.
Step 7: Save Your ARN
You will obtain an ARN (Application Reference Number) following submission. This is your tracking ID.
The bank account is typically validated within 1–3 working days. You can track the status at:
Services → Registration → Track Application Status → Enter ARN
What Happens After You Submit?
Many users don't know what happens next — and then panic when they see a delay. Here's what the process looks like after submission:
- ARN generated – Immediate confirmation
- Penny drop verification – GST system sends ₹1 to verify the account is active (this is automated)
- Bank account validated – Usually within 24–72 hours
- Status updated – Visible in your profile under the Bank Accounts tab
If the penny drop fails (account inactive, name mismatch), the account will show as "Not Validated", and you will need to resubmit with corrections.
How to Change or Update an Existing Bank Account
If you need to replace an old account or correct bank details:
- Log in to the GST portal
- Services → Enrollment → Monitor Application Status → Input ARN
- Click the Bank Accounts tab
- Click the edit icon next to the account you want to change
- Update details, upload new document
- Verify and submit
The old account remains visible until the new one is validated.
5 Common Errors and How to Fix Them
These are the actual reasons most bank addition requests get rejected or remain unvalidated:
Error 1: Name Mismatch
Problem: The name on the cancelled cheque doesn't exactly match the GST-registered business name. Fix: Use a bank document that shows the full legal name exactly as registered, or request a name correction at your bank first.
Error 2: Wrong Account Number (Copy-Paste Error)
Problem: Users copy-paste their account number, and a trailing space or missing digit causes a mismatch. Fix: Always type both entries manually and cross-check with your cheque leaf.
Error 3: Savings Account Instead of Current Account
Problem: GST refunds are processed to current accounts. Savings accounts may cause refund delays. Fix: Open a current account for your business and link that instead.
Error 4: Blurry or Cropped Document Upload
Problem: The uploaded passbook image is too dark, partially visible, or the IFSC is cut off. Fix: Upload a clear, full-page scan. All three details — name, account number, IFSC — must be visible.
Error 5: OTP Expired Before Submission
Problem: Users take too long to fill out the form, and the OTP expires before they click Submit. Fix: Keep all details ready before requesting OTP. Complete the submission within 10 minutes.
Can You Add a Personal Bank Account?
Yes, temporarily. If your business account is not yet opened, you can add a personal account and update it later once the business account is ready.
However, this is not recommended for the long term because:
- GST refunds to personal accounts may raise scrutiny
- Account name mismatches are common with personal accounts under a business GSTIN
Frequently Asked Questions
Q1. Is it mandatory to add a bank account in the GST portal?
While it is not strictly mandatory at the time of registration, it becomes essential for refund processing and smooth return filing. If you claim an Input Tax Credit refund without valid bank details, it will be rejected. Most GST officers also flag registrations with missing bank details during scrutiny. It is best to add it immediately after registration.
Q2. How many bank accounts can be added under one GSTIN?
You can add up to 10 bank accounts under a single GST registration. One account can be designated as the primary account for refunds. This is useful for businesses that handle transactions across multiple banks or operate in different states under the same GSTIN.
Q3. What documents are accepted as bank proof on the GST portal?
The portal accepts a cancelled cheque, the first page of your passbook, or a recent bank statement (not older than 3 months). All documents must clearly show your business name, account number, and IFSC code. Blurry or cropped documents are rejected during backend verification.
Q4. Why is my bank account showing "Not Validated" after submission?
This usually happens because the penny drop verification failed. Common reasons include: the account is inactive or closed, the name on the account does not match GST records, or the account type is not supported. Check the account status with your bank and resubmit with a fresh document.
Q5. Can I add a savings account instead of a current account?
Yes, you can add a savings account. However, most businesses are advised to use a current account for GST purposes. Refunds processed to savings accounts are slower and may face restrictions depending on the bank and transaction limits.
Q6. How long does bank account validation take on GST portal?
In most cases, the bank account is validated within 1 to 3 working days through an automated penny drop process. If it is not validated after 3 days, check your ARN status on the portal. If it shows "Pending," wait another day. If it shows "Rejected," resubmit with corrected details. In some cases restrict return filing or trigger cancellation of your GST registration
Q7. What happens if I enter the wrong account number by mistake?
Your bank details will fail the penny drop validation and show as "Not Validated." You will need to go back to the amendment section, delete the incorrect entry, and add the correct account number again. No penalty is applied for correction.
Q8. Can I delete a bank account after adding it?
Yes. Go to Services → Registration → Amendment of Non-Core Fields → Bank Accounts, and click the delete icon next to the account. However, you cannot delete the last remaining account if no other account is added. The portal requires at least one bank account for active registrations.
Q9. Do I need a DSC to add bank account details?
Not necessarily. If your GST registration supports EVC (Electronic Verification Code), you can verify using an OTP sent to your registered mobile number. DSC is required only if your GSTIN is registered as a company or LLP that mandates a digital signature for amendments.
Q10. Can I add a joint bank account in the GST portal?
Yes, a joint account can be added as long as the primary account holder's name matches the GST-registered business name. If the primary name on the joint account belongs to a different person, it may fail validation. In such cases, use an account where the business name or authorized signatory name appears first.
