You can block most charges through your bank, but the method depends on whether you authorized the charge in the first place
If a business is charging your checking account without your permission, you have several ways to stop it. The fastest is to contact your bank directly and request a block on that merchant or a stop payment on recurring charges. If you authorized the charge but want to cancel it going forward, you can also contact the business itself and ask them to stop billing you. The path you take depends on whether the charge was authorized, whether it is one-time or recurring, and how quickly you need it stopped.
Your bank can act within one to three business days for most requests. Stopping a charge that you never authorized is faster and stronger than canceling one you did authorize but now regret — the bank treats unauthorized charges as potential fraud and will investigate if the merchant disputes the block.
Key Takeaways
- Contact your bank immediately by phone, app, or online banking to report the charge and request a block on that merchant or a stop payment on recurring transactions.
- If you authorized the charge but want to stop future ones, contact the business directly first — most will cancel if you ask, and this is faster than involving your bank.
- Unauthorized charges can be disputed as fraud; your bank will investigate and may reverse the charge while they look into it, but you must report it within 60 days of the statement date.
- For recurring charges you authorized, your bank can place a stop payment that lasts a set number of payments or indefinitely, depending on the bank.
- Some banks let you block entire merchant categories (like "subscription services" or "online retailers") through their app, which stops all charges from that type of business.
How to block a charge through your bank
Call your bank's customer service line or log into your online banking portal and look for "stop payment," "block merchant," or "dispute transaction." Most banks have a phone line available 24/7 for fraud reports. Have your account number, the merchant's name, the charge amount, and the date of the charge ready when you call.
Tell the bank whether this is a one-time charge or a recurring subscription. If it is recurring, ask the bank to place a stop payment order that blocks all future charges from that merchant. Most banks can do this immediately over the phone, though it may take one to three business days to show up in your account. Some banks charge a small fee (typically $25 to $35) for a stop payment order, though many waive the fee if you report fraud.
If you want to block an entire category of merchants — for example, all subscription services or all online retailers — some banks offer merchant category blocking through their mobile app. Check your bank's app settings under "controls," "limits," or "security" to see if this feature is available. This is useful if you have been charged by multiple businesses in the same category and want to prevent future charges across the board.
Stopping charges you authorized but no longer want
If you signed up for a service or gave the business permission to charge you, the fastest way to stop the charge is to contact the business directly. Call their customer service number, email their support address, or log into your account on their website and look for a "cancel subscription" or "manage billing" option. Ask them to stop charging your account and request written confirmation (email is fine) that the cancellation is complete.
Most businesses will cancel immediately when you ask. Some may ask you to confirm your identity or account number, and some may offer a discount to keep you as a customer — you can accept or decline. Once the business confirms the cancellation, the charges should stop within one to two billing cycles. If charges continue after the business says they have canceled, then contact your bank and report it as unauthorized.
Do not assume the charge will stop on its own. Many subscriptions and recurring services require you to actively cancel; they do not expire automatically. Check your bank statement for the next two months after you cancel to make sure the business honored your request.
Disputing unauthorized charges as fraud
If you did not authorize the charge and the business will not stop charging you, report it to your bank as fraud or an unauthorized transaction. Under federal law, your bank must investigate within 30 days and either reverse the charge or explain why it was authorized. During the investigation, the bank will usually remove the charge from your account temporarily so you are not out the money while they look into it.
You must report the unauthorized charge within 60 days of the date it appears on your bank statement. If you wait longer, your bank may not be required to refund you. Keep records of any communication with the business — emails, chat transcripts, or notes from phone calls — because the bank will ask for proof that you did not authorize the charge.
If the bank finds that you did authorize the charge (for example, if you signed up for a free trial and the business charged you when the trial ended), they may not reverse it. In that case, your only option is to ask the business to refund you or to place a stop payment order with your bank to prevent future charges.
Blocking charges from a specific merchant
Some banks let you block all charges from a specific business without canceling the service. This is useful if you want to keep an account open but prevent the business from charging you. Log into your online banking or call your bank and ask to place a merchant block on that business. Provide the merchant's name and the charge amount if possible.
A merchant block tells the business's payment processor that your bank will not accept charges from that merchant. The business will see the charge declined and may contact you to ask why. If the business is one you authorized but no longer want to pay, a merchant block is a backup to canceling directly — it ensures the charge cannot go through even if the business ignores your cancellation request.
Be aware that a merchant block may prevent legitimate charges if the business uses multiple payment processors or if you later want to make a purchase from them. If you think you might use the business again, canceling the subscription directly is cleaner than blocking the merchant.
What happens if the business disputes the block
If you report a charge as unauthorized and the business disputes your claim, your bank will ask you for evidence. Provide any documentation showing you did not authorize the charge: screenshots of your account settings, emails from the business, or records of your cancellation request. If you have no record of ever signing up for the service, tell the bank that.
The bank will contact the business and ask them to prove you authorized the charge. If the business cannot provide proof — a signed agreement, an email confirmation, or a record of your account setup — the bank will usually side with you and keep the charge reversed. If the business does provide proof that you authorized it, the bank may put the charge back on your account, and you will need to resolve it with the business directly (by requesting a refund or canceling the service).
This process typically takes 30 to 60 days. During that time, the charge remains off your account. If the bank rules against you, they will notify you in writing and explain why.
Preventing future unauthorized charges
After you stop a charge, take steps to prevent the business from charging you again. Change your password on any account you have with that business, or delete your payment method from their website if you no longer plan to use them. If the business has your debit card number, consider requesting a new debit card from your bank — this will invalidate the old number and prevent the business from charging it.
You can also set up transaction alerts through your bank's app so you are notified immediately when any charge is posted to your account. This lets you catch unauthorized charges quickly and report them before they pile up. Some banks let you set alerts for charges above a certain amount, charges from specific merchants, or all transactions.
If the business continues to attempt charges after you have blocked them and reported them as fraud, contact your bank again and ask about filing a formal complaint. You can also file a complaint with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov if your bank is not helping you stop the charges.
Frequently Asked Questions
How long does it take for a stop payment to go into effect?
Most banks process a stop payment order within one to three business days. Some banks can block a charge immediately over the phone, but it may take a few days to show up in your account system. If a charge posts before the stop payment takes effect, contact your bank and ask them to reverse it as a duplicate or unauthorized charge.
Will the business know I blocked them?
Yes, the business will see that the charge was declined when they try to process it. They may contact you to ask why or to try to collect the money another way. If you want to avoid contact, do not respond, or send a brief email saying you no longer authorize charges to your account.
Can I block a charge if I authorized it but forgot about it?
Yes, but the process is different. Contact the business first and ask them to cancel. If they refuse or if charges continue after you cancel, contact your bank and place a stop payment order. You cannot report it as fraud if you authorized it, but your bank can still block future charges.
What if my bank refuses to block the charge?
If your bank says you authorized the charge and will not block it, ask them to explain what proof they have. If you genuinely did not authorize it, ask to speak to a supervisor or file a formal dispute. You can also file a complaint with the CFPB if your bank is not responding to your request.
Do I need to cancel the service before asking my bank to block it?
No. You can ask your bank to block the merchant at any time, whether or not you have canceled with the business. However, canceling directly with the business is usually faster and cleaner, so try that first if you have an active account with them.
