What is NACH and Why Does Money Get Deducted?
NACH (National Automated Clearing House) is RBI's system for automated recurring payments. When you sign up for EMI, insurance premium, SIP, OTT subscription or utility payment auto-pay, you give a NACH mandate. The company can then deduct money from your account on due dates without your approval each time.

Method 1 — Through Bank Net Banking
SBI: Net Banking → e-Services → SI / NACH Mandate → View and Cancel
HDFC: Net Banking → Accounts → Mandate Registration → Cancel
Axis Bank: Net Banking → Services → SI Mandate → Cancel Mandate
Method 2 — Visit Branch
Carry your passbook, ID proof and account number
Fill NACH mandate cancellation form at the branch
Submit original mandate if you have it
Get written acknowledgement of cancellation
Important: Give 30 days advance notice before cancelling a mandate. If you cancel abruptly, the next debit may still go through and you may face failed payment charges from the company. Also inform the company (lender, insurer, etc.) after cancelling so they can arrange alternate payment method.
How to Get Refund for Unauthorised NACH Debit
Step 1: Immediately call your bank helpline and report the unauthorised deduction
Step 2: File written complaint with your bank within 30 days
Step 3: Bank must resolve within 7 working days (RBI mandate)
Step 4: If not resolved — file NPCI grievance at npci.org.in
Step 5: Escalate to RBI Ombudsman at cms.rbi.org.in
Log into your bank's net banking or mobile app and look for Mandate Management or NACH/SI section. You can view all active mandates and cancel any of them online. Give 30 days notice to avoid failed payment charges. Also inform the company whose mandate you're cancelling so they can arrange alternate payment. If online cancellation isn't available, visit your home branch with ID proof.
Yes. Report the unauthorised deduction to your bank immediately — file a written complaint within 30 days. Under RBI guidelines, if NACH deduction was truly unauthorised (you never gave the mandate or it was already revoked), the bank must refund within 7 working days. If bank doesn't cooperate, file complaint at NPCI grievance portal or RBI CMS portal.
If NACH mandate is not properly cancelled, the company can continue to debit your account on due dates. Even if your account has insufficient funds, failed NACH attempts incur Rs 200-500 penalty per attempt from your bank. Always cancel mandates through the official bank channel and get written confirmation. Keep the cancellation acknowledgement for future disputes.
