You can charge fees if other check / ACH items are a part of the overdraft balance. See this section of the commentary on 205.17
9. Daily or Sustained Overdraft, Negative Balance, or Similar Fee or Charge
i. Daily or sustained overdraft, negative balance, or similar fees or charges. If a consumer has not opted into the institution’s overdraft service for ATM or one-time debit card transactions, the fee prohibition in § 205.17(b)(1) applies to all overdraft fees or charges for paying those transactions, including but not limited to daily or sustained overdraft, negative balance, or similar fees or charges. Thus, where a consumer’s negative balance is solely attributable to an ATM or one-time debit card transaction, the rule prohibits the assessment of such fees unless the consumer has opted in. However, the rule does not prohibit an institution from assessing daily or sustained overdraft, negative balance, or similar fees or charges if a negative balance is attributable in whole or in part to a check, ACH, or other type of transaction not subject to the fee prohibition. When the negative balance is attributable in part to an ATM or one-time debit card transaction, and in part to a check, ACH, or other type of transaction not subject to the fee prohibition, the date on which such a fee may be assessed is based on the date on which the check, ACH, or other type of transaction is paid into overdraft.
ii. Examples. The following examples illustrate how an institution complies with the fee prohibition. For each example, assume the following:
(a) the consumer has not opted into the payment of ATM or one-time debit card overdrafts; (b) these transactions are paid into overdraft because the amount of the transaction at settlement exceeded the amount authorized or the amount was not submitted for authorization; (c) under the account agreement, the institution may charge a per-item fee of $20 for each overdraft, and a one-time sustained overdraft fee of $20 on the fifth consecutive day the consumer’s account remains overdrawn; (d) the institution posts ATM and debit card transactions before other transactions; and (e) the institution allocates deposits to account debits in the same order in which it posts debits.
a. Assume that a consumer has a $50 account balance on March 1. That day, the institution posts a one-time debit card transaction of $60 and a check transaction of $40. The institution charges an overdraft fee of $20 for the check overdraft but cannot assess an overdraft fee for the debit card transaction. At the end of the day, the consumer has an account balance of negative $70. The consumer does not make any deposits to the account, and no other transactions occur between March 2 and March 6. Because the consumer’s negative balance is attributable in part to the $40 check (and associated overdraft fee), the institution may charge a sustained overdraft fee on March 6 in connection with the check.
b. Same facts as in a., except that on March 3, the consumer deposits $40 in the account. The institution allocates the $40 to the debit card transaction first, consistent with its posting order policy. At the end of the day on March 3, the consumer has an account balance of negative $30, which is attributable to the check transaction (and associated overdraft fee). The consumer does not make any further deposits to the account, and no other transactions occur between March 4 and March 6. Because the remaining negative balance is attributable to the March 1 check transaction, the institution may charge a sustained overdraft fee on March 6 in connection with the check.
c. Assume that a consumer has a $50 account balance on March 1. That day, the institution posts a one-time debit card transaction of $60. At the end of that day, the consumer has an account balance of negative $10. The institution may not assess an overdraft fee for the debit card transaction. On March 3, the institution pays a check transaction of $100 and charges an overdraft fee of $20. At the end of that day, the consumer has an account balance of negative $130. The consumer does not make any deposits to the account, and no other transactions occur between March 4 and March 8. Because the consumer’s negative balance is attributable in part to the check, the institution may assess a $20 sustained overdraft fee. However, because the check was paid on March 3, the institution must use March 3 as the start date for determining the date on which the sustained overdraft fee may be assessed. Thus, the institution may charge a $20 sustained overdraft fee on March 8.
iii. Alternative approach. For a consumer who does not opt into the institution’s overdraft service for ATM and one-time debit card transactions, an institution may also comply with the fee prohibition in § 205.17(b)(1) by not assessing daily or sustained overdraft, negative balance, or similar fees or charges unless a consumer’s negative balance is attributable solely to check, ACH or other types of transactions not subject to the fee prohibition while that negative balance remains outstanding. In such case, the institution would not have to determine how to allocate subsequent deposits that reduce but do not eliminate the negative balance. For example, if a consumer has a negative balance of $30, of which $10 is attributable to a one-time debit card transaction, an institution complies with the fee prohibition if it does not assess a sustained overdraft fee while that negative balance remains outstanding.
