Can I write off business bank account fees?

Business bank account fees can be deducted as a business expense if the account is used solely for business purposes. This includes monthly maintenance fees, transaction fees, and charges for overdrafts. However, if the account is used for both personal and business purposes, only the portion of the fees attributable to business use is deductible. For example, if 70% of the transactions in the account are business-related, then 70% of the fees can be deducted.
