Bank of America offers overdraft protection through linked accounts and overdraft lines of credit, but you must set it up yourself — it does not turn on automatically.

Bank of America has two main ways to cover overdrafts. The first is overdraft protection, which links your checking account to a savings account, money market account, or credit line so transfers happen automatically when you go negative. The second is their standard overdraft service, which lets transactions go through even without funds, then charges you a fee. You choose which one you want, and the choice matters because the costs are very different.

The key difference: overdraft protection prevents the overdraft from happening in the first place by moving money over. Standard overdraft service lets the overdraft happen, then charges you for it. Bank of America does not enroll you in overdraft protection by default — you have to request it through your account settings or by calling their customer service line.

Key Takeaways

  • Bank of America's overdraft protection links your checking account to another account you own so money transfers automatically when you would go negative.
  • You must turn on overdraft protection yourself; Bank of America does not enable it automatically when you open an account.
  • Overdraft protection can draw from a savings account, money market account, or a Bank of America credit line, depending on what you set up.
  • If you do not set up overdraft protection, standard overdraft fees apply when transactions post against insufficient funds.

How to set up overdraft protection at Bank of America

Log into your Bank of America online account or mobile app and go to the account settings for your checking account. Look for the overdraft protection or overdraft options section — the exact name varies slightly depending on whether you are using the website or app. Select the account you want to link (savings, money market, or credit line) and confirm the setup.

If you prefer to do this over the phone, call Bank of America's customer service number on the back of your debit card. A representative can walk you through which accounts you have available to link and set up the protection in real time. The process usually takes a few minutes.

Once overdraft protection is active, Bank of America will transfer money from your linked account to your checking account in increments (usually $100 at a time) whenever a transaction would cause an overdraft. You pay no fee for the transfer itself, but if you are drawing from a savings account, you may eventually hit federal limits on how many transfers you can make per month.

What happens if you link a savings account versus a credit line

If you link a savings account or money market account, Bank of America moves your own money over when needed. There is no interest charge, but you are using funds you may have set aside for emergencies or goals. Federal law limits you to six transfers per month from a savings account (including overdraft protection transfers), so if you hit that limit, the overdraft protection stops working and you fall back to standard overdraft fees.

If you link a Bank of America credit line or credit card, the transfer is treated as a cash advance. You pay interest on the amount borrowed, starting immediately, at the cash advance rate (which is usually higher than the regular purchase rate). This option works if you have exhausted your savings but have available credit, though the interest cost adds up quickly if you do not pay it back right away.

Standard overdraft fees if you do not use overdraft protection

Bank of America charges an overdraft fee each time a transaction posts against insufficient funds. The fee amount varies by account type and has changed over time, so check your account agreement or call to confirm the current fee for your specific account. The fee applies per transaction, not per day, so multiple transactions in one day can mean multiple fees.

Bank of America also has a daily overdraft limit — they will not let your account go more than a certain amount negative, even if you have overdraft service turned on. Once you hit that limit, further transactions are declined. This is different from overdraft protection, which prevents the negative balance from happening at all.

When overdraft protection does not work

Overdraft protection only covers transactions that post to your account — typically debit card purchases, checks, and ACH transfers. Some transactions, like wire transfers or ATM withdrawals, may not be covered by overdraft protection depending on how Bank of America processes them. Recurring bills and automatic payments are usually covered, but confirm this with your bank if you are relying on overdraft protection for a specific payment.

If your linked account does not have enough money to cover the overdraft, the transfer fails and you are back to standard overdraft fees. For example, if your checking account is $200 short and your linked savings account only has $50, the bank transfers the $50 and you still owe the overdraft fee on the remaining $150.

Alternatives to overdraft protection

The simplest alternative is to not use overdraft protection or standard overdraft service at all. You can turn off overdraft service in your account settings so transactions are simply declined if you do not have funds. This prevents fees but means your debit card will be rejected at the register or your check will bounce.

Another option is to set up low-balance alerts through your Bank of America app so you get a notification when your account drops below a certain amount. This gives you time to transfer money in or adjust your spending before you actually overdraft. Many people use this alongside overdraft protection as a safety net.

If overdrafts are a recurring problem, the underlying issue is usually a mismatch between your income timing and your bill timing. A budget that accounts for when money comes in and when bills leave can prevent overdrafts altogether, even without protection.

Frequently Asked Questions

Does Bank of America automatically enroll me in overdraft protection?

No. Bank of America requires you to turn on overdraft protection yourself through your account settings or by calling customer service. If you do not set it up, you have standard overdraft service instead, which charges a fee when transactions post against insufficient funds.

Can I use overdraft protection with a credit card instead of a savings account?

Yes, you can link a Bank of America credit line or credit card as your overdraft protection source. Transfers are treated as cash advances and accrue interest immediately at the cash advance rate, which is typically higher than the regular purchase rate.

What is the difference between overdraft protection and overdraft fees?

Overdraft protection prevents overdrafts by automatically transferring money from a linked account, with no fee for the transfer itself. Overdraft fees charge you money when a transaction posts against insufficient funds. You choose which system you want; overdraft protection costs nothing to use but requires setup.

Will overdraft protection stop working if I run out of money in my linked account?

Yes. If your linked savings account does not have enough to cover the overdraft, the transfer fails and you incur a standard overdraft fee on the shortfall. Overdraft protection only works if the linked account has available funds.

Can I turn off overdraft protection after I set it up?

Yes. You can disable overdraft protection anytime through your account settings or by calling Bank of America. Once it is off, standard overdraft fees apply if you overdraft, or transactions are declined if you have overdraft service turned off entirely.
