Credit card fee and taxes
Credit card fees on a credit card used for personal expenses are not tax deductible. Credit card fees on a business credit card are deductible on schedule C (or whatever form you're using to report business income and expenses). If you are using the same card for both business and personal ... well, for starters, this is a very bad idea, because it creates exactly the question you're asking. If that's what you're doing, stop, and get separate business and personal cards. If you have separate business and personal cards -- and use the business card only for legitimate business expenses -- then the answer is easy: You can claim a schedule C deduction for any service charges on the business card, and you cannot claim any deduction for any charges on the personal card. In general, though, if you have an expense that is partly business and partly personal, you are supposed to figure out what percentage is business, and that is deductible. In an admittedly brief search, I couldn't find anything specifically about credit cards, but I did find this similar idea on the IRS web site: Generally, you cannot deduct personal, living, or family expenses. However, if you have an expense for something that is used partly for business and partly for personal purposes, divide the total cost between the business and personal parts. You can deduct the business part. For example, if you borrow money and use 70% of it for business and the other 30% for a family vacation, you can deduct 70% of the interest as a business expense. The remaining 30% is personal interest and is not deductible. Refer to chapter 4 of Publication 535, Business Expenses, for information on deducting interest and the allocation rules. (https://www.irs.gov/businesses/small-businesses-self-employed/deducting-business-expenses) So, PROBABLY, you could add up all the charges you made on the card, figure out how much was for business and how much for personal, calculate the business percentage, and then deduct this percentage of the service fees. If the amount involved is not trivial, you might want to talk to an accountant or a lawyer.
