Re: What can I expense? Credit card balance, or amount I've paid towards credit card

If your accounting is on an accrual-basis, then you can base it off the charges over the course of the year. Even if you did a cash-basis accounting, you can't necessarily deduct 100% of the payments because some of the charges might not be 100% deductible like meals, shared utilities in a home office, car expenses if also used for personal use, cell phone if personal calls are made, etc.
