Hello, I am entering a persons expenses for the year. I will then print a report and give to him for his accountant. My question has to do with credit card interest. His credit card has mostly business expenses, and some personal expenses. How do I post this? Orinally I took each statement and found the percentage of business & personal expenses and applied that percentage to that credit card interest charge. Now, as I am thinking about it, this is not right. I am totally confused as to how to handle this. Should I total the business expenses for the year & use that interest rate? Am I able to write off the interest every month even though the interest for certain expenses were created the month before? I looked at his tax return from last year & the interest was only about $3000. Only a fraction as to what he paid. I appreciate any feedback you can provide. Thank you, Wendy
