Can I write off credit card processing fees?

Credit card processing fees can be deducted as a business expense if they are incurred in the process of running a business. This includes fees charged by credit card companies for processing customer payments. However, these fees are not deductible for personal expenses. For example, if you own a retail store and pay a percentage of each sale to a credit card processor, this fee is deductible. Conversely, if you incur a processing fee on a personal purchase, it is not deductible.
