Yes, you can dispute a charge, and your bank has a legal process to help you

If you see a charge on your checking account that you did not make or that was processed incorrectly, you can dispute it with your bank. Your bank is required by federal law to investigate the charge and either reverse it or explain why it stands. The process takes time — usually 10 business days for an initial investigation and up to 45 days for a full resolution — but you have real protection built into the system.

The key is starting the dispute quickly. Most banks give you 60 days from the date the charge appeared on your statement to report it. After that window closes, your options narrow significantly. The sooner you contact your bank, the sooner the investigation begins.

Key Takeaways

  • You have 60 days from the date a charge appears on your statement to report it to your bank, though reporting within 30 days is safer.
  • Your bank must acknowledge your dispute within 10 business days and complete an investigation within 45 days.
  • Contact your bank by phone, in writing, or through your online banking portal — written notice creates a record and is often fastest for disputes.
  • While the dispute is being investigated, your bank must return the disputed amount to your account if the charge appears unauthorized.
  • If your bank rules against you, you have the right to submit a written statement explaining your side, which stays in your file.

The difference between unauthorized charges and billing errors

Your bank treats two types of disputes differently, so knowing which one you have matters. An unauthorized charge is one you did not make and did not permit — someone used your card or account number without your consent. A billing error is a charge that was authorized but processed wrong: the amount is incorrect, the charge posted twice, the merchant charged you for something you returned, or the charge was posted to the wrong date.

Both are disputable, but the law protects you differently depending on which one you have. Unauthorized charges on a debit card are covered under the Electronic Funds Transfer Act, which limits your liability if you report within 60 days. Billing errors are covered under Regulation E, which requires your bank to investigate and correct them. The process is similar, but the timeline and your protection level differ slightly.

How to start a dispute with your bank

Contact your bank as soon as you notice the charge. You can dispute in three ways: by phone, in writing, or through your online banking portal. Calling is fastest for an when ready response, but sending a written notice — by mail, email, or through your bank's find message system — creates a paper trail that protects you if there is a disagreement later.

If you write, include your name, account number, the date of the charge, the amount, the merchant name, and a brief explanation of why you are disputing it. Keep a copy for your records. Your bank must acknowledge receipt of your dispute within 10 business days and tell you what happens next. Some banks will credit your account when ready while they investigate; others will wait for the investigation to conclude.

Do not wait for a statement to arrive in the mail. Dispute the charge as soon as you see it online or on a mobile alert. The 60-day clock starts from the date the charge posted to your account, not the date you receive your statement.

What happens during the investigation

Once you file a dispute, your bank contacts the merchant or the merchant's bank to ask for proof that you authorized the charge. The merchant has a set number of days — usually 10 to 20 — to respond with documentation. If they cannot produce a signed receipt, a PIN entry record, or other proof of authorization, the charge is typically reversed in your favor.

Your bank must complete the investigation within 45 calendar days. If they need more time, they can extend to 90 days, but they must notify you in writing and explain why. During this time, if the charge was unauthorized, your bank should have already returned the money to your account. If it was a billing error, they will correct it once they confirm the mistake.

You will receive a written explanation of the outcome, whether the dispute was upheld or denied. If denied, the letter will explain the reason — usually that the merchant provided proof of authorization or that the charge fell outside the dispute window.

What to do if your bank rules against you

If your bank decides the charge was valid, you have the right to submit a written statement — usually one page — explaining your side of the dispute. This statement becomes part of your permanent dispute file and travels with your account. It does not overturn the decision, but it creates a record that you contested the charge.

You can also ask your bank to provide the merchant's proof of authorization so you can review it yourself. Sometimes the documentation is unclear or does not match your account, and seeing it may help you decide on next steps. If the charge was made with a credit card rather than a debit card, you may have additional dispute rights through the credit card company, which operates under different rules.

Protecting yourself from future disputes

Review your checking account statements regularly — weekly if possible — rather than waiting for the monthly statement. Most banks let you see charges within one business day of posting through their website or app. The sooner you spot a problem, the sooner you can dispute it and stay well within the 60-day window.

Keep receipts from in-person transactions for at least 30 days. If a charge is disputed, the merchant may ask you to prove you made the purchase. A receipt with your signature or PIN confirmation is the strongest evidence you can provide. For online purchases, save your confirmation emails and order numbers.

If your debit card is lost or stolen, report it to your bank when ready. Your liability for unauthorized charges is limited to $50 if you report within two business days, but jumps to $500 if you wait longer. After 60 days, you may have no protection at all.

Frequently Asked Questions

What if the charge is from a scammer, not a real merchant?

Report it the same way — your bank will investigate and contact the merchant's bank. If the merchant account was fraudulent or the transaction routed through a payment processor, the bank may reverse the charge more quickly because there is no legitimate merchant to defend it. You should also report the scam to the Federal Trade Commission at reportfraud.ftc.gov.

Can I dispute a charge if I authorized it but changed my mind?

No. A dispute is for unauthorized charges or billing errors, not buyer's remorse. If you authorized a purchase and want your money back, contact the merchant directly to request a refund. If they refuse, you may have other options like a chargeback through a credit card, but a debit card dispute will not work.

How long does it take to get my money back?

If the charge is unauthorized, your bank should return the money within 10 business days while they investigate. If it is a billing error, the timeline depends on the complexity, but the investigation must finish within 45 days. Some banks are faster; check with yours about their specific timeline.

What if the merchant says I did authorize the charge?

Your bank will ask the merchant for proof — a signed receipt, PIN entry, or other documentation. If the merchant cannot produce it, the charge is reversed even if they claim you authorized it. If they do have proof, your bank will likely rule against you, but you can submit a written statement explaining your position.

Do I have to pay the disputed charge while the investigation happens?

No. If the charge appears unauthorized, your bank must return the money to your account within 10 business days. You do not have to pay it back unless the investigation concludes that the charge was valid and authorized.
