Bank of America allows overdrafts through two separate systems: overdraft protection linked to another account or credit line, and standard overdraft coverage on debit card and check transactions.

Bank of America does not automatically overdraft your checking account. Instead, you choose whether to enroll in overdraft protection, which lets the bank cover transactions that would otherwise bounce. Without it, your debit card will decline and checks will be returned unpaid. With it, you pay a fee but the transaction goes through.

The distinction matters because the two systems work differently, cost different amounts, and protect different types of payments. Knowing which one you have—or whether you have either—determines what happens when your balance drops below zero.

Key Takeaways

  • Bank of America offers overdraft protection by linking your checking account to a savings account, money market account, or credit line, which covers shortfalls automatically.
  • Standard overdraft coverage applies only to checks and debit card purchases at merchants, not ATM withdrawals or online bill payments, and costs $35 per transaction.
  • Overdraft protection transfers from a linked account are free if you have funds available, but if the linked account also runs short, both accounts overdraft and you pay fees on both.
  • You must enroll in overdraft protection; Bank of America does not activate it by default, and you can turn it off at any time through online banking or by calling customer service.
  • If you decline overdraft protection, transactions that exceed your balance will be declined at the point of sale, and you will not be charged a fee.

Overdraft Protection Linked to Another Account

This is the primary overdraft tool Bank of America offers. You link your checking account to a savings account, money market account, or credit line in your name. When a transaction would overdraft your checking account, the bank automatically transfers funds from the linked account to cover it.

If the linked account has sufficient funds, the transfer is free. You simply lose the money from savings and keep your checking balance positive. If the linked account does not have enough to cover the full shortfall, Bank of America will transfer what is available and then charge you an overdraft fee on the checking account for the remaining amount.

You set up this protection through online banking under account settings or by visiting a branch. You can choose which account to link and change or remove the link at any time. Bank of America does not enroll you automatically; you must request it.

Standard Overdraft Coverage on Debit and Check Transactions

This is separate from overdraft protection. Standard overdraft coverage allows the bank to pay debit card purchases and checks even when your balance is insufficient. Each transaction that overdraws your account costs $35. There is no limit to how many overdraft fees you can incur in a single day, though Bank of America does cap the total number of fees per day at a level that varies by account type.

This coverage does not apply to ATM withdrawals, online bill payments, or ACH transfers. Those transactions will simply decline if you lack funds. Standard overdraft coverage is opt-in, meaning you must enroll to receive it. If you do not enroll, debit card transactions and checks will be declined when your balance is insufficient.

You can enroll or decline standard overdraft coverage through online banking or by calling customer service. The choice is separate from overdraft protection; you can have one, both, or neither.

When Overdraft Protection Fails

If your checking account is linked to a savings account for overdraft protection, and both accounts run short at the same time, both will overdraft. You will be charged a $35 overdraft fee on the checking account and another $35 fee on the savings account. This can happen if you have a large transaction that drains both accounts, or if you make multiple transfers that exhaust the linked account before the checking account recovers.

If you have overdraft protection linked to a credit line instead of a deposit account, the credit line will cover the shortfall, but you will owe interest on the borrowed amount at your credit line's rate. This is typically higher than the cost of a single overdraft fee, so it matters whether the shortfall is temporary or prolonged.

Overdraft Fees and Daily Limits

Bank of America charges $35 per overdraft transaction if you use standard overdraft coverage. The bank also limits the total number of overdraft fees per day; the exact limit depends on your account type and whether you are a preferred customer, but it typically ranges from three to five fees per day. This means you could incur $105 to $175 in overdraft fees in a single day if you make multiple transactions that overdraft your account.

Overdraft protection transfers from a linked account do not incur a fee if funds are available. If the linked account is also overdrawn, you pay the standard $35 overdraft fee on the checking account only, not on the transfer itself.

How to Enroll or Decline Overdraft Protection

Log into your Bank of America online account and navigate to account settings or account management. Look for overdraft protection or overdraft coverage options. You will see separate toggles or enrollment options for overdraft protection (linked account transfers) and standard overdraft coverage (debit and check transactions).

To link an account for overdraft protection, select the checking account you want to protect, then choose which savings, money market, or credit line account to link. Confirm the selection and the link becomes active immediately.

To enroll in standard overdraft coverage, find the overdraft coverage section and select opt-in. You can also call Bank of America customer service at the number on the back of your card and ask a representative to enroll you or make changes.

What Happens If You Decline Overdraft Protection

If you do not enroll in overdraft protection or standard overdraft coverage, transactions that exceed your available balance will be declined. A debit card purchase will fail at the register. A check will be returned unpaid to the person who deposited it, and they may charge you a returned-check fee. An online bill payment or ACH transfer will not go through.

You will not be charged an overdraft fee, but you also will not have a safety net if you miscalculate your balance. Some people prefer this because it prevents accidental overspending; others find it inconvenient when a legitimate transaction is declined.

Frequently Asked Questions

Can I overdraft my Bank of America account without enrolling in overdraft protection?

Only if you enroll in standard overdraft coverage, which allows debit card purchases and checks to overdraft for a $35 fee per transaction. ATM withdrawals and online bill payments will always be declined if you lack funds, regardless of your overdraft settings. Overdraft protection is not automatic.

Will Bank of America overdraft my account if I link it to a savings account with no money in it?

No. If the linked savings account is empty, the bank will transfer nothing and charge you an overdraft fee on the checking account for the shortfall. Linking an account does not may provide coverage; it only allows the bank to attempt a transfer if funds are available.

How long does an overdraft transfer take?

Transfers between your own Bank of America accounts are immediate. The funds move within minutes, and your checking balance updates right away. If you link a credit line, the credit is also instant.

Can I set a limit on how much Bank of America will overdraft?

No. Bank of America does not offer a spending limit or overdraft cap. You can only choose to enroll in overdraft protection or decline it entirely. If enrolled, the bank will cover transactions up to your available credit or linked account balance.

What if I overdraft and then deposit money the same day?

The deposit will first cover the overdraft balance, then any remaining amount becomes your new available balance. Overdraft fees are not reversed by deposits; you still owe the $35 fee even if you deposit money later that day.
