Your core responsibilities as a checking account holder
When you open a checking account, you take on specific duties that the bank expects you to follow. These are not optional—they are part of the contract you sign when you open the account. The main ones are: keeping your balance accurate, reporting fraud or errors within the time limits the bank sets, paying overdraft fees if you spend more than you have, and following the bank's rules about how you use the account.
The bank has responsibilities too—they must keep your money safe, process your checks and transfers correctly, and tell you about changes to their fees or terms. But your side of the deal is to manage your account responsibly and stay on top of what's happening in it.
Key Takeaways
- You must monitor your balance regularly and report any unauthorized transactions or errors to your bank within 30 to 60 days, depending on the type of error.
- You are responsible for overdraft fees if you spend more money than you have in the account, unless you opt out of overdraft coverage.
- You must follow the bank's rules about account use, including not depositing counterfeit checks or using the account for illegal activity.
- You are expected to keep your account information secure and notify the bank immediately if your debit card or login credentials are compromised.
- You must read and understand the account agreement and fee schedule the bank provides, and keep track of any changes they announce.
Monitoring your balance and transactions
You are responsible for knowing how much money is in your account at all times. This means checking your balance regularly—through your bank's website, mobile app, or by calling their customer service line. If you do not track your balance, you risk overdrawing the account and paying fees, even if the bank could have prevented the overdraft.
You must also review your transactions as they post. Look for charges you did not make, transfers that went to the wrong place, or deposits that never showed up. The sooner you spot a problem, the easier it is to fix. Most banks send you a statement each month (or make one available online), and you should read it carefully.
Reporting fraud and errors within the deadline
If you see a transaction you did not authorize—a fraudulent charge, a check forged in your name, or a transfer someone else made—you must report it to the bank. The law gives you a window to do this, and it matters. For unauthorized debit card charges, you have 60 days from the date the statement was sent to you. For checks and other errors, the deadline is also typically 60 days, though some banks allow longer.
If you miss the deadline, the bank is not required to refund you. Report the problem in writing (email, secure message through your bank's app, or a letter) so you have a record. The bank will investigate and either refund you or explain why they will not. Keep copies of everything you send them.
Understanding and paying overdraft fees
An overdraft happens when you try to withdraw or spend more money than you have in the account. If your bank allows it, they will cover the transaction and charge you a fee—usually $25 to $35 per overdraft, though this varies by bank. Some banks charge multiple fees in a single day if you overdraw several times.
You have the right to opt out of overdraft coverage, which means the bank will simply decline transactions that would overdraw your account instead of covering them and charging you. If you opt out, you will not pay overdraft fees, but your card or check may be declined at the point of sale. You can change this setting at any time by contacting your bank.
Either way, the overdraft fee is your responsibility. The bank is not breaking the law by charging it—they are following the terms you agreed to when you opened the account.
Keeping your account information secure
You are responsible for protecting your account credentials: your username, password, PIN, and debit card number. Do not share these with anyone, even if they claim to be from the bank. Banks will never ask you for your password or PIN through email, text, or phone call.
If your debit card is lost or stolen, or if you suspect someone has your login information, contact your bank immediately. The sooner you report it, the sooner they can freeze the card and limit your liability for fraudulent charges. If you wait, you may be responsible for more of the unauthorized transactions.
Use strong, unique passwords for your online banking account. Do not use the same password across multiple websites. If your bank offers two-factor authentication (a second verification step, like a code sent to your phone), turn it on.
Following the bank's account rules and restrictions
Your account agreement spells out what you can and cannot do with the account. You cannot deposit counterfeit checks, use the account to receive money from illegal activity, or allow someone else to use your account as if it were theirs. You also cannot repeatedly overdraw the account or ignore the bank's attempts to collect overdraft fees.
If you violate these rules, the bank can close your account without warning and may report you to ChexSystems or Early Warning Services, which are banking history databases. Being listed in these systems makes it hard to open a new account at another bank for several years.
Read your account agreement when you open the account, and ask the bank to explain anything you do not understand. The rules are usually straightforward, but knowing them upfront prevents problems later.
Staying informed about fee changes and policy updates
Banks can change their fees, interest rates, and policies. They are required to notify you in advance—usually 30 days—before most changes take effect. These notices often come by mail or email, or they may be posted on the bank's website. You are responsible for reading them.
If you do not like a change—for example, if the bank is adding a monthly maintenance fee—you have the right to close the account and move to a different bank. But you have to act before the change takes effect. If you do nothing, you are accepting the new terms.
Some banks also change their terms of service or update their privacy policies. These updates are usually less dramatic than fee changes, but they still affect how your account works and how the bank handles your information. Check your email and your bank's website regularly so you do not miss these announcements.
Frequently Asked Questions
What happens if I do not report a fraudulent charge within 60 days?
The bank is not required to refund you if you report it after the deadline. You may still lose the money. The 60-day window starts from the date your statement was sent, not from the date the charge appeared. Mark your calendar or set a phone reminder to check your statements promptly.
Can the bank close my account without telling me?
Yes. Banks can close accounts for repeated overdrafts, suspected fraud, or violation of the account agreement. They usually give you notice and time to withdraw your money, but they are not required to in all cases. If your account is closed, you may be reported to ChexSystems, which affects your ability to open accounts elsewhere.
Am I responsible for paying overdraft fees if the bank made a mistake?
No. If the bank processed a transaction incorrectly and caused the overdraft, you should report it as an error. The bank will investigate and refund the overdraft fees if they find they were at fault. Keep records of the transaction and your communication with the bank.
Do I have to use online banking or a mobile app?
No. You can monitor your account by phone, in person at a branch, or by mail. However, online and mobile banking make it much easier to check your balance and spot problems quickly. Most banks do not charge extra for these services, so using them is a practical way to meet your responsibility to monitor your account.
What should I do if I think someone else is using my account?
Contact your bank immediately by phone. Tell them you suspect unauthorized access and ask them to freeze the account or change your login credentials. Follow up in writing with a description of what happened. The bank will investigate and may refund unauthorized transactions, but only if you report it promptly.
